Organ injury scale


The Abbreviated Injury Scale (AIS) is an anatomical scoring system first introduced in 1969. It has been revised and updated against survival data so that it now provides a reasonably accurate way of ranking the severity of injury.

Injuries are ranked on a scale of 1–6, with 1 being minor, 5 severe, and 6 representing an unsurvivable injury (Table 1). This represents the “threat to life” associated with an injury and is not meant to represent a comprehensive measure of severity. An additional code of AIS9 is used to indicate an injury for which more detailed coding is not possible due to lack of information. The AIS is not a linear scale, in that the difference between AIS1 and AIS2 is not the same as that between AIS4 and AIS5. Organ Injury Scales of the American Association for the Surgery of Trauma are mapped to the AIS score for calculation of the Injury Severity Score.
