Impact of a home communication intervention for coronary artery bypass graft patients with ischemic heart failure on self-efficacy, coronary disease risk factor modification, and functioning.
OBJECTIVE The purpose of this study is to determine the impact of a home communication intervention ( HCI ) for ischemic heart failure Coronary Artery Bypass Graft ( CABG ) patients > /= 65 years of age on self-efficacy , coronary artery disease risk factor modification and functioning posthospitalization . DESIGN A r and omized clinical trial with repeated measures was used . SAMPLE A sub sample of ischemic heart failure CABG surgery patients ( n = 35 ) was drawn from the parent study of 180 CABG patients . RESULTS HCI participants ( n = 18 ) had significantly higher adjusted mean self-efficacy scores [ F(1 , 29 ) = 6.40 , P < .05 ] and adjusted mean levels of functioning ( physical , general health , mental , and vitality functioning ) compared with the routine care group ( n = 17 ) , using repeated measures analysis of covariance with baseline scores as covariates . There were also significant effects of time on bodily pain and role emotional functioning . Significantly higher exercise adherence ( t = 3.09 , P < .01 ) and lower reported stress ( t = 3.77 , P < .01 ) at 3 months after surgery was reported by HCI subjects . CONCLUSIONS Data from this pilot study can be used to strengthen the HCI intervention with more tailored strategies for vulnerable subgroups of CABG patients
