Abstract 10506: Cardiac Rehabilitation Visits Have Not Recovered to Pre-Pandemic Levels

Abstract

Introduction: The COVID-19 pandemic led to temporary restrictions on in-person cardiac rehabilitation (CR) services to mitigate high-risk exposure. Hypothesis: In order to better understand the impact of COVID-19 restrictions on CR services, we evaluated changes in the frequency and characteristics of CR visits in 2020 compared with 2019 in a commercially-insured population. Methods: We queried the Michigan Value Collaborative statewide claims data registry for outpatient CR visits between 01/01/2019 and 12/31/2020 using CPT codes (93797, 93798) among patients with diagnoses of ischemic heart disease, heart failure, percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG), or heart valve procedure. We described monthly trends in CR visits, and used bivariate analyses to compare changes in the demographics and medical diagnoses for CR visits in 2020 compared with 2019. Results: We identified a total of 45,553 CR visits in 2019 and 30,236 visits in 2020, representing a 33.6% relative decline. Monthly CR visits reached a nadir of 138 visits in April 2020 (96.5% reduction compared with April 2019), recovered to 3072 visits in September (-17.9%), and fell again to 2434 visits in December (-34.7%) (Figure). Relative changes in CR visits from 2019 to 2020 varied by diagnosis (p<0.001): -50.3% for heart failure (2931 to 1456, -37.5% for CABG (10121 to 6329), -35.3% for PCI (19669 to 12729), -28.9% for valve surgery (5621 to 3994), and -20.6% for ischemic heart disease (7211 to 5728). There were no significant differences in patient mean age (68.0 vs. 68.1 years, p=0.62) or gender (39.8% vs. 39.9% female, p=0.839) in 2019 compared with 2020. Conclusions: Total cardiac rehabilitation visits in 2020 were 33.6% lower compared with 2019, with heterogeneity in declines by underlying eligible diagnosis. Continued monitoring is needed to understand the public health impact of reduced CR use due to the COVID-19 pandemic.
