BACKGROUND: In contrast with respiratory disease caused by influenza, information on the risk of respiratory syncytial virus (RSV) disease among adults with chronic medical conditions (CMCs) is limited. METHODS: We linked population based surveillance of acute respiratory illness hospitalizations to national administrative data, to estimate seasonal RSV hospitalization rates among adults aged 18-80 years with certain pre-existing CMCs: chronic obstructive pulmonary disease (COPD), asthma, congestive heart failure (CHF), coronary artery disease (CAD), cerebrovascular accidents (CVA), diabetes mellitus (DM), and end-stage renal disease (ESRD). Age and ethnicity adjusted rates stratified by age group were estimated. RESULTS: Among 883,999 adult residents aged 18-80 years, 281 RSV positive hospitalizations were detected during 2012-2015 winter seasons. Across all ages, RSV hospitalization rates were significantly higher among adults with COPD, asthma, CHF, and CAD compared to those without each corresponding condition. RSV hospitalization rates were significantly higher among adults with ESRD aged 50-64 years and adults with DM aged 65-80 years compared to adults in each age group without these conditions. No increased risk was seen for adults with CVA. The CMC with the highest risk of RSV hospitalization was CHF (Incidence Rate Ratio [IRR] range: 4.6-36.5 across age strata) and COPD (IRR range: 9.6-9.7). Among RSV positive adults, CHF and COPD were independently associated with increased length of hospital stay. CONCLUSIONS: Adults with specific CMCs are at increased risk of RSV hospitalizations. Age affects this relationship for some CMCs. Such populations maybe relevant for future RSV prevention strategies.
