Abstract 13633: Predictors of Mental and Physical Health Outcomes of Patients Undergoing an Appointment-based Cardiac Rehabilitation Program

Abstract

Introduction: Cardiac rehabilitation (CR) is an evidence-based program to improve secondary prevention outcomes for patients with cardiovascular disease (CVD). Lower health-related quality of life is a known risk factor for worse CVD outcomes. We examined the effects of a patient-driven appointment-based CR program on health-related quality of life. Methods: We utilized data from the Yale New-Haven Health (YNHH) CR program over a 6-year period (2012-2017). Data was collected on patient demographics, clinical characteristics and socioeconomic status. The Medical Outcome Short-Form General Health Survey (SF-36) was used to measure general health status. We evaluated SF-36 score changes pre and post CR with paired T-tests and conducted logistic regression analysis to examine predictors of improvements in health-related quality of life. Results: Over the 6-year study period, a total of 2,135 patients (27.9% women, mean age 65±12 years) were enrolled in the CR program. Patients demonstrated significant improvements in both the SF-36 physical, mental and health transition components (P<0.001) (Table) . In particular, patients had significant improvement in the social functioning domain (measures limitations patients see in their ability to participate in social activities due to physical/emotional issues), with an increase of 23.3 points out of 100. Physician-reported patient stress and/or depression on intake medical exam were significant negative predictors for improvement in the total SF-36 score (OR 0.23, 95% CI 0.08-0.80, P=0.021), with the effect driven largely by its impact on the physical component of SF-36 (OR 0.27, 95% CI 0.09-0.83, P=0.022). Conclusion: We demonstrated that a novel appointment-based CR program produced improvements in patient-reported health-related quality of life. Appointment-based CR could be a viable alternative for patients who prefer more scheduling flexibility, to optimize health status improvement and CVD outcomes.
