ICU scoring systemstrauma

Scoring systems have been developed in trauma for:

• Rapid field triage to direct the patient to appropriate levels of care

• Quality assurance

• Developing and improving trauma care systems by categorising patients and identifying problems within the systems

• Making comparisons between groups from different hospitals, in the same hospital over time, and/or undergoing different treatments

The Injury Severity Score (ISS) is a severity scoring system patients based on the anatomical injuries sustained. The Revised Trauma Score (RTS) utilises measures of physiological abnormality to predict survival. A combination of ISS and RTS—TRISS — was developed to overcome the shortcomings of anatomical or physiological scoring alone. The TRISS methodology uses ISS, RTS, patient age and whether the injury was blunt or penetrating to provide a measure of the probability of survival.
