Computer alert aims to stop deadly clots after hospital stay
NCT ID NCT03728166
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a computer alert can help doctors remember to prescribe blood-thinning medicine for high-risk patients after they leave the hospital. Blood clots are a serious risk for some hospitalized patients, even after discharge. The trial will include 400 adults aged 40 or older who are at high risk for clots and are not already on blood thinners. The goal is to see if the alert increases use of preventive medicine and reduces clot-related complications.
