Abstract

This paper examines the validity of the AIS as a measure of four specific dimensions of injury severity. The analysis is based on comparing the AIS scores of 95 injuries selected from AIS-80 to the scores these injuries received on four unidimensional injury severity scales, namely: mortality risk, acute care length of stay, overall recovery period, and permanent disability/activity limitation. The unidimensional injury severity scale scores were based on the subjective estimates of a sample of physicians (n = 218) involved in the care of trauma patients. Based on bivariate and partial correlation analysis, results suggest that the AIS can be defined as a scale which measures both trauma related mortality risk and acute care length of stay. However, the use of the AIS as an indicator of trauma related recovery period and permanent disability is questioned.
