Computed tomography imaging in children with head trauma: utilization and appropriateness from a quality improvement...

Computed tomography (CT) imaging plays an important role in the acute evaluation and management of children with head trauma. When routine quality improvement (QI) meetings with representatives from the Children's Hospital radiology and emergency departments revealed disagreement regarding the utilization and appropriateness of CT in children presenting with head trauma, an interdepartmental QI team was formed to address this issue. Because formal criteria for obtaining CTs for head trauma were unavailable, internal institutional criteria were developed by consensus after literature review. Contrary to perceptions of some staff members, the majority (95%) of children who received CT met at least one of the established criteria over a one-year study period. There was little relationship between the presence of criteria and abnormal CT results, but decisions whether to admit patients to the hospital or to send them home were influenced by CT results. Follow-up studies suggested that patients who were discharged home with a normal CT or no CT had uniformly good outcomes.
