title: The usefulness of routine preoperative chest X-rays and ECGs: a prospective audit.
abstract: BACKGROUND
  Pre-operative Chest X-ray (CXR) and electrocardiograms (ECG) are routinely ordered locally for patients above a certain age. This study examines the usefulness of such a practice and its clinical impact.
  
  
  METHODS
  Prospective audit of 875 consecutive anaesthetic patients over a one-month period, assessing the proportion and impact of abnormal CXR or ECG findings.
  
  
  RESULTS
  The proportion of patients with abnormal CXR or ECG increased with worsening ASA status. There was little impact of routine pre-operative CXR and ECG on anaesthetic management. Only 11/324 CXR and 13/375 ECG affected anaesthetic technique or choice of therapeutic procedure.
  
  
  CONCLUSIONS
  Targeted investigations should be performed as indicated by clinical findings rather than on the basis of arbitrary age cut-offs.
