The Abbreviated Injury Scale (AIS) is an anatomical-based coding system created by the Association for the Advancement of Automotive Medicine to classify and describe the severity of injuries. It represents the threat to life associated with the injury rather than the comprehensive assessment of the severity of the injury. AIS is one of the most common anatomic scales for traumatic injuries. The first version of the scale was published in 1969 with major updates in 1976, 1980, 1985, 1990, 1998, 2005, 2008 and 2015.
