Overall distribution of trauma-related deaths in Berlin 2010: advancement or stagnation of German trauma management?

Abstract

Background: Trauma is the leading cause of death among children, adolescents, and young adults. The latest data from the German Trauma Registry reveals a constant decrease in trauma mortality, indicating that 11.6 % of all trauma patients in 2010 died in hospital. Notably, trauma casualties dying before admission to hospital have not been systematically surveyed and analyzed in Germany.

Methods: We conducted a prospective observational study of all traumatic deaths in Berlin, recording demographic data, trauma mechanisms, and causes/localization and time of death after trauma. Inclusion criteria were all deaths following trauma from 1 January 2010 to 31 December 2010.

Results: A total of 440 trauma fatalities were included in this study, with a mortality rate of 13/100,000 inhabitants; 78.6 % were blunt injuries, and fall from a height >3 m (32.7 %) was the leading trauma mechanism. 32.5 % died immediately, 23.9 % died within 60 min, 7.7 % died within 1-4 h, 16.8 % died within 4-48 h, 11.1 % died <1 week later, and 8 % died >1 week after trauma. The predominant causes of death were polytrauma (45.7 %), sTBI (38 %), exsanguination (9.5 %), and thoracic trauma (3.2 %). Death occurred on-scene in 58.7 % of these cases, in the intensive care unit in 33.2 %, and in 2.7 % of the cases, in the emergency department, the operating room, and the ward, respectively.

Conclusions: Polytrauma is the leading cause of death, followed by severe traumatic brain injury (sTBI). The temporal analysis of traumatic death indicates a shift from the classic "trimodal" distribution to a new "bimodal" distribution. Besides advances in road safety, prevention programs and improvement in trauma management-especially the pre-hospital phase-have the potential to significantly improve the survival rate after trauma.
