Abstract

Background and Objectives: Traumatic injuries have become a health problem worldwide, especially in low- to middle-income countries. Therefore, this study was conducted to identify predicting factors of death in adult severe multiple trauma patients. Methods: This retrospective cross-sectional study was performed on 1397 adult multiple trauma patients referred to the emergency department (ED) of Poursina Hospital between June 2019 and August 2021. The demographic characteristics, on admission clinical parameters, laboratory tests, the need for packed red blood cell transfusion, and the need for endotracheal intubation were recorded. The revised trauma score (RTS) was calculated according to the physiological variables collected on admission to ED. The primary outcome was 1-day mortality after admission. Results: The mean age of subjects was 37.12 ± 13.61 (18–60) years, and 1250 (89.5%) subjects were male. The 1-day mortality was 339 patients (24.3%). Initial RTS score and the mean Glasgow coma scale (GCS) scores were significantly higher in the survived group than in the nonsurvived group (6.6 ± 1.2 vs. 4.9 ± 1.0, 10.2 ± 3.7 vs. 4.9 ± 2.4, P < 0.001). The multivariate analysis resulted in low GCS (odds ratio [OR] = 1.527, 95%CI 1.434–1625, P < 0.001), low O2 saturation (OR = 1.023, 95%CI 1.003–1.043, P = 0.022), and need for intubation in the ED (OR = 0.696, 95%CI 0.488–0.993, P = 0.046) as predictors of 1-day mortality. The area under the curves receiver operating characteristics of RTS and GCS scores to predict mortality were 0.853 (95% CI: 0.831–0.874) and 0.866 (95% CI: 0.846–0.887), respectively. Conclusion: Multiple factors associated with 1-day mortality were reduced GCS score, decreased oxygen saturation, and need for intubation in the ED. The RTS and GCS scores are good predictors of mortality survival in multiple trauma patients.
