Revised Trauma Score Calculator
Assess trauma severity and survival probability using physiological parameters
RTS Assessment
1. Glasgow Coma Scale (GCS) Score
Enter the total GCS score (3-15). This assesses eye opening, verbal response, and motor response.
Coded Value: 0
13-15=4, 9-12=3, 6-8=2, 4-5=1, 3=0
2. Systolic Blood Pressure (SBP)
Enter the systolic blood pressure in mmHg. This reflects cardiovascular status.
Coded Value: 0
>89=4, 76-89=3, 50-75=2, 1-49=1, 0=0
3. Respiratory Rate (RR)
Enter the respiratory rate per minute. This reflects respiratory function.
Coded Value: 0
10-29=4, >29=3, 6-9=2, 1-5=1, 0=0
RTS Formula
RTS = (0.9368 × GCS) + (0.7326 × SBP) + (0.2908 × RR)
Weighting Factors:
- • GCS: 0.9368 (highest weight)
- • SBP: 0.7326 (medium weight)
- • RR: 0.2908 (lowest weight)
Survival Probabilities
Understanding the Revised Trauma Score
What is the Revised Trauma Score?
The Revised Trauma Score (RTS) is a physiological scoring system used to assess the severity of injury in trauma patients. It combines three simple clinical measurements that are routinely obtained in emergency settings: Glasgow Coma Scale, systolic blood pressure, and respiratory rate.
Clinical Applications
- •Triage decisions in emergency departments
- •Trauma center activation criteria
- •Research and quality improvement
- •Prognostication and family communication
RTS Components
Glasgow Coma Scale (Weight: 0.9368)
Assesses neurological function through eye opening, verbal response, and motor response. Most heavily weighted component reflecting brain injury severity.
Systolic Blood Pressure (Weight: 0.7326)
Reflects cardiovascular status and perfusion. Critical for assessing hemodynamic stability.
Respiratory Rate (Weight: 0.2908)
Indicates respiratory function and metabolic status. Lowest weighted but still important.
Clinical Decision Making
RTS ≤ 4
Severe Trauma: Requires immediate trauma center care. High mortality risk with survival probability <61%.
RTS 4-6
Moderate Trauma: Consider trauma center based on mechanism and associated injuries. Good survival probability.
RTS > 6
Mild Trauma: Excellent prognosis with survival probability >97%. Standard care with monitoring.
Important: RTS should be used alongside clinical judgment, mechanism of injury, and anatomical findings. It is a tool to aid decision-making, not replace comprehensive trauma assessment.
