Trauma mortality in six university hospitals: Tehran, IRAN

Background: Trauma is the most common cause of mortality in the first four decades of life. In our country, cardiovascular diseases and trauma are leading causes of mortality, respectively. By gathering information on trauma mortalities, we can learn more about causes, and that knowledge can lead to prevention. Methods: This is a prospective descriptive study in Tehran during 12 months period (Sep 1999- Sep 2000). Two hundred and forty five trauma deaths in six hospitals were evaluated. The data was collected through a questionnaire, designed in Sina Trauma and Surgery Research Center (STSRC) used for the study. The questionnaires were completed by trained physicians visiting trauma patients in emergency room and wards round the clock. Data obtained included patient demographics, level of prehospital care, medical and operative procedures performed in emergency rooms (ER) and wards (according to ICD-10 coding), Glasgow Coma Scale (GCS) and vital signs at time of presentation to emergency rooms, Injury Severity Score (ISS), length of hospital stay and outcome of patients.Results: Twenty and forty five (3%) of 8000 trauma patients was died.  Mean age was 40.7 (±23.5) years old and 208 (84.9%) patients were male. The highest mortality rate was seen in the age group of 25 to 30 years. Road Traffic Accident was the main cause of death followed by falling with 174(71%) and 41(16.85), respectively. Among victims of road traffic accident, pedestrians and motorcyclists were prominent with 119 and 28 cases respectively. The majority of cases were dead due to head injuries (69%) and abdominal trauma was the second cause with 19 (7.8%) cases.Conclusions: Based on our findings the mechanism of injury have the positive effect on trauma outcome .Traffic accidents and assault is preventable and must be attended
