Augmented exercise in hospital improves physical performance and reduces negative post hospitalization events: a randomized controlled trial

BMC Geriatr. 2020 Feb 7;20(1):46. doi: 10.1186/s12877-020-1436-0.


Background: To measure the effects of an augmented prescribed exercise programme versus usual care, on physical performance, quality of life and healthcare utilisation for frail older medical patients in the acute setting.

Methods: This was a parallel single-blinded randomised controlled trial. Within 2 days of admission, older medical inpatients with an anticipated length of stay ≥3 days, needing assistance/aid to walk, were blindly randomly allocated to the intervention or control group. Until discharge, both groups received twice daily, Monday-to-Friday half-hour assisted exercises, assisted by a staff physiotherapist. The intervention group completed tailored strengthening and balance exercises; the control group performed stretching and relaxation exercises. Length of stay was the primary outcome measure. Blindly assessed secondary measures included readmissions within 3 months, and physical performance (Short Physical Performance Battery) and quality of life (EuroQOL-5D-5 L) at discharge and at 3 months. Time-to-event analysis was used to measure differences in length of stay, and regression models were used to measure differences in physical performance, quality of life, adverse events (falls, deaths) and negative events (prolonged hospitalisation, institutionalisation).

Results: Of the 199 patients allocated, 190 patients' (aged 80 ± 7.5 years) data were analysed. Groups were comparable at baseline. In intention-to-treat analysis, length of stay did not differ between groups (HR 1.09 (95% CI, 0.77-1.56) p = 0.6). Physical performance was better in the intervention group at discharge (difference 0.88 (95% CI, 0.20-1.57) p = 0.01), but lost at follow-up (difference 0.45 (95% CI, - 0.43 - 1.33) p = 0.3). An improvement in quality of life was detected at follow-up in the intervention group (difference 0.28 (95% CI, 0.9-0.47) p = 0.004). Overall, fewer negative events occurred in the intervention group (OR 0.46 (95% CI 0.23-0.92) p = 0.03).

Conclusion: Improvements in physical performance, quality of life and fewer negative events suggest that this intervention is of value to frail medical inpatients. Its effect on length of stay remains unclear.
