TOPLINE: 

A study comparing the clinical reasoning of an artificial intelligence (AI) model with that of physicians found the AI outperformed residents and attending physicians in simulated cases. The AI had more instances of incorrect reasoning than the doctors did but scored better overall.

METHODOLOGY:

• The study involved 39 physicians from two academic medical centers in Boston and the generative AI model GPT-4.
• Participants were presented with 20 simulated clinical cases involving common problems such as pharyngitis, headache, abdominal pain, cough, and chest pain. Each case included sections describing the triage presentation, review of systems, physical examination, and diagnostic testing.
• The primary outcome was the Revised-IDEA (R-IDEA) score, a 10-point scale evaluating clinical reasoning documentation across four domains: Interpretive summary, differential diagnosis, explanation of the lead diagnosis, and alternative diagnoses.

TAKEAWAY: 

• AI achieved a median R-IDEA score of 10, higher than attending physicians (median score, 9) and residents (8).
• The chatbot had a significantly higher estimated probability of achieving a high R-IDEA score of 8-10 (0.99) compared with attendings (0.76) and residents (0.56).
• AI provided more responses that contained instances of incorrect clinical reasoning (13.8%) than residents (2.8%) and attending physicians (12.5%). It performed similarly to physicians in diagnostic accuracy and inclusion of cannot-miss diagnoses.

IN PRACTICE:

“Future research should assess clinical reasoning of the LLM-physician interaction, as LLMs will more likely augment, not replace, the human reasoning process,” the authors of the study wrote. 

SOURCE:

Adam Rodman, MD, MPH, with Beth Israel Deaconess Medical Center, Boston, was the corresponding author on the paper. The research was published online in JAMA Internal Medicine. 

LIMITATIONS: 

Simulated clinical cases may not replicate performance in real-world scenarios. Further training could enhance the performance of the AI, so the study may underestimate its capabilities, the researchers noted. 

DISCLOSURES:

The study was supported by the Harvard Clinical and Translational Science Center and Harvard University. Authors disclosed financial ties to publishing companies and Solera Health. Dr. Rodman received funding from the Gordon and Betty Moore Foundation.

In last month’s column, I discussed employees who are “clock watchers” and how to address this issue in your practice if it exists. Here’s another scenario you may encounter from the Office Politics Forum at the recent American Academy of Dermatology annual meeting:

A 40-year-old dermatologist has practiced in the same office since residency and is loved by patients and staff. He remained with the practice through its takeover by a local hospital three years previously. Recently, over a 3-month period, everyone in the office notices a change in this dermatologist’s behavior. He no longer appears happy, is argumentative with staff and patients alike, often dismisses patients’ concerns, and calls in sick during the practice’s busiest days.

It is not difficult to recognize these changes as hallmarks of burnout, which continues to be pervasive across all practice settings and specialties. According to the American Medical Association’s National Burnout Benchmarking report, over 50% of physicians report some characteristics of burnout, which include emotional exhaustion, depersonalization, and a feeling of decreased personal achievement.

Addressing physician burnout requires a systems-based approach that targets these root causes at all levels, from individual coping strategies to organizational and systemic changes in the healthcare industry. Here are some strategies that have worked for me and others:

Optimize Practice Efficiency: This is the consistent theme of this column over several decades: Streamline office processes to enhance the quality of care while reducing unnecessary workload. This can involve adopting efficient patient scheduling systems, improving clinic flow, and utilizing technology like patient portals judiciously to avoid increasing the task load without compensation.

Promote Work-Life Balance: Encourage a culture that values work-life balance. This can include flexible scheduling, respecting off-duty hours by limiting non-emergency work communications, and using your vacation time. Remember Eastern’s First Law: Your last words will NOT be, “I wish I had spent more time in the office.”

Implement Medical Scribes: I’ve written frequently about this, including a recent column on the new artificial intelligence (AI) scribes, such as DeepCura, DeepScribe, Nuance, Suki, Augmedix, Tali AI, Iodine Software, ScribeLink, and Amazon Web Services’ new HealthScribe product. Utilizing medical scribes to handle documentation can significantly reduce the administrative burden, allowing physicians to focus more on patient care rather than paperwork, potentially improving both physician and patient satisfaction. (As always, I have no financial interest in any product or service mentioned in this column.)

Provide Professional Development Opportunities: Offer opportunities for professional growth and development. This can include attending conferences, participating in research, or providing time and resources for continuing education. Such opportunities can reinvigorate a physician’s passion for medicine and improve job satisfaction.

Foster a Supportive Work Environment: Create a supportive work culture where staff and physicians feel comfortable discussing challenges and seeking support. Regular meetings or check-ins can help identify early signs of burnout and address them proactively.

Evaluate and Adjust Workloads: Regularly assess physician workloads to ensure they are manageable. Adjusting patient loads, redistributing tasks among team members, or hiring additional staff can help prevent burnout.

Leadership Training and Support: Provide training for leaders within the practice on recognizing signs of burnout and effective management strategies. Supportive leadership is crucial in creating an environment where physicians feel valued and heard.

Peer Support and Mentorship Programs: Establish peer support or mentorship programs where physicians can share experiences, offer advice, and provide emotional support to each other.

Feedback and Continuous Improvement: Managers should regularly solicit feedback from physicians regarding their workload, job satisfaction, and suggestions for improvements. Actively work on implementing feasible changes to address concerns.

TOPLINE:

In patients with polycystic ovary syndrome (PCOS), laser and light therapies, alone or in combination with pharmacological agents, improve hirsutism and psychological well-being in women, according to the results of a systematic review.

METHODOLOGY:

• Hirsutism, which affects 70%-80% of women with PCOS, is frequently marginalized as a cosmetic issue by healthcare providers, despite its significant psychological repercussions, including diminished self-esteem, reduced quality of life, and heightened depression.
• The 2023 international evidence-based PCOS guideline considers managing hirsutism a priority in women with PCOS.
• Researchers reviewed six studies (four randomized controlled trials and two cohort studies), which included 423 patients with PCOS who underwent laser or light-based hair reduction therapies, published through 2022.
• The studies evaluated the alexandrite laser, diode laser, and intense pulsed light (IPL) therapy, with and without pharmacological treatments. The main outcomes were hirsutism severity, psychological outcome, and adverse events.

TAKEAWAY:

• Alexandrite laser (wavelength, 755 nm) showed effective hair reduction and improved patient satisfaction (one study); high-fluence treatment yielded better outcomes than low-fluence treatment (one study). Alexandrite laser 755 nm also showed longer hair-free intervals and greater hair reduction than IPL therapy at 650-1000 nm (one study).
• Combined IPL (600 nm) and metformin therapy improved hirsutism and hair count reduction compared with IPL alone, but with more side effects (one study).
• Diode laser treatments (810 nm) with combined oral contraceptives improved hirsutism and related quality of life measures compared with diode laser alone or with metformin (one study).
• Comparing two diode lasers (wavelengths, 810 nm), low-fluence, high repetition laser showed superior hair width reduction and lower pain scores than high fluence, low-repetition laser (one study).

IN PRACTICE:

Laser and light treatments alone or combined with other treatments have demonstrated “encouraging results in reducing hirsutism severity, enhancing psychological well-being, and improving overall quality of life for affected individuals,” the authors wrote, noting that additional high-quality trials evaluating these treatments, which include more patients with different skin tones, are needed.

SOURCE:

The first author of the review is Katrina Tan, MD, Monash Health, Department of Dermatology, Melbourne, Victoria, Australia, and it was published online in JAMA Dermatology.

LIMITATIONS:

Limitations include low certainty of evidence because of the observational nature of some of the studies, the small number of studies, and underrepresentation of darker skin types, limiting generalizability.

DISCLOSURES:

The review is part of an update to the PCOS guideline, which was funded by the Australian National Health and Medical Research Council through various organizations. Several authors reported receiving grants and personal fees outside this work. Dr. Tan was a member of the 2023 PCOS guideline evidence team. Other authors declared no conflicts of interest.

Results from a preliminary clinical trial demonstrated the obesity drug, tirzepatide, effectively treated obstructive sleep apnea (OSA), according to information sent to investors of the pharmaceutical company, Eli Lilly.

Indiana-based Eli Lilly sells tirzepatide under the brand name Zepbound, which was approved by the FDA in November to treat overweight and obesity. Tirzepatide is also marketed under the name Mounjaro to treat diabetes, and it’s among the same class of drugs as other well-known weight loss and diabetes drugs like Ozempic and Wegovy.

The newly announced results came from a pair of studies that followed people with moderate to severe OSA who also had obesity. People in the study took tirzepatide, which is given by injection, for one year. One study evaluated people who were using CPAP during sleep, and another study included people who didn’t use the device. People in both studies taking tirzepatide had significant reductions in sleep events and also lost about 20% of body weight. About 70% of people in the studies were men.

The findings have not yet been published in a peer-reviewed medical journal, and the preliminary results were announced by Eli Lilly because of reporting requirements related to information that could affect stock prices. The company indicated that detailed results will be presented at a conference of the American Diabetes Association in June and will be submitted to a peer-reviewed journal for consideration of publication. The company also plans to submit the information to the FDA for approval consideration mid-year, the investor news release stated.

People in the study taking tirzepatide on average experienced 63% fewer instances of reduced oxygen due to breathing changes, or events when breathing entirely stopped, Eli Lilly reported.

A sleep expert from Washington University in St. Louis told The New York Times the initial findings were extremely positive and noted that tirzepatide works to treat the underlying cause of sleep apnea, rather than current treatments that just address symptoms.

Tirzepatide “is a great alternative for people who are obese and can’t use CPAP or are on CPAP and want to improve the effect,” Eric Landsness, MD, PhD, told The New York Times. 

Eli Lilly indicated the most commonly reported adverse events in the studies were diarrhea, nausea, vomiting, and constipation.

An estimated 39 million people have OSA and about 33 million people use CPAP machines, according to The National Council on Aging. The condition has been increasingly diagnosed in recent years and becomes more likely to affect people as they get older.

Here’s a new direction for smartphones in healthcare. 

Researchers from the National Institute of Standards and Technology (NIST), Boulder, Colorado, say a smartphone compass could be used to analyze biomarkers in body fluids — blood, sweat, urine, or saliva — to monitor or diagnose disease.

“We’re just at this point demonstrating this new way of sensing that we hope [will be] very accessible and very portable,” said Gary Zabow, PhD, a group leader in the applied physics division at NIST who supervised the research. 

In a proof-of-concept study, the researchers measured glucose levels in sangria, pinot grigio, and champagne. The detection limit reached micromolar concentrations — on par with or better than some widely used glucose sensors, such as continuous glucose monitors. They also accurately measured the pH levels of coffee, orange juice, and root beer.

More tests are needed to confirm the method works in biological fluids, so it could be a while before it’s available for clinical or commercial use. 

Still, the prospect is “exciting,” said Aydogan Ozcan, PhD, a bioengineering professor at the University of California, Los Angeles, who was not involved in the study. “It might enable new capabilities for advanced sensing applications in field settings or even at home.”

The advance builds on growing research using smartphones to put powerful medical devices in patients’ hands. A new AI-powered app can use a smartphone camera to detect skin cancer, while other apps administer cognitive tests to detect dementia. Smartphone cameras can even be harnessed for “advanced optical microscopes and sensors to the level where we could even see and detect individual DNA molecules with inexpensive optical attachments,” Dr. Ozcan said. More than six billion people worldwide own a smartphone.

The compass inside smartphones is a magnetometer — it measures magnetic fields. Normally it detects the earth’s magnetic fields, but it can also detect small, nearby magnets and changes in those magnets’ positions. 

The researchers embedded a small magnet inside a strip of “smart hydrogel — a piece of material that expands or contracts” when immersed in a solution, said Dr. Zabow.

As the hydrogel gets bigger or smaller, it moves the magnet, Dr. Zabow explained. For example, if the hydrogel is designed to expand when the solution is acidic or contract when it’s basic, it can move the magnet closer or farther from the phone’s magnetometer, providing an indicator of pH. For glucose, the hydrogel expands or contracts depending on the concentration of sugar in the liquid.

With some calibration and coding to translate that reading into a number, “you can effectively read out glucose or pH,” Dr. Zabow said.

Only a small strip of hydrogel is needed, “like a pH test strip that you use for a pool,” said first study author Mark Ferris, PhD, a postdoctoral researcher at NIST. 

Like a pool pH test strip, this test is meant to be “easy to use, and at that kind of price,” Dr. Ferris said. “It’s supposed to be something that’s cheap and disposable.” Each pH hydrogel strip is about 3 cents, and glucose strips are 16 cents, Dr. Ferris estimated. In bulk, those prices could go down.

Next the team plans to test the strips with biological fluids. But complex fluids like blood could pose a challenge, as other molecules present could react with the strip and affect the results. “It may be that you need to tweak the chemistry of the hydrogel to make sure it is really specific to one biomolecule and there is no interference from other biomolecules,” Dr. Zabow said.

The technique could be adapted to detect other biomarkers or molecules, the researchers said. It could also be used to check for chemical contaminants in tap, lake, or stream water.

The photo of the patient’s foot, sent from his campsite, included a cheeky note: “I remember you telling me that getting in trouble doing something was better than getting in trouble doing nothing. This lets me get out there and know that I have feedback.”

The “this” was the patient’s “foot selfie,” an approach that allows patients at a risk for diabetic foot ulcers (DFUs) to snap a picture and send it to their healthcare providers for evaluation.

This particular patient had an extensive history of previous wounds. Some had essentially kept him house-bound in the past, as he was afraid to get another one.

This time, however, he got an all-clear to keep on camping, “and we scheduled him in on the following Tuesday [for follow-up],” said the camper’s physician David G. Armstrong, DPM, MD, PhD, professor of surgery and neurological surgery, USC Keck School of Medicine, Los Angeles.

Dr. Armstrong is one of the researchers evaluating the concept of foot selfies. It’s a welcome advance, he and others said, and has been shown to help heal wounds and reverse pre-ulcer lesions. Research on foot selfies continues, but much more is needed to solve the issue of DFUs, diabetic foot infections (DFIs), and the high rates of reinfection, experts know.

Worldwide, about 18.6 million people have a DFU each year, including 1.6 million in the United States. About 50%-60% of ulcers become infected, with 20% of moderate to severe infections requiring amputation of the limb. The 5-year mortality rate for DFUs is 30%, but it climbs to 70% after amputation. While about 40% of ulcers heal within 12 weeks, 42% recur at the 1-year mark, setting up a vicious and costly cycle. Healthcare costs for patients with diabetes and DFUs are five times as high as costs for patients with diabetes but no DFUs. The per capita cost to treat a DFU in America is $17,500.

While the statistics paint a grim picture, progress is being made on several fronts:

• US Food and Drug Administration (FDA) guidance on the development of drugs for DFUs, under evaluation, is forthcoming.
• New treatments are under study.
• A multidisciplinary team approach is known to improve outcomes.

Anatomy of a DFU

When neuropathy develops in those with diabetes, they no longer have what Dr. Armstrong calls the “gift” of pain perception. “They can wear a hole in their foot like you and I wear a hole in our sock or shoe,” he said. “That hole is called a diabetic foot ulcer.”

A DFU is an open wound on the foot, often occurring when bleeding develops beneath a callus and then the callus wears away. Deeper tissues of the foot are then exposed.

About half of the DFUs get infected, hence the FDA guidance, said Dr. Armstrong, who is also founding president of the American Limb Preservation Society, which aims to eliminate preventable amputations within the next generation. Every 20 seconds, Dr. Armstrong said, someone in the world loses a leg due to diabetes.
 

FDA Guidance on Drug Development for DFIs

In October, the FDA issued draft guidance for industry to articulate the design of clinical trials for developing antibacterial drugs to treat DFIs without concomitant bone and joint involvement. Comments closed on December 18. Among the points in the guidance, which is nonbinding, are to include DFIs of varying depths and extent in phase 3 trials and ideally to include only those patients who have not had prior antibacterial treatment for the current DFI.

According to an FDA spokesperson, “The agency is working to finalize the guidance. However, a timeline for its release has not yet been established.”

The good news about the upcoming FDA guidance, Dr. Armstrong said, is that the agency has realized the importance of treating the infections. Fully one third of direct costs of care for diabetes are spent on the lower extremities, he said. Keeping patients out of the hospital, uninfected, and “keeping legs on bodies” are all important goals, he said.

Pharmaceutical firms need to understand that “you aren’t dealing with a normal ulcer,” said Andrew J.M. Boulton, MD, professor of medicine at the University of Manchester and physician consultant at the Manchester Royal Infirmary, Manchester, England, and a visiting professor at the University of Miami. For research, “the most important thing is to take account of off-loading the ulcers,” he said. “Most ulcers will heal if put in a boot.”

Dr. Boulton, like Dr. Armstrong, a long-time expert in the field, contended that pharma has not understood this concept and has wasted millions over the last three decades doing studies that were poorly designed and controlled.
 

Treatments: Current, Under Study

Currently, DFIs are treated with antimicrobial therapy, without or without debridement, along with a clinical assessment for ischemia. If ischemia is found, care progresses to wound care and off-loading devices, such as healing sandals. Clinicians then assess the likelihood of improved outcomes with revascularization based on operative risks and distribution of lower extremity artery disease and proceed depending on the likelihood. If osteomyelitis testing shows it is present, providers proceed to wound debridement, limb-sparing amputation, and prolonged antimicrobials, as needed.

More options are needed, Dr. Armstrong said.

Among the many approaches under study:

• DFUs can be accurately detected by applying artificial intelligence to the “foot selfie” images taken by patients on smartphones, research by Dr.  and  has found.
• After a phase 3 study of  for DFUs originally intending to enroll 300 subjects was discontinued because of slow patient recruitment, an interim analysis was conducted on 44 participants. It showed a positive trend toward wound closure in the group receiving the injected gene therapy, VM202 (ENGENSIS), in their calf muscles. VM202 is a plasmid DNA-encoding human hepatocyte growth factor. While those in both the intervention and placebo groups showed wound-closing effects at month 6, in 23 patients with neuro-ischemic ulcers, the percentage of those reaching complete closure of the DFU was significantly higher in the treated group at months 3, 4, and 5 (P = .0391, .0391, and .0361, respectively). After excluding two outliers, the difference in months 3-6 became more significant (P = .03).
• An closed more DFUs than standard care after 12 weeks — 70% vs 34% (P = .00032). Of the 100 participants randomized, 50 per group, 42% of the treatment group and 56% of the control group experienced adverse events, with eight withdrawn due to serious adverse events (such as osteomyelitis).
• A closed more refractory DFUs over a 16-week study than standard sharp debridement, with 65% of water-treated ulcers healed but just 42% of the standard care group (P = .021, unadjusted).
• Researchers from UC Davis and VA Northern California Healthcare are evaluating timolol, a beta adrenergic receptor blocker already approved for topical administration for glaucoma, as a way to heal chronic DFUs faster. After demonstrating that the medication worked in animal models, researchers then launched a study to use it off-label for DFUs. While data are still being analyzed, researcher Roslyn (Rivkah) Isseroff, MD, of UC Davis and VA, said that data so far demonstrate that the timolol reduced transepidermal water loss in the healed wounds, and that is linked with a decrease in re-ulceration.

The Power of a Team

Multidisciplinary approaches to treatment are effective in reducing amputation, with one review of 33 studies finding the approach worked to decrease amputation in 94% of them. “The American Limb Preservation Society (ALPS) lists 30 programs,” said Dr. Armstrong, the founding president of the organization. “There may be as many as 100.”

Team compositions vary but usually include at least one medical specialty clinician, such as infectious disease, primary care, or endocrinology, and two or more specialty clinicians, such as vascular, podiatric, orthopedic, or plastic surgery. A shoe specialist is needed to prescribe and manage footwear. Other important team members include nutrition experts and behavioral health professionals to deal with associated depression.

Johns Hopkins’ Multidisciplinary Diabetic Foot and Wound Service launched in 2012 and includes vascular surgeons, surgical podiatrists, endocrinologists, wound care nurses, advanced practice staff, board-certified wound care specialists, orthopedic surgeons, infection disease experts, physical therapists, and certified orthotists.

“This interdisciplinary care model has been repeatedly validated by research as superior for limb salvage and wound healing,” said Nestoras Mathioudakis, MD, codirector of the service. “For instance, endocrinologists and diabetes educators are crucial for managing uncontrolled diabetes — a key factor in infection and delayed wound healing. Similarly, vascular surgeons play a vital role in addressing peripheral arterial disease to improve blood flow to the affected area.”

“Diabetic foot ulcers might require prolonged periods of specialized care, including meticulous wound management and off-loading, overseen by surgical podiatrists and wound care experts,” he said. “In cases where infection is present, particularly with multidrug resistant organisms or when standard antibiotics are contraindicated, the insight of an infectious disease specialist is invaluable.”

While the makeup of teams varies from location to location, he said “the hallmark of effective teams is their ability to comprehensively manage glycemic control, foot wounds, vascular disease, and infections.”

The power of teams, Dr. Armstrong said, is very much evident after his weekly “foot selfie rounds” conducted Mondays at 7 AM, with an “all feet on deck” approach. “Not a week goes by when we don’t stop a hospitalization,” he said of the team evaluating the photos, due to detecting issues early, while still in the manageable state.

Teams can trump technology, Dr. Armstrong said. A team of just a primary care doctor and a podiatrist can make a significant reduction in amputations, he said, just by a “Knock your socks off” approach. He reminds primary care doctors that observing the feet of their patients with diabetes can go a long way to reducing DFUs and the hospitalizations and amputations that can result.

Dr. Mathioudakis and Dr. Isseroff reported no disclosures. Dr. Boulton consults for Urgo Medical, Nevro Corporation, and AOT, Inc. Dr. Armstrong reported receiving consulting fees from Podimetrics; Molnlycke; Cardiovascular Systems, Inc.; Endo Pharmaceuticals; and Averitas Pharma (GRT US).

The good news about the upcoming FDA guidance, Dr. Armstrong said, is that the agency has realized the importance of treating the infections. Fully one third of direct costs of care for diabetes are spent on the lower extremities, he said. Keeping patients out of the hospital, uninfected, and “keeping legs on bodies” are all important goals, he said.

Pharmaceutical firms need to understand that “you aren’t dealing with a normal ulcer,” said Andrew J.M. Boulton, MD, professor of medicine at the University of Manchester and physician consultant at the Manchester Royal Infirmary, Manchester, England, and a visiting professor at the University of Miami. For research, “the most important thing is to take account of off-loading the ulcers,” he said. “Most ulcers will heal if put in a boot.”

Dr. Boulton, like Dr. Armstrong, a long-time expert in the field, contended that pharma has not understood this concept and has wasted millions over the last three decades doing studies that were poorly designed and controlled.
 

Treatments: Current, Under Study

Currently, DFIs are treated with antimicrobial therapy, without or without debridement, along with a clinical assessment for ischemia. If ischemia is found, care progresses to wound care and off-loading devices, such as healing sandals. Clinicians then assess the likelihood of improved outcomes with revascularization based on operative risks and distribution of lower extremity artery disease and proceed depending on the likelihood. If osteomyelitis testing shows it is present, providers proceed to wound debridement, limb-sparing amputation, and prolonged antimicrobials, as needed.

More options are needed, Dr. Armstrong said.

Among the many approaches under study:

• DFUs can be accurately detected by applying artificial intelligence to the “foot selfie” images taken by patients on smartphones, research by Dr.  and  has found.
• After a phase 3 study of  for DFUs originally intending to enroll 300 subjects was discontinued because of slow patient recruitment, an interim analysis was conducted on 44 participants. It showed a positive trend toward wound closure in the group receiving the injected gene therapy, VM202 (ENGENSIS), in their calf muscles. VM202 is a plasmid DNA-encoding human hepatocyte growth factor. While those in both the intervention and placebo groups showed wound-closing effects at month 6, in 23 patients with neuro-ischemic ulcers, the percentage of those reaching complete closure of the DFU was significantly higher in the treated group at months 3, 4, and 5 (P = .0391, .0391, and .0361, respectively). After excluding two outliers, the difference in months 3-6 became more significant (P = .03).
• An closed more DFUs than standard care after 12 weeks — 70% vs 34% (P = .00032). Of the 100 participants randomized, 50 per group, 42% of the treatment group and 56% of the control group experienced adverse events, with eight withdrawn due to serious adverse events (such as osteomyelitis).
• A closed more refractory DFUs over a 16-week study than standard sharp debridement, with 65% of water-treated ulcers healed but just 42% of the standard care group (P = .021, unadjusted).
• Researchers from UC Davis and VA Northern California Healthcare are evaluating timolol, a beta adrenergic receptor blocker already approved for topical administration for glaucoma, as a way to heal chronic DFUs faster. After demonstrating that the medication worked in animal models, researchers then launched a study to use it off-label for DFUs. While data are still being analyzed, researcher Roslyn (Rivkah) Isseroff, MD, of UC Davis and VA, said that data so far demonstrate that the timolol reduced transepidermal water loss in the healed wounds, and that is linked with a decrease in re-ulceration.

The Power of a Team

Multidisciplinary approaches to treatment are effective in reducing amputation, with one review of 33 studies finding the approach worked to decrease amputation in 94% of them. “The American Limb Preservation Society (ALPS) lists 30 programs,” said Dr. Armstrong, the founding president of the organization. “There may be as many as 100.”

Team compositions vary but usually include at least one medical specialty clinician, such as infectious disease, primary care, or endocrinology, and two or more specialty clinicians, such as vascular, podiatric, orthopedic, or plastic surgery. A shoe specialist is needed to prescribe and manage footwear. Other important team members include nutrition experts and behavioral health professionals to deal with associated depression.

Johns Hopkins’ Multidisciplinary Diabetic Foot and Wound Service launched in 2012 and includes vascular surgeons, surgical podiatrists, endocrinologists, wound care nurses, advanced practice staff, board-certified wound care specialists, orthopedic surgeons, infection disease experts, physical therapists, and certified orthotists.

“This interdisciplinary care model has been repeatedly validated by research as superior for limb salvage and wound healing,” said Nestoras Mathioudakis, MD, codirector of the service. “For instance, endocrinologists and diabetes educators are crucial for managing uncontrolled diabetes — a key factor in infection and delayed wound healing. Similarly, vascular surgeons play a vital role in addressing peripheral arterial disease to improve blood flow to the affected area.”

“Diabetic foot ulcers might require prolonged periods of specialized care, including meticulous wound management and off-loading, overseen by surgical podiatrists and wound care experts,” he said. “In cases where infection is present, particularly with multidrug resistant organisms or when standard antibiotics are contraindicated, the insight of an infectious disease specialist is invaluable.”

While the makeup of teams varies from location to location, he said “the hallmark of effective teams is their ability to comprehensively manage glycemic control, foot wounds, vascular disease, and infections.”

The power of teams, Dr. Armstrong said, is very much evident after his weekly “foot selfie rounds” conducted Mondays at 7 AM, with an “all feet on deck” approach. “Not a week goes by when we don’t stop a hospitalization,” he said of the team evaluating the photos, due to detecting issues early, while still in the manageable state.

Teams can trump technology, Dr. Armstrong said. A team of just a primary care doctor and a podiatrist can make a significant reduction in amputations, he said, just by a “Knock your socks off” approach. He reminds primary care doctors that observing the feet of their patients with diabetes can go a long way to reducing DFUs and the hospitalizations and amputations that can result.

Dr. Mathioudakis and Dr. Isseroff reported no disclosures. Dr. Boulton consults for Urgo Medical, Nevro Corporation, and AOT, Inc. Dr. Armstrong reported receiving consulting fees from Podimetrics; Molnlycke; Cardiovascular Systems, Inc.; Endo Pharmaceuticals; and Averitas Pharma (GRT US).

TOPLINE:

Less than 7 hours of sleep per night is common in individuals with type 1 diabetes (T1D) but is tied to poor cardiometabolic health, particularly in adolescents.

METHODOLOGY:

• Sleep is recognized as an important factor in diabetes assessment and treatment by the 2023 American Diabetes Association’s Standards of Medical Care in Diabetes, but it is unclear whether sleep may improve health outcomes across the lifespan in patients with T1D.
• This secondary analysis of the BCQR-T1D crossover trial investigated the link between sleep and cardiometabolic health in 42 adults (age, 19-60 years) and 42 adolescents (age, 12-18 years) with T1D.
• Participants had T1D duration greater than 9 months and received bromocriptine quick-release (BCQR) therapy or placebo for 4 weeks and then switched between the treatments in a separate 4-week period.
• They underwent laboratory testing and anthropometric measurements. Also, continuous glucose monitoring data were collected for a week during each treatment phase along with an accompanying insulin dosing diary.
• Participants were required to wear an actigraphy monitor on the wrist of their nondominant hand for 7 days during each treatment phase to estimate sleep duration.

TAKEAWAY:

• Most adolescents (62%) and adults (74%) with T1D reported less than 7 hours of sleep at baseline.
• Participants with insufficient sleep versus those without insufficient sleep (< 7 vs > 7 hours) had a larger waist circumference and higher mean body mass index, systolic blood pressure, and pulse pressure, as well as lower estimated insulin sensitivity and brachial artery distensibility (P < .05 for all).
• When stratified by age, only adolescents with T1D with insufficient sleep had significant differences in most health outcomes by sleep duration status, except that adults with less than 7 hours of sleep had higher pulse pressure than those with more than 7 hours of sleep.
• Compared with placebo, BCQR slightly improved sleeping parameters in adolescents by delaying their time of waking up and prolonging their time in bed.

IN PRACTICE:

“Sleep may be an important and novel target for improving health in individuals with T1D, particularly when initiated in adolescence or early in diabetes,” the authors wrote.

SOURCE:

Stacey L. Simon, PhD, and Janet K. Snell-Bergeon, PhD, University of Colorado Anschutz Medical Campus, Aurora, led this study, which was published online in Diabetes, Obesity and Metabolism.

LIMITATIONS:

The study lacked polysomnography or melatonin assessment to quantify circadian rhythms and subjective sleep quality ratings. It also had no objective measurement of the timing of the daily pills of BCQR, which, when taken in the morning, are hypothesized to reset the circadian rhythm for hypothalamic dopamine and serotonin. The recommended sleep duration of 8 hours for adolescents was not used as the cutoff value due to too few participants who qualified. Also, this study›s findings may be affected by the fact that participants were recruited throughout the year, while adolescents show different sleeping patterns during the academic year compared with school breaks.

DISCLOSURES:

This work was supported by a JDRF grant. Two authors declared receiving equipment, honoraria for lectures, and support for conference travel, which were all unrelated to this study.

Physician practice ownership by corporations, including health insurers, private equity firms, and large pharmacy chains, reached 30.1% as of January for the first time surpassing ownership by hospitals and health systems (28.4%), according to a new report.

As a result, about three in five physician practices are now owned by nonphysicians.

In early 2020, corporations owned just about 17% of US medical practices, while hospitals and health systems owned about 25%, according to the report released Thursday by nonprofit Physician Advocacy Institute (PAI). But corporate ownership of medical groups surged during the pandemic.

These trends raise questions about how best to protect patients and physicians in a changing employment landscape, said Kelly Kenney, PAI’s chief executive officer, in a statement.

“Corporate entities are assuming control of physician practices and changing the face of medicine in the United States with little to no scrutiny from regulators,” Ms. Kenney said.

The research, conducted by consulting group Avalere for PAI, used the IQVIA OneKey database that contains physician and practice location information on hospital and health system ownership.

By 2022-2023, there was a 7.3% increase in the percentage of practices owned by hospitals and 5.9% increase in the percentage of physicians employed by these organizations, PAI said. In the same time frame, there was an 11% increase in the percentage of practices owned by corporations and a 3.0% increase in the percentage of physicians employed by these entities.

“Physicians have an ethical responsibility to their patients’ health,” Ms. Kenney said. “Corporate entities have a fiduciary responsibility to their shareholders and are motivated to put profits first…these interests can conflict with providing the best medical care to patients.”
 

Federal Scrutiny Increases

However, both federal and state regulators are paying more attention to what happens to patients and physicians when corporations acquire practices.

“Given recent trends, we are concerned that some transactions may generate profits for those firms at the expense of patients’ health, workers’ safety, quality of care, and affordable healthcare for patients and taxpayers,” said the Federal Trade Commission (FTC) and the Justice (DOJ) and Health and Human Services (HHS) departments.

This statement appears in those agencies’ joint request for information (RFI) announced in March. An RFI is a tool that federal agencies can use to gauge the level of both support and opposition they would face if they were to try to change policies. Public comments are due May 6.

Corporations and advocacy groups often submit detailed comments outlining reasons why the federal government should or should not act on an issue. But individuals also can make their case in this forum.

The FTC, DOJ, and HHS are looking broadly at consolidation in healthcare, but they also spell out potential concerns related to acquisition of physician practices.

For example, they asked clinicians and support staff to provide feedback about whether acquisitions lead to changes in:

• Take-home pay
• Staffing levels
• Workplace safety
• Compensation model (eg, from fixed salary to volume based)
• Policies regarding patient referrals
• Mix of patients
• The volume of patients
• The way providers practice medicine (eg, incentives, prescribing decisions, forced protocols, restrictions on time spent with patients, or mandatory coding practices)
• Administrative or managerial organization (eg, transition to a management services organization).

When I was doing my nephrology training, I had an attending who would write notes that were, well, kind of funny. I remember one time we were seeing a patient whose first name was “Lucky.” He dryly opened his section of the consult note as follows: “This is a 56-year-old woman with an ironic name who presents with acute renal failure.”

As an exhausted renal fellow, I appreciated the bit of color amid the ongoing series of tragedies that was the consult service. But let’s be clear — writing like this in the medical record is not a good idea. It wasn’t a good idea then, when any record might end up disclosed during a malpractice suit, and it’s really not a good idea now, when patients have ready and automated access to all the notes we write about them.

And yet, worse language than that of my attending appears in hospital notes all the time; there is research about this. Specifically, I’m talking about language that does not have high clinical utility but telegraphs the biases of the person writing the note. This is known as “stigmatizing language” and it can be overt or subtle.

For example, a physician wrote “I listed several fictitious medication names and she reported she was taking them.”

This casts suspicions about the patient’s credibility, as does the more subtle statement, “he claims nicotine patches don’t work for him.” Stigmatizing language may cast the patient in a difficult light, like this note: “she persevered on the fact that ... ‘you wouldn’t understand.’ ”

This stuff creeps into our medical notes because doctors are human, not AI — at least not yet — and our frustrations and biases are real. But could those frustrations and biases lead to medical errors? Even deaths? Stay with me.

We are going to start by defining a very sick patient population: those admitted to the hospital and who, within 48 hours, have either been transferred to the intensive care unit or died. Because of the severity of illness in this population we’ve just defined, figuring out whether a diagnostic or other error was made would be extremely high yield; these can mean the difference between life and death.

In a letter appearing in JAMA Internal Medicine, researchers examined a group of more than 2300 patients just like this from 29 hospitals, scouring the medical records for evidence of these types of errors.

Nearly one in four (23.2%) had at least one diagnostic error, which could include a missed physical exam finding, failure to ask a key question on history taking, inadequate testing, and so on.

Understanding why we make these errors is clearly critical to improving care for these patients. The researchers hypothesized that stigmatizing language might lead to errors like this. For example, by demonstrating that you don’t find a patient credible, you may ignore statements that would help make a better diagnosis.

Just over 5% of these patients had evidence of stigmatizing language in their medical notes. Like earlier studies, this language was more common if the patient was Black or had unstable housing.

Critically, stigmatizing language was more likely to be found among those who had diagnostic errors — a rate of 8.2% vs 4.1%. After adjustment for factors like race, the presence of stigmatizing language was associated with roughly a doubling of the risk for diagnostic errors.

Now, I’m all for eliminating stigmatizing language from our medical notes. And, given the increased transparency of all medical notes these days, I expect that we’ll see less of this over time. But of course, the fact that a physician doesn’t write something that disparages the patient does not necessarily mean that they don’t retain that bias. That said, those comments have an effect on all the other team members who care for that patient as well; it sets a tone and can entrench an individual’s bias more broadly. We should strive to eliminate our biases when it comes to caring for patients. But perhaps the second best thing is to work to keep those biases to ourselves.

As an exhausted renal fellow, I appreciated the bit of color amid the ongoing series of tragedies that was the consult service. But let’s be clear — writing like this in the medical record is not a good idea. It wasn’t a good idea then, when any record might end up disclosed during a malpractice suit, and it’s really not a good idea now, when patients have ready and automated access to all the notes we write about them.

And yet, worse language than that of my attending appears in hospital notes all the time; there is research about this. Specifically, I’m talking about language that does not have high clinical utility but telegraphs the biases of the person writing the note. This is known as “stigmatizing language” and it can be overt or subtle.

For example, a physician wrote “I listed several fictitious medication names and she reported she was taking them.”

This casts suspicions about the patient’s credibility, as does the more subtle statement, “he claims nicotine patches don’t work for him.” Stigmatizing language may cast the patient in a difficult light, like this note: “she persevered on the fact that ... ‘you wouldn’t understand.’ ”

This stuff creeps into our medical notes because doctors are human, not AI — at least not yet — and our frustrations and biases are real. But could those frustrations and biases lead to medical errors? Even deaths? Stay with me.

We are going to start by defining a very sick patient population: those admitted to the hospital and who, within 48 hours, have either been transferred to the intensive care unit or died. Because of the severity of illness in this population we’ve just defined, figuring out whether a diagnostic or other error was made would be extremely high yield; these can mean the difference between life and death.

In a letter appearing in JAMA Internal Medicine, researchers examined a group of more than 2300 patients just like this from 29 hospitals, scouring the medical records for evidence of these types of errors.

Nearly one in four (23.2%) had at least one diagnostic error, which could include a missed physical exam finding, failure to ask a key question on history taking, inadequate testing, and so on.

Understanding why we make these errors is clearly critical to improving care for these patients. The researchers hypothesized that stigmatizing language might lead to errors like this. For example, by demonstrating that you don’t find a patient credible, you may ignore statements that would help make a better diagnosis.

Just over 5% of these patients had evidence of stigmatizing language in their medical notes. Like earlier studies, this language was more common if the patient was Black or had unstable housing.

Critically, stigmatizing language was more likely to be found among those who had diagnostic errors — a rate of 8.2% vs 4.1%. After adjustment for factors like race, the presence of stigmatizing language was associated with roughly a doubling of the risk for diagnostic errors.

Now, I’m all for eliminating stigmatizing language from our medical notes. And, given the increased transparency of all medical notes these days, I expect that we’ll see less of this over time. But of course, the fact that a physician doesn’t write something that disparages the patient does not necessarily mean that they don’t retain that bias. That said, those comments have an effect on all the other team members who care for that patient as well; it sets a tone and can entrench an individual’s bias more broadly. We should strive to eliminate our biases when it comes to caring for patients. But perhaps the second best thing is to work to keep those biases to ourselves.

TOPLINE:

Biscuits reformulated with the sweeteners and sweetness enhancers (S&SEs) neotame and stevia rebaudioside M (StRebM) yield appetite responses similar to those of sucrose-sweetened ones but decrease post-meal insulin and glucose levels in adults with overweight or obesity.

METHODOLOGY:

• In 2023, the World Health Organization issued a conditional recommendation that S&SE should not be used for weight control, apparently due to a lack of evidence for a clear benefit and weak evidence linking S&SE intake with excess weight and poorer health outcomes.
• This randomized crossover trial, conducted in England and France between 2021 and 2022, evaluated the acute (1 day) and repeated (daily for 2 weeks) effects of S&SEs vs sucrose in solid food on appetite and endocrine responses in adults with overweight or obesity.
• Overall, 53 adults (33 women, 20 men; aged 18-60 years) with overweight or obesity consumed biscuits with fruit filling containing either sucrose or reformulated with the S&SEs StRebM or neotame, daily for three 2-week intervention periods separated by a washout period of 14-21 days.
• Participants were required to fast for 12 hours before attending a laboratory session at the beginning (day 1) and end (day 14) of each consumption period.
• The primary endpoint was the composite appetite score, while secondary endpoints included food preferences, postprandial glucose and insulin response, and other satiety-related peptides, such as ghrelin, glucagon-like peptide 1, and pancreatic polypeptide.

TAKEAWAY:

• The composite appetite scores were comparable between the sucrose, StRebM, and neotame groups, with lower appetite suppression observed on day 14 than on day 1 for all three formulations.
• Neotame (P < .001) and StRebM (P < .001) lowered postprandial insulin levels compared with sucrose, while glucose levels saw a decline only with StRebM (and not with neotame) compared with sucrose (P < .05).
• The S&SEs had no effect on satiety levels, as any acute or repeated exposures to StRebM or neotame vs sucrose did not affect the ghrelin and glucagon-like peptide-1 responses.
• Gastrointestinal issues were more frequently reported in the neotame and StRebM groups than in the sucrose group.

IN PRACTICE:

“There is no detrimental impact of replacing sugar with S&SE in these endpoints,” the authors wrote. “Additionally, glucose and insulin responses were blunted after acute and repeated consumption of S&SE-reformulated biscuits, which may confer a benefit for blood glucose control, for example, in individuals at risk of developing type 2 diabetes.”

SOURCE:

This study was led by Catherine Gibbons, School of Psychology, Faculty of Medicine and Health, University of Leeds, England. It was published online in eBioMedicine.

LIMITATIONS:

The reformulated products required the addition of polyol bulking agents (8% maltitol and 8% sorbitol) to match the biscuits in sensory qualities as closely as possible. Gastrointestinal symptoms (initial bloating and flatulence) in the neotame and StRebM formulations may be due to the polyols, classed as low-digestible carbohydrates.

DISCLOSURES:

This study received funding from a European Union Horizon 2020 program, SWEET (Sweeteners and sweetness enhancers: Impact on health, obesity, safety, and sustainability). The authors reported receiving funding and honoraria from the food and beverage industry and trade groups from various entities.
