Revised Trauma Score (RTS) using coded Glasgow Coma Scale, systolic blood pressure, and respiratory rate to triage trauma patients and predict survival.
0.9368 × GCS code + 0.7326 × SBP code + 0.2908 × RR code, where each parameter is coded 0–4 (total range 0–7.8408)
0–7.8408
RTS is a triage tool used in trauma systems. An RTS <4 predicts survival probability <70% and warrants consideration of transfer to a trauma center. Coding: GCS 13–15=4, 9–12=3, 6–8=2, 4–5=1, 3=0; SBP >89=4, 76–89=3, 50–75=2, 1–49=1, 0=0; RR 10–29=4, >29=3, 6–9=2, 1–5=1, 0=0.

0–7.8408
Provides an objective, coded measure of physiologic derangement in trauma patients for triage and outcome prediction.
RTS range 0–7.8408. An RTS below 4 is associated with a predicted survival below 70% and supports transfer to a trauma center. Values at the top of the range indicate minor physiologic derangement.
The Revised Trauma Score is a standard triage instrument in trauma systems worldwide, combining the three most prognostic physiologic parameters into a single weighted score.
A motor-vehicle collision patient has GCS 13, systolic blood pressure 110 mmHg, and respiratory rate 20/min.
Inputs:
RTS 7.8408 — minor physiologic derangement; standard trauma care.
