Hospital Admissions for Abusive Head Trauma before and during the COVID-19 Pandemic

Abstract

Importance: Several studies have demonstrated a decrease in the occurrence of child abuse in the US since the start of the COVID-19 pandemic. This finding has generated concern for missed cases due to the initial lockdowns and lack of childcare resources. Determining the association of the pandemic on hospitalizations for severe forms of abuse is essential to focus preventive efforts. Objective: To examine trends in abusive head trauma (AHT) before and during the COVID-19 pandemic. Design, Setting, and Participants: Retrospective, multicenter, repeated cross-sectional study, conducted January 1, 2016, through April 30, 2022, with data from tertiary care children's hospitals and contributors to the Pediatric Health Information System. Data were obtained for 2380 hospitalizations of children younger than 5 years with International Classification of Diseases, Tenth Revision, Clinical Modification codes for both abuse and head trauma. Main Outcomes and Measures: Monthly hospitalizations were analyzed using interrupted time-series analysis. Hospitalization severity (eg, intensive care unit stay) and clinical characteristics (subdural hemorrhages and retinal hemorrhages) were compared before and after the start of the pandemic. Results: We identified 2380 hospitalizations due to AHT (median age, 140 [IQR, 75.0-325.5] days) from 45 hospitals. The mean (SD) monthly incidence of AHT was 34.3 (5.8) before the COVID-19 pandemic compared with 25.6 (4.2) during COVID-19 (a 25.4% decrease). When the pre-COVID-19 and during COVID-19 periods were compared, there were no significant differences in severity or clinical characteristics. On interrupted time-series analysis, there was a significant decrease in the number of monthly hospitalizations (-8.1; 95% CI, -12.41 to -3.72; P
