Construction of a Service Quality Assessment Indicator System for Home-based Rehabilitation APP for Heart Failure Patients

Background Nowadays, cardiac rehabilitation is mostly transferred from the hospital to a home environment. Mobile health applications assist patients in bridging the support gap from hospital to home environment, which encourages home-based recovery processes. Unfortunately, numerous quality difficulties accompany its promise, and the service quality of cardiac rehabilitation applications must be ＂confirmed＂ as soon as possible. Objective To develop a quality assessment indicator system for home-based rehabilitation APP services for heart failure patients, and to provide a model for standardizing and increasing the quality of mobile health APP. Methods This study was conducted from July 2022 to January 2023, using semi-structured interviews, literature review, the expert consultation method and analytic hierarchy process (AHP) to determine the content of indicator system and the weight for each index. Results 2 rounds of expert consultations resulted in the effective response rates of 100%, with the authority coefficients of 0.867, and the coordination coefficients of 0.128-0.154 and 0.151-0.197 respectively (P
