Insights
Patient cost sharing significantly reduces cardiac rehabilitation (CR) attendance. Higher co-pays and deductibles are linked to fewer CR sessions, highlighting the need for policy reevaluation.
Area of Science:
- Cardiology
- Health Economics
- Public Health
Background:
- Cardiac rehabilitation (CR) is a vital, yet underutilized, program for cardiovascular disease recovery.
- Patient adherence to CR is crucial for optimal outcomes.
- Cost-sharing policies, including co-pays and deductibles, may impact patient engagement in healthcare services.
Purpose of the Study:
- To investigate the association between patient cost-sharing obligations and adherence to cardiac rehabilitation programs.
- To determine if household income influences the relationship between cost sharing and CR attendance.
Main Methods:
- A retrospective analysis of 603 patients enrolled in CR was conducted.
- Detailed cost-sharing data (co-pays, deductibles) were collected.
- The number of CR sessions attended was evaluated against cost-sharing variables and household income.
Main Results:
- 39% of patients faced some form of cost sharing.
- Any cost sharing was associated with 6 fewer CR sessions.
- A dose-response relationship was observed: higher co-pays correlated with significantly lower CR attendance (1.5 fewer sessions per $10 increase).
- Patients with deductibles renewing in January attended fewer sessions if hospitalized late in the year.
Conclusions:
- Cost sharing presents a significant barrier to cardiac rehabilitation adherence.
- A clear dose-response relationship exists, where increased financial burden leads to decreased participation.
- Payers and insurance companies should reconsider cost-sharing policies for CR to improve access and utilization.
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.
