143 Evaluation of Antithrombotic Use in Patients Presenting to the Emergency Department with a Gastrointestinal Bleed

Introduction: As the number of patients on antithrombotic therapy (AT) continues to rise, so does the number of associated adverse events. While many of these events are iatrogenic, an estimated 10-30% are associated with inappropriate prescribing, off label dosing, and failure to manage high-risk interactions. The purpose of this study is to identify opportunities for AT stewardship in patients presenting to the emergency department (ED) with gastrointestinal bleeding (GIB).
