Clinical practice of Helicobacter pylori infection management by gastroenterologists in secondary and tertiary hospitals: A stratified sampling cross-sectional survey.

Objective: To investigate the management of Helicobacter pylori (H. pylori) infection by gastroenterologists from secondary and tertiary hospitals in Shandong Province, China, where there is a high prevalence of H. pylori infection.
Methods: A questionnaire-based, stratified sampling survey was conducted from June 1 to August 30, 2021. The ratio of secondary to tertiary hospitals was set at 2:1. An electronic questionnaire was sent to the gastroenterologists via the WeChat platform.
Results: A total of 89.09% (1053/1182) gastroenterologists were included. Overall, 34.19% and 60.59% of gastroenterologists recommended screening for and treating H. pylori infection in patients without any competing factors. The most preferred testing method in secondary and tertiary hospitals was the ¹³ C-urea breath test (53.92% and 80.48%), but the reexamination rate of results close to the cut-off value was low (55.10% and 59.48%). Gastroenterologists preferred bismuth-containing quadruple therapy (secondary and tertiary hospitals: 96.67% and 98.53%), but the antibiotic combination prescribed for patients with penicillin allergy was suboptimal in secondary hospitals. The overall post-treatment follow-up rate was 64.58%, and gastroenterologists in secondary hospitals were more proactive than those in tertiary hospitals (69.41% vs 60.04%, P = 0.001). Less than 80% of gastroenterologists emphasized the importance of post-treatment reexamination to their patients. Only a minority of gastroenterologists in secondary and tertiary hospitals (30.79% and 34.36%) achieved acceptable eradication rates (exceeding 80%).
Conclusions: Deficiencies exist in gastroenterologists from secondary and tertiary hospitals, and the H. pylori eradication rate is relatively low. Training programs for gastroenterologists are warranted to strengthen their comprehension of guidelines.
