Comparison and Utility of Intravenous Iodinated Contrast in Chest, Abdomen, Pelvis Computerized Tomography for Trauma Patients With Blunt Mechanism of Injury Before and After the May 9, 2022 Global Contrast Shortage at a Level II Trauma Center

Intravenous (IV) contrast improves the sensitivity and specificity of injury detection in computerized tomography (CT). Its use is recommended in the workup of trauma patients by the American College of Surgeons and American College of Radiology. On May 9, 2022, the Food and Drug Administration declared a shortage of iodinated contrast due to the COVID-19 pandemic. Although the shortage has ended, the temporary lack of IV contrast forced physicians to be prudent in ordering CT scans with IV contrast. We sought to determine if there was a change in the percentage of CT contrast studies performed during the contrast shortage and if this change affected patient outcomes.
