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.
Common questions
What is Revised Trauma Score (RTS)?
Quantify physiologic trauma severity with the Revised Trauma Score.
How is Revised Trauma Score (RTS) calculated? What is the core formula?
Coded GCS, SBP and RR (each 0–4); RTS = 0.9368·GCS + 0.7326·SBP + 0.2908·RR. Range 0–7.84.
When is Revised Trauma Score (RTS) used?
Field triage and trauma outcome prediction.
What are the key clinical points for Revised Trauma Score (RTS)?
Higher values indicate better physiology. RTS < 4 generally warrants trauma-centre transfer. Used within TRISS outcome methodology.
What are the limits and cautions when using Revised Trauma Score (RTS)?
For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
How is Revised Trauma Score (RTS) calculated in practice? Can you show a worked example?
Inputs: GCS 13–15 (4), Systolic BP > 89 (4), Respiratory rate 10–29 (4) → Result: RTS 7.841（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.） Inputs: GCS 3 (0), Systolic BP 0 (0), Respiratory rate 0 (0) → Result: RTS 0.000（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.）
