NCT ID NCT04956978
First seen Jun 24, 2026 · Last updated Sep 10, 2026 · Updated 3 times
Summary
This pilot study tests a web-based decision aid for Black and White patients with atrial fibrillation who need to choose whether to take blood thinners to prevent strokes. The tool explains risks and benefits and asks about personal preferences. The study will check if the tool is easy to use and acceptable, and whether it helps more Black patients start blood thinners.
What this could mean
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 gaps in blood thinner use for atrial fibrillation, improving stroke prevention in Black patients.
- What could go wrong
- This is a very small pilot study (40 people) focused on feasibility, not effectiveness. The tool may not change actual prescribing or outcomes.
