PRescriptiOn PattERns Of Oral Anticoagulants in Non-valvular Atrial Fibrillation: A Single Center Experience From Turkey (PROPER)

Atrial fibrillation, the most common sustained arrhythmia, is the major cause of acute ischemic stroke. The prognosis of ischemic stroke associated with atrial fibrillation (AF) tends to have a worse prognosis for recovery compared with other ischemic stroke subtypes. The risk of stroke was shown to decline to 68% by oral anticoagulant (OAC) therapy.The investigators have evaluated appropriate use of anticoagulants in non-valvular AF patients. Appropriate use of oral anticoagulants was assessed by Medication Appropriateness Index (MAI). The MAI consists of 10 criteias namely, indication, choice, dosage, modalities and practicability of administration, drug-drug interactions, drug-disease interactions, duplication, duration, and cost-effectiveness. The tenth criteria was not evaluated because of limited data regarding cost-effectiveness of the drugs.
