Influence of a symptom management telehealth intervention on older adults' early recovery outcomes after coronary artery bypass surgery.
OBJECTIVE The study objective was to examine the effect of a symptom management ( SM ) telehealth intervention on physical activity and functioning and to describe the health care use of older adult patients ( aged > 65 years ) after coronary artery bypass surgery ( CABS ) by group ( SM intervention group and usual care group ) . METHODS A r and omized clinical trial design was used . The study was conducted in 4 Midwestern tertiary hospitals . The 6-week SM telehealth intervention was delivered by the Health Buddy ( Health Hero Network , Palo Alto , CA ) . Measures included Modified  7-Day Activity Interview , RT3 accelerometer  ( Stayhealthy , Inc , Monrovia , CA ) , physical activity and exercise diary , Medical Outcomes Study Short-Form 36 , and subjects ' self-report and provider records of health care use . Follow-up times were 3 and 6 weeks and 3 and 6 months after CABS . RESULTS Subjects ( N = 232 ) had a mean age of 71.2 ( + 4.7 ) years . There were no significant interactions using repeated- measures analyses of covariance . There was a significant group effect for average kilocalories/kilogram/day of estimated energy expenditure as measured by the RT3 accelerometer , with the usual care group having a higher estimated energy expenditure . Both groups had significant improvements over time for role-physical , vitality , and mental functioning . Both groups had similar health care use . CONCLUSION Subjects were able to return to preoperative levels of functioning between 3 and 6 months after CABS and to increase their physical activity over reported preoperative levels of activity . Further study of those patients undergoing CABS who could derive the most benefit from the SM intervention is warranted
