The study aimed to identify independent prognostic factors for reoperation after surgery for a spinal epidural abscess. Six novel independent prognostic factors were identified through the analysis of two datasets, and multivariate analysis showed a fair predictive ability for reoperation.
BACKGROUND CONTEXT: Spinal epidural abscess is a rare but severe condition with high rates of postoperative adverse events.PURPOSE: The objective of the study was to identify independent prognostic factors for reoperation using two datasets: an institutional and national database.PATIENT SAMPLE: Database 1: Review of five medical centers from 1993 to 2016. Database 2: The National Surgical Quality Improvement Program (NSQIP) was queried between 2012 and 2016.OUTCOME MEASURES: Thirty-day and ninety-day reoperation rate. METHODS: Two independent datasets were reviewed to identify patients with spinal epidural abscesses undergoing spinal surgery. Multivariate analyses were used to determine independent prognostic factors for reoperation while including factors identified in bivariate analyses.RESULTS: Overall, 642 patients underwent surgery for a spinal epidural abscess in the institutional cohort, with a 90-day unplanned reoperation rate of 19.9%. In the NSQIP database, 951 patients were identified with a 30-day unplanned reoperation rate of 12.3%. On multivariate analysis in the NSQIP database, cervical spine abscess was the only factor that reached significance for 30-day reoperation (OR=1.71, 95% CI=1.11-2.63, p=.02, Area under the curve (AUC)=0.61). On multivariate analysis in the institutional cohort, independent prognostic factors for 30-day reoperation were: preoperative urinary incontinence, ventral location of abscess relative to thecal sac, cerreoperation rate also found hypoalbuminemia as a significant predictor (AUC=0.66).CONCLUSION: Six novel independent prognostic factors were identified for 90-day reoperation after surgery for a spinal epidural abscess. The multivariable analysis fairly predicts reoperation, indicating that there may be additional factors that need to be uncovered in future studies. The risk factors delineated in this study through the use of two large cohorts of spinal epidural abscess patients can be used to improve preoperative risk stratification and patient management.
