Low adherence to Helicobacter pylori testing in hospitalized patients with bleeding peptic ulcer disease.

BACKGROUND

Helicobacter pylori (H. pylori) testing in patients with bleeding ulcers is recommended by society guidelines and considered a quality indicator. The aim of the study is to examine the proportion of patients with bleeding ulcers who had H. pylori testing and identify predictors associated with H. pylori testing.

MATERIALS AND

METHODS

Consecutive hospitalized patients with bleeding ulcers documented endoscopically at a single center from 10/2004-5/2011 were identified retrospectively from an endoscopy database. The proportion of patients undergoing direct H. pylori testing (histology, rapid urease test, breath test or stool antigen) and any H. pylori testing (direct or serologic) were determined.

RESULTS

Among 330 patients with bleeding ulcers, 105 (32%, 95% CI 27-37%) underwent direct testing and another 52 (16%, 95% CI 12-20%) had serologic testing during a median follow-up of 9 months (range, 0-86). H. pylori testing occurred at the index hospitalization in 146 (93%) of the 157 patients tested. Among the 105 patients who had direct H. pylori testing, 90 (86%) had biopsy-based testing during the initial endoscopy. On multivariate analysis, undergoing biopsy of a gastric ulcer was strongly associated with having direct H. pylori testing performed (OR = 5.1, 95% CI 2.3-11.5; p < .0001).

CONCLUSIONS

Among patients hospitalized with bleeding ulcers, less than half received H. pylori testing and less than a third received the more accurate direct testing. Most of the direct H. pylori testing was biopsy-based with very few being tested after the index hospitalization. Efforts to increase H. pylori testing in patients with bleeding ulcers are needed to improve outcomes.
