Relationship Between Frailty and Respiratory Syncytial Virus Infection in Hospitalized Older Adults.

ABSTRACT:

Background

This study aimed to evaluate the impact of frailty on clinical outcomes and disease severity of respiratory syncytial virus (RSV) infection in older adults using data from the CIRN SOS Network (Serious Outcomes Surveillance Network; Canadian Immunization Research Network).

Methods

This cohort study used data from the CIRN SOS Network collected during the 2012-2013, 2013-2014, and 2014-2015 influenza seasons. Patients aged ≥50 years who were hospitalized for acute respiratory illness were tested for RSV by multiplex reverse transcription-polymerase chain reaction. The analysis focused on frailty to assess its association with RSV disease severity and clinical outcomes. Frailty was categorized as nonfrail, prefrail, and frail according to valida
