Thorax trauma severity score and trauma injury severity score evaluation as outcome predictors in chest trauma

Abstract

Objective The aim was to evaluate the performance of thorax trauma severity score (TTSS) in predicting hospital mortality in thoracic trauma and comparing its performance with the trauma and injury severity score (TRISS).Background Because the great risk of thoracic trauma that may be life-threatening especially if uncontrolled, early management of it reduces mortality of polytraumatized patients. TTSS and TRISS were developed for the purpose of prediction of hospital mortality in thoracic trauma.Patients and methods This is a prospective comparative study done on 100 patients with chest trauma, either isolated chest trauma or as a part of polytrauma, who presented to the Emergency Department of Menoufia University Hospital during the period from April 2019 to April 2020. TTSS score was applied to assess its performance and comparing it with TRISS score.Results TTSS and TRISS scores were applied on 100 patients with trauma meeting inclusion criteria to predict the hospital mortality in thoracic trauma. The area under the receiver operating characteristics curve was 0.88 for TTSS score and 0.892 for TRISS score.Conclusion This study demonstrates that the TRISS, and the TTSS, can be used to predict hospital mortality in patients with thoracic trauma; hence, additional prospective studies are required. We believe that the study provides important information regarding validation of the TTSS, as it had a direct correlation with need for oxygenation, ventilator, duration of hospital stay, mortality, or outcome in patients with chest trauma.
