Study DesignA retrospective cohort analysis of prospectively collected clinical data.ObjectiveThe aim of this study was to assess the effect of race on outcomes in patients undergoing elective laminectomy and/or fusion spine surgery.Summary Of Background DataStudies that have looked at the effect of race on spine surgery outcomes have failed to take into account baseline risk factors that may influence peri-operative outcomes.MethodsWe identified 48,493 adult patients who underwent elective spine surgery consisting of elective laminectomy and/or fusion, from 2006 to 2012, at hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP), a prospectively collected, national clinical database with established reproducibility and validity. Pre- and intraoperative characteristics and 30-day outcomes were stratified by race. We used propensity scores to match African-American and Caucasian patients on all pre- and intraoperative factors, including by principal diagnosis leading to surgery as well as surgery performed. We used regular and conditional logistic regression to predict the effect of race on adverse postoperative outcomes in the full sample and matched sample.ResultsCaucasians comprised 82% of our sample. We found no differences in the incidence of pre- and intraoperative factors when comparing Caucasian patients with all minority patients, and only minimal increased odds for prolonged length of length of hospitalization (LOS) and discharge with continued care. However, African-American patients, who comprised 39% of our minority sample, had more preoperative comorbidities than Caucasian patients. Even after eliminating all differences between pre- and intraoperative factors between Caucasian and African-American patients, African-American patients continued to have LOS that was, on average, one day longer than Caucasian patients. African-American patients also had higher odds for major complications [odds ratio (OR) = 1.3; 95% confidence interval (95% CI) 1.1-1.6], and to be discharged requiring continued care (OR = 2.3; 95% CI 1.8-2.8).ConclusionAfrican-American race is independently associated with prolonged LOS, major complications, and a need to be discharged with continued care in patients undergoing elective spine surgery.Level Of Evidence3.
