INTRODUCTION: It has been suggested that changes to the training schemes of junior doctors and the increased pressure on emergency departments to manage their patients within a limited time might increase the number of unnecessary investigations performed on emergency admission patients. This, in turn, may lead to an increased number of investigations with normal results. In this study we try to analyse the role of the chest X-ray (CXR) as a diagnostic tool in patients presenting with acute abdominal pain. PATIENTS AND METHODS: A retrospective study was performed of the request forms and results of all chest radiography performed on patients admitted on the emergency surgical intake with acute abdominal pain through utilisation of the prospectively maintained electronic radiology database. The indications were compared to the guidelines published by the Royal College of Radiologists (RCR) which have been adopted as the standard of care. RESULTS: A total of 334 chest X-rays were identified of which only 23 (7%) had new findings. Four (1%) patients had free gas under the diaphragm. Of the CXRs, 258 (77%) were reported normal whilst 53 (16%) had old changes which were described in their hospital records and previous radiographs. Of the CXRs with new findings, only 20 were clinically significant and, of these, four (1%) were surgically significant. CONCLUSIONS: The majority of CXRs performed on emergency surgical admissions with abdominal pain are unnecessary. By obtaining a clear history, performing a thorough clinical examination and following the RCR guidelines most of the CXRs could be avoided. This would lead to less radiation exposure, reduce delays to diagnosis, and provide significant financial savings.
