Intensity of Anticoagulation with Warfarin and Risk of Adverse Events in Patients Presenting to the Emergency Department

Abstract

The ability of patients receiving warfarin to maintain an international normalized ratio (INR) within the desired therapeutic range is important for both efficacy and risk of adverse events. It is unclear whether the desired INR is maintained in patients receiving warfarin who present to the emergency department (ED) and whether they have a higher rate of adverse events.
