Background NASBO recommends Computed Topography (CT) over plain abdominal X-ray (AXR) for the investigation of bowel obstruction (BO). AXR is routinely used within PAT for investigation of BO which may be exposing patients to unnecessary radiation and adding unnecessary cost to the service. Method A retrospective audit collected data on patients with CT confirmed BO between July 2019 and February 2020. This looked at the percentage of patients who had both CT and AXR to investigate BO. The cost of these AXRs and the percentage of these AXRs that were normal were also calculated. Results A search identified 141 patients with CT proven BO. 81/141(57.4%) patients had both AXR and CT as a part of their initial investigations. Of those patients 26/81(32.1%) had no AXR features suggestive of BO. Only 12/81(14.8%) of those patients had serial AXRs following initial imaging. The cost for one AXR is £34.15 which means £2766.15 was spent on potentially unnecessary AXRs within this period. Conclusions PAT is performing potentially unnecessary AXRs which is exposing patients to unnecessary radiation and costing the trust. Plain AXRs do not rule out BO. We have recommended an investigation flowchart to PAT A&amp;E departments to reduce unnecessary AXRs being performed.
