Objective: We aimed to study the factors affecting the mortality of trauma patients who underwent whole-body computerized tomography (CT) on Emergency department (ED) time frames in a developing emergency care system. Materials and Methods: This is a retrospective analysis of adult patients who received WBCT from August to November for two consecutive years (2014 and 2015). Non-parametric statistical methods were used to compare the patients who died and survived. The Backward logistic regression model was used to define factors significantly affecting mortality. Results: During 2014, 200 patients out of 827 (24.1%) received WBCT. During 2015, 263 patients out of 951 (27.6%) received WBCT. Four hundred sixteen patients were entered into the analysis. The overall mortality was 3.4% (7% in 2014 and 1% in 2015, P = 0.002). Significant factors found in backward logistic regression model defining factors affecting mortality were ISS (p < 0.0001), Glasgow Coma Scale (GCS) (p = 0.001). CT location (outside the ED in 2014, inside the ED in 2015) showed a very strong trend for affecting mortality (p = 0.054). Patients who had WBCT in the ED had lower ISS (p < 0.0001). CT imaging in the ED decreased ED to CT time 15.5 minutes (p < 0.0001), but admission time was 75.5 minutes longer. Conclusions: ISS and GCS were the main factors predicting mortality in patients who received WBCT. Patients received more WBCT imaging and physicians showed a tendency to order WBCT for less severe patients when the CT located in the ED. CT location did not show a significant effect on mortality, but on some operational time frames.
