Abstract
This study examined the patient perspective of surgical success through the measurement of health-related quality of life (HRQOL), in order to identify the patient characteristics and process issues associated with postoperative changes in health status. Patients completed the RAND 36-item Health Survey 1.0 (SF-36) prior to surgery and at 6 months following surgery. Baseline patient demographic and clinical information were collected from the medical record and were used to develop models of change in HRQOL for 68 patients. While many patients improved, a number experienced no change or even a decline in HRQOL in the postoperative period. Factors associated with change in HRQOL are presented. The findings suggest that factors associated with change in health status can be systematically assessed, which may lead to the development of interventions aimed at those patient characteristics or process issues that impact on HRQOL.
