ACEP Clinical Policy — Mild Traumatic Brain Injury (Concussion) in the ED (2023)

The ACEP 2023 Clinical Policy on evaluation and management of adult patients with mild traumatic brain injury (mTBI) / concussion in the emergency department synthesizes evidence for: CT head imaging decision rules (Canadian CT Head Rule, NEXUS II, New Orleans Criteria), intracranial hemorrhage risk stratification in anticoagulated patients, observation vs. discharge decision-making, post-concussion follow-up, and specific populations (anticoagulated patients, elderly). Concussion (mTBI) represents approximately 70–90% of all TBI presentations to EDs and is the most common traumatic brain injury encountered in emergency practice.
