Healthcare Utilization in Children Following Hospitalization for RSV- Versus Non-RSV Related Lower Respiratory Tract Infections: A Nationwide Retrospective Study.

ABSTRACT:

Introduction

Respiratory syncytial virus (RSV) is a leading cause of lower respiratory tract infections (LRTIs) in young children. Additionally, RSV is associated with long-term respiratory morbidities. This study evaluates acute and long-term healthcare utilization (HCU) in infants hospitalized with RSV-associated LRTI (RSV-LRTI) compared to non-RSV LRTI (Non-RSV-LRTI) in a nationwide cohort.

Methods

A retrospective case-control study used data from Clalit Healthcare Services (CHS), Israel's largest healthcare provider. Infants born between 2015 and 2023, admitted before 12 months of age with LRTI during the RSV season, were included.
