All consecutive eligible adults physically admitted to the participating ICU during the fixed eight-year clinical window will be screened. Predictor values will be taken from the earliest qualified assessment after injury and before sedation, neuromuscular blockade, and tracheal intubation. The study therefore evaluates prognosis among trauma patients who reached intensive care and does not claim validation for triage of all emergency-department trauma patients.\n\nThe primary endpoint is death from any cause before live discharge from the continuous index admission to the study hospital. The primary comparison will use one common complete-case cohort with known outcome, age, mechanism, qualified Glasgow Coma Scale, systolic blood pressure, and peripheral oxygen saturation. Missing predictor values will not be imputed and will not change cohort eligibility; missingness and the flow from screened to eligible and analyzable participants will be reported.\n\nScore discrimination will be summarized by area under the receiver operating characteristic curve with 95% confidence intervals and paired comparisons using DeLong's method. Observed mortality will be described within original score risk groups. Separate one-predictor logistic models will estimate local score-to-risk relationships, with 1,000 bootstrap resamples for internal validation.

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.
