Several scoring systems have been and continue to be developed in numerous countries with the goal of quickly and accurately assessing the severity of trauma injuries. The aim of this study was to identify factors that help to determine the gravity of damage and to minimize it, in order to reduce mortality and morbidity. It is important that the criteria set for the determination of the severity of trauma are objective, measurable, and comparable. This study was an assessment of the contribution of vital signs, hemogram values, and trauma severity scores recorded at initial admission in the prediction of mortality in patients with firearm trauma wounds.


This was a retrospective cohort study. Patients with gunshot injuries who were admitted to the emergency department (ED) of a single facility between December 2015 and March 2016 were included in the study. Statistical software was used to perform bivariate analyses using a t-test or the Mann-Whitney U test for continuous variables, depending on the distribution of variables, and logistic regression analysis was utilized to determine independent predictors of mortality after ED admission. A p value of <0.05 was considered statistically significant.


A total of 418 patients were included. A statistically significant difference was found between the white blood cell count, respiratory rate, Glasgow Coma Scale score, Abbreviated Injury Scale score, and the Injury Severity Score (ISS) of the patients who survived and those who died (p<0.05). The analysis also indicated that a systolic blood pressure below 90 mmHg and a heart rate above 100 beats/minute were independent variables in terms of the expectation of mortality.


The objective assessment of the ISS at admission to the ED is an important element in the calculation of hemoglobin requirements, mortality, and morbidity.
