New Decision-Making tool aims to prevent bleeding in blood thinner users
NCT ID NCT06401863
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a computer tool called DDInteract that helps doctors and patients make safer decisions about blood thinners. The tool calculates a person's risk of bleeding and lets them explore 'what if' scenarios. About 3,700 adults on blood thinners will take part across three U.S. clinics.
