BackgroundTo investigate impacts of COVID-19 on CR delivery around the globe, including effects on providers and patients.MethodsIn this cross-sectional study, a piloted survey was administered to CR programs globally via REDCap from April-June/2020. The 50 members of the ICCPR and personal contacts facilitated program identification.ResultsOverall, 1062(18.3% program response rate) responses were received from 70/111(63.1% country response rate) countries in the world with existent CR programs. Of these, 367(49.1%) programs reported they had stopped CR delivery, and 203(27.1%) stopped temporarily (mean=8.3±2.8weeks). Alternative models were delivered in 322(39.7%) programs, primarily through low-tech modes (n=226,19.3%). 353(30.2%) respondents were re-deployed, and 276 (37.3%) felt the need to work due to fear of losing their job, despite the perceived risk of contracting COVID-19 (mean=30.0%±27.4/100). 266(22.5%) reported anxiety, 241(20.4%) were concerned about exposing their family, 113(9.7%) reported increased workload to transition to remote delivery, and 105(9.0%) were juggling caregiving responsibilities during business hours. Patients were often contacting staff regarding grocery shopping for heart-healthy foods (n=333,28.4%), how to use technology to interact with the program (n=329,27.9%), having to stop their exercise because they have no place to exercise (n=303,25.7%), and their risk of death from COVID-19 due to pre-existing cardiovascular disease (n=249,21.2%). Respondents perceived staff (n=488,41.3%) and patient (n=453,38.6%) personal protective equipment, as well as COVID-19 screening (n=414,35.2%) and testing (n=411,35.0%) as paramount to in-person service resumption.ConclusionApproximately 4400 programs ceased service delivery. Those that remain open are implementing new technologies to ensure their patients receive CR safely, despite the challenges.Highlights-COVID-19 has impacted cardiac rehabilitation (CR) delivery around the globe.-In this cross-sectional study, a survey was completed by 1062 (18.3%) CR programs from 70 (63.1%) countries.-The pandemic has resulted in cessation of ∼75% of CR programs, with others ceasing initiation of new patients, reducing components delivered, and/or changing of mode delivery with little opportunity for planning and training.-There is also significant psychosocial and economic impact on CR providers.-Alternative CR model (e.g. home-based, virtual) reimbursement advocacy is needed, to ensure safe, accessible secondary prevention delivery.
