OBJECT: The objective of this study was to identify specific independent risk factors for surgical site infections (SSIs) occurring after laminectomy or spinal fusion. METHODS: The authors performed a retrospective case-control study of data obtained in @entity1 between 1996 and 1999 who had undergone laminectomy and/or spinal fusion. Forty-one @entity1 with SSI or @entity693 were identified, and data were compared with those acquired in 178 uninfected control @entity1 . Risk factors for SSI were determined using univariate analyses and multivariate logistic regression. The spinal surgery-related SSI rate (incisional and organ space) during the 4-year study period was 2.8%. Independent risk factors for SSI identified by multivariate analysis were @entity86 (odds ratio [OR] 8.2, 95% confidence interval [CI] 2.9-22.8), posterior approach (OR 8.2, 95% CI 2-33.5), procedure for @entity5 resection (OR 6.2, 95% CI 1.7-22.3), and @entity5845 (OR 5.2, 95% CI 1.9-14.2). In @entity1 with SSI the postoperative hospital length of stay was significantly longer than that in uninfected @entity1 (median 6 and 3 days, respectively; p < 0.001) and were readmitted to the hospital for a median additional 6 days for treatment of their @entity281 . Repeated surgery due to the @entity281 was required in the majority (73%) of infected @entity1 . CONCLUSIONS: @entity86 , posterior approach, surgery for @entity5 resection, and @entity5845 were independent risk factors predictive of SSI following spinal surgery. Interventions to reduce the risk for these potentially devastating infections need to be developed.
