BACKGROUND : Elderly patients with Traumatic Brain Injury (TBI) are frequently transferred to designated Trauma Centers (TC). We hypothesized that TC transfer is associated with improved outcomes. METHODS : Retrospective study utilizing the National Trauma Databank. Demographics, injury and outcomes data were abstracted. Patients were dichotomized by transfer to a designated level I/II TC vs. not. Multivariate regression was used to derive the adjusted primary outcome, mortality, and secondary outcomes, complications and discharge disposition. RESULTS : 19,664 patients were included, with a mean age of 78.1 years. 70% were transferred to a level I/II TC. Transferred patients had a higher ISS (12 vs. 10, p < 0.001). Mortality was significantly lower in patients transferred to level I/II TCs (5.6% vs. 6.2%, Adjusted Odds Ratio (AOR) 0.84, p = 0.011), as was the likelihood of discharge to skilled nursing facilities (26.4% vs. 30.2%, AOR 0.80, p < 0.001). CONCLUSIONS : Elderly patients with mild TBI transferred to level I/II TCs have improved outcomes. Which patients with mild TBI require level I/II TC care should be examined prospectively.
