Bottom Line: More than 450,000 children visit emergency departments every year because of head trauma and many will undergo head computed tomography (CT) imaging, although few scans will show evidence of traumatic brain injury. Efforts have been made to avoid unnecessary CT imaging in children and to reduce radiation exposure. An information tool to help parents decide about care for their children with minor head trauma didn't reduce the rate of CT imaging in emergency departments in this randomized clinical trial. However, parent knowledge increased, they were more involved in decisions over CT use, and health care utilization decreased during the following week.
