Summary

This study tests a decision aid for people who have had a first blood clot and must decide whether to stop or continue blood thinners after at least 3 months of treatment. The aid provides balanced information on risks and benefits and helps clarify personal values. Researchers will measure whether it reduces confusion and improves knowledge in 850 participants across 12 Canadian clinics.

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 aid (behavioural intervention)
What this could lead to: If successful, this decision aid could help patients and doctors make more informed, values-based choices about blood thinner use after a first blood clot.
What could go wrong: This is a behavioural study, not a drug trial, so it won't directly treat or cure the condition. The aid may not change outcomes like clot recurrence or bleeding.
