Pulmonary artery denervation (PADN) provides persistent and clinically significant hemodynamic improvements in patients with persistent chronic thromboembolic hypertension (CTEPH) after pulmonary endarterectomy (PEA), according to a randomized, sham-controlled trial.

“PADN in patients with CTEPH after PEA was safe and effective,” according to an investigating team led by Alexander Romanov, MD, PhD.

The mean reduction in pulmonary vascular resistance (PVR) was 258 dyn/sec per cm^–5 for those randomized to PADN versus 149 dyn/sec per cm^–5 (P = .001) for those randomized to the sham procedure, according to the newly published findings.

For the 6-minute walk test (6MWT), the mean distance was 470 m for the experimental group versus 399 m (P = .03) for the controls.

Several secondary endpoints measuring hemodynamics also favored PADN relative to the sham procedure at 12 months. This included the relative increase in tricuspid annular systolic excursion (P = .03) and the increase in the right ventricular fraction area (P < .001).

A total of 50 patients with residual CTEPH for at least 6 months after PEA despite medical therapy were enrolled and randomized. Entry criteria included a mean pulmonary artery pressure (PAP) of 25 mm Hg or greater or PVR greater than 400 dyn/sec per cm^–5 on right heart catheterization. Patients with comorbidities associated with a life expectancy of less than 1 year were excluded.

Those randomized to the sham group were treated with riociguat over the course of follow-up. This therapy was not offered to patients in the PADN group, but all patients were blinded to the procedure and told that riociguat might or might not be administered.

Following the procedure, participating clinicians, who were also blinded to the procedure, were instructed to provide standard therapies for heart failure, such beta-blockers, diuretics, or digoxin, as needed. All patients were placed on an oral anticoagulant.

At 12 months the mean PAP (26 vs. 35 mm Hg; P < .001) and the mean systolic PAP (46 vs. 54 mm Hg; P = .01) were significantly lower in the PADN group versus those who underwent a sham procedure.

About 52% of the PADN group versus 12% of the sham group were classified as responders by the definition of a PVR reduction of at least 150 dyn/sec per cm^–5 and 6MWT improvement of at least 20%, compared with baseline, reported Dr. Romanov, of the E. Meshalkin National Medical Research Center, ministry of health, Novosibirsk, Russia, and coinvestigators.

Of the three deaths caused by heart failure over the course of follow-up, two occurred in the sham group. Of the eight hospitalizations for heart failure, seven (29% of the sham group) occurred among controls versus one in those treated with PADN (4% of this group; P = .049).

There was one groin hematoma at the puncture site in each group. Both resolved without any consequences prior to hospital discharge. There were no other significant procedure-related complications in either group.

Larger multicenter trials are needed to confirm these findings, according to both the trial investigators and Marius M. Hoeper, MD, who is charge of the pulmonary hypertension program at the Hannover (Germany) Medical School.

In an editorial that accompanied publication of these findings, Dr. Hoeper identified the small sample size of this study as one of its limitations, but he said the results are consistent with several other small studies associating pulmonary artery denervation with benefit in pulmonary hypertension.

“It appears as if we are currently witnessing the emergence of a new treatment option for various forms of pulmonary hypertension,” Dr. Hoeper wrote. In his critique of the study, he suggested that it would have been “more informative” if both groups were on background riociguat, but the data from this and other studies so far indicates that ablation to achieve denervation “is safe and feasible.”

The PADN technique used in this study might be relevant to the results. Dr. Hoeper noted that the investigators employed catheter tip–based electroanatomic mapping with a novel remote navigation system with three-dimensional imaging of the right ventricle and central pulmonary arteries.

“Apparently, this approach minimizes radiation exposure and provides precise location of ablation sites,” Dr. Hoeper observed. However, he called for direct comparisons of this tool to the guidance systems used in other studies.

In an interview, Dr. Hoeper acknowledged that it is not yet clear that a large-scale trial of pulmonary artery denervation for the indication evaluated in this study is coming. He noted several strategies in CTEPH are widely used without trials confirming a reduction in clinical events.

“Balloon pulmonary angioplasty for CTEPH has become an established treatment around the world without any randomized, controlled trial and without demonstration of improved outcomes. A couple of well-conducted observational trials might be sufficient to convince physicians to introduce PADN as well,” he said. If such studies associated PADN with “improvements in hemodynamics, exercise capacity, and patient-reported outcomes, it might be sufficient.”

Currently, Dr. Hoeper is most concerned about obtaining further evidence of safety, which he characterized as a “major issue.”

If a multicenter trial is conducted “the primary endpoint should be focused on clinical events,” according to Dr. Romanov, who was asked to comment on the next steps in validating PADN for the treatment of CTEPH-associated pulmonary hypertension persisting after endarterectomy.

“The mortality rate during 1-year long-term follow-up is not so high, but heart failure progression is a problem. So in my view, the primary endpoint should be a composite of death and heart failure hospitalization,” he said. He called for follow-up duration of 2-3 years.

Jonathan Steinberg, MD, director of cardiac clinical trials and education, Summit Medical Group, Montclair, N.J., also called a trial with hard endpoints, such as death, the ideal.

In the meantime, hemodynamic and functional measures “are still quite valuable and move the ball forward for this intervention,” he said in an interview. Senior author of this trial and principle investigator of the recent ERADICATE-AF trial, which evaluated renal denervation in preventing recurrence of atrial fibrillation (JAMA. 2020;323:248-55), Dr. Steinberg predicted, “I do indeed suspect we will see trials that are more accomplishable [than a large-scale, randomized, controlled trial] in the not too distant future.”

Dr. Romanov received funding from Biosense Webster. Dr. Hoeper has received fees for lectures and/or consultations from Acceleron, Actelion, Bayer, Janssen, Merck Sharp & Dohme, and Pfizer.

A substantial decrease in hospital admissions for acute MI was accompanied by a rise in mortality, particularly for ST-segment elevation MI (STEMI), following the onset of the COVID-19 pandemic, according to a cross-sectional retrospective study.

Although it can’t be confirmed from these results that the observed increase in in-hospital acute MI (AMI) mortality are related to delays in seeking treatment, this is a reasonable working hypothesis until more is known, commented Harlan Krumholz, MD, who was not involved in the study.

The analysis, derived from data collected at 49 centers in a hospital system spread across six states, supports previous reports that patients with AMI were avoiding hospitalization, according to the investigators, who were led by Tyler J. Gluckman, MD, medical director of the Center for Cardiovascular Analytics, Providence Heart Institute, Portland, Ore.

When compared with a nearly 14-month period that preceded the COVID-19 pandemic, the rate of AMI-associated hospitalization fell by 19 cases per week (95% confidence interval, –29.0 to –9.0 cases) in the early COVID-19 period, which was defined by the investigators as spanning from Feb. 23, 2020 to March 28, 2020.

The case rate per week then increased by 10.5 (95% CI, 4.6-16.5 cases) in a subsequent 8-week period spanning between March 29, 2020, and May 16, 2020. Although a substantial increase from the early COVID-19 period, the case rate remained below the baseline established before COVID-19.

The analysis looked at 15,244 AMI hospitalizations among 14,724 patients treated in the Providence St. Joseph Hospital System, which has facilities in Alaska, California, Montana, Oregon, Texas, and Washington. The 1,915 AMI cases captured from Feb. 23, 2020, represented 13% of the total.
 

Differences in mortality, patients, treatment

In the early period, the ratio of observed-to-expected (O/E) mortality relative to the pre–COVID-19 baseline increased by 27% (odds ratio, 1.27; 95% CI, 1.07-1.48). When STEMI was analyzed separately, the O/E mortality was nearly double that of the baseline period (OR, 1.96; 95% CI, 1.22-2.70). In the latter post–COVID-19 period of observation, the overall increase in AMI-associated mortality on the basis of an O/E ratio was no longer significant relative to the baseline period (OR, 1.23; 95% CI, 0.98-1.47). However, the relative increase in STEMI-associated mortality on an O/E basis was even greater (OR, 2.40; 95% CI, 1.65-3.16) in the second COVID-19 period analyzed. Even after risk adjustment, the OR for STEMI mortality remained significantly elevated relative to baseline (1.52; 95% CI, 1.02-2.26).

The differences in AMI patients treated before the onset of the COVID-19 pandemic and those treated afterwards might be relevant, according to the investigators. Specifically, patients hospitalized after Feb. 23, 2020 were 1-3 years younger (P < .001) depending on type of AMI, and more likely to be Asian (P = .01).

The length of stay was 6 hours shorter in the early COVID-19 period and 7 hours shorter in the latter period relative to baseline, but an analysis of treatment approaches to non-STEMI and STEMI during the COVID-19 pandemic were not found to be significantly different from baseline.

Prior to the COVID-19 pandemic, 79% of STEMI patients and 77% of non-STEMI patients were discharged home, which was significantly lower than in the early COVID-19 period, when 83% (P = .02) of STEMI and 81% (P = .006) of non-STEMI patients were discharged home. In the latter period, discharge to home care was also significantly higher than in the baseline period.
 

More than fear of COVID-19?

One theory to account for the reduction in AMI hospitalizations and the increase in AMI-related mortality is the possibility that patients were slow to seek care at acute care hospitals because of concern about COVID-19 infection, according to Dr. Gluckman and coinvestigators.

“Given the time-sensitive nature of STEMI, any delay by patients, emergency medical services, the emergency department, or cardiac catheterization laboratory may have played a role,” they suggested.

In an interview, Dr. Gluckman said that further effort to identify the reasons for the increased AMI-related mortality is planned. Pulling data from the electronic medical records of the patients included in this retrospective analysis might be a “challenge,” but Dr. Gluckman reported that he and his coinvestigators plan to look at a different set of registry data that might provide information on sources of delay, particularly in the STEMI population.

“This includes looking at a number of time factors, such as symptom onset to first medical contact, first medical contact to device, and door-in-door-out times,” Dr. Gluckman said. The goal is to “better understand if delays [in treatment] occurred during the pandemic and, if so, how they may have contributed to increases in risk adjusted mortality.”

Dr. Krumholz, director of the Yale Center for Outcomes Research and Evaluation, New Haven, Conn., called this study a “useful” confirmation of changes in AMI-related care with the onset of the COVID-19 pandemic. As reported anecdotally, the study “indicates marked decreases in hospitalizations of patients with AMI even in areas that were not experiencing big outbreaks but did have some restrictions to limit spread,” he noted.

More data gathered by other centers might provide information about what it all means.

“There remain so many questions about what happened and what consequences accrued,” Dr. Krumholz observed. “In the meantime, we need to continue to send the message that people with symptoms that suggest a heart attack need to rapidly seek care.”

The investigators reported having no financial conflicts of interest.

When STEMI was analyzed separately, the O/E mortality was nearly double that of the baseline period (OR, 1.96; 95% CI, 1.22-2.70). In the latter post–COVID-19 period of observation, the overall increase in AMI-associated mortality on the basis of an O/E ratio was no longer significant relative to the baseline period (OR, 1.23; 95% CI, 0.98-1.47). However, the relative increase in STEMI-associated mortality on an O/E basis was even greater (OR, 2.40; 95% CI, 1.65-3.16) in the second COVID-19 period analyzed. Even after risk adjustment, the OR for STEMI mortality remained significantly elevated relative to baseline (1.52; 95% CI, 1.02-2.26).

The differences in AMI patients treated before the onset of the COVID-19 pandemic and those treated afterwards might be relevant, according to the investigators. Specifically, patients hospitalized after Feb. 23, 2020 were 1-3 years younger (P < .001) depending on type of AMI, and more likely to be Asian (P = .01).

The length of stay was 6 hours shorter in the early COVID-19 period and 7 hours shorter in the latter period relative to baseline, but an analysis of treatment approaches to non-STEMI and STEMI during the COVID-19 pandemic were not found to be significantly different from baseline.

Prior to the COVID-19 pandemic, 79% of STEMI patients and 77% of non-STEMI patients were discharged home, which was significantly lower than in the early COVID-19 period, when 83% (P = .02) of STEMI and 81% (P = .006) of non-STEMI patients were discharged home. In the latter period, discharge to home care was also significantly higher than in the baseline period.
 

More than fear of COVID-19?

One theory to account for the reduction in AMI hospitalizations and the increase in AMI-related mortality is the possibility that patients were slow to seek care at acute care hospitals because of concern about COVID-19 infection, according to Dr. Gluckman and coinvestigators.

“Given the time-sensitive nature of STEMI, any delay by patients, emergency medical services, the emergency department, or cardiac catheterization laboratory may have played a role,” they suggested.

In an interview, Dr. Gluckman said that further effort to identify the reasons for the increased AMI-related mortality is planned. Pulling data from the electronic medical records of the patients included in this retrospective analysis might be a “challenge,” but Dr. Gluckman reported that he and his coinvestigators plan to look at a different set of registry data that might provide information on sources of delay, particularly in the STEMI population.

“This includes looking at a number of time factors, such as symptom onset to first medical contact, first medical contact to device, and door-in-door-out times,” Dr. Gluckman said. The goal is to “better understand if delays [in treatment] occurred during the pandemic and, if so, how they may have contributed to increases in risk adjusted mortality.”

Dr. Krumholz, director of the Yale Center for Outcomes Research and Evaluation, New Haven, Conn., called this study a “useful” confirmation of changes in AMI-related care with the onset of the COVID-19 pandemic. As reported anecdotally, the study “indicates marked decreases in hospitalizations of patients with AMI even in areas that were not experiencing big outbreaks but did have some restrictions to limit spread,” he noted.

More data gathered by other centers might provide information about what it all means.

“There remain so many questions about what happened and what consequences accrued,” Dr. Krumholz observed. “In the meantime, we need to continue to send the message that people with symptoms that suggest a heart attack need to rapidly seek care.”

The investigators reported having no financial conflicts of interest.

A methodical, constructive, goal-oriented rapid repetition of emergency response simulations has emerged as a dominant strategy for pediatric readiness in the hospital setting, according to a detailed description of one such program at the virtual Pediatric Hospital Medicine.

Rather than a single run-through followed by a lengthy debriefing, which has been a traditional approach, short simulations done rapidly and repeatedly until skills are mastered improve skill development, according to Jeanmarie Schied, MD, of the department of pediatrics, University of Chicago Medicine.

Collecting cells from the skin surface with adhesive tape strips is demonstrating a level of accuracy that is rivaling skin biopsies for atopic dermatitis and psoriasis, promising a minimally invasive approach for monitoring these and potentially other dermatologic diseases, according to the latest advances with this approach.

“Tape strips are not going to fully replace biopsies, but we think they will have an important role in diagnosing and monitoring response to therapy by avoiding the potential scarring and pain of biopsy,” reported Emma Guttman-Yassky, MD, PhD, professor of dermatology and director of the laboratory inflammatory skin diseases at the Icahn School of Medicine at Mount Sinai Medical Center, New York.

The concept of using adhesive strips to remove surface skin cells for clinical study has been around for more than 20 years, but there has been recent progress. A newly published study, which compared skin from patients with atopic dermatitis (AD) or psoriasis with that of controls, was characterized as “the most comprehensive tape strip molecular profiling in any inflammatory skin disease to date and the first to fully characterize and compare AD to psoriasis,” wrote Dr. Guttman-Yassky, the senior author, and coauthors.

It also appears to be a leap forward. RNA sequencing detected thousands of differentially expressed genes reflecting immune and barrier biomarkers characteristic of the molecular phenotypes of atopic dermatitis and psoriasis. These were not only found to be consistent with biopsy studies but identified additional unique genes and pathways relevant to their pathological signature.

“In the past, the success rate for transcriptome sequencing even for a more limited panel of proteins was approaching 50% when considering both lesional, nonlesional skin, and healthy skin, but we are now approaching 100% for sample recovery and for analysis of RNA and genes,” Dr. Guttman-Yassky said in an interview.

Tissue samples were obtained with tape strips from lesional and nonlesional skin from 20 patients with AD and 20 patients with psoriasis. Compared with 20 tape strips from controls, they were evaluated with RNA sequencing followed by quantitative real-time polymerase chain reaction of immune and barrier biomarkers.

The sample recovery rate was 96% overall and 95% or better regardless of whether the skin was lesional or nonlesional.

With RNA sequencing of more than 20,000 transcripts, including multiple cellular, immune, and barrier biomarkers, an enormous amount of data was generated, but the key finding is that these diseases are readily distinguished with profiling based on tape strips.

Although numerous biomarkers were shared, “tape strips completely discriminate between atopic dermatitis and psoriasis with a degree of reliability that is comparable to skin biopsy,” Dr. Guttman-Yassky said.

One of the biomarkers, expression of nitric oxide synthase 2/inducible nitric oxide synthase, distinguished AD from psoriasis with 100% accuracy. As previously reported in biopsy studies, other biomarkers collectively associated AD with a profile related to a Th2-type inflammatory response and psoriasis with a Th17-type inflammatory response.

Tape strips also confirmed significant pathology in the nonlesional as well as the lesional skin of patients with AD or psoriasis. This included an increase in Th2-type products, such as interleukin-4 and IL-13, in nonlesional skin of atopic dermatitis and Th17-type products, such as IL-17, in nonlesional skin of psoriasis.

Some biomarkers of AD and psoriasis had an even greater differentiation in tape strips than previously reported from biopsy studies, according to Dr. Guttman-Yassky. In this study, tape strips also captured more differentially expressed genes than previously reported with biopsies.

One potential limitation of tape strips is that the RNA isolation process is time consuming, but this might be less of an issue in routine clinical use if there is a more refined number of biomarkers that are targeted or if technological improvements simplify processing, Dr. Guttman-Yassky pointed out.

To develop clinical utility for tape strips beyond AD and psoriasis, more work is needed to standardize the depth of sampling, which is variable with tape strips, she noted. Depth is relevant to the analysis of gene expression and mRNA activity of each dermatologic disease.

“Tape strips remain a research tool for now, but we do think that this technique can be refined and employed for clinical purposes, including diagnosis and monitoring response to treatment,” she said.

Relative to biopsy, the advantages are not difficult to envision. Dr. Guttman-Yassky, who recently published a study of tape strips for evaluating AD in children emphasized that tape strips are generally painless.

“Patients really do not mind tape strips,” she said. Although she believes that tape strips are providing unique insight into the pathology of inflammatory diseases not necessarily available with biopsy, she emphasized the practical value. Not least, “these could really help when the goal is to evaluate response to therapy over time.”

Another investigator who has conducted studies with tape strips, Maja-Lisa Clausen, MD, PhD, also thinks tape strips are likely to become routine clinical tools.

“Once the basis research, validation, and data are out, I think numerous companies will be ready to develop machines for more quick and easy processing, compared to the more labor intensive process that is used today for research,” explained Dr. Clausen, who is in the department of dermatology, Bispebjerb Hospital, University of Copenhagen.

She considers tape strips particularly promising for children, but she thinks the biomarker profiling made possible by these strips might be leading to personalized treatment programs for dermatologic diseases.

“What we need is further validation; which tape to use, how deep, and the importance of storage, which is a big issue in the clinic,” Dr. Clausen said in an interview.

Dr. Guttman-Yassky has financial relationships with multiple pharmaceutical companies, including those with therapies for psoriasis.

The rapid decline in pediatric hospital visits that came quickly after COVID-19 has emerged as a major public health threat, creating the need for adaptations among those offering hospital-based care, according to an objective look at patient numbers that was presented at the virtual Pediatric Hospital Medicine.

“Pre-COVID, operating margins had already taken a significant decline – and there are lots of different reasons for why this was happening – but a lot of hospitals in the United States were going from seeing about a 5% operating margin to closer to 2% to 3%,” said Magna Dias, MD, medical director, pediatric inpatient services, at Yale New Haven Children’s Hospital, Bridgeport, Conn.

This nearly 50% decline “was already putting pressure on us in the community hospital setting where pediatrics is not necessarily generating a ton of revenue to justify our programs, but post COVID, our operating revenue – and this is a report from May – was down 282%,” Dr. Dias reported.

Dr. Dias said that hundreds of hospitals have furloughed workers in the United States since the pandemic began. Although the job losses are not confined to pediatric care, statistics show that pediatrics is one of the hardest hit specialties.

“Looking specifically at ED [emergency department] visits under age 14, one study showed a 71% to 72% decrease post COVID,” Dr. Dias said. This included a 97% reduction in ED visits for flu and more than an 80% reduction in visits for asthma, otitis media, and nausea or vomiting.

It is not clear when children will return to the hospital in pre-COVID-19 numbers, but it might not be soon if the a second wave of infections follows the first, according to Dr. Dias. She suggested that pediatric hospitalists should be thinking about how to expand their services.

“One thing we are really good at in terms of working in the community hospital is diversification. We are used to working in more than one area and being flexible,” Dr. Dias said. Quoting Charles Darwin, who concluded that adaption to change predicts species survival, Dr. Dias advised pediatric hospitalists to look for new opportunities.

Taking on a broader range of responsibilities will not be a significant leap for many pediatric hospitalists. In a survey conducted several years ago by the American Academy of Pediatrics (AAP), hospital staff pediatricians were associated with activities ranging from work in the neonatal intensive care unit to primary ED coverage, according to Dr. Dias. Now with declining patient volumes on pediatric floors, she foresees an even greater expansion, including the care of young adults.

One organization formed in response to the COVID-19 pandemic, called the Pediatric Overflow Planning Contingency Response Network (POPCoRN) has been taking a lead in guiding the delivery of adult care in a pediatric environment. As a cochair of a community hospital special interest group within POPCoRN, Dr. Dias said she has participated in these discussions.

“At some centers, they have gone from age 18 to 21, some have gone up to age 25, some have gone up to 30 years,” she said.

Many centers are working to leverage telemedicine to reach pediatric patients no longer coming to the hospital, according to Dr. Dias.

“There are a lot of people being very creative in telemedicine,” she said. While it is considered as one way “to keep children at your institution,” Dr. Dias said others are considering how telemedicine might provide new opportunities. For one example, telemedicine might be an opportunity to deliver care in rural hospitals without pediatric services.

In an AAP survey of pediatric hospitalists conducted several years ago, justifying services was listed as the second most important concern right after access to subspecialty support. Due to COVID-19, Dr. Dias expects the order of these concerns to flip. Indeed, she predicted that many pediatric hospitalists are going to need to reassess their programs.

“We have started looking at what are our opportunities for building back revenue as well as how to recession-proof our practices should there be another surge and another decrease in pediatric volume,” Dr. Dias said.

The changes in pediatric care are not confined to the hospital setting. According to Amy H. Porter, MD, assistant professor of pediatrics at the Kaiser Permanente Bernard J. Tyson School of Medicine, Pasadena, Calif., COVID-19 has “changed the way pediatric medicine is being practiced.”

Although she works in outpatient pediatric care, she said that routine care “is way down” in this setting as well. Like Dr. Dias, she has witnessed a major increase in the use of telemedicine to reach pediatric patients, but she is very concerned about the large proportion of children who are missing routine care, including vaccinations.

“We were already seeing outbreaks of whooping cough and measles pre COVID, so we are quite worried that we will see more,” Dr. Porter said.

A reduction in demand for care does not have the same immediate effect on revenue at a large health maintenance organization like Kaiser Permanente, but growing unemployment in the general population will mean fewer HMO members. In turn, this could have an impact on the entire system.

“When membership goes down, then it will have implications for how we can provide services,” Dr. Porter said.

In the meantime, social workers at Kaiser Permanente “are tirelessly working” to help parents losing benefits to obtain medicines for sick children with chronic diseases, according to Dr. Porter. She echoed the comments of Dr. Dias in predicting major changes in pediatric care if the COVID-19 pandemic and its economic consequences persist.

The conference was sponsored by the Society of Hospital Medicine, the American Academy of Pediatrics, and the Academic Pediatric Association.

“One thing we are really good at in terms of working in the community hospital is diversification. We are used to working in more than one area and being flexible,” Dr. Dias said. Quoting Charles Darwin, who concluded that adaption to change predicts species survival, Dr. Dias advised pediatric hospitalists to look for new opportunities.

Taking on a broader range of responsibilities will not be a significant leap for many pediatric hospitalists. In a survey conducted several years ago by the American Academy of Pediatrics (AAP), hospital staff pediatricians were associated with activities ranging from work in the neonatal intensive care unit to primary ED coverage, according to Dr. Dias. Now with declining patient volumes on pediatric floors, she foresees an even greater expansion, including the care of young adults.

One organization formed in response to the COVID-19 pandemic, called the Pediatric Overflow Planning Contingency Response Network (POPCoRN) has been taking a lead in guiding the delivery of adult care in a pediatric environment. As a cochair of a community hospital special interest group within POPCoRN, Dr. Dias said she has participated in these discussions.

“At some centers, they have gone from age 18 to 21, some have gone up to age 25, some have gone up to 30 years,” she said.

Many centers are working to leverage telemedicine to reach pediatric patients no longer coming to the hospital, according to Dr. Dias.

“There are a lot of people being very creative in telemedicine,” she said. While it is considered as one way “to keep children at your institution,” Dr. Dias said others are considering how telemedicine might provide new opportunities. For one example, telemedicine might be an opportunity to deliver care in rural hospitals without pediatric services.

In an AAP survey of pediatric hospitalists conducted several years ago, justifying services was listed as the second most important concern right after access to subspecialty support. Due to COVID-19, Dr. Dias expects the order of these concerns to flip. Indeed, she predicted that many pediatric hospitalists are going to need to reassess their programs.

“We have started looking at what are our opportunities for building back revenue as well as how to recession-proof our practices should there be another surge and another decrease in pediatric volume,” Dr. Dias said.

The changes in pediatric care are not confined to the hospital setting. According to Amy H. Porter, MD, assistant professor of pediatrics at the Kaiser Permanente Bernard J. Tyson School of Medicine, Pasadena, Calif., COVID-19 has “changed the way pediatric medicine is being practiced.”

Although she works in outpatient pediatric care, she said that routine care “is way down” in this setting as well. Like Dr. Dias, she has witnessed a major increase in the use of telemedicine to reach pediatric patients, but she is very concerned about the large proportion of children who are missing routine care, including vaccinations.

“We were already seeing outbreaks of whooping cough and measles pre COVID, so we are quite worried that we will see more,” Dr. Porter said.

A reduction in demand for care does not have the same immediate effect on revenue at a large health maintenance organization like Kaiser Permanente, but growing unemployment in the general population will mean fewer HMO members. In turn, this could have an impact on the entire system.

“When membership goes down, then it will have implications for how we can provide services,” Dr. Porter said.

In the meantime, social workers at Kaiser Permanente “are tirelessly working” to help parents losing benefits to obtain medicines for sick children with chronic diseases, according to Dr. Porter. She echoed the comments of Dr. Dias in predicting major changes in pediatric care if the COVID-19 pandemic and its economic consequences persist.

Parents who refuse one indicated neonatal preventive therapy often refuse others even when the reasons are different, according to an update at the virtual Pediatric Hospital Medicine virtual. This finding indicates the value of preparing policies and strategies to guide parents to appropriate medical decisions in advance.

“Elimination of nonmedical exceptions to vaccinations and intramuscular vitamin K made it into two of the AAP [American Academy of Pediatrics] top 10 public health resolutions, most likely because refusal rates are going up,” reported Ha N. Nguyen, MD, of the division of pediatric hospital medicine at Stanford (Calif.) University.

Importantly, state laws differ. For example, erythromycin ointment is mandated in neonates for prevention of gonococcal ophthalmia neonatorum in many states, including New York, where it can be administered without consent, according to Dr. Nguyen. Conversely, California does not mandate this preventive therapy even though the law does not offer medico-legal protection to providers if it is not given.

“There is a glaring gap in the way the [California] law was written,” said Dr. Nguyen, who used this as an example of why protocols and strategies to reduce risk of parental refusal of neonatal therapies should be informed by, and consistent with, state laws.

Because of the low levels of vitamin K in infants, the rate of bleeding within the first few months of life is nearly 2%, according to figures cited by Dr. Nguyen. It falls to less than 0.001% with administration of intramuscular vitamin K.

Families who refuse intramuscular vitamin K often state that they understand the risks, but data from a survey Dr. Nguyen cited found this is not necessarily true. In this survey, about two-thirds knew that bleeding was the risk, but less than 20% understood bleeding risks included intracranial hemorrhage, and less than 10% were aware that there was potential for a fatal outcome.

“This is a huge piece of the puzzle for counseling,” Dr. Nguyen said. “The discussion with parents should explicitly involve the explanation that the risks include brain bleeds and death.”

Although most infant bleeds attributed to low vitamin K stores are mucocutaneous or gastrointestinal, intracranial hemorrhage does occur, and these outcomes can be devastating. Up to 25% of infants who experience an intracranial hemorrhage die, while 60% of those who survive have some degree of neurodevelopmental impairment, according to Dr. Nguyen.

Oral vitamin K, which requires multiple doses, is not an appropriate substitute for the recommended single injection of the intramuscular formulation. The one study that compared intramuscular and oral vitamin K did not prove equivalence, and no oral vitamin K products have been approved by the Food and Drug Administration, Dr. Nguyen reported.

“We do know confidently that oral vitamin K does often result in poor adherence,” she said,

In a recent review article of parental vitamin K refusal, one of the most significant predictors of refusal of any recommended neonatal preventive treatment was refusal of another. According to data in that article, summarized by Dr. Nguyen, 68% of the parents who declined intramuscular vitamin K also declined erythromycin ointment, and more than 90% declined hepatitis B vaccine.

One of the take-away messages from a review of multisystem inflammatory syndrome in children (MIS-C) is that clinicians treating this condition “need to be comfortable with uncertainty,” Melissa Hazen, MD, said at a synthesis of multiple published case series and personal experience summarized at the virtual Pediatric Hospital Medicine meeting.

She emphasized MIS-C patient care “requires flexibility,” and she advised clinicians managing these patients to open the lines of communication with the many specialists who often are required to deal with complications affecting an array of organ systems.

MIS-C might best be understood as the most serious manifestation of an immune-mediated response to COVID-19 infection that ranges from transient mild symptoms to the life-threatening multiple organ involvement that characterizes this newly recognized threat. Although “most children who encounter this pathogen only develop mild disease,” the spectrum of the disease can move in a subset of patients to a “Kawasaki-like illness” without hemodynamic instability and then to MIS-C “with highly elevated systemic inflammatory markers and multiple organ involvement,” explained Dr. Hazen, an attending physician in the rheumatology program at Boston Children’s Hospital.

A reliable profile of MIS-C is only beginning to emerge from the series of published case series, most of which have only recently reached publication, according to Dr. Hazen. In general, the description of the most common symptoms and their course has been relatively consistent.

In 186 cases of MIS-C collected in a study funded by the Centers for Disease Control and Prevention, 148 (80%) were admitted to intensive care, 90 patients (48%) received vasoactive support, 37 (20%) received mechanical ventilation, and 4 (2%) died.¹ The median age was 8 years (range, 3-13 years) in this study. The case definition was fever for at least 24 hours, laboratory evidence of inflammation, multisystem organ involvement, and evidence of COVID-19 infection. In this cohort of 186 children, 92% had gastrointestinal, 80% had cardiovascular, 76% had hematologic, and 70% had respiratory system involvement.

In a different series of 95 cases collected in New York State, 79 (80%) were admitted to intensive care, 61 (62%) received vasoactive support, 10 (10%) received mechanical ventilation, 4 (4%) received extracorporeal membrane oxygenation (ECMO), and 2 (2%) died. ² Thirty-one percent patients were aged 0-5 years, 42% were 6-12 years, and 26% were 13-20 years of age. In that series, for which the case definition was elevation of two or more inflammatory markers, virologic evidence of COVID-19 infection, 80% had gastrointestinal system involvement, and 53% had evidence of myocarditis.

In both of these series, as well as others published and unpublished, the peak in MIS-C cases has occurred about 3 to 4 weeks after peak COVID-19 activity, according to Diana Lee, MD, a pediatrician at Icahn School of Medicine at Mount Sinai, New York. This pattern, reported by others, was observed in New York State, where 230 cases of MIS-C were collected from the beginning of May until the end of June, which reflected this 3- to 4-week delay in peak incidence.

“This does seem to be a rare syndrome since this [group of] 230 cases is amongst the entire population of children in New York State. So, yes, we should be keeping this in mind in our differential, but we should not forget all the other reasons that children can have a fever,” she said.

Both Dr. Hazen and Dr. Lee cautioned that MIS-C, despite a general consistency among published studies, remains a moving target in regard to how it is being characterized. In a 2-day period in May, the CDC, the World Health Organization, and New York State all issued descriptions of MIS-C, employing compatible but slightly different terminology and diagnostic criteria. Many questions regarding optimal methods of diagnosis, treatment, and follow-up remain unanswered.

Questions regarding the risk to the cardiovascular system, one of the organs most commonly affected in MIS-C, are among the most urgent. It is not now clear how best to monitor cardiovascular involvement, how to intervene, and how to follow patients in the postinfection period, according to Kevin G. Friedman, MD, a pediatrician at Harvard Medical School, Boston, and an attending physician in the department of cardiology at Boston Children’s Hospital.

“The most frequent complication we have seen is ventricular dysfunction, which occurs in about half of these patients,” he reported. “Usually it is in the mild to moderate range, but occasionally patients have an ejection fraction of less than 40%.”

Coronary abnormalities, typically in the form of dilations or small aneurysms, occur in 10%-20% of children with MIS-C, according to Dr. Friedman. Giant aneurysms have been reported.

“Some of these findings can progress including in both the acute phase and, particularly for the coronary aneurysms, in the subacute phase. We recommend echocardiograms and EKGs at diagnosis and at 1-2 weeks to recheck coronary size or sooner if there are clinical indications,” Dr. Friedman advised.

Protocols like these are constantly under review as more information becomes available. There are as yet no guidelines, and practice differs across institutions, according to the investigators summarizing this information.

None of the speakers had any relevant financial disclosures.

Since the early 2000s, approximately half of medical students in the United States – and in many years, more than half – have been women, but the proportion of women occupying leadership roles in medicine remains low, according to an update provided at the virtual Pediatric Hospital Medicine.

In pediatrics, a specialty in which approximately 70% of physicians are now women, there has been progress, but still less than 30% of pediatric department chairs are female, said Vincent Chiang, MD, chief medical officer of Boston Children’s Hospital, during a presentation at the virtual meeting sponsored by the Society of Hospital Medicine, the American Academy of Pediatrics, and the Academic Pediatric Association.

Citing published data and a survey he personally conducted of the top children’s hospitals identified by the U.S. News and World Report, Dr. Chiang said a minority of division chiefs, chief medical officers, chief financial officers, and other leaders are female. At his institution, only 2 of 16 division chiefs are female.

“No matter how you slice it, women are underrepresented in leadership positions,” he noted.

The problem is certainly not confined to medicine. Dr. Chiang cited data showing that women and men have reached “near parity” in workforce participation in the United States even though the 20% earnings gap has changed little over time.

According to 2020 data from the World Economic Forum, the United States ranked 51 for the gender gap calculated on the basis of economic, political, educational, and health attainment. Even if this places the United States in the top third of the rankings, it is far behind Iceland and the Scandinavian countries that lead the list.

Efforts to reduce structural biases are part of the fix, but Dr. Chiang cautioned that fundamental changes might never occur if the plan is to wait for an approach based on meritocracy. He said that existing structural biases are “slanted away from women,” who are not necessarily granted the opportunities that are readily available to men.

“A meritocracy only works if the initial playing field was level. Otherwise, it just perpetuates the inequalities,” he said.

The problem is not a shortage of women with the skills to lead. In a study by Zenger/Folkman, a consulting company that works on leadership skill development, women performed better than men in 16 of 18 leadership categories, according to Dr. Chiang.

“There is certainly no shortage of capable women,” he noted.

Of the many issues, Dr. Chiang highlighted two. The first is the challenge of placing women on leadership pathways. This is likely to require proactive strategies, such as fast-track advancement programs that guide female candidates toward leadership roles.

The second is more nuanced. According to Dr. Chiang, women who want to assume a leadership role should think more actively about how and who is making decisions at their institution so they can position themselves appropriately. This is nuanced because “there is a certain amount of gamesmanship,” he said. The rise to leadership “has never been a pure meritocracy.”

Importantly, many of the key decisions in any institution involve money, according to Dr. Chiang. As a result, he advised those seeking leadership roles to join audit committees or otherwise take on responsibility for profit-and-loss management. Even in a nonprofit institution, “you need to make the numbers work,” he said, citing the common catchphrase: “No margin, no mission.”

However, Dr. Chiang acknowledged the many obstacles that prevent women from working their way into positions of leadership. For example, networking is important, but women are not necessarily attracted or invited to some of the social engagements, such as golf outings, where strong relationships are created.

In a survey of 100,000 people working at Fortune 500 companies, “82% of women say they feel excluded at work and much of that comes from that informal networking,” Dr. Chiang said. “Whereas 92% of men think they are not excluding women in their daily work.”

There is no single solution, but Dr. Chiang believes that concrete structural changes are needed. Female doctors remain grossly underrepresented in leadership roles even as they now represent more than half of the workforce for many specialties. Based on the need for proactive approaches outlined by Dr. Chiang, it appears unlikely that gender inequality will ever resolve itself.

Lisa S. Rotenstein, MD, who has written on fixing the gender imbalance in health care, including for the Harvard Business Review, said she agreed during an interview that structural changes are critical.

“In order to address current disparities, leaders should be thinking about how to remove both the formal and informal obstacles that prevent women and minorities from getting into the rooms where these decisions are being made,” said Dr. Rotenstein, who is an instructor in medicine at Brigham and Women’s Hospital, Harvard Medical School in Boston.

“This will need to involve sponsorship that gets women invited to the right committees or in positions with responsibility for profit-and-loss management,” she added.

Dr. Rotenstein spoke about improving “access to the pipeline” that leads to leadership roles. The ways in which women are excluded from opportunities is often subtle and difficult to penetrate without fundamental changes, she explained.

“Institutions need to understand the processes that lead to leadership roles and make the changes that allow women and minorities to participate,” she said. It is not enough to recognize the problem, according to Dr. Rotenstein.

Like Dr. Chiang, she noted that changes are needed in the methods that move underrepresented groups into leadership roles.

Dr. Chiang reported no potential conflicts of interest relevant to this study.

Since the early 2000s, approximately half of medical students in the United States – and in many years, more than half – have been women, but the proportion of women occupying leadership roles in medicine remains low, according to an update provided at the virtual Pediatric Hospital Medicine.

In pediatrics, a specialty in which approximately 70% of physicians are now women, there has been progress, but still less than 30% of pediatric department chairs are female, said Vincent Chiang, MD, chief medical officer of Boston Children’s Hospital, during a presentation at the virtual meeting sponsored by the Society of Hospital Medicine, the American Academy of Pediatrics, and the Academic Pediatric Association.

Citing published data and a survey he personally conducted of the top children’s hospitals identified by the U.S. News and World Report, Dr. Chiang said a minority of division chiefs, chief medical officers, chief financial officers, and other leaders are female. At his institution, only 2 of 16 division chiefs are female.

“No matter how you slice it, women are underrepresented in leadership positions,” he noted.

The problem is certainly not confined to medicine. Dr. Chiang cited data showing that women and men have reached “near parity” in workforce participation in the United States even though the 20% earnings gap has changed little over time.

According to 2020 data from the World Economic Forum, the United States ranked 51 for the gender gap calculated on the basis of economic, political, educational, and health attainment. Even if this places the United States in the top third of the rankings, it is far behind Iceland and the Scandinavian countries that lead the list.

Efforts to reduce structural biases are part of the fix, but Dr. Chiang cautioned that fundamental changes might never occur if the plan is to wait for an approach based on meritocracy. He said that existing structural biases are “slanted away from women,” who are not necessarily granted the opportunities that are readily available to men.

“A meritocracy only works if the initial playing field was level. Otherwise, it just perpetuates the inequalities,” he said.

The problem is not a shortage of women with the skills to lead. In a study by Zenger/Folkman, a consulting company that works on leadership skill development, women performed better than men in 16 of 18 leadership categories, according to Dr. Chiang.

“There is certainly no shortage of capable women,” he noted.

Of the many issues, Dr. Chiang highlighted two. The first is the challenge of placing women on leadership pathways. This is likely to require proactive strategies, such as fast-track advancement programs that guide female candidates toward leadership roles.

The second is more nuanced. According to Dr. Chiang, women who want to assume a leadership role should think more actively about how and who is making decisions at their institution so they can position themselves appropriately. This is nuanced because “there is a certain amount of gamesmanship,” he said. The rise to leadership “has never been a pure meritocracy.”

Importantly, many of the key decisions in any institution involve money, according to Dr. Chiang. As a result, he advised those seeking leadership roles to join audit committees or otherwise take on responsibility for profit-and-loss management. Even in a nonprofit institution, “you need to make the numbers work,” he said, citing the common catchphrase: “No margin, no mission.”

However, Dr. Chiang acknowledged the many obstacles that prevent women from working their way into positions of leadership. For example, networking is important, but women are not necessarily attracted or invited to some of the social engagements, such as golf outings, where strong relationships are created.

In a survey of 100,000 people working at Fortune 500 companies, “82% of women say they feel excluded at work and much of that comes from that informal networking,” Dr. Chiang said. “Whereas 92% of men think they are not excluding women in their daily work.”

There is no single solution, but Dr. Chiang believes that concrete structural changes are needed. Female doctors remain grossly underrepresented in leadership roles even as they now represent more than half of the workforce for many specialties. Based on the need for proactive approaches outlined by Dr. Chiang, it appears unlikely that gender inequality will ever resolve itself.

Lisa S. Rotenstein, MD, who has written on fixing the gender imbalance in health care, including for the Harvard Business Review, said she agreed during an interview that structural changes are critical.

“In order to address current disparities, leaders should be thinking about how to remove both the formal and informal obstacles that prevent women and minorities from getting into the rooms where these decisions are being made,” said Dr. Rotenstein, who is an instructor in medicine at Brigham and Women’s Hospital, Harvard Medical School in Boston.

“This will need to involve sponsorship that gets women invited to the right committees or in positions with responsibility for profit-and-loss management,” she added.

Dr. Rotenstein spoke about improving “access to the pipeline” that leads to leadership roles. The ways in which women are excluded from opportunities is often subtle and difficult to penetrate without fundamental changes, she explained.

“Institutions need to understand the processes that lead to leadership roles and make the changes that allow women and minorities to participate,” she said. It is not enough to recognize the problem, according to Dr. Rotenstein.

In elderly or low-weight patients with acute coronary syndrome (ACS), a reduced dose of prasugrel relative to a full-dose of ticagrelor is associated with lower numerical rates of ischemic events and bleeding events, according to a prespecified substudy of the ISAR-REACT 5 trial.

“The present study provides the strongest support for reduced-dose prasugrel as the standard for elderly and low-weight patients with ACS undergoing an invasive treatment strategy,” according to the senior author, Adnan Kastrati, MD, professor of cardiology and head of the Catheterization Laboratory at Deutsches Herzzentrum, Technical University of Munich.

The main results of ISAR-REACT 5, an open-label, head-to-head comparison of prasugrel and ticagrelor in patients with ACS, showed that the risk of the composite primary endpoint of death, myocardial infarction, or stroke 1 year after randomization was significantly higher for those on ticagrelor than prasugrel (hazard ratio, 1.39; P = .006). The bleeding risk on ticagrelor was also higher but not significantly different (5.4% vs. 4.8%; P = .46) (Schüpke S et al. N Engl J Med. 2019 Oct;381:1524-34).

In this substudy newly published in Annals of Internal Medicine, outcomes were compared in the 1,099 patients who were 75 years or older or weighed less than 60 kg. In this group, unlike those younger or weighing more, patients were randomized to receive a reduced maintenance dose of 5 mg of once-daily prasugrel (rather than 10 mg) or full dose ticagrelor (90 mg twice daily).

At 1 year, the low-dose prasugrel strategy relative to ticagrelor was associated with a lower rate of events (12.7% vs. 14.6%) and a lower rate of bleeding (8.1% vs. 10.6%), defined as Bleeding Academic Research Consortium (BARC) type 3-5 events.

Neither the 18% reduction for the efficacy endpoint (HR, 0.82; 95% CI 0.60-1.14) nor the 28% reduction in the bleeding endpoint (HR, 0.72; 95% CI 0.46-1.12) reached significance, but Dr. Kastrati reported that there was a significant “treatment effect-by-study-group interaction” for BARC 1-5 bleeding (P = .004) favoring prasugrel. This supports low-dose prasugrel as a strategy to prevent the excess bleeding risk previously observed with the standard 10-mg dose of prasugrel.

In other words, a reduced dose of prasugrel, compared with the standard dose of ticagrelor, in low-weight and elderly patients “is associated with maintained anti-ischemic efficacy while protecting these patients against the excess risk of bleeding,” he and his coinvestigators concluded.

Low-weight and older patients represented 27% of those enrolled in ISAR-REACT 5. When compared to the study population as a whole, the risk for both ischemic and bleeding events was at least twice as high, the authors of an accompanying editorial observed. They praised this effort to refine the optimal antiplatelet regimen in a very-high-risk ACS population.

“The current analysis suggests that the prasugrel dose reduction regimen for elderly or underweight patients with ACS is effective and safe,” according to the editorial coauthors, David Conen, MD, and P.J. Devereaux, MD, PhD, who are affiliated with the Population Health Research Institute, Hamilton, Ontario.

This substudy was underpowered to show superiority for the efficacy and safety outcomes in elderly and low-weight ACS patients, which makes these results “hypothesis generating,” but the authors believe that they provide the best available evidence for selecting antiplatelet therapy in this challenging subgroup. Although the exclusion of patients at very high risk of bleeding from ISAR-REACT 5 suggest findings might not be relevant to all elderly and low-weight individuals, the investigators believe the data do inform clinical practice.

“Our study is the first head-to-head randomized comparison of the reduced dose of prasugrel against standard dose of ticagrelor in elderly and low-weight patients,” said Dr. Kastrati in an interview. “Specifically designed studies for this subset of patients are very unlikely to be conducted in the future.”

Dr. Kastrati reported no potential conflicts of interest relevant to this study.

ED physicians and hospitalists should consider a diagnosis of e-cigarette associated lung injury (EVALI) across a broad range of nonspecific symptoms, according to a synthesis of current information presented at the virtual Pediatric Hospital Medicine.

Respiratory symptoms, including cough, chest pain, and shortness of breath are common but so are constitutive symptoms, including fever, sore throat, muscle aches, nausea and vomiting, said Yamini Kuchipudi, MD, a staff physician at Cincinnati Children’s Hospital, during the session at the virtual meeting, sponsored by the Society of Hospital Medicine, the American Academy of Pediatrics, and the Academic Pediatric Association.

If EVALI is not considered across this broad array of symptoms, of which respiratory complaints might not be the most prominent at the time of presentation, the diagnosis might be delayed, Dr. Kuchipudi warned during the virtual meeting.

Teenagers and young adults are the most common users of e-cigarettes and vaping devices. In these patients or in any individual suspected of having EVALI, Dr. Kuchipudi recommended posing questions about vaping relatively early in the work-up “in a confidential and nonjudgmental way.”

Eliciting a truthful history will be particularly important, because the risk of EVALI appears to be largely related to vaping with tetrahydrocannabinol (THC)-containing products rather than with nicotine alone. Although the exact cause of EVALI is not yet completely clear, this condition is now strongly associated with additives to the THC, according to Issa Hanna, MD, of the department of pediatrics at the University of Florida, Jacksonville.

“E-liquid contains products like hydrocarbons, vitamin E acetate, and heavy metals that appear to damage the alveolar epithelium by direct cellular inflammation,” Dr. Hanna explained.

These products are not only found in THC processed for vaping but also for dabbing, a related but different form of inhalation that involves vaporization of highly concentrated THC waxes or resins. Dr. Hanna suggested that the decline in reported cases of EVALI, which has followed the peak incidence in September 2019, is likely to be related to a decline in THC additives as well as greater caution among users.

E-cigarettes were introduced in 2007, according to Dr. Hanna, but EVALI was not widely recognized until cases began accruing early in 2019. By June 2019, the growing number of case reports had attracted the attention of the media as well as public health officials, intensifying the effort to isolate the risks and causes.

Consistent with greater use of e-cigarettes and vaping among younger individuals, nearly 80% of the 2,807 patients hospitalized for EVALI in the United States by February of this year occurred in individuals aged less than 35 years, according to data released by the Centers for Disease Control and Prevention. The median age was less than 25 years. Of these hospitalizations, 68 deaths (2.5%) in 29 states and Washington, D.C., were attributed to EVALI.

Because of the nonspecific symptoms and lack of a definitive diagnostic test, EVALI is considered a diagnosis of exclusion, according to Abigail Musial, MD, who is completing a fellowship in hospital medicine at Cincinnati Children’s. She presented a case in which a patient suspected of EVALI went home after symptoms abated on steroids.

“Less than 24 hours later, she returned to the ED with tachypnea and hypoxemia,” Dr. Musial recounted. Although a chest x-ray at the initial evaluation showed lung opacities, a repeat chest x-ray when she returned to the ED showed bilateral worsening of these opacities and persistent elevation of inflammatory markers.

“She was started on steroids and also on antibiotics,” Dr. Musial said. “She was weaned quickly from oxygen once the steroids were started and was discharged on hospital day 3.”

For patients suspected of EVALI, COVID-19 testing should be part of the work-up, according to Dr. Kuchipudi. She also recommended an x-ray or CT scan of the lung as well as an evaluation of inflammatory markers.

Dr. Kuchipudi said that more invasive studies than lung function tests, such as bronchoalveolar lavage or lung biopsy, might be considered when severe symptoms make aggressive diagnostic studies attractive.

Steroids and antibiotics typically lead to control of acute symptoms, but patients should be clinically stable for 24-48 hours prior to hospital discharge, according to Dr. Kuchipudi. Follow-up after discharge should include lung function tests and imaging 2-4 weeks later to confirm resolution of abnormalities.

Dr. Kuchipudi stressed the opportunity that an episode of EVALI provides to induce patients to give up nicotine and vaping entirely. Such strategies, such as a nicotine patch, deserve consideration, but she also cautioned that e-cigarettes for smoking cessation should not be recommended to EVALI patients.

The speakers reported no potential conflicts of interest relevant to this study.

Dr. Hanna suggested that the decline in reported cases of EVALI, which has followed the peak incidence in September 2019, is likely to be related to a decline in THC additives as well as greater caution among users.

E-cigarettes were introduced in 2007, according to Dr. Hanna, but EVALI was not widely recognized until cases began accruing early in 2019. By June 2019, the growing number of case reports had attracted the attention of the media as well as public health officials, intensifying the effort to isolate the risks and causes.

Consistent with greater use of e-cigarettes and vaping among younger individuals, nearly 80% of the 2,807 patients hospitalized for EVALI in the United States by February of this year occurred in individuals aged less than 35 years, according to data released by the Centers for Disease Control and Prevention. The median age was less than 25 years. Of these hospitalizations, 68 deaths (2.5%) in 29 states and Washington, D.C., were attributed to EVALI.

Because of the nonspecific symptoms and lack of a definitive diagnostic test, EVALI is considered a diagnosis of exclusion, according to Abigail Musial, MD, who is completing a fellowship in hospital medicine at Cincinnati Children’s. She presented a case in which a patient suspected of EVALI went home after symptoms abated on steroids.

“Less than 24 hours later, she returned to the ED with tachypnea and hypoxemia,” Dr. Musial recounted. Although a chest x-ray at the initial evaluation showed lung opacities, a repeat chest x-ray when she returned to the ED showed bilateral worsening of these opacities and persistent elevation of inflammatory markers.

“She was started on steroids and also on antibiotics,” Dr. Musial said. “She was weaned quickly from oxygen once the steroids were started and was discharged on hospital day 3.”

For patients suspected of EVALI, COVID-19 testing should be part of the work-up, according to Dr. Kuchipudi. She also recommended an x-ray or CT scan of the lung as well as an evaluation of inflammatory markers.

Dr. Kuchipudi said that more invasive studies than lung function tests, such as bronchoalveolar lavage or lung biopsy, might be considered when severe symptoms make aggressive diagnostic studies attractive.

Steroids and antibiotics typically lead to control of acute symptoms, but patients should be clinically stable for 24-48 hours prior to hospital discharge, according to Dr. Kuchipudi. Follow-up after discharge should include lung function tests and imaging 2-4 weeks later to confirm resolution of abnormalities.

Dr. Kuchipudi stressed the opportunity that an episode of EVALI provides to induce patients to give up nicotine and vaping entirely. Such strategies, such as a nicotine patch, deserve consideration, but she also cautioned that e-cigarettes for smoking cessation should not be recommended to EVALI patients.
