“…Very few randomized controlled trials (RCTs) of the effect of telehealth for cardiac surgery patients have been reported. Intervention research more commonly has focused on cardiac rehabilitation (Ades et al, ), heart failure (Benatar, Bondmass, Ghitelman, & Avitall, ), and hypertension (Artinian, Washington, & Templin, ). In one study of telehealth for CABG patients, Barnason et al () found that CABG surgery patients who used an electronic device—the Health Buddy® (HB®)—capable of transmitting health information to a central station for interpretation ( n = 35) reported higher self‐efficacy scores and improved physical, general health, and vitality function scores ( p < .05) over a 3‐month study period than did patients receiving routine in‐patient education.…”
