Short description

Injury Severity Score.


Whole number (0-75)

7777 Not Applicable
9999 Unknown


The Injury Severity Score (ISS) is an anatomical scoring system that provides an overall score for patients with multiple injuries.

Each injury is assigned an Abbreviated Injury Scale (AIS) score, allocated to one of six body regions (Head, Face, Chest, Abdomen, Extremities (including Pelvis), External).

Only the highest AIS score in each body region is used.

The 3 most severely injured body regions have their score squared and added together to produce the ISS score.

This is an ordinal scale.

Please note that because of its calculation, there are some values that are not possible to obtain for the ISS (7, 15, 23, 28, 31, 37, 39, 40, 44, 46, 47, 49, 52, 53, 55, 56, 58, 60-65 and 67-74).
