Multiple trauma remains a significant contributor to morbidity and mortality within emergency departments, necessitating rapid and precise initial assessments to prioritize treatment and predict patient prognosis effectively. This study evaluates the prognostic validity of the New Trauma Score (NTS) compared to the Revised Trauma Score (RTS) in predicting in-hospital mortality among multiple trauma patients at Prof. Dr. I.G.N.G. Ngoerah General Hospital. A single-center, retrospective cohort study was conducted involving a total of 61 multiple trauma patients selected via consecutive sampling rom patients admitted between January and December 2022. Statistical analyses were performed to determine the Area Under the Curve (AUC) of the Receiver Operating Characteristic for both scoring systems. Validity parameters encompassed sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and overall diagnostic accuracy. The optimal cut-off thresholds were established at 6.285 for the RTS and 15.5 for the NTS. Both the NTS and RTS demonstrated significant predictive performance regarding mortality in multiple trauma cases. The AUC was calculated at 0.885 for the NTS and 0.865 for the RTS, indicating robust discriminative capabilities for both metrics. While both scoring systems exhibited equivalent sensitivity, the NTS consistently outperformed the RTS in terms of specificity, PPV, NPV, and overall accuracy. These findings indicate that the NTS serves as a superior prognostic tool for predicting mortality among multiple trauma patients compared to the RTS. Furthermore, this study underscores the critical importance of local validation for trauma scoring systems and highlights the potential clinical utility of the NTS in optimizing emergency decision-making.
