title: Niguarda Trauma Team: outcome of three years of activity.
abstract: BACKGROUND
  The aim of this study was to prove the existence of a direct relationship between the comprehensive strategy of trauma management and an enhancement in outcome. Tests were carried out on the impact of the Niguarda Trauma Team System on mortality rates due to severe trauma.
  
  
  METHODS
  The epidemiological data was retrospectively reviewed along with, the severity scores: Abbreviated Injury Scale (AIS), Injury Severity Score (ISS), Revised Trauma Score (RTS), Probability of survival (Ps) and the outcome of severe trauma admitted to Niguarda hospital between October 2002 and September 2005. All data were collected from the Trauma Registry of the Niguarda Hospital. Two subsequent periods of 20 and 16 months were compared.
  
  
  RESULTS
  Nine hundred forty-two severe traumas (94.05% blunt trauma) were recorded with an overtriage rate of 36.09%. Most patients were admitted for bone and muscular injuries (52.22%). Excluding the patients who were overtriaged, there were 129 patients who died. Comparing the two periods, the Authors observed a significant reduction in mortality from 22.56% to 19.75%, mainly related to a decrease in early mortality due to hemodynamic instability. Central nervous system injury was the main cause of death (65%). Average hospital stay significantly decreased from 17.01+/-12.07 days to 14.97+/-10.34 days.
  
  
  CONCLUSIONS
  Introducing a comprehensive strategy of severe trauma management, the Niguarda Trauma Team System had a significant impact on mortality rates and hospital stay.
