Improved Cardiac Rehabilitation Referral Rates following Coronary Artery Bypass Graft and Heart Valve Replacement in an Inner-City Veteran Population.

Cardiac rehabilitation (CR) is underutilized due to various barriers, despite its known benefits in decreasing 5-year mortality after cardiac surgery. The authors initiated a quality improvement project to identify barriers and enhance CR referral rates and participation. The team conducted a retrospective review of cardiac surgery patients from 2015 to 2022 at the Detroit Veterans Affairs. Phase 1 covered 2015-2017 (preintervention), phase 2 was the intervention period, and phase 3 covered 2018-2022 (postintervention). Appropriate CR referral was defined as within 6 months postevent. Referral rates and 1-year post-op hospitalization were assessed. Group 1 (2015-2017) had 54 male patients, 44% Black, 89% hypertensive, with a 22% CR referral rate. Group 2 (2018-2022) had 98 male patients, 64% Caucasian, mean age 73 years, with a 36% CR referral rate postintervention ( P = 0.0018). One-year hospitalization decreased from 26% to 13% ( P = 0.20). CR is still an underutilized tool. Provider education and complete funding of CR can improve referral rates and participation.
