Brief summary

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. Lower socioeconomic status (SES) is a robust predictor of CR non-participation. There is growing recognition of the need to increase CR among economically disadvantaged patients, but there are almost no evidence-based interventions available for doing so. The present study will examine the efficacy of using early case management and financial incentives for increasing CR participation among lower-SES patients. Case management has been effective at promoting attendance at a variety of health-related programs (e.g. treatment for diabetes, HIV, asthma, cocaine dependence) as well as reducing hospitalizations. Financial incentives are also highly effective in altering health behaviors among disadvantaged populations (e.g., smoking during pregnancy, weight loss) including CR participation in a prior trial. For this study 209 CR-eligible lower-SES patients will be randomized to: a treatment condition where patients are assigned a case manager while in hospital who will facilitate CR attendance and coordinate cardiac care, a treatment condition where patients receive financial incentives contingent on initiation of and continued attendance at CR sessions, a combination of these two interventions, or to a usual-care condition. Participants in all conditions will complete pre- and post-treatment assessments. Treatment conditions will be compared on attendance at CR and end-of-intervention improvements in fitness, executive function, and health-related quality of life. Cost effectiveness of the treatment conditions will also be examined by comparing the costs of delivering the interventions and the usual care condition, taking into account increases in CR participation. Furthermore, the value of the interventions will be modeled based on increases in participation rates, intervention costs, long-term medical costs, and health outcomes after a coronary event. This systematic examination of promising interventions will allow testing of the efficacy and cost-effectiveness of approaches that have the potential to substantially increase CR participation and significantly improve health outcomes among lower-SES cardiac patients.

Cost-effectiveness

Cost-effectiveness of the intervention will be determined. Cost-effectiveness is a single outcome (cost per per quality-adjusted life year gained) that is calculated by integrating the cost of delivering the intervention, the cost to the patient of receiving the intervention, and the benefits both in quality of life and in reductions in healthcare utilization.

Time frame: One year period starting at intake assessment.

Other Pre-specified

Maintenance of Depressive Symptoms Following Intervention.

Changes in reported depressive symptoms The Beck Depression Inventory (BDI) will be measured from intervention completion until follow-up (8 months after intervention completion). BDI results will be back transformed due to data being square root transformed. Scores range from 0 to 63, with higher scores indicating worse outcomes.

Time frame: From completion of intervention (4 months) to follow-up (one-year).

Other Pre-specified

Maintenance of Executive Function (BRIEF) Following Intervention.

Changes in self-reported Executive function problems (BRIEF) will be measured from intervention completion until follow-up (8 months after intervention completion). The Global Executive Composite (GEC) of the Behavior Rating Inventory of Executive Function (BRIEF) was used. T-scores are reported. A T-score of 50 indicates the population mean, and 10 is the standard deviation. Higher T-scores indicate worse outcomes. T-scores above 65 indicate clinically significant problems.

Time frame: From completion of intervention (4 months) to follow-up (one-year).

Other Pre-specified

Maintenance of Executive Function (Delay Discounting) Following Intervention.

Changes in Executive function (delay discounting) will be measured from intervention completion until follow-up (8 months after intervention completion). A 5-trial adjusting delay discounting task will be used to calculate k values, numerical representations of the rate of discounting. k values range from 0 to 0.5, with larger values indicating steeper discounting (more impulsivity; greater propensity to devalue delayed rewards in favor of more immediate outcomes). k values were log(10) transformed for analysis. Larger log transformed k values indicate steeper discounting.

Time frame: From completion of intervention (4 months) to follow-up (one-year).

Other Pre-specified

Maintenance of Executive Function (DS) Following Intervention.

Changes in Executive function (digit span) will be measured from intervention completion until follow-up (8 months after intervention completion). The Digit Span subtest of the Wechsler Adult Intelligence Scale-IV (WAIS-IV) was used. Scores range from 1 to 19, with higher scores indicating worse outcomes.

Time frame: From completion of intervention (4 months) to follow-up (one-year).

Other Pre-specified

Maintenance of Executive Function (SST) Following Intervention.

Changes in Executive function (stop signal task) will be measured from intervention completion until follow-up (8 months after intervention completion).

Time frame: From completion of intervention (4 months) to follow-up (one-year).

Other Pre-specified

Maintenance of Executive Function (Trail) Following Intervention.

Changes in Executive function (trail making task) will be measured from intervention completion until follow-up (8 months after intervention completion). The Trail-Making subtest of the Delis-Kaplan Executive Function System (D-KEFS) was used. Scores range from 1 to 19, with higher scores indicating worse outcomes.

Time frame: From completion of intervention (4 months) to follow-up (one-year).

Other Pre-specified

Maintenance of Fitness Following Intervention (Estimated Metabolic Equivalent of Task)

Changes in fitness level (Estimated Metabolic Equivalent of Task) will be measured from intervention completion until follow-up (8 months after intervention completion).

Time frame: From completion of intervention (4 months) to follow-up (one-year).

Population: Overall number of participants analyzed represents the total number of participants from each arm of the study who completed this measure and for whom data were collected.
