Prognostic impact of deprivation on esophagogastroduodenoscopy outcome.

Socioeconomic deprivation has long been associated with many gastrointestinal diseases, yet its influence on esophagogastroduodenoscopy (EGD) diagnosis has not been evaluated. The aim of this study was to investigate the influence of deprivation on outcomes of EGD irrespective of referral reason. Two thousand consecutive patients presenting to four Health Boards in Wales beginning in June 2019 were studied retrospectively with deprivation scores calculated using the Wales Indices of Multiple Deprivation (WIMD). Patients were subclassified into quintiles for analysis (Q1 most, Q5 least deprived). Inhabitants of the most deprived areas were more likely to be diagnosed with peptic ulcer (Q1 7.9%, Q5 4.7%; odds ratio [OR] 0.498, =0.018), severe esophagitis (LA4, Q1 2.7% v Q5 0%, OR 0.089, 0.002), infection (Q1 5.4%, Q5 1.7%; OR 0.284, =0.002), but less likely to be diagnosed with Barrett's esophagus (Q1 6.3% v Q5 12.3%, OR 2.146, =0.004) than those from the least deprived areas. New cancer diagnoses numbered 53 and were proportionately higher after presentation for urgent suspected cancer (USC, n=35, 4.6%) than for routine referrals (n=3, 0.6%, < 0.001). Deprivation was associated with more advanced stage cancer (stage III Q1 16.7% v Q5 5.6%, OR 0.997, =0.006: stage IV Q1 16.7% v Q2 38.9% v Q5 22.2%, OR 0.998, =0.049). Deprivation was associated with two-fold more peptic ulcer disease, three-fold more infection, and 12-fold more severe esophagitis, and more advanced cancer stage.
