Abstract
Background: The current study aimed to successively assess the applicability of trauma scoring systems.Objectives: To evaluate the outcomes, prognosis, and mortality in trauma patients.Methods: The present study was conducted on all 221 injured patients referred to Shahid Rajaee Hospital from January 2014 toDecember 2020 with International Classification of Diseases-10th Revision (ICD-10) injury mechanism codes of W32.0-34.09, indicating afirearm injury. Univariate analysis and Chi-square test were employed to discover the individual relationship between each variable andthe injury outcome. Logistic regression analysis was performed to control the confounder. Finally, the area under the Receiver OperatingCharacteristic (ROC) curve was used to compare the predictive efficiency of the injury severity scales.Results: The mortality rate of the gunshot was 15 (6.78%). The cause of the gunshot was related to assaults in 73.68% of the survivingpatients. Meanwhile, suicide attempt was the second cause of death in gunshot patients (16.67%). Most of the injuries that occurredamong 20-24-year-old patients resulted from assaults. The odds of mortality in gunshot victims increased by 4.25 times (95% CI [1.99,9.10]) for each additional unit AIS. In the random forest model, the Trauma Injury Severity Score (TRISS) was the most importantmortality predictor. The TRISS was the highest area under the ROC curve for death prediction among firearms gunshot patients.Conclusion: Injury Severity Score (ISS) had the least, and TRISS had the most area under the curve. Therefore, TRISS was found to be thebest predictor in determining the death or survival of firearms gunshot patients.
