Revised Trauma Score
Purposephysiologic scoring system

The Revised Trauma Score (RTS) is a physiologic scoring system based on the initial vital signs of a patient.[1] A lower score indicates a higher severity of injury.[2]

Use in triage

The Revised Trauma Score is made up of three categories:

systolic blood pressure, and respiratory rate. The score range is 0–12. In START triage, a patient with an RTS score of 12 is labeled delayed, 11 is urgent, and 3–10 is immediate. Those who have an RTS below 3 are declared dead and should not receive certain care because they are highly unlikely to survive without a significant amount of resources.[citation needed

Scoring

The score is as follows:[3]

Glasgow Coma Scale
GCS Points
15–13 4
12–9 3
8–6 2
5–4 1
3 0
Systolic Blood Pressure
SBP Points
>89 4
76–89 3
50–75 2
1–49 1
0 0
Respiratory Rate
RR Points
10-29 4
>29 3
6–9 2
1–5 1
0 0

These three scores (Glasgow Coma Scale, Systolic Blood Pressure, Respiratory Rate) are then used to take the weighted sum by RTS = 0.9368 GCS + 0.7326 SBP + 0.2908 RR. Values for the RTS are in the range 0 to 7.8408. The RTS is heavily weighted towards the Glasgow Coma Scale to compensate for major head injury without multisystem injury or major physiological changes. A threshold of RTS < 4 has been proposed to identify those patients who should be treated in a trauma centre, although this value may be somewhat low.
