1) The study assessed the incidence of coagulopathy in patients with moderate and severe traumatic brain injury (TBI) and identified risk factors for coagulopathy and poor outcomes. 2) Coagulopathy was present in 46% of patients and was more common in those with severe TBI (61%) than moderate TBI (30%). Risk factors for coagulopathy included effaced basal cisterns on CT scan and elevated D-dimer and lactate levels. 3) Risk factors for poor outcomes, including lower survival time, were severe TBI, midline shift, coagulopathy, high DIC score, and acidosis. Patients with coagulopathy, high DIC score, and
