Effectiveness of Telehealth Cardiac Rehabilitation Programs on Health Outcomes of Patients With Coronary Heart Diseases

Abstract

Purpose: The aim of this study was to conduct an umbrella review summarizing the evidence from existing systematic reviews of telehealth cardiac rehabilitation (CR) on health outcomes of patients with coronary heart disease (CHD). Review Methods: An umbrella review of systematic reviews was undertaken in accordance with the PRISMA and JBI guidelines. A systematic search was conducted in Medline, APA PsycINFO, Embase, CINAHL, Web of Science, Cochrane database of systematic reviews, JBI evidence synthesis, Epistemonikos, and PROSPERO, searching for systematic reviews published from 1990 to current and was limited to the language source of English and Chinese. Outcomes of interest were health behaviors and modifiable CHD risk factors, psychosocial outcomes, and other secondary outcomes. Study quality was appraised using the JBI checklist for systematic reviews. A narrative analysis was conducted, and meta-analysis results were synthesized. Summary: From 1301 identified reviews, 13 systematic reviews (10 meta-analyses) comprised 132 primary studies conducted in 28 countries. All the included reviews have high quality, with scores ranging 73-100%. Findings to the health outcomes remained inconclusive, except solid evidence was found in the significant improvement in physical activity (PA) levels and behaviors from telehealth interventions, exercise capacity from mobile health (m-health) only and web-based only interventions, and medication adherence from m-health interventions. Telehealth CR programs, work adjunct or in addition to traditional CR and standard care, are effective in improving health behaviors and modifiable CHD risk factors, particularly in PA. In addition, it does not increase the incidence in terms of mortality, adverse events, hospital readmission, and revascularization.
