Assessing guideline adherence in patients with non-variceal upper gastrointestinal bleeding receiving antiplatelet and anticoagulant therapy

Background & aims: Non-variceal upper gastrointestinal bleeding (NVUGIB) occurs frequently and is associated with a significant morbidity and mortality, especially in patients receiving antiplatelet or anticoagulant therapy (APT and ACT, respectively). We aimed to evaluate adherence to guideline recommendations published by European Society of Gastrointestinal Endoscopy (ESGE).Methods: Retrospective analysis of patients with NVUGIB und prior exposition to APT or ACT at a single university hospital between 01 January 2016 and 31 December 2017.Results: 270 patients were identified (70.4% male, median age 72 years). 6/17 (35.3%) patients receiving APT for primary cardiovascular prophylaxis, 39/71 (54.9%) and 35 (49.3%) patients receiving APT for secondary cardiovascular prophylaxis (using strict and liberal definition, respectively) and 13/25 (52%) patients receiving dual antiplatelet therapy (DAPT) were not managed according to current recommendations. Management of ACT for secondary thromboembolic prophylaxis did not follow guideline recommendations in 59/93 (63.4%) and 34/93 (36.6%) patients (using strict and liberal definition, respectively). 23.7% of patients with NVUGIB were exposed to combined APT and ACT for whom no guideline recommendations exist. Mortality for any reason was twice as high in patients who were not managed according to guideline recommendations (18.8% vs. 8% using strict definition, 20.5% vs. 10.2% using liberal definition), which did not remain significant after adjusting for comorbidities, whereas cardiovascular events were observed at similar rates.Conclusion: A significant number of patients with NVUGIB receiving APT or ACT is not managed according to current ESGE guideline recommendations. Strategies to implement these guidelines into daily practice need to be developed.
