Use our free Injury Severity Score (ISS) Calculator to quickly determine trauma severity. Input the Abbreviated Injury Scale (AIS) scores for six key body regions to get an accurate ISS, crucial for predicting patient outcomes and guiding treatment strategies.
Formula:
The Injury Severity Score (ISS) is calculated by summing the squares of the highest Abbreviated Injury Scale (AIS) scores from the three most severely injured body regions.
Formula: ISS = (AISRegion1)2 + (AISRegion2)2 + (AISRegion3)2
Where:
- AIS (Abbreviated Injury Scale): A score from 0 to 6 representing the severity of injury in a specific body region.
- Region1, Region2, Region3: The three body regions with the highest individual AIS scores.
