Atrial Fibrillation

Anticoagulation preference by AF patients study

Trial purpose

The main research question of this patient survey is to assess AF (Atrial Fibrillation) patients’ preferences associated with different attributes which describe the different available anticoagulation treatment options (Vitamin K Antagonists [VKA] or New Oral Anticoagulants [NOACs] and, in case of NOACs, Apixaban, Dabigatran, Edoxaban or Rivaroxaban).
VKAs (Marcoumar®, Sintrom ®) will be grouped together and compared to Rivaroxaban.

Key Participants Requirements

Sex

Both

Age

18 - N/A
  • Inclusion criteria for AF patients in both the NOAC and the VKA groups:
    - Patients with a confirmed diagnosis of nonvalvular atrial fibrillation (persistent, paroxysmal, permanent),
    - Age of at least 18 years at time of study inclusion,
    - Generally willingness (informed consent) and ability to fill out a survey on satisfaction with treatment and quality of life, and to conduct a structured phone interview (approx. 20 - 30 min) in German language.
    Additional inclusion criterion for Group 1 (NOAC):
    - Continuous anticoagulation with either Apixaban, or Dabigatran or Rivaroxaban for prevention of Stroke & systemic embolism for at least the previous 3 months.
    Additional inclusion criterion for Group 2 (VKA):
    - Continuous anticoagulation with a VKA for prevention of Stroke & systemic embolism for at least the previous 3 months.

  • Exclusion criteria for both groups:
    - Participation in another study (clinical intervention / observational) within the 3 months prior to enrollment,
    - Interruption of VKA/NOAC therapy of more than 2 weeks (bridging) within the prior 3 months or planned bridging in 4 weeks after study inclusion.

Primary Outcome

  • AF patients`preferences towards anticoagulation treatment with either VKAs or NOACs measured with a DCE (discrete choice experiment) design in a phone interview
    - DCE is based on the following attributes /attribute levels: - Frequency of intake (once/twice daily), - Need of INR monitoring/dose adjustment (yes/no), - Need of bridging (yes/no), - Interactions with food/drugs (yes/no), - Distance to treating physician (1km or 15km).
