Management of mild traumatic brain injury in the emergency department.

With over 1.7 million people in the United States seeking medical attention for head injury each year, emergency clinicians are challenged daily to screen quickly for the small subset of patients who harbor a potentially lethal intracranial lesion while minimizing excessive cost, unnecessary diagnostic testing, radiation exposure, and admissions. Whether working at a small, rural hospital or a large inner-city public hospital, emergency clinicians play a critical role in the diagnosis and management of mild traumatic brain injury. This review assesses the burgeoning research in the field and reviews current clinical guidelines and decision rules on mild traumatic brain injury, addressing the concept of serial examinations to identify clinically significant intracranial injury, the approach to pediatric and elderly patients, and the management of patients who are on anticoagulants or antiplatelet agents or have bleeding disorders. The evidence on sports-related concussion and postconcussive syndrome is reviewed, and tools for assessments and discharge are included.
