Background: Using a valid system for assessing the severity of injuries in blunt trauma plays a great role in prognosis of the patients. The Injury Severity Score (ISS) is an anatomical scoring system that provides an overall score for patients with multiple injuries. Methods: In a 2 months period, injury severity scores were obtained for 254 consecutive hospitalized patients with traffic accidents, after initial diagnostic evaluations. For its computation, the score squares of the 3 most severely injured body regions according to AIS (Abbreviated Injury Scale) are added together. The score of ISS ranges from 0 (no injuries) to 75 (not compatible with life). Results: A total of 254 patients (89% male) were studied. Ninety percent had lower than 50 years old age (the mean of age was 23 years). The score of ISS in %17 of patients was lower than 25. The mortality rate was %4/6 (12 cases) and their mean ISS was 37. The critical score of ISS for death was 25. Conclusion: Increase of the ISS score to more than 25 is correlated with an increase in risk of mortality in patients with traffic accident. The Injury Severity Score is a significant prognostic predictor for patients with blunt trauma.
