Abstract

Depression following cardiac surgery has been reported in older adults; however, the evidence to date does not clearly specify the onset of depression and its relationship to cardiac surgery. The purpose of this descriptive, correlational study was to examine the association between preoperative depression and selected postoperative outcomes in older adults following CABG surgery. The five selected postoperative outcomes were 30 day readmission rate, hospital length of stay, intensive care unit length of stay, ventilator time, and 30 day mortality. A sample size of 87 older adult cardiovascular surgery patients was selected for this study. Thirteen (14.9%) of the participants had preoperative depression in. There were no significant relationships between preoperative depression and the postoperative outcomes of ICU length of stay, ventilator time, hospital length of stay, 30-day readmission, and 30-day mortality in older adults in this study who underwent CABG. Multiple studies have been conducted with results that indicate postoperative depression is associated with poorer postoperative outcomes. It remains unclear if preoperative depression is associated with postoperative outcomes in this population. The gap in knowledge related to the presence of depression preoperatively and postoperative outcomes needs further exploration.
