Each injury was coded using the Abbreviated Injury Scale 1998 and 2005. The statistical tests applied were the Wilcoxon, McNemar-Bowker, Kappa, and Z tests.ResultsComparing the two versions resulted in significant disagreement regard ing the scores of certain body regions. With the 2005 version, injury and trauma severity levels were significantly decreased, and the mortality was higher at lower scores.ConclusionInjury and trauma severity were decreased and the percentage mortality was changed when the 2005 revision of the Abbreviated Injury Scale was used.
