Summary
This pilot study will test a web-based decision aid for Black and White patients with atrial fibrillation who are considering blood thinners to prevent stroke.

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Patient Decision Support Tool (web-based educational material)
What this could lead to
If successful, this tool could help reduce racial disparities in blood thinner use and improve shared decision-making for stroke prevention in atrial fibrillation.
What could go wrong
This is a very small pilot study (40 participants) focused on feasibility, not on proving the tool works. It may not show a clear benefit or be generalizable to other settings.
