Rapidly Assess Trauma Severity in the Field

When every second counts in trauma care, having a standardised, objective severity assessment tool can mean the difference between life and death. The Revised Trauma Score Calculator computes the RTS from three physiological parameters measured at the scene or on arrival - respiratory rate, systolic blood pressure, and Glasgow Coma Scale score. It is one of the most widely used prehospital and emergency department triage tools in trauma systems worldwide.

The Revised Trauma Score was designed to be simple enough for paramedics to calculate in the field while being statistically powerful enough to predict survival probability. Each parameter is coded into a value from 0 to 4, and the weighted sum produces a score that correlates directly with expected survival. This tool performs the calculation instantly and provides the corresponding survival estimate.

How to Calculate the Revised Trauma Score

Enter the patient's Glasgow Coma Scale score (3-15), systolic blood pressure (mmHg), and respiratory rate (breaths per minute). Each parameter is converted to a coded value (0-4) based on established ranges. The RTS is then calculated as: (0.9368 x GCS coded value) + (0.7326 x SBP coded value) + (0.2908 x RR coded value).

Scores range from 0 (worst) to 7.8408 (best). The calculator displays the total RTS, the individual coded values, and the estimated probability of survival. An RTS below 4 indicates a patient with less than 60% predicted survival who requires immediate transfer to a major trauma centre.

Who Uses the Revised Trauma Score?

Paramedics and emergency medical technicians use RTS as a field triage tool to determine which hospital a trauma patient should be transported to. Trauma surgeons and emergency physicians calculate it on arrival to categorise injury severity. Trauma registries use RTS as a core component of outcome data and quality metrics.

The Revised Trauma Score Calculator is also integral to the TRISS methodology (Trauma and Injury Severity Score), which combines RTS with the Anatomical Injury Score to produce more refined survival predictions used in trauma research and institutional benchmarking.

Triage Applications

In mass casualty incidents, RTS provides an objective basis for triage decisions that might otherwise rely entirely on individual clinician judgment under extreme stress. Patients with the highest RTS scores and therefore the best chance of survival can be prioritised for immediate treatment when resources are limited - a difficult but necessary calculus in disaster medicine.

Limitations and Context

The RTS uses only physiological parameters and does not account for the mechanism of injury or anatomical injuries. A patient with a penetrating abdominal wound may have a normal RTS initially but deteriorate rapidly. Intoxication can artificially lower the GCS component. Paediatric patients have different normal physiological ranges that the standard RTS does not account for. Always use the RTS as one component of a comprehensive trauma assessment, supplementing it with mechanism of injury evaluation, physical examination findings, and clinical judgment. The score is most valuable as a triage and communication tool - providing a standardised language for describing trauma severity across the care chain.
