New study identifies promising focus areas, informs mitigation strategies for contrast shortage in computed tomography

CT scan

The current shortage of iodinated contrast in the United States due to the COVID-19 related production shutdown in China is causing severe disruptions in patient care. A new Harvey L. Neiman Health Policy Institute study outlines the most frequently used computed tomography (CT) services performed on Medicare beneficiaries as focus areas for mitigation strategies for the greatest overall impact.

The study looked at 9.6 million CTs involving iodinated contrast in the Medicare Physician/Supplier Procedure Summary file, which represents 100% of Medicare Part B claims in 2019—the latest pre-pandemic year of data available. The study found that utilization of contrast enhanced CT was highest in the outpatient hospital and emergency department settings. By body region, utilization was highest for the abdomen/pelvis, particularly in outpatient hospitals and emergency departments, followed next by chest CT. For CT angiography, the highest relative utilization relative to standard CT was of the brain followed by head/neck, and in the emergency department and hospital inpatient settings.

According to lead author Richard Duszak, Jr., MD, Professor and Vice Chair for Health Policy and Practice in the Department of Radiology and Imaging Sciences at Emory University School of Medicine and Neiman HPI Affiliate Senior Research Fellow, “The highlighted site of service and body region differences may help guide the creation of the most impactful teams via multi-disciplinary collaboration to balance mitigation with clinical service needs.”
