Abstract

Abstract : Introduction: Paediatricians play a significant role in preventive healthcare 1 . There is a strong link between radiation exposure and the development of cancer 2 . The typical dose of radiation required for an abdominal x-ray (AXR) is 0.46 mSv, which is the equivalent approximate dose to 35 chest x-rays 3 . AXRs are frequently ordered for children in our hospital by staff in paediatric, surgical and Emergency Departments (ED) who may be unaware of the guidelines surrounding clinical indications for AXRs. Aims: To review the indications for paediatric AXRs requested in our hospital and compare them to the Royal Children's Hospital, Melbourne (RCHM) Guidelines 4, which are considered the gold standard. Methods: AXRs performed in University Hospital Galway from 1st June - 30th November 2018, on children ≤14 years old, were identified. Those ordered from the Neonatal Intensive Care Unit and those ordered directly by the patient's General Practitioner were excluded. Details including patient age, clinical indication, requesting specialty, existing diagnoses and previous presentations with the same complaint were collected from the online radiology system. Results: A total of 132 AXRs were identified, 83 of which were included in the analysis. In accordance with RCHM guidance, 49.4% (n=41) of requests were appropriate. Bowel obstruction and foreign body ingestion were the commonest indications for appropriate requests; constipation and non-specific abdominal pain were the commonest inappropriate requests. The paediatric department requested 55 AXRs, 49% (n=27) considered appropriate; the surgical department requested 9, zero considered appropriate. The ED requested 17 AXRs, 70.5% (n=12) considered appropriate. Conclusion: During the 6-month period, over half of the AXR requests were deemed inappropriate and may have been avoided. Further education concerning AXR indications should be directed at paediatric and surgical teams primarily to minimise unnecessary investigations and limit radiation exposure.
