Evaluation of Three Trauma Mortality Scores in Adults Admitted to Intensive Care in Tunisia

The goal of this retrospective observational study is to learn how well three simple trauma scores predict death during the hospital stay in adults admitted to intensive care after an injury in Tunisia. The scores are the Glasgow Coma Scale, Age, and Systolic Blood Pressure score (GAP); the Mechanism, Glasgow Coma Scale, Age, and Systolic Blood Pressure score (MGAP); and the New Trauma Score for Triage (T-NTS). Researchers will review existing medical records for admissions from 1 January 2018 through 31 December 2025. They will not assign treatment or contact participants. The main question is how accurately the three scores distinguish participants who died in the hospital from those discharged alive. Secondary analyses will examine agreement between score-based risk and observed mortality and performance for mortality by day 7 after ICU admission.
