The SGLT2 inhibitor dapagliflozin scored a clear win in a randomized, controlled trial with more than 300 U.S. patients with heart failure with preserved ejection fraction (HFpEF), showing a significant and clinically meaningful benefit for the primary endpoint, a KCCQ measure of symptoms and physical limitations, after 12 weeks of treatment.

These results in the PRESERVED-HF study follow closely on the heals of the initial report from the EMPEROR-Preserved trial that showed a benefit from a different sodium-glucose cotransporter 2 (SGLT2) inhibitor, empagliflozin (Jardiance) in nearly 6,000 randomized patients for the primary endpoint of preventing cardiovascular death or hospitalizations for heart failure.

In PRESERVED-HF, patients with HFpEF who received a standard, once-daily dose of dapagliflozin (Farxiga) had an average 5.8-point improvement in their condition as measured by the Kansas City Cardiomyopathy Questionnaire clinical summary score (KCCQ-CS), the study’s primary endpoint.

This is “the first study to demonstrate that an SGLT2 inhibitor dapagliflozin significantly improves symptoms, physical limitations, and 6-minute walking distance in patients with HFpEF,” Mikhail N. Kosiborod, MD, reported at the annual scientific meeting of the Heart Failure Society of America. The secondary endpoint of 6-minute walking distance “has been very difficult to improve in many previous studies of other treatments” tested in patients with HFpEF, noted Dr. Kosiborod, a cardiologist and codirector of the Cardiometabolic Center of Excellence at Saint Luke’s Mid-America Heart Institute.

The results are “highly complementary” to the findings from large outcome trials, such as the findings from EMPEROR-Preserved, he said, and collectively the recent findings from these studies of SGLT2 inhibitors in patients with HFpEF identify drugs in this class as a “new treatment option” for patients with a disorder that until now had no treatment with unequivocally proven efficacy and safety.
 

‘Impressive and unprecedented’ findings

The findings are “really impressive and unprecedented,” said Milton Packer, MD, a cardiologist at Baylor University Medical Center in Dallas who was not involved in the study. “This is the largest KCCQ benefit ever seen in either patients with HFpEF or in patients with heart failure with reduced ejection fraction,” said Dr. Packer, one of the investigators who led the EMPEROR-Preserved trial.

PRESERVED-HF randomized 324 patients diagnosed with heart failure and with a left ventricular ejection fraction of 45% or higher at any of 26 U.S. centers, with 304 patients completing the planned final analysis after 12 weeks on treatment. Patients could be in New York Heart Association (NYHA) functional class II-IV, they had to have a baseline N-terminal pro-brain natriuretic peptide (NT-proBNP) level of at least 225 pg/mL (or higher if they also had atrial fibrillation), and they required at least one of three markers of established heart failure: recent hospitalization for heart failure or an urgent outpatient visit that required treatment with an IV diuretic, elevated filling pressure measured by left or right catheterization, or structural heart disease detected by echocardiography.

The average age of the enrolled patients was 70 years, and they had been diagnosed with heart failure for about 3 years; 57% were women, 30% were African American, and their median body mass index was 35 kg/m². Roughly 42% had NYHA class III or IV disease, 56% had type 2 diabetes, their median estimated glomerular filtration rate was about 55 mL/min per 1.73m², their median KCCQ-CS score at baseline was about 62, and their average 6-minute walk distance was 244 m.

These and other features of the enrolled population define a distinctly U.S. patient population, stressed Dr. Kosiborod, professor of medicine at the University of Missouri–Kansas City.

“The patients we enrolled are the patients we see in U.S. clinical practice,” he said in an interview. Importantly, the patient profile of a median BMI of 35 kg/m², a median KCCQ-CS score of 62 – “quite low,” noted Dr. Kosiborod – and having more than 40% of patients in NYHA functional class III defines a study population with a substantially greater burden of obesity, symptoms, and functional impairment compared with those enrolled in prior trials involving patients with HFpEF such as EMPEROR-Preserved.
 

Results complement findings from larger trials

PRESERVED-HF was an investigator-initiated study designed to inform clinical practice, not as a pivotal trial like EMPEROR-Preserved, which aims to gather evidence to support a new indication for regulatory approval. (On Sept. 9, 2021, the Food and Drug Administration granted empagliflozin “breakthrough therapy” status for treating HFpEF based on the EMPEROR-Preserved results, which will fast-track the agency’s decision on this indication.)

Dr. Kosiborod noted that he and his associates designed PRESERVED-HF with adequate patient numbers to power a statistically valid assessment of effect on KCCQ-CS score. While the new findings will not by themselves lead to a new indication for dapagliflozin to treat patients with HFpEF, they will potentially complement the pending results of another trial, DELIVER, by showing efficacy and safety in a uniquely U.S. patient population. DELIVER is a pivotal, global trial of dapagliflozin in more than 6,000 patients with HFpEF that’s on track to report findings in 2022.

Dr. Kosiborod also stressed that dapagliflozin has U.S.-approved indications for treating patients with type 2 diabetes, and for patients with chronic kidney disease, and that a majority of patients enrolled in PRESERVED-HF had one or both of these conditions. That makes the new findings especially compelling for patients with either type 2 diabetes or chronic kidney disease and HFpEF who are not already receiving an SGLT2 inhibitor.

Other findings that he reported showed a range of benefits consistent with the primary endpoint, including the KCCQ overall summary score, which also showed a significant 4.5-point average increase over placebo after 12 weeks. Analysis by the percentage of patients achieving at least a 5-point improvement in the KCCQ clinical summary score (the threshold for a clinically meaningful improvement) showed that about 45% of patients treated with dapagliflozin reached this mark compared with roughly 35% of patients in the placebo arm, indicating a number needed to treat of nine to have one additional patient achieve this threshold after 12 weeks. Average improvement in 6-minute walk distance was about 20 m with dapagliflozin compared with placebo.

No heterogeneity of effect by baseline ejection fraction.

Subgroup analyses showed no heterogeneity of response across 12 different ways of subdividing the study population, including age, sex, race, diabetes status, and BMI. The median left ventricular ejection fraction among enrolled patients was 60%, and the findings showed identical KCCQ improvements among patients with ejection fractions less than the median and those with an ejection fraction above the median.

This last finding was especially relevant because the EMPEROR-Preserved results showed a possible signal of heterogeneity by ejection fraction and an attenuated effect among patients with HFpEF and an ejection fraction above the 60%-65% range, although the certainty of this finding is currently controversial.

The impact of empagliflozin on KCCQ clinical summary score in EMPEROR-Preserved showed an average incremental improvement of 1.32 points compared with placebo, a significant difference, but more modest than the increment from dapagliflozin treatment seen in PRESERVED-HF. Dr. Kosiborod hypothesized that this difference might be mostly because of the different patient populations enrolled in the two studies.

Dr. Kosiborod noted that a report on the PRESERVED-HF results will soon appear in Nature Medicine.

PRESERVED-HF was funded by AstraZeneca, which markets dapagliflozin (Farxiga), but the trials’ design and conduct were independent of this funding source. Dr. Kosiborod has been a consultant to AstraZeneca and numerous other companies, and he has received research funding from AstraZeneca and Boehringer Ingelheim. Dr. Packer has had financial relationships with AstraZeneca and numerous other companies.

The 30-day mortality rate was significantly lower among hospitalized patients treated by full-time clinicians, compared with those treated by part-time clinicians, in a new study.

The number of physicians working part time in the United States has increased by nearly 11% since 1993, and as more physicians opt for part-time work, quality of care deserves further study, the investigators wrote in JAMA Internal Medicine. Most studies comparing outcomes for patients treated by full-timers and part-timers have focused on outpatient care settings, where mortality is low and the potential for confounding is high, according to the study authors Hirotaka Kato, PhD, of Keio University in Tokyo, and colleagues. The new study, in contrast, is based on data from nearly 400,000 hospitalizations.

The researchers conducted a cross-sectional analysis on a 20% random sample of Medicare patients aged 65 years and older who were treated by a hospitalist for an emergency medical condition between 2011 and 2016. They examined associations between the number of days per year worked by hospitalists and they 30-day mortality rates among the patients they treated. The researchers analyzed a total of 392,797 hospitalizations in which patients were treated by 19,170 hospitalists. The mean age of the hospitalists was 41 years; 39% were female. Clinician work days were divided into quartiles.

Overall, the 30-day mortality was significantly higher among patients treated by clinicians in the bottom quartile with the fewest number of days worked, compared with those treated by clinicians in the top quartile with the most days worked (10.5% vs. 9.6%). The rates were similar in the second and third quartiles (10.0% and 9.5%).

The average number of days worked clinically per year was 57.6 in the lowest quartile versus 163.3 in the highest quartile, a 65% difference. No significant associations were noted between days worked and patient outcomes with regard to physician age, gender, or hospital teaching status.

Hospital 30-day readmission rates were examined as a secondary outcome, but there was no association between patient readmission and the number of days worked by the clinician. The adjusted 30-day readmission rate for clinicians in the bottom quartile of days worked, compared with those in the top quartile, was 15.3% versus 15.2% (P = .61).

The researchers found no difference in patients’ severity of illness (defined by expected mortality) or reason for admission between physicians in the different quartiles of days worked. They eliminated confounding from hospital-level differences by comparing outcomes of patients between physicians in the same hospital.
 

Possible explanations for worse patient outcomes

“As the number of physicians who engage in part-time clinical work continues to increase, these findings should lead to careful consideration by health systems to reevaluate preventive measures to address potential unintended patient harm,” the researchers wrote.

The researchers proposed several reasons for the association between fewer clinical work days and worse patient outcomes. First, physicians putting in less clinical time may be less updated on the latest guidelines, their skills may decline with less frequent patient care, and they may be less familiar with the nurses, medical assistants, and support staff, which may contribute to poor teamwork. The researchers also stated that some part-time physicians may need to balance nonclinical responsibilities, such as research or administrative tasks, concurrently with inpatient care. “It is also possible that physicians with less clinical knowledge or skills select to become part-time physicians, whereas physicians with higher clinical performance decide to work full time,” they noted.

The study findings were limited by several factors including the observational design and potential for unmeasured confounding variables, and the results may not generalize to younger patients or surgical patients, the researchers noted. Also, the study did not include care by hospitalists that was not billed, days in which clinicians treated non-Medicare patients or patients not part of the Medicare sample, or information about the reasons for clinicians’ part-time work.

However, the results were strengthened by the large sample size, and suggest the need for better institutional support to maintain the clinical performance of physicians who may be balancing a range of obligations, they concluded.

Clinician work issues have renewed relevance

“The data in this paper are from 2016 and earlier, but it is possibly event more relevant today than then,” Eileen Barrett, MD, of the University of New Mexico, Albuquerque, said in an interview. “The pandemic has exacerbated stressors being experienced by physicians and other health care workers, including higher clinical workloads and burnout, and spotlighted gendered effects on women in the workforce, which is likely to drive more physicians to part-time work.

“Reporting these findings now is so important so they can contribute to a shared mental model of the challenges physicians and hospitals face as we seek solutions to deliver high-quality and high-value care with an engaged, professionally fulfilled workforce,” she emphasized.

Dr. Barrett said she was surprised that the study did not show differences in readmission rates depending on the number of shifts worked, and also that the results were not different when considering expected mortality.

“However unpopular it may be to say so, physicians and administrators should assume these results apply to their practice unless they have examined their own data and know it does not,” Dr. Barrett said. “With that in mind, hospitals, administrators, and regulatory bodies have an urgent need to examine and reduce the forces driving physicians to part-time clinical work. Some of these factors include the absence of childcare, excessive paperwork, burnout, administrative duties, and valued experiences such as teaching, leadership, and research that keep clinicians from the bedside.

“Additionally, steps should be taken to reduce the administrative complexity that makes providing the best care to patients difficult and requires hospitalists to create ‘workarounds,’ because those who work fewer clinical hours may not know how to do these, nor how to advocate for their patients,” Dr. Barrett emphasized.

“Additional research is needed to determine how mortality varies by number of clinical shifts for pediatric and obstetric patients who are infrequently covered by Medicare, also how the pandemic and increasing administrative complexity since the time the data was obtained affect patient care,” Dr. Barrett noted.

The study was supported by a grant from the Japan Society for the Promotion of Science to lead author Dr. Kato, who had no financial conflicts to disclose. Dr. Barrett, who serves on the editorial advisory board of Internal Medicine News, had no financial conflicts.

“The data in this paper are from 2016 and earlier, but it is possibly event more relevant today than then,” Eileen Barrett, MD, of the University of New Mexico, Albuquerque, said in an interview. “The pandemic has exacerbated stressors being experienced by physicians and other health care workers, including higher clinical workloads and burnout, and spotlighted gendered effects on women in the workforce, which is likely to drive more physicians to part-time work.

“Reporting these findings now is so important so they can contribute to a shared mental model of the challenges physicians and hospitals face as we seek solutions to deliver high-quality and high-value care with an engaged, professionally fulfilled workforce,” she emphasized.

Dr. Barrett said she was surprised that the study did not show differences in readmission rates depending on the number of shifts worked, and also that the results were not different when considering expected mortality.

“However unpopular it may be to say so, physicians and administrators should assume these results apply to their practice unless they have examined their own data and know it does not,” Dr. Barrett said. “With that in mind, hospitals, administrators, and regulatory bodies have an urgent need to examine and reduce the forces driving physicians to part-time clinical work. Some of these factors include the absence of childcare, excessive paperwork, burnout, administrative duties, and valued experiences such as teaching, leadership, and research that keep clinicians from the bedside.

“Additionally, steps should be taken to reduce the administrative complexity that makes providing the best care to patients difficult and requires hospitalists to create ‘workarounds,’ because those who work fewer clinical hours may not know how to do these, nor how to advocate for their patients,” Dr. Barrett emphasized.

“Additional research is needed to determine how mortality varies by number of clinical shifts for pediatric and obstetric patients who are infrequently covered by Medicare, also how the pandemic and increasing administrative complexity since the time the data was obtained affect patient care,” Dr. Barrett noted.

The study was supported by a grant from the Japan Society for the Promotion of Science to lead author Dr. Kato, who had no financial conflicts to disclose. Dr. Barrett, who serves on the editorial advisory board of Internal Medicine News, had no financial conflicts.

The 30-day mortality rate was significantly lower among hospitalized patients treated by full-time clinicians, compared with those treated by part-time clinicians, in a new study.

The number of physicians working part time in the United States has increased by nearly 11% since 1993, and as more physicians opt for part-time work, quality of care deserves further study, the investigators wrote in JAMA Internal Medicine. Most studies comparing outcomes for patients treated by full-timers and part-timers have focused on outpatient care settings, where mortality is low and the potential for confounding is high, according to the study authors Hirotaka Kato, PhD, of Keio University in Tokyo, and colleagues. The new study, in contrast, is based on data from nearly 400,000 hospitalizations.

The researchers conducted a cross-sectional analysis on a 20% random sample of Medicare patients aged 65 years and older who were treated by a hospitalist for an emergency medical condition between 2011 and 2016. They examined associations between the number of days per year worked by hospitalists and they 30-day mortality rates among the patients they treated. The researchers analyzed a total of 392,797 hospitalizations in which patients were treated by 19,170 hospitalists. The mean age of the hospitalists was 41 years; 39% were female. Clinician work days were divided into quartiles.

Overall, the 30-day mortality was significantly higher among patients treated by clinicians in the bottom quartile with the fewest number of days worked, compared with those treated by clinicians in the top quartile with the most days worked (10.5% vs. 9.6%). The rates were similar in the second and third quartiles (10.0% and 9.5%).

The average number of days worked clinically per year was 57.6 in the lowest quartile versus 163.3 in the highest quartile, a 65% difference. No significant associations were noted between days worked and patient outcomes with regard to physician age, gender, or hospital teaching status.

Hospital 30-day readmission rates were examined as a secondary outcome, but there was no association between patient readmission and the number of days worked by the clinician. The adjusted 30-day readmission rate for clinicians in the bottom quartile of days worked, compared with those in the top quartile, was 15.3% versus 15.2% (P = .61).

The researchers found no difference in patients’ severity of illness (defined by expected mortality) or reason for admission between physicians in the different quartiles of days worked. They eliminated confounding from hospital-level differences by comparing outcomes of patients between physicians in the same hospital.
 

Possible explanations for worse patient outcomes

“As the number of physicians who engage in part-time clinical work continues to increase, these findings should lead to careful consideration by health systems to reevaluate preventive measures to address potential unintended patient harm,” the researchers wrote.

The researchers proposed several reasons for the association between fewer clinical work days and worse patient outcomes. First, physicians putting in less clinical time may be less updated on the latest guidelines, their skills may decline with less frequent patient care, and they may be less familiar with the nurses, medical assistants, and support staff, which may contribute to poor teamwork. The researchers also stated that some part-time physicians may need to balance nonclinical responsibilities, such as research or administrative tasks, concurrently with inpatient care. “It is also possible that physicians with less clinical knowledge or skills select to become part-time physicians, whereas physicians with higher clinical performance decide to work full time,” they noted.

The study findings were limited by several factors including the observational design and potential for unmeasured confounding variables, and the results may not generalize to younger patients or surgical patients, the researchers noted. Also, the study did not include care by hospitalists that was not billed, days in which clinicians treated non-Medicare patients or patients not part of the Medicare sample, or information about the reasons for clinicians’ part-time work.

However, the results were strengthened by the large sample size, and suggest the need for better institutional support to maintain the clinical performance of physicians who may be balancing a range of obligations, they concluded.

Obese or overweight children with asthma could be using inhaled corticosteroids (ICS) to no avail, combined results from observational studies suggest.

Using Mendelian randomization, a method for reducing bias in observational studies, investigators from the University of Amsterdam Medical Center performed an analysis of data from four cross-sectional studies and one cohort study on a total of 1,511 children with asthma.

They showed that every 1-unit increase in the body mass index (BMI) z score was associated with a more than twofold higher odds ratio for exacerbation, reported Cristina Longo, PhD, a former postdoctoral fellow at AMC, and assistant professor of medicine at the University of Montreal.

“In this large, multicenter Mendelian randomization study, our findings support current evidence that children with higher BMI status respond inadequately to inhaled corticosteroids, and that this association is likely not explained by measured confounding or reverse causation,” she said in an oral abstract presentation during the European Respiratory Society International Congress.
 

Unmeasured confounding

The obese-asthma phenotype in children is characterized by reduced lung function, high symptom expression, poor response to ICS, and high health care utilization.

“While most observational studies suggest that weight status is associated with asthma exacerbations, despite using inhaled corticosteroids, it’s unclear whether these associations may be due to unmeasured confounding or reverse causation, which captures the idea that perhaps obesity is a consequence rather than a cause of uncontrolled severe asthma,” she said.

Traditional observational studies of the obesity-asthma link rely on comparing data on asthma in a target population and comparing nonobese patients with obese patients. The problem with this method, Dr. Longo contended, is that the exposure assignment – weight status – is not random, and could lead to bias from potential imbalance of confounders, leading to unintentionally biased results.

In contrast, Mendelian randomization uses genetic data to approximate random assignment of exposures, using a risk score for BMI based on genetic susceptibility. The score is based on the accumulation of genetic variants (single-nucleotide polymorphisms, or SNPs) that predispose individuals to obesity, with higher numbers of variants results in a higher risk score.

The scores are then used to determine the comparison groups for evaluating the obesity-asthma association.
 

Alphabet soup

Dr. Longo and colleagues analyzed data on a total 1,511 children enrolled in four observational studies (PACMAN, PAGES, HPR, CLARA) and one cohort study (ALSPAC).

They included children with an asthma diagnosis who used ICS and had available information on both BMI and genetics.

The Mendelian randomization analysis was based on a weighted allele score based on 97 SNPs predictive of BMI based on large-scale genomewide association studies. The exposure for the analysis was age- and sex-adjusted BMI z scores based on World Health Organization growth charts for children.

They found that using the Mendelian randomization approach, for each standard deviation increase in BMI, the OR for any parent-reported asthma exacerbations, including urgent care visits or use of oral corticosteroids, was 2.31 (95% confidence interval, 1.26-4.25).

In contrast, if the traditional observational model had been used, the OR would be a nonsignificant 1.10 (95% CI, 0.99-1.22).

“Treatment guidelines recommend steroids for children with asthma who have a higher-than-normal BMI,” Dr. Longo said in a statement. “Our research group felt that the one-size fits-all approach to treating children with asthma with inhaled steroids as their first-line treatment, particularly those with excess weight, warrants revision. At the very least, research identifying potential alternative treatments should be encouraged and prioritized, especially since 30% of children with asthma are also obese. With the childhood obesity epidemic rising, we expect this percentage to increase meaning this problem of poor control will be seen more frequently in routine clinical practice.”

Christopher E. Brightling, PhD, professor of respiratory medicine at the University of Leicester (England), commented that “this is very good and fascinating research with findings that are important and novel.

“It sheds light on the complex interplay between genes, weight, and response to inhaled corticosteroids, underscoring the need to combine drug treatments with lifestyle and diet modifications. Policy makers, health care providers and families need to do much more to tackle the growing obesity epidemic in young people,” he said.

Dr. Brightling was not involved in the study.

The study was supported by the ERS and the European Union’s H2020 research and innovation program. Dr. Longo was a Horizon 2020 Marie-Sklodowska Cure Respire-3 fellow. Dr. Brightling reported no relevant disclosures.

The U.S. Preventive Services Task Force has updated its 2014 statement on screening asymptomatic individuals for chlamydia and gonorrhea infection.

Published online in JAMA, the 2021 version recommends that all sexually active women aged 24 years or younger and at-risk women 25 years or older should be screened for chlamydia and gonorrhea.

As in 2014, the task force made no screening recommendation for men owing to inconclusive evidence of benefit.

With cases of sexually transmitted infections reaching all-time highs, Amy G. Cantor, MD, MPH, of the Pacific Northwest Evidence-based Practice Center at Oregon Health & Science University, Portland, and colleagues noted that chlamydia and gonorrhea are among the most common STIs in this country. According to the Centers for Disease Control and Prevention, 2019 saw approximately 1.8 million reported cases of chlamydia and more than 600,000 of gonorrhea.

In the current analysis of 27 observational and randomized studies comprising 179,515 patients, the USPSTF panel found that, compared with no screening, chlamydia screening was significantly associated with a reduced risk of pelvic inflammatory disease (PID) in young women in 2 out of 4 trials.

The authors cautioned, however, that the magnitude of benefit was relatively small. No studies reported on screening effectiveness in men, except for one reporting rates of epididymitis, and no studies were done on pregnant women for any outcome.

The largest and newest study, the Australian Chlamydia Control Effectiveness Pilot trial of 2018, assessed chlamydia screening against usual care in 180,355 men and women aged 16-29 years in 130 rural Australian primary care clinics. Screening was associated with a reduced risk of hospital-diagnosed PID: the absolute risk was 0.24% for screening versus 0.38% for usual care (unadjusted risk ratio, 0.6; 95% confidence interval, 0.4-1.0). It was not, however, significantly associated with a reduced risk of clinic-diagnosed PID, with an absolute risk of 0.45% versus 0.39% (RR, 1.1; 95% CI, 0.7-18). Nor did it correlate with a risk reduction for clinic-diagnosed epididymitis: 0.26% vs. 0.27% (RR, 0.9; 95% CI, 0.6-1.4).

While risk prediction criteria apart from age were only minimally accurate, testing for asymptomatic chlamydial and gonococcal infections was highly accurate at most anatomical sites, including urine and self-collected specimens, the investigators observed. Age 22 years or younger alone versus multi-item risk criteria demonstrated similar discrimination in a study that included symptomatic and asymptomatic women.

Sensitivity of chlamydial testing was similar at endocervical (89%-100%) and self- and clinician-collected vaginal (90%-100%) sites for women and at meatal (100%), urethral (99%), and rectal (92%) sites for men. It was lower, however, at pharyngeal sites (69.2%) for men who have sex with men (MSM).

Sensitivity of gonococcal testing was 89% or greater for all anatomical samples. False-positive and false-negative testing rates were low across anatomical sites and collection methods.

“Effectiveness of screening in men and during pregnancy, optimal screening intervals, and adverse effects of screening require further evaluation, Dr. Cantor and associates concluded.

In an accompanying editorial, Jeanne Marrazzo, MD, MPH, and Jodie Dionne-Odom, MD, MSPH, of the division of infectious diseases at the University of Alabama at Birmingham, called the guidelines “timely” and “powerful agents of change” that “influence a wide spectrum of health-based metrics, from quality assurance measures to criteria for financial reimbursement.”

They pointed out that men who have sex with men are experiencing historically high rates of gonorrhea, with most infections occurring extragenitally at the pharynx or rectum. In 2019 CDC data, MSM had substantially higher rates of gonorrhea than men who had sex only with women. They recommended that guidelines for men consider STI risk because of sexual relations with men, women, or both.

“Comprehensive screening guidelines for common STIs like chlamydia and gonorrhea could incorporate the limited evidence base for MSM, whether it is regular practice or not,” they wrote, with the same approach for women who have sex with women but may be at risk for chlamydia, particularly if they also have sex with men.

In their view, these latest guidelines appropriately prioritize high-level clinically based data. They pointed, however, to recent progress in understanding the pathogenesis of upper reproductive tract infection in women and the sexual networks behind the current resurgence of STIs in the United States in the failure to manage exposed sex partners.

“Considering these critical advances in the evolution of clinic-based screening guidelines is a work in progress,” they wrote, “the dialogue among basic scientists, clinical trial investigators, and public health professionals to inform the next version of updated USPSTF chlamydia and gonorrhea screening guidelines should start now.”

In the opinion of Jennifer L. Reed, MD, MS, a professor of pediatrics and an emergency medicine physician at Cincinnati Children’s Hospital Medical Center and not involved in the updated statement, the recommendations are very reasonable. “The highest rates of infection occur in females 15-24 years of age, and therefore asymptomatic screening for chlamydia and gonorrhea is imperative at least annually or more often if they are high risk,” she said in an interview.

“I would hope that providers increase their asymptomatic screening as a result of these recommendations and highly consider it in the younger men,” Dr. Reed added. “I see a very high rate of gonorrhea and chlamydia infections.” Her center is studying the implementation of gonorrhea and chlamydia asymptomatic screening for adolescents in the pediatric emergency department, a high-risk patient population that will benefit from STI screening opportunities in nontraditional settings.

This research was funded by the Agency for Healthcare Research and Quality and the Department of Health & Human Services under a contract to support the USPSTF. One statement coauthor reported personal fees from Insmed, Paratek, RedHill, and Spero, as well as grants from Insmed. No other disclosures were reported. Dr. Dionne-Odom reported grants from the National Institutes of Health/National Institute of Child Health and Development. Dr. Reed reported a grant from NIH/NICHD for a pragmatic trial of improving STI detection in the pediatric ED.

In the current analysis of 27 observational and randomized studies comprising 179,515 patients, the USPSTF panel found that, compared with no screening, chlamydia screening was significantly associated with a reduced risk of pelvic inflammatory disease (PID) in young women in 2 out of 4 trials.

The authors cautioned, however, that the magnitude of benefit was relatively small. No studies reported on screening effectiveness in men, except for one reporting rates of epididymitis, and no studies were done on pregnant women for any outcome.

The largest and newest study, the Australian Chlamydia Control Effectiveness Pilot trial of 2018, assessed chlamydia screening against usual care in 180,355 men and women aged 16-29 years in 130 rural Australian primary care clinics. Screening was associated with a reduced risk of hospital-diagnosed PID: the absolute risk was 0.24% for screening versus 0.38% for usual care (unadjusted risk ratio, 0.6; 95% confidence interval, 0.4-1.0). It was not, however, significantly associated with a reduced risk of clinic-diagnosed PID, with an absolute risk of 0.45% versus 0.39% (RR, 1.1; 95% CI, 0.7-18). Nor did it correlate with a risk reduction for clinic-diagnosed epididymitis: 0.26% vs. 0.27% (RR, 0.9; 95% CI, 0.6-1.4).

While risk prediction criteria apart from age were only minimally accurate, testing for asymptomatic chlamydial and gonococcal infections was highly accurate at most anatomical sites, including urine and self-collected specimens, the investigators observed. Age 22 years or younger alone versus multi-item risk criteria demonstrated similar discrimination in a study that included symptomatic and asymptomatic women.

Sensitivity of chlamydial testing was similar at endocervical (89%-100%) and self- and clinician-collected vaginal (90%-100%) sites for women and at meatal (100%), urethral (99%), and rectal (92%) sites for men. It was lower, however, at pharyngeal sites (69.2%) for men who have sex with men (MSM).

Sensitivity of gonococcal testing was 89% or greater for all anatomical samples. False-positive and false-negative testing rates were low across anatomical sites and collection methods.

“Effectiveness of screening in men and during pregnancy, optimal screening intervals, and adverse effects of screening require further evaluation, Dr. Cantor and associates concluded.

In an accompanying editorial, Jeanne Marrazzo, MD, MPH, and Jodie Dionne-Odom, MD, MSPH, of the division of infectious diseases at the University of Alabama at Birmingham, called the guidelines “timely” and “powerful agents of change” that “influence a wide spectrum of health-based metrics, from quality assurance measures to criteria for financial reimbursement.”

They pointed out that men who have sex with men are experiencing historically high rates of gonorrhea, with most infections occurring extragenitally at the pharynx or rectum. In 2019 CDC data, MSM had substantially higher rates of gonorrhea than men who had sex only with women. They recommended that guidelines for men consider STI risk because of sexual relations with men, women, or both.

“Comprehensive screening guidelines for common STIs like chlamydia and gonorrhea could incorporate the limited evidence base for MSM, whether it is regular practice or not,” they wrote, with the same approach for women who have sex with women but may be at risk for chlamydia, particularly if they also have sex with men.

In their view, these latest guidelines appropriately prioritize high-level clinically based data. They pointed, however, to recent progress in understanding the pathogenesis of upper reproductive tract infection in women and the sexual networks behind the current resurgence of STIs in the United States in the failure to manage exposed sex partners.

“Considering these critical advances in the evolution of clinic-based screening guidelines is a work in progress,” they wrote, “the dialogue among basic scientists, clinical trial investigators, and public health professionals to inform the next version of updated USPSTF chlamydia and gonorrhea screening guidelines should start now.”

In the opinion of Jennifer L. Reed, MD, MS, a professor of pediatrics and an emergency medicine physician at Cincinnati Children’s Hospital Medical Center and not involved in the updated statement, the recommendations are very reasonable. “The highest rates of infection occur in females 15-24 years of age, and therefore asymptomatic screening for chlamydia and gonorrhea is imperative at least annually or more often if they are high risk,” she said in an interview.

“I would hope that providers increase their asymptomatic screening as a result of these recommendations and highly consider it in the younger men,” Dr. Reed added. “I see a very high rate of gonorrhea and chlamydia infections.” Her center is studying the implementation of gonorrhea and chlamydia asymptomatic screening for adolescents in the pediatric emergency department, a high-risk patient population that will benefit from STI screening opportunities in nontraditional settings.

This research was funded by the Agency for Healthcare Research and Quality and the Department of Health & Human Services under a contract to support the USPSTF. One statement coauthor reported personal fees from Insmed, Paratek, RedHill, and Spero, as well as grants from Insmed. No other disclosures were reported. Dr. Dionne-Odom reported grants from the National Institutes of Health/National Institute of Child Health and Development. Dr. Reed reported a grant from NIH/NICHD for a pragmatic trial of improving STI detection in the pediatric ED.
 

Women cardiologists receive dramatically smaller payments from the U.S. Centers for Medicare & Medicaid Services (CMS) than their male counterparts, new research suggests.

An analysis of 2016 claims data revealed male cardiologists received on average 45% more reimbursement than women in the inpatient setting, with the median payment 39% higher ($62,897 vs. $45,288).

In the outpatient setting, men received on average 62% more annual CMS payments, with the median payment 75% higher ($91,053 vs. $51,975; P < .001 for both).

The difference remained significant after the exclusion of the top and bottom 2.5% of earning physicians and cardiology subspecialties, like electrophysiology and interventional cardiology, with high procedural volumes and greater gender imbalances.

“This is one study among others which demonstrates a wage gap between men and women in medicine in cardiology,” lead author Inbar Raber, MD, Beth Israel Deaconess Medical Center, Boston, said in an interview. “I hope by increasing awareness [and] understanding of possible etiologies, it will enable some sustainable solutions, and those include access to additional support staff and equitable models surrounding parental leave and childcare support.”

The study, published online September 8 in JAMA Cardiology, comes on the heels of a recent cross-sectional analysis that put cardiology at the bottom of 13 internal medicine subspecialties with just 21% female faculty representation and one of only three specialties in which women’s median salaries did not reach 90% of men’s.

The new findings build on a 2017 report that showed Medicare payments to women physicians in 2013 were 55% of those to male physicians across all specialties.  

“It can be disheartening, especially as an early career woman cardiologist, seeing these differences, but I think the responsibility on all of us is to take these observations and really try to understand more deeply why they exist,” Nosheen Reza, MD, from the University of Pennsylvania, Philadelphia, and coauthor of the cross-sectional analysis, told this news organization.

Several factors could be contributing to the disparity, but “it’s not gender discrimination from Medicare,” Dr. Raber said. “The gap in reimbursement is really driven by the types and the volume of charges submitted.”

Indeed, a direct comparison of the three most common inpatient and outpatient billing codes showed no difference in payments between the sexes.

Men, however, submitted 24% more median inpatient charges to CMS than women (1,190 vs. 959), and 94% more outpatient charges (1,685 vs. 870).

Men also submitted slightly more unique billing codes (median inpatient, 10 vs. 9; median outpatient, 11 vs. 8).

Notably, women made up just 13% of the 17,524 cardiologists who received CMS payments in the inpatient setting in 2016 and 13% of the 16,929 cardiologists who did so in the outpatient setting.

Louisiana had the dubious distinction of having the largest gender gap in mean CMS payments, with male cardiologists earning $145,323 (235%) more than women, whereas women cardiologists in Vermont out-earned men by $31,483 (38%).

Overall, male cardiologists had more years in practice than women cardiologists and cared for slightly older Medicare beneficiaries.

Differences in CMS payments persisted, however, after adjustment for years since graduation, physician subspecialty, number of charges, number of unique billing codes, and patient complexity. The resulting β coefficient was -0.06, which translates into women receiving an average of 94% of the CMS payments received by men.

“The first takeaway, if you were really crass and focused on the bottom line, might be: ‘Hey, let me get a few more male cardiologists because they’re going to bring more into the organization.’ But we shouldn’t do that because, unless you link these data with quality outcomes, they’re an interesting observation and hypothesis-generating,” said Sharonne Hayes, MD, coauthor of the 2017 report and professor of cardiovascular medicine at Mayo Clinic in Rochester, Minn., where she has served as director of diversity and inclusion for a decade.

She noted that there are multiple examples that the style of medicine women practice, on average, may be more effective, may be more outcomes based, and may save lives, as suggested by a recent analysis of hospitalized Medicare beneficiaries.

“The gap was not much different, like within 1% or so, but when you take that over the literally millions of Medicare patients cared for each year by hospitalists, that’s a substantial number of people,” Dr. Hayes said. “So, I think we need to take a step back, and we have to include these observations on studies like this and better understand the compensation gaps.”

She pointed out that the present study lacks data on full-time-equivalent status but that female physicians are more likely to work part-time, thus reducing the volume of claims.

Women might also care for different patient populations. “I practice in a women’s heart clinic and take care of [spontaneous coronary artery dissection] SCAD patients where the average age of SCAD is 42. So, the vast majority of patients I see on a day-to-day basis aren’t going to be Medicare age,” observed Dr. Hayes.

The differences in charges might also reflect the increased obligations in nonreimbursed work that women can have, Dr. Raber said. These can be things like mentoring, teaching roles, and serving on committees, which is a hypothesis supported by a 2021 study that showed women physicians spend more time on these “citizenship tasks” than men.

Finally, there could be organizational barriers that affect women’s clinical volumes, including less access to support from health care personnel. Added support is especially important, though, amid a 100-year pandemic, the women agreed.

“Within the first year of the pandemic, we saw women leaving the workforce in droves across all sectors, including medicine, including academic medicine. And, as the pandemic goes on without any signs of abatement, those threats continue to exist and continue to be amplified,” Dr. Reza said.

The groundswell of support surrounding the importance of diversity, equity, and inclusion initiatives across the board has helped bring attention to the issue, she said. Some institutions, including the National Institutes of Health, are making efforts to extend relief to women with young families, caregivers, or those in academic medicine who, for example, need extensions on grants or bridge funding.

“There’s certainly a lot left to do, but I do think within the last year, there’s been an acceleration of literature that has come out, not only pointing out the disparities, but pointing out that perhaps women physicians do have better outcomes and are better liked by their patients and that losing women in the workforce would be a huge detriment to the field overall,” Dr. Reza said.

The new guideline on management of heart failure (HF) from the European Society of Cardiology seemed to bear an asterisk or footnote even before its full unveiling in the early hours of ESC Congress 2021.

The document would offer little new in the arena of HF with preserved ejection fraction (HFpEF), so understandably the fast-approaching presentation of a major HFpEF trial – arguably the conference’s marquee event – would feel to some like the elephant in the room.

“I’d like to highlight this unfortunate timing of the guideline, because it’s an hour or 2 before we hear the full story from EMPEROR-Preserved, which I’m sure will change the guidelines,” Faiez Zannad, MD, PhD, University of Lorraine, Vandoeuvre-Les-Nancy, France, said wryly.

Anticipation of the trial’s full presentation was intense as the ESC congress got underway, in part because the top-line and incomplete message from EMPEROR-Preserved had already been released: Patients with HFpEF treated with the sodium-glucose cotransporter 2 inhibitor empagliflozin (Jardiance, Boehringer Ingelheim/Eli Lilly) showed a significant benefit for the primary endpoint of cardiovascular (CV) death or HF hospitalization.

Although empagliflozin is the first medication to achieve that status in a major HFpEF trial, conspicuously absent from the early announcement were the magnitude of “benefit” and any data. Still, the tantalizing top-line results mean that technically, at least, “we have a drug which is effective in reduced and preserved ejection fraction,” Dr. Zannad said.

But the new guideline, published online Aug. 27, 2021, in the European Heart Journal and comprehensively described that day at the congress, was never really expected to consider results from EMPEROR-Reduced. “These new indications do need to go through the regulatory authorities,” such as the European Medicines Agency and the U.S. Food and Drug Administration, observed Carlos Aguiar, MD, Hospital Santa Cruz, Carnaxide, Portugal.

“It does take some time for the whole process to be concluded and, finally, as physicians, being able to implement it in clinical practice,” Dr. Aguiar said as moderator of press briefing prior to the ESC congress.

The ESC guideline’s next iteration or update could well include an SGLT2 inhibitor recommendation that applies beyond the ejection fraction limits of HFrEF. Still, the document summarized that day reflects a number of pivotal concepts with profound treatment implications. Among them are the field’s latest paradigm for medical therapy of HFrEF and the increasingly accepted division of traditional HFpEF into two entities: HF with mildly reduced ejection fraction (HFmrEF); and HFpEF, with its left ventricular ejection fraction (LVEF) threshold raised to 50%.

In fact, HFmrEF in the new document is a drug-therapy indication that barely existed a few years ago but grew in prominence after secondary findings from trials like TOPCAT for spironolactone and PARAGON-HF for sacubitril-valsartan (Entresto, Novartis), an angiotensin-receptor/neprilysin inhibitor (ARNI). Still, the HFmrEF recommendations come with different class and level-of-evidence designations.

Those new guideline features and others in the realm of pharmacologic therapy were summarized by the document’s authors at the 2021 Heart Failure Association of the European Society of Cardiology (ESC-HFA) meeting, and covered at the time by this news organization

The ‘fantastic four’

One of the document’s central recommendations specifies which contemporary drug classes should be initiated, and when, in patients with HFrEF. An ACE inhibitor or ARNI, a beta-blocker, a mineralocorticoid receptor antagonist (MRA), and an SGLT2 inhibitor collectively earned a class I recommendation, “given the importance of these key HFrEF therapies, some of which have been shown to improve outcomes within a month of initiation,” observed Roy S. Gardner, MBChB, MD.

An agent from each of the four classes is to be “commenced and up-titrated as quickly and as safely as possible, whilst using the lowest effective dose of loop diuretic to relieve congestion,” said Dr. Gardner, from Golden Jubilee National Hospital, Clydebank, Scotland, when presenting the full HFrEF portion of the guidelines.

The oral soluble guanylate-cyclase receptor stimulator vericiguat (Verquvo, Merck), which recently emerged from the VICTORIA trial as a modest success for patients with HFrEF and a previous HF hospitalization, gained a class IIb recommendation.

The document’s “simplified algorithm” for managing such patients overall and the advent of SGLT2 inhibitors are new twists in ESC guidelines for HF. But the way the four drug classes are started in patients is key and could take some practitioners time to get used to. There is no prespecified order of initiation.

“We’ve left the door open for clinicians to evaluate the evidence to make sure these four drugs are started, and to tailor how to do it according to the patient,” based on clinical considerations such as blood pressure or renal function, said Theresa A. McDonagh, MD, King’s College London, cochair of the guideline task force.

“The SGLT2 inhibitor trials were done on top of therapy with ACE inhibitors or ARNI, beta-blockers, and MRAs, so some people no doubt will choose to follow a sequenced approach,” Dr. McDonagh said. Other practitioners will consider each patient and attempt to get all four started “as quickly and safely as possible based on the phenotype.”

Importantly, clinicians “should not wait for weeks, months, or years until you have the four drugs in the patient, but you should do this within weeks,” cautioned Johann Bauersachs, MD, Hannover (Germany) Medical School, a discussant for the guideline presentation who is listed as a reviewer on the document.

Although angiotensin-receptor blockers (ARBs) and ACE inhibitors are sometimes thought of as interchangeable, the new guideline does not give them the same weight. “The angiotensin-receptor blocker valsartan is a constituent of the ARNI,” Dr. McDonagh noted. “So, the place of ARBs in heart failure has been downgraded in HFrEF. They are really for those who are intolerant of an ACE inhibitor or an ARNI.”

In practice, ARBs are likely to be used as first-line therapy in some circumstances, observed Dr. Bauersachs. They are “the default option in, unfortunately, many low-income countries that may not afford sacubitril-valsartan. And I know that there are many of them.”
 

Tweaks to device recommendations

The new document contains several new wrinkles in the recommendations for HF device therapy, which should usually be considered only if still appropriate after at least 3 months of optimal medical therapy, Dr. Gardner said.

For example, use of an implantable cardioverter-defibrillator (ICD) has been demoted from its previous class I recommendation to class II, level of evidence A, in patients with nonischemic cardiomyopathy “in light of the data from the DANISH study,” Dr. Gardner said.

The 2016 DANISH trial was noteworthy for questioning the survival benefits of ICDs in patients with nonischemic cardiomyopathy, whether or not they were also receiving cardiac resynchronization therapy (CRT).

The new document also puts greater emphasis on a range of specific CRT patient-selection criteria. Beyond the conventional recommended standards of an LVEF of 35% or less, QRS of at least 150 ms, and left-bundle-branch block on optimal meds, consideration can be given to CRT if the QRS is only 130 ms or greater. “And where it’s appropriate to do so, an ICD could be an option,” Dr. Gardner said.

It also recommends CRT as a replacement for right ventricular pacing in patients with high-degree atrioventricular block. “And this, for the first time, includes patients with atrial fibrillation,” he said. “The previous indications for CRT were in individuals in sinus rhythm.”

The new document recommends that HF in any patient be classified as HFrEF, defined by an LVEF of ≤40%; HFmrEF, defined by an LVEF of 41%-49%; or HFpEF, defined by an LVEF of at least 50%. “Importantly, for all forms, the presence of the clinical syndrome of heart failure is a prerequisite,” observed Carolyn S.P. Lam, MBBS, PhD, Duke-NUS Graduate Medical School, Singapore, at the presentation.

In a critical update from previous guidelines, the term HF with “mid-range” ejection fraction was replaced by the term specifying “mildly reduced” ejection fraction, Dr. Lam noted. The shift retains the acronym but now reflects growing appreciation that HFmrEF patients can benefit from treatments also used in HFrEF, including ACE inhibitors, ARBs, beta-blockers, MRAs, and sacubitril-valsartan, she said.

Support for that relationship comes largely from post hoc subgroup analyses of trials that featured some patients with LVEF 40%-49%. That includes most HFpEF trials represented in the guideline document, but also EMPEROR-Preserved, which saw gains for the primary outcome across the entire range of LVEF above 40%.

The LVEF-based definitions are consistent with a recent HF classification proposal endorsed by the ESC and subspecialty societies in Europe, North America, Japan, India, Australia, New Zealand, and China.

The document doesn’t update recommendations for HFpEF, in which “no treatment has been shown to convincingly reduce mortality or morbidity,” Dr. Lam observed. Still, she noted, the guideline task force “acknowledges that treatment options for HFpEF are being revised even as the guidelines have been published.”

That could be a reference to empagliflozin in EMPEROR-Preserved, but it also refers to the strikingly broad wording of an expanded indication for sacubitril-valsartan in the United States – “to reduce the risk of cardiovascular death and hospitalization for heart failure in adult patients with chronic heart failure” – without specific restrictions on the basis of LVEF. The new indication was announced in early 2021, too late to be considered in the new guidelines.
 

Whither LVEF-based definitions?

During discussion after the guideline presentation, Dr. Zannad speculated on the future of HF classifications based on ventricular function, given trial evidence in recent years that some agents – notably spironolactone, sacubitril-valsartan, and now, apparently, empagliflozin – might be effective in HFpEF as well as HFrEF.

Will the field continue with “LVEF-centric” distinctions across the range of HF, or transition to “some definition in which drug therapies can be used independently across the full spectrum of ejection fraction?” Dr. Zannad posed.

“I think we need to wait and see what some of these trials with the SGLT2 inhibitors are going to show in heart failure with preserved ejection fraction,” Dr. McDonagh replied. “And I think that will be a step for the next guideline, completely redefining heart failure.”

The document would offer little new in the arena of HF with preserved ejection fraction (HFpEF), so understandably the fast-approaching presentation of a major HFpEF trial – arguably the conference’s marquee event – would feel to some like the elephant in the room.

“I’d like to highlight this unfortunate timing of the guideline, because it’s an hour or 2 before we hear the full story from EMPEROR-Preserved, which I’m sure will change the guidelines,” Faiez Zannad, MD, PhD, University of Lorraine, Vandoeuvre-Les-Nancy, France, said wryly.

Anticipation of the trial’s full presentation was intense as the ESC congress got underway, in part because the top-line and incomplete message from EMPEROR-Preserved had already been released: Patients with HFpEF treated with the sodium-glucose cotransporter 2 inhibitor empagliflozin (Jardiance, Boehringer Ingelheim/Eli Lilly) showed a significant benefit for the primary endpoint of cardiovascular (CV) death or HF hospitalization.

Although empagliflozin is the first medication to achieve that status in a major HFpEF trial, conspicuously absent from the early announcement were the magnitude of “benefit” and any data. Still, the tantalizing top-line results mean that technically, at least, “we have a drug which is effective in reduced and preserved ejection fraction,” Dr. Zannad said.

But the new guideline, published online Aug. 27, 2021, in the European Heart Journal and comprehensively described that day at the congress, was never really expected to consider results from EMPEROR-Reduced. “These new indications do need to go through the regulatory authorities,” such as the European Medicines Agency and the U.S. Food and Drug Administration, observed Carlos Aguiar, MD, Hospital Santa Cruz, Carnaxide, Portugal.

“It does take some time for the whole process to be concluded and, finally, as physicians, being able to implement it in clinical practice,” Dr. Aguiar said as moderator of press briefing prior to the ESC congress.

The ESC guideline’s next iteration or update could well include an SGLT2 inhibitor recommendation that applies beyond the ejection fraction limits of HFrEF. Still, the document summarized that day reflects a number of pivotal concepts with profound treatment implications. Among them are the field’s latest paradigm for medical therapy of HFrEF and the increasingly accepted division of traditional HFpEF into two entities: HF with mildly reduced ejection fraction (HFmrEF); and HFpEF, with its left ventricular ejection fraction (LVEF) threshold raised to 50%.

In fact, HFmrEF in the new document is a drug-therapy indication that barely existed a few years ago but grew in prominence after secondary findings from trials like TOPCAT for spironolactone and PARAGON-HF for sacubitril-valsartan (Entresto, Novartis), an angiotensin-receptor/neprilysin inhibitor (ARNI). Still, the HFmrEF recommendations come with different class and level-of-evidence designations.

Those new guideline features and others in the realm of pharmacologic therapy were summarized by the document’s authors at the 2021 Heart Failure Association of the European Society of Cardiology (ESC-HFA) meeting, and covered at the time by this news organization

The ‘fantastic four’

One of the document’s central recommendations specifies which contemporary drug classes should be initiated, and when, in patients with HFrEF. An ACE inhibitor or ARNI, a beta-blocker, a mineralocorticoid receptor antagonist (MRA), and an SGLT2 inhibitor collectively earned a class I recommendation, “given the importance of these key HFrEF therapies, some of which have been shown to improve outcomes within a month of initiation,” observed Roy S. Gardner, MBChB, MD.

An agent from each of the four classes is to be “commenced and up-titrated as quickly and as safely as possible, whilst using the lowest effective dose of loop diuretic to relieve congestion,” said Dr. Gardner, from Golden Jubilee National Hospital, Clydebank, Scotland, when presenting the full HFrEF portion of the guidelines.

The oral soluble guanylate-cyclase receptor stimulator vericiguat (Verquvo, Merck), which recently emerged from the VICTORIA trial as a modest success for patients with HFrEF and a previous HF hospitalization, gained a class IIb recommendation.

The document’s “simplified algorithm” for managing such patients overall and the advent of SGLT2 inhibitors are new twists in ESC guidelines for HF. But the way the four drug classes are started in patients is key and could take some practitioners time to get used to. There is no prespecified order of initiation.

“We’ve left the door open for clinicians to evaluate the evidence to make sure these four drugs are started, and to tailor how to do it according to the patient,” based on clinical considerations such as blood pressure or renal function, said Theresa A. McDonagh, MD, King’s College London, cochair of the guideline task force.

“The SGLT2 inhibitor trials were done on top of therapy with ACE inhibitors or ARNI, beta-blockers, and MRAs, so some people no doubt will choose to follow a sequenced approach,” Dr. McDonagh said. Other practitioners will consider each patient and attempt to get all four started “as quickly and safely as possible based on the phenotype.”

Importantly, clinicians “should not wait for weeks, months, or years until you have the four drugs in the patient, but you should do this within weeks,” cautioned Johann Bauersachs, MD, Hannover (Germany) Medical School, a discussant for the guideline presentation who is listed as a reviewer on the document.

Although angiotensin-receptor blockers (ARBs) and ACE inhibitors are sometimes thought of as interchangeable, the new guideline does not give them the same weight. “The angiotensin-receptor blocker valsartan is a constituent of the ARNI,” Dr. McDonagh noted. “So, the place of ARBs in heart failure has been downgraded in HFrEF. They are really for those who are intolerant of an ACE inhibitor or an ARNI.”

In practice, ARBs are likely to be used as first-line therapy in some circumstances, observed Dr. Bauersachs. They are “the default option in, unfortunately, many low-income countries that may not afford sacubitril-valsartan. And I know that there are many of them.”
 

Tweaks to device recommendations

The new document contains several new wrinkles in the recommendations for HF device therapy, which should usually be considered only if still appropriate after at least 3 months of optimal medical therapy, Dr. Gardner said.

For example, use of an implantable cardioverter-defibrillator (ICD) has been demoted from its previous class I recommendation to class II, level of evidence A, in patients with nonischemic cardiomyopathy “in light of the data from the DANISH study,” Dr. Gardner said.

The 2016 DANISH trial was noteworthy for questioning the survival benefits of ICDs in patients with nonischemic cardiomyopathy, whether or not they were also receiving cardiac resynchronization therapy (CRT).

The new document also puts greater emphasis on a range of specific CRT patient-selection criteria. Beyond the conventional recommended standards of an LVEF of 35% or less, QRS of at least 150 ms, and left-bundle-branch block on optimal meds, consideration can be given to CRT if the QRS is only 130 ms or greater. “And where it’s appropriate to do so, an ICD could be an option,” Dr. Gardner said.

It also recommends CRT as a replacement for right ventricular pacing in patients with high-degree atrioventricular block. “And this, for the first time, includes patients with atrial fibrillation,” he said. “The previous indications for CRT were in individuals in sinus rhythm.”

The new document recommends that HF in any patient be classified as HFrEF, defined by an LVEF of ≤40%; HFmrEF, defined by an LVEF of 41%-49%; or HFpEF, defined by an LVEF of at least 50%. “Importantly, for all forms, the presence of the clinical syndrome of heart failure is a prerequisite,” observed Carolyn S.P. Lam, MBBS, PhD, Duke-NUS Graduate Medical School, Singapore, at the presentation.

In a critical update from previous guidelines, the term HF with “mid-range” ejection fraction was replaced by the term specifying “mildly reduced” ejection fraction, Dr. Lam noted. The shift retains the acronym but now reflects growing appreciation that HFmrEF patients can benefit from treatments also used in HFrEF, including ACE inhibitors, ARBs, beta-blockers, MRAs, and sacubitril-valsartan, she said.

Pediatric urine sampling should be used more frequently than current guidelines suggest for ruling out urinary tract infection (UTI), according to a systematic review and meta-analysis of diagnostic test accuracy studies in ambulatory care (Ann Fam Med 2021;19:437-46).

“Urine sampling is often restricted to children with clinical features such as pain while urinating, frequent urination or children presenting with fever without any abnormalities found on clinical examination,” said lead author Jan Y. Verbakel, MD, PhD, from the University of Leuven (Belgium) in an interview. “Our study findings suggest that, in children, pain while urinating or frequent urination are less accurate than in adults and increase the probability of UTI only moderately.”

Urine sampling “should be applied more broadly in ambulatory care, given that appropriate sampling techniques are available,” he and his coauthors advised in the paper.

Methods and results

The analysis included 35 studies, involving a total of 78,427 patients, which provided information on 58 clinical features and 6 prediction rules of UTI, compared with urine culture. For urine sampling, most studies used catheterization (n = 23), suprapubic aspiration (n = 17), or midstream catch (n = 14), and fewer studies used clean catch (n = 7), bag specimens (n = 5), or diaper pads (n = 2).

The study showed that only three features substantially decreased the likelihood of UTI: being circumcised, the presence of stridor, and the presence of diaper rash. “In febrile children, finding an apparent source of infection decreased the probability of UTI; however, this was not useful for ruling out UTI by itself,” the authors noted.

Additionally, they found that red flags for UTI were cloudy or malodorous urine, hematuria, no fluid intake, suprapubic tenderness, and loin tenderness.

Study implications

“We recommend to sample urine in children that have one or more features that increase the probability of UTI … and less so pain while urinating, frequent urination, urgency, bed wetting, or previous UTI history,” said Dr. Verbakel, who is also a researcher at the University of Oxford (England).

In terms of prediction rules, the analysis showed the Diagnosis of Urinary Tract Infection in Young Children (DUTY) score, Gorelick Scale score, and UTIcalc might be useful to identify which children should have urine sampling, the authors stated in the paper.

Specifically, a DUTY clean-catch score of less than one point was useful for ruling out UTI in children aged less than 5 years, and in girls aged less than 3 years with unexplained fever. The Gorelick Scale score was useful for ruling out UTI when less than two of five variables were present.

“The present meta-analyses confirm that few clinical features are useful for diagnosing or ruling out UTI without further urine analysis. Signs and symptoms combined in a clinical prediction rule, such as with the DUTY or UTIcalc score, might increase accuracy for ruling out UTI; however, these should be validated externally,” Dr. Verbakel said in an interview.

Is urine sampling guideline too broad?

Commenting on the new paper, Martin Koyle, MD, former division chief of urology at the Hospital for Sick Children and professor of surgery at the University of Toronto, expressed concern that unexplained fever is not included as a “differentiating” red flag.

“Many contemporary guidelines define fever as an important diagnostic symptom, as the goal truly is to differentiate lower urinary tract from actual kidney infection, the latter thought to be more important for severity of illness, and potential for developing kidney damage,” he said in an interview. “It begs the question as to which nonfebrile patients who don’t have symptoms related to the respiratory tract for instance [for example, stridor], should be under suspicion for an afebrile urinary tract infection, and have their urine sampled. This paper does not answer that question.”

Dr. Koyle added that an overly broad guideline for urine sampling could come at a cost, and he raised the following questions.

“Will there be an overdiagnosis based on urines alone? Will this lead to overtreatment, often unnecessary, just because there is a positive urine specimen or asymptomatic bacteriuria? Will overtreatment lead to resistant bacteria and side effects related to antibiotics? Will such treatment actually prevent clinical illness and/or renal damage?”

The study authors and Dr. Koyle reported no conflicts of interest.

Signs and symptoms combined in a clinical prediction rule, such as with the DUTY or UTIcalc score, might increase accuracy for ruling out UTI; however, these should be validated externally,” Dr. Verbakel said in an interview.

Is urine sampling guideline too broad?

Commenting on the new paper, Martin Koyle, MD, former division chief of urology at the Hospital for Sick Children and professor of surgery at the University of Toronto, expressed concern that unexplained fever is not included as a “differentiating” red flag.

“Many contemporary guidelines define fever as an important diagnostic symptom, as the goal truly is to differentiate lower urinary tract from actual kidney infection, the latter thought to be more important for severity of illness, and potential for developing kidney damage,” he said in an interview. “It begs the question as to which nonfebrile patients who don’t have symptoms related to the respiratory tract for instance [for example, stridor], should be under suspicion for an afebrile urinary tract infection, and have their urine sampled. This paper does not answer that question.”

Dr. Koyle added that an overly broad guideline for urine sampling could come at a cost, and he raised the following questions.

“Will there be an overdiagnosis based on urines alone? Will this lead to overtreatment, often unnecessary, just because there is a positive urine specimen or asymptomatic bacteriuria? Will overtreatment lead to resistant bacteria and side effects related to antibiotics? Will such treatment actually prevent clinical illness and/or renal damage?”

The study authors and Dr. Koyle reported no conflicts of interest.

A new study may help doctors assess the long-term risk for major bleeding if anticoagulation for unprovoked venous thromboembolisms (VTE) is continued beyond 3-6 months.

The meta-analysis of data from 27 studies with 17,202 patients was published in the Annals of Internal Medicine. According to two of the paper’s coauthors, Faizan Khan, MSc, and Marc A. Rodger, MD, it “provides best available estimates of long-term bleeding risk with different anticoagulants in patients with unprovoked VTE,” including subgroups at increased risk.

Patients at increased risk for major bleeding include those who are older; those using antiplatelet therapy; and patients with kidney disease, a history of bleeding, or anemia, noted the coauthors, who work for the Ottawa Hospital Research Institute.

The researchers focused on randomized controlled trials (RCTs) and prospective cohort studies that reported major bleeding among patients with a first unprovoked or weakly provoked VTE who received oral anticoagulation for at least 6 months beyond an initial anticoagulant treatment course of at least 3 months.

The investigators analyzed data from 14 RCTs and 13 cohort studies. In all, 9,982 patients received a vitamin K antagonist (VKA), and 7,220 received a direct oral anticoagulant (DOAC).

The incidence of major bleeding per 100 person-years was 1.7 events with VKAs, compared with 1.1 events with DOACs. The researchers estimated that the 5-year cumulative incidence of major bleeding with VKAs was 6.3%. The available data for DOACs were insufficient to estimate the incidence of major bleeding beyond 1 year.

“This information can help clinicians counsel patients and inform shared decision-making about extended therapy,” the researchers said.

Risks of serious bleeding ‘not trivial’

Margaret Fang, MD, with the University of California, San Francisco, agreed that the study can help clinicians and patients weigh the risks of extended anticoagulation for common types of VTE.

The study also “highlights that the risks of serious bleeding are not trivial” and points out gaps in the literature regarding the long-term use of DOACs for extended VTE therapy, Dr. Fang said.

Better ways to predict which patients will develop bleeding on anticoagulants are needed, Dr. Fang added. “It will also be important to establish which of the various therapies for preventing recurrent VTE – full dose versus lowered dose, or even aspirin – has the best balance of safety and efficacy,” she said.

‘Standardized approach’ for identifying high-risk patients lacking

Clinical practice guidelines recommend indefinite anticoagulation for an unprovoked VTE, except when patients are at high risk of bleeding, the authors noted. But clinicians lack a “standardized approach to identify patients at high risk of bleeding,” Mr. Khan and Dr. Rodger said. “Evidence from randomized trials on net long-term benefit of extended therapy is limited, and current guideline recommendations are largely based on expert consensus opinion. Major bleeding events are two to three times more likely to be fatal than recurrent VTE events, so extended therapy is not always associated with a net mortality benefit, particularly in patients at low risk of recurrent VTE or high risk of bleeding.”

The analysis indicates that there is “a clinically meaningful difference in long-term risk for anticoagulant-related major bleeding among patients with a first unprovoked VTE stratified according to presence or absence of the following risk factors: age older than 65 years, creatinine clearance less than 50 mL/min, history of bleeding, concomitant use of antiplatelet therapy, and hemoglobin level less than 100 g/L,” the authors said.

For example, the researchers found that the incidence of major bleeding was higher among those older than 65 years, compared with younger patients (incidence rate ratio, 1.84 with VKAs and 2.92 with DOACs), and among those with creatinine clearance less than 50 mL/min (IRR, 2.83 with VKAs and 3.71 with DOACs).

The case-fatality rate of major bleeding was 8.3% with VKAs and 9.7% with DOACs.

The study received funding from the Canadian Institutes of Health Research. Some of the coauthors are employees of or have financial ties to pharmaceutical companies. Mr. Khan, Dr. Rodger, and Dr. Fang had no relevant disclosures.

Following a 2-year investigation, the U.S. government has filed suit against the University of Pittsburgh Medical Center (UPMC), University of Pittsburgh Physicians (UPP), and James Luketich, MD, for billing related to concurrent surgeries performed by the long-time chair of cardiothoracic surgery.

The lawsuit alleges that UPMC “knowingly allowed” Dr. Luketich to “book and perform three surgeries at the same time, to miss the surgical time outs at the outset of those procedures, to go back-and-forth between operating rooms and even hospital facilities while his surgical patients remain under general anesthesia...”

UPMC, the lawsuit claims, also allowed Dr. Luketich to falsely attest that “he was with his patients throughout the entirety of their surgical procedures or during all ‘key and critical’ portions of those procedures and to unlawfully bill Government Health Benefit Programs for those procedures, all in order to increase surgical volume, maximize UPMC and UPP’s revenue, and/or appease Dr. Luketich.”

These practices violate the statutes and regulations governing the defendants, including those that prohibit “teaching physicians” like Dr. Luketich from performing and billing the U.S. for concurrent surgeries, the Department of Justice said in news release.

The Justice Department contends the defendants “knowingly submitted hundreds of materially false claims for payment” to Medicare, Medicaid, and other government programs over the past 6 years.

“The laws prohibiting ‘concurrent surgeries’ are in place for a reason: To protect patients and ensure they receive appropriate and focused medical care,” Stephen R. Kaufman, Acting U.S. Attorney for the Western District of Pennsylvania, said in the release. 

According to the lawsuit, “some of Dr. Luketich’s patients were forced to endure additional surgical procedures and/or extended hospital stays as a result of his unlawful conduct. Numerous patients developed painful pressure ulcers. A few were diagnosed with compartment syndrome. And at least two had to undergo amputations.”

The allegations were originally brought forward under the federal False Claims Act’s whistleblower provisions by Jonathan D’Cunha, MD, PhD, who worked closely with Dr. Luketich from 2012 to 2019 and now chairs the department of cardiothoracic surgery at the Mayo Clinic, Phoenix.

The charges cited in the lawsuit include three counts of violating the False Claims Act, one count of unjust enrichment, and one count of payment by mistake.

The 56-page lawsuit includes numerous case examples and cites an October 2015 Boston Globe Spotlight Team report on the safety of running concurrent operations, which reportedly prompted UPMC to reevaluate its policies and identify physicians or departments in potential violation.

Hospital officials met with Dr. Luketich in March 2016 and devised a “plan” to ensure his availability and “compliance with concurrency rules,” it alleges, but also highlights an email that notes “continued problems” with Dr. Luketich’s schedule.

“UPMC has persistently ignored or minimized complaints by employees and staff regarding Dr. Luketich, his hyper-busy schedule, his refusal to delegate surgeries and surgical tasks” and “protected him from meaningful sanction; refused to curtail his surgical practice; and continued to allow Dr. Luketich to skirt the rules and endanger his patients,” according to the lawsuit.

The suit notes that Dr. Luketich is one of UPMC and UPP’s highest sources of revenue and that UPMC advertises him as a “life-saving pioneer” who routinely performs dramatic, last-ditch procedures on patients who are otherwise hopeless.

In response to an interview request from this news organization, a UPMC spokesperson wrote: “As the government itself concedes in its complaint, many of Dr. Luketich’s surgical patients are elderly, frail, and/or very ill. They include the ‘hopeless’ patients ... who suffer from chronic illness or metastatic cancer, and/or have extensive surgical histories and choose UPMC and Dr. Luketich when other physicians and health care providers have turned them down.”

“Dr. Luketich always performs the most critical portions of every operation he undertakes,” the spokesperson said, adding that no law or regulation prohibits overlapping surgeries or billing for those surgeries, “let alone surgeries conducted by teams of surgeons like those led by Dr. Luketich.”

“The government’s claims are, rather, based on a misapplication or misinterpretation of UPMC’s internal policies and [Centers for Medicare & Medicaid Services] guidance, neither of which can support a claim for fraudulent billing. UPMC and Dr. Luketich plan to vigorously defend against the government’s claims,” the spokesperson concluded. 

The claims asserted against the defendants are allegations only; there has been no determination of liability. The government is seeking three times the amount of actual damages suffered as a result of the alleged false claims and/or fraud; a sum of $23,331 (or the maximum penalty, whichever is greater) for each false claim submitted by UPMC, UPP, and/or Dr. Luketich; and costs and expenses associated with the civil suit.

Although enrollment into lung cancer clinical trials fell during the early months of the COVID-19 pandemic, it increased after a number of mitigation strategies were introduced.

These strategies should now be maintained, say experts, in order to improve enrollment and access to trials and to ensure that trials are more pragmatic and streamlined.

These were the findings from a survey sent to 173 sites of clinical trials in 45 countries around the world. The findings were presented recently at the World Conference on Lung Cancer (WCLC) 2021. The meeting and the survey were organized by the International Association for the Study of Lung Cancer (IASLC).

Responses to the survey revealed that enrollment into lung cancer trials fell by 43% during the early months of the pandemic. Patients stopped attending clinics, and some trials were suspended.

Patients were less willing to visit clinical trial sites, and lockdown restrictions made travel difficult.

Organizers of clinical trials responded by implementing mitigation strategies, such as changing monitoring requirements, increasing use of telehealth, and using local non-study facilities for laboratory and radiology services.

These measures led to an increase in trial enrollment toward the end of 2020, the survey results show.

“The COVID-19 pandemic created many challenges [that led to] reductions in lung cancer clinical trial enrollment,” commented study presenter Matthew P. Smeltzer, PhD, from the Division of Epidemiology, Biostatistics, and Environmental Health, University of Memphis.

The employment of mitigation strategies allowed the removal of “barriers,” and although the pandemic “worsened, trial enrollment began to improve due in part to these strategies,” Dr. Smeltzer said.

Many of these measures were successful and should be maintained, he suggested. Strategies include allowing telehealth visits, performing testing at local laboratories, using local radiology services, mailing experimental agents “where possible,” and allowing flexibility in trial schedules.

This is a “very important” study, commented Marina Garassino, MD, professor of medicine, hematology, and oncology, the University of Chicago Medicine, in her discussion of the abstract.

Irrespective of the pandemic, the regulation and the bureaucracy of clinical trials hinder participation by patients and physicians, she said.

Many of the mitigation strategies highlighted by the survey were similar to recommendations on the conduct of clinical trials published by the American Society of Clinical Oncology during the pandemic. Those recommendations emphasize the use of telehealth and offsite strategies to help with patient monitoring, she noted.

The findings from the survey show that it is possible to conduct more “streamlined and pragmatic trials,” she said.

“More flexible approaches should be approved by the sponsors of clinical trials and global regulatory bodies,” she added.

However, she expressed concern that “with the telehealth visits, we can create some disparities.”

“We have to remember that lung cancer patients are sometimes a very old population, and they are not digitally evolved,” she commented.

Commenting on Twitter, Jennifer C. King, PhD, chief scientific officer at the GO2 Foundation for Lung Cancer, in Washington, D.C., agreed that many of the mitigation strategies identified in the study “are good for patients all of the time, not just during a pandemic.”

Impact on lung cancer clinical trials

The survey, which included 64 questions, was intended to assess the impact of the COVID pandemic on lung cancer clinical trials.

Most of the survey responses came from sites in Europe (37.6%); 21.4% came from Asia, 13.3% came from the United States, and 7.5% came from Canada.

The team found that enrollment into lung cancer trials declined by 43% in 2020 compared to 2019, at an incidence rate ratio of 0.57 (P = .0115).

The largest decreases in enrollment were between April and August 2020, Dr. Smeltzer noted. However, in the last quarter of 2020 (October to December), the differences in enrollment were significantly smaller (P = .0160), despite a marked increase in global COVID-19 cases per month, he added.

The most common challenges faced by clinical trial sites during the pandemic were the following: There were fewer eligible patients (cited by 67% of respondents); compliance protocol was worse (61%); trials were suspended (60%); there was a lack of research staff (48%); and there were institutional closures (39%).

Regarding patient-related challenges, 67% of sites cited less willingness to visit the site. Other challenges included less ability to travel (cited by 60%), reduced access to the trial site (52%), quarantining because of exposure to COVID-19 (40%), and SARS-CoV-2 infection (26%).

Concerns of patients included the following: Fear of SARS-CoV-2 infection, which was cited by 83%; travel restrictions (47%); securing transportation (38%); and access to the laboratory/radiology services (14%).

“Patient willingness to visit the site was a consistent barrier reported across Europe, the U.S., and Canada,” said Dr. Smeltzer, although the effect was smaller in North America, he added.

Regarding mitigation strategies that were employed during the pandemic to combat the challenges and concerns, the team found that the most common measure was the modification of monitoring requirements, used by 44% of sites.

This was followed by the use of telehealth visits (43% sites), the use of laboratories at non-study facilities ( 27%), and alterations to the number of required visits (25%).

Other mitigation strategies included use of mail-order medications, (24%), using radiology services at a non-study site (20%), and altering the trial schedules (19%).

The most effective mitigation strategies were felt to be those that allowed flexibility with respect to location. These measures included use of remote monitoring, remote diagnostics, telehealth visits, and modified symptom monitoring.

Effective strategies that increased flexibility in time were delayed visits, delayed assessments, and changes to the Institutional Review Board.

The study was funded by the IASLC, which received industry support to conduct the project. Dr. Smeltzer reported no relevant financial relationships. Dr. Garassino has relationships with AstraZeneca, BMS, Boehringer Ingelheim, Celgene, Daiichi Sankyo, Eli Lilly, Ignyta, Incyte, MedImmune, Mirati, MSD International, Novartis, Pfizer, Regeneron, Roche, Takeda, and Seattle Genetics.

These were the findings from a survey sent to 173 sites of clinical trials in 45 countries around the world. The findings were presented recently at the World Conference on Lung Cancer (WCLC) 2021. The meeting and the survey were organized by the International Association for the Study of Lung Cancer (IASLC).

Responses to the survey revealed that enrollment into lung cancer trials fell by 43% during the early months of the pandemic. Patients stopped attending clinics, and some trials were suspended.

Patients were less willing to visit clinical trial sites, and lockdown restrictions made travel difficult.

Organizers of clinical trials responded by implementing mitigation strategies, such as changing monitoring requirements, increasing use of telehealth, and using local non-study facilities for laboratory and radiology services.

These measures led to an increase in trial enrollment toward the end of 2020, the survey results show.

“The COVID-19 pandemic created many challenges [that led to] reductions in lung cancer clinical trial enrollment,” commented study presenter Matthew P. Smeltzer, PhD, from the Division of Epidemiology, Biostatistics, and Environmental Health, University of Memphis.

The employment of mitigation strategies allowed the removal of “barriers,” and although the pandemic “worsened, trial enrollment began to improve due in part to these strategies,” Dr. Smeltzer said.

Many of these measures were successful and should be maintained, he suggested. Strategies include allowing telehealth visits, performing testing at local laboratories, using local radiology services, mailing experimental agents “where possible,” and allowing flexibility in trial schedules.

This is a “very important” study, commented Marina Garassino, MD, professor of medicine, hematology, and oncology, the University of Chicago Medicine, in her discussion of the abstract.

Irrespective of the pandemic, the regulation and the bureaucracy of clinical trials hinder participation by patients and physicians, she said.

Many of the mitigation strategies highlighted by the survey were similar to recommendations on the conduct of clinical trials published by the American Society of Clinical Oncology during the pandemic. Those recommendations emphasize the use of telehealth and offsite strategies to help with patient monitoring, she noted.

The findings from the survey show that it is possible to conduct more “streamlined and pragmatic trials,” she said.

“More flexible approaches should be approved by the sponsors of clinical trials and global regulatory bodies,” she added.

However, she expressed concern that “with the telehealth visits, we can create some disparities.”

“We have to remember that lung cancer patients are sometimes a very old population, and they are not digitally evolved,” she commented.

Commenting on Twitter, Jennifer C. King, PhD, chief scientific officer at the GO2 Foundation for Lung Cancer, in Washington, D.C., agreed that many of the mitigation strategies identified in the study “are good for patients all of the time, not just during a pandemic.”

Impact on lung cancer clinical trials

The survey, which included 64 questions, was intended to assess the impact of the COVID pandemic on lung cancer clinical trials.

Most of the survey responses came from sites in Europe (37.6%); 21.4% came from Asia, 13.3% came from the United States, and 7.5% came from Canada.

The team found that enrollment into lung cancer trials declined by 43% in 2020 compared to 2019, at an incidence rate ratio of 0.57 (P = .0115).

The largest decreases in enrollment were between April and August 2020, Dr. Smeltzer noted. However, in the last quarter of 2020 (October to December), the differences in enrollment were significantly smaller (P = .0160), despite a marked increase in global COVID-19 cases per month, he added.

The most common challenges faced by clinical trial sites during the pandemic were the following: There were fewer eligible patients (cited by 67% of respondents); compliance protocol was worse (61%); trials were suspended (60%); there was a lack of research staff (48%); and there were institutional closures (39%).

Regarding patient-related challenges, 67% of sites cited less willingness to visit the site. Other challenges included less ability to travel (cited by 60%), reduced access to the trial site (52%), quarantining because of exposure to COVID-19 (40%), and SARS-CoV-2 infection (26%).

Concerns of patients included the following: Fear of SARS-CoV-2 infection, which was cited by 83%; travel restrictions (47%); securing transportation (38%); and access to the laboratory/radiology services (14%).

“Patient willingness to visit the site was a consistent barrier reported across Europe, the U.S., and Canada,” said Dr. Smeltzer, although the effect was smaller in North America, he added.

Regarding mitigation strategies that were employed during the pandemic to combat the challenges and concerns, the team found that the most common measure was the modification of monitoring requirements, used by 44% of sites.

This was followed by the use of telehealth visits (43% sites), the use of laboratories at non-study facilities ( 27%), and alterations to the number of required visits (25%).

Other mitigation strategies included use of mail-order medications, (24%), using radiology services at a non-study site (20%), and altering the trial schedules (19%).

The most effective mitigation strategies were felt to be those that allowed flexibility with respect to location. These measures included use of remote monitoring, remote diagnostics, telehealth visits, and modified symptom monitoring.

Effective strategies that increased flexibility in time were delayed visits, delayed assessments, and changes to the Institutional Review Board.

The study was funded by the IASLC, which received industry support to conduct the project. Dr. Smeltzer reported no relevant financial relationships. Dr. Garassino has relationships with AstraZeneca, BMS, Boehringer Ingelheim, Celgene, Daiichi Sankyo, Eli Lilly, Ignyta, Incyte, MedImmune, Mirati, MSD International, Novartis, Pfizer, Regeneron, Roche, Takeda, and Seattle Genetics.
