Effectiveness of a Home-Based Telehealth Exercise Training Program for Patients With Cardiometabolic Multimorbidity

Background Exercise training has positive effects on the management of cardiometabolic conditions. Little is known about the effectiveness of home-based telehealth exercise training programs among patients with cardiometabolic multimorbidity, which is associated with functional decline and decreased health-related quality of life. Objective The aim of this study was to determine the effectiveness of a 12-week home-based telehealth exercise training program designed to increase physical activity and exercise capacity and improve health-related quality of life in patients with cardiometabolic multimorbidity. Methods A randomized controlled trial was conducted. Fifty eligible patients with 2 or more cardiometabolic conditions from outpatient clinics of a medical center in Northern Taiwan were randomized to either an experimental group (EG; received a 12-week home-based telehealth exercise training program) or a control group (CG; maintained usual lifestyles). The home-based telehealth exercise training program consisted of 36 individualized home-based exercise training sessions and a weekly reminder for maintenance of exercise and providing patient support. Amounts of physical activity, exercise capacity, and health-related quality of life were assessed at baseline and 12 weeks. Generalized estimating equations were used to examine the intervention effects via the interaction of time and group. Results The EG had higher amounts of physical activity (β = 1333, P = .004) and moderate-intensity physical activity (β = 330, P = .04) than the CG after the intervention. The EG had increased exercise capacity (VO2peak, β = 4.43, P = .04), as well as improved health-related quality of life (physical function, β = 7.55, P = .03; and physical component summary, β = 4.42, P = .03) compared with those in the CG. Conclusions A 12-week home-based telehealth exercise training program is feasible and effective in increasing amounts of physical activity, elevating exercise capacity, and improving health-related quality of life in patients with cardiometabolic multimorbidity.
