Abstract 16284: Patients' Perception of Postoperative Quality of Life Depends on Preoperative Health State
OBJECTIVES Health-related quality of life (QOL) is a critical determinant of patient satisfaction and post-operative success. This study prospectively examines the effect of cardiac surgery procedures on patient perceptions of QOL before and after the operation, and identifies what components of physical and mental functioning are most significantly impacted.
METHODS From September 2010 to March 2011, all elective cardiac surgery patients were given a QOL survey (Short-Form 12, version 2) to complete preoperatively and postoperatively. Both surveys were completed by 127 patients. Survey data were prospectively gathered; intraoperative data and postoperative outcomes were retrospectively reviewed. Primary QOL outcomes were the physical (PCS) and mental (MCS) component summary measures of the SF-12 survey, as well as eight individual component scores. Other outcomes of interest included postoperative morbidity and mortality. Statistical analysis was performed using student t-test, chi-square test, Fisher's exact test, and multivariate linear regression.
RESULTS The mean age of the study group was 67 ± 14 years. Of the 127 patients who completed both surveys, 109 had a median sternotomy and 18 had minimally invasive cardiac surgery (MICS). Pre-op PCS and MCS scores were positively correlated with post-op scores (p < 0.001, see figure). Overall, post-op PCS was significantly lower than pre-op PCS (-3.17 ± 1.18, p = 0.008), except in patients with pre-op congestive heart failure (CHF), in which there was a significant improvement in PCS (7.80 ± 2.49, p = 0.002). Post-op respiratory failure was correlated with worse PCS (p=0.045) and post-op stroke was correlated with worse MCS (p=0.009).
CONCLUSIONS Self-reported quality of life measures after cardiac surgery are dependent on pre-operative perception of health. Patients with symptomatic CHF before surgery had the greatest improvement in perceived QOL post-operatively.
