Abstract

Background: Atrial fibrillation (AF) is the most commonly diagnosed arrhythmia inclinical practice, and is associated with a significant medical and economic burden.Anticoagulants reduce the risk of stroke and systemic embolism by approximatelytwo-thirds compared with no therapy. Knowledge regarding anticoagulant therapycan influence treatment outcomes in patients with AF.Objective: To measure the level of anticoagulation knowledge in patients with AF takingoral anticoagulants (OACs), investigate the association between patient-relatedfactors and anticoagulation knowledge, and compare these results in patients takingwarfarin and direct-acting oral anticoagulant (DOACs).Methods: Participants were recruited for an online survey via Facebook. Survey componentsincluded the Anticoagulation Knowledge Tool, the Perception of AnticoagulantTreatment Questionnaires (assessing treatment expectations, convenience and satisfaction),a modified Cancer Information Overload scale and the Morisky MedicationAdherence Scale. Treatment groups were compared and predictors of OAC knowledgewere identified.Results: Participants taking warfarin had a higher knowledge score compared withthose taking DOACs (n = 386, 73% ± 13% vs 66% ± 14%, PConclusion: The study identified knowledge gaps in patients taking OACs, and thesedeficiencies appeared to be greater in participants taking DOACs. Knowledge assessmentshould be integrated into patient counselling sessions to help identify and resolveknowledge deficits.
