Comparing the Predictive Ability for Mortality Rates by GAP and MGAP Scoring Systems in Multiple-Trauma Patients

Background and Trauma scoring systems help physicians and nurses in recognizing the severity of trauma and its management. The purpose of this study was to investigate and compare the predictive ability of mortality rates of two trauma scoring systems (MGAP and GAP) in multiple trauma patients.
In this cross-sectional study, we used the data available in electronic records for trauma patients admitted to Rasht Poorsina Hospital, Iran. Demographic data, and GAP and MGAP (Mechanism, Glasgow Coma Scale, Age, and Pressure) scores for 1541 patients were extracted. Then, the ability of both scores in short-term (24 hours) and long-term (4-week) mortality prediction rates was analyzed using SPSS V21.
The surface areas under the curve ratio of ROC for predicting short-term mortality rates were 0.947 and 0.938, and for long-term mortality rates were 0.928 and 0.914 for GAP and MGAP, respectively (P Both GAP and MGAP could appropriately predict mortality rate without any significant difference. Therefore, these scores could be used as triage tools, and in predicting the severity of injuries and mortality.
