Study Overview

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.

Detailed Description

Objectives:

To answer the questions:

Concerning the decision to prescribe (take) treatment on the basis of a decision aid, are there necessary both diagrams (that with risk without treatment, and that with risk under treatment), or it is enough only the second (risk under treatment, which normally gives all the needed information)?
Concerning the decision to prescribe (take) treatment, is it a difference between the effects of the presentation on decision aid of the risk of stroke for the next 1 year, and the presentation of the estimated risk of stroke for the next 5 years?
Is the decision different if physicians prescribe the anticoagulant treatment to patients, over if they should take it themselves?

Study: 2x3 factorial randomized controlled trial (RCT) for comparison:

Between the decision aid with 2 images (without treatment + with treatment) and the one with 1 image (risk only with treatment)
Between the effect of the presentation of the stroke risk chart for 1 year and the stroke risk chart for 5 years.
The decision to prescribe to patients over the decision to take the treatment themselves.
