NCT02746107

Brief Summary

Randomized study concerning the effect of the number of risk diagrams (with treatment +/- without treatment), the period of stroke risk estimation (one year or five years) and the target of prescription (the patient with atrial fibrillation or the physician himself, imagining she/he has atrial fibrillation) on the intention to prescribe or not oral anticoagulation.

Outcome Measures

Primary Outcomes (1)

  • Number of Participants Who Prescribed Oral Anticoagulants (OAC) According to the Number of Decision Aid Diagrams

    after regarding the risk diagram, the physician will decide to prescribe/take or not the treatment

    after seeing the decision aid (5 min)

Other Outcomes (3)

  • Number of Participants Who Prescribed Oral Anticoagulants (OAC) According to the Timeframe for Risk Presentation (1 vs 5 Years)

    5 minutes

  • Number of Participants Who Prescribed Oral Anticoagulants (OAC) According to the Target of Prescription (Patient vs. Physician Himself)

    5 min

  • Number of Participants Who Prescribed Oral Anticoagulants (OAC) According to the CHA2D2s-VASC Risk Score

    5 min

Eligibility Criteria

Age24 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • physicians who prescribe anticoagulant treatment for atrial fibrillation (cardiology, internal medicine, family medicine, hematology) or who deal with patients with stroke (neurology, pathology) or bleeding (gastroenterology)

You may not qualify if:

  • physicians who never prescribe anticoagulant treatments, or do not deal with patients with stroke or bleeding because of anticoagulants

Limitations and Caveats

* prescription was only simulated - not real patients, physicians had to imagine they had atrial fibrillation * results could be different on patients * participants had to decide prescription/not after seeing the risk diagram for only 5 minutes
