Establishing a Hospital Artificial Intelligence Committee to Improve Patient Care
In the past 10 years, artificial intelligence (AI) applications have exploded in numerous fields, including medicine. Myriad publications report that the use of AI in health care is increasing, and AI has shown utility in many medical specialties, eg, pathology, radiology, and oncology.1,2
In cancer pathology, AI was able not only to detect various cancers, but also to subtype and grade them. In addition, AI could predict survival, the success of therapeutic response, and underlying mutations from histopathologic images.3 In other medical fields, AI applications are as notable. For example, in imaging specialties like radiology, ophthalmology, dermatology, and gastroenterology, AI is being used for image recognition, enhancement, and segmentation. In addition, AI is beneficial for predicting disease progression, survival, and response to therapy in other medical specialties. Finally, AI may help with administrative tasks like scheduling.
However, many obstacles to successfully implementing AI programs in the clinical setting exist, including clinical data limitations and ethical use of data, trust in the AI models, regulatory barriers, and lack of clinical buy-in due to insufficient basic AI understanding.2 To address these barriers to successful clinical AI implementation, we decided to create a formal governing body at James A. Haley Veterans’ Hospital in Tampa, Florida. Accordingly, the hospital AI committee charter was officially approved on July 22, 2021. Our model could be used by both US Department of Veterans Affairs (VA) and non-VA hospitals throughout the country.
AI Committee
The vision of the AI committee is to improve outcomes and experiences for our veterans by developing trustworthy AI capabilities to support the VA mission. The mission is to build robust capacity in AI to create and apply innovative AI solutions and transform the VA by facilitating a learning environment that supports the delivery of world-class benefits and services to our veterans. Our vision and mission are aligned with the VA National AI Institute. 4
The AI Committee comprises 7 subcommittees: ethics, AI clinical product evaluation, education, data sharing and acquisition, research, 3D printing, and improvement and innovation. The role of the ethics subcommittee is to ensure the ethical and equitable implementation of clinical AI. We created the ethics subcommittee guidelines based on the World Health Organization ethics and governance of AI for health documents.5 They include 6 basic principles: protecting human autonomy; promoting human well-being and safety and the public interest; ensuring transparency, explainability, and intelligibility; fostering responsibility and accountability; ensuring inclusiveness and equity; and promoting AI that is responsive and sustainable (Table 1).
As the name indicates, the role of the AI clinical product evaluation subcommittee is to evaluate commercially available clinical AI products. More than 400 US Food and Drug Administration–approved AI medical applications exist, and the list is growing rapidly. Most AI applications are in medical imaging like radiology, dermatology, ophthalmology, and pathology.6,7 Each clinical product is evaluated according to 6 principles: relevance, usability, risks, regulatory, technical requirements, and financial (Table 2).8 We are in the process of evaluating a few commercial AI algorithms for pathology and radiology, using these 6 principles.
Implementations
After a comprehensive evaluation, we implemented 2 ClearRead (Riverain Technologies) AI radiology solutions. ClearRead CT Vessel Suppress produces a secondary series of computed tomography (CT) images, suppressing vessels and other normal structures within the lungs to improve nodule detectability, and ClearRead Xray Bone Suppress, which increases the visibility of soft tissue in standard chest X-rays by suppressing the bone on the digital image without the need for 2 exposures.
The role of the education subcommittee is to educate the staff about AI and how it can improve patient care. Every Friday, we email an AI article of the week to our practitioners. In addition, we publish a newsletter, and we organize an annual AI conference. The first conference in 2022 included speakers from the National AI Institute, Moffitt Cancer Center, the University of South Florida, and our facility.
As the name indicates, the data sharing and acquisition subcommittee oversees preparing data for our clinical and research projects. The role of the research subcommittee is to coordinate and promote AI research with the ultimate goal of improving patient care.
Other Technologies
Although 3D printing does not fall under the umbrella of AI, we have decided to include it in our future-oriented AI committee. We created an online 3D printing course to promote the technology throughout the VA. We 3D print organ models to help surgeons prepare for complicated operations. In addition, together with our colleagues from the University of Florida, we used 3D printing to address the shortage of swabs for COVID-19 testing. The VA Sunshine Healthcare Network (Veterans Integrated Services Network 8) has an active Innovation and Improvement Committee. 9 Our improvement and innovation subcommittee serves as a coordinating body with the network committee .
Conclusions
Through the hospital AI committee, we believe that we may overcome many obstacles to successfully implementing AI applications in the clinical setting, including the ethical use of data, trust in the AI models, regulatory barriers, and lack of clinical buy-in due to insufficient basic AI knowledge.

HCV reinfection uncommon among people who inject drugs
The findings, which are based on prospective data from 13 countries, including the United States, and were published in Annals of Internal Medicine (2022 Aug 8. doi: 10.7326/M21-4119), should encourage physicians to treat HCV in people with a history of injection drug use, said lead author Jason Grebely, PhD. They should also pressure payers to lift reimbursement restrictions on the same population.
“Direct-acting antiviral medications for HCV infection are safe and effective among people receiving OAT and people with recent injecting-drug use,” the investigators wrote. “Concerns remain, however, that HCV reinfection may reduce the benefits of cure among people who inject drugs and compromise HCV elimination efforts.”
They explored these concerns through a 3-year extension of the phase 3 CO-STAR trial that evaluated elbasvir and grazoprevir in people consistently taking OAT. Participants in the CO-STAR trial, which had a 96% sustained virologic response rate among those who completed therapy, could elect to participate in the present study, offering a prospective look at long-term reinfection.
Out of 296 participants in the CO-STAR trial, 286 were evaluable for reinfection and 199 enrolled in the present extension. The majority were White (79.4%) and male (75.9%), with most taking methadone (79%), followed by buprenorphine (20%). At 6 months, 40 out of 191 respondents (21%) reported injection-drug use in the previous month. At the 3-year mark, 26 out of 142 respondents (18%) disclosed injection-drug use in the previous month.
For all participants in the CO-STAR trial, the overall rate of reinfection at 3 years was 1.7 per 100 person-years (95% confidence interval, 0.8-3.0), which is lower than the rate reported in systematic reviews (3.8 per 100 person-years), according to the investigators.
In the extension analysis, the 3-year reinfection rate was lower still, at 1.2 per 100 person-years. The rate was slightly higher among people who reported injection-drug use in the previous month (1.9 per 100 person-years), and slightly lower among those who did not report injection-drug use in the prior month (0.5 per 100 person-years). More pronounced differences in reinfection were observed among participants who shared needles (6.4 per 100 person-years), versus those who didn’t share needles (1.5 per 100 person years).
Low reinfection rate may help facilitate removal of reimbursement restrictions
“Most of the reinfections in this study occurred within 24 weeks of completing treatment, suggesting that this is a key period for optimizing treatment of opioid use disorder and for providing access to needle and syringe programs that have documented benefits in preventing HCV transmission,” the investigators wrote.
This is one of the largest observational studies of its kind to date, bolstered by “excellent study retention” and a “well-characterized cohort,” with findings that should prompt real-world action, said Dr. Grebely, who is head of the hepatitis C and drug use group in the viral hepatitis clinical research program at the Kirby Institute, University of New South Wales, Sydney.
“Given that reinfection has often been cited ... by some providers as a reason for not offering treatment to people receiving OAT, the low reinfection rate in this study will be incredibly important for guiding practice and ensuring therapy is not withheld from this group,” Dr. Grebely said in an interview. “In terms of policy implications, these data may also help to facilitate the removal of reimbursement restrictions based on recent drug/alcohol use criteria that are in place among many payers in the United States.”
More research needed to determine optimal intervention strategies
Carl Latkin, PhD, professor and vice chair of the department of health, behavior, and society at Johns Hopkins University, Baltimore, called the present publication a “great article and well-done study with long-term follow-up.”
Dr. Latkin, who investigates biobehavioral interventions for disadvantaged communities, said the reported rate of reinfection is “very low among a group of current and former injectors.”
Affirming Dr. Grebely’s call for supportive practices by physicians and payers, Dr. Latkin said: “The study highlights the importance of improving access to medication for opioid use disorder. This level of treatment adherence in this group is much higher than for many other medications. Given these data, it would be difficult for payers to have a rational reason for blanket restrictions for HCV treatment among people who use drugs.”
Dr. Latkin explained that “it isn’t simply injection drug use per se” that drives HCV reinfection; instead, he cited social factors, such as lack of housing, as well as withdrawal symptoms, especially among those without access to medications for opioid use disorder (MOUD).
Dr. Latkin and Grebely also agreed that more research is needed to determine optimal intervention strategies.
Dr. Grebely called for one to enhance HCV testing and linkage to care, a topic he covered in a recent review article (Lancet Gastroenterol Hepatol. 2022 May;7[5]:426-45.).
Dr. Latkin said that, while it’s clear that “syringe services programs, accessible HCV treatment, and MOUD are needed,” it is unclear how much coverage is necessary for a given population.
Findings support critical nature of needle and syringe exchange programs
Sarah M. Kattakuzhy, MD, an associate professor in the division of clinical care & research at the Institute of Human Virology, University of Maryland, Baltimore, agreed that the findings “support the critical nature of needle and syringe exchange programs.”
“As most cities in the United States fall well below the high coverage needle and syringe program threshold required to maximally prevent disease transmission, the study serves as a push toward an evidence-based harm reduction policy,” she said.
Dr. Kattakuzhy he added that the study “supports the need to longitudinally engage individuals after HCV treatment to monitor reinfection risk behaviors and test for reinfection,” she continued.
When it came to translating all the data to populations in the United States, she offered a more guarded view.
“Critically, the study population included only individuals who were engaged with OAT and adherent for 3 or more months, selecting to a population of individuals with high adherence and engagement in care,” Dr. Kattakuzhy said in an interview. “As such, the study findings are not applicable to other cross sections of the drug-using community, including individuals not engaged in OAT, and cohorts with higher rates of ongoing injection drug use. Furthermore, there are known genetic impacts on spontaneous clearance, and emerging data on the immunology of reinfection.
“Studies with a focus on less engaged, higher-risk, and minority populations with active drug use are required to answer the remaining questions in HCV reinfection,” she said.
The study was supported by Merck, the Australian Government Department of Health, and the Australian National Health and Medical Research Council. Dr. Grebely disclosed receiving funding from Cepheid, the manufacturer of the Xpert HCV assay. The other investigators disclosed additional relationships with Gilead, AbbVie, Cepheid, and others. Dr. Latkin and Dr. Kattakuzhy disclosed no relevant conflicts of interest.
The findings, which are based on prospective data from 13 countries, including the United States, and were published in Annals of Internal Medicine (2022 Aug 8. doi: 10.7326/M21-4119), should encourage physicians to treat HCV in people with a history of injection drug use, said lead author Jason Grebely, PhD.

“Critically, the study population included only individuals who were engaged with OAT and adherent for 3 or more months, selecting to a population of individuals with high adherence and engagement in care,” Dr. Kattakuzhy said in an interview. “As such, the study findings are not applicable to other cross sections of the drug-using community, including individuals not engaged in OAT, and cohorts with higher rates of ongoing injection drug use. Furthermore, there are known genetic impacts on spontaneous clearance, and emerging data on the immunology of reinfection.
“Studies with a focus on less engaged, higher-risk, and minority populations with active drug use are required to answer the remaining questions in HCV reinfection,” she said.
The study was supported by Merck, the Australian Government Department of Health, and the Australian National Health and Medical Research Council. Dr. Grebely disclosed receiving funding from Cepheid, the manufacturer of the Xpert HCV assay. The other investigators disclosed additional relationships with Gilead, AbbVie, Cepheid, and others. Dr. Latkin and Dr. Kattakuzhy disclosed no relevant conflicts of interest.
FROM ANNALS OF INTERNAL MEDICINE
Underweight in early childhood persists
The association was most pronounced for girls, as well as for children with lower growth rates, write the authors of the prospective Canadian cohort study published in JAMA Network Open.
The findings “highlight the importance of preventing underweight in early life,” because this can have “lasting effects” in later childhood, senior author Jonathon L. Maguire, MD, from St Michael’s Hospital Pediatric Clinic, and the University of Toronto said in an interview.
Methods and results
The study recruited 5,803 healthy children, mean age 4.07 months, between February 2008 and September 2020 during well-child visits at clinics in The Applied Research Group for Kids! (TARGet Kids!) practice-based research network in Canada. The study’s exclusion criteria included a premature birth, or a health condition affecting growth.
The primary outcome of the study was the child’s age- and sex-adjusted weight, also known as the body mass index z score (zBMI), between the ages of 2 and 10 years.
At baseline, a total of 550 children (9.5%) were classified as underweight, based on the World Health Organization definition of zBMI less than –2. Underweight children were more likely to be younger, have lower birth weight, and to report Asian maternal ethnicity, the researchers observed.
The study found that, compared with children with normal weight, those who were underweight in the first 2 years had lower zBMI at ages 5 and 10 years (–0.49 and –0.39 respectively). This meant that at 10 years old, they were a mean of 1.23 kg lighter than 10-year-olds who had been normal weight at age 2 years.
Height-for-age z score (HAZ) was also lower for underweight 2-year-olds (–0.24), making them a mean of 0.68 cm shorter than normal-weight 2-year-olds. This difference was attenuated at age 5 years.
Growth rate modified the association of underweight with both zBMI and HAZ. Among children who were underweight in the first 2 years, those with lower growth rate had lower zBMI at 10 years (–0.64) compared with those with average (–0.38) or high growth rate (0.11). Similarly, children who were underweight and had a lower growth rate at age 2 years also a lower HAZ at age 10 years (–0.12), compared with those with average (0.02) or high growth rates (0.16). These effects were more pronounced in girls.
Increased health risks linked with chronic underweight
This study did not assess the reasons for early underweight, Dr. Maguire commented in an interview. But, he cited challenges with dietary transitions as a possible explanation.
“Considerable dietary changes happen around 2 years of age with increasing diversity of foods as children transition from primarily liquid foods to primarily solid foods,” he noted.
Asked for comment on the study, Colleen Spees, PhD, associate professor in the division of medical dietetics and director of Hope lab at the Ohio State University, Columbus, said that “at age 10, it’s not surprising to see a lower zBMI and height-for-age in those that were underweight at age 2 with poor growth trajectories.”
Although, this is the first study she is aware of to document these findings in a Canadian cohort, “the results align with what we know about low birth weight and underweight infants and children in terms of linear growth trajectories from child stunting studies,” Dr. Spees said.
She said child stunting, which is more common in less developed countries where children have lower birth weights and greater socioeconomic and environmental risk factors, is defined by the WHO as impaired linear growth with adverse functional consequences.
“In short, a chronic underweight status in infants and young children can lead to greater risk of malnutrition, vitamin and mineral deficiencies, decreased immune function, as well as physical growth and development issues,” she said. “Hence, the most recent 2020-2025 Dietary Guidelines for Americans now includes both pregnancy, breastfeeding, and the first 2 years of life (referred to as the “first 1,000 days”) in their recommendations.”
She added that, if caregivers are concerned about their child’s weight, they should consult with their pediatrician to rule out any medical issues. If no medical issues are identified, they should ask for a referral to a pediatric dietitian.
The study was funded by the Canadian Institute of Health Research. Dr Maguire reported receiving grants from the CIHR, Physician Services, Ontario SPOR Support Unit, and Dairy Farmers of Canada during the conduct of the study and nonfinancial support from DDrops outside the submitted work. Other authors of the paper reported receiving grants from various institutions. Dr. Spees reported no relevant disclosures.

Is prostasin a clue to diabetes/cancer link?
People with elevated levels of protein prostasin seem to have a higher risk of developing diabetes and dying from cancer, according to a large, prospective, population-based study. The finding may provide new insights into why people with diabetes have an increased risk of cancer.
The study claims to be the first to investigate the link between plasma prostasin levels and cancer mortality, the study authors wrote in Diabetologia. The study analyzed plasma prostasin samples from 4,297 older adults (average age, 57.5 years) from the Malmö (Sweden) Diet and Cancer Study Cardiovascular Cohort.
“This study from the general population shows that prostasin, a protein that could be measured in blood, is associated with increased risk of developing diabetes,” senior author Gunnar Engström, MD, PhD, professor of epidemiology at Lund University in Malmö, Sweden, said in a comment. “Furthermore, it was associated with increased risk of death from cancer, especially in individuals with elevated glucose levels in the prediabetic range.
“The relationship between diabetes and cancer is poorly understood,” Dr. Engström said. “To our knowledge, this is the first big population study of prostasin and risk of diabetes.”
He noted previous studies have found a relationship between prostasin and cancer outcomes. “Prostasin could be a possible shared link between the two diseases and the results could help us understand why individuals with diabetes have increased risk of cancer.”
Patients in the study were assigned to quartiles based on prostasin levels. Those in the highest quartile had almost twice the risk of prevalent diabetes than did those in the lowest quartile (adjusted odds ratio, 1.95; 95% confidence interval, 1.39-2.76; P < .0001).
During the follow-up periods of 21.9 years for diabetes and 23.5 years for cancer, on average, 702 participants developed diabetes and 651 died from cancer. Again, the analysis found a significantly higher adjusted hazard ratio for participants in the fourth quartile: about 75% higher for diabetes (HR, 1.76; 95% CI, 1.41-2.19; P < .0001), and, after multivariable analysis, about 40% higher for death from cancer (HR, 1.43; 95% CI, 1.14-1.8; P = .0008).
Potential diabetes-cancer ‘interaction’
The study also identified what it called “a significant interaction” between prostasin and fasting blood glucose for cancer mortality risk (P = .022). In patients with impaired fasting blood glucose levels at baseline, the risk for cancer mortality was about 50% greater with each standard deviation increase in prostasin (HR, 1.52; 95% CI, 1.07-2.16; P = .019). Those with normal fasting blood glucose at baseline had a significantly lower risk with each SD increase in prostasin (HR, 1.11; 95% CI, 1.01-1.21; P = .025).
Further research is needed to validate the potential of prostasin as a biomarker for diabetes and cancer risks, Dr. Engström said. “The results need to be replicated in other studies. A study of cancer mortality in a big cohort of diabetes patients would be of great interest. We also need to examine whether prostasin is causally related to cancer and/or diabetes, or whether prostasin could act as a valuable risk marker in clinical settings. If causal, there could a possible molecular target for treatment.”
He added: “Biomarkers of diabetes and cancer are of great interest in the era of personalized medicine, both for disease prevention and for treatment of those with established disease.”
Li-Mei Chen, MD, PhD, a research associate professor at the University of Central Florida, Orlando, has studied the role of prostasin in epidemiology. She noted that one of the challenges of using prostasin in clinical or research settings is the lack of a standardized assay, which the Malmö study acknowledged. Dr. Engström and colleagues wrote that “prostasin levels were measured in arbitrary units (NPX values), and thus could not be compared directly with absolute values.”
Dr. Chen pointed out that the study reported a lower range of 0.24 pg/mL and an upper range of 7,800 pg/mL.
This means that, “in different groups that measure prostasin, the absolute quantity could have a difference in the thousands or tens of thousands,” she said. “That makes the judgment difficult of whether for this person you have a high level of prostasin in the blood and the other one you don’t if the difference is over a thousandfold.”
The Malmö study used the Proseek Multiplex Oncology I panel to determine plasma prostasin concentration, but Dr. Chen noted that she couldn’t find any data validating the panel for measuring prostasin. “It’s really hard for me to say whether this is of value or not because if the method that generated the data is not verified by another method, you don’t really know what you’re measuring.
“If the data are questionable, it’s really hard to say whether it means whether it’s a marker for cancer or diabetes,” Dr. Chen added. “That’s the biggest question I have, but actually the authors realize that.”
Dr. Engström confirmed that, “if prostasin is used to identify patients with increased risk of diabetes and cancer mortality, we also need to develop standardized assays for clinical use.”
Dr. Engström and coauthors had no disclosures. The study received funding from the Swedish Heart Lung Foundation, the National Natural Science Foundation of China, and the Natural Science Foundation of Jiangsu Province. The Malmö Diet and Cancer study received grants from the Swedish Cancer Society, the Swedish Medical Research Council, AFA Insurance, the Albert Påhlsson and Gunnar Nilsson Foundations, Malmö City Council, and Lund University.

Some GIs receive more industry money than others
Industry payments to U.S. gastroenterologists and hepatologists increased from 2014 to 2016 before beginning to steadily decrease after 2016, but they're largely concentrated among a small few, according to new research published in Gastroenterology.
The study aimed to identify trends in these specialties in the years after the Sunshine Act, enacted in 2010, and the federal program Open Payments, established in 2013.
“Although Open Payments launched in September of 2014, all the joinpoints in our study occurred more than a year later in 2016, suggesting a delay in observable changes in behavior on industry physician relationships,” wrote Xiaohan Ying, MD, of Weill Cornell Medicine in New York, and colleagues. “Since 2016, we have seen a sustained reduction in general industry payments to physicians while research payments remained stable, which is likely the desired outcome of this program.”
That’s also the conclusion of Lawrence Kosinski, MD, MBA, a spokesperson for the American Gastroenterological Association, who was not involved in the study.
“Most all of us are aware of the Sunshine Act and have reacted accordingly, so I am not surprised that reimbursement per physician has declined over the time period,” Dr. Kosinski told this news organization. “Many physicians are very sensitive to their reporting and have decreased their exposures,” said Dr. Kosinski, founder of SonarMD and a member of the Health & Human Services Advisory Committee on Value-Based Payment. “What does surprise me is the marked disparity in payments with a very small number of physicians receiving tremendous reimbursement from speaking engagements and promotions.”
The researchers retrospectively analyzed industry payments to 26,981 practicing pediatric and adults gastroenterologists and hepatologists using the National Plan and Provider Enumeration System and data from Open Payments between January 2014 and December 2020. The researchers excluded education payments and focused on general payments, which “include charitable contribution, speaker fees, consulting fees, ownership and investments, education, entertainment, food and beverages, gift, honoraria, royalty and license, and travel and lodging,” they reported.
Who gets paid, and how much?
While $27.5 million was going to research and grants, most of the payments ($403.3 million) were general payments; out of the total payments to specialists, $30 million went to hepatology, and $400.8 million went to gastroenterology. Nearly all of the general payments ($398.1 million) were for noneducation purposes; 90.5% of general payments went to men and 9.5% went to women, at an average of $17,167 per person. Nearly half the payments (43.8%) were for speaker fees, totaling $174.3 million, followed by 18.4% going to consulting ($73.1 million) and 12.9% going to food and beverages ($51.5 million).
Most of the physicians accepting payments (86.6%) received less than $10,000, but this made up only 8.3% of all payments. Meanwhile, 74% of all the payments, $294.6 million, went to just 3.1% of the physicians, all of whom received more than $100,000.
That breakdown is what most caught Dr. Kosinki’s attention.
“It’s one thing for a speaker to declare that they are receiving funds from pharma, but they never let us know how much,” Dr. Kosinski said. “Some of these speakers are realizing a very significant payment, which could change the opinions of those listening to their presentations.”
The authors reported that a group of 50 top earners (0.2%) received more than $1 million between 2014 and 2020. Their payments totaled $94.8 million and accounted for nearly a quarter (23.8%) of all the payments. All but one of these physicians were men, and one physician has received more than $1 million every year since 2014.
Payments for guideline authors explored
The authors examined payments to practicing U.S. gastroenterologists and hepatologists who helped write clinical guidelines for the following organizations:
- American Gastroenterological Association (AGA).
- American College of Gastroenterology (ACG).
- American Association for the Study of Liver Disease (AASLD).
- North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition (NASPGHAN).
- American Society for Gastrointestinal Endoscopy (ASGE).
The 186 guidelines published between 2014 and 2020 had 632 physician authors, 415 of whom were practicing gastroenterologists and hepatologists in the United States. Most of these physicians (85.8%) received at least one industry payment, with payments to guideline authors totaling $43.6 million.
Similar to the lopsided breakdown for total payments across all physicians, the majority of the payments (87.4%, or $38.1 million) went to one-quarter of the authors, who each received more than $100,000 per person. Meanwhile, 38.2% of the guideline authors received less than $10,000.
“However, these numbers are likely to decrease in the future as professional societies, such as AASLD, require a majority of the guideline authors to be free of conflict of interest relevant to the subject matter,” the authors wrote. They added that members selected as part of the AGA’s guideline development group (GDG) must report all conflicts of interest, including indirect and intellectual ones, and are recused or excluded when appropriate. These guideline development group participants must also forgo speaking and consulting arrangements until one year after the guideline’s publication.
Trends have been shifting
Total industry payments initially grew at a rate of 11.4% a year between 2014 and 2016 before decreasing at a rate of 5.8% per year after 2016 (P = .03). Though a similar trend occurred at the individual level, it did not reach significance.
However, the trend differed slightly between men and women: Payments to men increased 10.4% annually until 2016 then decreased 6.8% per year thereafter, but women’s payments increased 11.3% per year until 2019. Between 2014 and 2019, the amount per person payment dropped 3.5% annually to physicians overall, but payments to women initially increased 35.4% a year between 2014 and 2016 before decreasing.
Although not statistically significant, trends for types of payments showed that speaker and food/beverage fees have been declining since 2016 while consulting fees have been declining since 2014.
“The reduction in industry payments could be due to the Hawthorne effect, where physicians alter their behavior after becoming aware that their payments were being monitored,” the authors wrote. “Although many physicians see themselves as less vulnerable to be biased by industry compensation, studies have shown that even small payments can affect behavior such as prescription pattern. Additionally, studies have found that patients are less likely to trust physicians who have received industry payments.”
The authors acknowledged the role of industry payments in funding clinical trials but noted that pharmaceutical companies themselves have been taking on more design and execution of trials in recent decades. Further, only 6% of all payments went to research and grant funding, a little more than half the payments for food and beverages.
“While industry research funding is undeniably crucial, it simply plays a very small role in total industry compensation for physicians,” the authors wrote. “While speaker events could be beneficial and educational for physicians and other audiences, these events could also be utilized as means to promote specific products. While it is beneficial to seek input from experienced gastroenterologists for novel therapies and devices, actions should be taken to place limitations on industry payments to physicians, especially for the top earners.”
One author reported speaker fees from W.L. Gore & Associates and Cook Medical. The other two others had no disclosures. No external funding was noted. Dr. Kosinski reported having no relevant disclosures.

Industry payments to U.S. gastroenterologists and hepatologists increased from 2014 to 2016 before beginning to steadily decrease after 2016, but they're largely concentrated among a small few, according to new research published in Gastroenterology.
The study aimed to identify trends in these specialties in the years after the Sunshine Act, enacted in 2010, and the federal program Open Payments, established in 2013.
“Although Open Payments launched in September of 2014, all the joinpoints in our study occurred more than a year later in 2016, suggesting a delay in observable changes in behavior on industry physician relationships,” wrote Xiaohan Ying, MD, of Weill Cornell Medicine in New York, and colleagues. “Since 2016, we have seen a sustained reduction in general industry payments to physicians while research payments remained stable, which is likely the desired outcome of this program.”
That’s also the conclusion of Lawrence Kosinski, MD, MBA, a spokesperson for the American Gastroenterological Association, who was not involved in the study.
“Most all of us are aware of the Sunshine Act and have reacted accordingly, so I am not surprised that reimbursement per physician has declined over the time period,” Dr. Kosinski told this news organization. “Many physicians are very sensitive to their reporting and have decreased their exposures,” said Dr. Kosinski, founder of SonarMD and a member of the Health & Human Services Advisory Committee on Value-Based Payment. “What does surprise me is the marked disparity in payments with a very small number of physicians receiving tremendous reimbursement from speaking engagements and promotions.”
The researchers retrospectively analyzed industry payments to 26,981 practicing pediatric and adults gastroenterologists and hepatologists using the National Plan and Provider Enumeration System and data from Open Payments between January 2014 and December 2020. The researchers excluded education payments and focused on general payments, which “include charitable contribution, speaker fees, consulting fees, ownership and investments, education, entertainment, food and beverages, gift, honoraria, royalty and license, and travel and lodging,” they reported.

Neuropathy drives hypoglycemia cluelessness in T1D
Researchers published the study covered in this summary on researchsquare.com as a preprint that has not yet been peer reviewed.
Key takeaways
- In Japanese adults with type 1 diabetes insulin-pump treatment (continuous subcutaneous insulin infusion) and higher problem-solving perception appear protective against impaired awareness of hypoglycemia (IAH), while diabetic peripheral neuropathy (DPN) is associated with increased risk.
- Diabetes distress and fear of hypoglycemia are common in people with IAH.
Why this matters
- Adults with type 1 diabetes and IAH have a reduced ability to perceive hypoglycemic symptoms and are at risk of severe hypoglycemic events because they are unable to take immediate corrective action.
- This is the first study to identify protective factors and risk factors of IAH in Japanese adults with type 1 diabetes.
- People with IAH may plan to loosen tight glucose management and intentionally omit insulin injection to prevent severe hypoglycemia.
- The information in this report may help improve the management of people with problematic hypoglycemia, the authors suggested. Treatment with an insulin pump and structured education aimed at improving problem-solving skills may be useful interventions for adults with type 1 diabetes and IAH, they suggested.
Study design
- The study involved a cross-sectional analysis of 288 Japanese adults with type 1 diabetes who averaged 50 years old, had diabetes for an average of about 18 years, had an average hemoglobin A1c at baseline of 7.7%, and included about 37% men and 63% women.
- The cohort included 55 people with IAH (19%) and 233 with no impairment of their hypoglycemia awareness, based on their score on the .
Key results
- DPN was significantly more prevalent in the IAH group than in the control group (12.0% vs. 26.5%). A logistic regression analysis showed that the odds ratio for DPN was 2.63-fold higher among people with IAH, compared with those without IAH, but there were no differences in other complications or by HbA1c levels.
- Treatment with continuous subcutaneous insulin therapy (an insulin pump) was significantly less prevalent in the IAH group, compared with those without IAH (23.6% vs 39.5%), with an adjusted odds ratio of 0.48. The two subgroups showed no differences in use of continuous glucose monitoring, used by 56% of the people in each of the two subgroups.
- The two subgroups showed no differences in their healthy lifestyle score, sleep debt, or rates of excessive drinking.
- Mean autonomic symptom scores for both sweating and shaking were significantly reduced in the IAH group, but no between-group differences appeared for palpations or hunger.
- All mean neuroglycopenic symptom scores were significantly lower in those without IAH, including confusion and speech difficulty.
- Scores for measures of diabetes distress and for the worry component of the fear of hypoglycemia were significantly higher in the IAH group, but there were no differences in other psychological measures.
- Higher were significantly associated with decreased IAH risk with a calculated odds ratio of 0.54, but other aspects of hypoglycemia problem-solving such as detection control, goal setting, and strategy evaluation showed no significant links.
Limitations
- The study used a cross-sectional design, which is not suited to making causal inferences.
- The authors characterized DPN as either present or absent. They did not evaluate or analyze the severity of peripheral neuropathy.
- The authors evaluated diabetic cardiac autonomic neuropathy (DCAN) by a person’s coefficient of variation of R-R intervals, and definitive diagnosis of DCAN required at least two positive results on a cardiac autonomic test. More vigorous evaluation using a more definitive assessment of DCAN is needed to relate DCAN and IAH status.
Disclosures
- The study received no commercial funding.
- The authors have disclosed no relevant financial relationships.

‘Children are not little adults’ and need special protection during heat waves
After more than a week of record-breaking temperatures across much of the country, public health experts are cautioning that children are more susceptible to heat illness than adults are – even more so when they’re on the athletic field, living without air conditioning, or waiting in a parked car.
Cases of heat-related illness are rising with average air temperatures, and experts say almost half of those getting sick are children. The reason is twofold: Children’s bodies have more trouble regulating temperature than do those of adults, and they rely on adults to help protect them from overheating.
Parents, coaches, and other caretakers, who can experience the same heat very differently from the way children do, may struggle to identify a dangerous situation or catch the early symptoms of heat-related illness in children.
“Children are not little adults,” said Dr. Aaron Bernstein, a pediatric hospitalist at Boston Children’s Hospital.
Jan Null, a meteorologist in California, recalled being surprised at the effect of heat in a car. It was 86 degrees on a July afternoon more than 2 decades ago when an infant in San Jose was forgotten in a parked car and died of heatstroke.
Mr. Null said a reporter asked him after the death, “How hot could it have gotten in that car?”
Mr. Null’s research with two emergency doctors at Stanford University eventually produced a startling answer. Within an hour, the temperature in that car could have exceeded 120 degrees Fahrenheit. Their work revealed that a quick errand can be dangerous for a child left behind in the car – even for less than 15 minutes, even with the windows cracked, and even on a mild day.
As record heat becomes more frequent, posing serious risks even to healthy adults, the number of cases of heat-related illnesses has gone up, including among children. Those most at risk are young children in parked vehicles and adolescents returning to school and participating in sports during the hottest days of the year.
More than 9,000 high school athletes are treated for heat-related illnesses every year.
Heat-related illnesses occur when exposure to high temperatures and humidity, which can be intensified by physical exertion, overwhelms the body’s ability to cool itself. Cases range from mild, like benign heat rashes in infants, to more serious, when the body’s core temperature increases. That can lead to life-threatening instances of heatstroke, diagnosed once the body temperature rises above 104 degrees, potentially causing organ failure.
Prevention is key. Experts emphasize that drinking plenty of water, avoiding the outdoors during the hot midday and afternoon hours, and taking it slow when adjusting to exercise are the most effective ways to avoid getting sick.
Children’s bodies take longer to increase sweat production and otherwise acclimatize in a warm environment than adults’ do, research shows. Young children are more susceptible to dehydration because a larger percentage of their body weight is water.
Infants and younger children have more trouble regulating their body temperature, in part because they often don’t recognize when they should drink more water or remove clothing to cool down. A 1995 study showed that young children who spent 30 minutes in a 95-degree room saw their core temperatures rise significantly higher and faster than their mothers’ – even though they sweat more than adults do relative to their size.
Pediatricians advise caretakers to monitor how much water children consume and encourage them to drink before they ask for it. Thirst indicates the body is already dehydrated.
They should dress children in light-colored, lightweight clothes; limit outdoor time during the hottest hours; and look for ways to cool down, such as by visiting an air-conditioned place like a library, taking a cool bath, or going for a swim.
To address the risks to student athletes, the National Athletic Trainers’ Association recommends that high school athletes acclimatize by gradually building their activity over the course of 2 weeks when returning to their sport for a new season – including by slowly stepping up the amount of any protective equipment they wear.
“You’re gradually increasing that intensity over a week to 2 weeks so your body can get used to the heat,” said Kathy Dieringer, president of NATA.
Warning signs and solutions
Experts note a flushed face, fatigue, muscle cramps, headache, dizziness, vomiting, and a lot of sweating are among the symptoms of heat exhaustion, which can develop into heatstroke if untreated. A doctor should be notified if symptoms worsen, such as if the child seems disoriented or cannot drink.
Taking immediate steps to cool a child experiencing heat exhaustion or heatstroke is critical. The child should be taken to a shaded or cool area; be given cool fluids with salt, like sports drinks; and have any sweaty or heavy garments removed.
For adolescents, being submerged in an ice bath is the most effective way to cool the body, while younger children can be wrapped in cold, wet towels or misted with lukewarm water and placed in front of a fan.
Although children’s deaths in parked cars have been well documented, the tragic incidents continue to occur. According to federal statistics, 23 children died of vehicular heatstroke in 2021. Mr. Null, who collects his own data, said 13 children have died so far this year.
Caretakers should never leave children alone in a parked car, Mr. Null said. Take steps to prevent young children from entering the car themselves and becoming trapped, including locking the car while it’s parked at home.
More than half of cases of vehicular pediatric heatstroke occur because a caretaker accidentally left a child behind, he said. While in-car technology reminding adults to check their back seats has become more common, only a fraction of vehicles have it, requiring parents to come up with their own methods, like leaving a stuffed animal in the front seat.
The good news, Mr. Null said, is that simple behavioral changes can protect youngsters. “This is preventable in 100% of the cases,” he said.
A lopsided risk
People living in low-income areas fare worse when temperatures climb. Access to air conditioning, which includes the ability to afford the electricity bill, is a serious health concern.
A study of heat in urban areas released last year showed that low-income neighborhoods and communities of color experience much higher temperatures than those of wealthier, White residents. In more impoverished areas during the summer, temperatures can be as much as 7 degrees Fahrenheit warmer.
The study’s authors said their findings in the United States reflect that “the legacy of redlining looms large,” referring to a federal housing policy that refused to insure mortgages in or near predominantly Black neighborhoods.
“These areas have less tree canopy, more streets, and higher building densities, meaning that in addition to their other racist outcomes, redlining policies directly codified into law existing disparity in urban land use and reinforced urban design choices that magnify urban heating into the present,” they concluded.
Dr. Bernstein, who leads Harvard’s Center for Climate, Health, and the Global Environment, coauthored a commentary in JAMA arguing that advancing health equity is critical to action on climate change.
The center works with front-line health clinics to help their predominantly low-income patients respond to the health impacts of climate change. Federally backed clinics alone provide care to about 30 million Americans, including many children, he said.
Dr. Bernstein also recently led a nationwide study that found that from May through September, days with higher temperatures are associated with more visits to children’s hospital emergency rooms. Many visits were more directly linked to heat, although the study also pointed to how high temperatures can exacerbate existing health conditions such as neurological disorders.
“Children are more vulnerable to climate change through how these climate shocks reshape the world in which they grow up,” Dr. Bernstein said.
Helping people better understand the health risks of extreme heat and how to protect themselves and their families are among the public health system’s major challenges, experts said.
The National Weather Service’s heat alert system is mainly based on the heat index, a measure of how hot it feels when relative humidity is factored in with air temperature.
But the alerts are not related to effects on health, said Kathy Baughman McLeod, director of the Adrienne Arsht-Rockefeller Foundation Resilience Center. By the time temperatures rise to the level that a weather alert is issued, many vulnerable people – like children, pregnant women, and the elderly – may already be experiencing heat exhaustion or heatstroke.
The center developed a new heat alert system, which is being tested in Seville, Spain, historically one of the hottest cities in Europe.
The system marries metrics such as air temperature and humidity with public health data to categorize heat waves and, when they are serious enough, give them names – making it easier for people to understand heat as an environmental threat that requires prevention measures.
The categories are determined through a metric known as excess deaths, which compares how many people died on a day with the forecast temperature versus an average day. That may help health officials understand how severe a heat wave is expected to be and make informed recommendations to the public based on risk factors such as age or medical history.
The health-based alert system would also allow officials to target caretakers of children and seniors through school systems, preschools, and senior centers, Ms. Baughman McLeod said.
Giving people better ways to conceptualize heat is critical, she said.
“It’s not dramatic. It doesn’t rip the roof off of your house,” Ms. Baughman McLeod said. “It’s silent and invisible.”

Registry launched to reach more patients with PF
The Pulmonary Fibrosis Foundation (PFF) has launched a new initiative in which they hope to capture a far more diverse representation of patients with pulmonary fibrosis (PF) than the current registry allows them to do, a press release from the PFF indicated.
“The existing registry we have – the PFF Patient Registry – is limited to our care centers, which are primarily academic clinical institutions and we have only a few thousand patients within that registry,” Junelle Speller, MBA, vice president of the PFF Registry, told this news organization.
“We wanted to go beyond these care centers and capture patients in community centers, and in rural settings to provide a more complete understanding of patients with this disease and, of course, have a larger sample size,” she added.
“ across all parts of the United States and, most importantly, accelerate the research on PF toward improving earlier diagnosis, treatment, and outcomes for these patients,” Ms. Speller said.
Passive versus active
The PFF Community Registry differs in its structure and purpose from the PFF Patient Registry, as Ms. Speller explained. First, the PFF Patient Registry, established in 2016, is “passive” in its nature in that whatever information is entered into a patient’s electronic medical record or clinical chart on a routine office visit is abstracted and captured in the registry. By contrast, the PFF Community Registry is asking for self-reported data from patients, “so it’s more of an ‘active’ registry and will give us a chance to have a bidirectional connection with participants, provide email updates and newsletters, and give patients an opportunity to participate in future studies within the registry as well as in clinical trials,” she noted.
The two registries still overlap in that both capture demographic data on patients’ medical and family histories as well as any medications patients may be taking, but the Community Registry will also capture information with respect to education, employment, patient-reported outcomes, and quality of life metrics. “It will also let us know how patients feel about continued education on the disease itself and patient participation in support groups,” Ms. Speller observed.
The Community Registry will also collect information from lung transplant recipients who have had PF or any other form of interstitial lung disease (ILD) as well as information from caregivers and family members affected by the patient’s disease. As Ms. Speller noted, both PF and other forms of ILD (of which there are more than 200 types) are all characterized by inflammation or scarring in the lung. “Patients are often misdiagnosed, and it can take months, even years, to identify the disease,” Ms. Speller said.
From there, it can be a very long and difficult road ahead, with no cure in sight, although several antifibrotic drugs do help slow disease progression. Typically, onset is around the age of 60 and symptoms include chronic dry cough, fatigue, shortness of breath, weakness, discomfort in the chest, and sometimes unexplained weight loss. Some patients do have a history of smoking, but not all, Ms. Speller noted. So far, registry data suggest PF largely occurs in White patients.
“We’re very excited about the Community Registry, particularly about reaching into communities that we haven’t been able to reach with our existing registry,” Ms. Speller noted. “The rural population in particular is often underserved, so we are really looking forward to capturing data from these patients as well as those from community centers within smaller and larger cities,” she observed.
“A powerful aspect of the Community Registry is that we can use the information gained from it to understand the experience of individuals living with PF, and how it impacts their lives and those of their families and caregivers,” Kevin Flaherty, MD, steering committee chair, PFF Registry, said in a statement.
“Researchers can also look at the data to better understand fibrotic lung diseases and learn about effective approaches to improve patient care,” he added.
Patients who wish to join the PFF Community Registry can sign up at pffregistry.org. To learn more about PF and its risk factors, readers are invited to visit www.AboutPF.org. More than 250,000 patients in the United States are living with either PF or other types of ILD.
Ms. Speller and Dr. Flaherty disclosed no financial conflicts of interest. The PFF Registry is supported by its founding partner, Genentech, Visionary Partner, United Therapeutics, and its sustaining partner, Boehringer Ingelheim, as well as many donors.

Patients who wish to join the PFF Community Registry can sign up at pffregistry.org. To learn more about PF and its risk factors, readers are invited to visit www.AboutPF.org. More than 250,000 patients in the United States are living with either PF or other types of ILD.
Ms. Speller and Dr. Flaherty disclosed no financial conflicts of interest. The PFF Registry is supported by its founding partner, Genentech, Visionary Partner, United Therapeutics, and its sustaining partner, Boehringer Ingelheim, as well as many donors.

The Pulmonary Fibrosis Foundation (PFF) has launched a new initiative in which they hope to capture a far more diverse representation of patients with pulmonary fibrosis (PF) than the current registry allows them to do, a press release from the PFF indicated.
“The existing registry we have – the PFF Patient Registry – is limited to our care centers, which are primarily academic clinical institutions and we have only a few thousand patients within that registry,” Junelle Speller, MBA, vice president of the PFF Registry, told this news organization.
“We wanted to go beyond these care centers and capture patients in community centers, and in rural settings to provide a more complete understanding of patients with this disease and, of course, have a larger sample size,” she added.
“ across all parts of the United States and, most importantly, accelerate the research on PF toward improving earlier diagnosis, treatment, and outcomes for these patients,” Ms. Speller said.
Passive versus active
The PFF Community Registry differs in its structure and purpose from the PFF Patient Registry, as Ms. Speller explained. First, the PFF Patient Registry, established in 2016, is “passive” in its nature in that whatever information is entered into a patient’s electronic medical record or clinical chart on a routine office visit is abstracted and captured in the registry. By contrast, the PFF Community Registry is asking for self-reported data from patients, “so it’s more of an ‘active’ registry and will give us a chance to have a bidirectional connection with participants, provide email updates and newsletters, and give patients an opportunity to participate in future studies within the registry as well as in clinical trials,” she noted.
The two registries still overlap in that both capture demographic data on patients’ medical and family histories as well as any medications patients may be taking, but the Community Registry will also capture information with respect to education, employment, patient-reported outcomes, and quality of life metrics. “It will also let us know how patients feel about continued education on the disease itself and patient participation in support groups,” Ms. Speller observed.
The Community Registry will also collect information from lung transplant recipients who have had PF or any other form of interstitial lung disease (ILD) as well as information from caregivers and family members affected by the patient’s disease. As Ms. Speller noted, both PF and other forms of ILD (of which there are more than 200 types) are all characterized by inflammation or scarring in the lung. “Patients are often misdiagnosed, and it can take months, even years, to identify the disease,” Ms. Speller said.
From there, it can be a very long and difficult road ahead, with no cure in sight, although several antifibrotic drugs do help slow disease progression. Typically, onset is around the age of 60 and symptoms include chronic dry cough, fatigue, shortness of breath, weakness, discomfort in the chest, and sometimes unexplained weight loss. Some patients do have a history of smoking, but not all, Ms. Speller noted. So far, registry data suggest PF largely occurs in White patients.
“We’re very excited about the Community Registry, particularly about reaching into communities that we haven’t been able to reach with our existing registry,” Ms. Speller noted. “The rural population in particular is often underserved, so we are really looking forward to capturing data from these patients as well as those from community centers within smaller and larger cities,” she observed.

Topline results for novel drug in ATTR amyloidosis with cardiomyopathy
The RNA interference (RNAi) therapeutic patisiran (Onpattro, Alnylam Pharmaceuticals) led to statistically significant improvement in functional capacity and quality of life in adults with transthyretin-mediated (ATTR) amyloidosis with cardiomyopathy in the phase 3 APOLLO-B study, according to topline results released Aug. 3.
“We are thrilled that APOLLO-B successfully met all its major objectives, which we believe for the first time validates the hypothesis that TTR silencing by an RNAi therapeutic can be an effective approach for treating the cardiomyopathy of ATTR amyloidosis,” Pushkal Garg, MD, Alnylam chief medical officer, said in a news release.
The Food and Drug Administration approved patisiran in 2018 for polyneuropathy caused by hereditary ATTR in adults on the basis of results of the APOLLO phase 3 trial, as reported by this news organization.
APOLLO-B enrolled 360 adults with ATTR amyloidosis (hereditary or wild-type) with cardiomyopathy at 69 centers in 21 countries. Half were randomly allocated to 0.3 mg/kg of patisiran or placebo administered intravenously every 3 weeks for 12 months.
The study met the primary endpoint of a statistically significant improvement from baseline in the 6-minute walk test at 12 months compared with placebo (P = .0162), the company said.
The study also met the first secondary endpoint of a statistically significant improvement from baseline in quality of life compared with placebo, as measured by the Kansas City Cardiomyopathy Questionnaire (P = .0397).
The patisiran and placebo groups had similar frequencies of adverse events (91% and 94%, respectively) and serious adverse events (34% and 35%, respectively).
“ATTR amyloidosis with cardiomyopathy is an increasingly recognized cause of heart failure, affecting greater than 250,000 patients around the world. These patients have limited treatment options, and disease progression is common. As such, we are encouraged to see the potential of patisiran to improve the functional capacity and quality of life of patients living with this fatal, multisystem disease,” Dr. Garg said in the release.
Full results from APOLLO-B will be presented at a late-breaker session at the 18th International Symposium on Amyloidosis in September in Heidelberg, Germany.
Based on these results, the company plans to file a supplementary new drug application (sNDA) for patisiran for this indication with the FDA later this year, the release noted.
