mortality prediction of mgap scoring system (type of injury, gcs, age, and systolic blood pressure) in trauma patients

introduction trauma is the most common cause of death in people aged 1–44 years and the third leading cause of death regardless of age. early diagnosis can shorten the time of emergency care and a quick transfer of patients to a treatment center. objective this study evaluates the mgap scoring system to predict mortality in trauma patients. materials and methods in this cross-sectional study, 5,484 victims over 12 years old who had referred to a trauma referral hospital were evaluated. an mgap score was assessed based on type of injury, glasgow coma scale (gcs), systolic blood pressure (bp), and patient age. the area under the receiver operating characteristic curve (auroc) was used as a measure of predictive performance. data were analyzed by using spss (ver 16). results patients were divided into three groups as follows: up to 18; 18–22, and greater than 22 scores; in which the mortality rate was 75.2%, 9.5%, and 0.1%, respectively (p < 0.0001).the best cut-off point was 22 for our study in which the mgap scoring system had 93.7% sensitivity and 91.3% specificity. conclusion the mgap scoring system can be used as an appropriate scoring system to triage trauma patients.
