BACKGROUND:: The original Trauma and Injury Severity Score (TRISS) methodology from the Major Trauma Outcome Study (MTOS) is the most widely used outcome prediction model. The coefficients from the MTOS cohorts are still used in the Japan Trauma Data Bank for evaluating the quality of patient care. The purposes are to determine whether the database of this institution is well matched to the MTOS study and whether the original TRISS coefficients are accurate predictors of the patient outcome in Japan. METHODS:: The M-statistic score was calculated based on the trauma registry data from 2000 to 2003 in Teikyo University. RESULTS:: Eight hundred fifty-four cases were analyzed. The crude mortality rate was 10.5%. The mean Injury Severity Score was 15.8 ± 13.6. The mean Revised Trauma Score was 7.00 ± 1.4. The M-statistic score was 0.811. CONCLUSION:: The trauma populations in this study differed significantly from the MTOS. The Modified TRISS coefficients should be adapted for outcome assessment based on the location of the injured population. This is the first report of an M-study from Japan to be published in the English literature.
