DOWNLOAD EBOOKThe purpose of this randomized clinical trial was to evaluate the effectiveness of a weekly individualized, telephone, educational intervention for coronary artery bypass graft (CABG) surgical patients during the first three weeks following discharge from hospital. Orem's Theory of Self-Care guided the design of the intervention and the study. An experimental design with repeated measures was used to determine the effectiveness of the intervention on improving knowledge of symptom management and performance of therapeutic self-care behaviours, and in reducing symptom severity. Patients (N=88), undergoing their first CABG surgery, were randomly assigned to one of two groups either receiving the usual pre-discharge education or the usual predischarge education and the individualized, telephone intervention. The three educational intervention sessions focused on patients' concerns related to six post-operative symptoms (ie. pain, anxiety, depression, fatigue, sleep disturbances, and activity limitations) and related symptom management strategies were discussed. Data related to symptom severity were collected at pre-test (during hospitalization) and during each of the three weeks of the intervention implementation. Data related to knowledge of symptom management and therapeutic self-care were collected at pre-test and at post-test (week 4). Major findings from the analyses indicated that the intervention was effective in improving knowledge of symptom management and performance of therapeutic self-care behaviours, and in reducing symptom severity. Anxiety, fatigue, sleep disturbances, and activity limitations were significantly decreased in the intervention group during each of the first three weeks following discharge as compared to the control group. Pain intensity and interference, as well as depression were lower in the intervention group at weeks 2 and 3 after discharge. Moderate positive correlations were found between knowledge of symptom management and therapeutic self-care, knowledge of symptom management and the symptoms severity of pain interference, fatigue, and activity limitations, as well as with therapeutic self-care and the severity of all symptoms except for pain intensity. Age was negatively moderately correlated with knowledge of symptom management. Some of the implications from the study findings are related to examining the long-term effectiveness of the intervention and evaluating the feasibility of implementing the intervention in a hospital-based setting.
