BackgroundThe effect of regionalized trauma care (RT) on hospital-based outcomes for traumatic spine injury (TSI) in the United States is unknown.ObjectiveTo test the hypothesis that RT would be associated with earlier time to surgery and decreased length of stay (LOS).MethodsTSI patients >14 yr were identified using International Classification of Diseases Ninth Revision Clinical Modification diagnostic codes. Data from 2008 through 2012 were analyzed before and after RT in 2010.ResultsA total of 4072 patients were identified; 1904 (47%) pre-RT and 2168 (53%) post-RT. Injury severity scores, Spine Abbreviated Injury Scale scores, and the percentage of TSIs with spinal cord injury (tSCI) were similar between time periods. Post-RT TSIs demonstrated a lower median intensive care unit (ICU) LOS (0 vs 1 d; P < 0.0001), underwent spine surgery more frequently (13% vs 11%; P = 0.01), and had a higher rate of spine surgery performed within 24 h of admission (65% vs 55%; P = 0.02). In patients with tSCI post-RT, ICU LOS was decreased (1 vs 2 d; P < 0.0001) and ventilator days were reduced (average days: 2 vs 3; P = 0.006). The post-RT time period was an independent predictor for spine surgery performed in less than 24 h for all TSIs (odds ratio [OR] 1.52, 95% confidence interval [CI]: 1.04-2.22, C-stat = 0.65). Multivariate linear regression analysis demonstrated an independent effect on reduced ICU LOS post-RT for TSIs (OR -1.68; 95% CI: -2.98 to 0.39; R2 = 0.74) and tSCIs (OR -2.42, 95% CI: -3.99-0.85; R2 = 0.72).ConclusionRT is associated with increased surgical rates, earlier time to surgery, and decreased ICU LOS for patients with TSI.Copyright © 2018 by the Congress of Neurological Surgeons.
