The Abbreviated Injury Scale AIS and derived scores such as the Injury Severity Score ISS are commonly used to quantify injury severities in trauma registries. To reflect contemporary trauma management and treatment the most recent version of the AIS AIS08 contains many codes which differ in severity from their equivalents in the earlier 1998 version AIS98 . Consequently the adoption of AIS08 may impede comparisons between data coded using different AIS versions. It may also affect the number of patients classified as major trauma. Methods The entire AIS98-coded injury dataset of a large population based trauma registry was retrieved and mapped to AIS08 using the currently available AIS98-AIS08 dictionary map. The percentage of codes which had increased or decreased in severity or could not be mapped was examined in conjunction with the effect of these changes to the calculated ISS. The potential for free text information accompanying AIS coding to improve the quality of AIS mapping was explored. Results A total of 128280 AIS98-coded injuries were evaluated in 32134 patients 15471 patients of whom were classified as major trauma. Although only of dictionary codes decreased in severity from AIS98 to AIS08 this represented almost 13 of injuries in the registry. In of patients no injuries could be mapped. ISS was potentially unreliable in one-third of patients as they had at least one AIS98 code which could not be mapped. Using AIS08 the number of patients .
