Coagulopathy upon ER admission is frequent after isolated blunt TBI and represents a powerful, independent predictor related to prognosis. Future research should aim to determine the beneficial effects of early treatment of TBI-associated coagulopathy.

When the original TASH-Score was applied onto the 2004-2007 TR-DGU database, a slight increase in discrimination was observed while precision was considerably lower. The predicted rate for MT within the development dataset was 13·9% while the observed incidence was 14·1%. In contrast, the predicted rate for MT within the revalidation dataset was 11·7%, while the observed rate was 8·4%. The logistic function to calculate MT probability was modified, and the TASH-Score was again evaluated against the most recent TR-DGU 2004-2007 database. The high performance of the score was not only restored but enhanced reflected by an increased ROC/AUC of 0·905. The score can be calculated quickly upon arrival of the patient in the emergency department and may be supportive to correct coagulopathy, to activate logistics and for research.

The risk factors from multivariate analysis correspond to the current understanding that coagulopathy is influenced by several clinical key factors; for example, an ongoing state of shock (at the scene and in the ED) was associated with a threefold increased risk of developing coagulopathy. When adjusted for all factors including the amount of prehospital intravenous fluids, a high colloid:crystalloid ratio was still associated with coagulopathy on admission to the ED. The recognition, prevention and management of the mechanisms and risk factors of coagulopathy aggravating haemorrhage after trauma are critical in the treatment of the severely injured patient.
