ABSTRACT
This study was performed to evaluate the effectiveness of a hybrid, telephone-based cardiac rehabilitation (TBCR) program implemented early in the COVID-19 pandemic compared with in-person, center-based programming offered prior to the pandemic. The focus was on older adults' engagement and outcomes. Matched groups of hybrid and in-person cardiac rehabilitation (CR) participants were created from existing data and compared using t-tests and repeated measures ANOVAs. Qualitative interviews were conducted with participating CR staff then transcribed, coded, and analyzed for key themes. There were significant differences in body mass index and weight from pre-to post-CR within both hybrid and in-person groups. Despite this, CR staff believed exercise adherence was reduced in the hybrid group when compared to those in the in-person program. In the future, TBCR should be considered as an adjunct to in-person CR. Reluctance to prescribe exercise needs to be addressed through CR staff training.
