Mild head injury (GCS 14-15) or moderate and severe head injury GCS 13 and below. • The NICE guideline recommends a CT head scan within 8 hours of the injury in adults and children who have sustained a head injury with no other indications for a CT head scan and who are having warfarin treatment. 1 Traumatic brain injury (TBI) affects more than 1.7 million Americans yearly, and the proportion of Americans on anticoagulation is increasing (prescriptions at outpatient visits are up 38% from 2009 to . The data available to characterize the risk of adverse events in patients with MHI using DOAC are few and of poor quality. Background: In elderly patients on chronic anticoagulation (i.e. Falls resulting in a head injury are common among older adults.1, 2 Advanced age and anticoagulation are thought to be associated with an increased risk of intracranial hemorrhage (ICH) after a head injury.3 - 5 With the aging population and increasing use of anticoagulants, older patients on anticoagulation are commonly seen in the emergency department after a head injury. However, the risk of intracranial haemorrhage (ICH) in such patients is unclear, and further research has been recommended by the UK National Institute for Health and Care Excellence head injury guideline group. While the effects of Warfarin can be reversed, some of the newer oral anticoagulants do not have direct antidotes therefore management should focus on resuscitation and factor replacement. However, this is not the case for patients on anticoagulation—immediate discharge from ED after a normal head CT may not be appropriate. Head injury most commonly occurs as a result of falls from standing height in older adults. 2-6 Treatment with anticoagulant therapy can reduce the risk of thrombotic events after TBI, but this benefit must be balanced against the potential for . Li J, Brown J, Levine M. Mild head injury, anticoagulants, and risk of intracranial injury. Introduction: NICE guidelines provide clear indications for the investigation of head injuries with CT. A patient on anticoagulation is required to have lost consciousness to warrant a CT scan unless obvious stronger indications exist. Head injury most commonly occurs as a result of falls from standing height in older adults. A provisional written radiology report should be made available within 1 hour of the scan being performed. Background: Optimal anticoagulation therapy (AT) in patients with traumatic brain injury (TBI) is a challenging task and proper management is strongly correlated with clinical outcomes. We virtually all dutifully obey, because, even though the incidence of intracranial hemorrhage is low - it's still much higher than zero. Guidelines for the Acute Treatment of Cerebral Edema in Neurocritical Care Patients.

Background: Patients on anticoagulation who suffer traumatic injury or surgery are at risk for delayed We're lucky to have NICE guidelines in the UK. Treatment with anticoagulants and antiplatelet agents are well-known risk factors for an unfavourable outcome after traumatic brain injury (TBI). Multiply injured patients with a reduced level of consciousness should be managed by experienced staff using principles of Advanced Trauma Life Support. The haemorrhagic complications of head injury occur in up to 16% of anticoagulated patients sustaining a head injury. Joseph, B. et al.
