Zusammenfassung:Since the introduction of new oral anticoagulants (NOACs), besides vitamin-K antagonists, an additional option for stroke prevention of patients with atrial fibrillation (AF) is available. The objective of this study was to assess AF patients’ preferences with regard to the attributes of these different treatment options. We conducted a multicenter study among randomly selected physicians. Preferences were assessed by computer-assisted telephone interviews. We used a discrete-choice-experiment (DCE) with four convenience-related treatment dependent attributes (need of bridging: yes/no, interactions with food/nutrition: yes/no, need of INR controls/dose adjustment: yes/no; frequency of intake: once/twice daily) and one comparator attribute (distance to practitioner: 15 km). Preferences measured in the interviews were analyzed descriptively and based on a conditional logit regression model. A total of 486 AF patients (age: 73.9 ± 8.2 years; 43.2 % female; mean CHA2DS2-VASc: 3.7 ± 1.6; current medication: 48.1 % rivaroxaban, 51.9 % VKA) could be interviewed. Regardless of type of medication, patients significantly preferred the attribute levels (in order of patients’ importance) “once daily intake” (Level: once = 1 vs. twice = 0; Coefficient = 0.615; p
