Abstract
Objectives: While children represented a small percentage of those hospitalized during the COVID-19 pandemic, there was a surge of pediatric viral-related admissions in the immediate postpandemic viral season. Our study compares the epidemiology and health care utilization of children with acute respiratory infections during the 2022-2023 season to prepandemic and subsequent postpandemic seasons to see if trends persisted.
Methods: We examined administrative data for children who presented to 2 urban pediatric emergency departments (ED) during 3 periods: 2017-2020 (prepandemic), 2022-2023 (immediate postpandemic), and 2023-2024 (subsequent postpandemic). Outcomes included hospitalization rate for viral-related indications, stepdown/intensive care unit (ICU) admission, and use of advanced respiratory support. Multivariable regression controlled for demographics and specific viruses.
Results: During the study period, there were 65,313 all-cause ED encounters. Compared with prepandemic seasons, viral-related admissions doubled in 2022-2023. In addition to an increase in ED visits, the odds of viral-related admission increased by 98% [adjusted odds ratio (aOR): 1.98; 99.8% CI: 1.75-2.24], odds of stepdown/ICU admission increased by 131% (aOR: 1.31; 99.8% CI: 1.67-3.21) and odds of advanced respiratory support increased by 70% (aOR: 1.70; 99.8% CI: 1.21-2.40). In 2023-2024, the stepdown/ICU admission rate remained the same compared with 2022-2023, and the odds of advanced respiratory support increased (aOR: 1.79, 99.8% CI: 1.22-2.63). Infection with respiratory syncytial virus increased adjusted odds of more advanced care.
Conclusions: Pediatric ED visits and hospitalization rate decreased in 2023-2024 compared with the postpandemic surge, but the admission rate remained high compared with prepandemic seasons, percent admitted to stepdown/ICU persisted, and the use of advanced respiratory support continued to increase.
期刊介绍：
Pediatric Emergency Care®, features clinically relevant original articles with an EM perspective on the care of acutely ill or injured children and adolescents. The journal is aimed at both the pediatrician who wants to know more about treating and being compensated for minor emergency cases and the emergency physicians who must treat children or adolescents in more than one case in there.
