Routine X-rays in nasal trauma: the influence of audit on clinical practice.

The introduction of treatment protocols require audited prospective data. The use of X-rays in patients with simple nasal trauma is common but of limited value. A prospective audit of this practice and the implications of introducing a 'no X-ray' policy for these patients into the local casualty department are presented. Patients are spared radiation exposure and there are savings in patient throughput time and departmental costs. Casualty departments which have not already adopted such a policy are urged to do so. Where such a protocol is in use, audit to ensure adherence is encouraged.
