About

Participation in outpatient cardiac rehabilitation (CR) decreases morbidity and mortality for patients hospitalized with myocardial infarction, coronary bypass surgery or percutaneous revascularization. Unfortunately, only 10-35% of patients for whom CR is indicated choose to participate. Medicaid coverage and similar state-supported insurance are robust predictors of CR non-participation. There is growing recognition of the need to increase CR among patients with this form of insurance and other economically disadvantaged patients, but there are no evidence-based interventions available for doing so. In the present study we are examining the efficacy of using financial incentives for increasing CR participation among Medicaid patients. Financial incentives have been highly effective in altering other health behaviors among disadvantaged populations (e.g., smoking during pregnancy, weight loss). For this study are randomizing 130 CR-eligible Medicaid enrollees to a treatment condition where they receive financial incentives contingent on initiation of and continued attendance at CR sessions or to a "usual-care" condition where they will not receive these incentives. Treatment conditions will be compared on attendance at CR and end-of-intervention improvements in fitness, decision making and health-related quality of life. Cost effectiveness of the treatment conditions will also be examined by comparing the costs of the incentive intervention and usual care conditions with their effects on increasing CR initiation and adherence. Should this intervention be efficacious and cost-effective, it has the potential to substantially increase CR participation and significantly improve health outcomes among low-income cardiac patients.
