Background: Trauma center and multidisciplinary management protocols have been proven to improve the outcomes of severely injured patients. Hemorrhage from pelvic injury is associated with high mortality and is a common cause of preventable trauma death. This study aimed to evaluate the effects of the establishment of a trauma center and management protocols on the outcomes of hemodynamically unstable patients with pelvic fractures. Methods: Hemodynamically unstable patients with pelvic fractures were reviewed retrospectively over a 10-year period. They were grouped into the pre-phase and post-phase, which were defined as before and after the establishment of a trauma center and protocols, respectively. Basic characteristics and outcomes were compared between periods. Results: This study enrolled a total of 106 patients. Basic and physiological characteristics were not significantly different in both phases. Pre-peritoneal packing and resuscitative endovascular balloon occlusion of aorta were only performed in the post-phase (pre-peritoneal packing, N = 27; resuscitative endovascular balloon occlusion of aorta, N = 10). In the post-phase, the time from emergency department arrival to hemostatic intervention was significantly shorter (269 ± 132.4 min vs 147.2 ± 95.5 min, p < 0.0001), and mortality due to acute hemorrhage was significantly lower (p = 0.003; absolute risk reduction: 0.22; relative risk reduction: 0.72). Multivariate logistic regression analysis identified age, injury severity score, and the pre-phase as independent risk factors for mortality. Conclusion: The establishment of a trauma center and multidisciplinary management protocols, such as pre-peritoneal packing and resuscitative endovascular balloon occlusion of aorta, improved the outcomes of hemodynamically unstable patients with pelvic fractures.
