title: Assessment of mechanism, type and severity of injury in multiple trauma patients: A cross sectional study of a trauma center in Iran.
abstract: OBJECTIVE
  To accurately assess the mechanism, type and severity of injury in Iranian multiple trauma patients of a trauma center.
  
  
  METHODS
  Patients with multiple traumas referring to the emergency department of Hasheminejad University Hospital in Mashhad, Iran, entered this cross sectional study from March 2013 to December 2013. All the patients with injury severity score (ISS) > 9 were included in this study. Data analysis was performed by SPSS software (Version 11.5) and P values less than 0.05 were considered as significant differences.
  
  
  RESULTS
  Among the 6306 hospitalized trauma patients during this period, 148 had ISS>9. The male female ratio was 80%. The mean age of the patients was (33.5 ± 19.3) years. And 71% of the patients were younger than 44 years old. There were 19 (13%) deaths from which 68.5% were older than 44 years old. The mean transfer time from the injury scene to hospital was (55 ± 26) minutes. The most frequent mechanisms of injury were motorcycle crashes and falling from height, which together included 66.2% of all the injuries. A total of 84% of hospital deaths occurred after the first 24 h of hospitalization. Head and neck were the most common body injured areas with a prevalence of 111 cases (75%).
  
  
  CONCLUSIONS
  Motorcycle crashes have high frequency in Iran. Since most victims are young males, injury prevention strategies should be considered to reduce the burden of injuries.
