According to recent guidelines, long-term anticoagulation is recommended for patients with atrial fibrillation (AF) and a risk profile with CHA2DS2-VASc score of 1 or more. Vitamin K antagonists(VAK) and novel oral anticoagulants such as rivaroxaban are current treatment options for AF patients with additional risk factors for stroke. Currently there are only limited information to what extend AF patients prefer one or the other treatment option based on patient relevant characteristics of novel oral anticoagulants vs. VKAs. It is also unknown which of the characteristics influences patient preference most and how this relates to a neutral comparator. Furthermore, an additional unknown factor is also how patient evaluate their current treatment and if this leads to differences among treatment with VKAs and rivaroxaban.

Further study details as provided by Bayer:

Primary Outcome Measures:
  • A prescription of patient preferences pattern including 5 attributes for Discrete-Choice-Experiment(DCE)-design in patients with atrial fibrillation [ Time Frame: Within 1-4 weeks after patient enrollement ] [ Designated as safety issue: No ]
    Attributes and values in relation to the DCE-Choice-Set. The patient will receive a "test card" with the following attributes: bridging of anticoagulation, regular anticoagulation control, limitations to eating behaviour and alcohol consumption, once vs. twice daily intake of medication, neutral comparator for quantification display of preference: distance to therapy practice

  • Patient relevant burden/benefit due to anticoagulation using the ACTS-questionnaire [ Time Frame: At study entry ] [ Designated as safety issue: No ]
