Background: Regional quality improvement collaboratives may provide one solution to improving cardiac rehabilitation (CR) participation through performance benchmarking and provider engagement. The objective of this descriptive study was to evaluate the feasibility of the Michigan Cardiac Rehab Consortium to improve CR participation Methods and Results: Multipayer claims data from the Michigan Value Collaborative were used to identify hospitals and CR facilities. Univariate analyses described participating hospital characteristics and hospital-level rates of CR enrollment within 1-year. A total of 95 hospitals and 85 CR facilities with 48 hospitals (51%) providing interventional cardiology services and 33 (35%) provided cardiac surgical services. The overall consortium-wide enrollment rate into CR across all conditions was 19.8% (26,398 of 133,641 eligible admissions), which was highest for CABG (58.4%), followed by SAVR (54.8%), PCI (34.6%), TAVR (33.1%), AMI (12.7%), and CHF (3.4%). There was wide variation in CR participation across participating eligible admissions and hospitals (Figure). A 17-member multidisciplinary stakeholder group was assembled representing 12 institutions and diverse roles, including exercise physiologists, cardiologist, program directors, and patients. Three diverse CR facilities participated in virtual site visits, which revealed individual successes in improving CR participation, but a variety of barriers to participation related to referrals, capacity and staffing constraints, and geographic and financial barriers. Conclusions: This study demonstrated the feasibility of a statewide collaboration centered around the goal of equitably improving CR enrollment for all eligible patients that is supported by a multidisciplinary stakeholder group and performance benchmarking. Future work will seek to continuously improve and evaluate the impact of this consortium on CR participation in Michigan.
