Anticoagulation Algorithm

This algorithm is designed to assist in the anticoagulation management of Atrial Fibrillation (AFib)/Atrial Flutter (AFL) patients in an Emergency Department (ED) or Clinical Decision Unit (CDU).

AFib/AFL patients must be evaluated for stroke risk. Anticoagulation should be initiated for appropriate patients.

Warfarin is a widely used stroke prophylaxis agent. However, when using warfarin, it is often necessary to admit the patient so that parenteral anticoagulation can be initiated and maintained until a therapeutic warfarin level is achieved.

An alternative to warfarin therapy is the non-vitamin-K oral anticoagulants (NOACs). NOACs have a rapid onset and can be used for appropriate AFib/AFL patients allowing the patient to be managed in a typical ED or CDU and thereby possibly avoid hospital admission.
