  1. We analyzed 4.817 patients, comparing 160 patients from our university hospital (LMU) to 4.657 trauma patients from other trauma centres (DGU) participating in the registry. SPB Systolic blood pressure; GCS Glasgow Coma Scale; ISS Injury Severity Score; NISS New Injury Severity Score; ICU Intensive Care Unit; AIS Abbreviated Injury Scale; MOF Multi Organ Failure (defined as organ failure of two systems of >2 SOFA-score points of at least 2 days duration [43]; TR Trauma room; PRBC Packed Red Blood Cells. p: χ2 test or Mann- Withney-U test (two sided). The overall mortality rate is not exactly equal to the rate of GOS "dead" due to the fact that GOS has not been documented for all patients.
