Trends in Use of Diagnostic Imaging for Abdominal Pain in U.S. Emergency Departments.
OBJECTIVE. CT has excellent accuracy for appendicitis but is associated with risks. Research and educational campaigns have been conducted to implement an ultrasound-first strategy for children but not for adults. ⋯ CONCLUSION. CT use has decreased in the evaluation of abdominal pain in children, perhaps because of research findings and efforts to implement an ultrasound-first strategy for suspected appendicitis. In contrast, CT use has continued to increase among adults with abdominal pain in EDs.
