COVID-19 cases in children nearly doubled in just 4 weeks
The cumulative number of new COVID-19 cases among children in the United States jumped by 90% during a recent 4-week period, according to a report that confirms children are not immune to the coronavirus.
“In areas with rapid community spread, it’s likely that more children will also be infected, and these data show that,” Sally Goza, MD, president of the American Academy of Pediatrics, said in a written statement. “I urge people to wear cloth face coverings and be diligent in social distancing and hand-washing. It is up to us to make the difference, community by community.”
The joint report from the AAP and the Children’s Hospital Association draws on data from state and local health departments in 49 states, New York City, the District of Columbia, Puerto Rico, and Guam.
The cumulative number of COVID-19 cases in children as of Aug. 6, 2020, was 380,174, and that number is 90% higher – an increase of 179,990 cases – than the total on July 9, just 4 weeks earlier, the two organizations said in the report.
and 27 states out of 47 with available data now report that over 10% of their cases were children, with Wyoming the highest at 16.5% and New Jersey the lowest at 2.9%, the report data show.
Alabama has a higher percentage of 22.5%, but the state has been reporting cases in individuals aged 0-24 years as child cases since May 7. The report’s findings are somewhat limited by differences in reporting among the states and by “gaps in the data they are reporting [that affect] how the data can be interpreted,” the AAP said in its statement.
The cumulative number of cases per 100,000 children has risen from 13.3 in mid-April, when the total number was 9,259 cases, to 500.7 per 100,000 as of Aug. 6, and there are now 21 states, along with the District of Columbia, reporting a rate of over 500 cases per 100,000 children. Arizona has the highest rate at 1,206.4, followed by South Carolina (1,074.4) and Tennessee (1,050.8), the AAP and the CHA said.
In New York City, the early epicenter of the pandemic, the 390.5 cases per 100,000 children have been reported, and in New Jersey, which joined New York in the initial surge of cases, the number is 269.5. As of Aug. 6, Hawaii had the fewest cases of any state at 91.2 per 100,000, according to the report.
Children continue to represent a very low proportion of COVID-19 deaths, “but as case counts rise across the board, that is likely to impact more children with severe illness as well,” Sean O’Leary, MD, MPH, vice chair of the AAP’s committee on infectious diseases, said in the AAP statement.
It is possible that “some of the increase in numbers of cases in children could be due to more testing. Early in the pandemic, testing only occurred for the sickest individuals. Now that there is more testing capacity … the numbers reflect a broader slice of the population, including children who may have mild or few symptoms,” the AAP suggested.

Antibiotic resistance: Personal responsibility in somewhat short supply
Most primary care physicians agree that antibiotic resistance and inappropriate prescribing are problems in the United States, but they are much less inclined to recognize these issues in their own practices, according to the results of a nationwide survey.
Open Forum Infectious Diseases.
Almost all (94%) of the 1,550 internists, family physicians, and pediatricians who responded to the survey said that antibiotic resistance is a national problem, and nearly that many (91%) agreed that “inappropriate antibiotic prescribing is a problem in outpatient health care settings,” the investigators acknowledged.
Narrowing the focus to their own practices, however, changed some opinions. At that level, only 55% of the respondents said that resistance was a problem for their practices, and just 37% said that there any sort of inappropriate prescribing going on, based on data from the survey, which was conducted from August to October 2018 by Pew and the American Medical Association.
Antibiotic stewardship, defined as activities meant to ensure appropriate prescribing of antibiotics, should include “staff and patient education, clinician-level antibiotic prescribing feedback, and communications training on how to discuss antibiotic prescribing with patients,” Ms. Zetts and associates explained.
The need for such stewardship in health care settings was acknowledged by 72% of respondents, but 53% of those surveyed also said that all they need to do to support such efforts “is to talk with their patients about the value of an antibiotic for their symptoms,” they noted.
The bacteria, it seems, are not the only ones with some resistance. Half of the primary care physicians believe that it would be difficult to fairly and accurately track the appropriate use of antibiotics, and 52% agreed with the statement that “practice-based reporting requirements for antibiotic use would be too onerous,” the researchers pointed out.
“Antibiotic resistance is an impending public health crisis. We are seeing today, as we respond to the COVID-19 pandemic, what our health system looks like with no or limited treatments available to tackle an outbreak. … We must all remain vigilant in combating the spread of antibiotic resistant bacteria and be prudent when prescribing antibiotics,” AMA President Susan R. Bailey, MD, said in a written statement.

Studies gauge role of schools, kids in spread of COVID-19
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.

“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.

Telemedicine in primary care
How to effectively utilize this tool
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.
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.

Guidance covers glycemia in dexamethasone-treated COVID-19 patients
New guidance from the U.K. National Diabetes COVID-19 Response Group addresses glucose management in patients with COVID-19 who are receiving dexamethasone therapy.
Although there are already guidelines that address inpatient management of steroid-induced hyperglycemia, the authors of the new document wrote that this new expert opinion paper was needed “given the ‘triple insult’ of dexamethasone-induced–impaired glucose metabolism, COVID-19–induced insulin resistance, and COVID-19–impaired insulin production.”
RECOVERY trial spurs response
The document, which is the latest in a series from the Association of British Clinical Diabetologists, was published online Aug. 2 in Diabetic Medicine. The group is chaired by Gerry Rayman, MD, consultant physician at the diabetes centre and diabetes research unit, East Suffolk (England) and North East NHS Foundation Trust.
The guidance was developed in response to the recent “breakthrough” Randomised Evaluation of COVID-19 Therapy (RECOVERY) trial, which showed that dexamethasone reduced deaths in patients with COVID-19 on ventilators or receiving oxygen therapy. The advice is not intended for critical care units but can be adapted for that use.
The dose used in RECOVERY – 6 mg daily for 10 days – is 400%-500% greater than the therapeutic glucocorticoid replacement dose. High glucocorticoid doses can exacerbate hyperglycemia in people with established diabetes, unmask undiagnosed diabetes, precipitate hyperglycemia or new-onset diabetes, and can also cause hyperglycemic hyperosmolar state (HHS), the authors explained.
They recommended a target glucose of 6.0-10.0 mmol/L (108-180 mg/dL), although they say up to 12 mmol/L (216 mg/dL) is “acceptable.” They then gave advice on frequency of monitoring for people with and without known diabetes, exclusion of diabetic ketoacidosis and HHS, correction of initial hyperglycemia and maintenance of glycemic control using subcutaneous insulin, and prevention of hypoglycemia at the end of dexamethasone therapy (day 10) with insulin down-titration, discharge, and follow-up.
The detailed insulin guidance covers dose escalation for both insulin-treated and insulin-naive patients. A table suggests increasing correction doses of rapid-acting insulin based on prior total daily dose or weight.
Use of once- or twice-daily NPH insulin is recommended for patients whose glucose has risen above 12 mmol/L, in some cases with the addition of a long-acting analog. A second chart gives dose adjustments for those insulins. Additional guidance addresses patients on insulin pumps.
Guidance useful for U.S. physicians
Francisco Pasquel, MD, assistant professor of medicine in the division of endocrinology at Emory University, Atlanta, said in an interview that he believes the guidance is “acceptable” for worldwide use, and that “it’s coherent and consistent with what we typically do.”
However, Dr. Pasquel, who founded COVID-in-Diabetes, an online repository of published guidance and shared experience – to which this new document has now been added – did take issue with one piece of advice. The guidance says that patients already taking premixed insulin formulations can continue using them while increasing the dose by 20%-40%. Given the risk of hypoglycemia associated with those formulations, Dr. Pasquel said he would switch those patients to NPH during the time that they’re on dexamethasone.
He also noted that the rapid-acting insulin dose range of 2-10 units provided in the first table, for correction of initial hyperglycemia, are more conservative than those used at his hospital, where correction doses of up to 14-16 units are sometimes necessary.
But Dr. Pasquel praised the group’s overall efforts since the pandemic began, noting that “they’re very organized and constantly updating their recommendations. They have a unified system in the [National Health Service], so it’s easier to standardize. They have a unique [electronic health record] which is far superior to what we do from a public health perspective.”
Dr. Rayman reported no relevant financial relationships. Dr. Pasquel reported receiving research funding from Dexcom, Merck, and the National Institutes of Health, and consulting for AstraZeneca, Eli Lilly, Merck, and Boehringer Ingelheim.

Educational intervention curbs use of antibiotics for respiratory infections
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.

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.

Many children with COVID-19 present without classic symptoms
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.
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. 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.

Posaconazole prophylaxis was effective in children with ALL undergoing chemotherapy
Targeted prophylaxis with posaconazole was more effective than fluconazole in children with acute lymphoblastic leukemia who were undergoing induction chemotherapy in order to prevent invasive fungal infection, according to a study by Tian Zhang of Xidian University, Xi’an, China, and colleagues.
The researchers performed a single-center, retrospective cohort study of 155 patients with newly diagnosed acute lymphoblastic leukemia, comparing invasive fungal infections in those who received no prophylaxis (60 patients), posaconazole prophylaxis (70), or fluconazole prophylaxis (55) during induction therapy, according to a report published in the Journal of Microbiology, Immunology and Infection.
Proven and probable invasive fungal infections occurred during the induction phase in 45% in the no-prophylaxis group, in 18% of the posaconazole group and in 72% of the fluconazole group. Posaconazole prophylaxis reduced the odds of invasive fungal infections by greater than 60%, prolonged infection-free survival significantly, and did not increase the risk of hepatotoxicity.
In addition, the researchers found that the combination of age at diagnosis, clinically documented bacterial infection in the first 15 days of induction therapy, and absolute neutrophil count curve enabled significant prediction of the susceptibility to infections after receiving posaconazole prophylaxis.
“In general, these findings may serve as a basis for developing screening protocols to identify children who are at high risk for infection despite posaconazole prophylaxis so that early intervention can be initiated to mitigate fungal infections,” the researchers concluded.
The authors reported that they had no conflicts of interest.

Cutaneous clues linked to COVID-19 coagulation risk
, new evidence suggests.
Researchers at Weill Cornell Medicine NewYork–Presbyterian Medical Center in New York linked livedoid and purpuric skin eruptions to a greater likelihood for occlusive vascular disease associated with SARS-CoV-2 infection in a small case series.
These skin signs could augment coagulation assays in this patient population. “Physicians should consider a hematology consult for potential anticoagulation in patients with these skin presentations and severe COVID-19,” senior author Joanna Harp, MD, said in an interview.
“Physicians should also consider D-dimer, fibrinogen, coagulation studies, and a skin biopsy given that there are other diagnoses on the differential as well.”
The research letter was published online on Aug. 5 in JAMA Dermatology.
The findings build on multiple previous reports of skin manifestations associated with COVID-19, including a study of 375 patients in Spain. Among people with suspected or confirmed SARS-CoV-2 infection, senior author of the Spanish research, Ignacio Garcia-Doval, MD, PhD, also observed livedoid and necrotic skin eruptions more commonly in severe disease.
“I think that this case series [from Harp and colleagues] confirms the findings of our previous paper – that patients with livedoid or necrotic lesions have a worse prognosis, as these are markers of vascular occlusion,” he said in an interview.
Dr. Harp and colleagues reported their observations with four patients aged 40-80 years. Each had severe COVID-19 with acute respiratory distress syndrome and required intubation. Treating clinicians requested a dermatology consult to assess acral fixed livedo racemosa and retiform purpura presentations.
D-dimer levels exceeded 3 mcg/mL in each case. All four patients had a suspected pulmonary embolism within 1-5 days of the dermatologic findings. Prophylactic anticoagulation at admission was changed to therapeutic anticoagulation because of increasing D-dimer levels and the suspected thrombotic events.
“I think that the paper is interesting because it shows the associated histopathological findings and has important clinical implications due to the association with pulmonary embolism,” said Dr. Garcia-Doval, a researcher at the Spanish Academy of Dermatology in Madrid. “These patients should probably be anticoagulated.”
Skin biopsy results
Punch biopsies revealed pauci-inflammatory thrombogenic vasculopathy involving capillaries, venules, arterioles, or small arteries.
Livedo racemosa skin findings point to partial occlusion of cutaneous blood vessels, whereas retiform purpura indicate full occlusion of cutaneous blood vessels.
An inability to confirm the exact timing of the onset of the skin rash was a limitation of the study.
“The findings suggest that clinicians caring for patients with COVID-19 should be aware of livedoid and purpuric rashes as potential manifestations of an underlying hypercoagulable state,” the authors noted. “If these skin findings are identified, a skin biopsy should be considered because the result may guide anticoagulation management.”
Observations during an outbreak
The researchers observed these cases between March 13 and April 3, during the peak of the COVID-19 outbreak in New York.
“We did see additional cases since our study period. However, it has decreased significantly with the falling number of COVID-19 cases in the city,” said Dr. Harp, a dermatologist at NewYork–Presbyterian.
Another contributing factor in the drop in cases was “implementation of earlier, more aggressive anticoagulation in many of these patients at our institution,” she added.
The investigators plan to continue the research. “We are working on a more formalized study,” lead author Caren Droesch, MD, said in an interview.
“But given very low patient numbers in our area we have not started recruiting patients,” said Dr. Droesch, a resident at Weill Cornell Medicine and NewYork–Presbyterian at the time of the study. She is now a dermatologist at Mass General Brigham in Wellesley, Mass.
Consider a dermatology consult
“This is a small case series of four patients, but mirrors what we have seen at our institution and what others have reported about individual patients around the world,” Anthony Fernandez, MD, PhD, a dermatologist at Cleveland Clinic, said in an interview. “The skin, like many other organ systems, can be affected by thrombotic events within the setting of COVID-19 disease.”
As in the current study, Dr. Fernandez observed skin manifestations in people with severe COVID-19 with elevated D-dimer levels. These patients typically require mechanical ventilation in the intensive care unit, he added.
“As these authors point out, it is important for all clinicians caring for COVID-19 patients to look for these rashes,” said Dr. Fernandez, who coauthored a report on skin manifestations in this patient population. “We also agree that clinicians should have a low threshold for consulting dermatology. A skin biopsy is minimally invasive and can be important in confirming or refuting that such rashes are truly reflective of thrombotic vasculopathy.”
Dr. Harp, Dr. Droesch and Dr. Garcia-Doval have disclosed no relevant financial relationships. Dr. Fernandez received funding from the Clinical and Translational Science Collaborative at Case Western Reserve University to study skin manifestations of COVID-19.
