Introduction: Cardiac rehabilitation (CR) is a Class 1A recommendation post-percutaneous coronary intervention (PCI), yet it remains underutilized. At the Minneapolis VA, the referral and enrollment rates for CR post-PCI are significantly below the national goal of 70%, indicating a need for improved strategies to enhance veteran participation. Research Questions: This study investigates the impact of a workflow intervention on CR enrollment rates and seeks to understand how staffing changes may influence these rates. It also explores the potential for advanced practice providers to affect CR enrollment. Aim: We aim to increase CR enrollment to 40% and referrals to 50% post-PCI at the Minneapolis VA by August 2023, utilizing a nurse practitioner dedicated to interventional cardiology patients post-PCI. Methods: Utilizing the VA CART database, demographic data for patients undergoing PCI between October 2017 and August 2023 were analyzed, excluding those who died within 30 days of PCI. CR referrals within 90 days and enrollments within one year were tracked. Statistical process control charts were used to detect variations in referral and enrollment rates, with a t-test determining significance. The staffing change intervention occurred in May of 2020. Results: The intervention led to a significant increase in both referral and enrollment rates. The average monthly referral rate rose from 24% to 37%, and the enrollment rate from 14% to 28%. A statistical process control chart indicated special cause variation in the sample after the intervention, suggesting meaningful change. Statistical analysis confirmed these increases as significant (p<0.001). Conclusion: The staffing intervention at the Minneapolis VA significantly improved CR referral and enrollment rates post-PCI. This suggests that dedicated cardiac care providers can play a crucial role in enhancing CR utilization, potentially informing future quality improvement initiatives.
