AB061. SOH24AB₀51. A closed-loop audit of adherence to recommended surveillance of non-dysplastic Barrett’s oesophagus in Portiuncula University Hospital

Background: Barrett's oesophagus (BO) is a pre-malignant condition whereby the normal stratified squamous epithelium of the distal oesophagus is replaced by metaplastic columnar epithelium. The British Society of Gastroenterology (BSG) 2014 guidelines recommend specific surveillance intervals and a standardised reporting approach to BO using a minimum dataset during oesophagogastroduodenoscopy (OGD). The objective of this study was to the assess the adherence of endoscopists to these guidelines and promote a standardised approach to BO reporting and surveillance. Methods: To assess adherence, a retrospective closed-loop audit was carried out. Audit cycle 1 included patients who had undergone surveillance OGD for BO during 2021. An educational intervention for endoscopists and a proforma for reference during OGD were implemented thereafter. Cycle 2 audited the same parameters post-intervention, from January to July 2023. Results from both were analysed and compared. Results: A total of 50 patients were included in cycle 1, and 44 patients in cycle 2. Both cycles demonstrated high levels of adherence the recommended surveillance intervals (89% and 88.9% respectively). Adherence to the Seattle protocol and measurement of hiatus hernia size increased in cycle 2, while adherence to the Prague criteria remained low (20% versus 22.7%). Paris classification was not reported during either cycle. Conclusions: There is a need for further intervention to increase the standard of BO reporting, namely the Prague criteria for reporting BO extent and Paris classification for classifying visual lesions. Future plans may comprise of focused local proforma development including expansion to include the computer-based platform on which OGD reports are generated.
