بررسی سرانجام بیماران ترومایی بستری در بیمارستان امام حسین (ع) شاهرود با استفاده از متدولوژی TRISS

Background & Objectives: Trauma database in the form of a registry can provide necessary information for monitoring and modifying trauma care. These databases can be collected based on trauma and injury severity score (TRISS) method. The injury severity score (ISS) is based on an anatomic severity classification of injury called abbreviated injury scale (AIS). TRISS determines the probability of survival of patient from the ISS and revised trauma score (RTS). RTS is a physiological scoring system that consists of GCS, systolic blood pressure and respiratory rate. Our aim was to report trauma outcome based on TRISS method and compare the outcome with the registry data from major trauma outcome study (MTOS). Methods: All trauma patients admitted between 1 April 2004 to 30 September 2005 with ISS> 10 were evaluated by TRISS method according to medical records, CT scan, sonography and surgical records. We used W and Z statistic to evaluate match of injury severity between our patients and MTOS database. Results: From the 220 patients studied, there were 174 (79.1%) males and 46 (20.9%) females and their mean age was 30.2 and 40.2, respectively. Blunt injury accounted for 9.1% patients, and 66.4% were admitted in ICU. Traffic accidents were the main cause of trauma (80%). There were 47 deaths, but the expected and predicted number of deaths should have been 35 and 38 according to MTOS norms. The average probability of survival (Ps) was 82.7%. W statistic was calculated as -4 with a Z score of 0.11. Conclusion: In our hospital, 4 deaths more than the MTOS database per 100 injured patients had occurred, and there was no other significant difference between our findings with the MTOS. In addition, the use of this model would be suitable for patient care in of pre-hospital, in-hospital and between hospital settings.
