High Medical Costs Fuel Missed Care

More than 40% of adults in the United States went without necessary medical care in 2010 due to cost, up from 29% a decade ago, according to the Commonwealth Fund’s Biennial Health Insurance Survey.

Skipping needed care such as prescription drugs, specialist visits, and follow-up treatment is even more common among moderate- and low-income groups. For example, 56% of Americans with household incomes under 200% of the federal poverty level went without necessary care last year, according to the survey, which was released on March 16.

The survey, which was conducted from July through November 2010, is based on phone interviews with a nationally representative sample of more than 4,000 U.S. adults aged 19 and older. The analysis is limited to the approximately 3,000 adults aged 19-64 years who responded to the survey.

Cost was an issue for those with and without health insurance. About two-thirds of adults who were uninsured during 2010 said they had trouble accessing care due to cost; 31% of insured respondents reported the same problem.

Preventive care also took a hit in 2010. Only half of adults surveyed reported that they were up to date on five recommended screening tests: blood pressure and cholesterol tests, mammograms, colon cancer screenings, and Pap tests. Those with lower incomes were less likely to get screened: While 65% of adults with a household income at or above 400% of the federal poverty level were up-to-date, only 36% of adults at less than 133% of the federal poverty level were.

"The survey findings paint a dire picture of the degree to which low- and moderate-income families are currently burdened by costs of care and the degree to which a severe economic crisis can affect the health security of working families," Sara R. Collins, Ph.D., vice president for Affordable Health Insurance at the Commonwealth Fund, said during a press conference to release the findings.

Dr. Collins said the controversial Affordable Care Act will help to address some of the problems highlighted in the survey by alleviating the cost burden on the lowest-income Americans. She cited the expansion of the Medicaid program and federal subsidies to purchase private health coverage, both of which begin in 2014, as ways to reduce out-of-pocket costs and improve access to care.

The Commonwealth Fund report also noted worsening trends in insurance coverage and medical debt over the last decade:

  • About 28% of adults in the United States were uninsured for part of 2010, up from 24% in 2001.
  • About 40% of adults reported that they had problems paying their medical bills in 2010, up from 34% in 2005.
  • About 32% of Americans spent 10% or more of their household income on out-of-pocket costs and premiums in 2010. This is up from 23% in 2005 and 21% in 2001.

Reassure Dying Patients About Discontinuing Drugs

VANCOUVER, B.C. – Withdrawing medications at the end of life is often the right thing to do clinically, but it can make hospice patients feel abandoned, according to nurse Beverly Lunsford, Ph.D.

"People have it hammered in their heads to take their diabetes medications, their hypertension medications, and have done it faithfully for [decades]. Now you’re telling them to stop. They may have a real sense that isn’t right. Families may perceive medication discontinuation as substandard care or lack of care," said Dr. Lunsford, who coordinates the graduate program for palliative care nurse practitioners at George Washington University in Washington.

It’s important to reassure patients and families that’s not the case or, better yet, handle the situation in such a way that they don’t think so in the first place, Dr. Lunsford said at the annual meeting of the American Academy of Hospice and Palliative Care Medicine.

A review with the patient of his or her medications is a good place to start, said Dr. Robert Kaiser, associate geriatrics and palliative care professor at the university. In such "brown-bag reviews," patients bring in every medication they take, including nutritional supplements and other over-the-counter preparations. Clinicians then check whether the drugs’ original indications still apply and ask about side effects and adherence. Most hospice patients need such attention as they typically are on at least five drugs at admission to hospice, with more added for comfort care, Dr. Kaiser said.

Medication issues should also be incorporated into goals-of-care discussions, said Dr. Lunsford. When patients opt for comfort care, "you might sort out with them which medications they are taking for symptom relief and what medications they are taking for treating medical conditions" that are no longer a high priority, such as hypercholesterolemia, she said.

A patient might be more open to this discussion if a clinician points out that the person’s medical condition has changed – that he or she has lost weight, for instance – so certain drugs are less necessary. Once-tolerated doses may be too potent because of loss of kidney or liver function. Difficulty swallowing and memory loss may also make adherence increasingly burdensome, Dr. Kaiser said.

The goal is to cut unneeded medications so side effects, such as falls and confusion, and drug interactions don’t add discomfort to the dying process, he said. Picking which drugs to stop, however, is not an exact science. Life expectancy, how a drug meets care goals, and how long a drug takes to work are among some of the factors to consider.

Dr. Lunsford and Dr. Kaiser recommended several guides to withdrawing drugs at the end of life. The Medication Appropriateness Index, a 10-question tool for gauging appropriate drug use, can help, they said, as can the list of drugs and dosages to avoid in the elderly according to the Beers criteria (Arch. Intern. Med. 2006;166:605-9).

They cited other references making the point that drugs for chronic conditions may reasonably be discontinued. Statins, bisphosphonates, and cholinesterase inhibitors may be stopped in patients with advanced dementia, poor prognoses, or both, they said, and cholinesterase inhibitors and memantine may be discontinuation candidates because the evidence is marginal for their benefit in advanced dementia patients entering hospice or other palliative care (End of Life/Palliative Education Resource Center. Fast Fact and Concept #174 "Dementia Medications in Palliative Care," www.eperc.mcw.edu). Opioids, beta-blockers, clonidine, gabapentin, selective serotonin reuptake inhibitors, serotonin-norepinephrine reuptake inhibitors, and tricyclic antidepressants, among others, require tapering, said Dr. Lunsford and Dr. Kaiser, citing a recent study (JAMA 2010;304:1592-601). A drug holiday may be appropriate when there is uncertainty about withdrawing a medication, Dr. Kaiser said.

Dr. Lunsford cautioned that "many health care professionals may not feel they have the time" to decide what drugs to stop, negotiate the issue with the patient, taper doses, and monitor outcomes on subsequent visits. It’s important to do so, however, and to prevent conflict with peers by keeping them in the loop when discontinuing drugs, she said.

"You need to get them on the same page. Get the case manager involved if you’re not in direct contact with these people, or pick up the phone and [let them know] this is what your suggesting," she said.

Neither Dr. Lunsford nor Dr. Kaiser made conflict-of-interest disclosures.

Mandatory Screening Increases Palliative Care, Cuts Costs

VANCOUVER, B.C. – Within a year of implementation, mandatory palliative care screening significantly increased palliative care consults at St. John Hospital and Medical Center in Detroit.

The increased use of palliative care services saved the hospital about $700,000 in fiscal year 2008, because of shorter lengths of stay and patients opting for less-heroic care, among other factors.

As a result, St. John Providence Health System now screens patients admitted to St. John and its other four hospitals for palliative care needs, and is incorporating screening into its electronic health record (EHR) system, said nurse Elizabeth DiStefano, the system’s palliative care coordinator.

Planning for the screening program started in 2006 after hospital administrators realized that not all eligible patients were referred for palliative care consults at the five hospitals.

They decided to test-pilot mandatory screening at St. John to see if it would help, collaborating on the project with the Duke Institute on Care at the End of Life, Durham, N.C. The goal was to "increase access to palliative care," Ms. DiStefano said.

A multidisciplinary working group developed a two-page screening checklist and tested it in St. John’s 20-bed medical intensive care unit, an oncology unit, and two medical units, starting in April 2007.

After a year, they streamlined the checklist down to nine items, any one of which triggered a consult.

Mandatory screening had a significant impact. In 2006, before it was implemented, there were 444 palliative care consults; the number increased to 742 in 2007 and to 952 in 2008. The time from admission to consult dropped from about 9 days to about 6.

The success led to a systemwide rollout of palliative care screening, with the nine triggers now assessed in patients admitted to the health system’s five hospitals.

The nine triggers are:

• Code status changed to "do not resuscitate."

• Conflict about starting or stopping life-prolonging treatment.

• Discussion about goals of care or code status, and/or surrogate distress about decision making.

• A marked decrease in functional status within 2 months.

• Uncontrolled symptoms, such as pain or nausea, interfering with quality of life.

• Consideration of percutaneous endoscopic gastronomy tube placement.

• Admission from an extended-care facility with dependence for activities of daily living.

• Nonambulatory dementia with no speech, or with recurrent aspiration pneumonia.

• A patient or family request for palliative care.

The screening "identifies patients further upstream" who need services, "so it isn’t just end-of-life patients," Ms. DiStefano said.

Palliative care staffing varies at the hospitals based on size. At the 650-bed St. John Hospital, two nurse practitioners, a physician, a medical social worker, and a chaplain help with symptom management, discharge planning, advance directives, and other issues, such as spiritual and emotional needs.

Both patients and families "appreciate there’s a team effort [that looks after] the whole family, putting the whole picture together" to improve quality of life, Ms. DiStefano said.

Palliative care is cash-flow positive as well, with the savings covering the costs, and then some.

But for such a program to work, palliative care screening must be easily incorporated into existing procedures, she said.

For that reason, a mandatory field is being added to her health system’s EHR system that requires nurses to assess the nine triggers at admission, then again 5 days later. When a patient screens positive, the system sends an alert to the attending physician’s e-mail in-box asking for a palliative care referral order.

With the paper system, the triggers are assessed only at admission, and nurses call attendings when patients screen positive, she said.

Some physicians resisted palliative care during the pilot, thinking they could do a better job tending to patients’ needs themselves, or mistaking palliative care for hospice care.

One ICU doctor was reluctant to call in the palliative care team for a young patient. When asked why, he said he thought the 20-year-old patient was too young for hospice, Ms. DiStefano said.

When she explained that the team would talk to the patient and family about symptom control and quality of life, the physician became one of the team’s biggest supporters, Ms. DiStefano said.

The pilot was funded by local foundations and hospital administrators. Ms. DiStefano said she had no financial disclosures.

The screening "identifies patients further upstream" who need services, "so it isn’t just end-of-life patients," Ms. DiStefano said.

Palliative care staffing varies at the hospitals based on size. At the 650-bed St. John Hospital, two nurse practitioners, a physician, a medical social worker, and a chaplain help with symptom management, discharge planning, advance directives, and other issues, such as spiritual and emotional needs.

Both patients and families "appreciate there’s a team effort [that looks after] the whole family, putting the whole picture together" to improve quality of life, Ms. DiStefano said.

Palliative care is cash-flow positive as well, with the savings covering the costs, and then some.

But for such a program to work, palliative care screening must be easily incorporated into existing procedures, she said.

For that reason, a mandatory field is being added to her health system’s EHR system that requires nurses to assess the nine triggers at admission, then again 5 days later. When a patient screens positive, the system sends an alert to the attending physician’s e-mail in-box asking for a palliative care referral order.

With the paper system, the triggers are assessed only at admission, and nurses call attendings when patients screen positive, she said.

Some physicians resisted palliative care during the pilot, thinking they could do a better job tending to patients’ needs themselves, or mistaking palliative care for hospice care.

One ICU doctor was reluctant to call in the palliative care team for a young patient. When asked why, he said he thought the 20-year-old patient was too young for hospice, Ms. DiStefano said.

When she explained that the team would talk to the patient and family about symptom control and quality of life, the physician became one of the team’s biggest supporters, Ms. DiStefano said.

The pilot was funded by local foundations and hospital administrators. Ms. DiStefano said she had no financial disclosures.

Improving Access to Pediatric Palliative Care

Dr. Stefan J. Friedrichsdorf has a list of "myths" about pediatric palliative care that he presents during lectures. Among them: that the death of a child in the United States is a rare event, that pediatric palliative care is just for children with cancer, and that care starts when treatment stops.

In his lectures – and in his work every day at Children’s Hospitals and Clinics of Minnesota, Minneapolis – Dr. Friedrichsdorf debunks these myths.

    Dr. Savithri Nageswaran of Brenner Children's Hospital at Wake Forest University Baptist Medical Center in Winston-Salem, N.C., sees a patient.

In January, he was one of two pediatricians who won national awards from the Hastings Center and a partnering foundation for their contributions to the broader field of palliative care. He and pediatrician Dr. Savithri Nageswaran of Brenner Children’s Hospital at Wake Forest University Baptist Medical Center in Winston-Salem, N.C., joined two geriatricians and an internist in receiving the award.

The pain and palliative care program at Dr. Friedrichsdorf’s institution is a relatively long-standing program, but pediatric palliative care is a new subspecialty and is still a relatively new area of pediatric care and of palliative medicine – one for which delivery models and educational pathways are still evolving, and one for which reimbursement is poor and regulatory barriers are challenging.

"It’s truly interdisciplinary, in that people need to really go beyond what they’ve been trained for," said Dr. Friedrichsdorf, medical director of the department of pain medicine, palliative care & integrative medicine at Children’s. "I’m nothing without my team."

Pediatric palliative care has been defined and described by the World Health Organization, the Institute of Medicine, the American Academy of Pediatrics, and other bodies as individualized, integrative care that is provided for children with life-threatening conditions. The care starts at diagnosis, continues through the trajectory of the illness, and is directed at the underlying illness and at the physical, emotional, social, and spiritual needs of the child and family.

More than 15,000 children and teens die in the United States each year from life-limiting diseases – and less than a quarter of them have cancer, according to data cited by Dr. Friedrichsdorf. Neuromuscular or neurodegenerative disorders cause a significant proportion of those deaths, followed by congenital or genetic disorders, cardiovascular disorders, and metabolic disorders.

"The vast majority of these children do not have access to pediatric palliative care in this country," Dr. Friedrichsdorf said in an interview. Data show that these children are suffering needlessly from pain, breathlessness, nausea, and vomiting.

Praised by the awards committee for "innovative symptom management, compassion, and family-centered care," Dr. Friedrichsdorf said he and his team take "an extremely aggressive approach" to managing pain and distressing symptoms in children with either life-threatening or life-limiting conditions.

He believes strong pain medications are underused in children (and one of the "myths" he debunks is that increasing doses of opioids and/or benzodiazepines causes respiratory depression and quickens death), but also that pharmacology alone is insufficient.

His department employs both pharmacology and complementary therapies such as biofeedback, massage, hypnosis, acupuncture, and acupressure. Physicians and other staff are trained in such modalities. "It’s not one or the other. It’s using the whole breadth [of therapies] at the same moment," said Dr. Friedrichsdorf, who is trained in self-hypnosis.

"We want to promise each family, if your child is suffering from distressing symptoms like nausea, pain, or dyspnea, we can usually make these symptoms go away," he said. "Our goal is for children to live as long as possible, as well as possible."

In addition to physicians and nurses, the pain and palliative care team at Children’s includes social workers, psychologists, a physical therapist, a child-life specialist, massage therapists, and advanced practice nurses.

Each of these professionals can see patients as part of a hospital-based pain and palliative care "rounding team" in the department’s pain and palliative care clinic, or for patients in the Minneapolis/St. Paul area, in the home through the department’s home-based component. The team can be called upon by anyone – a doctor, a patient, a relative or friend – for a consultation, and its members meet regularly to discuss patients.

"My physical therapist may tell me, for instance, that I need to change [a patient’s] pain medications because she sees side effects," Dr. Friedrichsdorf said.

A pilot study of pediatric palliative care teams at eight children’s hospitals, to be published soon, found that professionals in the teams had a "clear idea of what the other professionals offered to the patient and family," said Nancy Berlinger, Ph.D., deputy director and research scholar at the Hastings Center, which conducted the study with researchers at Rush University, Chicago.

 

 

A chaplain knows, for instance, how the physician and nurse are addressing the patient’s medical needs, and the physician is aware that the chaplain is supporting the parents and, in some cases, the child, she said in an interview.

"Having shared goals of care and strong communication is also important so that everything doesn’t have to be explained every time a shift changes or a patient is transferred to a different setting," she said.

"Most of these pediatric palliative care teams are fairly newly established," she noted. "There was some pediatric palliative care before then, but not necessarily with a strong team approach."

Dr. Nageswaran, who led the establishment of the first pediatric palliative care program at her hospital in 2008, said she was struck by the amount of coordination needed to provide good palliative care and by the flexibility needed to design a good program.

She and her colleagues started the program as a consult service for children who were hospitalized with complicated, often life-limiting conditions. The service used a half-time nurse coordinator, a one-quarter full-time equivalent (FTE) clinician post to be shared by a handful of physicians for rotating on-call duty, and a 1% FTE post for a physician coordinator.

"Very soon, we realized that the biggest need was to facilitate collaboration between multiple providers and to ensure sufficient continuity of care as these children transition back and forth from the hospital to home," Dr. Nageswaran said in an interview. "We weren’t achieving this with the traditional consult model where we’d see patients in the hospital and leave recommendations for the primary medical team."

In a subsequent restructuring, physician time was consolidated into a one-third–time FTE coordinator post, which Dr. Nageswaran fills herself, and funding was obtained from the federal Maternal and Child Health Bureau to add another half-time nurse coordinator who could focus on making home visits and coordinating home-based care in one local county.

The flexibility to coordinate care outside the hospital is critical, Dr. Nageswaran said. One of the 235 children cared for under the palliative care program thus far was a child with a rare genetic disorder characterized by skeletal abnormalities, urologic abnormalities, and severe neurologic impairment and seizures.

"The family wanted end-of-life care to be delivered at home, but they didn’t want to forgo medical care," Dr. Nageswaran recalled. "We went step-by-step, aligning the family’s wishes with the care the child received. We worked with the primary care doctor, the subspecialists, the home health agency, and the parents to provide medical treatment, pain and symptom management, and other care at home."

Both she and Dr. Friedrichsdorf emphasized the value of open inquiry with parents, children and families.

"Each family is unique in how they perceive illness and how they make decisions about treatment and end-of-life care," said Dr. Nageswaran. "When we meet families, we meet them without a set agenda, and we make sure we don’t impose our structure."

Similarly, Dr. Friedrichsdorf said, "When I enter a room, the first thing I say is, ‘How can I help you?’ We start with that open question." At that point, he said, surveys or other structured tools can be used to help determine needs and care plans.

One of the thorns in the field of pediatric palliative care is the unavailability of hospice services for many children, given the prognostic uncertainty of most childhood life-threatening conditions and the desire for continued treatment. Currently, most families have to forgo home-health services in order to receive hospice services.

Some states have taken action; policy reform passed in California in 2006, for instance, makes it easier for parents to utilize the Medi-Cal hospice benefit for children. A section of the federal Patient Protection and Affordable Care Act, moreover, is expected to change the Medicaid system to allow children with life-limiting conditions to receive both hospice care and curative treatment.

Another problem is poor provider reimbursement. "Physician services are reimbursed, but not enough to account for the amount of time involved," said Dr. Nageswaran. "\"And the services of nurses and social workers, who are key to pediatric palliative care programs, are not reimbursed."

She jump-started her program with a grant from the Duke Endowment, a private foundation, but now relies primarily on financial support from the hospital. Dr. Friedrichsdorf estimates that his hospital is reimbursed for only about half of its costs, and says that it relies heavily on philanthropy to make up the difference.

Philanthropy recently benefited the pediatric palliative care program at Akron (Ohio) Children’s Hospital. With $1.2 million in donations from the Haslinger Family Foundation and other leadership gifts, the hospital has created an endowed chair for its services, which began in 2002.]

 

 

One goal in the meantime, said Dr. Berlinger, is to "influence the culture of health care so that pediatric palliative care is recognized as ethically mandatory."

The $15,000 awards that Dr. Nageswaran and Dr. Friedrichsdorf received were given by the Hastings Center, a bioethics research institute based in Garrison, N.Y., in partnership with the Cunniff-Dixon Foundation, a foundation that focuses on the doctor-patient relationship near the end of life.

Pediatric Palliative Care Training

In terms of education, pediatric palliative care might be where pediatric subspecialties such as pulmonary care or neonatology were 25 years ago, Dr. Friedrichsdorf said, with an initial cadre of trained physicians having emerged.

In 2008, 47 physicians were certified in Hospice and Palliative Medicine (HPM) by the American Board of Pediatrics after taking the first American Board of Medical Specialties–recognized examination for the subspecialty. In total, 1,274 physicians were certified by various boards in the new subspecialty.

The American Board of Medical Specialties (ABMS) approved the creation of HPM as a subspecialty of 10 participating boards in 2006. Prior to 2006, board certification in hospice and palliative medicine was administered by the American Board of Hospice and Palliative Medicine but not recognized by the ABMS.

Other pediatricians have taken courses and attended educational retreats through organizations such as the Initiative for Pediatric Palliative Care, Dr. Berlinger said.

Ideally, she and Dr. Friedrichsdorf say, both educational tracks – fellowships and educational opportunities for mid-career pediatricians – will grow.

Starting in 2013, physicians who want to sit for the HPM board exam will have to have completed an Accreditation Council for Graduate Medical Education-accredited fellowship – a change that should spur the development of more fellowship programs. Children’s Hospitals and Clinics of Minnesota, Dr. Friedrichsdorf’s hospital, houses one of a handful of fellowship programs in pediatric palliative care. It has applied for ACGME approval.

Dr. Friedrichsdorf is the principal investigator of a National Institutes of Health/National Cancer Institute study on the creation and implementation of a pediatric palliative care curriculum that is slated to be offered to physicians who are in the midst of their careers and not seeking subspecialty training.

"Many professionals working in children’s hospitals are likely to care for a dying child, and need to be comfortable and knowledgeable," said Dr. Friedrichsdorf, who completed a fellowship in pediatric pain and palliative care at the Children’s Hospital at Westmead, Australia, after finishing his pediatric residency in Germany.

Philanthropy recently benefited the pediatric palliative care program at Akron (Ohio) Children’s Hospital. With $1.2 million in donations from the Haslinger Family Foundation and other leadership gifts, the hospital has created an endowed chair for its services, which began in 2002.]

 

 

One goal in the meantime, said Dr. Berlinger, is to "influence the culture of health care so that pediatric palliative care is recognized as ethically mandatory."

The $15,000 awards that Dr. Nageswaran and Dr. Friedrichsdorf received were given by the Hastings Center, a bioethics research institute based in Garrison, N.Y., in partnership with the Cunniff-Dixon Foundation, a foundation that focuses on the doctor-patient relationship near the end of life.

Pediatric Palliative Care Training

In terms of education, pediatric palliative care might be where pediatric subspecialties such as pulmonary care or neonatology were 25 years ago, Dr. Friedrichsdorf said, with an initial cadre of trained physicians having emerged.

In 2008, 47 physicians were certified in Hospice and Palliative Medicine (HPM) by the American Board of Pediatrics after taking the first American Board of Medical Specialties–recognized examination for the subspecialty. In total, 1,274 physicians were certified by various boards in the new subspecialty.

The American Board of Medical Specialties (ABMS) approved the creation of HPM as a subspecialty of 10 participating boards in 2006. Prior to 2006, board certification in hospice and palliative medicine was administered by the American Board of Hospice and Palliative Medicine but not recognized by the ABMS.

Other pediatricians have taken courses and attended educational retreats through organizations such as the Initiative for Pediatric Palliative Care, Dr. Berlinger said.

Ideally, she and Dr. Friedrichsdorf say, both educational tracks – fellowships and educational opportunities for mid-career pediatricians – will grow.

Starting in 2013, physicians who want to sit for the HPM board exam will have to have completed an Accreditation Council for Graduate Medical Education-accredited fellowship – a change that should spur the development of more fellowship programs. Children’s Hospitals and Clinics of Minnesota, Dr. Friedrichsdorf’s hospital, houses one of a handful of fellowship programs in pediatric palliative care. It has applied for ACGME approval.

Dr. Friedrichsdorf is the principal investigator of a National Institutes of Health/National Cancer Institute study on the creation and implementation of a pediatric palliative care curriculum that is slated to be offered to physicians who are in the midst of their careers and not seeking subspecialty training.

"Many professionals working in children’s hospitals are likely to care for a dying child, and need to be comfortable and knowledgeable," said Dr. Friedrichsdorf, who completed a fellowship in pediatric pain and palliative care at the Children’s Hospital at Westmead, Australia, after finishing his pediatric residency in Germany.

In Hospice Patients, Discuss Defibrillators Immediately

VANCOUVER, B.C. - People with implanted cardioverter defibrillators should be given the option of having the devices deactivated when they enter hospice care, Dr. Bernard Lee told his audience at the annual meeting of the American Academy of Hospice and Palliative Care Medicine.

When avoidance of sudden death is no longer the goal, deactivation of the devices to prevent shocking patients as their hearts fail "is ethically the right thing to do," said Dr. Lee, associate chief medical officer of hospice and palliative care at the Metropolitan Jewish Health System in Brooklyn, N.Y.

Although the issue has gotten some attention in recent years, research has shown that fewer than half of implanted cardioverter defibrillators (ICDs) are deactivated in hospice patients, said Dr. Lee (Ann. Intern. Med. 2010;152:296-9).

"We are not really doing a good job," said Dr. Michael Mencias, also of Metropolitan Jewish Health System. Even if the patient is unconscious and can’t feel the painful jolts, his or her body will jerk with each shock, alarming family members and making them feel that they didn’t make the patient’s final hours as comfortable as possible.

Often, patients and families – sometimes even providers – don’t know that ICDs can be painlessly deactivated magnetically and that doing so may prevent havoc at the end of life. And not infrequently, families have the mistaken impression that deactivation equals euthanasia or physician-assisted suicide, said Dr. Lee and Dr. Mencias.

Pacing Function Left Active

Palliative care and hospice clinicians can do better, the speakers said. A position statement from the National Organization of Hospice and Palliative Care gives tips on how to handle the issue (www.nhpco.org/files/public/NHPCO_ICD_position_statement_May08.pdf). In short, the group recommends asking all patients or families at hospice admission (or as soon as possible) whether a defibrillator has been implanted.

The group says that a health professional should then explain the potential problems if an ICD is not deactivated, and that deactivation is not likely to hasten death. When a patient has decided whether to keep the device turned on, everyone on the medical team should be so informed, says the statement.

The ICD’s detection of ventricular tachycardia or fibrillation – the function that tells the device to fire – can be deactivated either by a manufacturer’s technician or (less permanently) by a medical professional who can secure a magnet over the device. Available from ICD makers, the magnets are strong and measure a few inches across. They deactivate the sensing function, but that function returns if the magnet is removed.

When a patient’s time is short, Dr. Lee said he tries to quickly pull together a family meeting to discuss deactivation. "In worst-case scenarios, it’s done over the phone with the hospice physician and the patient or health care surrogate," he added.

For hospice patients at home, a magnet can be left with the family, with instructions on how to tape it to the chest to stop body-jolting shocks. Home-visiting nurses in Dr. Lee’s organization carry magnets in their cars in case a patient who is dying at home needs one quickly.

The application of magnets to a patient’s chest, however, is "certainly not a long-term solution for somebody who’s not actively dying," Dr. Lee said. Especially for frail patients who have lost weight, a magnet taped to the chest is uncomfortable, he added.

Deactivation Hesitation

Dr. Lee said that his organization broaches the topic of deactivation within 5 days of a patient’s admission to hospice. If the person opts for deactivation, the device’s manufacturer is called.

Often patients will have lost the card that came with their ICD, said Dr. Lee, so it’s necessary to call the various manufacturers – typically Medtronics, Guidant/Boston Scientific, and St. Jude Medical – to find out what device the patient carries. The companies will have a record.

Technicians will make house calls, if necessary, to deactivate an ICD’s sensing function in the presence of a licensed medical professional, and they can return to reactivate it if the patient changes his or her mind.

Deactivation usually requires a hospice physician’s order, said Dr. Lee. "Most physicians in the community are not comfortable writing that order."

Technicians themselves may even hesitate to deactivate an ICD. "Some of them are uncomfortable, so they will hand you the laptop and say ‘here, click on deactivate.’ We end up doing it," Dr. Mencias said.

Dr. Lee and Dr. Mencias said they have no conflict of interest.

Malignant bowel obstruction: Individualized treatment near the end of life

Malignant bowel obstruction: Individualized treatment near the end of life

Malignant bowel obstruction occurs in 5% to 51% of women with ovarian cancer and in 10% to 28% of patients with gastrointestinal cancer, predominantly in the advanced stages.1 Median survival after its onset ranges from 30 to 90 days.2–5

Its symptoms are challenging to manage, since nausea, vomiting, colic, and abdominal pain, which are common, cause significant physical distress and demoralization. The decision whether to correct it with surgery requires an individualized approach and a clear understanding of the goals of care and expected survival in the individual patient.

This review focuses on the management of inoperable malignant bowel obstruction and includes discussion of hydration, nutrition, and endoscopic palliative options.

WHAT ARE THE DIFFERENT TYPES OF OBSTRUCTION?

Bowel obstruction may be mechanical or functional, partial or complete, and may occur at one or at many sites. Tumors can impair bowel function in several ways6–8:

  • Intraluminal tumors can occlude the lumen or act as a point of intussusception.
  • Intramural tumors can extend to the mucosa and obstruct the lumen or impair peristalsis.
  • Mesenteric and omental masses or malignant adhesions can kink or angulate the bowel, creating an extramural obstruction.
  • Tumors that infiltrate into the mesentery, bowel muscle, or the enteric or celiac plexus can cause dysmotility.

Cholangiocarcinoma, pancreatic carcinoma, and gallbladder carcinoma are the most common tumors causing duodenal obstruction.9 Distal obstruction is caused mainly by colon and ovarian cancer.

Obstruction can be due to treatment

In a minority of patients, obstruction is unrelated to the cancer and is instead due to adhesions arising from surgery, radiation therapy (causing enteritis and strictures), desmoplastic reactions to intraperitoneal chemotherapy, torsion, or internal hernias.10–12

In rare cases, a patient has intestinal pseudo-obstruction from paraneoplastic destruction of enteric neurons, or severe ileus from anticholinergic or sympathomimetic drugs, as seen with acute colonic pseudo-obstruction (Ogilvie syndrome).13

Physiologic reactions to obstruction

Malignant bowel obstruction stimulates gastric, biliary, pancreatic, and intestinal secretions, decreases intraluminal sodium and water reabsorption, and increases mucosal sodium and water secretion.6,14 In response to the obstruction, peristalsis increases, and prostaglandin, vasoactive intestinal peptide, and nociceptive mediators are released. Vasoactive intestinal polypeptide perpetuates a cycle of secretion, distention, and contraction that leads to intestinal hyperemia, bowel edema, and accumulation of fluid in the lumen.8,10,11,15

Signs and symptoms depend on the site

The site of obstruction determines the signs and symptoms patients experience.7,14 Obstructions high in the gastrointestinal tract are associated with greater symptoms but fewer signs than colonic obstructions.1 Patients with proximal small-bowel obstruction have more severe nausea and a greater number of episodes of emesis, but they have relatively normal plain radiographs of the abdomen, which do not have the characteristic air-fluid levels commonly seen with distal small-bowel obstruction.

Most malignant obstructions remain partial, but increasing abdominal distention, worsening nausea, vomiting, abdominal pain, and obstipation over 1 to 2 weeks1 suggest progression to complete obstruction.

IMAGING TESTS FOR MALIGNANT BOWEL OBSTRUCTION

What is the value of plain radiography?

Figure 1. Top, plain radiography shows dilated loops of small bowel (arrows) in the mid-abdominal region of a woman with a small-bowel obstruction from advanced ovarian cancer. Bottom, computed tomography in the same patient shows multiple, dilated loops of small bowel and air-fluid levels (arrows) in the anterior midline of the abdomen.
Plain radiography of the abdomen (kidney, ureter, bladder views) has only modest specificity and sensitivity in detecting bowel obstruction (Figure 1). In a patient who has symptoms of obstruction, overreliance on plain radiography can lead to false reassurances that there is no obstruction. The absence of air-fluid levels, dilated loops of bowel, or thickened bowel loops does not exclude malignant bowel obstruction. The overall accuracy of kidney, ureter, bladder radiography is reported to be as low as 50%, with more than 75% of plain films classified as nondiagnostic or not helpful.16,17

Despite these limitations, plain radiography is useful in assessing constipation and its severity as a potential cause of symptoms, and thus it remains an important initial imaging study in almost all patients with suspected malignant bowel obstruction.17,18 It is also used to assess response to treatment.

When do you need contrast radiographs?

Contrast radiography (barium swallow or barium or Gastrograffin enema) is helpful in patients with symptoms of dysmotility from suspected bowel obstruction. It defines the site or sites of obstruction and the extent of the obstruction with a fair degree of accuracy.7,19 Single-contrast studies, if positive, exclude opioid-induced bowel dysfunction or pseudo-obstruction in 83% of patients, with a sensitivity and specificity of 96% and 98%, respectively.8,20 Small-bowel follow-through with barium is more appropriate for low-grade obstructions or for symptomatic patients with a normal kidney, ureter, bladder radiograph.19

However, contrast radiography is limited by the patient’s ability to swallow barium or water-soluble contrast agents, and it can worsen nausea or vomiting.17,18 Also, barium is not absorbed systemically and may interfere with subsequent radiologic studies. Large volumes of contrast agents increase the risk of aspiration pneumonia in patients with poorly controlled nausea and can lead to severe impaction proximal to the obstructed site.8

 

 

Is enteroclysis better than barium swallow?

Enteroclysis, ie, injecting radiographic contrast into the bowel via a nasoduodenal tube, has some advantages over the barium swallow technique for detecting partial small-bowel obstruction, since it bypasses the stomach and allows for therapeutic decompression as well as direct visualization of the area of concern.17,18 Enteroclysis radiography objectively gauges severity of intestinal obstruction and bowel wall distensibility, which is an advantage over other imaging studies. Its sensitivity is 100% and specificity 88% in experienced hands.17 Enteroclysis studies also detect nonobstructing intraluminal tumors when computed tomography (CT) is not diagnostic.17,18,21

The drawbacks to enteroclysis are that it is technically difficult to perform and that few radiologists are trained in it.

When is CT useful?

CT is the primary imaging study for patients with obstructive symptoms and a history of abdominal malignancy or a palpable abdominal mass17,20,22,23 (Figure 1). It has a specificity of 100% and a sensitivity of 94%. It plays a major role in decision-making regarding surgery, endoscopy, or palliative interventions,7,19 as it locates the obstruction and differentiates benign from malignant causes with a fair degree of precision.22

CT findings in malignant bowel obstruction may include:

  • A mass at the site of obstruction or within the original surgical field
  • Lymphadenopathy
  • Abrupt transitions in luminal diameter or irregular thickening of the bowel wall at the site or sites of obstruction.7

SURGERY: A DIFFICULT DECISION

Is the patient fit for surgery?

Surgery for malignant bowel obstruction should not be done in patients who have advanced malignancies with bulky intra-abdominal metastases or cancer that has spread outside the abdominal cavity without taking into account treatment options for the cancer, the patient’s nutritional status, and the goals of care.

The role of abdominal surgery (debulking, resection, or bypass) in advanced cancer remains unclear and controversial.24 From 42% to 80% of patients report that symptoms improve after surgery, but recurrent obstruction occurs in 10% to 50%.10 Even in patients with low tumor bulk and good nutritional status, 30-day mortality rates range from 5% to 40%, and complication rates range from 9% to 90%.3,4,6,7,10,14

Outcomes after surgery depend on patient selection criteria perhaps as much as on the surgeon’s experience and skill. Patients with more advanced cancer who have had multiple surgical procedures and those with cancer that does not respond to chemotherapy and radiation present the greatest challenge to surgeons.23

What is the benefit of surgery?

Reports of palliative surgery have included information about 60-day survival rates after the operation, but a number of factors may be more meaningful in this context, such as postoperative symptoms, the patient’s overall wellbeing, how the original symptoms respond to the surgery, complications, and length of hospitalization.14 The paucity of published, validated, patient-related outcome data on which to gauge the value of surgery and the lack of a standard definition of “benefit” further confuse the objective determination of whether these patients benefit from surgery.

In a cohort with advanced ovarian cancer and bowel obstruction, surgery was detrimental to survival and quality of life for all subgroups, and most patients died in the hospital.6

The risk of surgery for malignant bowel obstruction is presumably higher than for abdominal surgery for other indications, since many of the patients are debilitated from their cancer and chemotherapy, and many are malnourished.23 Even when taking into account a potential selection bias in favor of surgery, several studies have reported no significant difference in 30-day mortality rates or median survival between operative and nonoperative groups.2,12 Neither the type of obstruction nor the extent of the surgery influenced outcomes. Surgical outcomes are best in patients with a benign cause of obstruction; little benefit is seen in operating on those with abdominal carcinomatosis.12

Nevertheless, surgery is beneficial in a select few. For patients with a good performance status, slowly progressive cancer, and an expected survival of more than 6 months, surgical bypass or resection is preferred.7,12,25 The challenge is to identify these surgical candidates, taking into account prognostic factors such as nutritional status, tumor burden, performance status, presence of ascites, advanced age, extensive prior chemotherapy or radiotherapy, and diffuse carcinomatosis.3,10,12,20,23

Is surgery consistent with the goals of care?

Crucial to decision-making are the goals of care. Since palliative surgery carries a low level of evidence for benefit in terms of quality of life and survival, time should be set aside to thoroughly review the patient’s medical condition, to explore options, and to clarify expectations and goals of care.3,10 Family members should be invited to be present during these discussions and to be involved in the decision-making process.

WHAT IS THE BENEFIT OF GASTRIC OR COLONIC STENTING?

Endoscopic procedures are alternatives to surgery and offer a palliative option in malignant bowel obstruction. Endoscopic procedures are associated with a shorter hospital stay and quicker recovery than after laparotomy.9,26–30 In certain situations, stenting serves as a bridge to surgery, allowing time to mitigate comorbid conditions, to enhance nutrition, and to complete staging, while relieving symptoms.27–29,31,32 Definitive surgery can be done as a single-stage procedure without a diverting enterostomy.

Self-expanding metal stents for gastric outlet, small-bowel, and colonic obstructions are an option in patients who have incurable metastatic disease who are unfit for surgery, in patients with a single point of obstruction or locally extensive disease, or in patients who do not want to undergo laparotomy.28–30

Technical and clinical success rates for colorectal stenting are high (88% to 93%).26,27 Stenting is more successful for left-sided colonic obstructions than for proximal colonic obstructions. Even for patients with extracolonic malignancies such as ovarian cancer, the technical success rate of colorectal stenting is 87%.26 However, patients with unrecognized peritoneal carcinomatosis or multifocal bowel obstruction are less likely to have symptomatic relief even after successful stenting.6,9

 

 

Contraindications to stenting

Absolute contraindications to stenting are colonic or tumor perforation with peritonitis. A relative contraindication is a rectal tumor within 2 cm of the anal margin. Stenting in this circumstance leads to tenesmus and incontinence.33

Complications of stenting

Death rates during colorectal stent insertion are less than 1%. The hospital stay and incidence of complications are significantly less than with surgery.26,30

Stent migration occurs in 10% of cases and is asymptomatic, but half of patients with this complication require a repeat intervention. The risk of migration is greater if chemotherapy or radiation therapy succeeds in shrinking the tumor.

Bleeding occurs in 5% of cases, usually from the underlying tumor.

Perforation occurs in 4%, but the rate increases to 10% with the use of dilatation before stent placement.

The rate of recurrent obstruction from tumor ingrowth, overgrowth, or fecal impaction is 10%.9,26,29 Recurrent obstruction may be treated with additional stents inserted within the original stent.9

GASTRIC OUTLET OBSTRUCTION: SURGERY VS STENTING

Gastrojejunostomy has in the past been the treatment of choice for gastric outlet obstruction. Certainly, patients with slow-growing tumors and an expected survival of greater than 60 days may be considered for this bypass procedure; those with a short tumor length, a single site of obstruction (preferably in the pylorus or proximal duodenum), a good performance status, and a life expectancy greater than 30 days are good candidates.7 Nevertheless, for patients with advanced cancer and poor performance status, gastroenterostomy carries a significant risk of morbidity and death.28

Endoscopic stenting of gastric outlet obstruction has a greater success rate, a shorter time to oral intake, a lower morbidity rate, a lower incidence of delayed gastric emptying, and a shorter hospital stay compared with gastroenterostomy.28,29 Technical success rates of stenting are 90%, and 75% of patients have resolution of nausea and vomiting.7 Stenting is generally not possible if the obstruction occurs beyond the ligament of Treitz.

Patients who are expected to survive less than 1 month or who have rapidly progressive disease, overt ascites, carcinomatosis, or multiple sites of obstruction should be managed with percutaneous, endoscopically placed gastrostomy tubes.7

Late complications of stenting for gastric outlet obstruction are occlusion with food or ingrowth of tumor through or around the wire mesh.7 This may require laser therapy or placement of a second stent, or both.

DRUG THERAPY

Medical therapy can palliate symptoms of malignant bowel obstruction for most patients.34 Recommendations have been published by the Working Group of the European Association for Palliative Care.24 Symptom management is focused on pain, nausea, and vomiting.

Which drugs can I use for abdominal pain?

Patients experience two types of abdominal pain: continuous and colic. Each type of pain requires different treatment approaches and classes of drugs.

Potent opioids such as morphine, hydromorphone (Dilaudid), and fentanyl (Fentora) are used to relieve continuous abdominal pain.7 The dose is titrated for adequate relief. Subcutaneous, intravenous, sublingual, and transdermal routes can be used if nausea and vomiting prevent oral administration.

However, opioids can aggravate colic by stimulating circular smooth muscle, leading to segmental contractions. Opioid-sparing adjuvant drugs such as ketorolac (Toradol) may improve colic and continuous pain and prevent a partial obstruction from becoming a complete obstruction by sparing opioid doses.35

Colic may persist or worsen with the use of opioids. Drugs that reduce colic include the scopolamine drugs hyoscine butylbromide and hyoscine hydrobromide, glycopyrrolate (Robinul), and octreotide (Sandostatin).7,34–37

Which drugs are appropriate for reducing nausea and vomiting?

Phenothiazines reduce nausea and control vomiting. Chlorpromazine (Thorazine), prochlorperazine (Compro, Compazine), and promethazine (Phenergan) have all been reported to treat nausea successfully.35,37

Haloperidol (Haldol), a butyrophenone selective dopamine D2-receptor antagonist, has negligible anticholinergic activity. At low doses it produces less sedation than phenothiazines and is an ideal agent for patients with nausea and delirium.35 Doses range from 5 to 15 mg/day, given in divided doses or as intermittent or continuous intravenous infusions.

Anticholinergics, with or without somatostatin analogues, reduce gastrointestinal secretions, fluid accumulation, and vomiting. Anticholinergics bind to muscarinic receptors on enteric neurons in the myenteric and the submucosal plexus. Dosages:

  • Hyoscine butylbromide 40 to 120 mg/day.
  • Hyoscine hydrobromide 0.2 to 0.9 mg/day.7,34

Glycopyrrolate, a quaternary ammonium anticholinergic, has minimal central nervous system penetration and is less likely to cause delirium or cardiac side effects compared with tertiary amine anticholinergics such as atropine and scopolamine.38 The recommended dose is 0.1 to 0.2 mg subcutaneously or intravenously three to four times daily.

Octreotide, an analogue of somatostatin, blocks the release of vasoactive intestinal polypeptide, which is increased in malignant bowel obstruction.14,15 It reduces the excretion of water, sodium, and chloride into the bowel lumen and increases the absorption of electrolytes and water. It also inhibits pancreatic enzyme secretion and splanchnic blood flow. The result of all these effects is reduced luminal content, reduced motility, reduced vascular congestion of the bowel wall, and, in certain circumstances, reduced ascites.39

In small randomized trials, octreotide was more successful than anticholinergics at improving nausea, vomiting, and colic in patients requiring a nasogastric tube and in those whose symptoms were refractory to standard medical treatment.5,34,40–43 A recent case report found octreotide helpful in resolving symptoms of partial bowel obstruction that were unresponsive to standard measures.44

Octreotide is well tolerated and reduces the time patients require a nasogastric tube without significantly worsening xerostomia. High cost limits its use in American hospice care due to the Medicare capitated system of reimbursement for drugs and services, and as a result it is a second-tier drug despite evidence of its efficacy.

Octreotide doses are 100 to 200 mg every 8 hours.

Metoclopramide (Reglan), a dopaminergic antagonist, a 5HT4 receptor agonist, and a 5HT3 receptor blocker at doses greater than 120 mg/day, combines the action of a phenothiazine, which blocks D2 receptors in the central chemoreceptor trigger zone, with promotility actions through serotonin receptors (5HT4).35,37

Metoclopramide should not be used with anticholinergics or in patients with colic or complete obstruction.35,45 In some centers it is the first-line drug for functional or partial bowel obstruction.7 Dosages range from 40 to 240 mg/day.

Olanzapine (Zyprexa), an atypical antipsychotic, blocks multiple neurotransmitter receptors (D2, H1, Ach, 5HT3) responsible for initiating emesis. It is an option in patients whose nausea and vomiting fail to respond to standard antiemetics.46 Dosages range from 2.5 to 20 mg/day.

Dissolvable tablets are given sublingually, which makes olanzapine a versatile antiemetic in cases of intractable nausea. Our unpublished experience is that the sublingual route reduces nausea associated with malignant bowel obstruction and obviates the need for subcutaneous injections or intravenous antiemetic infusions.

Corticosteroids. Although how corticosteroids relieve malignant bowel obstruction is unknown, they are presumed to act centrally.37,45 In addition, they reduce peritumoral edema and luminal salt and water, and they also have antiemetic and analgesic properties.

Evidence from a meta-analysis found that 6 to 16 mg of parenteral dexamethasone per day reduced symptoms and improved bowel function in 60% of patients but did not change the prognosis.11

A trial of 4 or 5 days is adequate to determine response. If there is no response, the corticosteroid should be rapidly tapered. Side effects are minimal when corticosteroids are used short-term.

Combination therapy. Only rarely does a single drug resolve symptoms of malignant bowel obstruction. Antiemetics, analgesics, corticosteroids, antisecretory anticholinergics, and octreotide are often required in combination to achieve acceptable symptom relief.3,5,7,47

In a small prospective case series, the combination of metoclopramide 60 mg/day, octreotide 0.3 mg/day, and dexamethasone 12 mg/day with a single bolus of amidotrizoic acid (a contrast agent) improved intestinal transit within 1 to 5 days and resolved vomiting within 24 hours.45

Compatibility and the route of administration of medications are key considerations when choosing drug combinations.

 

 

WHEN TO CONSIDER A VENTING GASTROSTOMY

Patients with a poor performance status, rapidly progressive disease, peritoneal carcinomatosis, a life expectancy of less than 30 days, or multiple levels of obstruction benefit from placement of a percutaneous endoscopic gastrostomy tube (ie, a venting gastrostomy) rather than surgery if symptoms do not respond to drug therapy.7,48 There is compelling evidence that this procedure relieves nausea and vomiting in 80% to 90% of patients and restores some level of oral intake in many.5,6,48,49 A venting gastrostomy tube can be placed during surgical exploration, percutaneously with fluoroscopy, or endoscopically.9

There are no absolute contraindications to gastrostomy tube placement. It is feasible even in patients with tumors encasing the stomach, diffuse carcinomatosis, and ascites.48 However, massive ascites, previous upper abdominal surgery, or a large mass attached to the abdominal wall make tube placement difficult.

Complications are often local. Patients experience transient abdominal wall pain after the procedure. Dislodgement, bleeding, catheter migration, peritonitis, and necrotizing fasciitis are early complications. Others include skin excoriation from leakage of gastric contents, leakage of ascitic fluid from the site, and obstruction or dislodgement of the tube.48,49

Patients can be discharged from the hospital soon after the tube is placed, usually with fewer medications than for patients who undergo surgery.48 This is particularly important for patients with a short expected survival. Some patients at home benefit from hydration (less than 2 L/day) via an existing central venous port or peripherally inserted central catheter, or by hypodermoclysis.

WHEN IS A NASOGASTRIC TUBE APPROPRIATE?

Some patients with malignant bowel obstruction require a nasogastric tube early in their hospital course.12 Unfortunately, nasogastric tubes, if left in place, cause nose and throat pain, sinusitis, abscess formation, erosion of nasal cartilage, aspiration, esophageal erosion, pharyngitis, and social isolation.5,6

Nasogastric tubes should be a temporizing measure to vent gastrointestinal secretions, reduce abdominal distension, and improve nausea and vomiting while a decision about surgery is being made.13,24 If surgery is not feasible, one can avoid the long-term complications and discomfort of a nasogastric tube via medical management and earlier evaluation for venting gastrostomy in those with symptoms that respond poorly to optimal medical management.49

WHICH PATIENTS BENEFIT FROM TOTAL PARENTERAL NUTRITION?

The use of total parenteral nutrition in patients with incurable malignancies is controversial. Enteral and parenteral feeding can increase muscle mass and improve functional status and quality of life in a subset of patients who are not suffering from cancer-related cachexia.2,50,51 However, for those whose weight loss and malnutrition are consequences of tumor-mediated cachexia, as demonstrated by anorexia and an elevated C-reactive protein level, parenteral nutrition is unlikely to improve the outcome.51 For most terminally ill patients, retrospective studies have failed to show that parenteral nutrition improves overall survival, performance status, or quality of life.2,48,50–54

Total parenteral nutrition poses risks: it is invasive and requires central venous access, which predisposes to infection; it requires frequent monitoring of hydration and electrolytes; and it predisposes to thrombosis, diarrhea, hyperglycemia, and liver failure.50–56

Total parenteral nutrition may be justified in patients with minimal tumor burden who are candidates for definitive surgery, or in those with a good performance status early in the disease course who have not had chemotherapy or whose cancer responds to chemotherapy.2,50–56

The American College of Physicians discourages the routine use of parenteral nutrition in those with advanced cancer who are undergoing palliative chemotherapy, since few patients benefit and many experience side effects.53

Total parenteral nutrition is much like a medical intervention in that it should be offered or continued only if it provides benefit. Conversations at the time that it is begun must include adverse effects that will lead to its discontinuation, and criteria for response. In certain situations, a limited trial of parenteral nutrition may be considered for patients with an uncertain prognosis or for those who have potentially reversible conditions that limit oral intake.51 In such cases, there should be a clear understanding between patient and physician that parenteral nutrition will be discontinued if it fails to show benefit.53

ADDITIONAL CONCERNS OF PATIENTS AND FAMILIES

‘Will I starve to death?’

Starvation is a fear echoed by patients and families. Ethical discourse on the continuation of nutrition and hydration for the terminally ill has been polarizing.57–60 Withdrawal of nutrition can be perceived as euthanasia.

Advanced cancer patients in general do not experience hunger, and those who do require only small amounts of food for satiation.61 In one report, most patients died of their advanced cancer and not from starvation.52 Artificial hydration and nutrition will thus not influence survival and can even be a burden without benefit in the imminently dying.60 These patients should be encouraged to take food orally for pleasure, as long as it is tolerated, without consideration of end points such as weight gain, body mass index, or albumin levels.

Complaints of thirst and dryness of the mouth are relieved with mouth care, ice chips, lubrication to the lips, and sips of fluid, rather than by parenteral nutrition.59 Patients with a terminal illness experience relief from thirst with minimal intake. The symptom of thirst may be relieved without hydration.34,61 Adequate hydration requires smaller fluid volumes due to decreased body weight, decreased renal clearance of free water, and decreased insensible water losses from reduced physical activity.58

‘Can we continue intravenous hydration so he won’t die of thirst?’

Overzealous intravenous hydration may worsen the symptoms of malignant bowel obstruction. Overhydration can increase secretions in the gut lumen and worsen the secretion-distention-contraction cycle, leading to greater abdominal pain and to nausea and vomiting.7 There is a greater risk of fluid overload in these patients, since they have edema and excessive interstitial fluid. Most have a low serum albumin level, which results in movement of fluid from intravascular to interstitial spaces due to reduced colloid osmotic pressure. In these instances, overzealous hydration can lead to respiratory insufficiency and worsening edema.

In spite of numerous discussions in the medical literature of the benefits and burdens of continual hydration, there is no consensus or guideline. When a patient has limited oral intake, the decision to hydrate should be individualized, with careful assessment of the risks and benefits and in accordance with the patient’s or family’s wishes.57,58

 

 

Is treatment at home feasible?

Discharging patients with inoperable malignant bowel obstruction requires careful planning. Patients and family members need to be educated on the use of around-the-clock medications and symptom-targeted, as-needed drugs. Days before discharge, questions about diet need to be clarified. Education about total parenteral nutrition and gastrostomy tube care should be completed before discharge from the hospital.

Drug management should be simplified, or compatible medications should be combined into a single infusion. For example, morphine, glycopyrrolate, and haloperidol or metoclopramide are chemically compatible in standard intravenous solutions and can be combined.

Families feel less anxious about the foreseen and the possible unforeseen course of the illness if they can talk with hospice workers early on. This early involvement also facilitates the transition to home hospice care.

SUMMARY OF IMPORTANT POINTS

  • Patients with malignant bowel obstruction need a highly individualized approach, tailored to their medical condition, the prognosis, and the goals of care.
  • Surgery should not be routinely undertaken; less-invasive approaches such as gastric or colonic stenting should be considered first.
  • Combinations of analgesics, antisecretory drugs, and antiemetics can provide acceptable symptom relief in the inoperable patient.
  • A venting gastrostomy should be considered if drug therapy fails to reduce nausea and vomiting to an acceptable level.
  • A nasogastric tube should be used only as a temporizing measure, until symptoms are controlled medically or a venting gastrostomy is placed.
  • Total parenteral nutrition is of benefit only in patients with intermediate life expectancy who may otherwise die of starvation rather than from the cancer itself.

Malignant bowel obstruction occurs in 5% to 51% of women with ovarian cancer and in 10% to 28% of patients with gastrointestinal cancer, predominantly in the advanced stages.1 Median survival after its onset ranges from 30 to 90 days.2–5

Its symptoms are challenging to manage, since nausea, vomiting, colic, and abdominal pain, which are common, cause significant physical distress and demoralization. The decision whether to correct it with surgery requires an individualized approach and a clear understanding of the goals of care and expected survival in the individual patient.

This review focuses on the management of inoperable malignant bowel obstruction and includes discussion of hydration, nutrition, and endoscopic palliative options.

WHAT ARE THE DIFFERENT TYPES OF OBSTRUCTION?

Bowel obstruction may be mechanical or functional, partial or complete, and may occur at one or at many sites. Tumors can impair bowel function in several ways6–8:

  • Intraluminal tumors can occlude the lumen or act as a point of intussusception.
  • Intramural tumors can extend to the mucosa and obstruct the lumen or impair peristalsis.
  • Mesenteric and omental masses or malignant adhesions can kink or angulate the bowel, creating an extramural obstruction.
  • Tumors that infiltrate into the mesentery, bowel muscle, or the enteric or celiac plexus can cause dysmotility.

Cholangiocarcinoma, pancreatic carcinoma, and gallbladder carcinoma are the most common tumors causing duodenal obstruction.9 Distal obstruction is caused mainly by colon and ovarian cancer.

Obstruction can be due to treatment

In a minority of patients, obstruction is unrelated to the cancer and is instead due to adhesions arising from surgery, radiation therapy (causing enteritis and strictures), desmoplastic reactions to intraperitoneal chemotherapy, torsion, or internal hernias.10–12

In rare cases, a patient has intestinal pseudo-obstruction from paraneoplastic destruction of enteric neurons, or severe ileus from anticholinergic or sympathomimetic drugs, as seen with acute colonic pseudo-obstruction (Ogilvie syndrome).13

Physiologic reactions to obstruction

Malignant bowel obstruction stimulates gastric, biliary, pancreatic, and intestinal secretions, decreases intraluminal sodium and water reabsorption, and increases mucosal sodium and water secretion.6,14 In response to the obstruction, peristalsis increases, and prostaglandin, vasoactive intestinal peptide, and nociceptive mediators are released. Vasoactive intestinal polypeptide perpetuates a cycle of secretion, distention, and contraction that leads to intestinal hyperemia, bowel edema, and accumulation of fluid in the lumen.8,10,11,15

Signs and symptoms depend on the site

The site of obstruction determines the signs and symptoms patients experience.7,14 Obstructions high in the gastrointestinal tract are associated with greater symptoms but fewer signs than colonic obstructions.1 Patients with proximal small-bowel obstruction have more severe nausea and a greater number of episodes of emesis, but they have relatively normal plain radiographs of the abdomen, which do not have the characteristic air-fluid levels commonly seen with distal small-bowel obstruction.

Most malignant obstructions remain partial, but increasing abdominal distention, worsening nausea, vomiting, abdominal pain, and obstipation over 1 to 2 weeks1 suggest progression to complete obstruction.

IMAGING TESTS FOR MALIGNANT BOWEL OBSTRUCTION

What is the value of plain radiography?

Figure 1. Top, plain radiography shows dilated loops of small bowel (arrows) in the mid-abdominal region of a woman with a small-bowel obstruction from advanced ovarian cancer. Bottom, computed tomography in the same patient shows multiple, dilated loops of small bowel and air-fluid levels (arrows) in the anterior midline of the abdomen.
Plain radiography of the abdomen (kidney, ureter, bladder views) has only modest specificity and sensitivity in detecting bowel obstruction (Figure 1). In a patient who has symptoms of obstruction, overreliance on plain radiography can lead to false reassurances that there is no obstruction. The absence of air-fluid levels, dilated loops of bowel, or thickened bowel loops does not exclude malignant bowel obstruction. The overall accuracy of kidney, ureter, bladder radiography is reported to be as low as 50%, with more than 75% of plain films classified as nondiagnostic or not helpful.16,17

Despite these limitations, plain radiography is useful in assessing constipation and its severity as a potential cause of symptoms, and thus it remains an important initial imaging study in almost all patients with suspected malignant bowel obstruction.17,18 It is also used to assess response to treatment.

When do you need contrast radiographs?

Contrast radiography (barium swallow or barium or Gastrograffin enema) is helpful in patients with symptoms of dysmotility from suspected bowel obstruction. It defines the site or sites of obstruction and the extent of the obstruction with a fair degree of accuracy.7,19 Single-contrast studies, if positive, exclude opioid-induced bowel dysfunction or pseudo-obstruction in 83% of patients, with a sensitivity and specificity of 96% and 98%, respectively.8,20 Small-bowel follow-through with barium is more appropriate for low-grade obstructions or for symptomatic patients with a normal kidney, ureter, bladder radiograph.19

However, contrast radiography is limited by the patient’s ability to swallow barium or water-soluble contrast agents, and it can worsen nausea or vomiting.17,18 Also, barium is not absorbed systemically and may interfere with subsequent radiologic studies. Large volumes of contrast agents increase the risk of aspiration pneumonia in patients with poorly controlled nausea and can lead to severe impaction proximal to the obstructed site.8

 

 

Is enteroclysis better than barium swallow?

Enteroclysis, ie, injecting radiographic contrast into the bowel via a nasoduodenal tube, has some advantages over the barium swallow technique for detecting partial small-bowel obstruction, since it bypasses the stomach and allows for therapeutic decompression as well as direct visualization of the area of concern.17,18 Enteroclysis radiography objectively gauges severity of intestinal obstruction and bowel wall distensibility, which is an advantage over other imaging studies. Its sensitivity is 100% and specificity 88% in experienced hands.17 Enteroclysis studies also detect nonobstructing intraluminal tumors when computed tomography (CT) is not diagnostic.17,18,21

The drawbacks to enteroclysis are that it is technically difficult to perform and that few radiologists are trained in it.

When is CT useful?

CT is the primary imaging study for patients with obstructive symptoms and a history of abdominal malignancy or a palpable abdominal mass17,20,22,23 (Figure 1). It has a specificity of 100% and a sensitivity of 94%. It plays a major role in decision-making regarding surgery, endoscopy, or palliative interventions,7,19 as it locates the obstruction and differentiates benign from malignant causes with a fair degree of precision.22

CT findings in malignant bowel obstruction may include:

  • A mass at the site of obstruction or within the original surgical field
  • Lymphadenopathy
  • Abrupt transitions in luminal diameter or irregular thickening of the bowel wall at the site or sites of obstruction.7

SURGERY: A DIFFICULT DECISION

Is the patient fit for surgery?

Surgery for malignant bowel obstruction should not be done in patients who have advanced malignancies with bulky intra-abdominal metastases or cancer that has spread outside the abdominal cavity without taking into account treatment options for the cancer, the patient’s nutritional status, and the goals of care.

The role of abdominal surgery (debulking, resection, or bypass) in advanced cancer remains unclear and controversial.24 From 42% to 80% of patients report that symptoms improve after surgery, but recurrent obstruction occurs in 10% to 50%.10 Even in patients with low tumor bulk and good nutritional status, 30-day mortality rates range from 5% to 40%, and complication rates range from 9% to 90%.3,4,6,7,10,14

Outcomes after surgery depend on patient selection criteria perhaps as much as on the surgeon’s experience and skill. Patients with more advanced cancer who have had multiple surgical procedures and those with cancer that does not respond to chemotherapy and radiation present the greatest challenge to surgeons.23

What is the benefit of surgery?

Reports of palliative surgery have included information about 60-day survival rates after the operation, but a number of factors may be more meaningful in this context, such as postoperative symptoms, the patient’s overall wellbeing, how the original symptoms respond to the surgery, complications, and length of hospitalization.14 The paucity of published, validated, patient-related outcome data on which to gauge the value of surgery and the lack of a standard definition of “benefit” further confuse the objective determination of whether these patients benefit from surgery.

In a cohort with advanced ovarian cancer and bowel obstruction, surgery was detrimental to survival and quality of life for all subgroups, and most patients died in the hospital.6

The risk of surgery for malignant bowel obstruction is presumably higher than for abdominal surgery for other indications, since many of the patients are debilitated from their cancer and chemotherapy, and many are malnourished.23 Even when taking into account a potential selection bias in favor of surgery, several studies have reported no significant difference in 30-day mortality rates or median survival between operative and nonoperative groups.2,12 Neither the type of obstruction nor the extent of the surgery influenced outcomes. Surgical outcomes are best in patients with a benign cause of obstruction; little benefit is seen in operating on those with abdominal carcinomatosis.12

Nevertheless, surgery is beneficial in a select few. For patients with a good performance status, slowly progressive cancer, and an expected survival of more than 6 months, surgical bypass or resection is preferred.7,12,25 The challenge is to identify these surgical candidates, taking into account prognostic factors such as nutritional status, tumor burden, performance status, presence of ascites, advanced age, extensive prior chemotherapy or radiotherapy, and diffuse carcinomatosis.3,10,12,20,23

Is surgery consistent with the goals of care?

Crucial to decision-making are the goals of care. Since palliative surgery carries a low level of evidence for benefit in terms of quality of life and survival, time should be set aside to thoroughly review the patient’s medical condition, to explore options, and to clarify expectations and goals of care.3,10 Family members should be invited to be present during these discussions and to be involved in the decision-making process.

WHAT IS THE BENEFIT OF GASTRIC OR COLONIC STENTING?

Endoscopic procedures are alternatives to surgery and offer a palliative option in malignant bowel obstruction. Endoscopic procedures are associated with a shorter hospital stay and quicker recovery than after laparotomy.9,26–30 In certain situations, stenting serves as a bridge to surgery, allowing time to mitigate comorbid conditions, to enhance nutrition, and to complete staging, while relieving symptoms.27–29,31,32 Definitive surgery can be done as a single-stage procedure without a diverting enterostomy.

Self-expanding metal stents for gastric outlet, small-bowel, and colonic obstructions are an option in patients who have incurable metastatic disease who are unfit for surgery, in patients with a single point of obstruction or locally extensive disease, or in patients who do not want to undergo laparotomy.28–30

Technical and clinical success rates for colorectal stenting are high (88% to 93%).26,27 Stenting is more successful for left-sided colonic obstructions than for proximal colonic obstructions. Even for patients with extracolonic malignancies such as ovarian cancer, the technical success rate of colorectal stenting is 87%.26 However, patients with unrecognized peritoneal carcinomatosis or multifocal bowel obstruction are less likely to have symptomatic relief even after successful stenting.6,9

 

 

Contraindications to stenting

Absolute contraindications to stenting are colonic or tumor perforation with peritonitis. A relative contraindication is a rectal tumor within 2 cm of the anal margin. Stenting in this circumstance leads to tenesmus and incontinence.33

Complications of stenting

Death rates during colorectal stent insertion are less than 1%. The hospital stay and incidence of complications are significantly less than with surgery.26,30

Stent migration occurs in 10% of cases and is asymptomatic, but half of patients with this complication require a repeat intervention. The risk of migration is greater if chemotherapy or radiation therapy succeeds in shrinking the tumor.

Bleeding occurs in 5% of cases, usually from the underlying tumor.

Perforation occurs in 4%, but the rate increases to 10% with the use of dilatation before stent placement.

The rate of recurrent obstruction from tumor ingrowth, overgrowth, or fecal impaction is 10%.9,26,29 Recurrent obstruction may be treated with additional stents inserted within the original stent.9

GASTRIC OUTLET OBSTRUCTION: SURGERY VS STENTING

Gastrojejunostomy has in the past been the treatment of choice for gastric outlet obstruction. Certainly, patients with slow-growing tumors and an expected survival of greater than 60 days may be considered for this bypass procedure; those with a short tumor length, a single site of obstruction (preferably in the pylorus or proximal duodenum), a good performance status, and a life expectancy greater than 30 days are good candidates.7 Nevertheless, for patients with advanced cancer and poor performance status, gastroenterostomy carries a significant risk of morbidity and death.28

Endoscopic stenting of gastric outlet obstruction has a greater success rate, a shorter time to oral intake, a lower morbidity rate, a lower incidence of delayed gastric emptying, and a shorter hospital stay compared with gastroenterostomy.28,29 Technical success rates of stenting are 90%, and 75% of patients have resolution of nausea and vomiting.7 Stenting is generally not possible if the obstruction occurs beyond the ligament of Treitz.

Patients who are expected to survive less than 1 month or who have rapidly progressive disease, overt ascites, carcinomatosis, or multiple sites of obstruction should be managed with percutaneous, endoscopically placed gastrostomy tubes.7

Late complications of stenting for gastric outlet obstruction are occlusion with food or ingrowth of tumor through or around the wire mesh.7 This may require laser therapy or placement of a second stent, or both.

DRUG THERAPY

Medical therapy can palliate symptoms of malignant bowel obstruction for most patients.34 Recommendations have been published by the Working Group of the European Association for Palliative Care.24 Symptom management is focused on pain, nausea, and vomiting.

Which drugs can I use for abdominal pain?

Patients experience two types of abdominal pain: continuous and colic. Each type of pain requires different treatment approaches and classes of drugs.

Potent opioids such as morphine, hydromorphone (Dilaudid), and fentanyl (Fentora) are used to relieve continuous abdominal pain.7 The dose is titrated for adequate relief. Subcutaneous, intravenous, sublingual, and transdermal routes can be used if nausea and vomiting prevent oral administration.

However, opioids can aggravate colic by stimulating circular smooth muscle, leading to segmental contractions. Opioid-sparing adjuvant drugs such as ketorolac (Toradol) may improve colic and continuous pain and prevent a partial obstruction from becoming a complete obstruction by sparing opioid doses.35

Colic may persist or worsen with the use of opioids. Drugs that reduce colic include the scopolamine drugs hyoscine butylbromide and hyoscine hydrobromide, glycopyrrolate (Robinul), and octreotide (Sandostatin).7,34–37

Which drugs are appropriate for reducing nausea and vomiting?

Phenothiazines reduce nausea and control vomiting. Chlorpromazine (Thorazine), prochlorperazine (Compro, Compazine), and promethazine (Phenergan) have all been reported to treat nausea successfully.35,37

Haloperidol (Haldol), a butyrophenone selective dopamine D2-receptor antagonist, has negligible anticholinergic activity. At low doses it produces less sedation than phenothiazines and is an ideal agent for patients with nausea and delirium.35 Doses range from 5 to 15 mg/day, given in divided doses or as intermittent or continuous intravenous infusions.

Anticholinergics, with or without somatostatin analogues, reduce gastrointestinal secretions, fluid accumulation, and vomiting. Anticholinergics bind to muscarinic receptors on enteric neurons in the myenteric and the submucosal plexus. Dosages:

  • Hyoscine butylbromide 40 to 120 mg/day.
  • Hyoscine hydrobromide 0.2 to 0.9 mg/day.7,34

Glycopyrrolate, a quaternary ammonium anticholinergic, has minimal central nervous system penetration and is less likely to cause delirium or cardiac side effects compared with tertiary amine anticholinergics such as atropine and scopolamine.38 The recommended dose is 0.1 to 0.2 mg subcutaneously or intravenously three to four times daily.

Octreotide, an analogue of somatostatin, blocks the release of vasoactive intestinal polypeptide, which is increased in malignant bowel obstruction.14,15 It reduces the excretion of water, sodium, and chloride into the bowel lumen and increases the absorption of electrolytes and water. It also inhibits pancreatic enzyme secretion and splanchnic blood flow. The result of all these effects is reduced luminal content, reduced motility, reduced vascular congestion of the bowel wall, and, in certain circumstances, reduced ascites.39

In small randomized trials, octreotide was more successful than anticholinergics at improving nausea, vomiting, and colic in patients requiring a nasogastric tube and in those whose symptoms were refractory to standard medical treatment.5,34,40–43 A recent case report found octreotide helpful in resolving symptoms of partial bowel obstruction that were unresponsive to standard measures.44

Octreotide is well tolerated and reduces the time patients require a nasogastric tube without significantly worsening xerostomia. High cost limits its use in American hospice care due to the Medicare capitated system of reimbursement for drugs and services, and as a result it is a second-tier drug despite evidence of its efficacy.

Octreotide doses are 100 to 200 mg every 8 hours.

Metoclopramide (Reglan), a dopaminergic antagonist, a 5HT4 receptor agonist, and a 5HT3 receptor blocker at doses greater than 120 mg/day, combines the action of a phenothiazine, which blocks D2 receptors in the central chemoreceptor trigger zone, with promotility actions through serotonin receptors (5HT4).35,37

Metoclopramide should not be used with anticholinergics or in patients with colic or complete obstruction.35,45 In some centers it is the first-line drug for functional or partial bowel obstruction.7 Dosages range from 40 to 240 mg/day.

Olanzapine (Zyprexa), an atypical antipsychotic, blocks multiple neurotransmitter receptors (D2, H1, Ach, 5HT3) responsible for initiating emesis. It is an option in patients whose nausea and vomiting fail to respond to standard antiemetics.46 Dosages range from 2.5 to 20 mg/day.

Dissolvable tablets are given sublingually, which makes olanzapine a versatile antiemetic in cases of intractable nausea. Our unpublished experience is that the sublingual route reduces nausea associated with malignant bowel obstruction and obviates the need for subcutaneous injections or intravenous antiemetic infusions.

Corticosteroids. Although how corticosteroids relieve malignant bowel obstruction is unknown, they are presumed to act centrally.37,45 In addition, they reduce peritumoral edema and luminal salt and water, and they also have antiemetic and analgesic properties.

Evidence from a meta-analysis found that 6 to 16 mg of parenteral dexamethasone per day reduced symptoms and improved bowel function in 60% of patients but did not change the prognosis.11

A trial of 4 or 5 days is adequate to determine response. If there is no response, the corticosteroid should be rapidly tapered. Side effects are minimal when corticosteroids are used short-term.

Combination therapy. Only rarely does a single drug resolve symptoms of malignant bowel obstruction. Antiemetics, analgesics, corticosteroids, antisecretory anticholinergics, and octreotide are often required in combination to achieve acceptable symptom relief.3,5,7,47

In a small prospective case series, the combination of metoclopramide 60 mg/day, octreotide 0.3 mg/day, and dexamethasone 12 mg/day with a single bolus of amidotrizoic acid (a contrast agent) improved intestinal transit within 1 to 5 days and resolved vomiting within 24 hours.45

Compatibility and the route of administration of medications are key considerations when choosing drug combinations.

 

 

WHEN TO CONSIDER A VENTING GASTROSTOMY

Patients with a poor performance status, rapidly progressive disease, peritoneal carcinomatosis, a life expectancy of less than 30 days, or multiple levels of obstruction benefit from placement of a percutaneous endoscopic gastrostomy tube (ie, a venting gastrostomy) rather than surgery if symptoms do not respond to drug therapy.7,48 There is compelling evidence that this procedure relieves nausea and vomiting in 80% to 90% of patients and restores some level of oral intake in many.5,6,48,49 A venting gastrostomy tube can be placed during surgical exploration, percutaneously with fluoroscopy, or endoscopically.9

There are no absolute contraindications to gastrostomy tube placement. It is feasible even in patients with tumors encasing the stomach, diffuse carcinomatosis, and ascites.48 However, massive ascites, previous upper abdominal surgery, or a large mass attached to the abdominal wall make tube placement difficult.

Complications are often local. Patients experience transient abdominal wall pain after the procedure. Dislodgement, bleeding, catheter migration, peritonitis, and necrotizing fasciitis are early complications. Others include skin excoriation from leakage of gastric contents, leakage of ascitic fluid from the site, and obstruction or dislodgement of the tube.48,49

Patients can be discharged from the hospital soon after the tube is placed, usually with fewer medications than for patients who undergo surgery.48 This is particularly important for patients with a short expected survival. Some patients at home benefit from hydration (less than 2 L/day) via an existing central venous port or peripherally inserted central catheter, or by hypodermoclysis.

WHEN IS A NASOGASTRIC TUBE APPROPRIATE?

Some patients with malignant bowel obstruction require a nasogastric tube early in their hospital course.12 Unfortunately, nasogastric tubes, if left in place, cause nose and throat pain, sinusitis, abscess formation, erosion of nasal cartilage, aspiration, esophageal erosion, pharyngitis, and social isolation.5,6

Nasogastric tubes should be a temporizing measure to vent gastrointestinal secretions, reduce abdominal distension, and improve nausea and vomiting while a decision about surgery is being made.13,24 If surgery is not feasible, one can avoid the long-term complications and discomfort of a nasogastric tube via medical management and earlier evaluation for venting gastrostomy in those with symptoms that respond poorly to optimal medical management.49

WHICH PATIENTS BENEFIT FROM TOTAL PARENTERAL NUTRITION?

The use of total parenteral nutrition in patients with incurable malignancies is controversial. Enteral and parenteral feeding can increase muscle mass and improve functional status and quality of life in a subset of patients who are not suffering from cancer-related cachexia.2,50,51 However, for those whose weight loss and malnutrition are consequences of tumor-mediated cachexia, as demonstrated by anorexia and an elevated C-reactive protein level, parenteral nutrition is unlikely to improve the outcome.51 For most terminally ill patients, retrospective studies have failed to show that parenteral nutrition improves overall survival, performance status, or quality of life.2,48,50–54

Total parenteral nutrition poses risks: it is invasive and requires central venous access, which predisposes to infection; it requires frequent monitoring of hydration and electrolytes; and it predisposes to thrombosis, diarrhea, hyperglycemia, and liver failure.50–56

Total parenteral nutrition may be justified in patients with minimal tumor burden who are candidates for definitive surgery, or in those with a good performance status early in the disease course who have not had chemotherapy or whose cancer responds to chemotherapy.2,50–56

The American College of Physicians discourages the routine use of parenteral nutrition in those with advanced cancer who are undergoing palliative chemotherapy, since few patients benefit and many experience side effects.53

Total parenteral nutrition is much like a medical intervention in that it should be offered or continued only if it provides benefit. Conversations at the time that it is begun must include adverse effects that will lead to its discontinuation, and criteria for response. In certain situations, a limited trial of parenteral nutrition may be considered for patients with an uncertain prognosis or for those who have potentially reversible conditions that limit oral intake.51 In such cases, there should be a clear understanding between patient and physician that parenteral nutrition will be discontinued if it fails to show benefit.53

ADDITIONAL CONCERNS OF PATIENTS AND FAMILIES

‘Will I starve to death?’

Starvation is a fear echoed by patients and families. Ethical discourse on the continuation of nutrition and hydration for the terminally ill has been polarizing.57–60 Withdrawal of nutrition can be perceived as euthanasia.

Advanced cancer patients in general do not experience hunger, and those who do require only small amounts of food for satiation.61 In one report, most patients died of their advanced cancer and not from starvation.52 Artificial hydration and nutrition will thus not influence survival and can even be a burden without benefit in the imminently dying.60 These patients should be encouraged to take food orally for pleasure, as long as it is tolerated, without consideration of end points such as weight gain, body mass index, or albumin levels.

Complaints of thirst and dryness of the mouth are relieved with mouth care, ice chips, lubrication to the lips, and sips of fluid, rather than by parenteral nutrition.59 Patients with a terminal illness experience relief from thirst with minimal intake. The symptom of thirst may be relieved without hydration.34,61 Adequate hydration requires smaller fluid volumes due to decreased body weight, decreased renal clearance of free water, and decreased insensible water losses from reduced physical activity.58

‘Can we continue intravenous hydration so he won’t die of thirst?’

Overzealous intravenous hydration may worsen the symptoms of malignant bowel obstruction. Overhydration can increase secretions in the gut lumen and worsen the secretion-distention-contraction cycle, leading to greater abdominal pain and to nausea and vomiting.7 There is a greater risk of fluid overload in these patients, since they have edema and excessive interstitial fluid. Most have a low serum albumin level, which results in movement of fluid from intravascular to interstitial spaces due to reduced colloid osmotic pressure. In these instances, overzealous hydration can lead to respiratory insufficiency and worsening edema.

In spite of numerous discussions in the medical literature of the benefits and burdens of continual hydration, there is no consensus or guideline. When a patient has limited oral intake, the decision to hydrate should be individualized, with careful assessment of the risks and benefits and in accordance with the patient’s or family’s wishes.57,58

 

 

Is treatment at home feasible?

Discharging patients with inoperable malignant bowel obstruction requires careful planning. Patients and family members need to be educated on the use of around-the-clock medications and symptom-targeted, as-needed drugs. Days before discharge, questions about diet need to be clarified. Education about total parenteral nutrition and gastrostomy tube care should be completed before discharge from the hospital.

Drug management should be simplified, or compatible medications should be combined into a single infusion. For example, morphine, glycopyrrolate, and haloperidol or metoclopramide are chemically compatible in standard intravenous solutions and can be combined.

Families feel less anxious about the foreseen and the possible unforeseen course of the illness if they can talk with hospice workers early on. This early involvement also facilitates the transition to home hospice care.

SUMMARY OF IMPORTANT POINTS

  • Patients with malignant bowel obstruction need a highly individualized approach, tailored to their medical condition, the prognosis, and the goals of care.
  • Surgery should not be routinely undertaken; less-invasive approaches such as gastric or colonic stenting should be considered first.
  • Combinations of analgesics, antisecretory drugs, and antiemetics can provide acceptable symptom relief in the inoperable patient.
  • A venting gastrostomy should be considered if drug therapy fails to reduce nausea and vomiting to an acceptable level.
  • A nasogastric tube should be used only as a temporizing measure, until symptoms are controlled medically or a venting gastrostomy is placed.
  • Total parenteral nutrition is of benefit only in patients with intermediate life expectancy who may otherwise die of starvation rather than from the cancer itself.

Malignant bowel obstruction occurs in 5% to 51% of women with ovarian cancer and in 10% to 28% of patients with gastrointestinal cancer, predominantly in the advanced stages.1 Median survival after its onset ranges from 30 to 90 days.2–5

Its symptoms are challenging to manage, since nausea, vomiting, colic, and abdominal pain, which are common, cause significant physical distress and demoralization. The decision whether to correct it with surgery requires an individualized approach and a clear understanding of the goals of care and expected survival in the individual patient.

This review focuses on the management of inoperable malignant bowel obstruction and includes discussion of hydration, nutrition, and endoscopic palliative options.

WHAT ARE THE DIFFERENT TYPES OF OBSTRUCTION?

Bowel obstruction may be mechanical or functional, partial or complete, and may occur at one or at many sites. Tumors can impair bowel function in several ways6–8:

  • Intraluminal tumors can occlude the lumen or act as a point of intussusception.
  • Intramural tumors can extend to the mucosa and obstruct the lumen or impair peristalsis.
  • Mesenteric and omental masses or malignant adhesions can kink or angulate the bowel, creating an extramural obstruction.
  • Tumors that infiltrate into the mesentery, bowel muscle, or the enteric or celiac plexus can cause dysmotility.

Cholangiocarcinoma, pancreatic carcinoma, and gallbladder carcinoma are the most common tumors causing duodenal obstruction.9 Distal obstruction is caused mainly by colon and ovarian cancer.

Obstruction can be due to treatment

In a minority of patients, obstruction is unrelated to the cancer and is instead due to adhesions arising from surgery, radiation therapy (causing enteritis and strictures), desmoplastic reactions to intraperitoneal chemotherapy, torsion, or internal hernias.10–12

In rare cases, a patient has intestinal pseudo-obstruction from paraneoplastic destruction of enteric neurons, or severe ileus from anticholinergic or sympathomimetic drugs, as seen with acute colonic pseudo-obstruction (Ogilvie syndrome).13

Physiologic reactions to obstruction

Malignant bowel obstruction stimulates gastric, biliary, pancreatic, and intestinal secretions, decreases intraluminal sodium and water reabsorption, and increases mucosal sodium and water secretion.6,14 In response to the obstruction, peristalsis increases, and prostaglandin, vasoactive intestinal peptide, and nociceptive mediators are released. Vasoactive intestinal polypeptide perpetuates a cycle of secretion, distention, and contraction that leads to intestinal hyperemia, bowel edema, and accumulation of fluid in the lumen.8,10,11,15

Signs and symptoms depend on the site

The site of obstruction determines the signs and symptoms patients experience.7,14 Obstructions high in the gastrointestinal tract are associated with greater symptoms but fewer signs than colonic obstructions.1 Patients with proximal small-bowel obstruction have more severe nausea and a greater number of episodes of emesis, but they have relatively normal plain radiographs of the abdomen, which do not have the characteristic air-fluid levels commonly seen with distal small-bowel obstruction.

Most malignant obstructions remain partial, but increasing abdominal distention, worsening nausea, vomiting, abdominal pain, and obstipation over 1 to 2 weeks1 suggest progression to complete obstruction.

IMAGING TESTS FOR MALIGNANT BOWEL OBSTRUCTION

What is the value of plain radiography?

Figure 1. Top, plain radiography shows dilated loops of small bowel (arrows) in the mid-abdominal region of a woman with a small-bowel obstruction from advanced ovarian cancer. Bottom, computed tomography in the same patient shows multiple, dilated loops of small bowel and air-fluid levels (arrows) in the anterior midline of the abdomen.
Plain radiography of the abdomen (kidney, ureter, bladder views) has only modest specificity and sensitivity in detecting bowel obstruction (Figure 1). In a patient who has symptoms of obstruction, overreliance on plain radiography can lead to false reassurances that there is no obstruction. The absence of air-fluid levels, dilated loops of bowel, or thickened bowel loops does not exclude malignant bowel obstruction. The overall accuracy of kidney, ureter, bladder radiography is reported to be as low as 50%, with more than 75% of plain films classified as nondiagnostic or not helpful.16,17

Despite these limitations, plain radiography is useful in assessing constipation and its severity as a potential cause of symptoms, and thus it remains an important initial imaging study in almost all patients with suspected malignant bowel obstruction.17,18 It is also used to assess response to treatment.

When do you need contrast radiographs?

Contrast radiography (barium swallow or barium or Gastrograffin enema) is helpful in patients with symptoms of dysmotility from suspected bowel obstruction. It defines the site or sites of obstruction and the extent of the obstruction with a fair degree of accuracy.7,19 Single-contrast studies, if positive, exclude opioid-induced bowel dysfunction or pseudo-obstruction in 83% of patients, with a sensitivity and specificity of 96% and 98%, respectively.8,20 Small-bowel follow-through with barium is more appropriate for low-grade obstructions or for symptomatic patients with a normal kidney, ureter, bladder radiograph.19

However, contrast radiography is limited by the patient’s ability to swallow barium or water-soluble contrast agents, and it can worsen nausea or vomiting.17,18 Also, barium is not absorbed systemically and may interfere with subsequent radiologic studies. Large volumes of contrast agents increase the risk of aspiration pneumonia in patients with poorly controlled nausea and can lead to severe impaction proximal to the obstructed site.8

 

 

Is enteroclysis better than barium swallow?

Enteroclysis, ie, injecting radiographic contrast into the bowel via a nasoduodenal tube, has some advantages over the barium swallow technique for detecting partial small-bowel obstruction, since it bypasses the stomach and allows for therapeutic decompression as well as direct visualization of the area of concern.17,18 Enteroclysis radiography objectively gauges severity of intestinal obstruction and bowel wall distensibility, which is an advantage over other imaging studies. Its sensitivity is 100% and specificity 88% in experienced hands.17 Enteroclysis studies also detect nonobstructing intraluminal tumors when computed tomography (CT) is not diagnostic.17,18,21

The drawbacks to enteroclysis are that it is technically difficult to perform and that few radiologists are trained in it.

When is CT useful?

CT is the primary imaging study for patients with obstructive symptoms and a history of abdominal malignancy or a palpable abdominal mass17,20,22,23 (Figure 1). It has a specificity of 100% and a sensitivity of 94%. It plays a major role in decision-making regarding surgery, endoscopy, or palliative interventions,7,19 as it locates the obstruction and differentiates benign from malignant causes with a fair degree of precision.22

CT findings in malignant bowel obstruction may include:

  • A mass at the site of obstruction or within the original surgical field
  • Lymphadenopathy
  • Abrupt transitions in luminal diameter or irregular thickening of the bowel wall at the site or sites of obstruction.7

SURGERY: A DIFFICULT DECISION

Is the patient fit for surgery?

Surgery for malignant bowel obstruction should not be done in patients who have advanced malignancies with bulky intra-abdominal metastases or cancer that has spread outside the abdominal cavity without taking into account treatment options for the cancer, the patient’s nutritional status, and the goals of care.

The role of abdominal surgery (debulking, resection, or bypass) in advanced cancer remains unclear and controversial.24 From 42% to 80% of patients report that symptoms improve after surgery, but recurrent obstruction occurs in 10% to 50%.10 Even in patients with low tumor bulk and good nutritional status, 30-day mortality rates range from 5% to 40%, and complication rates range from 9% to 90%.3,4,6,7,10,14

Outcomes after surgery depend on patient selection criteria perhaps as much as on the surgeon’s experience and skill. Patients with more advanced cancer who have had multiple surgical procedures and those with cancer that does not respond to chemotherapy and radiation present the greatest challenge to surgeons.23

What is the benefit of surgery?

Reports of palliative surgery have included information about 60-day survival rates after the operation, but a number of factors may be more meaningful in this context, such as postoperative symptoms, the patient’s overall wellbeing, how the original symptoms respond to the surgery, complications, and length of hospitalization.14 The paucity of published, validated, patient-related outcome data on which to gauge the value of surgery and the lack of a standard definition of “benefit” further confuse the objective determination of whether these patients benefit from surgery.

In a cohort with advanced ovarian cancer and bowel obstruction, surgery was detrimental to survival and quality of life for all subgroups, and most patients died in the hospital.6

The risk of surgery for malignant bowel obstruction is presumably higher than for abdominal surgery for other indications, since many of the patients are debilitated from their cancer and chemotherapy, and many are malnourished.23 Even when taking into account a potential selection bias in favor of surgery, several studies have reported no significant difference in 30-day mortality rates or median survival between operative and nonoperative groups.2,12 Neither the type of obstruction nor the extent of the surgery influenced outcomes. Surgical outcomes are best in patients with a benign cause of obstruction; little benefit is seen in operating on those with abdominal carcinomatosis.12

Nevertheless, surgery is beneficial in a select few. For patients with a good performance status, slowly progressive cancer, and an expected survival of more than 6 months, surgical bypass or resection is preferred.7,12,25 The challenge is to identify these surgical candidates, taking into account prognostic factors such as nutritional status, tumor burden, performance status, presence of ascites, advanced age, extensive prior chemotherapy or radiotherapy, and diffuse carcinomatosis.3,10,12,20,23

Is surgery consistent with the goals of care?

Crucial to decision-making are the goals of care. Since palliative surgery carries a low level of evidence for benefit in terms of quality of life and survival, time should be set aside to thoroughly review the patient’s medical condition, to explore options, and to clarify expectations and goals of care.3,10 Family members should be invited to be present during these discussions and to be involved in the decision-making process.

WHAT IS THE BENEFIT OF GASTRIC OR COLONIC STENTING?

Endoscopic procedures are alternatives to surgery and offer a palliative option in malignant bowel obstruction. Endoscopic procedures are associated with a shorter hospital stay and quicker recovery than after laparotomy.9,26–30 In certain situations, stenting serves as a bridge to surgery, allowing time to mitigate comorbid conditions, to enhance nutrition, and to complete staging, while relieving symptoms.27–29,31,32 Definitive surgery can be done as a single-stage procedure without a diverting enterostomy.

Self-expanding metal stents for gastric outlet, small-bowel, and colonic obstructions are an option in patients who have incurable metastatic disease who are unfit for surgery, in patients with a single point of obstruction or locally extensive disease, or in patients who do not want to undergo laparotomy.28–30

Technical and clinical success rates for colorectal stenting are high (88% to 93%).26,27 Stenting is more successful for left-sided colonic obstructions than for proximal colonic obstructions. Even for patients with extracolonic malignancies such as ovarian cancer, the technical success rate of colorectal stenting is 87%.26 However, patients with unrecognized peritoneal carcinomatosis or multifocal bowel obstruction are less likely to have symptomatic relief even after successful stenting.6,9

 

 

Contraindications to stenting

Absolute contraindications to stenting are colonic or tumor perforation with peritonitis. A relative contraindication is a rectal tumor within 2 cm of the anal margin. Stenting in this circumstance leads to tenesmus and incontinence.33

Complications of stenting

Death rates during colorectal stent insertion are less than 1%. The hospital stay and incidence of complications are significantly less than with surgery.26,30

Stent migration occurs in 10% of cases and is asymptomatic, but half of patients with this complication require a repeat intervention. The risk of migration is greater if chemotherapy or radiation therapy succeeds in shrinking the tumor.

Bleeding occurs in 5% of cases, usually from the underlying tumor.

Perforation occurs in 4%, but the rate increases to 10% with the use of dilatation before stent placement.

The rate of recurrent obstruction from tumor ingrowth, overgrowth, or fecal impaction is 10%.9,26,29 Recurrent obstruction may be treated with additional stents inserted within the original stent.9

GASTRIC OUTLET OBSTRUCTION: SURGERY VS STENTING

Gastrojejunostomy has in the past been the treatment of choice for gastric outlet obstruction. Certainly, patients with slow-growing tumors and an expected survival of greater than 60 days may be considered for this bypass procedure; those with a short tumor length, a single site of obstruction (preferably in the pylorus or proximal duodenum), a good performance status, and a life expectancy greater than 30 days are good candidates.7 Nevertheless, for patients with advanced cancer and poor performance status, gastroenterostomy carries a significant risk of morbidity and death.28

Endoscopic stenting of gastric outlet obstruction has a greater success rate, a shorter time to oral intake, a lower morbidity rate, a lower incidence of delayed gastric emptying, and a shorter hospital stay compared with gastroenterostomy.28,29 Technical success rates of stenting are 90%, and 75% of patients have resolution of nausea and vomiting.7 Stenting is generally not possible if the obstruction occurs beyond the ligament of Treitz.

Patients who are expected to survive less than 1 month or who have rapidly progressive disease, overt ascites, carcinomatosis, or multiple sites of obstruction should be managed with percutaneous, endoscopically placed gastrostomy tubes.7

Late complications of stenting for gastric outlet obstruction are occlusion with food or ingrowth of tumor through or around the wire mesh.7 This may require laser therapy or placement of a second stent, or both.

DRUG THERAPY

Medical therapy can palliate symptoms of malignant bowel obstruction for most patients.34 Recommendations have been published by the Working Group of the European Association for Palliative Care.24 Symptom management is focused on pain, nausea, and vomiting.

Which drugs can I use for abdominal pain?

Patients experience two types of abdominal pain: continuous and colic. Each type of pain requires different treatment approaches and classes of drugs.

Potent opioids such as morphine, hydromorphone (Dilaudid), and fentanyl (Fentora) are used to relieve continuous abdominal pain.7 The dose is titrated for adequate relief. Subcutaneous, intravenous, sublingual, and transdermal routes can be used if nausea and vomiting prevent oral administration.

However, opioids can aggravate colic by stimulating circular smooth muscle, leading to segmental contractions. Opioid-sparing adjuvant drugs such as ketorolac (Toradol) may improve colic and continuous pain and prevent a partial obstruction from becoming a complete obstruction by sparing opioid doses.35

Colic may persist or worsen with the use of opioids. Drugs that reduce colic include the scopolamine drugs hyoscine butylbromide and hyoscine hydrobromide, glycopyrrolate (Robinul), and octreotide (Sandostatin).7,34–37

Which drugs are appropriate for reducing nausea and vomiting?

Phenothiazines reduce nausea and control vomiting. Chlorpromazine (Thorazine), prochlorperazine (Compro, Compazine), and promethazine (Phenergan) have all been reported to treat nausea successfully.35,37

Haloperidol (Haldol), a butyrophenone selective dopamine D2-receptor antagonist, has negligible anticholinergic activity. At low doses it produces less sedation than phenothiazines and is an ideal agent for patients with nausea and delirium.35 Doses range from 5 to 15 mg/day, given in divided doses or as intermittent or continuous intravenous infusions.

Anticholinergics, with or without somatostatin analogues, reduce gastrointestinal secretions, fluid accumulation, and vomiting. Anticholinergics bind to muscarinic receptors on enteric neurons in the myenteric and the submucosal plexus. Dosages:

  • Hyoscine butylbromide 40 to 120 mg/day.
  • Hyoscine hydrobromide 0.2 to 0.9 mg/day.7,34

Glycopyrrolate, a quaternary ammonium anticholinergic, has minimal central nervous system penetration and is less likely to cause delirium or cardiac side effects compared with tertiary amine anticholinergics such as atropine and scopolamine.38 The recommended dose is 0.1 to 0.2 mg subcutaneously or intravenously three to four times daily.

Octreotide, an analogue of somatostatin, blocks the release of vasoactive intestinal polypeptide, which is increased in malignant bowel obstruction.14,15 It reduces the excretion of water, sodium, and chloride into the bowel lumen and increases the absorption of electrolytes and water. It also inhibits pancreatic enzyme secretion and splanchnic blood flow. The result of all these effects is reduced luminal content, reduced motility, reduced vascular congestion of the bowel wall, and, in certain circumstances, reduced ascites.39

In small randomized trials, octreotide was more successful than anticholinergics at improving nausea, vomiting, and colic in patients requiring a nasogastric tube and in those whose symptoms were refractory to standard medical treatment.5,34,40–43 A recent case report found octreotide helpful in resolving symptoms of partial bowel obstruction that were unresponsive to standard measures.44

Octreotide is well tolerated and reduces the time patients require a nasogastric tube without significantly worsening xerostomia. High cost limits its use in American hospice care due to the Medicare capitated system of reimbursement for drugs and services, and as a result it is a second-tier drug despite evidence of its efficacy.

Octreotide doses are 100 to 200 mg every 8 hours.

Metoclopramide (Reglan), a dopaminergic antagonist, a 5HT4 receptor agonist, and a 5HT3 receptor blocker at doses greater than 120 mg/day, combines the action of a phenothiazine, which blocks D2 receptors in the central chemoreceptor trigger zone, with promotility actions through serotonin receptors (5HT4).35,37

Metoclopramide should not be used with anticholinergics or in patients with colic or complete obstruction.35,45 In some centers it is the first-line drug for functional or partial bowel obstruction.7 Dosages range from 40 to 240 mg/day.

Olanzapine (Zyprexa), an atypical antipsychotic, blocks multiple neurotransmitter receptors (D2, H1, Ach, 5HT3) responsible for initiating emesis. It is an option in patients whose nausea and vomiting fail to respond to standard antiemetics.46 Dosages range from 2.5 to 20 mg/day.

Dissolvable tablets are given sublingually, which makes olanzapine a versatile antiemetic in cases of intractable nausea. Our unpublished experience is that the sublingual route reduces nausea associated with malignant bowel obstruction and obviates the need for subcutaneous injections or intravenous antiemetic infusions.

Corticosteroids. Although how corticosteroids relieve malignant bowel obstruction is unknown, they are presumed to act centrally.37,45 In addition, they reduce peritumoral edema and luminal salt and water, and they also have antiemetic and analgesic properties.

Evidence from a meta-analysis found that 6 to 16 mg of parenteral dexamethasone per day reduced symptoms and improved bowel function in 60% of patients but did not change the prognosis.11

A trial of 4 or 5 days is adequate to determine response. If there is no response, the corticosteroid should be rapidly tapered. Side effects are minimal when corticosteroids are used short-term.

Combination therapy. Only rarely does a single drug resolve symptoms of malignant bowel obstruction. Antiemetics, analgesics, corticosteroids, antisecretory anticholinergics, and octreotide are often required in combination to achieve acceptable symptom relief.3,5,7,47

In a small prospective case series, the combination of metoclopramide 60 mg/day, octreotide 0.3 mg/day, and dexamethasone 12 mg/day with a single bolus of amidotrizoic acid (a contrast agent) improved intestinal transit within 1 to 5 days and resolved vomiting within 24 hours.45

Compatibility and the route of administration of medications are key considerations when choosing drug combinations.

 

 

WHEN TO CONSIDER A VENTING GASTROSTOMY

Patients with a poor performance status, rapidly progressive disease, peritoneal carcinomatosis, a life expectancy of less than 30 days, or multiple levels of obstruction benefit from placement of a percutaneous endoscopic gastrostomy tube (ie, a venting gastrostomy) rather than surgery if symptoms do not respond to drug therapy.7,48 There is compelling evidence that this procedure relieves nausea and vomiting in 80% to 90% of patients and restores some level of oral intake in many.5,6,48,49 A venting gastrostomy tube can be placed during surgical exploration, percutaneously with fluoroscopy, or endoscopically.9

There are no absolute contraindications to gastrostomy tube placement. It is feasible even in patients with tumors encasing the stomach, diffuse carcinomatosis, and ascites.48 However, massive ascites, previous upper abdominal surgery, or a large mass attached to the abdominal wall make tube placement difficult.

Complications are often local. Patients experience transient abdominal wall pain after the procedure. Dislodgement, bleeding, catheter migration, peritonitis, and necrotizing fasciitis are early complications. Others include skin excoriation from leakage of gastric contents, leakage of ascitic fluid from the site, and obstruction or dislodgement of the tube.48,49

Patients can be discharged from the hospital soon after the tube is placed, usually with fewer medications than for patients who undergo surgery.48 This is particularly important for patients with a short expected survival. Some patients at home benefit from hydration (less than 2 L/day) via an existing central venous port or peripherally inserted central catheter, or by hypodermoclysis.

WHEN IS A NASOGASTRIC TUBE APPROPRIATE?

Some patients with malignant bowel obstruction require a nasogastric tube early in their hospital course.12 Unfortunately, nasogastric tubes, if left in place, cause nose and throat pain, sinusitis, abscess formation, erosion of nasal cartilage, aspiration, esophageal erosion, pharyngitis, and social isolation.5,6

Nasogastric tubes should be a temporizing measure to vent gastrointestinal secretions, reduce abdominal distension, and improve nausea and vomiting while a decision about surgery is being made.13,24 If surgery is not feasible, one can avoid the long-term complications and discomfort of a nasogastric tube via medical management and earlier evaluation for venting gastrostomy in those with symptoms that respond poorly to optimal medical management.49

WHICH PATIENTS BENEFIT FROM TOTAL PARENTERAL NUTRITION?

The use of total parenteral nutrition in patients with incurable malignancies is controversial. Enteral and parenteral feeding can increase muscle mass and improve functional status and quality of life in a subset of patients who are not suffering from cancer-related cachexia.2,50,51 However, for those whose weight loss and malnutrition are consequences of tumor-mediated cachexia, as demonstrated by anorexia and an elevated C-reactive protein level, parenteral nutrition is unlikely to improve the outcome.51 For most terminally ill patients, retrospective studies have failed to show that parenteral nutrition improves overall survival, performance status, or quality of life.2,48,50–54

Total parenteral nutrition poses risks: it is invasive and requires central venous access, which predisposes to infection; it requires frequent monitoring of hydration and electrolytes; and it predisposes to thrombosis, diarrhea, hyperglycemia, and liver failure.50–56

Total parenteral nutrition may be justified in patients with minimal tumor burden who are candidates for definitive surgery, or in those with a good performance status early in the disease course who have not had chemotherapy or whose cancer responds to chemotherapy.2,50–56

The American College of Physicians discourages the routine use of parenteral nutrition in those with advanced cancer who are undergoing palliative chemotherapy, since few patients benefit and many experience side effects.53

Total parenteral nutrition is much like a medical intervention in that it should be offered or continued only if it provides benefit. Conversations at the time that it is begun must include adverse effects that will lead to its discontinuation, and criteria for response. In certain situations, a limited trial of parenteral nutrition may be considered for patients with an uncertain prognosis or for those who have potentially reversible conditions that limit oral intake.51 In such cases, there should be a clear understanding between patient and physician that parenteral nutrition will be discontinued if it fails to show benefit.53

ADDITIONAL CONCERNS OF PATIENTS AND FAMILIES

‘Will I starve to death?’

Starvation is a fear echoed by patients and families. Ethical discourse on the continuation of nutrition and hydration for the terminally ill has been polarizing.57–60 Withdrawal of nutrition can be perceived as euthanasia.

Advanced cancer patients in general do not experience hunger, and those who do require only small amounts of food for satiation.61 In one report, most patients died of their advanced cancer and not from starvation.52 Artificial hydration and nutrition will thus not influence survival and can even be a burden without benefit in the imminently dying.60 These patients should be encouraged to take food orally for pleasure, as long as it is tolerated, without consideration of end points such as weight gain, body mass index, or albumin levels.

Complaints of thirst and dryness of the mouth are relieved with mouth care, ice chips, lubrication to the lips, and sips of fluid, rather than by parenteral nutrition.59 Patients with a terminal illness experience relief from thirst with minimal intake. The symptom of thirst may be relieved without hydration.34,61 Adequate hydration requires smaller fluid volumes due to decreased body weight, decreased renal clearance of free water, and decreased insensible water losses from reduced physical activity.58

‘Can we continue intravenous hydration so he won’t die of thirst?’

Overzealous intravenous hydration may worsen the symptoms of malignant bowel obstruction. Overhydration can increase secretions in the gut lumen and worsen the secretion-distention-contraction cycle, leading to greater abdominal pain and to nausea and vomiting.7 There is a greater risk of fluid overload in these patients, since they have edema and excessive interstitial fluid. Most have a low serum albumin level, which results in movement of fluid from intravascular to interstitial spaces due to reduced colloid osmotic pressure. In these instances, overzealous hydration can lead to respiratory insufficiency and worsening edema.

In spite of numerous discussions in the medical literature of the benefits and burdens of continual hydration, there is no consensus or guideline. When a patient has limited oral intake, the decision to hydrate should be individualized, with careful assessment of the risks and benefits and in accordance with the patient’s or family’s wishes.57,58

 

 

Is treatment at home feasible?

Discharging patients with inoperable malignant bowel obstruction requires careful planning. Patients and family members need to be educated on the use of around-the-clock medications and symptom-targeted, as-needed drugs. Days before discharge, questions about diet need to be clarified. Education about total parenteral nutrition and gastrostomy tube care should be completed before discharge from the hospital.

Drug management should be simplified, or compatible medications should be combined into a single infusion. For example, morphine, glycopyrrolate, and haloperidol or metoclopramide are chemically compatible in standard intravenous solutions and can be combined.

Families feel less anxious about the foreseen and the possible unforeseen course of the illness if they can talk with hospice workers early on. This early involvement also facilitates the transition to home hospice care.

SUMMARY OF IMPORTANT POINTS

  • Patients with malignant bowel obstruction need a highly individualized approach, tailored to their medical condition, the prognosis, and the goals of care.
  • Surgery should not be routinely undertaken; less-invasive approaches such as gastric or colonic stenting should be considered first.
  • Combinations of analgesics, antisecretory drugs, and antiemetics can provide acceptable symptom relief in the inoperable patient.
  • A venting gastrostomy should be considered if drug therapy fails to reduce nausea and vomiting to an acceptable level.
  • A nasogastric tube should be used only as a temporizing measure, until symptoms are controlled medically or a venting gastrostomy is placed.
  • Total parenteral nutrition is of benefit only in patients with intermediate life expectancy who may otherwise die of starvation rather than from the cancer itself.

KEY POINTS

  • Combinations of analgesics, antisecretory drugs, and antiemetics can provide acceptable symptom relief.
  • A venting gastrostomy should be considered if drug therapy fails to reduce nausea and vomiting to an acceptable level.
  • A nasogastric tube should be used only as a temporizing measure, until symptoms are controlled medically or a venting gastrostomy is placed.
  • Total parenteral nutrition is beneficial only in patients with intermediate life expectancy who may otherwise die of starvation rather than the cancer itself.

Hospitalist Laments Level of Palliative Care

Bradley Flansbaum, DO, MPH, SFHM, director of the hospitalist program at Lenox Hill Hospital in New York City, recently posted "A Hospitalist's Lament," on the SHM-sponsored The Hospitalist Leader blog about the nuances of palliative care and advanced-care-planning discussions for patients nearing the end of life.

Dr. Flansbaum writes that, when asked to name a medical specialty other than HM that he might have enjoyed pursuing, he replies: "pain and palliative care." As he explains, "I didn’t discover that this was an area of interest for me until my career was much advanced," too late to pursue new opportunities for advanced training in palliative-care fellowships.

Yet he views eliciting the needs and wishes of terminally ill hospitalized patients as an art worth mastering. Hospitalists inevitably deal with end-of-life issues as a routine part of their jobs. "It's in our bailiwick. It's what we do, and it behooves us to get better at it," he says.

In his post, Dr. Flansbaum examines the recent medical literature (Sudore RL, Fried TR. Ann Int Med 2010;153:256; Perkins HS. Ann Int Med 2007;147:51-57; Sulmasy DP, Snyder L. JAMA 2010;304:1946-1947) questioning the benefits of advanced-care planning and advance-directive documents, such as living wills, in shaping the care patients want and need at the end of their lives. While these documents are not wasted effort, he says, "too often they're not very useful. We're learning that it's an incredibly dynamic process, contingent on cultural factors, and changing over time. One piece of paper with a static declaration isn't going to cover the bases. I've come to realize that it is about a talking, ongoing process."

Part of his "lament" as a hospitalist is that caring for terminally ill patients can be rife with ambiguities. Meanwhile, "everybody talks about how there's so much money wasted at the end of life, and we should be corralling our healthcare resources in a more efficient way. And yet the solutions we will need to get us to that place are damned hard," he says. (Listen to excerpts from the interview with Dr. Flansbaum [MP3 12.8MB])

Dr. Flansbaum recommends hospitalists make detailed conversations with patients confronting life-limiting illnesses a priority, which requires setting aside enough time for patients and understanding that such conversations are not singular events. He also encourages physicians to consider what their own values and priorities might be in such a situation, an exercise he recently conducted with his residents.

Nonopioid Agents for Pain Management Being Studied

SAN DIEGO – Pain management alternatives to opioids continue to evolve, according to Joseph F. Dasta, M.Sc. (Pharm.).

Dr. Joseph F. Dasta    

New options include intravenous ibuprofen, approved in June 2009; nasal ketorolac, approved in May 2010; and intravenous acetaminophen, approved in November 2010.

Nonopioid alternatives are needed because data "suggest that opioids as well as untreated pain are associated with development of postoperative delirium," said Mr. Dasta, a health care consultant who is also a faculty member at the College of Pharmacy at the University of Texas, Austin.

Most of the available agents for pain management are short acting, "which can be good and bad," Mr. Dasta said at the annual congress of the Society of Critical Care Medicine. In addition, many of the currently approved agents for pain management require intravenous administration and may cause adverse drug reactions.

Intravenous diclofenac is currently being investigated as another possible therapy, Mr. Dasta said, as are the cyclo-oxygenase-2 selective inhibitors etoricoxib and parecoxib, and the nonsteroidal anti-inflammatory drug lornoxicam.

New studies of bupivacaine, an anesthetic drug that lasts for 6-10 hours, are also underway. "Several formulations are being developed whereby bupivacaine would be instilled into the surgical site, to the operative area, and last for several days," Mr. Dasta said. "Hopefully, we’ll see some of this technology come to market."

New guidelines from the Society of Critical Care Medicine on sedation analgesia and delirium are expected to be released later in 2011, Mr. Dasta said. Topics covered related to pain will include behavioral and physiologic measures of pain, procedural and nonprocedural pain, and the role of opioids, NMDA-receptor antagonists, and other nonopioids.

Mr. Dasta disclosed that he is a paid consultant for Cadence, Hospira, and Pacira Pharmaceuticals.

Study Challenges Notion of Pressure Ulcers as a 'Never Event'

SAN DIEGO – The development of hospital-acquired pressure ulcers may be unavoidable in patients who present with respiratory and hemodynamic medical problems that impede optimal oxygenation to tissues, results from a study of more than 800 patients showed.

Margaret Mullen-Fortino    

The findings challenge the position of the Centers for Medicaid and Medicare Services that pressure ulcers in this setting are a so-called "never event," Margaret Mullen-Fortino, R.N., said at the annual congress of the Society of Critical Care Medicine.

"They are categorized as a never event because it’s believed that these are reasonably preventable through the application of evidence-based guidelines," said Ms. Mullen-Fortino, operations director of the surgical/trauma ICU at the Hospital of the University of Pennsylvania, Philadelphia. "The evidence-based guidelines include the acronym SKIN, with the S standing for surface selection such as low-air-pressure mattresses. The K stands for keep turning patients, the I stands for incontinence management, and the N stands for nutrition – making sure that patients are adequately nourished with enough protein."

However, she continued, "There is a large population of practitioners who believe that pressure ulcers are not a never event, that there are comorbidities that increase the chances of patients developing pressure ulcers. Much like a patient experiences a myocardial infarction because blood does not get to the heart muscle, we believe that pressure ulcers develop because adequate blood supply does not get to the skin, which is the largest organ in the body. Our hypothesis is that there is an association between the severity of illness and the development of pressure ulcers."

To test this hypothesis, Ms. Mullen-Fortino and her associates conducted a prospective cohort study of 824 patients who were admitted to the 20-bed surgical/trauma ICU at the Hospital of the University of Pennsylvania and to the 20-bed medical ICU at the Christ Hospital, Cincinnati, between Dec. 15, 2009, and Dec. 12, 2010. Variables assessed included age, length of stay, APACHE score, Braden score, readmission, and use of mechanical ventilation and vasopressors.

Ms. Mullen-Fortino reported that of the 824 patients studied, 221 (26.8%) developed pressure ulcers. Of these patients, 144 (65.1%) were ventilated and 67 (30.3%) required vasopressor support.

Among the entire study population, the median APACHE score was 74, with a range of 26-153. The median length of stay was 2 days, with a range of 1-91 days; the median Braden score was 14, with a range of 7-20; and the median patient age was 63 years.

All of the variables studied had a statistically significant association with the development of pressure ulcers with the exception of the use of vasopressors, "which was a surprise," Ms. Mullen-Fortino said.

She and her associates then performed logistic regression analysis that was limited to ICU length of stay, APACHE score, use of mechanical ventilation, and use of vasopressors. The Braden score was excluded "because that’s a predictive model for skin integrity, not really for severity of illness," she explained. In this analysis, only use of mechanical ventilation and vasopressors were significantly associated with the development of pressure ulcers (odds ratios of 4.55 and 2.17, respectively).

Next, the researchers intend to prospectively examine the cohort using the Sequential Organ Failure Assessment, which quantifies the severity of the patient’s illness based on the degree of organ dysfunction serially over time, "as opposed to the APACHE score, which provides you severity of illness on admission," Ms. Mullen-Fortino said. "We’re hoping to see if the progression of the severity of illness correlates with the development of pressure ulcers. The compilation of this evidence will hopefully serve to inform future policy."

In 2007, she said, more than 250,000 hospitalized patients were reported to have stage 3 and 4 pressure ulcers. The cost of treatment is about $43,000 per pressure ulcer, and the condition demands "a tremendous amount of nursing resources and time," she said.

Ms. Mullen-Fortino said that she had no relevant financial conflicts to disclose.

Body

This is one of the first well-conducted, observational studies that would suggest that in some severely ill individuals, host factors outweigh any approach taken for the prevention of pressure ulcers in hospitalized patients.

On a larger scale, the findings suggest that the use of the hospital-acquired conditions list by the Centers for Medicare & Medicaid Services is putting the cart before the horse. The simple reality is that you can do everything right to prevent pressure ulcers and yet they still will occur in some patients.

Of course, we have observational evidence that with really good nursing care and the use of preventive devices before the skin begins to break down, you can indeed prevent ulcers. But even with those interventions, you're never going to prevent all of them. Expecting a 100% prevention rate is misguided.

We simply do not have an infinite amount of resources to deploy in the prevention of this so-called "never event". And even if we did have infinite resources, reimbursement would still be docked when pressure ulcers inevitably developed in the most severely ill patients.

There are other examples of this disparity between CMS's expectations and the evidence regarding outcomes. Despite randomized controlled trial data showing that even with the very best care a certain percentage of patients discharged after hip or knee arthroplasty will be readmitted within 30 days for venous thromboembolism, hospitals are penalized when the unavoidable occurs.

It would appear that in these circumstances, the government is cutting its costs under the guise of quality. And they are penalizing providers even when the highest quality of care is given.

Body

This is one of the first well-conducted, observational studies that would suggest that in some severely ill individuals, host factors outweigh any approach taken for the prevention of pressure ulcers in hospitalized patients.

On a larger scale, the findings suggest that the use of the hospital-acquired conditions list by the Centers for Medicare & Medicaid Services is putting the cart before the horse. The simple reality is that you can do everything right to prevent pressure ulcers and yet they still will occur in some patients.

Of course, we have observational evidence that with really good nursing care and the use of preventive devices before the skin begins to break down, you can indeed prevent ulcers. But even with those interventions, you're never going to prevent all of them. Expecting a 100% prevention rate is misguided.

We simply do not have an infinite amount of resources to deploy in the prevention of this so-called "never event". And even if we did have infinite resources, reimbursement would still be docked when pressure ulcers inevitably developed in the most severely ill patients.

There are other examples of this disparity between CMS's expectations and the evidence regarding outcomes. Despite randomized controlled trial data showing that even with the very best care a certain percentage of patients discharged after hip or knee arthroplasty will be readmitted within 30 days for venous thromboembolism, hospitals are penalized when the unavoidable occurs.

It would appear that in these circumstances, the government is cutting its costs under the guise of quality. And they are penalizing providers even when the highest quality of care is given.

Pay Held Hostage to the Unattainable
Pay Held Hostage to the Unattainable

SAN DIEGO – The development of hospital-acquired pressure ulcers may be unavoidable in patients who present with respiratory and hemodynamic medical problems that impede optimal oxygenation to tissues, results from a study of more than 800 patients showed.

The findings challenge the position of the Centers for Medicaid and Medicare Services that pressure ulcers in this setting are a so-called "never event," Margaret Mullen-Fortino, R.N., said at the annual congress of the Society of Critical Care Medicine.

"They are categorized as a never event because it’s believed that these are reasonably preventable through the application of evidence-based guidelines," said Ms. Mullen-Fortino, operations director of the surgical/trauma ICU at the Hospital of the University of Pennsylvania, Philadelphia. "The evidence-based guidelines include the acronym SKIN, with the S standing for surface selection such as low-air-pressure mattresses. The K stands for keep turning patients, the I stands for incontinence management, and the N stands for nutrition – making sure that patients are adequately nourished with enough protein."

However, she continued, "There is a large population of practitioners who believe that pressure ulcers are not a never event, that there are comorbidities that increase the chances of patients developing pressure ulcers. Much like a patient experiences a myocardial infarction because blood does not get to the heart muscle, we believe that pressure ulcers develop because adequate blood supply does not get to the skin, which is the largest organ in the body. Our hypothesis is that there is an association between the severity of illness and the development of pressure ulcers."

To test this hypothesis, Ms. Mullen-Fortino and her associates conducted a prospective cohort study of 824 patients who were admitted to the 20-bed surgical/trauma ICU at the Hospital of the University of Pennsylvania and to the 20-bed medical ICU at the Christ Hospital, Cincinnati, between Dec. 15, 2009, and Dec. 12, 2010. Variables assessed included age, length of stay, APACHE score, Braden score, readmission, and use of mechanical ventilation and vasopressors.

Ms. Mullen-Fortino reported that of the 824 patients studied, 221 (26.8%) developed pressure ulcers. Of these patients, 144 (65.1%) were ventilated and 67 (30.3%) required vasopressor support.

Among the entire study population, the median APACHE score was 74, with a range of 26-153. The median length of stay was 2 days, with a range of 1-91 days; the median Braden score was 14, with a range of 7-20; and the median patient age was 63 years.

All of the variables studied had a statistically significant association with the development of pressure ulcers with the exception of the use of vasopressors, "which was a surprise," Ms. Mullen-Fortino said.

She and her associates then performed logistic regression analysis that was limited to ICU length of stay, APACHE score, use of mechanical ventilation, and use of vasopressors. The Braden score was excluded "because that’s a predictive model for skin integrity, not really for severity of illness," she explained. In this analysis, only use of mechanical ventilation and vasopressors were significantly associated with the development of pressure ulcers (odds ratios of 4.55 and 2.17, respectively).

Next, the researchers intend to prospectively examine the cohort using the Sequential Organ Failure Assessment, which quantifies the severity of the patient’s illness based on the degree of organ dysfunction serially over time, "as opposed to the APACHE score, which provides you severity of illness on admission," Ms. Mullen-Fortino said. "We’re hoping to see if the progression of the severity of illness correlates with the development of pressure ulcers. The compilation of this evidence will hopefully serve to inform future policy."

In 2007, she said, more than 250,000 hospitalized patients were reported to have stage 3 and 4 pressure ulcers. The cost of treatment is about $43,000 per pressure ulcer, and the condition demands "a tremendous amount of nursing resources and time," she said.

Ms. Mullen-Fortino said that she had no relevant financial conflicts to disclose.

Fentanyl Transmucosal Tablets Approved for Breakthrough Cancer Pain

The Food and Drug Administration’s approval of immediate-release Abstral (fentanyl) transmucosal tablets provides a new option for managing breakthrough pain for adults with cancer.

Approved on Jan. 7, the drug is indicated for the management of breakthrough pain in patients aged 18 years and older with cancer, who already use around-the-clock opioid pain medication and who need and are able to safely use high doses of an additional opioid medicine.

Breakthrough pain is defined as pain that comes on suddenly for short periods of time and is not alleviated by a patient’s usual pain management plan. These patients should be considered opioid tolerant because of their current opioid medication use, according to a news release from the agency.

Immediate-release transmucosal medications, such as Abstral, are administered on the soft surfaces of the mouth, the nasal passages or throat where they dissolve and are absorbed.

The approval comes with the condition that the drug only be made available through through a Risk Evaluation and Mitigation Strategy (REMS) program, in order to minimize the risk of misuse, abuse, addiction, and overdose. Fentanyl is a schedule II opioid under the Controlled Substances Act.

The program requires pharmacies, distributors, and health care professionals who prescribe to outpatients to enroll in the program in order to prescribe, dispense, and distribute this product.

Common adverse reactions include nausea, constipation, drowsiness, and headache. Serious adverse events, including deaths, have been reported in patients with other immediate-release transmucosal fentanyl products, according to the FDA. The deaths occurred as a result of improper patient selection and/or improper dosing.

Health care professionals are encouraged to report adverse side effects or medication errors from the use of this drug to the FDA’s MedWatch Adverse Event Reporting program or by calling 800-332-1088.
