Background/Objectives: The importance of RSV infection among adults admitted to secondary care is not well defined. Objectives were to identify patient demographics and co-morbidities and relate findings to length of hospital stay (LOS). Method(s): A retrospective review of adults admitted to one NHS trust with confirmed RSV (PCR respiratory swabs), identified during 3 months until 31st January 2017, coinciding with the UK winter. Result(s): Peak incidence was the 3rd week of December 2016 whilst later with Influenza (n=145) and earlier with paediatric admissions with RSV (n=3) throughout the study. Mean (SD, range) age of admitted adult patients (n=50) was 68.9 (19.5, 23-96) years with 27 (54%) female and LOS 8.8 (9.6, 0-41) days. 3 (6%) had concurrent RSV/Influenza A infection. 46 (92%) were admitted from home mainly via A&E (60%), General Practitioner (28%), and ambulatory care (8%). 73.5% had at least four co-morbidities, predominantly cardiorespiratory (50%) with a longer LOS (10.7 days), but also diabetes (20%), dementia (10%), malignancy (20%), and immunosuppression (10%). LOS correlated (Spearman rho) positively with both age (r =0.481, p<0.001) and number of co-morbidities (r< =0.486, p<0.0001). LOS was shorter where RSV was a primary as opposed to concurrent diagnosis (6.13, 0-21 vs 13.8, 1-41) days. Conclusion(s): RSV was detected at greater numbers during different times of the three month period among hospital admissions compared with paediatric RSV and influenza admissions, suggesting a staggered temporal relationship. Increasing age and the number of co-morbidities, predominantly cardio-respiratory, correlated positively with longer LOS.
