Every year, more than 20,000 patients with polytrauma are treated in Germany. The term polytrauma refers to simultaneous injury to several body regions that are individually or collectively life-threatening for the patient. However, this assessment is made based on appropriate scoring systems. Adequate treatment of these patients requires not only medical care at the highest level, but also coordination of organizational/logistical processes. The link between preclinical and clinical care is treatment in the shock room, which should be led by a defined, experienced "trauma leader". Treatment algorithms are based on the current S3 guideline Polytrauma/Serious Injury Treatment of the AWMF and the White Paper on Serious Injury Care. Here, recommendations are defined regarding personnel, spatial, logistical and material requirements. Every shock room team should be trained regularly and have theoretical and practical knowledge on the application of shock room algorithms. This can improve the quality of treatment and thus the probability of survival of critically ill patients. In the shock room itself, the focus is on standardized and priority-oriented assessment and stabilization of the patient. Due to the varying quality of care for severely injured patients in Germany, the TraumaNetwork DGU® initiative was implemented by the German Society of Trauma Surgery to improve the treatment of polytrauma patients by defining standards and improving processes and organization in the care of severely injured patients. In Germany, there are currently 615 participating hospitals that are organized in 52 local trauma networks, some of which are cross state borders.
