Hospitalizations Associated With Respiratory Syncytial Virus Illness Among Children and Adolescents in Ontario, Canada.

ABSTRACT:

Background

Respiratory syncytial virus (RSV) illness poses a significant burden in children yet is understudied in those >2 years old.

Methods

We identified patients aged ≤17 years hospitalized with RSV between July 2010 and March 2023 using Ontario's administrative healthcare data. RSV-specific hospitalizations were defined by ICD-10-CA codes (B97.4, J12.1, J20.5, J21.0) and included overnight stays. Key outcomes included hospitalization frequency, intensive care unit (ICU) use, mechanical ventilation, supplemental oxygen, length of stay, mortality, and costs. Risk conditions included chronic respiratory diseases, congenital malformations, and cystic fibrosis.

Results

There were 23 930 RSV hospitalizations; annual counts ranged from 1356 (2010-2011) to 4298 (2022-202
