Improving Barrett's Diagnosis and Surveillance Service at a District General Hospital in the United Kingdom

ABSTRACT

Introduction: Barrett's oesophagus is a well identified precursor for oesophageal adenocarcinoma, with the risk of malignant transformation being 0.5% annually. It is therefore crucial that diagnosis and surveillance standards meet national guidelines. This audit was carried out to assess if our District General Hospital was meeting the standards set by the British Society of Gastroenterology with regards to Barrett's diagnosis and surveillance. Method(s) Data was collected looking at 143 OGDs carried out for Barrett's diagnosis and surveillance at a District General Hospital in the United Kingdom from 01/01/2018 to 30/06/2018. The OGD reports were compared against recommended national standards set by the British Society of Gastroenterology. A proforma was created and was put into use from August 2020. It was utilized by all endoscopists when carrying out OGDs for Barrett's diagnosis and surveillance. The proforma was added to the end of the hospital's standard endoscopy report. Following the intervention and use of the proforma, the second cycle of the audit was carried out looking at 58 OGDs completed between 05/08/2020-27/02/2021 to see if they met the standards set out by the British Society of Gastroenterology. The Barrett's surveillance service and the volume of OGDs carried out following the introduction of the proforma was affected by the Covid-19 pandemic. Result(s) The first cycle of the audit found that only 34% of OGDs had a Prague classification documented correctly. 0% of OGDs had the correct biopsy protocol followed and 12.6% of endoscopies did not have any biopsies taken. 26% of patients had no follow up or surveillance endoscopy interval documented or organised. Following the intervention, it was found that 96% of endoscopies now had a Prague classification documented, an increase of 62%. There was a 65% increase in correct biopsy technique being followed and 100% of OGD reports now had surveillance interval documented if deemed appropriate. Conclusion(s) The audit clearly displays that following our intervention there was a significant improvement in the quality of Barrett's diagnostic and surveillance endoscopies, when compared to national guidelines. Given its potential for malignant transformation, correct surveillance is exceptionally important to improve patient care and reduce mortality. The introduction of a proforma drastically improved the standard of the service provided at our District General Hospital and is one that can be transferable to other hospitals.
