Revised UK guidelines from the National Institute for Health and Clinical Excellence (NICE) for the management of acute head injury address the initial management and triage/ Evidence has also shown that even patients who have sustained a minor head injury have difficulty reintegrating into society.5 Thus, management of head injury is an important topic. The principles for the triage of patients with head injuries were set out in the Royal College of Surgeons' report in 2005.11 This report and the Scottish Intercollegiate Guidelines Network6 were largely based on clinical risk factors and the presence of a skull fracture radiograph.15 This approach resulted in about 5% of patients (about 50000 patients per year in the UK) with head injury proceeding to a CT scan.
