The objectives of this pilot trial were to test the feasibility of all procedures, specifically to determine: 1) an estimate of patient and peer recruitment rates, 2) peer compliance and dose of the intervention, 3) peer satisfaction with orientation, 4) peer support activities offered to patients, and 5) patients' satisfaction with peer support. Additionally, exploratory research questions were used to determine indicators of the effects of peer support on HRQOL, pain, pain-related interference with activities, function, depressive symptoms, and enrolment in cardiac rehabilitation. An 8-week pre-post test RCT design enrolled men and women undergoing CABG surgery at a single site in Southeastern Ontario. Patients were randomized to either a usual care or an intervention group. Patients allocated to usual care received preoperative/postoperative education sessions, a preoperative video/information booklet, and preoperative/postoperative visits from in-hospital peer volunteers. In addition to usual care, patients in the intervention group received individualized education and support via telephone for 8 weeks following hospital discharge from trained peer volunteers.
