Correlation Between Shock Index, TRISS, MGAP, NTS, MESS, and MEWS for Prediction of Outcome in Patients with Multiple Trauma

Introduction: In trauma patients, various severity scoring indices have been developed to predict the severity of injury and mortality. This study aimed to investigate the relationship between severity scoring indices for predicting survival in moderate and severe trauma patients.Methods: This cross-sectional study was conducted among ۱۰۰ trauma patients. Information on each of the Shock Index, Glasgow Coma Scale/Age/Pressure (GAP), RGAP, New Trauma Score (NTS), Mechanism/Glasgow Coma Scale/Age/Pressure (MGAP), Modified Early Warning Score (MEWS), and Trauma and Injury Severity Score (TRISS) indices was separately completed for moderate and severe trauma patients. Statistical analyses were performed using SPSS version ۲۱.Results: In this study, no significant differences were observed between surviving and deceased patients in terms of the Shock Index, GAP, RGAP, NTS, MGAP, MEWS, and TRISS indices. However, in all these indices, significant differences were observed between multi-trauma patients with and without morbidity. According to the ROC curve, a value less than ۹۲.۵% for the SPO۲ variable was the best cutoff point for predicting the probability of death in multi-trauma patients. Also, ROC curves showed that a value higher than ۹۵.۵% for SPO۲, a GCS score less than ۷.۵, an RR value less than ۱۹.۵, a GAP score less than ۱۴.۵, an RGAP score less than ۱۳.۵, an MGAP score less than ۱۸, a TRISS score less than ۵۴.۲, an MEWS score higher than ۳.۵, and an NTS score less than ۱۴.۵ were the best ways to tell if a patient with multiple injuries was likely to be hospitalized.Conclusion: The GAP, RGAP, MGAP, NTS, and TRISS scoring systems performed well in predicting morbidity in multi-trauma patients. However, according to the ROC curve, the GAP and RGAP indices performed slightly better than other indices. The findings of this study can be useful in better assessing survival rates, mortality, and timely treatment and intervention in trauma patients.
