Impact of a telehealth intervention to augment home health care on functional and recovery outcomes of elderly patients undergoing coronary artery bypass grafting.
OBJECTIVE This pilot study examined the effect of a home communication intervention ( HCI ) to augment home health care ( HHC ) on functioning and recovery outcomes of elderly patients undergoing coronary artery bypass graft . DESIGN A r and omized , experimental two-group ( N = 50 ) repeated- measures design was used . Both HCI and control subjects received HHC , and the HCI group also received the 12-week HCI delivered by a telehealth device , the Health Buddy ( Health Hero Network ) . The Medical Outcome Study Short Form-36 measured physiologic and psychosocial functioning at baseline , 6 weeks , and 3 months after surgery . Follow-up subject interviews ascertained self-report of postoperative problems and health care use . SAMPLE Subjects had an average age of 75.3 years and included males ( 56 % ) and females ( 44 % ) . RESULTS By using repeated- measures analyses of covariance , covariating for the total number of HHC visits , HCI subjects , compared with the HHC group only , had a significantly higher adjusted mean general health functioning score ( F = 8.41 [ 1 , 36 ] , P < .01 ) . There were significant time effects on physical , role-physical , and mental health functioning , indicating that both groups improved over time . The groups reported similar postoperative problems ; however , the control group had more emergency department visits than the HCI group . CONCLUSIONS Findings demonstrate the potential benefit of using an HCI to further augment outcomes of high-risk patients undergoing coronary artery bypass graft surgery referred to HHC after hospitalization
