Nudge tool aims to cut unnecessary CT scans for lung clots
NCT ID NCT07249385
First seen Jan 08, 2026 · Last updated Jun 23, 2026 · Updated 22 times
Summary
This study tests a computer tool that gently reminds doctors when they are about to order a CT scan for a possible pulmonary embolism (a blood clot in the lung) against clinical guidelines. The tool only appears when the order may not be needed, giving doctors a chance to reconsider. About 440 healthcare providers across 10 emergency rooms will use the tool, and researchers will track whether it leads to more appropriate CT scan use.
