The Effect of Contrast Rationing on the Development of Acute Kidney Injury During the Global Contrast Shortage.

Background: In April of 2022, the COVID-19 pandemic resulted in a global shortage of intravenous contrast media (ICM), which led our health care system to implement rationing measures.

Study Objectives: We set out to determine if the reduction in ICM use was associated with a change in the incidence of acute kidney injury (AKI).

Methods: We conducted a multicenter retrospective cohort analysis to compare the incidence of AKI in patients who presented before and after ICM rationing.
