CLINICAL OUTCOMES FOLLOWING EXERCISE REHABILITATION IN PEOPLE WITH MULTIMORBIDITY: A SYSTEMATIC REVIEW

Abstract

Objective: To determine the effectiveness of exercise rehabilitation in people with multimorbidity. Exercise capacity was the primary outcome. Secondary outcomes were: health-related quality of life, activities of daily living, cardiometabolic outcomes, mental health outcomes, symptom scores, resource utilization, health behaviours, economic outcomes, and adverse events. Data sources: A search was conducted in MEDLINE, CINHAL, EMBASE, and Cochrane Central Register of Controlled Trials databases. Study selection and extraction: Randomized and non-randomized controlled trials and cohort studies of exercise rehabilitation vs any comparison in people with multimorbidity. Data synthesis: Forty-four reports (38 studies) were included. Rehabilitation ranged from 8 weeks to 4 years, with 1–7 sessions of rehabilitation weekly. Exercise included aerobic and resistance, limb training, aquatic exercises and tai chi. Compared with usual care, exercise rehabilitation improved 6-min walk distance (weighted mean difference (WMD) 64 m, 95% CI 45–82) and peak oxygen consumption (WMD 2.74 mL/kg/min, 95% CI –3.32 to 8.79). Effects on cardiometabolic outcomes and health-related quality of life also favoured rehabilitation; however; few data were available for other secondary outcomes. Conclusion: In people with multimorbidity, exercise rehabilitation improved exercise capacity, health-related quality of life, and cardiometabolic outcomes.
