Financial incentives and case management to improve cardiac rehabilitation participation among patients with lower socio-economic status: Rationale and protocol for a randomized controlled trial.

BACKGROUND

Participation in phase 2 cardiac rehabilitation (CR) is associated with significant decreases in morbidity and mortality. Unfortunately, attendance at CR is not optimal and certain populations, such as those with lower-socioeconomic status (SES), are less likely to participate. In order to remedy this disparity we have designed a trial to examine the efficacy of early case management and/or financial incentives for increasing CR participation among lower-SES patients.

METHODS

We will employ a randomized controlled trial with a sample goal of 209 patients who will be randomized 2:3:3:3 to either a usual care control, to receive a case manager starting in-hospital, to receive financial incentives for completing CR sessions, or to receive both interventions.

RESULTS

Treatment conditions will be compared on attendance at CR and end-of-intervention (four months) improvements in cardiorespiratory fitness, executive function, and health-related quality of life. The primary outcome measures for this project will be number of CR sessions completed and the percentage who complete ≥30 sessions. Secondary outcomes will include improvements in health outcomes by condition, as well as the cost-effectiveness of the intervention with a focus on potential reductions in emergency department visits and hospitalizations. We hypothesize that either intervention will perform better than the control and that the combination of interventions will perform better than either alone.

CONCLUSIONS

This systematic examination of interventions will allow us to test the efficacy and cost-effectiveness of approaches that have the potential to increase CR participation substantially and significantly improve health outcomes among patients with lower-SES.
