An International Multicenter Clustered Randomized Controlled Trial to imProve Treatment With AntiCoagulanTs in Patients With Atrial Fibrillation.

To determine whether a comprehensive evaluation and customized multilevel educational interventions will increase the rate of use of oral anticoagulants and the adherence and persistence of use in patients with atrial fibrillation. Our hypothesis is that there will be differences in the use of oral anticoagulants and the persistence in patients between the control and interventional group. There will be a greater change in the use of oral anticoagulants over one year in the cohort in the intervention sites than the control sites. This will be due to two factors: greater initiation of oral anticoagulants among patients not treated at baseline and greater persistence of treatment for those on treatment at baseline
