Mechanism of Injury, Glasgow Coma Scale, Age, and Systolic Blood Pressure: A New Trauma Scoring System to Predict Mortality in Trauma Patients

Background: Trauma is the most common cause of death in people aged ۱ - ۴۴ years and the third leading cause of death regardless of age. Early diagnosis can expedite emergency care and thus patients can be transferred more quickly to a treatment center. Objectives: The purpose of this study was to evaluate the mechanism of injury, Glasgow coma scale, age, and arterial pressure (MGAP) scoring system in predicting mortality in trauma patients. Patients and Methods: In this cross-sectional study, ۵,۴۸۴ victims over ۱۲ years of age referred to a trauma referral hospital and were evaluated. The MGAP score was assessed based on type of injury, Glasgow coma scale (GCS), systolic blood pressure (BP) and patient’s age. The area under the receiver operating characteristic (AUROC) curve was used as a measure of predictive performance. Data were analyzed using SPSS software version ۱۶. Results: Patients were divided into three groups : scores of less than ۱۸, ۱۸ - ۲۲ and greater than ۲۲; in which the mortality rates were ۷۵.۲%, ۹.۵% and ۰.۱%, respectively (P < ۰.۰۰۰۱). The best cut-off point was ۲۲ in our study, and the MGAP scoring system had ۹۳.۷% sensitivity and ۹۱.۳% specificity. Conclusions: The MGAP scoring system can be used as an appropriate scoring system to predict mortality in triage trauma patients
