| Trauma is one of the major health problems worldwide. There are several indicators for predicting trauma mortality in the world, some of them are physiological, some anatomical, and some others are both psychological and anatomical. Our aim in this study was to compare the predictive power of GAP versus PHI in predicting mortality from trauma. Methods: This prospective study was performed using data from Imam Reza Hospital in Tabriz, HaftTir and Sina Hospital, in Tehran, during 2020 and 2021. Descriptive results were reported with mean, standard deviation, absolute frequency and absolute frequency percentage. Simple logistic regression, multiple logistic regression and receiver operating characteristic (ROC) were used to evaluate the predictive power of the studied indices. All analyses were performed at a significance level of 0.05. Results: A total of 540 trauma patients participated in this study. The mean and standard deviation
of the age of the patients participating in this study was 34.71± 17.65. The majority of the patients (81.67%) were male. Finally, until the 30th day of follow-up, 62 patients (11.48 %) died. Glasgow coma scale (GCS), pulse rate,
age, respiratory status and level of consciousness significantly predict trauma mortality (P-value < 0.00). The area under roc curve (AUC) value was 0.926 for PHI and 0.920 for GAP. Conclusion: GAP is a more appropriate index than
PHI to predict trauma deaths and triage of trauma patients in the emergency
room. We recommend that the use of GAP be prioritized over PHI for triaging
patients in the emergency room. |
