Comparison of the predictive performance of the BIG TRISS and PS09 score in anadult trauma population derived from multiple international trauma registries

摘要

BackgroundThe BIG score (Admission base deficit (B), International normalized ratio (I), and Glasgow Coma Scale (G)) has been shown to predict mortality on admission in pediatric trauma patients. The objective of this study was to assess its performance in predicting mortality in an adult trauma population, and to compare it with the existing Trauma and Injury Severity Score (TRISS) and probability of survival (PS09) score.
