Concussion in the emergency department: a review of current guidelines.

The annual number of emergency department (ED) visits for traumatic brain injury (TBI) is rising in the United States, with the majority of these visits resulting in a diagnosis of mild traumatic brain injury (mTBI), or concussion. There are limited data to support objective clinical measures to guide the management of concussion, but several guidelines have been published that provide recommendations for evaluation and management of concussion and mTBI. This supplement provides a summary of 2 recently published, consensus-based guidelines and discusses practical aspects of ED management of patients with concussive injuries, including the initial evaluation, diagnostic criteria, assessment tools, and aftercare recommendations.
