Implementation of pediatric cervical spine clearance guidelines at a combined trauma center: Twelve-month impact.

Background: Pediatric cervical spine clearance guidelines should reduce computed tomography (CT) usage in combined pediatric and adult trauma centers biased by adult CT clearance.

Methods: Cervical spine clearance under age 15 years was compared 12 months before (128 patients) and after (105 patients) guideline implementation, emphasizing National Emergency X-Radiography Utilization Study (NEXUS) criteria when appropriate.

Results: CT scans in patients clearable by NEXUS criteria decreased 23% (p = 0.
