Definition & Operational Usage of Trauma Score
What Is Trauma Score?
A Trauma Score (such as the Revised Trauma Score / RTS) is an objective physiological scoring system combining GCS (1-4 pts), Systolic Blood Pressure (0-4 pts), and Respiratory Rate (0-4 pts) to generate a baseline score from 0 to 12 predicting trauma survival probability.
⚠️ Operational Safety Warning:Do not delay scene departure to calculate formal trauma scores — compute RTS en route after primary life threats are managed.
Why Trauma Score Matters on the Fireground
Calculating an RTS on scene provides an objective threshold for trauma triage. An RTS score < 11 indicates major trauma requiring immediate transport to a designated Level 1 or 2 Trauma Center.
Relevant NFPA Standards
- NREMT Standards: National Registry of Emergency Medical Technicians Practice Standards
- NFPA 455: Standard for Emergency Medical Services (EMS)
Field Procedures & Tactical Steps
- Assess baseline Glasgow Coma Scale (score 3-15 converted to RTS 0-4 points).
- Measure manual Systolic Blood Pressure (converted to RTS 0-4 points).
- Count Respiratory Rate (converted to RTS 0-4 points).
- Sum the three sub-scores to yield total RTS (range 0 to 12).
- Transmit RTS score to receiving trauma center during pre-notification.
Common Context & Application
Calculated during prehospital trauma evaluations, triage sorting, and trauma registry documentation.
Frequently Asked Questions about Trauma Score
What three physiological parameters form the Revised Trauma Score?
The Revised Trauma Score (RTS) measures Glasgow Coma Scale (GCS), Systolic Blood Pressure (SBP), and Respiratory Rate (RR).
What RTS score indicates major trauma requiring a Level 1 Trauma Center?
An RTS score of 11 or lower indicates severe trauma requiring direct transport to a high-level trauma facility.
