Surgical site infections are one of the top causes of postoperative morbidity and death worldwide, but there is little agreement and much debate over the most effective wound dressing to improve outcomes and reduce the health care burden.

Recent clinical trials have indicated that transparent, semiocclusive films have advantages over gauze held by adhesive tape.

But current transparent film bandages may become dislodged during activities such as showering, say authors of a pilot study published in the Journal of Wound Care. Patients may not realize the bandage has been disrupted, which can lead to infection.

The paper describes a novel product called DrySee dressing (DSD), which features a liquid indicator that turns blue around the edges if moisture is present.

“Clinicians, patients, and caregivers are alerted to the loss of dressing integrity and can replace the dressing when any portion of the perimeter changes to a blue [color],” the authors explain. “In addition, the dressing turns blue when the central pad is saturated with fluid, allowing the patient or provider to change the dressing.”

DSD is indicated for wounds that have low levels of exudate.
 

Two transparent film dressings compared

Researchers recruited 20 patients from the general population in Pittsburgh, for a small pilot study to test DSD against a comparator film dressing (3M Tegaderm + Pad). The volunteers received “a small stipend,” according to the paper.

A 1.5-centimeter incision was made in both forearms of each volunteer. The forearms were randomized regarding which got which bandage. Both bandages have been cleared by the U.S. Food and Drug Administration as nonsignificant-risk devices.

Volunteers were instructed to wear the dressing and continue their typical activities of daily living.

The average age of the volunteers was 52 years (range, 20-80 years). Among the 20 volunteers, 11 reported no comorbidities, and 45% reported at least one comorbidity.

Most of the volunteers favored DSD over the comparator in a postoperative survey – 75% to 25%, according to the report.

The wear time between the two transparent dressings across all subjects was 1.4 days. There was no difference in wear time, logged by the volunteers, between the two groups.   

There were no infectious complications, the paper states.

The maker, DrySee (Houston), which holds three patents on the product, supported the research with an unrestricted grant.

DrySee CEO Brad Greer told this news organization, “With DrySee, you know when to change your dressing. All other dressings look the same wet, saturated, or dry.”

He said the study confirms what they have seen in practice, adding that the product is unique.

“No one else in the world has this technology,” Mr. Greer said.
 

Surgeons want to see more data

Heather Evans, MD, a general surgeon with the Medical University of South Carolina, MUSC Health, Charleston, who was not involved with the study, praised the color-indicator design and said she liked the bandage’s narrow indication for low-exudate wounds.

She said in an interview, “It’s a lot to put on a layperson to suddenly know how to take care of wounds when you leave the hospital.”

Giving them the confidence that their wound is safe if the blue doesn’t appear “is a really cool concept,” she said.

She said that, although the volunteers included some elderly people and people with conditions such as diabetes that could affect wound healing, the bandage needs to be tested with a bigger trial to see if it is effective outside controlled conditions.

She also said that some occlusive dressings will be more durable and stay on days longer than DSD or the comparator, which may affect the choice for some.

“The average length of dressing time in this study was less than 2 days,” she pointed out.

Jim Rickert, MD, an orthopedic surgeon with Indiana University Health Bedford, who was not involved with the study, agreed that any surgical or wound dressing, including transparent films, can become dislodged, and said, “This type of product has promise but this is a small pilot study. I would want to see results from a trial of actual surgical patients to see if this type of dressing did indeed decrease post-op infections compared to standard dressing materials.”

Not all are convinced either that there is a need to be filled or that DSD will be the right solution.

Therese Duane, MD, a general surgeon with Texas Health Harris Methodist Fort Worth, who was not part of the study, said in an interview that she “has no issues with the current products.”

She added that more information is needed before considering DSD a better solution, including animal studies and use “on very sick patients.”

“Twenty volunteers with cuts on their arm is barely a start for comparison,” she said.

The authors, led by Kristy Breisinger, a research analyst with the SerenaGroup Research Foundation in Cambridge, Mass., acknowledged the limitations, including the small sample size and that the trial was conducted at only one institution. Additionally, the analysis is based on descriptive statistics.

They write that the trial design was chosen “to simulate a real-world setting that is not always achievable in animal studies.”

The research was sponsored by an unrestricted grant from the maker of DSD, DrySee Inc., in Houston.

Mr. Greer is DrySee’s CEO. The authors and Dr. Duane, Dr. Rickert, and Dr. Evans declared no relevant financial relationships.

Response-adapted de-escalation of immunotherapy in patients with advanced melanoma may lead to considerable savings for payers – close to $20,000 per patient – compared with standard immunotherapy, an economic analysis found.

“The rising costs of cancer therapies are becoming untenable for both patients and payers, and there is both clinical and economic benefit to finding less expensive treatment alternatives,” Wolfgang Kunz, MD, University Hospital, Ludwig Maximilian University of Munich, told this news organization.

This economic analysis “highlights that leveraging modern diagnostic capabilities can do just that: Pairing drug regimens with CT-image analysis to optimize dosages can reduce health care costs and improve clinical outcomes,” Dr. Kunz said.

The study was published online in JAMA Dermatology.

While the use of immunotherapies over the past decade has improved the prognosis for patients with advanced melanoma, these drugs come with a hefty price tag.

One potential way to help reduce costs: de-escalate therapy. The ADAPT-IT trial demonstrated similar progression-free and overall survival among patients who received response-adapted ipilimumab discontinuation and those who received standard of care.

In the current analysis, Dr. Kunz and colleagues wanted to understand whether this response-adapted approach was also cost effective.

The team applied economic modeling to data from the ADAPT-IT trial as well as CheckMate 067, in which patients received standard of care four doses of combination ipilimumab-nivolumab followed by nivolumab monotherapy. In the ADAPT-IT trial, patients also initially received the immunotherapy combination but had CT scans to determine their response after two doses; if they responded, patients discontinued ipilimumab and continued with nivolumab monotherapy.

Overall, ADAPT-IT showed that responders could forgo the additional two doses of ipilimumab plus nivolumab while maintaining similar progression-free survival and overall survival seen at 18 months in the CheckMate 067 trial.

The current economic analysis, based on 41 patients from ADAPT-IT and 314 from CheckMate 067, showed a potential reduction in health care costs of $19,891 per patient with the response-adapted approach.

Response-adapted treatment was the cost-effective option in 94% of simulated scenarios.

When extrapolated to 2019 incidence rates of distant melanoma cases, yearly national savings could reach about $58 million.

“In the relatively small space of immunotherapies in advanced melanoma, we hope this analysis motivates clinicians to consider response-adapted treatment,” Dr. Kunz told this news organization.

“On the larger scale, this analysis serves as a stepping stone to more response-guided treatment protocols,” Dr. Kunz added. “With drug costs rising and imaging capabilities growing, more frequent image-guided adjustments are a perfect fit into the personalized care model.”

When applying the cost savings noted in this analysis across all treated patients, “the economic impact may be profound,” said Joseph Skitzki, MD, surgical oncologist, Roswell Park Comprehensive Cancer Center, Buffalo, N.Y., who wasn’t involved in the study. The “financial toxicity of cancer care is increasingly recognized as a potential barrier to optimal outcomes and any measures to mitigate cost may be impactful.”

However, Dr. Skitzki said several caveats need to be considered.

One is that the data included from ADAPT-IT only included 41 patients, compared with 314 patients from CheckMate 067.

“It is possible that a larger real-world study utilizing the ADAPT-IT protocol may not be as favorable in terms of outcomes and could lessen the economic impact of de-escalation, although any form of de-escalation is likely to have a cost benefit,” Dr. Skitzki said in an interview.

A real-world response–adapted de-escalation clinical trial, with an emphasis on costs and a benchmark of similar progression-free and overall survival, should be conducted before the de-escalated option becomes “practice changing,” Dr. Skitzki said.

Jeffrey Weber, MD, PhD, deputy director, Perlmutter Cancer Center, NYU Langone Health, New York, also urged caution in interpreting the results.

“I would not base treatment decisions on a small sampling of 41 patients in the absence of a randomized comparison,” Dr. Weber told this news organization. “Without a proper comparison, I would not advocate using only two doses of ipilimumab-nivolumab to make decisions on treatment.”

Dr. Skitzki added that, while “studies like this one are desperately needed to lessen the economic impact of new and emerging combination immunotherapies,” there is likely also a “disincentive for pharmaceutical companies to conduct this type of research.”

This research had no specific funding. Dr. Kunz and Dr. Skitzki reported no relevant conflicts of interest. Dr. Weber disclosed relationships with Merck, Genentech, AstraZeneca, Pfizer, Regeneron, and GSK, among others, and holds equity in Cytomx, Biond, NexImmune, and Immunomax.

Medicare’s recently announced 2023 physician payment rule likely trims doctors’ pay even as it aims to expand patients’ access to behavioral health services, chronic pain management, and hearing screening. The rule also seeks to ease financial and administrative burdens on accountable care organizations (ACOs).

But physician groups’ initial reactions centered on what the American Medical Association describes as a “damaging across-the-board reduction” of 4.4% in a base calculation, known as a conversion factor.

The reduction is only one of the current threats to physician’s finances, Jack Resneck Jr, MD, AMA’s president, said in a statement. Medicare payment rates also fail to account for inflation in practice costs and COVID-related challenges. Physician’s Medicare payments could be cut by nearly 8.5% in 2023, factoring in other budget cuts, Dr. Resneck said in the statement.

That “would severely impede patient access to care due to the forced closure of physician practices and put further strain on those that remained open during the pandemic,” he said.

A key driver of these cuts is a law that was intended to resolve budget battles between Congress and physicians, while also transitioning Medicare away from fee-for-service payments and pegging reimbursement to judgments about value of care provided. The Centers for Medicare & Medicaid Services thus had little choice about cuts mandated by the Medicare Access and CHIP Reauthorization Act (MACRA) of 2015.

For AMA and other physician groups, the finalization of the Medicare rule served as a rallying point to build support for pending legislation intended to stave off at least some payment cuts.

Federal officials should act soon to block the expected cuts before this season of Congress ends in January, said Anders Gilberg, senior vice president for government affairs at the Medical Group Management Association, in a statement.

“This cannot wait until next Congress – there are claims-processing implications for retroactively applying these policies,” Mr. Gilberg said.

He said MGMA would work with Congress and CMS “to mitigate these cuts and develop sustainable payment policies to allow physician practices to focus on treating patients instead of scrambling to keep their doors open.”
 

Chronic budget battles

Once seen as a promising resolution to chronic annual budget battles between physicians and Medicare, MACRA has proven a near-universal disappointment. A federal advisory commission in 2018 recommended that Congress scrap MACRA’s  Merit-based Incentive Payment System (MIPS) and replace it with a new approach for attempting to tie reimbursement to judgments about the quality of medical care.

MACRA replaced an earlier budgeting approach on Medicare physician pay, known as the sustainable growth rate (SGR). Physician groups successfully lobbied Congress for many years to block threatened Medicare payment cuts. Between 2003 and April 2014, Congress passed 17 laws overriding the cuts to physician pay that the lawmakers earlier mandated through the SGR.

A similar pattern has emerged as Congress now acts on short-term fixes to stave off MACRA-mandated cuts. A law passed last December postponed cuts in physician pay from MACRA and federal budget laws.

And more than 70 members of the House support a bill (HR 8800) intended to block a slated 4.4% MACRA-related cut in physician pay for 2023. Two physicians, Rep. Ami Bera, MD, (D-CA) and Rep. Larry Bucshon (R-IN) sponsored the bill.

Among the groups backing the bill are the AMA, American Academy of Family Physicians, and American College of Physicians. The lawmakers may try to attach this bill to a large spending measure, known as an omnibus, that Congress will try to clear in December to avoid a partial government shutdown.

In a statement, Tochi Iroku-Malize, MD, MPH, MBA, the president of AAFP, urged Congress to factor in inflation in setting physician reimbursement and to reconsider Medicare’s approach to paying physicians.

“It’s past time to end the untenable physician payment cuts – which have now become an annual threat to the stability of physician practices – caused by Medicare budget neutrality requirements and the ongoing freeze in annual payment updates,” Dr. Iroku-Malize said.

Congress also needs to retool its approach to alternative payment models (APMs) intended to improve the quality of patient care, Dr. Iroku-Malize said.

“Physicians in APMs are better equipped to address unmet social needs and provide other enhanced services that are not supported by fee-for-service payment rates,” Dr. Iroku-Malize said. “However, insufficient Medicare fee-for-service payment rates, inadequate support, and burdensome timelines are undermining the move to value-based care and exacerbating our nation’s underinvestment in primary care.”
 

Policy changes

But the new rule did have some good news for family physicians, Dr. Iroku-Malize told this news organization in an email.

CMS said it will pay psychologists and social workers to help manage behavioral health needs as part of the primary care team, in addition to their own services. This change will give primary care practices more flexibility to coordinate with behavioral health professionals, Dr. Iroku-Malize noted.

“We know that primary care physicians are the first point of contact for many patients, and behavioral health integration increases critical access to mental health care, decreases stigma for patients, and can prevent more severe medical and behavioral health events,” she wrote.

CMS also eased a supervision requirement for nonphysicians providing behavioral health services.

It intends to allow certain health professionals to provide this care without requiring that a supervising physician or nurse practitioner be physically on site. This shift from direct supervision to what’s called general supervision applies to marriage and family therapists, licensed professional counselors, addiction counselors, certified peer recovery specialists, and behavioral health specialists, CMS said.

Other major policy changes include:

Medicare will pay for telehealth opioid treatment programs allowing patients to initiate treatment with buprenorphine. CMS also clarified that certain programs can bill for opioid use disorder treatment services provided through mobile units, such as vans.

Medicare enrollees may see audiologists for nonacute hearing conditions without an order from a physician or nurse practitioner. The policy is meant to allow audiologists to examine patients to prescribe, fit, or change hearing aids, or to provide hearing tests unrelated to disequilibrium.

CMS created new reimbursement codes for chronic pain management and treatment services to encourage clinicians to see patients with this condition. The codes also are meant to encourage practitioners already treating Medicare patients with chronic pain to spend more time helping them manage their condition “within a trusting, supportive, and ongoing care partnership,” CMS said.

CMS also made changes to the Medicare Shared Savings Program (MSSP) intended to reduce administrative burdens and offer more financial support to practices involved in ACOs. These steps include expanding opportunities for certain low-revenue ACOs to share in savings even if they do not meet a target rate.

Medicare’s recently announced 2023 physician payment rule likely trims doctors’ pay even as it aims to expand patients’ access to behavioral health services, chronic pain management, and hearing screening. The rule also seeks to ease financial and administrative burdens on accountable care organizations (ACOs).

But physician groups’ initial reactions centered on what the American Medical Association describes as a “damaging across-the-board reduction” of 4.4% in a base calculation, known as a conversion factor.

The reduction is only one of the current threats to physician’s finances, Jack Resneck Jr, MD, AMA’s president, said in a statement. Medicare payment rates also fail to account for inflation in practice costs and COVID-related challenges. Physician’s Medicare payments could be cut by nearly 8.5% in 2023, factoring in other budget cuts, Dr. Resneck said in the statement.

That “would severely impede patient access to care due to the forced closure of physician practices and put further strain on those that remained open during the pandemic,” he said.

A key driver of these cuts is a law that was intended to resolve budget battles between Congress and physicians, while also transitioning Medicare away from fee-for-service payments and pegging reimbursement to judgments about value of care provided. The Centers for Medicare & Medicaid Services thus had little choice about cuts mandated by the Medicare Access and CHIP Reauthorization Act (MACRA) of 2015.

For AMA and other physician groups, the finalization of the Medicare rule served as a rallying point to build support for pending legislation intended to stave off at least some payment cuts.

Federal officials should act soon to block the expected cuts before this season of Congress ends in January, said Anders Gilberg, senior vice president for government affairs at the Medical Group Management Association, in a statement.

“This cannot wait until next Congress – there are claims-processing implications for retroactively applying these policies,” Mr. Gilberg said.

He said MGMA would work with Congress and CMS “to mitigate these cuts and develop sustainable payment policies to allow physician practices to focus on treating patients instead of scrambling to keep their doors open.”
 

Chronic budget battles

Once seen as a promising resolution to chronic annual budget battles between physicians and Medicare, MACRA has proven a near-universal disappointment. A federal advisory commission in 2018 recommended that Congress scrap MACRA’s  Merit-based Incentive Payment System (MIPS) and replace it with a new approach for attempting to tie reimbursement to judgments about the quality of medical care.

MACRA replaced an earlier budgeting approach on Medicare physician pay, known as the sustainable growth rate (SGR). Physician groups successfully lobbied Congress for many years to block threatened Medicare payment cuts. Between 2003 and April 2014, Congress passed 17 laws overriding the cuts to physician pay that the lawmakers earlier mandated through the SGR.

A similar pattern has emerged as Congress now acts on short-term fixes to stave off MACRA-mandated cuts. A law passed last December postponed cuts in physician pay from MACRA and federal budget laws.

And more than 70 members of the House support a bill (HR 8800) intended to block a slated 4.4% MACRA-related cut in physician pay for 2023. Two physicians, Rep. Ami Bera, MD, (D-CA) and Rep. Larry Bucshon (R-IN) sponsored the bill.

Among the groups backing the bill are the AMA, American Academy of Family Physicians, and American College of Physicians. The lawmakers may try to attach this bill to a large spending measure, known as an omnibus, that Congress will try to clear in December to avoid a partial government shutdown.

In a statement, Tochi Iroku-Malize, MD, MPH, MBA, the president of AAFP, urged Congress to factor in inflation in setting physician reimbursement and to reconsider Medicare’s approach to paying physicians.

“It’s past time to end the untenable physician payment cuts – which have now become an annual threat to the stability of physician practices – caused by Medicare budget neutrality requirements and the ongoing freeze in annual payment updates,” Dr. Iroku-Malize said.

Congress also needs to retool its approach to alternative payment models (APMs) intended to improve the quality of patient care, Dr. Iroku-Malize said.

“Physicians in APMs are better equipped to address unmet social needs and provide other enhanced services that are not supported by fee-for-service payment rates,” Dr. Iroku-Malize said. “However, insufficient Medicare fee-for-service payment rates, inadequate support, and burdensome timelines are undermining the move to value-based care and exacerbating our nation’s underinvestment in primary care.”
 

Policy changes

But the new rule did have some good news for family physicians, Dr. Iroku-Malize told this news organization in an email.

CMS said it will pay psychologists and social workers to help manage behavioral health needs as part of the primary care team, in addition to their own services. This change will give primary care practices more flexibility to coordinate with behavioral health professionals, Dr. Iroku-Malize noted.

“We know that primary care physicians are the first point of contact for many patients, and behavioral health integration increases critical access to mental health care, decreases stigma for patients, and can prevent more severe medical and behavioral health events,” she wrote.

CMS also eased a supervision requirement for nonphysicians providing behavioral health services.

It intends to allow certain health professionals to provide this care without requiring that a supervising physician or nurse practitioner be physically on site. This shift from direct supervision to what’s called general supervision applies to marriage and family therapists, licensed professional counselors, addiction counselors, certified peer recovery specialists, and behavioral health specialists, CMS said.

ORLANDO – Treatment with a renin-angiotensin system (RAS) inhibitor is widely accepted as standard practice for slowing progression of chronic kidney disease (CKD), but data have been inconsistent as to whether there is benefit to continuing RAS inhibition when patients develop advanced CKD, defined as an estimated glomerular filtration rate (eGFR) of less than 30 mL/min per 1.73 m².

Now, in STOP ACEi, a new multicenter, randomized trial of 411 patients, maintaining treatment with a RAS inhibitor in adults with advanced and progressive CKD did not cause a clinically relevant change in kidney function, or in the long-term rate of decline in kidney function, compared with stopping treatment, for 3 years.

People who continued RAS inhibitor treatment did not develop a significant or clinically relevant decrease in eGFR, the study’s primary outcome, both overall as well as in several prespecified subgroups compared with those who discontinued treatment, said Sunil Bhandari, MBChB, PhD, and associates, who presented the research in a poster at the annual meeting of the American Society of Nephrology.

“I hope these results will reassure clinicians to continue ACE inhibitors or ARBs” in patients with advanced CKD, “with their known beneficial cardiovascular effects,” Dr. Bhandari said in an interview.

The results were simultaneously published in the New England Journal of Medicine.
 

Similar eGFR levels after 3 years

While it’s clear that in patients with mild or moderate CKD, treatment with a RAS inhibitor, which includes angiotensin-converting enzyme (ACE) inhibitors and angiotensin-receptor blockers (ARBs), reduces blood pressure, slows decline in eGFR, reduces proteinuria, and delays progression to advanced CKD, there has been little evidence that the use of RAS inhibitors benefits patients with advanced CKD.

Data from previous trials have been inconsistent regarding whether the use of RAS inhibitors is nephroprotective in patients with advanced CKD, say Dr. Bhandari, a nephrologist and professor at Hull York Medical School, Hull, England, and colleagues.

“Current guidelines do not provide specific advice on whether to continue or stop ACE inhibitors or ARBs for advanced chronic kidney disease,” they also note.

And so they decided to assess whether discontinuation of ACE inhibitors/ARBs could slow progression of CKD in patients with advanced CKD.

Three years after 206 study participants stopped RAS inhibitor treatment, the least-squares mean eGFR was 12.6 mL/min per 1.73m² in the discontinuation group and 13.3 mL/min per 1.73 m² in the 205 patients in the continuation group, a difference that was not significant.

In addition to the primary outcome, 62% of patients who stopped RAS inhibitor treatment and 56% of those who continued developed end-stage kidney disease or required renal-replacement therapy, which translated into an adjusted hazard ratio of 1.28 for this outcome among those who discontinued compared with those who continued, which was just short of significance (95% CI, 0.99-1.65).

The two study groups also showed no significant differences in the 3-year incidence of hospitalization for any reason, cardiovascular events, or deaths. The two groups also showed no meaningful differences in various domains of quality of life and no differences in serious adverse effects.
 

Participants had an eGFR less than 30 mL/min per 1.73 m²

The study ran at 39 United Kingdom centers in 2014-2019. Investigators enrolled adults with an eGFR of less than 30 mL/min per 1.73 m² who were not on dialysis and had not received a kidney transplant. In addition, all enrolled patients had to have an annual drop in eGFR of more than 2 mL/min per 1.73 m² during the prior 2 years and had to have been on treatment with at least one RAS inhibitor for more than 6 months.

The randomization protocol insured balanced distribution of subjects between the two study arms by age, eGFR, presence of diabetes, and level of proteinuria, among other factors. The study design also mandated that participants maintain a blood pressure of no more than 140/85 mm Hg.

Those who discontinued RAS-inhibitor treatment could receive any guideline-recommended antihypertensive agent that was not a RAS inhibitor, although adding a RAS inhibitor was permitted as a last treatment resort.

People in the maintenance group could receive whichever additional antihypertensive agents their treating clinicians deemed necessary for maintaining the target blood pressure.

The enrolled population was a median age of 63 years old and 68% were men. Their average eGFR at baseline was 18 mL/min per 1.73 m², and 118 (29%) had an eGFR of less than 15 mL/min per 1.73 m². Their median level of proteinuria was 115 mg/mmol (about 1,018 mg/g). Diabetes was prevalent in 37%, and 58% of participants were taking at least three antihypertensive medications at entry.

Among the study’s limitations, the researchers cited the open-label design, which may have affected clinical care and the tally of subjective endpoints, including quality of life and exercise capacity. Also, because the study enrolled people who were on a RAS inhibitor at the time of randomization, it did not include anyone who had already discontinued these agents.
 

Continue RAS inhibitors in advanced CKD for best outcomes

Dr. Bhandari and colleagues note that in a large observational trial published in January 2021, Swedish researchers found an increase in the incidence of major cardiovascular events and death among patients with advanced CKD who had discontinued RAS inhibitors.

But they observe, “Our trial did not have sufficient power to investigate the effect of the discontinuation of RAS inhibitors on cardiovascular events or mortality. However, because our findings are consistent with a lack of advantage for such discontinuation with respect to kidney function, there is little rationale to conduct a larger randomized trial to investigate cardiovascular safety.”

“Our findings do not support the hypothesis that the discontinuation of RAS inhibitors in patients with advanced and progressive chronic kidney disease would improve kidney function, quality of life, or exercise capacity.”

“The results of this trial will inform future clinical practice worldwide and guideline recommendations,” they conclude.

STOP ACEi received no commercial funding. Dr. Bhandari has reported no relevant financial relationships.

A low-carbohydrate diet appears to be an effective weight-loss intervention in liver transplant recipients with obesity as compared with a calorie-restrictive diet, according to interim findings presented at the annual meeting of the American Association for the Study of Liver Diseases.

In particular, the intervention showed significant improvements in the metabophenotype profile, including visceral adipose tissue and abdominal subcutaneous adipose tissue, said Mohammad Siddiqui, MD, a gastroenterologist and liver transplant specialist at Virginia Commonwealth University, Richmond.

“Weight gain and obesity after liver transplantation is common,” he said. “Posttransplant obesity is associated with increased cardiometabolic risk burden, increased risk of cardiovascular disease and mortality, and overall mortality.”

Previously, Dr. Siddiqui and colleagues have shown that posttransplant weight loss is difficult because of metabolic inflexibility and mitochondrial inefficiency. By specifically targeting carbohydrate utilization, metabolic flexibility could be restored in liver transplant recipients, he noted.

Dr. Siddiqui and colleagues conducted a randomized controlled trial of 27 adult liver transplant recipients with obesity for 24 weeks. The primary endpoint was change in weight, and the secondary endpoints involved metabophenotype, metabolic flexibility, mitochondrial function, and metabolic risk. The research team excluded patients with end-stage disease, terminal disease, use of weight-loss medications, pregnancy, or uncontrolled psychiatric illness that could interfere with adherence.

Among the participants, 13 were randomized to a calorie restrictive diet of less than 1,200-1,500 calories per day, and 14 were randomized to a low-carbohydrate diet of 20 grams or less per day. At enrollment, the participants underwent dietary, activity, skeletal muscle, and body composition assessments, as well as metabophenotype measurements of visceral adipose tissue, abdominal subcutaneous adipose tissue, muscle fat infiltration, fat-free muscle volume, and proton density fat fraction.

All participants were advised to maintain the same level of physical activity, which was measured through 7-day accelerometry. In addition, the patients were contacted every 2 weeks throughout the 24-week study period.

“We wanted to reinforce the dietary advice. We wanted to identify factors that may lead to compliance,” Dr. Siddiqui said. “Multiple studies have documented that the more contact that patients have during weight-loss studies with medical personnel, the more effective those strategies are.”

Overall, the dietary interventions were well tolerated, and neither group showed a significant change in renal function.

The average weight loss was –7.6 kg over 6 months in the low-carbohydrate group, as compared with –0.6 kg in the calorie-restrictive group.

The low carbohydrate diet also positively affected participants’ metabophenotype profile, particularly fat deposits. As compared with the calorie-restrictive group, the low-carbohydrate group showed statistically significant improvements in visceral adipose tissue, abdominal subcutaneous adipose tissue, and muscle fat infiltration.

The liver proton density fat fraction, which is associated with fatty liver disease, decreased by 0.53% in the low-carbohydrate group and increased by 0.46% in the calorie-restrictive group, but the difference didn’t reach statistical significance.

The fat-free muscle volume decreased by about 5% in the low-carbohydrate group. Dr. Siddiqui noted that the researchers don’t know yet whether this translates to a decrease in muscle function.

In terms of metabolic risk, the low-carbohydrate diet did not affect serum lipids (such as triglycerides or cholesterol measures), renal function (such as serum creatinine, glomerular filtration rate, or blood urea nitrogen), or insulin resistance (through glucose or hemoglobin A1c). At the same time, among patients taking insulin at the time of enrollment, about 90% of patients randomized to the low-carbohydrate group were able to reduce insulin to zero during the study.

Upon completion of the current study, Dr. Siddiqui and colleagues hope to provide foundational safety and efficacy data for carbohydrate restriction in liver transplant recipients. In the ongoing study, the researchers are further investigating the dietary intervention impacts on metabolic flexibility, skeletal muscle mitochondrial function, atherogenic lipoproteins, and vascular function.

“Are we actually, on a molecular level, fixing the fundamental problem that liver transplant recipients have to improve outcomes?” he said. “We’re doing very detailed profiling of these patients, so we will have data that shows how this actually affects them.”

Dr. Siddiqui was asked about the sustainability of the low-carbohydrate diet, particularly with a restrictive parameter of 20 grams per day. During the COVID-19 pandemic, Dr. Siddiqui noted, the study was slowed and the research team was able to collect follow-up data.

“Surprisingly, we have a high rate of compliance, even after 6 months of therapy, and I think this has to do with a patient population that’s been through cirrhosis and has almost died,” he said. “They’re far more compliant, and we’re seeing that. We’re also changing the physiology and improving mitochondrial function, which improves the weight loss and weight maintenance, though I don’t know how long that’s going to last.”

The study sponsorship was not disclosed. Dr. Siddiqui reported no relevant conflicts of interest.
 

A low-carbohydrate diet appears to be an effective weight-loss intervention in liver transplant recipients with obesity as compared with a calorie-restrictive diet, according to interim findings presented at the annual meeting of the American Association for the Study of Liver Diseases.

In particular, the intervention showed significant improvements in the metabophenotype profile, including visceral adipose tissue and abdominal subcutaneous adipose tissue, said Mohammad Siddiqui, MD, a gastroenterologist and liver transplant specialist at Virginia Commonwealth University, Richmond.

“Weight gain and obesity after liver transplantation is common,” he said. “Posttransplant obesity is associated with increased cardiometabolic risk burden, increased risk of cardiovascular disease and mortality, and overall mortality.”

Previously, Dr. Siddiqui and colleagues have shown that posttransplant weight loss is difficult because of metabolic inflexibility and mitochondrial inefficiency. By specifically targeting carbohydrate utilization, metabolic flexibility could be restored in liver transplant recipients, he noted.

Dr. Siddiqui and colleagues conducted a randomized controlled trial of 27 adult liver transplant recipients with obesity for 24 weeks. The primary endpoint was change in weight, and the secondary endpoints involved metabophenotype, metabolic flexibility, mitochondrial function, and metabolic risk. The research team excluded patients with end-stage disease, terminal disease, use of weight-loss medications, pregnancy, or uncontrolled psychiatric illness that could interfere with adherence.

Among the participants, 13 were randomized to a calorie restrictive diet of less than 1,200-1,500 calories per day, and 14 were randomized to a low-carbohydrate diet of 20 grams or less per day. At enrollment, the participants underwent dietary, activity, skeletal muscle, and body composition assessments, as well as metabophenotype measurements of visceral adipose tissue, abdominal subcutaneous adipose tissue, muscle fat infiltration, fat-free muscle volume, and proton density fat fraction.

All participants were advised to maintain the same level of physical activity, which was measured through 7-day accelerometry. In addition, the patients were contacted every 2 weeks throughout the 24-week study period.

“We wanted to reinforce the dietary advice. We wanted to identify factors that may lead to compliance,” Dr. Siddiqui said. “Multiple studies have documented that the more contact that patients have during weight-loss studies with medical personnel, the more effective those strategies are.”

CHICAGO – Systematic mortality-risk assessment of patients who presented to hospital emergency departments for acute heart failure led to better patient outcomes in a controlled Canadian trial with more than 5,000 patients.

Thirty days after patients presented, the incidence of death from any cause or hospitalization for cardiovascular causes – one of two primary endpoints in the COACH study – was 12.1% among patients who underwent acute risk assessment and 14.5% in control patients who did not undergo this assessment, which translated into an adjusted, significant 12% relative risk reduction for the patients who underwent systematic assessment, Douglas S. Lee, MD, PhD, said at the American Heart Association scientific sessions.

Mitchel L. Zoler/MDedge News

The study’s second primary endpoint, the incidence of the same combined outcome 20 months after initial presentation, was 54.4% among the 2,480 patients assessed with the risk-assessment tool and 56.2% in the 2,972 controls, a significant, adjusted relative risk reduction of 5%.

This benefit was primarily driven by reductions in cardiovascular hospitalizations, which fell by an adjusted 16% in the intervention group compared with controls, and more specifically by hospitalizations for heart failure, which tallied a relative 20% less with the intervention. Both were significant between-group differences.

The other portion of the combined endpoint, all-cause mortality, was not significantly different between the patients who underwent the systematic emergency department assessment and the controls who were managed using usual emergency-department protocols.

Simultaneous with the report, the results also appeared online in the New England Journal of Medicine.
 

A pathway for early discharge and improved outcomes

“Implementation of this approach may lead to a pathway for early discharge from the hospital or emergency department, and improved patient outcomes,” said Dr. Lee, a professor at the University of Toronto, and a senior core scientist at the ICES Cardiovascular Research Program in Toronto.

Mitchel L. Zoler/MDedge News

“The treatment effect on the primary process outcome – patients admitted or discharged – will add useful insights into how intervention may improve,” commented Harriette Van Spall, MD, who was designated discussant for the report. The findings “fill an important knowledge gap,” added Dr. Van Spall, a cardiologist at McMaster University in Hamilton, Ont. The results “have important implications for health resource utilization,” she said.

The risk assessment tool used in the study is called the Emergency Heart failure Mortality Risk Grade for 30-day mortality (EHMRG30-ST), which was devised and validated by Dr. Lee and his associates. The assessment tool uses 11 clinical variables that include age, systolic blood pressure, heart rate, oxygen saturation, potassium and creatinine levels, and presence of ST depression on a 12-lead ECG.

The study design recommended that patients be discharged early and receive standardized transitional care as outpatients if they had a low risk of death within 7 days and within 30 days as estimated by the EHMRG30-ST. The protocol recommended that patients scored as high risk should be admitted to the hospital, and that clinicians use their clinical judgment for intermediate-risk patients but favor admission for intermediate to high risk and discharge for low to intermediate risk. The study ran at 10 hospitals in Ontario. Initially, all 10 hospitals assessed patients by usual care, and then, over time, each hospital began using the tool so that by the end of the study all 10 hospitals employed it. Among the 2,480 patients seen during the active phase, 2,442 actually underwent assessment, with 24% rated as low risk, 32% rated as intermediate risk, and 44% judged to have high risk.

The researchers also ran risk assessments retrospectively on the controls, who showed a roughly similar risk distribution, with 18% low risk, 28% intermediate risk, and 54% high risk.

The patients averaged 78 years of age, 55% were men, about 40% had diabetes, and about 64% had a prior heart failure diagnosis.



Heart failure admissions have become ‘a big deal’

Emergency department clinicians and heart failure cardiologists “have worked together for a long time” when making decisions about which patients with acute heart failure need hospital admission, commented Mary N. Walsh, MD, medical director of the heart failure and cardiac transplantation programs at Ascension St. Vincent Heart Center in Indianapolis. These decisions “became a big deal” a decade ago when the U.S. Centers for Medicare & Medicaid Services launched the Hospital Readmissions Reduction Program that began to penalize hospitals for high rates of hospital readmissions for several conditions including heart failure, she said in an interview.

Mitchel L. Zoler/MDedge News

“If a heart failure patient is not admitted, they can’t be readmitted,” Dr. Walsh noted.

“Many risk-assessment tools exist for patients once they are hospitalized, but these tools have not been used in emergency departments. The take-home message is that we need to start risk assessment sooner, in the emergency department,” she said.

But the specific approach tested in the COACH trial needs more study and may need further tweaking to work in the United States, where it is not clear who would pay for a program like the one tested in the trial. Canada’s unified health care payment system makes the COACH approach more financially feasible, Dr. Walsh commented.

COACH received no commercial funding. Dr. Lee, Dr. Van Spall, and Dr. Walsh had no disclosures.

In the first transplant of a genetically altered pig heart into a human in January, initial unexpected, prolonged ECG readings apparently did not affect the heart’s function, although the organ suddenly began to fail at day 50.

A study of these ECG changes, scheduled for presentation by Calvin Kagan, MD, and colleagues at the American Heart Association scientific sessions, offers insight into this novel operation.

As widely reported, the patient, 57-year-old David Bennett of Maryland, had end-stage heart disease and was a poor candidate for a ventricular assist device and was ineligible for a human heart, when he consented to be the first human to be transplanted with a pig heart that had a number of genes added or subtracted with the goal, in part, to prevent rejection.

University of Maryland Medical Center

The heart initially performed well after it was transplanted in an operation at the University of Maryland School of Medicine (UMSOM) in Baltimore on Jan. 7, but failed in the second month, and Mr. Bennett died on March 9.

The Food and Drug Administration had granted emergency authorization for the surgery through its expanded access (compassionate use) program, coauthor Muhammad Mohiuddin, MD, said in an interview.

“We have learned a lot and hope we can do more,” said Dr. Mohiuddin, scientific and program director of the cardiac xenotransplantation program at UMSOM.

“Suddenly on day 50, the heart started to get thicker and was not relaxing enough,” explained senior author Timm-Michael Dickfeld, MD, PhD, director of electrophysiology research at UMSOM. A biopsy revealed substantial buildup of interstitial fluid that restricted movement. The fluid was replaced by fibrous tissue, leading to irreversible damage.

Persistent, prolonged ECG parameters

In the heart from a genetically modified pig, three genes associated with antibody-mediated rejection and a gene associated with pig heart tissue growth had been inactivated and six human genes associated with immune acceptance had been added. The donor pig was supplied by Revivicor (Blacksburg, Va.).

The patient’s immunosuppressant therapy included an experimental antirejection medication (Kiniksa Pharmaceuticals; Lexington, Mass.).  

The patient had daily 12-lead ECGs after the transplant.

In prior research using a pig heart transplanted into a pig body, ECG readings showed a short PR interval (50-120 ms), short QRS duration (70-90 ms) and short QT intervals (260-380 ms).

However, in the transplanted xenograft heart, the initial ECG readings showed a longer PR interval of 190 ms, QRS duration of 138 ms, and QT of 538 ms.

Prolonged intrinsic PR intervals remained stable during the postoperative course (210 ms, range 142-246 ms).

QRS duration also remained prolonged (145 ms, range 116-192 ms), but shortened during the postoperative course (days 21-40 vs. 41-60: 148 ms vs. 132 ms; P < .001).

Increased QT persisted (509 ms, range 384-650 ms) with dynamic fluctuations. The shortest QT duration was observed on day 14 (P < .001).

“In a human heart, when those parameters get longer, this can indicate signs of electrical or myocardial disease,” Dr. Dickfeld explained in a press release from the AHA.

“The QRS duration may prolong when, for example, the muscle and the electrical system itself is diseased, and that is why it takes a long time for electricity to travel from cell to cell and travel from one side of the heart to the other,” he said.

“In the human heart, the QT duration is correlated with an increased risk of abnormal heart rhythms,” he noted. “In our patient, it was concerning that the QT measure was prolonged. While we saw some fluctuations, the QT measure remained prolonged during the whole 61 days.”
 

‘Interesting study’

Two experts who were not involved with this research weighed in on the findings for this news organization.

“This very interesting study reinforces the difficulties in xenotransplantation, and the need for more research to be able to safely monitor recipients, as baseline values are unknown,” said Edward Vigmond, PhD.

Dr. Vigmond, from the Electrophysiology and Heart Modeling Institute at the University of Bordeaux in France, published a related study about a model of translation of pig to human electrophysiology.

The ECG is sensitive to the electrical activation pattern of the heart, along with the cellular and tissue electrical properties, he noted.

“Although pigs and humans may be similar in size, there are many differences between them,” Dr. Vigmond observed, including “the extent of the rapid conduction system of the heart, the number of nuclei in the muscle cells, the proteins in the cell membrane which control electrical activity, the orientation of the heart and thorax, and the handling of calcium inside the cell.”

“On top of this,” he continued, “donor hearts are denervated, so they no longer respond to nervous modulation, and circulating compounds in the blood which affect heart function vary between species.

“With all these differences, it is not surprising that the ECG of a pig heart transplanted into a human resembles neither that of a human nor that of a pig,” Dr. Vigmond said.

“It is interesting to note that the humanized-gene-edited porcine heart exhibited abnormal electrical conduction parameters from the outset,” said Mandeep R. Mehra, MD.

“Whether these changes were due to the gene modifications (i.e., already inherent in the pig ECG prior to transplant) or a result of the transplant operation challenges (such as the ischemia reperfusion injury and early immunological interactions) is uncertain and should be clarified,” said Dr. Mehra, of Harvard Medical School and Brigham and Women’s Medicine in Boston.

“Knowledge of these changes is important to determine whether a simple ECG parameter may be useful to identify changes that could indicate developing pathology,” Dr. Mehra added.

“In the older days of human transplantation, we often used ECG parameters such as a change in voltage amplitude to identify signals for rejection,” he continued. “Whether such changes occurred in this case could be another interesting aspect to explore as changes occurred in cardiac performance in response to the physiological and pathological challenges that were encountered in this sentinel case.”

The study authors reported having no outside sources of funding.

As widely reported, the patient, 57-year-old David Bennett of Maryland, had end-stage heart disease and was a poor candidate for a ventricular assist device and was ineligible for a human heart, when he consented to be the first human to be transplanted with a pig heart that had a number of genes added or subtracted with the goal, in part, to prevent rejection.

The heart initially performed well after it was transplanted in an operation at the University of Maryland School of Medicine (UMSOM) in Baltimore on Jan. 7, but failed in the second month, and Mr. Bennett died on March 9.

The Food and Drug Administration had granted emergency authorization for the surgery through its expanded access (compassionate use) program, coauthor Muhammad Mohiuddin, MD, said in an interview.

“We have learned a lot and hope we can do more,” said Dr. Mohiuddin, scientific and program director of the cardiac xenotransplantation program at UMSOM.

“Suddenly on day 50, the heart started to get thicker and was not relaxing enough,” explained senior author Timm-Michael Dickfeld, MD, PhD, director of electrophysiology research at UMSOM. A biopsy revealed substantial buildup of interstitial fluid that restricted movement. The fluid was replaced by fibrous tissue, leading to irreversible damage.

Persistent, prolonged ECG parameters

In the heart from a genetically modified pig, three genes associated with antibody-mediated rejection and a gene associated with pig heart tissue growth had been inactivated and six human genes associated with immune acceptance had been added. The donor pig was supplied by Revivicor (Blacksburg, Va.).

The patient’s immunosuppressant therapy included an experimental antirejection medication (Kiniksa Pharmaceuticals; Lexington, Mass.).  

The patient had daily 12-lead ECGs after the transplant.

In prior research using a pig heart transplanted into a pig body, ECG readings showed a short PR interval (50-120 ms), short QRS duration (70-90 ms) and short QT intervals (260-380 ms).

However, in the transplanted xenograft heart, the initial ECG readings showed a longer PR interval of 190 ms, QRS duration of 138 ms, and QT of 538 ms.

Prolonged intrinsic PR intervals remained stable during the postoperative course (210 ms, range 142-246 ms).

QRS duration also remained prolonged (145 ms, range 116-192 ms), but shortened during the postoperative course (days 21-40 vs. 41-60: 148 ms vs. 132 ms; P < .001).

Increased QT persisted (509 ms, range 384-650 ms) with dynamic fluctuations. The shortest QT duration was observed on day 14 (P < .001).

“In a human heart, when those parameters get longer, this can indicate signs of electrical or myocardial disease,” Dr. Dickfeld explained in a press release from the AHA.

“The QRS duration may prolong when, for example, the muscle and the electrical system itself is diseased, and that is why it takes a long time for electricity to travel from cell to cell and travel from one side of the heart to the other,” he said.

“In the human heart, the QT duration is correlated with an increased risk of abnormal heart rhythms,” he noted. “In our patient, it was concerning that the QT measure was prolonged. While we saw some fluctuations, the QT measure remained prolonged during the whole 61 days.”
 

‘Interesting study’

Two experts who were not involved with this research weighed in on the findings for this news organization.

“This very interesting study reinforces the difficulties in xenotransplantation, and the need for more research to be able to safely monitor recipients, as baseline values are unknown,” said Edward Vigmond, PhD.

Dr. Vigmond, from the Electrophysiology and Heart Modeling Institute at the University of Bordeaux in France, published a related study about a model of translation of pig to human electrophysiology.

The ECG is sensitive to the electrical activation pattern of the heart, along with the cellular and tissue electrical properties, he noted.

“Although pigs and humans may be similar in size, there are many differences between them,” Dr. Vigmond observed, including “the extent of the rapid conduction system of the heart, the number of nuclei in the muscle cells, the proteins in the cell membrane which control electrical activity, the orientation of the heart and thorax, and the handling of calcium inside the cell.”

“On top of this,” he continued, “donor hearts are denervated, so they no longer respond to nervous modulation, and circulating compounds in the blood which affect heart function vary between species.

“With all these differences, it is not surprising that the ECG of a pig heart transplanted into a human resembles neither that of a human nor that of a pig,” Dr. Vigmond said.

“It is interesting to note that the humanized-gene-edited porcine heart exhibited abnormal electrical conduction parameters from the outset,” said Mandeep R. Mehra, MD.

“Whether these changes were due to the gene modifications (i.e., already inherent in the pig ECG prior to transplant) or a result of the transplant operation challenges (such as the ischemia reperfusion injury and early immunological interactions) is uncertain and should be clarified,” said Dr. Mehra, of Harvard Medical School and Brigham and Women’s Medicine in Boston.

“Knowledge of these changes is important to determine whether a simple ECG parameter may be useful to identify changes that could indicate developing pathology,” Dr. Mehra added.

“In the older days of human transplantation, we often used ECG parameters such as a change in voltage amplitude to identify signals for rejection,” he continued. “Whether such changes occurred in this case could be another interesting aspect to explore as changes occurred in cardiac performance in response to the physiological and pathological challenges that were encountered in this sentinel case.”

The study authors reported having no outside sources of funding.

The U.S. Centers for Disease Control and Prevention has released updated and expanded recommendations for prescribing opioids for adults with acute and chronic pain not related to cancer, sickle cell disease, or palliative/end-of-life care.

The 2022 Clinical Practice Guideline provides guidance on determining whether to initiate opioids for pain; selecting opioids and determining opioid dosages; deciding duration of initial opioid prescription and conducting follow-up; and assessing risk and addressing potential harms of opioid use.

“Patients with pain should receive compassionate, safe, and effective pain care. We want clinicians and patients to have the information they need to weigh the benefits of different approaches to pain care, with the goal of helping people reduce their pain and improve their quality of life,” Christopher M. Jones, PharmD, DrPH, acting director for the CDC’s National Center for Injury Prevention and Control, said in a news release.
 

How to taper safely

The last guideline on the topic was released by CDC in 2016. Since then, new evidence has emerged regarding the benefits and risks of prescription opioids for acute and chronic pain, comparisons with nonopioid pain treatments, dosing strategies, opioid dose-dependent effects, risk mitigation strategies, and opioid tapering and discontinuation, the CDC says.

A “critical” addition to the 2022 guideline is advice on tapering opioids, Dr. Jones said during a press briefing.

“Practical tips on how to taper in an individualized patient-centered manner have been added to help clinicians if the decision is made to taper opioids, and the guideline explicitly advises against abrupt discontinuation or rapid dose reductions of opioids,” Dr. Jones said.

“That is based on lessons learned over the last several years as well as new science about how we approach tapering and the real harms that can result when patients are abruptly discontinued or rapidly tapered,” he added.

The updated guideline was published online Nov. 3 in the Morbidity and Mortality Weekly Report.

Key recommendations in the 100-page document include the following:

• In determining whether or not to initiate opioids, nonopioid therapies are at least as effective as opioids for many common types of acute pain. Use of nondrug and nonopioid drug therapies should be maximized as appropriate, and opioid therapy should only be considered for acute pain if it is anticipated that benefits outweigh risks to the patient.
• Before starting opioid therapy, providers should discuss with patients the realistic benefits and known risks of opioid therapy.
• Before starting ongoing opioid therapy for patients with subacute pain lasting 1 to 3 months or chronic pain lasting more than 3 months, providers should work with patients to establish treatment goals for pain and function, and consideration should be given as to how opioid therapy will be discontinued if benefits do not outweigh risks.
• Once opioids are started, the lowest effective dose of immediate-release opioids should be prescribed for no longer than needed for the expected duration of pain severe enough to require opioids.
• Within 1 to 4 weeks of starting opioid therapy for subacute or chronic pain, providers should work with patients to evaluate and carefully weigh benefits and risks of continuing opioid therapy; care should be exercised when increasing, continuing, or reducing opioid dosage.
• Before starting and periodically during ongoing opioid therapy, providers should evaluate risk for opioid-related harms and should work with patients to incorporate relevant strategies to mitigate risk, including offering naloxone and reviewing potential interactions with any other prescribed medications or substance used.
• Abrupt discontinuation of opioids should be avoided, especially for patients receiving high doses.
• For treating patients with opioid use disorder, treatment with evidence-based medications should be provided, or arrangements for such treatment should be made.

Dr. Jones emphasized that the guideline is “voluntary and meant to guide shared decision-making between a clinician and patient. It’s not meant to be implemented as absolute limits of policy or practice by clinicians, health systems, insurance companies, governmental entities.”

He also noted that the “current state of the overdose crisis, which is very much driven by illicit synthetic opioids, is not the aim of this guideline.

“The release of this guideline is really about advancing pain care and improving the lives of patients living with pain,” he said.

“We know that at least 1 in 5 people in the country have chronic pain. It’s one of the most common reasons why people present to their health care provider, and the goal here is to advance pain care, function, and quality of life for that patient population, while also reducing misuse, diversion, and consequences of prescription opioid misuse,” Dr. Jones added.

Sexual activity in older adults is something of a taboo, rarely discussed and largely ignored by researchers.

But failing to address human sexuality in old age can lead doctors to ask seniors the wrong questions about sex – if they ask at all.

When researchers do look at the issue, they find surprises, as Janie Steckenrider, PhD, has learned. In a new study presented at the annual scientific meeting of the Gerontological Society of America, Dr. Steckenrider, a professor of political science at Loyola Marymount University, Los Angeles, found that previous attempts to qualify the sexual activities of seniors appear to be limited largely to partnered sex – despite the fact that many older people tend to practice “solo sex,” another term for masturbation.

“Maybe they don’t have a partner, or their partner has sexual dysfunction, or has died. There could be pain involved,” Dr. Steckenrider said. “In the hierarchy of sexual activity, penetrative sex is the cultural norm. As people get older, penetrative sex becomes less important. The hierarchy shifts to include more emotional intimacy like touching and fondling.”

Of the 17 survey questionnaires Dr. Steckenrider analyzed, 11 had questions that focused exclusively on sex with a partner. Nine defined sexual activity and just five included questions about masturbation.

Take, for example, a 2018 poll by researchers at the University of Michigan, Ann Arbor, who found that 40% of people ages 65-80 said they were sexually active. Meanwhile, nearly two thirds of older adults said they were interested in sex, and more than half said sex was important to their quality of life.

But Dr. Steckenrider said this poll, like others, left the term “sexually active” undefined – raising questions about the meaning of the findings.

Sheryl A. Kingsberg, PhD, chief of behavioral medicine in the department of obstetrics and gynecology at University Hospitals Cleveland Medical Center, said she was surprised so few of the studies analyzed by Dr. Steckenrider included masturbation in their definition of sex. 

“Clinical trials of potential treatments for female sexual problems, like hypoactive sexual desire disorder or painful sex, include both definitions of sexual activity and questions about masturbation, she said. “Definitions also should not assume partnered sex is male or female,” she added. 

Dr. Steckenrider and Dr. Kingsberg encouraged healthcare providers to address the sexual health of their patients by asking questions about their sexual health and concerns. 

“Health care professionals cannot address sexual concerns if they don’t acknowledge their patients as sexual beings and inquire about sexual problems,” Dr. Kingsberg said.

The key, according to Dr. Steckenrider, is for clinicians to ask the right questions. But which ones?  

Detail is crucial. 

“I think that’s far better than asking whether they are sexually active, yes or no,” she said. “Ask: ‘How often have you engaged in these types of sexual activities?’ If you are looking for frequency, and be specific about the types of sex: kissing, fondling, or masturbation.”
