Abstract	Background A hybrid emergency room (ER) is defined as an emergency unit with four functions—performing resuscitation, computed tomography (CT), surgery, and angiography. However, the safety and efficacy of performing CT in a hybrid ER are unclear in primary surveys. Therefore, this study aimed to evaluate the safety and clinical effects of hybrid ERs. Methods This retrospective observational study used data from the Shimane University Hospital Trauma Database from January 2016 to February 2019. Hospitalized patients with severe trauma and an injury severity score of ≥ 16 were divided into the non-hybrid ER group (n = 134) and the hybrid ER group (n = 145). The time from arrival to CT and interventions and the number of in-hospital survivors, preventable trauma deaths (PTD), and unexpected survivors (US) were assessed in both groups. Further, the amount of blood transfused was compared between the groups using propensity score matching. Results The time from arrival to CT and interventions was significantly reduced in the hybrid ER group compared to that in the non-hybrid ER group (25 vs. 6 min; p < 0.0001 and 101 vs. 41 min; p = 0.0007, respectively). There was no significant difference in the rate of in-hospital survivors (96.9% vs. 96.3%; p = 0.770), PTD (0% vs. 0%), and US (9.0 vs. 6.2%; p = 0.497) between the groups. The amount of blood transfused was significantly lower in the hybrid ER group than in the non-hybrid ER group (whole blood 14 vs. 8, p = 0.004; red blood cell 6 vs. 2, p = 0.012; fresh frozen plasma 9 vs. 6, p = 0.021). This difference was maintained after propensity score matching (whole blood 28 [10–54] vs. 6 [4–16.5], p = 0.015; RBC 8 [2.75–26.5] vs. 2 [0–8.5], p = 0.020, 18 [5.5–27] vs. 6 [3.5–7.5], p = 0.057). Conclusions The study results suggest that trauma treatment in a hybrid ER is as safe as conventional treatment performed in a non-hybrid ER. Further, hybrid ERs, which can reduce the time for trauma surveys and treatment, do not require patient transfer and can reduce the amount of blood transfused during resuscitation.
