Some 80,000 active-duty women are stationed in states with abortion restrictions or bans. That’s 40% of active-duty service women in the continental United States, according to research sponsored by the US Department of Defense (DoD) and released in September. Nearly all (95%) are of reproductive age. Annually, an estimated 2573 to 4126 women have an abortion, but just a handful of those are done at military treatment facilities. Moreover, roughly 275,000 DoD civilians also live in states with a full ban or extreme restrictions on access to abortion. Of those, more than 81,000 are women. Nearly 43% have no access to abortion or drastically abridged access.  

The recent Supreme Court ruling in Dobbs v Jackson Women’s Health Organization has created uncertainty for those women and their families, and potential legal and financial risk for the health care practitioners who would provide reproductive care, Defense Secretary Lloyd Austin said in an October 20, 2022 memo.

Therefore, he has directed the DoD to take “all appropriate action… as soon as possible to ensure that our service members and their families can access reproductive health care and our health care providers can operate effectively.”

Among the actions he has approved: Paying for travel to reproductive health care—essentially, making it more feasible for members to cross state lines. Service members, he noted in the memo, are often required to travel or move to meet staffing, operational, and training requirements. The “practical effects,” he said, are that significant numbers of service members and their families “may be forced to travel greater distances, take more time off from work, and pay more out-of-pocket expenses to receive reproductive health care.” 

Those effects, Austin said, “qualify as unusual, extraordinary, hardship, or emergency circumstances for service members and their dependents and will interfere with our ability to recruit, retain, and maintain the readiness of a highly qualified force.”

Women, who comprise 17% of the active-duty force, are the fastest-growing subpopulation in the military. For the past several years, according to the DoD research report, the military services have been “deliberately recruiting women”—who perform essential duties in every sector: health care and electrical and mechanical equipment repair, for example.

“The full effects of Dobbs on military readiness are yet to be known,” the report says, but it notes several potential problems: Women may not join the service knowing that they could end up in a state with restrictions. If already serving, they may leave. In some states, women face criminal prosecution.

The long arm of Dobbs reaches far into the future, too. For instance, if unintended pregnancies are carried to term, the DoD will need to provide care to women during pregnancy, delivery, and the postpartum period—and the family will need to care for the child. Looking only at women in states with restricted access or bans, the DoD estimates the number of unintended pregnancies annually would be 2800 among civilian employees and between 4400 and 4700 among active-duty service women.

Men are also directly affected: More than 40% of male service members are married to a civilian woman who is a TRICARE dependent, 20% of active-duty service women are married to a fellow service member, and active-duty service men might be responsible for pregnancies among women who are not DoD dependents but who might be unable to get an abortion, the DoD report notes.

Austin has directed the DoD to create a uniform policy that allows for appropriate administrative absence, to establish travel and transportation allowances, and to amend any applicable travel regulations to facilitate official travel to access noncovered reproductive health care that is unavailable within the local area of the service member’s permanent duty station.

So that health care practitioners do not have to face criminal or civil liability or risk losing their licenses, Austin directed the DoD to develop a program to reimburse applicable fees, as appropriate and consistent with applicable federal law, for DoD health care practitioners who wish to become licensed in a state other than that in which they are currently licensed. He also directed the DoD to develop a program to support DoD practitioners who are subject to adverse action, including indemnification of any verdict, judgment, or other monetary award consistent with applicable law.

“Our greatest strength is our people,” Austin wrote. “There is no higher priority than taking care of our people, and ensuring their health and well-being.” He directed that the actions outlined in the memorandum “be executed as soon as possible.”

In an intensive push to fill acute workforce shortages, the US Department of Veterans Affairs (VA) is holding a “national onboarding surge event” the week of November 14. The goal is to get people who have already said yes to a job in the VA on that job more quickly. Every VA facility has been asked to submit a list of the highest-priority candidates, regardless of the position.

One of the most pressing reasons for getting more workers into the pipeline faster is that more and more veterans are entering VA care. As of October 1, tens of thousands of veterans will be eligible for VA health care, thanks to the Sergeant First Class Heath Robinson Honoring our Promise to Address Comprehensive Toxics Act of 2022 (PACT Act), passed in August, which expanded benefits for post-9/11 service members with illnesses due to toxic exposures.

Another reason is the need to fill the gaps left by attrition. In an October 19 press briefing, VA Undersecretary for Health Shereef Elnahal said the agency needs to hire about 52,000 employees per year just to keep up with the rate of health care professionals (HCPs) leaving the agency. At a September breakfast meeting with the Defense Writers Group, VA Secretary Denis McDonough said July 2022 marked the first month this year that the VA hired more nurses than it lost to retirement. He said the VA needs to hire 45,000 nurses over the next 3 years to keep up with attrition and growing demand for veteran care.

“We have to do a better job on hiring,” McDonough said. Streamlining the process is a major goal. Hiring rules loosened during the pandemic have since tightened back up. He pointed out that in many cases, the VA takes 90 to 100 days to onboard candidates and called the long-drawn-out process “being dragged through a bureaucratic morass.” During that time, he said, “They’re not being paid, they’re filling out paperwork… That’s disastrous.” In his press briefing, Elnahal said “we lose folks after we’ve made the selection” because the process is so long.

Moreover, the agency has a critical shortage not only of HCPs but the human resources professionals needed to fast-track the hirees’ progress. McDonough called it a “supply chain issue.” “We have the lowest ratio of human resource professionals per employee in the federal government by a long shot.” Partly, he said, because “a lot of our people end up hired away to other federal agencies.”

McDonough said the VA is also interested in transitioning more active-duty service members with in-demand skills, certifications, and talent into the VA workforce. “Cross-walking active duty into VA service much more aggressively,” he said, is another way to “grow that supply of ready, deployable, trained personnel.” The PACT Act gives the VA new incentives to entice workers, such as expanded recruitment, retention bonuses, and student loan repayment. The VA already provides training to about 1500 nurse and nurse residency programs across the VA, McDonough said but has plans for expanding to 5 times its current scope. He also addressed the question of a looming physician shortage: “Roughly 7 in 10 doctors in the United States will have had some portion of their training in a VA facility. We have to maintain that training function going forward.” The VA trains doctors, he added, “better than anybody else.”

The onboarding event will serve as a “national signal that we take this priority very seriously,” Elnahal said. “This will be not only a chance to have a step function improvement in the number of folks on board, which is an urgent priority, but to also set the groundwork for the more longitudinal work that we will need to do to improve the hiring process.”

Bulking up the workforce, he said, is “still far and away among our first priorities. Because if we don’t get our hospitals and facility staffed, it’s going to be a really hard effort to make process on the other priorities.”

A commonly prescribed direct oral anticoagulant (DOAC) has the lowest risk of bleeding, say researchers. Used to prevent strokes in those with atrial fibrillation (AFib), DOACs have recently become more common than warfarin, the previous standard treatment, as they do not require as much follow-up monitoring – which was “particularly valuable” during the COVID-19 pandemic – and have “less risk” of side effects, highlighted the authors of a new study, published in Annals of Internal Medicine.

However, the authors explained that, although current guidelines recommend using DOACs over warfarin in patients with AFib, “head-to-head trial data do not exist to guide the choice of DOAC.” So, they set out to try and fill this evidence gap by doing a large-scale comparison between all DOACs – apixaban, dabigatran, edoxaban, and rivaroxaban – in routine clinical practice.

Wallis Lau, PhD, University College London, and co–lead author, said: “Direct oral anticoagulants have been prescribed with increasing frequency worldwide in recent years, but evidence comparing them directly has been limited.”
 

One drug stood out

For the multinational population-based cohort study the researchers compared the efficacy and risk of side effects for the four most common DOACs. They reviewed data – from five standardized electronic health care databases that covered 221 million people in the United Kingdom, France, Germany, and the United States – of 527,226 patients who had been newly diagnosed with AFib between 2010 and 2019, and who had received a new DOAC prescription. The study included 281,320 apixaban users, 61,008 dabigatran users, 12,722 edoxaban users, and 172,176 rivaroxaban users.

Database-specific hazard ratios of ischemic stroke or systemic embolism, intracranial hemorrhage, gastrointestinal bleeding, and all-cause mortality between DOACs were estimated using a Cox regression model stratified by propensity score and pooled using a random-effects model.

In total, 9,530 ischemic stroke or systemic embolism events, 841 intercranial hemorrhage events, 8,319 gastrointestinal bleeding events, and 1,476 deaths were identified over the study follow-up. The researchers found that all four drugs were comparable on outcomes for ischemic stroke, intercranial hemorrhage, and all-cause mortality.

However, they identified a difference in the risk of gastrointestinal bleeding, which they highlighted “is one of the most common and concerning side effects of DOACs.”

“Apixaban stood out as having lower risk of gastrointestinal bleeding,” said the authors, with a 19%-28% lower risk when compared directly with each of the other three DOACs. Specifically, apixaban use was associated with lower risk for gastrointestinal bleeding than use of dabigatran (HR, 0.81; 95% confidence interval, 0.70-0.94), edoxaban (HR, 0.77; 95% CI, 0.66-0.91), or rivaroxaban (HR, 0.72; 95% CI, 0.66-0.79).

The researchers also highlighted that their findings held true when looking at data only from those aged over 80, and those with chronic kidney disease, two groups that are “often underrepresented” in clinical trials.
 

Apixaban may be preferable

The researchers concluded that, among patients with AFib, apixaban use was associated with lower risk for gastrointestinal bleeding and similar rates of ischemic stroke or systemic embolism, intracranial hemorrhage and all-cause mortality, compared with dabigatran, edoxaban, and rivaroxaban.

“Our results indicate that apixaban may be preferable to other blood thinners because of the lower rate of gastrointestinal bleeding and similar rates of stroke, a finding that we hope will be supported by randomized controlled trials,” said Dr. Lau.

However, he emphasized that, “as with all medications, potential risks and benefits can differ between people, so considering the full spectrum of outcomes and side effects will still be necessary for each individual patient.”

The authors all declared no conflicting interests.

“Apixaban stood out as having lower risk of gastrointestinal bleeding,” said the authors, with a 19%-28% lower risk when compared directly with each of the other three DOACs. Specifically, apixaban use was associated with lower risk for gastrointestinal bleeding than use of dabigatran (HR, 0.81; 95% confidence interval, 0.70-0.94), edoxaban (HR, 0.77; 95% CI, 0.66-0.91), or rivaroxaban (HR, 0.72; 95% CI, 0.66-0.79).

The researchers also highlighted that their findings held true when looking at data only from those aged over 80, and those with chronic kidney disease, two groups that are “often underrepresented” in clinical trials.
 

Apixaban may be preferable

The researchers concluded that, among patients with AFib, apixaban use was associated with lower risk for gastrointestinal bleeding and similar rates of ischemic stroke or systemic embolism, intracranial hemorrhage and all-cause mortality, compared with dabigatran, edoxaban, and rivaroxaban.

“Our results indicate that apixaban may be preferable to other blood thinners because of the lower rate of gastrointestinal bleeding and similar rates of stroke, a finding that we hope will be supported by randomized controlled trials,” said Dr. Lau.

However, he emphasized that, “as with all medications, potential risks and benefits can differ between people, so considering the full spectrum of outcomes and side effects will still be necessary for each individual patient.”

The authors all declared no conflicting interests.

For those affected, recurrent urinary tract infections (UTIs) are sometimes stressful. However, even an informative discussion about risk factors and the imparting of behavioral recommendations can be very helpful for many women. Antibiotic prophylaxis should only be considered once all nonantibiotic therapy options have been exhausted.

One in seven women suffers at least once a year from cystitis. Around a third of those women develop a further urinary tract infection 6-12 months after the first infection. A urinary tract infection is classified as recurrent if two symptomatic episodes have occurred within the last 6 months or if three episodes have occurred within the last 12 months.

There are many different approaches to reducing the recurrence rate of urinary tract infections, Daniel Klussmann and Florian Wagenlehner, MD, of the department and outpatient clinic for urology at the University of Giessen (Germany) wrote in DMW Klinischer Fortschritt. Aside from general information and advice, nonantibiotic therapy options are particularly important for recurrence reduction, with the aim of preventing the development of resistance and the corresponding adverse effects of antibiotics.
 

Fluids and D-mannose

An individual consultation discussion is the most important nonantibiotic strategy. Studies have shown that this strategy alone can lower the frequency of recurrent UTIs. According to the authors, special education programs on the causes and behavioral measures are especially helpful. Included in these programs is the recommendation to drink a sufficient, but not excessive, amount of fluids: approximately 1.5 liters per day. In one randomized study, this level of consumption halved UTI frequency. However, drinking an excessive amount of fluids should also be avoided, otherwise the antimicrobial peptides present in the urine become overly diluted.

The regular consumption of fruit juice, especially of that from berries, is also beneficial, according to the authors. However, study results on long-term prevention using cranberry products are inconsistent, and they are not recommended in the updated guideline. Like cranberries, D-mannose also inhibits the fimbriae of the Escherichia coli bacteria and therefore the bacteria’s ability to bind to the bladder epithelium. The authors cite a study in which, following the intake of 2 g of D-mannose dissolved in a glass of water every day, the rate of urinary tract infections dropped significantly, compared with consumption of placebo.

Additional recommendations in the S3 guideline include various phytotherapeutic products such as bearberry leaves, nasturtium herb, or horseradish root, although studies on the comparability of phytotherapeutic agents are very difficult to execute, the authors conceded.

It is already known that there is a positive correlation (by a factor of 60) between the recurrence rate of UTIs and the frequency of sexual intercourse. Even with contraceptive methods (such as vaginal suppositories, diaphragms or condoms coated with spermicide, and intrauterine devices), the risk of urinary tract infections increases by a factor of 2-14. Sexual abstinence, even if temporary, can be a remedy. Evidence for the recommendation to urinate immediately after coitus is contradictory in the literature, however. Excessive intimate hygiene clearly damages the local protective environment.
 

Estrogen substitution beneficial

For postmenopausal women, there is also the option of local estriol substitution (0.5 mg/day) as another nonantibiotic method of prophylaxis. This treatment serves as therapy for vaginal atrophy and reduces both vaginal colonization with uropathogens and the vaginal pH level. The authors cite Scandinavian studies that detected no increase in the risk of breast cancer from the local application of estriol.

Furthermore, the current guidelines recommend oral immunostimulation with bacterial cell wall components from uropathogenic strains of E. coli (OM-89, Uro-Vaxom). The authors reported on two meta-studies in which the average recurrence rate was reduced by 39%, compared with placebo. In addition, the treatment time for breakthrough infections decreased significantly, and prevention with OM-89 could even be started during acute therapy. Also recommended is parenteral immunostimulation with inactivated pathogens (StroVac). Acupuncture as cutaneous immunostimulation has also displayed a positive protective effect.

Only when nonantibiotic therapy fails and the patient is under a high amount of psychological strain should antibiotic prophylaxis be initiated, according to the authors. A period of 3-6 months should be the target here. When choosing an antibiotic and before starting therapy, the corresponding pathogen should be confirmed through a urine culture, and resistance testing should be performed. On the other hand, single-use, postcoital antibiotic prevention could be an alternative, particularly for women in whom a correlation between recurrent UTIs and sexual intercourse has been suspected, the authors wrote.

For devout Muslims, praying multiple times a day is a lifelong observance and a core aspect of their faith. But osteoarthritis of the knee (KOA) can make kneeling and prostration challenging. To address this problem in an aging U.S. Muslim population, a multicenter team developed literature-based guidelines published online in Arthritis & Rheumatology.

In an interview, corresponding author Mahfujul Z. Haque, a medical student at Michigan State University, Grand Rapids, discussed the guide, which he assembled with Marina N. Magrey, MD, the Ronald Moskowitz Professor of Rheumatology at Case Western Reserve University, Cleveland, and orthopedic surgeon Karl C. Roberts, MD, president of West Michigan Orthopaedics in Grand Rapids, among others.

Could you detail the clinical and cultural context for these recommendations?

Mr. Haque: Muslims currently make up 1.1% of the U.S. population, or 3.45 million people. This guidance provides advice to Muslim patients with KOA in a culturally sensitive manner that can supplement standard care. Prayer, or Salah, is a religious obligation typically performed in 17-48 daily repetitions of squatting, floor sitting, full-knee flexion, and kneeling. For patients with KOA, prayer can be painful, and a few studies have found a link between these repeated movements and KOA progression.

Yet recommending stopping or limiting prayer is insensitive, so our group did a thorough literature search to identify easily implemented and culturally appropriate ways to ease praying.

Is there a traditional preference for praying on a hard surface?

Mr. Haque: Prayer can be performed on any surface that is clean and free from impurities. Cushioned and carpeted surfaces are permissible if the surface is somewhat firm and supportive for when worshippers prostrate themselves and put their faces on the ground. For example, compacted snow that wouldn’t allow the face to sink into it is permissible, but snow that is soft and would allow the face to sink in is not.

Have an increasing number of older patients raised the issue of knee pain during prayers?

Mr. Haque: We found no research on this in the literature. Anecdotally, however, two of our authors lead prayer in large Muslim communities in Detroit, and people often share with them that they feel discomfort during prayer and ask if there is anything they can do to limit this.

It is important to dispel the common myth that after total knee replacement one cannot kneel. About 20% of patients have some anterior knee discomfort after total knee arthroplasty, which can be exacerbated by kneeling, but kneeling causes no harm and can be done safely.

Could you outline the main recommendations?

Mr. Haque: These fall under three main categories: prayer surface, mechanics, and lifestyle modifications. The surface recommendations essentially advise using prayer rugs that provide cushioning or using cushioned kneepads.

The mechanics recommendations involve bracing with the palms down, standing up using the hands and knees, and guiding prayer motions with the hands. Chairs may be used as well.

Lifestyle recommendations outline home-exercise programs tailored to KOA and suggest the use of ice and compression during acute exacerbations.

Could these recommendations benefit other arthritic joints such as the wrists?

Mr. Haque: Anecdotally, our authors do not hear about pain in joints except for the knee and spine. To a limited extent, some of these recommendations may help patients with spinal arthritis as well.

What do you see as the greatest obstacle to implementation?

Mr. Haque: These recommendations, although permissible in the Muslim faith, are not part of traditional ritual and thus patients may simply forget to implement them. We advise physicians to ask patients which recommendations they are most likely to follow and to monitor how these have worked for them.

What is your best overall advice for broaching this issue with patients?

Mr. Haque: Holistic, functional, and culturally sensitive recommendations will be highly appreciated. Physicians are therefore encouraged to share this guidance with Muslim patients while using terms such as Salah, pronounced saa-laah, and Sajdah, pronounced sajduh and meaning prostration, and engage in a healthy dialogue.

These guidelines received no funding. The authors disclosed no competing interests relevant to their recommendations, but Dr. Magrey reported consulting and research relationships with private-sector companies outside of this work.

Dementia and mild cognitive impairment (MCI) disproportionately affect Black and Hispanic individuals, as well as people with less education, based on new U.S. data from The Health and Retirement Study (HRS).

These inequities likely stem from structural racism and income inequality, necessitating a multifaceted response at an institutional level, according to lead author Jennifer J. Manly, PhD, a professor of neuropsychology in neurology at the Gertrude H. Sergievsky Center and the Taub Institute for Research in Aging and Alzheimer’s Disease at Columbia University, New York.
 

A more representative dataset

Between 2001 and 2003, a subset of HRS participants underwent extensive neuropsychological assessment in the Aging, Demographics, and Memory Study (ADAMS), providing data which have since been cited by hundreds of published studies, the investigators wrote in JAMA Neurology. Those data, however, failed to accurately represent the U.S. population at the time, and have not been updated since.

“The ADAMS substudy was small, and the limited inclusion of Black, Hispanic, and American Indian or Alaska Native participants contributed to lack of precision of estimates among minoritized racial and ethnic groups that have been shown to experience a higher burden of cognitive impairment and dementia,” Dr. Manly and colleagues wrote.

The present analysis used a more representative dataset from HRS participants who were 65 years or older in 2016. From June 2016 to October 2017, 3,496 of these individuals underwent comprehensive neuropsychological test battery and informant interview, with dementia and MCI classified based on standard diagnostic criteria.

In total, 393 people were classified with dementia (10%), while 804 had MCI (22%), both of which approximate estimates reported by previous studies, according to the investigators. In further alignment with past research, age was a clear risk factor; each 5-year increment added 17% and 95% increased risk of MCI and dementia, respectively.

Compared with college-educated participants, individuals who did not graduate from high school had a 60% increased risk for both dementia (odds ratio, 1.6; 95% confidence interval, 1.1-2.3) and MCI (OR, 1.6; 95% CI, 1.2-2.2). Other educational strata were not associated with significant differences in risk.

Compared with White participants, Black individuals had an 80% increased risk of dementia (OR, 1.8; 95% CI, 1.2-2.7), but no increased risk of MCI. Conversely, non-White Hispanic individuals had a 40% increased risk of MCI (OR, 1.4; 95% CI, 1.0-2.0), but no increased risk of dementia, compared with White participants.

“Older adults racialized as Black and Hispanic are more likely to develop cognitive impairment and dementia because of historical and current structural racism and income inequality that restrict access to brain-health benefits and increase exposure to harm,” Dr. Manly said in a written comment.

These inequities deserve a comprehensive response, she added.

“Actions and policies that decrease discriminatory and aggressive policing policies, invest in schools that serve children that are racialized as Black and Hispanic, repair housing and economic inequalities, and provide equitable access to mental and physical health, can help to narrow disparities in later life cognitive impairment,” Dr. Manly said. “Two other areas of focus for policy makers are the shortage in the workforce of dementia care specialists, and paid family leave for caregiving.”
 

Acknowledging the needs of the historically underrepresented

Lealani Mae Acosta, MD, MPH, associate professor of neurology at Vanderbilt University Medical Center, Nashville, Tenn., applauded the investigators for their “conscious effort to expand representation of historically underrepresented minorities.”

The findings themselves support what has been previously reported, Dr. Acosta said in an interview, including the disproportionate burden of cognitive disorders among people of color and those with less education.

Clinicians need to recognize that certain patient groups face increased risks of cognitive disorders, and should be screened accordingly, Dr. Acosta said, noting that all aging patients should undergo such screening. The push for screening should also occur on a community level, along with efforts to build trust between at-risk populations and health care providers.

While Dr. Acosta reiterated the importance of these new data from Black and Hispanic individuals, she noted that gaps in representation remain, and methods of characterizing populations deserve refinement.

“I’m a little bit biased because I’m an Asian physician,” Dr. Acosta said. “As much as I’m glad that they’re highlighting these different disparities, there weren’t enough [participants in] specific subgroups like American Indian or Alaska Native, Asian, Native Hawaiian or Pacific Islander, to be able to identify specific trends within [those groups] that are, again, historically underrepresented patient populations.”

Grouping all people of Asian descent may also be an oversimplification, she added, as differences may exist between individuals originating from different countries.

“We always have to be careful about lumping certain groups together in analyses,” Dr. Acosta said. “That’s just another reminder to us – as clinicians, as researchers – that we need to do better by our patients by expanding research opportunities, and really studying these historically underrepresented populations.”

The study was supported by the National Institute on Aging. The investigators disclosed additional relationships with the Alzheimer’s Association and the National Institutes of Health. Dr. Acosta reported no relevant competing interests.

Conversely, non-White Hispanic individuals had a 40% increased risk of MCI (OR, 1.4; 95% CI, 1.0-2.0), but no increased risk of dementia, compared with White participants.

“Older adults racialized as Black and Hispanic are more likely to develop cognitive impairment and dementia because of historical and current structural racism and income inequality that restrict access to brain-health benefits and increase exposure to harm,” Dr. Manly said in a written comment.

These inequities deserve a comprehensive response, she added.

“Actions and policies that decrease discriminatory and aggressive policing policies, invest in schools that serve children that are racialized as Black and Hispanic, repair housing and economic inequalities, and provide equitable access to mental and physical health, can help to narrow disparities in later life cognitive impairment,” Dr. Manly said. “Two other areas of focus for policy makers are the shortage in the workforce of dementia care specialists, and paid family leave for caregiving.”
 

Acknowledging the needs of the historically underrepresented

Lealani Mae Acosta, MD, MPH, associate professor of neurology at Vanderbilt University Medical Center, Nashville, Tenn., applauded the investigators for their “conscious effort to expand representation of historically underrepresented minorities.”

The findings themselves support what has been previously reported, Dr. Acosta said in an interview, including the disproportionate burden of cognitive disorders among people of color and those with less education.

Clinicians need to recognize that certain patient groups face increased risks of cognitive disorders, and should be screened accordingly, Dr. Acosta said, noting that all aging patients should undergo such screening. The push for screening should also occur on a community level, along with efforts to build trust between at-risk populations and health care providers.

While Dr. Acosta reiterated the importance of these new data from Black and Hispanic individuals, she noted that gaps in representation remain, and methods of characterizing populations deserve refinement.

“I’m a little bit biased because I’m an Asian physician,” Dr. Acosta said. “As much as I’m glad that they’re highlighting these different disparities, there weren’t enough [participants in] specific subgroups like American Indian or Alaska Native, Asian, Native Hawaiian or Pacific Islander, to be able to identify specific trends within [those groups] that are, again, historically underrepresented patient populations.”

Grouping all people of Asian descent may also be an oversimplification, she added, as differences may exist between individuals originating from different countries.

“We always have to be careful about lumping certain groups together in analyses,” Dr. Acosta said. “That’s just another reminder to us – as clinicians, as researchers – that we need to do better by our patients by expanding research opportunities, and really studying these historically underrepresented populations.”

The study was supported by the National Institute on Aging. The investigators disclosed additional relationships with the Alzheimer’s Association and the National Institutes of Health. Dr. Acosta reported no relevant competing interests.

Dementia and mild cognitive impairment (MCI) disproportionately affect Black and Hispanic individuals, as well as people with less education, based on new U.S. data from The Health and Retirement Study (HRS).

These inequities likely stem from structural racism and income inequality, necessitating a multifaceted response at an institutional level, according to lead author Jennifer J. Manly, PhD, a professor of neuropsychology in neurology at the Gertrude H. Sergievsky Center and the Taub Institute for Research in Aging and Alzheimer’s Disease at Columbia University, New York.
 

A more representative dataset

Between 2001 and 2003, a subset of HRS participants underwent extensive neuropsychological assessment in the Aging, Demographics, and Memory Study (ADAMS), providing data which have since been cited by hundreds of published studies, the investigators wrote in JAMA Neurology. Those data, however, failed to accurately represent the U.S. population at the time, and have not been updated since.

“The ADAMS substudy was small, and the limited inclusion of Black, Hispanic, and American Indian or Alaska Native participants contributed to lack of precision of estimates among minoritized racial and ethnic groups that have been shown to experience a higher burden of cognitive impairment and dementia,” Dr. Manly and colleagues wrote.

The present analysis used a more representative dataset from HRS participants who were 65 years or older in 2016. From June 2016 to October 2017, 3,496 of these individuals underwent comprehensive neuropsychological test battery and informant interview, with dementia and MCI classified based on standard diagnostic criteria.

In total, 393 people were classified with dementia (10%), while 804 had MCI (22%), both of which approximate estimates reported by previous studies, according to the investigators. In further alignment with past research, age was a clear risk factor; each 5-year increment added 17% and 95% increased risk of MCI and dementia, respectively.

Compared with college-educated participants, individuals who did not graduate from high school had a 60% increased risk for both dementia (odds ratio, 1.6; 95% confidence interval, 1.1-2.3) and MCI (OR, 1.6; 95% CI, 1.2-2.2). Other educational strata were not associated with significant differences in risk.

Compared with White participants, Black individuals had an 80% increased risk of dementia (OR, 1.8; 95% CI, 1.2-2.7), but no increased risk of MCI. Conversely, non-White Hispanic individuals had a 40% increased risk of MCI (OR, 1.4; 95% CI, 1.0-2.0), but no increased risk of dementia, compared with White participants.

“Older adults racialized as Black and Hispanic are more likely to develop cognitive impairment and dementia because of historical and current structural racism and income inequality that restrict access to brain-health benefits and increase exposure to harm,” Dr. Manly said in a written comment.

VIENNA – The production of estrogen in the thalamus appears to be curtailed by just one dose of nicotine, equivalent to that in a cigarette, reveals a whole brain analysis of healthy women in the first study of its kind.

The findings were presented at the 35th European College of Neuropsychopharmacology (ECNP) Congress.

The researchers performed both MRI and positron emission tomography (PET) scans in 10 healthy women using a tracer that binds to aromatase, also known as estrogen synthase.

They found that, following an intranasal spray delivering 1 mg of nicotine, there was a significant reduction in estrogen synthase in both the right and left thalamus.

“For the first time, we can see that nicotine works to shut down the estrogen production mechanism in the brains of women,” said lead researcher Erika Comasco, PhD, department of neuroscience, Uppsala University, Sweden, in a release.

“We were surprised to see that this effect could be seen even with a single dose of nicotine, equivalent to just one cigarette, showing how powerful the effects of smoking are on a woman’s brain.”

Emphasizing the preliminary nature of the study and the need for a larger sample, she added: “We’re still not sure what the behavioral or cognitive outcomes are, only that nicotine acts on this area of the brain.

“However, we note that the affected brain system is a target for addictive drugs, such as nicotine.”

Previous research has revealed that women are less successful at quitting smoking than men, and appear to be more resistant to nicotine replacement therapy, and experience more relapses.

There is evidence to suggest that there is a complex interaction between sex and steroid hormones and the reward effect of nicotine, modulated by the dopaminergic system.

Moreover, women who smoke enter menopause earlier than nonsmokers, and have lower plasma estrogen levels, Dr. Camasco told this news organization.

Dr. Comasco explained that “besides its role in reproductive function and sexual behavior, estrogen has an impact on the brain wherever there are receptors, which is basically regions that are related to emotional regulation, cognitive function, and so on.”

Estrogen, she continued, has two main mechanisms of action, via dopaminergic and serotonergic signaling. However, levels of the hormone cannot be measured directly in the brain.

The researchers therefore turned to estrogen synthase, which regulates the synthesis of estrogen, and is highly expressed in the limbic system, a brain region associated with addiction.

Moreover, estrogen synthase levels can be measured in vivo, and previous animal studies have indicated that nicotine inhibits estrogen synthase.

To investigate its impact in humans, the researchers performed structural MRI and two ¹¹C-cetrozole PET scans in 10 healthy women.

The assessments were performed before and after the nasal administration of 1 mg of nicotine, the dose contained in one cigarette, via two sprays of a nasal spray each containing 0.5 mg of nicotine.

A whole brain analysis was then used to determine changes in nondisplaceable binding potential of ¹¹C-cetrozole to estrogen synthase between the two scans to indicate the availability of the enzyme at the two time points.

The results showed that, at baseline, high availability of estrogen synthase was observed in the thalamus, hypothalamus, and amygdala, with the highest levels in the right and left thalamus.

However, nicotine exposure was associated with a significant reduction in estrogen binding bilaterally in the thalamus when averaged across the participants (P < .01).

Region-of-interest analysis using within-individual voxel-wise comparison confirmed reduced estrogen synthase levels in both the right and left thalamus (P < .05), as well as in the subthalamic area.

Next, Dr. Comasco would like to test the impact of nicotine on estrogen synthase in men.

While men have lower levels of estrogen then women, “the reaction will take place anyway,” she said, although the “impact would be different.”

She would also like to look at the behavioral effects of reductions in estrogen synthase, and look at the effect of nicotine from a functional point of view.

Wim van den Brink, MD, PhD, professor of psychiatry and addiction at the Academic Medical Center, University of Amsterdam, commented that this is an “important first finding.”

“Smoking has many adverse effects in men and in women, but this particular effect of nicotine on the reduction of estrogen production in women was not known before,” he added in the release.

However, he underlined that tobacco addition is a “complex disorder” and it is “unlikely that this specific effect of nicotine on the thalamus explains all the observed differences in the development, treatment, and outcomes between male and female smokers.”

“It is still a long way from a nicotine-induced reduction in estrogen production to a reduced risk of nicotine addiction and negative effects of treatment and relapse in female cigarette smokers, but this work merits further investigation,” Dr. van den Brink said.

The study was funded by the Science for Life Laboratory/Uppsala University.

No relevant financial relationships were declared.

Dupilumab appears to improve clinical, symptomatic, histologic, and endoscopic aspects of eosinophilic esophagitis (EoE) up to 24 weeks, according to findings presented at the annual meeting of the American College of Gastroenterology.

The drug was also well tolerated, demonstrating consistency with the known dupilumab safety profile, said Evan S. Dellon, MD, a gastroenterologist at the University of North Carolina at Chapel Hill.

In May, the Food and Drug Administration approved dupilumab (Dupixent) for the treatment of EoE in adults and adolescents who are 12 years and older and weigh at least 40 kg (about 88 pounds), based on safety and efficacy data previously presented by Dr. Dellon and colleagues as part of the phase 3 LIBERTY-EoE-TREET study (NCT03633617).

“Dupilumab is now the only medication FDA approved to treat EoE in the U.S.,” Dr. Dellon said. “The findings here are that the pooled efficacy and safety data for parts A and B of the phase 3 trial are consistent with the results of the individual parts of the study that were previously reported, and which led to the drug being approved for EoE.”

EoE is a chronic, progressive, type 2 inflammatory disease of the esophagus, which can lead to symptoms of esophageal dysfunction that affect quality of life. Current treatment options often lack specificity, present adherence challenges, and provide suboptimal long-term disease control, Dr. Dellon said.

Dupilumab, a fully human monoclonal antibody manufactured by Regeneron Pharmaceuticals, blocks the shared receptor component for interleukin-4 and IL-13, which are central drivers of type 2 inflammation in EoE.
 

Study population difficult to treat

In the three-part, double-blind, placebo-controlled, phase 3 study, dupilumab was administered to 122 patients as 300-mg weekly doses through subcutaneous injection. In parts A and B, dupilumab demonstrated statistically significant and clinically meaningful improvement in adults and adolescents up to 24 weeks. In patients from part A who continued to an extended active treatment period called part C, efficacy was sustained to week 52.

Participants were included if they had EoE that hadn’t responded to high-dose proton pump inhibitors, had baseline esophageal biopsies with a peak intraepithelial eosinophilic count of 15 eosinophils per high-power field (eos/HPF) or higher in two or more esophageal regions, had a history of an average of two or more episodes of dysphagia per week in the 4 weeks prior to screening, had four or more episodes of dysphagia in the 2 weeks prior to randomization with two or more episodes that required liquids or medical attention, and had a baseline Dysphagia Symptom Questionnaire (DSQ) score of 10 or higher.

On the other hand, participants were excluded if they initiated or changed a food-elimination diet regimen or reintroduced a previously eliminated food group in the 6 weeks before screening, had other causes of esophageal eosinophilia, had a history of other inflammatory diseases such as Crohn’s disease or ulcerative colitis, or were treated with swallowed topical corticosteroids within 8 weeks prior to baseline.

Dr. Dellon and colleagues focused on co–primary endpoints: The proportion of patients who achieved peak esophageal intraepithelial eosinophil count of 6 eos/HPF or less, and the absolute change in DSQ score from baseline to week 24.

Key secondary endpoints included percentage change in eos/HPF, absolute change in EoE-Endoscopic Reference Score (EREFS), absolute change in EoE-Histologic Scoring System (EoE-HSS) grade score, and EoE-HSS stage score. Other secondary endpoints included percentage change in DSQ score and proportion of patients achieving less than 15 eos/HPF.

The baseline demographics and clinical characteristics were similar between the treatment and placebo groups. Importantly, about 70% had been treated with topical corticosteroids, and about 40% had a history of esophageal dilation, Dr. Dellon said. The DSQ scores, peak eosinophil counts, and EREFS scores were high, indicating an inflamed, symptomatic, and difficult-to-treat population.
 

Pooled parts A and B findings

Overall, dupilumab reduced peak esophageal intraepithelial eosinophil counts at week 24. In the dupilumab group, 59% of patients were down to 6 eos/HPF or less, compared with 5.9% in the placebo group. In a secondary endpoint, 77% of dupilumab patients were down to 15 eos/HPF, compared with 7.6% in the placebo group. The dupilumab group saw an 80% drop in baseline change, compared with 1.5% in the placebo group.

Dupilumab also reduced dysphagia symptoms and improved endoscopic features of EoE at week 24. The absolute change in DSQ score was –23.21 in the dupilumab group, compared with –12.69 in the placebo group. The percent change in DSQ score was –65.5% in the dupilumab group, compared with –38.2% in the placebo group. The absolute change in EREFS score was –3.95 in the dupilumab group, compared with –0.41 in the placebo group.

In addition, dupilumab reduced histologic scores at week 24. The absolute change in EoE-HSS grade score was –0.82 in the dupilumab group, compared with –0.1 in the placebo group. The absolute change in EoE-HSS stage score was –0.79 in the dupilumab group, compared with –0.09 in the placebo group.

Dupilumab demonstrated an acceptable safety profile, and no new safety signals were noted, Dr. Dellon said. The most common adverse events was injection-site reaction at 37.5% in the dupilumab group and 33.3% in the placebo group. The severe adverse events were not related to the medication.

“If patients have EoE, dupilumab might be an option for treatment. However, it’s important to realize that, in the phase 3 study, all patients were PPI nonresponders, most had been treated with topical steroids [and many were not responsive], and many had prior esophageal dilation,” Dr. Dellon said. “We don’t have a lot of data in more mild EoE patients, and insurances are currently requiring a series of authorization before patients might be able to get this medication. It’s best to talk to their doctor about whether the medication is a good fit for not.”

The study was sponsored by Sanofi and Regeneron Pharmaceuticals. Three of the authors are employees for and have stock options with Regeneron or Sanofi. The other authors reported consultant roles, advisory roles, and research support from numerous pharmaceutical companies, including Regeneron and Sanofi.

However, it’s important to realize that, in the phase 3 study, all patients were PPI nonresponders, most had been treated with topical steroids [and many were not responsive], and many had prior esophageal dilation,” Dr. Dellon said. “We don’t have a lot of data in more mild EoE patients, and insurances are currently requiring a series of authorization before patients might be able to get this medication. It’s best to talk to their doctor about whether the medication is a good fit for not.”

The study was sponsored by Sanofi and Regeneron Pharmaceuticals. Three of the authors are employees for and have stock options with Regeneron or Sanofi. The other authors reported consultant roles, advisory roles, and research support from numerous pharmaceutical companies, including Regeneron and Sanofi.

Dupilumab appears to improve clinical, symptomatic, histologic, and endoscopic aspects of eosinophilic esophagitis (EoE) up to 24 weeks, according to findings presented at the annual meeting of the American College of Gastroenterology.

The drug was also well tolerated, demonstrating consistency with the known dupilumab safety profile, said Evan S. Dellon, MD, a gastroenterologist at the University of North Carolina at Chapel Hill.

In May, the Food and Drug Administration approved dupilumab (Dupixent) for the treatment of EoE in adults and adolescents who are 12 years and older and weigh at least 40 kg (about 88 pounds), based on safety and efficacy data previously presented by Dr. Dellon and colleagues as part of the phase 3 LIBERTY-EoE-TREET study (NCT03633617).

“Dupilumab is now the only medication FDA approved to treat EoE in the U.S.,” Dr. Dellon said. “The findings here are that the pooled efficacy and safety data for parts A and B of the phase 3 trial are consistent with the results of the individual parts of the study that were previously reported, and which led to the drug being approved for EoE.”

EoE is a chronic, progressive, type 2 inflammatory disease of the esophagus, which can lead to symptoms of esophageal dysfunction that affect quality of life. Current treatment options often lack specificity, present adherence challenges, and provide suboptimal long-term disease control, Dr. Dellon said.

Dupilumab, a fully human monoclonal antibody manufactured by Regeneron Pharmaceuticals, blocks the shared receptor component for interleukin-4 and IL-13, which are central drivers of type 2 inflammation in EoE.
 

Study population difficult to treat

In the three-part, double-blind, placebo-controlled, phase 3 study, dupilumab was administered to 122 patients as 300-mg weekly doses through subcutaneous injection. In parts A and B, dupilumab demonstrated statistically significant and clinically meaningful improvement in adults and adolescents up to 24 weeks. In patients from part A who continued to an extended active treatment period called part C, efficacy was sustained to week 52.

Participants were included if they had EoE that hadn’t responded to high-dose proton pump inhibitors, had baseline esophageal biopsies with a peak intraepithelial eosinophilic count of 15 eosinophils per high-power field (eos/HPF) or higher in two or more esophageal regions, had a history of an average of two or more episodes of dysphagia per week in the 4 weeks prior to screening, had four or more episodes of dysphagia in the 2 weeks prior to randomization with two or more episodes that required liquids or medical attention, and had a baseline Dysphagia Symptom Questionnaire (DSQ) score of 10 or higher.

On the other hand, participants were excluded if they initiated or changed a food-elimination diet regimen or reintroduced a previously eliminated food group in the 6 weeks before screening, had other causes of esophageal eosinophilia, had a history of other inflammatory diseases such as Crohn’s disease or ulcerative colitis, or were treated with swallowed topical corticosteroids within 8 weeks prior to baseline.

Dr. Dellon and colleagues focused on co–primary endpoints: The proportion of patients who achieved peak esophageal intraepithelial eosinophil count of 6 eos/HPF or less, and the absolute change in DSQ score from baseline to week 24.

Key secondary endpoints included percentage change in eos/HPF, absolute change in EoE-Endoscopic Reference Score (EREFS), absolute change in EoE-Histologic Scoring System (EoE-HSS) grade score, and EoE-HSS stage score. Other secondary endpoints included percentage change in DSQ score and proportion of patients achieving less than 15 eos/HPF.

The baseline demographics and clinical characteristics were similar between the treatment and placebo groups. Importantly, about 70% had been treated with topical corticosteroids, and about 40% had a history of esophageal dilation, Dr. Dellon said. The DSQ scores, peak eosinophil counts, and EREFS scores were high, indicating an inflamed, symptomatic, and difficult-to-treat population.
 

Pooled parts A and B findings

Overall, dupilumab reduced peak esophageal intraepithelial eosinophil counts at week 24. In the dupilumab group, 59% of patients were down to 6 eos/HPF or less, compared with 5.9% in the placebo group. In a secondary endpoint, 77% of dupilumab patients were down to 15 eos/HPF, compared with 7.6% in the placebo group. The dupilumab group saw an 80% drop in baseline change, compared with 1.5% in the placebo group.

Dupilumab also reduced dysphagia symptoms and improved endoscopic features of EoE at week 24. The absolute change in DSQ score was –23.21 in the dupilumab group, compared with –12.69 in the placebo group. The percent change in DSQ score was –65.5% in the dupilumab group, compared with –38.2% in the placebo group. The absolute change in EREFS score was –3.95 in the dupilumab group, compared with –0.41 in the placebo group.

In addition, dupilumab reduced histologic scores at week 24. The absolute change in EoE-HSS grade score was –0.82 in the dupilumab group, compared with –0.1 in the placebo group. The absolute change in EoE-HSS stage score was –0.79 in the dupilumab group, compared with –0.09 in the placebo group.

Dupilumab demonstrated an acceptable safety profile, and no new safety signals were noted, Dr. Dellon said. The most common adverse events was injection-site reaction at 37.5% in the dupilumab group and 33.3% in the placebo group. The severe adverse events were not related to the medication.

Orimo and colleagues addressed the use of liver resection in patients with more than one HCC in the liver. Patients with no or Child-Pugh A/B cirrhosis were included in this single-center retrospective study of 1088 patients who underwent hepatectomy for Barcelona Clinic Liver Cancer (BCLC) stage 0 (n = 88), A (n = 750), or B (n = 250) HCC, with stages A and B subcategorized into A1 (single nodule 2-5 cm or ≤ 3 nodules ≤ 3 cm), A2 (single nodule 5-10 cm), A3 (single nodule ≥ 10 cm), B1 (2-3 nodules > 3 cm), and B2 (≥ 4 nodules). The 5-year overall survival (OS) rates for stage 0, A1, A2, A3, B1, and B2 patients were 70.4%, 74.2%, 63.8%, 47.7%, 47.5%, and 31.9%, respectively (P < .0001). Significant differences in overall survival (OS) were found between stages A1 and A2 (P = .0118), A2 and A3 (P = .0013), and B1 and B2 (P = .0050), but not between stages A3 and B1 (P = .4742). In stage B1 patients, Child-Pugh B cirrhosis was the only independent prognostic factor for OS. The authors concluded that hepatectomy is beneficial in patients with three or fewer hepatocellular carcinomas and either no or Child-Pugh class A cirrhosis, with the long-term results being comparable to those in patients who underwent a resection of a single HCC. Therefore, resection of up to three HCC is safe and should be considered in clinically appropriate patients.

Many patients with multifocal HCC are not eligible for liver-directed therapies. The standard of care for first-line systemic therapy is the combination of atezolizumab and bevacizumab, as reported in the IMbrave150 clinical trial. Fulgenzi and colleagues published the results of a multicenter prospective observational study, AB-Real, that included 433 patients who received atezolizumab and bevacizumab in routine clinical practice. The investigators confirmed the efficacy of the combination and found that portal vein tumor thrombosis and worse albumin-bilirubin grade were independent prognostic factors for poor OS and were associated with an increased risk for hemorrhagic events. In addition, the authors reported that the overall response rate (ORR) predicted better outcomes, including longer OS. Therefore, atezolizumab and bevacizumab remains a safe and effective first-line treatment for many patients with unresectable HCC.

Finally, Finn and colleagues reported the results of an open-label, noncomparative cohort of the REACH-2 study of ramucirumab in 47 patients with advanced HCC and an alpha-fetoprotein (AFP) level ≥ 400 ng/mL. These patients had previously received one to two lines of systemic therapy, excluding sorafenib or chemotherapy. Lenvatinib was the most common prior systemic therapy (n = 20; 43%). Others included immune checkpoint inhibitor (CPI) monotherapies (n = 11), CPI/antiangiogenic therapy (n = 14), or dual CPI therapy (n = 5). The ORR was 10.6% (95% CI 1.8-19.5) and disease control rate was 46.8% (95% CI 32.5-61.1), with a median duration of response of 8.3 months (95% CI 2.4 to not reached). The grade 3 or more adverse event rate was 57%, with hypertension (11%) being the most common, allowing the authors to conclude that ramucirumab offers clinically significant efficacy with no new safety signals in this setting. Therefore, ramucirumab remains as a safe and effective later-line treatment option for patients with unresectable HCC and an AFP ≥ 400 ng/mL.

Taking call is one of the more challenging - and annoying - aspects of the job for many physicians. Calls may wake them up in the middle of the night and can interfere with their at-home activities. In Medscape’s Employed Physicians Report, 37% of respondents said they have from 1 to 5 hours of call per month; 19% said they have 6 to 10 hours; and 12% have 11 hours or more.

“Even if you don’t have to come in to the ED, you can get calls in the middle of the night, and you may get paid very little, if anything,” said Robert Bitterman MD, JD, an emergency physician and attorney in Harbor Springs, Mich.

And responding to the calls is not optional. Dr. Bitterman said if on-call physicians don’t perform their duties, they could lose their hospital privileges, be fined by the federal government, or be sued for malpractice.

On-call activities are regulated by the federal Emergency Medical Treatment and Active Labor Act (EMTALA). Dr. Bitterman said it’s rare for the federal government to prosecute on-call physicians for violating EMTALA. Instead, it’s more likely that the hospital will be fined for EMTALA violations committed by on-call physicians.

However, the hospital passes the on-call obligation on to individual physicians through medical staff bylaws. Physicians who violate the bylaws may have their privileges restricted or removed, Dr. Bitterman said. Physicians could also be sued for malpractice, even if they never treated the patient, he added.
 

After-hours call duty in physicians’ practices

A very different type of call duty is having to respond to calls from one’s own patients after regular hours. Unlike doctors on ED call, who usually deal with patients they have never met, these physicians deal with their established patients or those of a colleague in their practice.

Courts have established that physicians have to provide an answering service or other means for their patients to contact them after hours, and the doctor must respond to these calls in a timely manner.

In a 2015 Louisiana ruling, a cardiologist was found liable for malpractice because he didn’t respond to an after-hours call from his patient. The patient tried several times to contact the cardiologist but got no reply.

Physicians may also be responsible if their answering service does not send critical messages to them immediately, if it fails to make appropriate documentation, or if it sends inaccurate data to the doctor.
 

Cases when on-call doctors didn’t respond

The Office of the Inspector General (OIG) of the U.S. Health and Human Services Administration oversees federal EMTALA violations and regularly reports them.

In 2018, the OIG fined a hospital in Waterloo, Iowa, $90,000 when an on-call cardiologist failed to implant a pacemaker for an ED patient. According to the OIG’s report, the patient arrived at the hospital with heart problems. Reached by phone, the cardiologist directed the ED physician to begin transcutaneous pacing but asked that the patient be transferred to another hospital for placement of the pacemaker. The patient died after transfer.

The OIG found that the original cardiologist could have placed the pacemaker, but, as often happens, it only fined the hospital, not the on-call physician for the EMTALA violation.

EMTALA requires that hospitals provide on-call specialists to assist emergency physicians with care of patients who arrive in the ED. In specialties for which there are few doctors to choose from, the on-call specialist may be on duty every third night and every third weekend. This can be daunting, especially for specialists who’ve had a grueling day of work.

Occasionally, on-call physicians, fearful they could make a medical error, request that the patient be transferred to another hospital for treatment. This is what a neurosurgeon who was on call at a Topeka, Kan., hospital did in 2001. Transferred to another hospital, the patient underwent an operation but lost sensation in his lower extremities. The patient sued the on-call neurosurgeon for negligence.

During the trial, the on-call neurosurgeon testified that he was “feeling run-down because he had been an on-call physician every third night for more than 10 years.” He also said this was the first time he had refused to see a patient because of fatigue, and he had decided that the patient “would be better off at a trauma center that had a trauma team and a fresher surgeon.”

The neurosurgeon successfully defended the malpractice suit, but Dr. Bitterman said he might have lost had there not been some unusual circumstances in the case. The court ruled that the hospital had not clearly defined the duties of on-call physicians, and the lawsuit didn’t cite the neurosurgeon’s EMTALA duty.
 

On-call duties defined by EMTALA

EMTALA sets the overall rules for on-call duties, which each hospital is expected to fine-tune on the basis of its own particular circumstances. Here are some of those rules, issued by the Centers for Medicare & Medicaid Services and the OIG.

Only an individual physician can be on call. The hospital’s on-call schedule cannot name a physician practice.

Call applies to all ED patients. Physicians cannot limit their on-call responsibilities to their own patients, to patients in their insurance network, or to paying patients.

There may be some gaps in the call schedule. The OIG is not specific as to how many gaps are allowed, said Nick Healey, an attorney in Cheyenne, Wyo., who has written about on-call duties. Among other things, adequate coverage depends on the number of available physicians and the demand for their services. Mr. Healey added that states may require more extensive availability of on-call physicians at high-level trauma centers.

Hospitals must have made arrangements for transfer. Whenever there is a gap in the schedule, hospitals need to have a designated hospital to send the patient to. Hospitals that unnecessarily transfer patients will be penalized.

The ED physician calls the shots. The emergency physician handling the case decides if the on-call doctor has to come in and treat the patient firsthand.

The on-call physician may delegate the work to others. On-call physicians may designate a nurse practitioner or physician assistant, but the on-call physician is ultimately responsible. The ED doctor may require the physician to come in anyway, according to Todd B. Taylor, MD, an emergency physician in Phoenix, who has written about on-call duties. Dr. Bitterman noted that the physician may designate a colleague to take their call, but the substitute has to have privileges at the hospital.

Physicians may do their own work while on call. Physicians can perform elective surgery while on call, provided they have made arrangements if they then become unavailable for duty, Dr. Taylor said. He added that physicians can also have simultaneous call at other hospitals, provided they make arrangements.
 

The hospital fine-tunes call obligations

The hospital is expected to further define the federal rules. For instance, the CMS says physicians should respond to calls within a “reasonable period of time” and requires hospitals to specify response times, which may be 15-30 minutes for responding to phone calls and traveling to the ED, Dr. Bitterman said.

The CMS says older physicians can be exempted from call. The hospital determines the age at which physicians can be exempted. “Hospitals typically exempt physicians over age 65 or 70, or when they have certain medical conditions,” said Lowell Brown, a Los Angeles attorney who deals with on-call duties.

The hospital also sets the call schedule, which may result in uncovered periods in specialties in which there are few physicians to draw from, according to Mr. Healey. He said many hospitals still use a simple rule of thumb, even though it has been dismissed by the CMS. Under this so-called “rule of three,” hospitals that have three doctors or fewer in a specialty do not have to provide constant call coverage.

On-call rules are part of the medical staff bylaws, and they have to be approved by the medical staff. This may require delicate negotiations between the staff’s leadership and administrators, Dr. Bitterman said.

It is often up to the emergency physician on duty to enforce the hospital’s on-call rules, Dr. Taylor said. “If the ED physician is having trouble, he or she may contact the on-call physician’s department chairman or, if necessary, the chief of the medical staff and ask that person to deal with the physician,” Dr. Taylor said.

The ED physician has to determine whether the patient needs to be transferred to another hospital. Dr. Taylor said the ED physician must fill out a transfer form and obtain consent from the receiving hospital.

If a patient has to be transferred because an on-call physician failed to appear, the originating hospital has to report this to the CMS, and the physician and the hospital can be cited for an inappropriate transfer and fined, Mr. Brown said. “The possibility of being identified in this way should be a powerful incentive to accept call duty,” he added.
 

Malpractice exposure of on-call physicians

When on-call doctors provide medical advice regarding an ED patient, that advice may be subject to malpractice litigation, Dr. Taylor said. “Even if you only give the ED doctor advice over the phone, that may establish a patient-physician relationship and a duty that patient can cite in a malpractice case,” he noted.

Refusing to take call may also be grounds for a malpractice lawsuit, Dr. Bitterman said. Refusing to see a patient would not be considered medical negligence, he continued, because no medical decision is made. Rather, it involves general negligence, which occurs when physicians fail to carry out duties expected of them.

Dr. Bitterman cited a 2006 malpractice judgment in which an on-call neurosurgeon in Missouri was found to be generally negligent. The neurosurgeon had arranged for a colleague in his practice to take his call, but the colleague did not have privileges at the hospital.

A patient with a brain bleed came in and the substitute was on duty. The patient had to be transferred to another hospital, where the patient died. The court ordered that the on-call doctor and the originating hospital had to split a fine of $400,800.
 

On-call physicians can be charged with abandonment

Dr. Bitterman said that if on-call physicians do not provide expected follow-up treatment for an ED patient, they could be charged with abandonment, which is a matter of state law and involves filing a malpractice lawsuit.

Abandonment involves unilaterally terminating the patient relationship without providing notice. There must be an established relationship, which, in the case of call, is formed when the doctor comes to the ED to examine or admit the patient, Dr. Bitterman said. He added that the on-call doctor’s obligation applies only to the medical condition the patient came in for.

Even when an on-call doctor does not see a patient, a relationship can be established if the hospital requires its on-call doctors to make follow-up visits for ED patients, Dr. Taylor said. At some hospitals, he said, on-call doctors have blanket agreements to provide follow-up care in return for not having to arrive in the middle of the night during the ED visit.

Dr. Taylor gave an example of the on-call doctor’s obligation: “The ED doctor puts a splint on the patient’s ankle fracture, and the orthopedic surgeon on call agrees to follow up with the patient within the next few days. If the orthopedic surgeon refuses to follow up without making a reasonable accommodation, it may become an issue of patient abandonment.”
 

Now everyone has a good grasp of the rules

Fifteen years ago, many doctors were in open revolt against on-call duties, but they are more accepting now and understand the rules better, Mr. Healey said.

“Many hospitals have begun paying some specialists for call and designating hospitalists and surgicalists to do at least some of the work that used to be expected of on-call doctors,” he said.

According to Dr. Taylor, today’s on-call doctors often have less to do than in the past. “For example,” he said, “the hospitalist may admit an orthopedic patient at night, and then the orthopedic surgeon does the operation the next day. We’ve had EMTALA for 36 years now, and hospitals and doctors know how call works.”
