Background Traumatic brain injury (TBI) in combination with shock has been associated with hypocoagulability. However, recent data suggest that TBI itself can promote a systemic procoagulant state via the release of brain-derived extracellular vesicles. The objective of our study was to identify if TBI was associated with differences in thrombelastography indices when controlling for other variables associated with coagulopathy following trauma. We hypothesized that TBI is independently associated with a less coagulopathic state. Methods Prospective study includes all highest-level trauma activations at an urban Level I trauma center, from 2014 to 2020. Traumatic brain injury was defined as Abbreviated Injury Scale head score greater than 3. Blood samples were drawn at emergency department admission. Linear regression was used to assess the role of independent predictors on trauma induced coagulopathy. Models adjusted for Injury Severity Score (ISS), shock (defined as ED SBP108, or first hospital base deficit >10), and prehospital Glasgow Coma Scale score. Results Of the 1,023 patients included, 291 (28%) suffered a TBI. Traumatic brain injury patients more often were female (26% vs. 19%, p = 0.01), had blunt trauma (83% vs. 43%, p
