Abstract
Background. There is growing interest in comparing resource, as well as patient outcome metrics among coronary artery bypass graft surgery (CABG) providers, yet few tools exist for adjusting these provider comparisons for patient case-mix. In this study, we aimed to define the magnitude of hospital variability in postoperative length of stay (PLOS) in contemporary practice and to determine the degree to which this variability was accounted for by differences in patient case-mix. We also sought to determine the relationship between hospitals' risk-adjusted PLOS and mortality outcomes. Methods. We analyzed 496,797 isolated CABG procedures performed between January 1997 to January 2001 at 587 US hospitals participating in the Society of Thoracic Surgeon's National Cardiac Database. Logistic and linear regression were used to identify independent preoperative factors affecting a patient's likelihood for early discharge (PLOS
