Electronic Health Record Order Entry-Based Interventions in Response to a Global Iodinated Contrast Media Shortage Impact on Contrast-Enhanced CT Uti

This retrospective study at a large multisite health system assessed the impact of electronic health record order entry-based interventions in response to the global contrast media shortage of 2022. These two interventions were 1) an alert about shortages after any contrast-enhanced body CT orders, with recommendations for alternate imaging modalities, and 2) a requirement for referrers to enter detailed clinical information for all contrast-enhanced body CT orders. The study found that these interventions significantly reduced contrast-enhanced CT utilization by influencing ordering clinician behavior and associated clinical practice.
