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 | 6–8 (2) |
|---|---|
| Systolic BP | 50–75 (2) |
| Respiratory rate | 6–9 (2) |
→RTS3.920
- Coded values：GCS 2, SBP 2, RR 2 (each 0–4)
- Interpretation：High severity (range 0–7.84; higher = better)
- Triage：RTS < 4 generally warrants transfer to a trauma centre.
| 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.
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. Code GCS, SBP and respiratory rate into 0–4 categories and compute RTS = 0.9368·GCSc + 0.7326·SBPc + 0.2908·RRc (range 0–7.8408).
When is Revised Trauma Score (RTS) used?
Field triage and trauma outcome prediction.
How should Revised Trauma Score (RTS) results be interpreted?
Higher RTS reflects better physiology; values under ~4 commonly trigger trauma-centre transfer and intensify triage within TRISS methodologies.
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)?
Requires accurate coded physiology — do not mix raw GCS with coded SBP/RR. Prehospital values may differ from ED arrival; document the time point. Use with anatomic injury scores (ISS) rather than as a sole operative trigger. 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.
Does Revised Trauma Score (RTS) upload patient data? Where is it calculated?
Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
How is Revised Trauma Score (RTS) calculated in practice? Can you show a worked example?
Inputs: GCS 6–8 (2), Systolic BP 50–75 (2), Respiratory rate 6–9 (2) → Result: RTS 3.920（Coded values: GCS 2, SBP 2, RR 2 (each 0–4), Interpretation: High severity (range 0–7.84; higher = better), Triage: RTS < 4 generally warrants transfer to a trauma centre.） 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.）
