A standardized protocol improves testing rates for Helicobacter Pylori among inpatients with peptic ulcer disease.

BACKGROUND

Despite a strong link between Helicobacter Pylori infection and peptic ulcer disease (PUD), rates of testing for H. Pylori in hospitalized patients with PUD remain largely unexplored. We aimed to determine H. Pylori testing practices at our institution among inpatients with PUD, and to implement a protocol to improve testing rates.

MATERIALS AND METHODS

In this quality improvement initiative, baseline H. Pylori testing practices were determined by analysis of historical data on 100 subsequent inpatients with PUD from January 2016 to June 2017 at a tertiary care hospital undergoing esophagogastroduodenoscopy (EGD). Subsequently, a division-wide testing protocol was implemented, and data were analyzed from 43 consecutive inpatients with PUD from October 2019-March 2020 to determine the protocol's effects.

RESULTS

The analysis of baseline testing practices showed a 57% testing rate for H. Pylori. Gastric biopsies were less likely to be performed during EGDs done outside the endoscopy unit (5.9% vs 32.7%, P = 0.001), outside of usual business hours (6.7% vs 24.3%, P = 0.04), and in cases where endoscopic therapy was administered (6% vs 32%, P = 0.02). After implementation of the new division-wide testing protocol, testing rates increased to 93% (P < 0.001).

CONCLUSIONS

Low baseline inpatient testing for H. Pylori represents a missed opportunity to test a substantial number of high-risk patients with PUD. Implementation of a conceptually simple protocol aimed at increasing rates of gastric biopsy significantly improved testing rates in a prospective follow-up. Widespread standardization of H. Pylori testing for inpatients with PUD may improve important patient outcomes related to complicated PUD.
