Abstract

Objective: To determine the association between cost sharing and adherence to cardiac rehabilitation (CR). Patients and Methods: We collected detailed cost-sharing information for patients enrolled in CR at Baystate Medical Center in Springfield, Massachusetts, including the presence (or absence) and amounts of co-pays and deductibles. We evaluated the association between cost sharing and the total number of CR sessions attended as well as the influence of household income on CR attendance. Results: In 2015, 603 patients enrolled in CR had complete cost-sharing information. In total, 235 (39%) had some form of cost sharing. Of these, 192 (82%) had co-pays (median co-pay, $20; interquartile range [IQR], $10-$32) and 79 (34%) had an unmet deductible (median, $500; IQR, $250-$1800). The presence of any amount or form of cost sharing was associated with 6 fewer sessions of CR (16; IQR, 4-36 vs 10; IQR, 4-27; P<.001). Patients hospitalized in November or December with deductibles that renewed in January attended 4.5 fewer sessions of CR (8.5; IQR, 3.25-12.50 vs 13; IQR, 5.25-36.00; P=.049). After adjustment for differences in baseline characteristics, every $10 increase in co-pay was associated with 1.5 (95% CI, −2.3 to −0.7) fewer sessions of CR (P<.001). Household income did not moderate these relationships. Conclusion: Cost sharing was associated with lower CR attendance and exhibited a dose-response relationship such that higher cost sharing was associated with lower CR attendance. Given that CR is cost-effective and underutilized, insurance companies and other payers should reevaluate their cost-sharing policies for CR.
