TRISS SCORING OF THE MULTI-TRAUMA PATIENTS DURING APRIL 2005-MARCH 2006 IN URMIA UNIVERSITY OF MEDICAL SCIENCES

Evaluation of trauma management is usually by TRISS scoring and the outcome is compared to data from Major Trauma Outcome study (MTOS). Same study was designed in Urmia. TRISS scoring was performed for multiple trauma cases during April2005-March 2006 in Shahid Motahhari hospital and was compared to MTOS via W-M-Z statistics. 260 consecutive patients were included in the study, 210 men and 50 women. Mean age was 30.31 yr. 91% sustained blunt trauma, the vast majority resulting from traffic accident (92.5%). Observed mortality was 52 and predicted mortality 42. The W-M-Z statistics were: s 3.8%-0.891-0.27. The value of M- statistic > 0.880 predicted that this study was comparable to MTOS data. Z statistic between ranges -1.96- +1.96 defined standard treatment and there was no significant mortality difference. TRISS scoring and MTOS comparing are valid for multi-trauma patients, outcome analysis in Iran.
