Atrial Fibrillation

Atrial Fibrillation patient preference study

Trial purpose

The main research question of this patient survey is to assess AF patients’ preferences associated with different attributes which describe the different available anticoagulation treatment options (VKA or NOACs and, in case of NOACs, Apixaban, Dabigatran or Rivaroxaban).
VKA (Waran®) will be 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 Swedish 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
