Abstract 12914: Effect of Home-Based versus Center-Based Cardiac Rehabilitation Among Attendees From a Large Healthcare System During the Covid-19 Pandemic

Abstract

Introduction: The COVID-19 pandemic imposed significant constraints to delivery of cardiac rehabilitation (CR) with many programs relying on delivery of home-based cardiac rehabilitation (HBCR). We sought to compare the effects of HBCR vs conventional center-based CR (CBCR) on clinical metrics, health-related quality of life, and modifiable risk factors in CR patients. Methods: Retrospective cohort study comparing 511 HBCR patients (March 2020-April 2021; COVID-19 pandemic) and 765 age and sex matched CBCR patients (Jan 2018-Jan2020; immediately pre-pandemic) from the Mayo Clinic Health System. We assessed changes in clinical outcomes before and after CR. HBCR included 12 sessions (one in-person assessment + weekly education and exercise monitoring phone/video calls). Conventional CBCR included 36 sessions (3 sessions per week for 12 weeks). Continuous data were described as mean±SD, and comparisons of change between groups were assessed with linear regression adjusting for baseline value, in complete cases. Results: HBCR and CBCR patients were 65±14 yrs old (68% male) and 65±14 yrs old (67% male) respectively. HBCR patients demonstrated greater improvement in exercise days/week whereas CBCR patients had greater improvement in exercise min/day. HBCR patients had greater improvement in blood glucose with a trend towards greater improvement in non-HDL cholesterol. Both groups demonstrated similar improvement on nutrition, depression, health-related quality of life surveys and total, LDL and HDL cholesterol, as well as HbA1c between the groups. Conclusions: Collecting clinical metrics during the COVID-19 pandemic proved challenging due to the initial closure of out-patient services. For patients in whom data was captured, HBCR appears to be similarly effective at improving several intermediate outcomes compared to CBCR. HBCR may be an effective alternative for improving clinical outcomes in patients who are unable to participate in CBCR.
