Time distribution of mortality of patients activating a major haemorrhage protocol and receiving at least one unit of red blood cell transfusion. Overall mortality reduced 25% from 2009 to 2015. A drop in prehospital mortality resulted in a 50% higher death rate immediately post-admission. Improvements in management of coagulopathy dramatically reduced mortality rates between 3 and 24 h but were associated with a 44% increase in later deaths [10].
