Impact of Stress Ulcer Prophylaxis Discontinuation Guidance in Mechanically Ventilated, Critically Ill Patients: A Pre-Post Cohort Study.

Recent data highlight unclear efficacy and potential negative sequelae of stress ulcer prophylaxis (SUP) in the intensive care unit (ICU). Minimizing SUP exposure has pertinent clinical and other implications. This study assessed medication use and clinical outcomes before and after implementation of a practice guideline promoting early discontinuation of SUP in mechanically ventilated ICU patients. Retrospective, single-center, pre-post cohort study within a medical ICU at a large, academic medical center. Adult patients requiring mechanical ventilation and receiving SUP via a histamine-2 receptor antagonist (H2RA) or proton pump inhibitor (PPI) were eligible for inclusion. The clinical practice guideline was implemented on January 1, 2020. The impact of implementation was assessed via percent of patient-days with inappropriate SUP. Incidence of clinically important GI bleed was the primary safety outcome. A total of 137 pre-guideline and 112 post-guideline patients were included. Comorbidity burden was similar between groups. A higher prevalence of baseline vasopressor receipt (39% vs 67%, Implementation of an early SUP discontinuation guideline was associated with significant improvements in SUP prescribing practices. Baseline differences between groups likely explain observed differences in clinical outcomes.
