This study assessed the severity and medical resource utilization (MRU) of influenza and RSV in hospitalized adults in the United States. The findings showed that RSV patients had longer hospital stays, required more oxygen supplementation, and had higher rates of antibiotic and steroid use post-discharge compared to influenza patients. Many patients with core risk factors needed readmission within 3 months post-discharge.
Background Influenza and respiratory syncytial virus (RSV) are associated with substantial morbidity and mortality in the United States. We assessed risk factors for severe disease and medical resource utilization (MRU) among US adults hospitalized with influenza or RSV in the Hospitalized Acute Respiratory Tract Infection (HARTI) study. Methods HARTI was a prospective global (40 centers, 12 countries) epidemiological study of adults hospitalized with acute respiratory tract infections conducted across the 2017-2019 epidemic seasons. Patients with confirmed influenza or RSV were followed up to 3 months post-discharge. Baseline characteristics, prevalence of core risk factors (CRFs) for severe disease (age >= 65 years, chronic heart or renal disease, chronic obstructive pulmonary disease, or asthma), and MRU were summarized descriptively. Results The US cohort included 280 influenza-positive and 120 RSV-positive patients. RSV patients were older (mean: 63.1 vs. 59.7 years) and a higher proportion had CRFs (87.5% vs. 81.4%). Among those with CRFs (influenza, n = 153; RSV, n = 99), RSV patients required longer hospitalizations (median length of stay: 4.5 days) and a greater proportion (79.8%) required oxygen supplementation during hospitalization compared with influenza patients (4.0 days and 59.5%, respectively). At 3 months post-discharge, a greater proportion of RSV patients with CRFs reported use of antibiotics, antitussives, bronchodilators, and inhaled and systemic steroids versus those with influenza and CRFs. Many patients with CRFs reported hospital readmission at 3 months post-discharge (RSV: 13.4%; influenza: 11.9%). Conclusions MRU during and post-hospitalization due to RSV in adults is similar to or greater than that of influenza. Enhanced RSV surveillance and preventive and therapeutic interventions are needed.
