Comparison of Intravenous Palivizumab and Standard of Care for Treatment of Respiratory Syncytial Virus Infection in Mechanically Ventilated Pediatric Patients

OBJECTIVES: Evidence suggests palivizumab may be beneficial for respiratory syncytial virus (RSV) infection in pediatric patients, although it is only approved by the US Food and Drug Administration for RSV prophylaxis. The objective of this study is to compare outcomes among pediatric patients with RSV infection who received intravenous palivizumab and standard of care versus standard of care alone. METHODS: This is a retrospective, single-center cohort study conducted between November 2003 and October 2013. Pediatric patients with active RSV infection treated with intravenous (IV) palivizumab after initiation of mechanical ventilation were matched 1:1 to a control selected from ventilated patients who received standard of care. The primary end point evaluated the duration of mechanical ventilation between groups. Secondary end points included hospital length of stay, intensive care unit length of stay, duration of respiratory support over baseline, time to RSV microbiologic cure, duration of antibiotic ...
