Injury scoring

Trauma systems rely on accurate injury severity scoring to describe and study trauma patient populations. In NSW, the key criterion for including a patient record in the NSW Trauma Registry is a classification of injuries as moderate to critical, based upon an internationally recognised anatomical scoring system known as the Abbreviated Injury Scale (AIS) and the Injury Severity Score (ISS)1.

The AIS and ISS is used by accredited staff at each hospital trauma registry to score individual patient injuries and their severity, and provides a common tool for comparing and selecting patient records for inclusion in the NSW Trauma Registry.
