Summary

Each year, Canadian emergency department physicians treat 600,000 patients with head injury. Many of these are adults with "minor head injury", i.e. loss of consciousness or amnesia and a Glasgow Coma Scale (GCS) score of 13-15. Only 6.2% of these "minor" patients have some acute injury on computed tomography (CT scan) and only 0.5% have an epidural hematoma requiring surgery. Among Canadian teaching hospital emergency departments, we have shown a fourfold variation in use of CT and that a small but important number of intracranial hematomas are missed at the first visit.
