Every year, thousands of people in Germany succumb to severe injuries. But what causes the death of these patients? In addition to the trauma, pre-traumatic health status, age, and other influencing factors play a role in the outcome after trauma. This study aims to answer the question of what causes the death of a severely injured patient.For this publication, in addition to previously published results, we examined current data from patients in German hospitals from the years 2015-2022 (8 years) documented in the TraumaRegister DGU®. The feature "Presumed Cause of Death", introduced in 2015, was considered. Patients transferred out early (<48h) as well as patients with minor injuries were excluded from this analysis.The number of fatalities decreases over time and does not correspond to a traditionally postulated tri-modal mortality distribution. Instead, over time, the distribution of causes of death shows significant variation. In over half of the cases (54%), traumatic brain injury (TBI) was the presumed cause of death, followed by organ failure (24%) and haemorrhage (9%). TBI dominates, especially in the first week, haemorrhage in the first 24h, and organ failure as a cause steadily increases over time.In summary, it can be observed that the risk of death due to trauma-related consequences is highest in the first minutes, hours, and days, decreasing steadily over time. Particularly, the extent of injuries, head injuries, and significant blood loss are early risk factors.
