P12 National endoscopy database (NED): the first million

Introduction The National Endoscopy Database (NED) is populated by data extracted automatically from endoscopy reporting systems (ERSs) of endoscopy services in the UK. 406 out of 520 UK endoscopy sites are currently uploading. We aimed to provide an overview of oesophagogastroduodenoscopies (OGDs) stored on NED. Methods Data from all OGDs uploaded to NED from 2016 to the 28th January 2020 was accessed and analysed using the standard output from the NED website. Results 1,010,741 OGDs have been uploaded to NED. 651,270 of those are from 2019, compared to 281,883 in 2018 and 21,457 in 2017, indicating the ongoing roll-out of NED across the UK. 47% of procedures were performed on male patients, 52% on female and 1% unspecified. 27% of OGDs were performed on patients 13% of procedures were on in-patients, 65% on out-patients, while 22% were unspecified. 51% of procedures were routine, 37% urgent, 3% emergency, and 3% surveillance. 7% were not specified. 49% of procedures were unsedated. The most common indications were: Dyspepsia (17%), Heartburn/Reflux (15%), Anaemia (15%), Dysphagia (14%), Abdominal Pain (12%). Other frequent indications were: Weight Loss (7%), Nausea/Vomiting (6%), Melaena (5%), Haematemesis (3%), Barrett’s Oesophagus (3%), Varices Surveillance (2%). ‘Other’ was included in the indication field in 37% of OGDs. The most common diagnoses were: Normal (31%), Hiatus Hernia (27%), Non-erosive Gastritis (17%), Reflux Oesophagitis (11%). Other frequent diagnoses were: Barrett’s oesophagus (7%), Erosive Gastritis (6%), Gastric Polyp(s) (5%), Non-erosive Duodenitis (5%), Oesophageal Varices (2%), Erosive Duodenitis (2%), Duodenal Ulcer (2%), Gastric Ulcer (2%). ‘Other’ was included in the diagnosis field in 18% of OGDs. (NB: Multiple indications and diagnoses can be entered for a procedure, hence sum of percentages is greater than 100% for these categories) Conclusion The majority of procedures were performed in the ≥ 50 age group, peaking between ages 70 to 79, although a quarter of all procedures were performed in people younger than 50. Close to half of OGDs are performed without sedation. Procedure uploads to the NED continue to increase exponentially year on year. The volume of data and high proportion of sites uploading allows unparalleled insights into OGD practice in the UK.
