ANALYSIS OF TRAUMA OUTCOME AT A UNIVERSITY HOSPITAL IN ZAHEDAN, IRAN USING THE TRISS METHOD
Abstract
Objective: To evaluate validity of TRISS (Trauma score and injury severity score) method in trauma outcome analysis and compare trauma care at a university hospital, with the standards reported in the Major Trauma Outcome Study (MTOS).
Design: Analytical and descriptive study.
Setting: Khatam-ol-anbia University Hospital in Zahedan, Iran, from March 22, 1997 to March 21, 1998.
Subjects: Seven hundred and sixty eight consecutive patients with multiple trauma were included in the study. Survival analysis was completed for all of the patients.
Results: The majority of patients were men (82%), and the average age was 23 years. Seven hundred and one patients (91%) sustained blunt trauma, with road traffic accidents being the most common (59%). The predicted mortality was 3.1% and the observed mortality was 8%. The M-statistics was 0.91.
Conclusion: In developing countries the same as developed countries, the TRISS methodology is an acceptable method for evaluation of the difference between predicted and observed mortality. This study shows that our mortality is significantly more than universal standards and there are weak points in our trauma care system.
