When officials closed U.S. schools in March to limit the spread of COVID-19, they may have prevented more than 1 million cases over a 26-day period, a new estimate published online July 29 in JAMA suggests.

But school closures also left blind spots in understanding how children and schools affect disease transmission.

“School closures early in pandemic responses thwarted larger-scale investigations of schools as a source of community transmission,” researchers noted in a separate study, published online July 30 in JAMA Pediatrics, that examined levels of viral RNA in children and adults with COVID-19.

“Our analyses suggest children younger than 5 years with mild to moderate COVID-19 have high amounts of SARS-CoV-2 viral RNA in their nasopharynx, compared with older children and adults,” reported Taylor Heald-Sargent, MD, PhD, and colleagues. “Thus, young children can potentially be important drivers of SARS-CoV-2 spread in the general population, as has been demonstrated with respiratory syncytial virus, where children with high viral loads are more likely to transmit.”

Although the study “was not designed to prove that younger children spread COVID-19 as much as adults,” it is a possibility, Dr. Heald-Sargent, a pediatric infectious diseases specialist at Ann and Robert H. Lurie Children’s Hospital and assistant professor of pediatrics at Northwestern University, Chicago, said in a related news release. “We need to take that into account in efforts to reduce transmission as we continue to learn more about this virus.”.

The study included 145 patients with mild or moderate illness who were within 1 week of symptom onset. The researchers used reverse transcriptase–polymerase chain reaction (rt-PCR) on nasopharyngeal swabs collected at inpatient, outpatient, emergency department, or drive-through testing sites to measure SARS-CoV-2 levels. The investigators compared PCR amplification cycle threshold (CT) values for children younger than 5 years (n = 46), children aged 5-17 years (n = 51), and adults aged 18-65 years (n = 48); lower CT values indicate higher amounts of viral nucleic acid.

Median CT values for older children and adults were similar (about 11), whereas the median CT value for young children was significantly lower (6.5). The differences between young children and adults “approximate a 10-fold to 100-fold greater amount of SARS-CoV-2 in the upper respiratory tract of young children,” the researchers wrote.

“Behavioral habits of young children and close quarters in school and day care settings raise concern for SARS-CoV-2 amplification in this population as public health restrictions are eased,” they write.
 

Modeling the impact of school closures

In the JAMA study, Katherine A. Auger, MD, of Cincinnati Children’s Hospital Medical Center, and colleagues examined at the U.S. population level whether closing schools, as all 50 states did in March, was associated with relative decreases in COVID-19 incidence and mortality.

To isolate the effect of school closures, the researchers used an interrupted time series analysis and included other state-level nonpharmaceutical interventions and variables in their regression models.

“Per week, the incidence was estimated to have been 39% of what it would have been had schools remained open,” Dr. Auger and colleagues wrote. “Extrapolating the absolute differences of 423.9 cases and 12.6 deaths per 100,000 to 322.2 million residents nationally suggests that school closure may have been associated with approximately 1.37 million fewer cases of COVID-19 over a 26-day period and 40,600 fewer deaths over a 16-day period; however, these figures do not account for uncertainty in the model assumptions and the resulting estimates.”

Relative reductions in incidence and mortality were largest in states that closed schools when the incidence of COVID-19 was low, the authors found.
 

Decisions with high stakes

In an accompanying editorial, Julie M. Donohue, PhD, and Elizabeth Miller, MD, PhD, both affiliated with the University of Pittsburgh, emphasized that the results are estimates. “School closures were enacted in close proximity ... to other physical distancing measures, such as nonessential business closures and stay-at-home orders, making it difficult to disentangle the potential effect of each intervention.”

Although the findings “suggest a role for school closures in virus mitigation, school and health officials must balance this with academic, health, and economic consequences,” Dr. Donohue and Dr. Miller added. “Given the strong connection between education, income, and life expectancy, school closures could have long-term deleterious consequences for child health, likely reaching into adulthood.” Schools provide “meals and nutrition, health care including behavioral health supports, physical activity, social interaction, supports for students with special education needs and disabilities, and other vital resources for healthy development.”

In a viewpoint article also published in JAMA, authors involved in the creation of a National Academies of Sciences, Engineering, and Medicine reported on the reopening of schools recommend that districts “make every effort to prioritize reopening with an emphasis on providing in-person instruction for students in kindergarten through grade 5 as well as those students with special needs who might be best served by in-person instruction.

“To reopen safely, school districts are encouraged to ensure ventilation and air filtration, clean surfaces frequently, provide facilities for regular handwashing, and provide space for physical distancing,” write Kenne A. Dibner, PhD, of the NASEM in Washington, D.C., and coauthors.

Furthermore, districts “need to consider transparent communication of the reality that while measures can be implemented to lower the risk of transmitting COVID-19 when schools reopen, there is no way to eliminate that risk entirely. It is critical to share both the risks and benefits of different scenarios,” they wrote.

The JAMA modeling study received funding from the Agency for Healthcare Research and Quality and the National Institutes of Health. The NASEM report was funded by the Brady Education Foundation and the Spencer Foundation. The authors disclosed no relevant financial relationships.

By now it is well known that the COVID-19 pandemic has significantly disrupted primary care. Office visits and revenues have precipitously dropped as physicians and patients alike fear in-person visits may increase their risks of contracting the virus. However, telemedicine has emerged as a lifeline of sorts for many practices, enabling them to conduct visits and maintain contact with patients.

Telemedicine is likely to continue to serve as a tool for primary care providers to improve access to convenient, cost-effective, high-quality care after the pandemic. Another benefit of telemedicine is it can help maintain a portion of a practice’s revenue stream for physicians during uncertain times.

Indeed, the nation has seen recent progress toward telemedicine parity, which refers to the concept of reimbursing providers’ telehealth visits at the same rates as similar in-person visits.

A challenge to adopting telemedicine is that it calls for adjusting established workflows for in-person encounters. A practice cannot simply replicate in-person processes to work for telehealth. While both in-person and virtual visits require adherence to HIPAA, for example, how you actually protect patient privacy will call for different measures. Harking back to the early days of EMR implementation, one does not need to like the telemedicine platform or process, but come to terms with the fact that it is a tool that is here to stay to deliver patient care.

Following are a few tips for primary care practices to help mitigate disruption while embracing telemedicine.

Treat your practice like a laboratory

Adoption may vary between practices depending on many factors, including clinicians’ comfort with technology, clinical tolerance and triage rules for nontouch encounters, state regulations, and more. Every provider group should begin experimenting with telemedicine in specific ways that make sense for them.

One physician may practice telemedicine full-time while the rest abstain, or perhaps the practice prefers to offer telemedicine services during specific hours on specific days. Don’t be afraid to start slowly when you’re trying something new – but do get started with telehealth. It will increasingly be a mainstream medium and more patients will come to expect it.

Train the entire team

Many primary care practices do not enjoy the resources of an information technology team, so all team members essentially need to learn the new skill of telemedicine usage, in addition to assisting patients. That can’t happen without staff buy-in, so it is essential that everyone from the office manager to medical assistants have the training they need to make the technology work. Juggling schedules for telehealth and in-office, activating an account through email, starting and joining a telehealth meeting, and preparing a patient for a visit are just a handful of basic tasks your staff should be trained to do to contribute to the successful integration of telehealth.

Educate and encourage patients to use telehealth

While unfamiliarity with technology may represent a roadblock for some patients, others resist telemedicine simply because no one has explained to them why it’s so important and the benefits it can hold for them. Education and communication are critical, including the sometimes painstaking work of slowly walking patients through the process of performing important functions on the telemedicine app. By providing them with some friendly coaching, patients won’t feel lost or abandoned during what for some may be an unfamiliar and frustrating process.

Manage more behavioral health

Different states and health plans incentivize primary practices for integrating behavioral health into their offerings. Rather than dismiss this addition to your own practice as too cumbersome to take on, I would recommend using telehealth to expand behavioral health care services.

If your practice is working toward a team-based, interdisciplinary approach to care delivery, behavioral health is a critical component. While other elements of this “whole person” health care may be better suited for an office visit, the vast majority of behavioral health services can be delivered virtually.

To decide if your patient may benefit from behavioral health care, the primary care provider (PCP) can conduct a screening via telehealth. Once the screening is complete, the PCP can discuss results and refer the patient to a mental health professional – all via telehealth. While patients may be reluctant to receive behavioral health treatment, perhaps because of stigma or inexperience, they may appreciate the telemedicine option as they can remain in the comfort and familiarity of their homes.

Collaborative Care is both an in-person and virtual model that allows PCP practices to offer behavioral health services in a cost effective way by utilizing a psychiatrist as a “consultant” to the practice as opposed to hiring a full-time psychiatrist. All services within the Collaborative Care Model can be offered via telehealth, and all major insurance providers reimburse primary care providers for delivering Collaborative Care.

When PCPs provide behavioral health treatment as an “extension” of the primary care service offerings, the stigma is reduced and more patients are willing to accept the care they need.

Many areas of the country suffer from a lack of access to behavioral health specialists. In rural counties, for example, the nearest therapist may be located over an hour away. By integrating behavioral telehealth services into your practice’s offerings, you can remove geographic and transportation obstacles to care for your patient population.

Doing this can lead to providing more culturally competent care. It’s important that you’re able to offer mental health services to your patients from a professional with a similar ethnic or racial background. Language barriers and cultural differences may limit a provider’s ability to treat a patient, particularly if the patient faces health disparities related to race or ethnicity. If your practice needs to look outside of your community to tap into a more diverse pool of providers to better meet your patients’ needs, telehealth makes it easier to do that.

Adopting telemedicine for consultative patient visits offers primary care a path toward restoring patient volume and hope for a postpandemic future.

A clinician education program significantly reduced overall antibiotic prescribing during pediatric visits for acute respiratory tract infections, according to data from 57 clinicians who participated in an intervention.

In a study published in Pediatrics, Matthew P. Kronman, MD, of the University of Washington, Seattle, and associates randomized 57 clinicians at 19 pediatric practices to a stepped-wedge clinical trial. The study included visits for acute otitis media, bronchitis, pharyngitis, sinusitis, and upper respiratory infections (defined as ARTI visits) for children aged 6 months to less than 11 years, for a total of 72,723 ARTI visits by 29,762 patients. The primary outcome was overall antibiotic prescribing for ARTI visits.

For the intervention, known as the Dialogue Around Respiratory Illness Treatment (DART) quality improvement (QI) program, clinicians received three program modules containing online tutorials and webinars. These professionally-produced modules included a combination of evidence-based communication strategies and antibiotic prescribing, booster video vignettes, and individualized antibiotic prescribing feedback reports over 11 months.

Overall, the probability of antibiotic prescribing for ARTI visits decreased by 7% (adjusted relative risk 0.93) from baseline to a 2- to 8-month postintervention in an adjusted intent-to-treat analysis.

Analysis of secondary outcomes revealed that prescribing any antibiotics for viral ARTI decreased by 40% during the postintervention period compared to baseline (aRR 0.60).

In addition, second-line antibiotic prescribing decreased from baseline by 34% for streptococcal pharyngitis (aRR 0.66), and by 41% for sinusitis (aRR 0.59); however there was no significant change in prescribing for acute otitis media, the researchers said.

The study findings were limited by several factors including the potential for biased results because of the randomization of clinicians from multiple practices and the potential for clinicians to change their prescribing habits after the start of the study, Dr. Kronman and colleagues noted.

In addition, the study did not include complete data on rapid streptococcal antigen testing, which might eliminate some children from the study population, and the relatively short postintervention period “may not represent the true long-term intervention durability may not represent the true long-term intervention durability,” they said.

However, the results support the potential of the DART program. “The 7% reduction in antibiotic prescribing for all ARTIs, if extrapolated to all ambulatory ARTI visits to pediatricians nationally, would represent 1.5 million fewer antibiotic prescriptions for children with ARTI annually,” they wrote.

“Providing online communication training and evidence-based antibiotic prescribing education in combination with individualized antibiotic prescribing feedback reports may help achieve national goals of reducing unnecessary outpatient antibiotic prescribing for children,” Dr. Kronman and associates concluded.

Combining interventions are key to reducing unnecessary antibiotics use in pediatric ambulatory care, Rana F. Hamdy, MD, MPH, of Children’s National Hospital, Washington, , and Sophie E. Katz, MD, of Vanderbilt University, Nashville, Tenn., wrote in an accompanying editorial (Pediatrics. 2020 Aug 3. doi: 10.1542/peds.2020-012922).

The researchers in the current study “seem to recognize that clinicians are adult learners, and they combine interventions to implement these adult learning theory tenets to improve appropriate antibiotic prescribing,” they wrote. The DART intervention combined best practices training, communications training, and individualized antibiotic prescribing feedback reports to improve communication between providers and families “especially when faced with a situation in which a parent or guardian might expect an antibiotic prescription but the provider does not think one is necessary,” Dr. Hamdy and Dr. Katz said.

Overall, the findings suggest that the interventions work best in combination vs. being used alone, although the study did not evaluate the separate contributions of each intervention, the editorialists wrote.

“In the current study, nonengaged physicians had an increase in second-line antibiotic prescribing, whereas the engaged physicians had a decrease in second-line antibiotic prescribing,” they noted. “This suggests that the addition of communications training could mitigate the undesirable effects that may result from solely using feedback reports.”

“Each year, U.S. children are prescribed as many as 10 million unnecessary antibiotic courses for acute respiratory tract infections,” Kristina A. Bryant, MD, of the University of Louisville, Ky., said in an interview. “Some of these prescriptions result in side effects or allergic reactions, and they contribute to growing antibiotic resistance. We need effective interventions to reduce antibiotic prescribing.”

Although the DART modules are free and available online, busy clinicians might struggle to find time to view them consistently, said Dr. Bryant.

“One advantage of the study design was that information was pushed to clinicians along with communication booster videos,” she said. “We know that education and reinforcement over time works better than a one and done approach.

“Study participants also received feedback over time about their prescribing habits, which can be a powerful motivator for change, although not all clinicians may have easy access to these reports,” she noted.

To overcome some of the barriers to using the modules, clinicians who are “interested in improving their prescribing could work with their office managers to develop antibiotic prescribing reports and schedule reminders to review them,” said Dr. Bryant.

“An individual could commit to education and review of his or her own prescribing patterns, but support from one’s partners and shared accountability is likely to be even more effective,” she said. “Sharing data within a practice and exploring differences in prescribing patterns can drive improvement.

“Spaced education and regular feedback about prescribing patterns can improve antibiotic prescribing for pharyngitis and sinusitis, and reduce antibiotic prescriptions for ARTIs,” Dr. Bryant said. The take-home from the study is that it should prompt anyone who prescribes antibiotics for children to ask themselves how they can improve their own prescribing habits.

“In this study, prescribing for viral ARTIs was reduced but not eliminated. We need additional studies to further reduce unnecessary antibiotic use,” Dr. Bryant said.

In addition, areas for future research could include longer-term follow-up. “Study participants were followed for 2 to 8 months after the intervention ended in June 2018. It would be interesting to know about their prescribing practices now, and if the changes observed in the study were durable,” she concluded.

The study was supported by the National Institutes of Health, along with additional infrastructure funding from the American Academy of Pediatrics and the Health Resources and Services Administration of the Department of Health and Human Services. The researchers had no financial conflicts to disclose.

Dr. Hamdy and Dr. Katz had no financial conflicts to disclose, but Dr. Katz disclosed grant support through the Centers for Disease Control and Prevention as a recipient of the Leadership in Epidemiology, Antimicrobial Stewardship, and Public Health fellowship, sponsored by the Society for Healthcare Epidemiology of America, Infectious Diseases Society of America, and Pediatric Infectious Diseases Society.

In a study published in Pediatrics, Matthew P. Kronman, MD, of the University of Washington, Seattle, and associates randomized 57 clinicians at 19 pediatric practices to a stepped-wedge clinical trial. The study included visits for acute otitis media, bronchitis, pharyngitis, sinusitis, and upper respiratory infections (defined as ARTI visits) for children aged 6 months to less than 11 years, for a total of 72,723 ARTI visits by 29,762 patients.

A study of patients with pulmonary hypertension suggests a reconsideration of the accepted benchmark for pulmonary vascular hypertension as a predictor of heart failure may be warranted.

An elevated pulmonary vascular resistance of 3.0 Wood units or greater has been used as a prognostic marker for death and heart failure in pulmonary hypertension subgroups. But a large, multiyear study of a veterans population suggests that shifting that threshold to 2.2 Wood units in patients with right-heart catheterization may be justified.

Bradley A. Maron, MD, of the Veterans Affairs Boston Healthcare System and Brigham and Women’s Hospital and Harvard Medical School, Boston, and colleagues evaluated 40,082 veterans in the VA Clinical Assessment, Reporting and Tracking (CART) program who had right-heart catheterization (RHC) in the VA system from Oct. 1, 2007, to Sept. 30, 2016.

“To our knowledge, these data provide the first evidence-based information on the continuum of clinical risk related to PVR in patients with elevated pulmonary artery pressure,” the researchers wrote. Their report was published online in Lancet Respiratory Medicine (2020 Jul 27. doi: 10.1016/S2213-2600(20)30317-9).

The retrospective cohort study found that all-cause mortality hazard ratio (HR), when adjusted for clinical variables, and mean pulmonary artery pressure (mPAP) increased progressively beginning at around 2.0 Wood units (WU). Clinically significant mortality HR emerged at 2.2 WU, with an adjusted risk 9% greater than a PVR of 2.1 Wood units (P < .0034), which the study considered the upper limit of normal PVR in health adults of a similar age range (61.5 to 73.5 years) as the study cohort. The researchers noted that a PVR of 3.0 WU has been the standard for forecasting outcomes in pulmonary hypertension (PH) (Eur Heart J. 2010;31:2915-57).

“Overall, these results suggest that reconsidering the hemodynamic parameters that define pulmonary hypertension in patients with cardiopulmonary disease is warranted, and they identify a need for early detection strategies to capture this large and vulnerable population,” the researchers wrote.

A subsequent analysis focused on patients with an mPAP of >19 mm HG (n = 32,725) and found that all-cause death when adjusted over a wide range of clinical variables that included PVR of 2.2 WU increased to a 25% HR. “However,” the researchers added, “a median cardiac output of < 4.0 L/min, which has been shown to be independently associated with adverse outcome, was present only when PVR was more than 4.0 Wood units.”

For a PVR of 2.2-3.0 WU, the median cardiac output was 4.87 L/min; for > 3.0 WU, it was 4.13 L/min. Among the patients with PVR > 2.2 WU (n = 15,780), 13.6% (n = 2,147) had an mPAP of 19-24 mm Hg.

In all patients with mPAP > 19 mm HG, pulmonary artery wedge pressure (PAWP) became a determining risk factor, with 15 mm HG the demarcation between low and high PAWP. At PVR of 2.2 WU, low-PAWP patients had a 52% greater adjusted risk of death and high-PAWP a 23% greater risk. At 4.0 WU, those adjusted risks rose dramatically – to 272% and 58%, for the low- and high-PAWP subgroups, respectively (P < .0001).

“Stratification of patients by PAWP had a major effect on outcome estimates in our study, illustrating the limitations of using the same PVR level to define clinical risk between precapillary and postcapillary pulmonary hypertension,” the researchers wrote.

They called for further study into how these findings impact people with PH but lower levels of cardiopulmonary disease than the cohort. “Overall, these findings support reconsidering the combination of hemodynamic variables used to identify patients with pulmonary hypertension,” the researchers stated.

The analyses of the VA CART database makes this “an interesting study,” said G. Hossein Almassi, MD, FCCP, of the Medical College of Wisconsin and Zablocki VA Medical Center in Milwaukee. “Within its limitation as a retrospective cohort study, the findings of a lower PVR and a lower mean PAP of > 19 mm being associated with increased risk of all-cause mortality and HF hospitalization are significant.”

He added: “Time will tell whether this will be an impetus for the clinicians to consider earlier therapeutic interventions in addition to lifestyle modification such as smoking cessation in this group of patients.”

Most children who tested positive for SARS-CoV-2 had no respiratory illness, according to data from a retrospective study of 22 patients at a single center.

To date, children account for less than 5% of COVID-19 cases in the United States, but details of the clinical presentations in children are limited, wrote Rabia Agha, MD, and colleagues of Maimonides Children’s Hospital, Brooklyn, N.Y.

In a study published in Hospital Pediatrics, the researchers reviewed data from 22 children aged 0-18 years who tested positive for SARS-CoV-2 by polymerase chain reaction (PCR) and were admitted to a single hospital over a 4-week period from March 18, 2020, to April 15, 2020.

Overall, 9 patients (41%) presented with a respiratory illness, and 7 (32%) required respiratory support. Of four patients requiring mechanical ventilation, two had underlying pulmonary disease. The other two patients who required intubation were one with cerebral palsy and status epilepticus and one who presented in a state of cardiac arrest.

The study population ranged from 11 days to 18 years of age, but 45% were infants younger than 1 year. None of the children had a travel history that might increase their risk for SARS-CoV-2 infection; 27% had confirmed exposure to the virus.

Most of the children (82%) were hospitalized within 3 days of the onset of symptoms, and no deaths occurred during the study period. The most common symptom was fever without a source in five (23%) otherwise healthy infants aged 11-35 days. All five of these children underwent a sepsis evaluation, received empiric antibiotics, and were discharged home with negative bacterial cultures within 48-72 hours. Another 10 children had fever in combination with other symptoms.

Other presenting symptoms were respiratory (9), fatigue (6), seizures (2), and headache (1).

Most children with respiratory illness were treated with supportive therapy and antibiotics, but three of those on mechanical ventilation also were treated with remdesivir; all three were ultimately extubated.

Neurological abnormalities occurred in two patients: an 11-year-old otherwise healthy boy who presented with fever, headache, confusion, and seizure but ultimately improved without short-term sequelae; and a 12-year-old girl with cerebral palsy who developed new onset seizures and required mechanical ventilation, but ultimately improved to baseline.

Positive PCR results were identified in seven patients (32%) during the second half of the study period who were initially hospitalized for non-COVID related symptoms; four with bacterial infections, two with illnesses of unknown etiology, and one with cardiac arrest. Another two children were completely asymptomatic at the time of admission but then tested positive by PCR; one child had been admitted for routine chemotherapy and the other for social reasons, Dr. Agha and associates said.

The study findings contrast with early data from China in which respiratory illness of varying severity was the major presentation in children with COVID-19, but support a more recent meta-analysis of 551 cases, the researchers noted. The findings also highlight the value of universal testing for children.

“Our initial testing strategy was according to the federal and local guidelines that recommended PCR testing for the symptoms of fever, cough and shortness of breath, or travel to certain countries or close contact with a confirmed case,” Dr. Agha and colleagues said.

“With the implementation of our universal screening strategy of all admitted pediatric patients, we identified 9 (41%) patients with COVID-19 that would have been missed, as they did not meet the then-recommended criteria for testing,” they wrote.

The results suggest the need for broader guidelines to test pediatric patients because children presenting with other illnesses may be positive for SARS-CoV-2 as well, the researchers said.

“Testing of all hospitalized patients will not only identify cases early in the course of their admission process, but will also help prevent inadvertent exposure of other patients and health care workers, assist in cohorting infected patients, and aid in conservation of personal protective equipment,” Dr. Agha and associates concluded.

The current study is important as clinicians continue to learn about how infection with SARS-CoV-2 presents in different populations, Diana Lee, MD, of the Icahn School of Medicine at Mount Sinai, New York, said in an interview.

“Understanding how it can present in the pediatric population is important in identifying children who may have the infection and developing strategies for testing,” she said.

“I was not surprised by the finding that most children did not present with the classic symptoms of COVID-19 in adults based on other published studies and my personal clinical experience taking care of hospitalized children in New York City,” said Dr. Lee. “Studies from the U.S. and other countries have reported that fewer children experience fever, cough, and shortness of breath [compared with] adults, and that most children have a milder clinical course, though there is a small percentage of children who can have severe or critical illness,” she said.

“A multisystem inflammatory syndrome in children associated with COVID-19 has also emerged and appears to be a postinfectious process with a presentation that often differs from classic COVID-19 infection in adults,” she added.

The take-home message for clinicians is the reminder that SARS-CoV-2 infection often presents differently in children than in adults, said Dr. Lee.

“Children who present to the hospital with non-classic COVID-19 symptoms or with other diagnoses may be positive for SARS-CoV-2 on testing. Broadly testing hospitalized children for SARS-CoV-2 and instituting appropriate isolation precautions may help to protect other individuals from being exposed to the virus,” she said.  

“Further research is needed to understand which individuals are contagious and how to accurately distinguish those who are infectious versus those who are not,” said Dr. Lee. “There have been individuals who persistently test positive for SARS-CoV-2 RNA (the genetic material of the virus), but were not found to have virus in their bodies that can replicate and thereby infect others,” she emphasized. “Further study is needed regarding the likelihood of household exposures in children with SARS-CoV-2 infection given that this study was done early in the epidemic in New York City when testing and contact tracing was less established,” she said.

The study received no outside funding. The researchers had no financial conflicts to disclose. Dr. Lee had no financial conflicts to disclose.

Information about COVID has evolved so quickly that it can be difficult for clinicians to feel confident that they are staying current. These summaries include links to our reference article on diagnosis of COVID-19, which is constantly updated to make sure you have the latest information.

Diagnostic testing for COVID-19 is critical. No one disputes that. But what is in dispute is whom to test, when to test, how to test, what to do while waiting for results, and how accurate those results are when you finally get them.

Here are the answers to those questions, based on the current information.

Whom to test. This is the (relatively) easy part. The ideal answer is that everyone should be tested. The Infectious Diseases Society of America issued tier-based recommendations way back in March, and they still apply. First priority continues to be patients who are ill, healthcare workers, and those with known exposure. But to truly figure out the amount of community spread in a given area, we need to test people who do not have a clear indication for testing. That is particularly true as more people return to work and the Centers for Disease Control and Prevention (CDC) has issued guidelines for workplaces to establish testing programs. Universal testing is recommended for some high-risk settings, such as nursing homes.

One key change: CDC no longer recommends testing to determine whether someone with a known infection is still infectious.

When to test. People with any symptoms suggestive of COVID should be tested, ideally as soon as feasible. But given the ongoing shortages of tests, that may not be possible, particularly for those requiring only symptomatic care. Rather, these patients should be treated as probable cases, with appropriate instructions regarding quarantine. Testing of those with known exposures ideally should be done about 5 days after exposure.

How to test. Only viral nucleic acid or antigen tests should be used to diagnose acute illness. CDC does not currently recommend using serologic assays, now broadly available, for diagnosis of acute infection, though they obviously play an important role in understanding the transmission dynamic of the virus in the general population.

Testing strategies vary from state to state and even within communities in a single state. It is recommended that clinicians check with their own local or state health department for specifics on tests available, indications for testing, and processing details. While often forgotten, it is worth emphasizing that no diagnostic tests have been approved by the US Food and Drug Administration (FDA). Rather, they are available under emergency use authorization (EUA), meaning that they have not been fully vetted by the FDA.

In late July, the FDA expanded authorization for real-time reverse transcription–polymerase chain reaction (rRT-PCR) molecular assays, utilizing nasal or nasopharyngeal swabs, to permit testing of all persons, regardless of exposure history or symptoms. The FDA maintains a list of all approved diagnostic tests and corresponding labs. Current evidence suggests that no one test is better than any other — and most clinicians won›t have a choice anyway. Patients will have to get what is available via their health department or insurance plan.

Two point-of-care antigen tests using nasopharyngeal or nasal samples have been issued an EUA. These tests can be used only in settings with a valid CLIA certificate.

Several commercial laboratories have received approval to process diagnostic tests using patients’ self-collected saliva rather than swabs. One lab has now received authorization for in-home testing without any input from a clinician. These testing options can be a boon for patients who have symptoms or exposure and for whatever reason are unable to get to a diagnostic site. These samples are collected at home and mailed to a lab. Note that these tests are not yet widely available.

Waiting for results. If waiting for results meant a day or even a couple of days, the answer to this one would be easier. But if the wait extends to 1 and even sometimes 2 weeks, then the test is not able to meaningfully guide clinical decisions. The latest guidance from the CDC is that individuals with symptoms suggestive of COVID who do not require hospitalization should remain at home in self-quarantine for at least 10 days from symptom onset. Asymptomatic individuals with a known exposure to someone else with COVID, or participation in a high-risk event like an indoor gathering involving more than 10 persons, should self-quarantine either until they receive a negative test result or 14 days after the exposure.

Accuracy of results. A positive rRT-PCR antigen test is highly accurate, indicating presence of SARS-CoV-2 RNA. There appears to be no significant cross-reactivity with other respiratory viruses or even other coronaviruses. A small study conducted in Korea suggests that patients with persistent positive tests who are beyond 10 days from the initial positive test and are now symptom free are no longer infectious.

For patients with a high suspicion of COVID-19, a negative test should not rule out the infection. The number of false-negative results is not well known, though the resultant risk is “substantial.” A number of factors affect the likelihood of a false-negative test, including when the sample was collected relative to the timing of illness and the type of specimen collected; for example, nasopharyngeal swabs are more likely to be accurate vs nasal or throat specimens. Repeat or serial testing increases the sensitivity but may not always be available. Although rRT-PCR is the current criterion standard, more inclusive consensus-based criteria are likely to emerge because of the concern about these false-negative results.

Although rRT-PCR is the current criterion standard, more inclusive consensus-based criteria are likely to emerge because of the concern about these false-negative results.

Evidence for a link between cannabis use and cardiovascular health remains unsupported, and the potential risks outweigh any potential benefits, according to a scientific statement from the American Heart Association.

American Heart Association

The increased legalization of cannabis and cannabis products in the United States has driven medical professionals to evaluate the safety and efficacy of cannabis in relation to health conditions, wrote Robert L. Page II, PharmD, of the University of Colorado, Aurora, and colleagues.

In a statement published in Circulation, the researchers noted that although cannabis has been shown to relieve pain and other symptoms in certain conditions, clinicians in the United States have been limited from studying its health effects because of federal law restrictions. “Cannabis remains a schedule I controlled substance, deeming no accepted medical use, a high potential for abuse, and an unacceptable safety profile,” the researchers wrote.

The statement addresses issues with the use of cannabis by individuals with cardiovascular disease or those at increased risk. Observational studies have shown no cardiovascular benefits associated with cannabis, the writers noted. The most common chemicals in cannabis include THC (tetrahydrocannabinolic acid) and CBD (cannabidiol).

Some research has shown associations between CBD cardiovascular features including lower blood pressure and reduced inflammation, the writers noted. However, THC, the component of cannabis associated with a “high” or intoxication, has been associated with heart rhythm abnormalities. The writers cited data suggesting an increased risk of heart attacks, atrial fibrillation and heart failure, although more research is needed.

The statement outlines common cannabis formulations including plant-based, extracts, crystalline forms, edible products, and tinctures. In addition, the statement notes that synthetic cannabis products are marketed and used in the United States without subject to regulation.

“Over the past 5 years, we have seen a surge in cannabis use, particularly during the COVID-19 pandemic here in Colorado, especially among adolescents and young adults,” Dr. Page said in an interview. Because of the surge, health care practitioners need to familiarize themselves with not only the benefits, but risks associated with cannabis use regardless of the formulation,” he said. As heart disease remains a leading cause of death in the United States, understanding the cardiovascular risks associated with cannabis is crucial at this time.

Dr. Page noted that popular attitudes about cannabis could pose risks to users’ cardiovascular health. “One leading misconception about cannabis is because it is ‘natural’ it must be safe,” Dr. Page said. “As with all medications, cannabis has side effects, some of which can be cardiovascular in nature,” he said. “Significant drug-drug interactions can occur as CBD and THC, both found in cannabis, inhibit CYP3A4, which metabolizes a large number of medications used to treat many cardiovascular conditions,” he noted.

“Unfortunately, much of the published data is observational in nature due to the federal restrictions on cannabis as a schedule I drug,” said Dr. Page. “Nonetheless, safety signals have emerged regarding cannabis use and adverse cardiovascular outcomes, including myocardial infarction, heart failure, and atrial fibrillation. Carefully designed prospective short- and long-term studies regarding cannabis use and cardiovascular safety are needed,” he emphasized.

Areas in particular need of additional research include the cardiovascular effects of cannabis in several vulnerable populations such as adolescents, older adults, pregnant women, transplant recipients, and those with underlying cardiovascular disease, said Dr. Page.

“Nonetheless, based on the safety signals described within this Clinical Science Statement, an open discussion regarding the risks of using cannabis needs to occur between patient and health care providers,” he said. “Furthermore, patients must be transparent regarding their cannabis use with their cardiologist and primary care provider. The cannabis story will continue to evolve and is a rapidly moving/changing target,” he said.

“Whether cannabis use is a definitive risk factor for cardiovascular disease as with tobacco use is still unknown, and both acute and long-term studies are desperately needed to address this issue,” he said.

Dr. Page had no relevant financial conflicts to disclose.

A study has shown a strong link between sleeping disturbances and depression in patients with chronic obstructive pulmonary disease.

Adults with clinically stable COPD who reported sleep problems were significantly more likely to report depression or anxiety, poor self-efficacy, and poor health-related quality of life, compared with those not reporting sleep problems, according to the findings from a study of 245 patients.

Sleep problems are common in patients with COPD and have been associated with poor COPD-related outcomes, wrote Sang Hee Lee, MD, of Wonkwang University Sanbon Hospital, Gunpo-si, South Korea, and colleagues.

“However, there is a lack of research on factors associated with sleep disturbance in patients with COPD,” they wrote.

In a prospective, multicenter, cross-sectional study published in the Clinical Respiratory Journal, the researchers enrolled 245 adults with COPD who completed the COPD and Asthma Impact Scale (CASIS) to determine sleep impairment. The CASIS was developed to measure sleep-related problems associated with respiratory disease, and scored on a scale of 1-100, with higher scores indicating greater sleep impairment. The average CASIS score was 40.9. The average age of the patients was 67 years, and 92% were men.

Patients’ health-related quality of life, anxiety/depression, and self-efficacy were assessed using the St. George’s Respiratory Questionnaire (SGRQ), the 36-item Short-Form Health Survey (SF-36), Hospital Anxiety and Depression Scale (HADS), and the COPD Self-Efficacy Scale (CSES). The average scores on these measures were 36.0 for the SGRQ; 48.1 and 50.6, respectively, for the physical and mental components of the SF-36; 3.8 and 6.4, respectively, for the HADS-A and HADS-D measures of anxiety and depression; and 3.3 on the CSES.

Worse sleep in these patients was associated with worse scores on measures of mood. In a multivariate analysis, higher scores on all four measures of health-related quality of life were significantly associated with higher CASIS scores (P = .006 for SGRQ; P = .037 for SF-36, P < .001 for HADS, and P = .010 for CSES).

Although the CASIS did not allow for measurement of symptom severity and did not include many items related to breathing problems, the test “shows good internal consistency, test-retest reproducibility, and construct validity according to previous studies,” the researchers wrote. “The CASIS may be a good tool for evaluating sleep disturbances in COPD patients, and further study is needed,” they added.

The study findings were limited by several factors including the cross-sectional study design, lack of data on obstructive sleep apnea, and lack of information on specific treatments such as at-home oxygen use or high-dose steroid use, the researchers noted. However, the results were strengthened by the use of a disease-specific sleep measure, and the study is the first known to include self-efficacy in relation to sleep quality in COPD patients, they reported.

The results highlight the association between depression, poor quality of life, and self-efficacy in relation to poor sleep, and suggest that “Sleep quality could be improved by enhancing HRQL and self-efficacy,” the researchers said. “Screening for mood disorder in patients with COPD is also needed,” they concluded.

The study was supported by the Basic Science Research Program of the National Research Foundation of Korea (NRF) funded by the Ministry of Education, Science and Technology. The researchers had no financial conflicts to disclose.

When the pandemic was just emerging from its infancy and we were just beginning to think about social distancing, I was sitting around enjoying an adult beverage and some gluten free (not my choice) snacks with some friends. A retired nurse who had just celebrated her 80th birthday said, “I can’t wait until they’ve developed a vaccine.” A former electrical engineer sitting just short of 2 meters to her left responded, “Don’t save me a place near the front of the line for something that is being developed in a program called Warp Speed.”

How do you feel about the potential SARS-CoV-2 vaccine? Are you going to roll up your sleeve as soon as the vaccine becomes available in your community? What are you going to suggest to your patients, your children? I suspect many of you will answer, “It depends.” What factors will you be considering when you try to decide between what is likely to be several competing SARS-CoV-2 vaccines?

Will it make any difference to you which biochemical-immune-bending strategy is being used to make the vaccine? All of them will probably be the result of a clever sounding but novel technique, all of them with a track record that is measured in months and not years. Will you be swayed by how large the trials were? Or how long the follow-up lasted? How effective must the vaccine be to convince you that it is worth receiving or recommending? Do you have the tools and experience to make a decision like that? I know I don’t. And should you and I even be put in a position to make that decision?

In the past, you and I may have relied on the Centers for Disease Control and Prevention for advice. But given the somewhat murky and stormy relationship between the CDC and the president, the vaccine recommendation may be issued by the White House and not the CDC.

For those of us who were practicing medicine during the Swine Flu fiasco of 1976, the pace and the politics surrounding the development of a SARS-CoV-2 vaccine has a discomforting déjà vu quality about it. The fact that like this year 1976 was an election year that infused the development process with a sense of urgency above and beyond any of the concerns about the pandemic that never happened. Although causality was never proven, there was a surge in Guillain-Barré syndrome cases that had been linked temporally to the vaccine.

Of course, our pandemic is real, and it would be imprudent to wait a year or more to watch for long-term vaccine sequelae. However, I am more than a little concerned that fast tracking the development process may result in unfortunate consequences in the short term that could have been avoided with a more measured approach to trialing the vaccines.

The sad reality is that as a nation we tend to be impatient. We are drawn to quick fixes that come in a vial or a capsule. We are learning that simple measures like mask wearing and social distancing can make a difference in slowing the spread of the virus. It would be tragic to rush a vaccine into production that at best turns out to simply be an expensive alternative to the measures that we know work or at worst injures more of us than it saves.

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.

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.
