Influenza Other Respir Viruses
January 2022
Background: Respiratory syncytial virus (RSV) infections are common in adults, but data describing the cost of RSV-associated hospitalization are lacking due to inconsistency in diagnostic coding and incomplete case ascertainment. We evaluated costs of RSV-associated hospitalization in adult patients with laboratory-confirmed, community-onset RSV.
Methods: We included adults ≥ 18 years of age admitted to three hospital systems in New York during two RSV seasons who were RSV-positive by polymerase chain reaction (PCR) and had more than or equal to two acute respiratory infection symptoms or exacerbation of underlying cardiopulmonary disease.
Objectives: Respiratory syncytial virus (RSV) causes substantial morbidity and mortality in older adults. We assessed severe clinical outcomes among hospitalized adults that were associated with RSV infections.
Methods: We performed a nested retrospective study in 3 New York City hospitals during 2 respiratory viral seasons, October 2017-April 2018 and October 2018-April 2019, to determine the proportion of patients with laboratory-confirmed RSV infection who experienced severe outcomes defined as intensive care unit (ICU) admission, mechanical ventilation, and/or death.
