OBJECTIVES: Little is known about the costs and the effects of cardiovascular prevention programs targeted at medical and behavioral risk factors. The aim was to evaluate the cost-utility of a cardiovascular prevention program in a general sample of highly educated adults after 1 year of intervention. METHODS: The participants were randomly assigned to intervention (n = 208) and usual care conditions (n = 106). The intervention consisted of medical interventions and optional behavior-change interventions (eg, a tailored web site). Cost data were registered from a healthcare perspective, and questionnaires were used to determine effectiveness (eg, quality-adjusted life-years (QALYs)). A cost-utility analysis and sensitivity analyses using bootstrapping were performed on the intermediate results. RESULTS: When adjusting for baseline utility differences, the incremental cost was Euro 433 and the incremental effectiveness was 0.016 QALYs. The incremental cost-effectiveness ratio was 26,910 Euro /QALY. CONCLUSIONS: The intervention was cost-effective compared with usual care in this sample of highly educated adults after 1 year of intervention. Increased participation would make this intervention highly cost-effective.
