Using Evidence-Based Criteria to Decrease CT Utilization for Liver Imaging.

Purpose: Overutilization of imaging in radiology increases costs without improvement in patient outcomes. As a part of the regular quality measures, the Centers for Medicare and Medicaid Services deemed our institution to be overutilizing abdomen and abdominopelvic computer tomography (CT) with and without intravenous (IV) contrast. We implemented a quality improvement (QI) effort to reduce use of abdomen CT with and without IV contrast.
