Study of Pre Hospital Management of Polytrauma Patients by Medical Teams From a Department in the Parisian Region

To study the impact of prehospital management duration by SMUR teams in the Essonne department (91) on early patient mortality (within 24 hours) and to analyze the procedures performed on scene. The study hypothesis is that all-cause in-hospital mortality may be associated with the duration of prehospital care, with either a beneficial impact related to the performance of life-saving interventions or a negative impact due to prolonged time to access definitive treatment. Identifying potential factors associated with prolonged prehospital management times could help define possible areas for improvement and future interventions.
