which patients were using an oral anticoagulant rose from 2.05 million to 2.83 million per quarter (
<0.001), with DOACs accounting for 38.2% of the total in 2014. Visits involving patients with atrial fibrillation using anticoagulants rose from 51.9% in 2009 to 66.9% in 2014. In 2014, rivaroxaban was the most commonly
prescribed DOAC for atrial fibrillation (47.9% of total visits), followed by apixaban (26.5%) and dabigatran (25.5%). Edoxaban had not yet been introduced.
