Echocardiograms and bed placement in patients with multisystem inflammatory syndrome in children.

Background: Understanding of multisystem inflammatory syndrome in children (MIS-C) continues to evolve with extensive evaluations, including echocardiograms, obtained in emergency departments (EDs) to assist with clinical decision making and bed allocation. We assessed the utility of obtaining echocardiograms in the ED to assist in determining bed placement for this patient population. Methods: This 2-year retrospective single-center study of patients 0-21 years old without underlying cardiac disease hospitalized for MIS-C focused on individuals whose initial evaluation occurred in the institution's ED and whose echocardiogram was obtained either in the ED or within 24 hours of admission. Patients were placed in two cohorts-those remaining in their unit of admission without transfer (cohort WoT) and those transferred (cohort T) from their initial unit to one with a differing level of care within 24 hours. Pearson chi-square test assessed the relationship between echocardiogram status and appropriate bed placement, defined as no transfer within 24 hours. Results: Of the 60 patients who met study criteria, no significant difference was detected in rates of transfer between patients whose echocardiograms were obtained in the ED versus those obtained within 24 hours of admission (odds ratio =2.08; 95% confidence interval: 0.58, 7.95; P=0.28). Conclusions: Cardiac involvement is a known complication of MIS-C; however, our study yields no evidence in favor of obtaining echocardiograms in the ED to ensure appropriate bed placement. While this modality remains integral in evaluation and management, it does not appear to be requisite as part of an emergent workup prior to admission.
