Patients were surveyed at the baseline and 6-month follow-up clinic visits using Likert scales.Results Among 1004 baseline survey responses, patients’ confidence in their understanding of rhythm control, ablation, anticoagulation and cardioversion was suboptimal, with ‘high’ understanding ranging from 8.5% for left atrial appendage closure to 71.3% for rhythm therapy. Of medical history and demographic factors, education level was the strongest predictor of reporting ‘high’ disease understanding. Among the 786 patients with 6-month survey data, significant increases in the proportion reporting high understanding were observed (p<0.05) only for warfarin and direct oral anticoagulants (DOACs). With the exception of ablation, high understanding for a given therapeutic option was not associated with increased use of that therapy at 6 months.Conclusions About half of patients with new-onset AF understood the benefits of oral anticoagulant at the time of diagnosis and understanding improved over the first 6 months. However, understanding of AF treatment remains suboptimal at 6 months. Our results suggest a need for ongoing patient education.Clinical trial registration Clinicaltrials.gov. Identifier: NCT01701817.
