Context Health-related quality of life has not been evaluated as a predictor of mortality following coronary artery bypass graft (CABG) surgery.
Evaluation of health status as a mortality predictor may be useful for preoperative risk stratification.
Objective To determine whether the Physical and Mental Component Summary scores from the preoperative Short-Form 36 (SF-36) health status survey predict mortality following CABG surgery after adjustment for known clinical risk variables.
Design Prospective cohort study conducted between September 1992 and December 1996.
Setting Fourteen Veterans Affairs hospitals.
Patients Of the 3956 patients undergoing CABG surgery only and who were enrolled in the Processes, Structures, and Outcomes of Care in Cardiac Surgery study, the 2480 who completed a preoperative SF-36.
Main Outcome Measure All-cause mortality within 180 days after surgery.
Results A total of 117 deaths (4.7%) occurred within 180 days of CABG surgery.
The Physical Component Summary of the preoperative SF-36 was a statistically significant risk factor for 6-month mortality after adjustment for known clinical risk factors for mortality following CABG surgery.
In multivariate analysis, a 10-point lower SF-36 Physical Component Summary score had an odds ratio (OR) of 1.39 (95% confidence interval [CI], 1.11-1.77 ; P=006) for predicting mortality.
The SF-36 Mental Component Summary score was not associated with 6-month mortality in multivariate analyses (OR, 1. (...)
