Unification of the revised trauma score

Area of Science:

• Trauma research
• Clinical outcomes
• Medical scoring systems

Background:

• The Major Outcome Trauma Study weights-Revised Trauma Score (MTOS-RTS) is the standard for trauma severity assessment.
• It is often confused with the Triage-Revised Trauma Score (T-RTS), used for clinical triage.

Purpose of the Study:

• To compare the predictive accuracy of MTOS-RTS, population-derived RTS (POP-RTS), and T-RTS for trauma mortality.
• Evaluate discrimination and model fit across different trauma populations.

Main Methods:

• Analysis of 22,388 trauma patients from three Level I trauma centers.
• Logistic regression models used to assess discrimination (AUC) and model fit (AIC).

Main Results:

• All three scores (MTOS-RTS, POP-RTS, T-RTS) showed identical discrimination (AUC = 0.841).
• T-RTS and POP-RTS exhibited slightly better model fit than MTOS-RTS.
• T-RTS performed equivalently to MTOS-RTS across all patient groups and centers.

Conclusions:

• The Triage-Revised Trauma Score (T-RTS) can replace the MTOS-RTS for trauma outcome prediction.
• T-RTS offers easier calculation, combined triage/prediction utility, and broad applicability.
