TTP5.12 A Trust-Wide Audit Evaluating Gallbladder and Biliary Tree Ultrasound Reporting and Compliance with The Royal College of Radiologists Standards

Background Gallbladder and biliary tree ultrasound is the gold-standard imaging modality for diagnosing gallbladder pathology. Adherence to the Royal College of Radiologists' (RCR) standards ensures an accurate and consistent reporting system. Aim To assess adherence to the Royal College of Radiologists' gallbladder and biliary tree ultrasound standards, including gallbladder neck, bile echogenicity, wall thickness, common bile duct (CBD) assessment, and CBD lumen measurement. Method The first cycle involved a retrospective review of the ultrasound scans of 70 patients at Princess of Wales Hospital (POWH) and Neath Port Talbot Hospital (NPTH). The results were presented in the joint audit meeting. We implemented several interventions, including introducing a new local reporting protocol, educational posters, and teaching sessions on gallbladder US reporting. In the second cycle, prospective data of 45 patients at POWH and NPTH was reviewed and presented. Results In the first cycle, adherence was as follows:Gallbladder neck assessed: (7.1%)Echogenicity of bile reported: (17.1%)Wall thickness commented on: (55.7%)CBD assessed: (84.3%)CBD lumen measured: (45.7%) In the second cycle (45 patients), adherence improved:Gallbladder neck assessed: (77.8%)Echogenicity of bile reported: (33.3%)Wall thickness commented on: (75.6%)CBD assessed: (97.8%)CBD lumen measured: (44.4%) Conclusion The audit showed a remarkable improvement in adherence to RCR reporting standards for Gallbladder and biliary tree US, particularly in gallbladder neck assessment and CBD evaluation. However, further improvement is needed in documenting bile echogenicity and CBD lumen measurement. Continued monitoring and staff education are essential for sustainable improvement.
