Summary

This study tests a 'nudge' program—including text reminders, a medication calendar, and an action plan—to help 84 adults with atrial fibrillation take their blood thinners consistently. Participants will watch an educational video, create a daily pill-taking routine, and receive fewer texts over 8 weeks. The goal is to see if these simple prompts improve adherence and reduce stroke risk.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: nudge intervention (educational video, action plan, medication calendar, SMS reminders, feedback messages, telephone call)
What this could lead to: If it works, this could offer a simple, low-cost way to help people with atrial fibrillation stick to their blood thinner medication, reducing stroke risk.
What could go wrong: This is a small, early-stage trial with only 84 participants. The intervention is behavioral, so results may vary widely and may not apply to everyone. It does not test a new drug or cure.
