When to use
Field triage and trauma outcome prediction.
How it works
Coded GCS, SBP and RR (each 0–4); RTS = 0.9368·GCS + 0.7326·SBP + 0.2908·RR. Range 0–7.84.
Key points
- Higher values indicate better physiology.
- RTS < 4 generally warrants trauma-centre transfer.
- Used within TRISS outcome methodology.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| GCS | 13–15 (4) |
|---|---|
| Systolic BP | > 89 (4) |
| Respiratory rate | 10–29 (4) |
→RTS7.841
- Coded values：GCS 4, SBP 4, RR 4 (each 0–4)
- Interpretation：Lower severity (range 0–7.84; higher = better)
- Triage：RTS < 4 generally warrants transfer to a trauma centre.
| GCS | 3 (0) |
|---|---|
| Systolic BP | 0 (0) |
| Respiratory rate | 0 (0) |
→RTS0.000
- Coded values：GCS 0, SBP 0, RR 0 (each 0–4)
- Interpretation：High severity (range 0–7.84; higher = better)
- Triage：RTS < 4 generally warrants transfer to a trauma centre.
