Revised Trauma Score
7.84
How to Use This Calculator
- Enter the Glasgow Coma Scale (GCS) total score (3-15).
- Input Systolic Blood Pressure (mmHg) and Respiratory Rate (breaths/min).
- Review the Revised Trauma Score (RTS) — the sum of coded GCS, SBP, and RR values.
- Check Estimated Survival Probability (%) — correlates with hospital outcome in major trauma.
- Use Triage Priority (Immediate/Urgent/Delayed) to guide transport and resource allocation.
What each input means
- Glasgow Coma Scale (GCS)
- GCS score from 3 (deep coma) to 15 (fully alert).
- Systolic Blood Pressure (mmHg)
- Systolic BP in mmHg. Enter 0 if no pulse detected.
- Respiratory Rate (breaths/min)
- Breaths per minute. Enter 0 if apneic.
What each result means
- Revised Trauma Score
- RTS ranges from 0 (worst) to 7.8408 (best).
- GCS Coded Value (0-4)
- Coded GCS component for RTS calculation.
- SBP Coded Value (0-4)
- Coded systolic BP component for RTS calculation.
- RR Coded Value (0-4)
- Coded respiratory rate component for RTS calculation.
- Estimated Survival Probability (%)
- Logistic regression estimate based on RTS (Boyd et al.).
- Triage Priority (1=Immediate, 2=Urgent, 3=Delayed)
- Field triage category based on RTS score.
How this is calculated
Worked example, using the default values
- Identify Input ParametersGlasgow Coma Scale (GCS) = 15, Systolic Blood Pressure (mmHg) = 120, Respiratory Rate (breaths/min) = 16 = 3 input(s) provided
- Calculate Revised Trauma ScoreRevised Trauma Score = round(rts * 1000) / 10007.841 = 7.841
- Calculate GCS Coded ValueGCS Coded Value4 = 4
- Calculate SBP Coded ValueSBP Coded Value4 = 4
