Timely angioembolization (AE) is known to improve outcomes of patients with hemorrhage resulting from pelvic fracture. The hybrid emergency room system (HERS) is a novel trauma resuscitation room equipped with a computed tomography scanner, fluoroscopy equipment, and an operating room setup. We hypothesized that the HERS would improve the timeliness of AE for pelvic fracture. A retrospective medical record review of patients who underwent AE for pelvic fracture at our institution from April 2015 to December 2018 was conducted. Patients' demographics, location of AE, Injury Severity Score, Revised Trauma Score, probability of survival by the trauma and injury severity score (TRISS Ps) method, presence of interventional radiologists (IRs) upon patient arrival, time from arrival to AE, and in-hospital mortality were analyzed. These data were compared between patients who underwent AE in the HERS (HERS group) and in the regular angio suite (non-HERS group). Ninety-six patients met the inclusion criteria. The HERS group comprised 24 patients, and the non-HERS group, 72 patients. Interventional radiologists were more frequently present upon patient arrival in the HERS than non-HERS group (IRs, 79% vs. 22%, p < 0.01). The time from arrival to AE was shorter in the HERS than non-HERS group (median [range], 46 [5-75] minutes vs. 103 [2-690] minutes, p < 0.01). There were no differences in the rate of in-hospital mortality (13% vs. 15%, p = 0.52) between the two groups. Survivors in the HERS group had a lower probability of survival by the trauma and injury severity score (median [range], 61% [1%-98%] vs. 93% [1%-99%], p < 0.01) than survivors in the non-HERS group. The HERS improved the timeliness of AE for pelvic fracture. More severely injured patients were able to survive in the HERS. The new team building involving the addition of IRs to the traditional trauma resuscitation team will enhance the benefit of the HERS. Therapeutic, level IV.
