Randomized trial of a home recovery intervention following coronary artery bypass surgery

For this study a randomized clinical trial was designed to test the effects of an early home recovery information intervention on physical functioning, psychological distress, and symptom frequency 1 month following coronary artery bypass graft surgery (CABG). Recovery outcomes were compared between two groups: those receiving an audiotape of information on expected physical sensations and their management (Cardiac Home Information Program [CHIP]) in addition to the usual care, and those receiving the usual cardiac discharge information protocol. A nonprobability sample of 180 patients (84 women and 96 men; mean age = 62 years) was equally distributed between the two study groups. When controlling for age, comorbidity, and cardiac functional status, the results showed positive effects on physical functioning in women and psychological distress, vigor and fatigue in men. Consistent with other studies, women had worse physical functioning and more symptom frequency than men. These findings indicate that the CHIP intervention is an effective method to prepare CABG patients for home recovery.
