“As du Coeur” study: a randomized controlled trial on quality of life impact and cost effectiveness of a physical activity program in patients with cardiovascular disease

Background Physical activity programs (PAP) in patients with cardiovascular disease require evidence of cost-utility. To assess improvement in health-related quality of life (QoL) and reduction of health care consumption of patients following PAP, a randomized trial was used. Methods Patients from a health insurance company who had experienced coronary artery disease or moderate heart failure were invited to participate ( N = 1891). Positive responders ( N = 50) were randomly assigned to a progressively autonomous physical activity (PAPA) program or to a standard supervised physical activity (SPA) program. The SPA group had two supervised sessions per week over 5 months. PAPA group had one session per week and support to aid habit formation (written tips, exercise program, phone call). To measure health-related quality of life EQ-5D utility score were used, before intervention, 6 months (T6) and 1 year later. Health care costs were provided from reimbursement databases. Results Mobility, usual activities and discomfort improved significantly in both group (T6). One year later, EQ-5D utility score was improved in the PAPA group only. Total health care consumption in the intervention group decreased, from a mean of 4097 euros per year before intervention to 2877 euros per year after ( p = 0.05), compared to a health care consumption of 4087 euros and 4180 euros per year, in the total population of patients ( N = 1891) from the health insurance company. The incremental cost effectiveness ratio was 10,928 euros per QALYs. Conclusion A physical activity program is cost-effective in providing a better quality of life and reducing health care consumption in cardiovascular patients.
