Fattori di rischio per l'ammissione in terapia intensiva nei bambini ospedalizzati con infezione da virus respiratorio sinciziale.

OBJECTIVES: To analyze the clinical characteristics of hospitalized children with respiratory syncytial virus (RSV) infection and identify independent risk factors for intensive care unit (ICU) admission. METHODS: This retrospective study included hospitalized children with polymerase chain reaction (PCR)-confirmed RSV infection between July 2022 and April 2025. Epidemiological, clinical, laboratory, and imaging data were collected. Multivariable logistic regression analysis was employed to determine independent predictors of ICU admission. RESULTS: Of 95,311 children tested for acute respiratory infections, 14,583 (15.3%) were RSV-positive, of whom 5,814 (39.9%) were hospitalized. The hos
