Conversion of Abbreviated Injury Scale AIS 85 to Abbreviated Injury Scale AIS 90 and the application of the injury impairment scale to real-world crash data.

The long awaited AAAM Injury Impairment Scale IIS has been applied to the United Kingdom Co-operative Crash Injury Study field data. A total of 29.946 injuries, collected over a ten year period (1983-1992) were re-coded from the Abbreviated Injury Scale (AIS) 85 version to AIS 90 to allow easy allocation of the IIS. The difficulties associated with re-coding and the comptability between scales are described. Priorities of injury mitigation based on IIS are compared with those from AIS. The data concerning injured restrained front seat occupants is examined to establish the most frequent cause of both impairing and life-threatening injuries to each body region in different impact configurations.
