About

Existing practice in emergency departments (ED) in the United Kingdom (UK) for managing patients taking warfarin after a blunt head injury is variable with little research that supports the most appropriate way to manage these patients. The investigators aimed to undertake research in order to understand the range and frequency of outcomes following head injury in this group of patients and to develop robust clinical guidance for how they should be optimally managed in the future.

Full description

This prospective observational study aims to enrol patients taking warfarin that attend participating ED's (up to 33) in England and Scotland after blunt head injury. Over an 18-month period from Oct 2011, ED attendance data will be collected from each ED as well as information from patient questionnaires about the care the patient received and the status of their health 6-10 weeks after the injury. Patients who died due to their head injury, experienced surgery due to their injury, had a change identified on a CT scan or re-attended the ED with a clear head injury complication are defined as experiencing a poor outcome. Information such as the patients' conscious state (GCS), level of clotting in their blood (INR) and symptoms will be investigated as predictors of a poor outcome. A mathematical model will be used to estimate the most cost-effective strategy assuming published National Institute for Health and Care Excellence (NICE) thresholds for cost per quality adjusted life year (QALY).
