Hospitalization patterns for adolescents with eating disorders during COVID-19

Abstract

Purpose: The purpose of this study was to examine differences in clinical characteristics and hospital length of stay (LOS) for adolescents with eating disorders (EDs) requiring medical stabilization during the pre-COVID-19 and COVID-19 time periods. Methods: Medical record data were abstracted for patients with EDs hospitalized for medical stabilization between 1/1/2019–2/29/2020 (pre-COVID-19) and 3/1/2020–12/31/2021 (during COVID-19). Patient demographics, clinical characteristics and LOS were compared between COVID-19 eras. Patients were categorized as boarding if they remained hospitalized ≥ 1 day after medical stabilization. Multivariate negative binomial linear regression models were performed to determine incidence rate ratios (IRR) and 95% confidence intervals (95% CI) for factors related to increased LOS. Results: Of the 467 admissions during this study, 120 were pre-COVID-19 and 347 were during COVID-19. Monthly admissions for EDs were higher during COVID-19 versus pre-COVID-19 (15.8 vs. 8.6, p = 0.001). On multivariate analysis, factors associated with increased LOS included admission during COVID-19 (IRR 1.27, 95% CI 1.15–1.40), p = 0.001), boarding (IRR 1.77, 95% CI 1.63–1.93, p = 0.001), public insurance (IRR 1.12, 95% CI 1.01–1.23, p = 0.032), nasogastric tube usage (IRR 1.62, 95% CI 1.48–1.76, p = 0.001), heart rate < 40 beats per minute (IRR 1.21, 95% CI 1.11–1.33, p = 0.001) and abnormal electrocardiogram (IRR 1.25, 95% CI 1.14–1.37, p = 0.001). Conclusion: In addition to clinical factors, we found that admission during COVID-19, boarding, and public insurance were associated with increased LOS among patients with EDs. There is a need for greater availability of ED treatment centers to care for patients with EDs after medical stabilization.
