A Diagnostic Prediction Model to Distinguish Multisystem Inflammatory Syndrome in Children.

OBJECTIVE: Features of multisystem inflammatory syndrome in children (MIS-C) overlap with other syndromes, making the diagnosis difficult for clinicians. We aimed to compare clinical differences between patients with and without clinical MIS-C diagnosis and develop a diagnostic prediction model to assist clinicians in identification of patients with MIS-C within the first 24 hours of hospital presentation. METHODS: A cohort of 127 patients (<21 years) were admitted to an academic children's hospital and evaluated for MIS-C. The primary outcome measure was MIS-C diagnosis at Vanderbilt University Medical Center. Clinical, laboratory, and cardiac features were extracted from the medical record, compared among groups, and selected a priori to identify candidate predictors. Final predictors were identified through a logistic regression model with bootstrapped backward selection in which only variables selected in more than 80% of 500 bootstraps were included in the final model. RESULTS: Of 127 children admitted to our hospital with concern for MIS-C, 45 were clinically diagnosed with MIS-C and 82 were diagnosed with alternative diagnoses. We found a model with four variables-the presence of hypotension and/or fluid resuscitation, abdominal pain, new rash, and the value of serum sodium-showed excellent discrimination (concordance index 0.91; 95% confidence interval: 0.85-0.96) and good calibration in identifying patients with MIS-C. CONCLUSION: A diagnostic prediction model with early clinical and laboratory features shows excellent discrimination and may assist clinicians in distinguishing patients with MIS-C. This model will require external and prospective validation prior to widespread use.

Patient and Provider Perspectives on Pediatric Telemedicine During the COVID-19 Pandemic.

The COVID-19 pandemic led to rapid expansion of telemedicine services. We surveyed parent/guardians from March 10 to June 29, 2020, in an academic and community pediatric practice, and community pediatric providers from June 5 to July 13, 2020, to better understand their perceptions of telemedicine and compare parent/guardian satisfaction between in-person and telemedicine encounters. Overall patient satisfaction scores were high in both settings and did not differ between in-person and telemedicine visits (community setting: 93.36 ± 12.87 in-person vs. 88.04 ± 22.04 telemedicine; academic setting: 92.25 ± 11.2 vs. 95.37 ± 8.21). Most providers (82.5%) would be willing to use telemedicine in a nonpandemic situation. Telemedicine should remain available for primary care pediatrics during and after resolution of the pandemic.

Improvements in appropriate ambulatory antibiotic prescribing using a bundled antibiotic stewardship intervention in general pediatrics practices.

OBJECTIVE: To improve appropriate antibiotic prescribing for children in Tennessee. DESIGN: We performed a before-and-after intervention study with 3 comparison periods: period 1 (P1, baseline) May 2018-September 2019; period 2 (P2, intervention before the COVID-19 pandemic) November 11, 2019-March 20, 2020; and period 3 (P3, intervention during the coronavirus disease 2019 [COVID-19] pandemic) March 21, 2020-November 10, 2020. We additionally surveyed participating providers to assess acceptance of the intervention. SETTING: Community general pediatrics practices. PARTICIPANTS: In total, 81 general pediatricians, family medicine physicians, and nurse practitioners in 5 general pediatrics practices participated in this study. INTERVENTIONS: Each practice identified a practice and operations champion for the project. Practices chose 2-4 implementation strategies previously shown to be effective at reducing outpatient antibiotic use to implement in their practice throughout the study intervention period. Study personnel also held quarterly meetings with all providers to review deidentified peer comparison feedback both across practices enrolled in the study and at the provider level within each practice. RESULTS: We detected improvements in guideline-concordant antibiotic use in the pre-COVID-19 intervention period, and they were sustained in the study period during the pandemic (P3): otitis media (P1 72.14% vs P2 81.42% vs P3 86.11%), group A streptococcal pharyngitis (P1 66.13% vs P2 81.56% vs P3 80.44%), pneumonia (P1 70.6% vs P2 76.2% vs P3 100%), sinusitis (P1 76.2% vs P2 83.78% vs P3 82.86%), skin and soft-tissue infections (P1 97.18% vs P2 100% vs P3 100%). CONCLUSIONS: Bundled implementation strategies led to significant increases in guideline-concordant antibiotic prescribing for all diagnoses. Survey results demonstrate that the bundled implementation strategies were well-accepted by providers.

Multisystem Inflammatory Syndrome in Children: Survey of Protocols for Early Hospital Evaluation and Management.

OBJECTIVE: To describe the similarities and differences in the evaluation and treatment of multisystem inflammatory syndrome in children (MIS-C) at hospitals in the US. STUDY DESIGN: We conducted a cross-sectional survey from June 16 to July 16, 2020, of US children's hospitals regarding protocols for management of patients with MIS-C. Elements included characteristics of the hospital, clinical definition of MIS-C, evaluation, treatment, and follow-up. We summarized key findings and compared results from centers in which >5 patients had been treated vs those in which ≤5 patients had been treated. RESULTS: In all, 40 centers of varying size and experience with MIS-C participated in this protocol survey. Overall, 21 of 40 centers required only 1 day of fever for MIS-C to be considered. In the evaluation of patients, there was often a tiered approach. Intravenous immunoglobulin was the most widely recommended medication to treat MIS-C (98% of centers). Corticosteroids were listed in 93% of protocols primarily for moderate or severe cases. Aspirin was commonly recommended for mild cases, whereas heparin or low molecular weight heparin were to be used primarily in severe cases. In severe cases, anakinra and vasopressors frequently were recommended; 39 of 40 centers recommended follow-up with cardiology. There were similar findings between centers in which >5 patients vs ≤5 patients had been managed. Supplemental materials containing hospital protocols are provided. CONCLUSIONS: There are many similarities yet key differences between hospital protocols for MIS-C. These findings can help healthcare providers learn from others regarding options for managing MIS-C.

Low In-School COVID-19 Transmission and Asymptomatic Infection Despite High Community Prevalence.

There is concern that in-person schooling during the coronavirus disease 2019 (COVID-19) pandemic will facilitate disease transmission. Through asymptomatic surveillance and contact tracing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), we found low rates of asymptomatic SARS-CoV-2 infection and little in-school transmission of COVID-19 when physical distancing and masking strategies were enforced despite a high community prevalence of COVID-19.
