[Polytrauma and predicting fatality. Comparative evaluation of the value of the Kirkpatrick-Youmans Trauma Index (TI), Schreinlechner-Eber modified TI (TI mod.), and the Baker Injury Severity Score].

The Trauma Index (TI) of Kirkpatrick and Youmans modified by Schreinlechner and Eber performed better than the Injury Severity Score (ISS) in predicting case fatality of 234 patients with major trauma treated during the years 1985 through 1987. Logistic regression was used for determining the cut-points: Death was considered as predicted by ISS if it was greater than 53 or by TI if it was greater then 3.74. Specificity was 95% for ISS and 94% for TI. Sensitivity was 49% for ISS and 73% for TI.
