Background: Authoritative trauma scoring systems can quickly assess the damage and show its severity plus prognosis. The purpose of this study was to investigate the predictive value of the new Glasgow Coma Scale, age, and systolic blood pressure (GAP) and the new trauma score (NTS) indicators to determine the mortality of trauma patients in hospitals in Sirjan in 2019. Materials and Methods: In a descriptive-analytical study, 2570 patients with multitrauma caused by traffic accidents transferred by the prehospital emergency were enrolled in the study. Demographic variables of patients as well as GAP and NTSs were collected and calculated, with the outcome of patients followed up and recorded during hospitalization. The predictive value of these scores was determined in clarifying the outcome of patients using SPSS software. Results: Of the total number of patients studied, 14 (0.5%) patients died during hospitalization. The mean GAP and NTS scores in dead patients were 12.78 ± 6.92 and 11.64 ± 7.36, respectively. Furthermore, in surviving patients, they were 22.19 ± 1.12 and 22.30 ± 1.22, respectively, with a P < 0.05 in each case. Based on the above tools with 95% confidence level, the area under the curve for the mortality was 0.932 for the GAP system and 0.944 for the NTS (P > 0.001). Conclusions: Both indicators could predict the mortality of patients with multitrauma. It could also be used to determine the priority of dispatch at the scene of the accident and the triage of the injured (people). Based on the results of the receiver operating characteristic curve, the NTS score has a higher accuracy
