Trauma and injury severity score in predicting mortality of polytrauma patients

TRISS (Trauma and Injury Severity Score) is one of the most commonly used trauma score. Currently, there is no data about using TRISS in the care of polytrauma patients at emergency department of dr. Cipto Mangunkusumo Hospital (CMH). This research was intended to evaluate whether TRISS can predict the mortality of polytrauma patients at CMH. This was an analytic descriptive study with retrospective cohort design. Data was collected from medical records of polytrauma patients who were admitted to emergency department of CMH from 2011-201 4 then we analyzed the relationship between TRISS and patient’s prognosis. Furthermore, we conducted bivariate and multivariate analysis by SPSS 20 software. Seventy medical records were included in this study. The majority of patients were male (65%) in young age. There were 69 patients who experienced blunt trauma, with the majority (94.3%) were caused by motor vehicle accident. After receiving trauma care, there were 26 deaths, while other 44 patients survived. From bivariate and multivariate analysis, we found a significant difference between TRISS and patient’s prognosis. TRISS strongly predicts polytrauma patient’s mortality (AUC 0,899; IK95% 0,824-0,975). TRISS has 84,6% sensitivity and 81.8% specificity with optimal intersection point ≤ 90,5. TRISS is able to predict the mortality of polytrauma patients at CMH.
