Why the study?
Prescribed exercise is effective across cardiovascular diseases and risk factors, but evidence for its cost-effectiveness is limited, highly variable, and partly contradictory.
Is exercise therapy cost-effective in patients with coronary heart disease, chronic heart failure, and associated risk factors?
Is exercise therapy cost-effective in patients with coronary heart disease, chronic heart failure, and associated risk factors?
Exercise therapy appears highly cost-effective for patients with CHD, CHF, intermittent claudication, or elevated BMI, though reporting standards in economic evaluations vary.
May inform resource allocation decisions for exercise programs; leaves open questions on generalizability across settings and populations.
Aims Prescribed exercise is effective in adults with coronary heart disease (CHD), chronic heart failure (CHF), intermittent claudication, body mass index (BMI) ≥25 kg/m 2 , hypertension or type 2 diabetes mellitus (T2DM), but the evidence for its cost-effectiveness is limited, shows large variations and is partly contradictory. Using World Health Organization and American Heart Association/American College of Cardiology value for money thresholds, we report the cost-effectiveness of exercise therapy, exercise training and exercise-based cardiac rehabilitation. Methods Electronic databases were searched for incremental cost-effectiveness and incremental cost–utility ratios and/or the probability of cost-effectiveness of exercise prescribed as therapy in economic evaluations conducted alongside randomized controlled trials (RCTs) published between 1 July 2008 and 28 October 2018. Results Of 19 incremental cost–utility ratios reported in 15 RCTs in patients with CHD, CHF, intermittent claudication or BMI ≥25 kg/m 2 , 63% met both value for money thresholds as ‘highly cost-effective’ or ‘high value’, with 26% ‘not cost-effective’ or of ‘low value’. The probability of intervention cost-effectiveness ranged from 23 to 100%, probably due to the different populations, interventions and comparators reported in the individual RCTs. Confirmation with the Consolidated Health Economic Evaluation Reporting checklist varied widely across the included studies. Conclusions The findings of this review support the cost-effectiveness of exercise therapy in patients with CHD, CHF, BMI ≥25 kg/m 2 or intermittent claudication, but, with concerns about reporting standards, need further confirmation. No eligible economic evaluation based on RCTs was identified in patients with hypertension or T2DM.
