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. Adult patients who had a CT of the abdomen performed who had at least 2 creatinine measurements, at least 24 h apart, were included. The maximum increase in creatinine was determined by subtracting the maximal creatinine obtained within 7 days with the initial creatinine. The primary outcome was the development of AKI.
RESULTS: A total of 2168 patients met inclusion criteria (1082 before; 1086 after). There was no significant difference in age, gender, comorbid conditions, disposition, or initial estimated glomerular filtration rate between groups. In the prerationing group, 87.7% of patients received ICM compared to 42.7% after. There was no significant difference in the development of AKI between groups (11.1% vs. 11.0%), including when stratified by baseline renal function and adjusted for age, sex, race, comorbid conditions, and emergency severity index.
CONCLUSIONS: The dramatic reduction in ICM use that resulted from the global shortage was not associated with a change in the incidence of AKI. This reinforces the results of previous studies which have failed to find evidence of a relationship between ICM administration and AKI.
