title: Does the National Emergency X-ray Utilization Study make a difference?
abstract: OBJECTIVE
  To assess whether the introduction of the National Emergency X-ray Utilization Study guidelines in a UK emergency department reduced the number of patients having cervical spine radiographs and altered the accuracy of diagnosis of cervical spine injury.
  
  
  METHODS
  This was a prospective, observational study. The number of patients with recent neck injury who had cervical spine radiographs taken was assessed for 3 months before and three months after the introduction of the National Emergency X-ray Utilization Study guidelines to an urban emergency department in the UK. The number of injuries missed by emergency department doctors during the two 3-month periods was also recorded.
  
  
  RESULTS
  Prior to using the guidelines, 252 of 715 patients (35%) were X-rayed and when using the guidelines, 268 of 706 patients (38%) were X-rayed. No significant difference was observed between the rates of X-ray in the two groups (P=0.288). No injuries were missed by emergency department doctors either before or after the introduction of the guidelines.
  
  
  CONCLUSIONS
  Introduction of the National Emergency X-ray Utilization Study guidelines to a UK emergency department did not reduce the number of patients having cervical spine radiographs after neck trauma and had no effect on the pick-up rate for cervical spine injuries.
