Risk of Lower Gastrointestinal Bleeding in Nonsteroidal Anti-inflammatory Drug (NSAID) and Proton Pump Inhibitor Users Compared with NSAID-Only Users: A Common Data Model Analysis.

ABSTRACT:

Background/aims

Recent studies have shown an increased risk of lower gastrointestinal bleeding in patients who use both nonsteroidal anti-inflammatory drugs (NSAIDs) and proton pump inhibitors (PPIs). We analyzed the risk of lower gastrointestinal bleeding and compared this risk between NSAID+PPI users and NSAID-only users.

Methods

In this retrospective, observational study, data from five hospitals were analyzed using a common data model to determine the risk of lower gastrointestinal bleeding and compare this risk between NSAID+PPI users (target cohort) and NSAID-only users (comparative cohort). Cox proportional hazard models and the Kaplan-Meier estimations were employed after extensive propensity score matching.

Results

Among 24,530 individuals in the target cohor
