title: Use interventions, curb unnecessary imaging.
abstract: A new study shows that ED patients have more confidence in their medical evaluation when a CT study is included but that they have scant understanding of the radiation exposure. Patient-focused education could be effective at curbing unnecessary use of imaging as well as the pressure clinicians might feel to order such studies. Study findings show that patients routinely underestimate the amount of radiation that is associated with CT scans and that many patients have a poor recollection of their imaging history. Consumer-focused interventions prompt patients to track their own imaging history on cards that they carry with them. Radiology and technologist champions can help implement safety precautions that minimize radiation exposure.
