What is the Revised Trauma Score (RTS & T-RTS Survival Probability)?

📋Clinical Summary & Definition Capsule

The Revised Trauma Score (RTS & T-RTS Survival Probability) is an evidence-based clinical decision rule engineered to quantify diagnostic probability, stratify clinical severity, and guide therapeutic decision-making in emergency medicine practice. Implements the Champion Revised Trauma Score (RTS) combining Glasgow Coma Scale, Systolic Blood Pressure, and Respiratory Rate into coded and weighted physiological equations to guide prehospital trauma triage and TRISS survival benchmarking. Clinical scoring tools like Revised Trauma Score (RTS & T-RTS Survival Probability) are essential in acute and outpatient management, enabling clinicians to objectively differentiate between low-risk candidates suitable for conservative therapy and high-risk patients requiring urgent interventions. Verified against current 2026 clinical standards, this tool is extensively tested on Gulf health authority licensing exams including DHA (Dubai), SMLE (Saudi Arabia), MOH, HAAD/DOH (Abu Dhabi), OMSB (Oman), and QCHP (Qatar).

💡Clinical Pearls & Diagnostic Utility

Standardized prehospital physiological triage score that significantly reduces preventable trauma mortality by ensuring direct diversion to tertiary trauma centers.

Mathematical Formulation

Formula & Calculation Parameters

The mathematical equation and clinical variables required to calculate Revised Trauma Score (RTS & T-RTS Survival Probability):

Triage RTS = Coded GCS + Coded SBP + Coded RR (0 - 12)
Weighted RTS = 0.9368(GCS) + 0.7326(SBP) + 0.2908(RR) (0 - 7.84)

Clinical Limitations & Contraindications

When to Exercise Caution

Intubated or chemically paralyzed patients cannot be accurately assigned verbal GCS or spontaneous RR and require modified imputation.
