Coronary artery bypass (CAB) surgery patients experience profound declines in physical, psychological, and relational health-related quality of life (HRQOL) following surgery. The purpose of this study was to examine HRQOL outcomes in CAB surgery patients and partners enrolled in either the innovative Partners Together in Health (PaTH) intervention or usual care cardiac rehabilitation (CR). An experimental, two-group, repeated measures design was used to examine patients and partners randomly assigned to the groups. Instruments used to measure HRQOL were: the SF-36 Physical Functioning subscale, the Patient Health Questionnaire (PHQ-9) for depression, and the Dyadic Adjustment Scale for marital quality. Thirty-four couples were recruited for the primary study. HRQOL data were collected close to the start of CR (T1), the end of CR (T2), and 3 months after CR (T3). Data were analyzed using Wilcoxon signed rank tests for changes over time; and Mann Whitney U test were used to examine group differences. Findings indicated that physical functioning was lowest for patients at baseline and improved over time. Partners' physical functioning was relatively high and remained stable. Partners in the PaTH group significantly improved physical function between T1 and T2. Patients in both groups significantly improved their depression scores between T1 and T2: 18% of patients and 12% of partners were depressed at T1. Marital adjustment scores indicated that both patients and partners were in the maritally adjusted category. However, about 12% of patients and partners rated themselves as maritally distressed at T1; and increased to almost 15% at T2 and T3 for partners. Overall, there was no evidence of differences on any of the HRQOL variables between patients, or between partners, in the PaTH or usual care groups. There was a trend toward greater improvement in patients' submaximal exercise performance during CR in the PaTH group compared the usual care group (55% vs. 43%). This study adds to our understanding of the trajectory of HRQOL outcomes following CAB surgery for patients and their partners. Because patients and partners are impacted by the CAB surgery as a shared life experience, interventions focusing on the couple are needed to improve their HRQOL outcomes.
