The use of CT in the management of minor head injuries in Queenstown.

Abstract

AIM This study retrospectively reviewed the management of head injury at Lakes District Hospital in Queenstown, New Zealand. The aim is to describe the management of minor head injury with particular reference to the current Traumatic Brain Injury guidelines of the New Zealand Guidelines Group. METHODS We identified all patients with head injury as a primary diagnosis who were seen in the Emergency Department at Lakes District Hospital during 2013-2015. We recorded clinical criteria indicating need for computed tomography (CT) scanning according to current guidelines for management of minor head injury. RESULTS A total of 883 patients were seen with head injury as their primary diagnosis: 280 patients aged >15 years had a minor head injury that met current criteria for immediate CT scanning. Of these, 66 (23.6%) actually had a CT head scan. CONCLUSION The rate of CT head scanning for minor head injury in Queenstown does not comply with current New Zealand guidelines.
