Key Points Question How has use of computed tomographic angiography (CTA) for suspected gastrointestinal bleeding in the emergency department (ED) increased, and has it led to improved diagnostic detection or possible overuse? Findings In this retrospective cohort study of 954 ED patients from 2017 to 2023, the proportion of total CTA examinations related to gastrointestinal bleeding increased from 0.09% to 0.7%. The test-positive proportion declined from 20.0% to 6.3%. Meaning These findings suggest potential overuse of CTA in the ED setting for suspected gastrointestinal bleeding.
