Exploratory Study of the Usability, Feasibility, and Perception for Tele-cardiac Rehabilitation (Tele-CR) Program

Following the completion of basic characteristics assessment prior to discharge, a 12 weeks tele-CR program was implemented for all participants. The tele-CR program is divided into three parts: motivational interview, App delivery, and self-management and tracking. The motivational interviewing during hospitalization, which involved evaluating individual risk factors, setting behavioral goals, and providing training on the installation and operation of the tele-CR App (approximately 30-60 minutes per session). After discharge, the researchers monitored App usage and conducted four follow-up sessions via LINE or telephone at 1, 4, 8, and 12 weeks post-discharge. These follow-ups, lasting approximately 5-15 minutes each, aimed to assess patients' living conditions, resolve any issues promptly, and provide encouragement or praise based on their engagement with the App.
