Contrast-induced nephropathy (CIN) develops in 11% of emergency department patients who undergo contrast-enhanced CT (CECT), according to a study published in the Clinical Journal of the American Society of Nephrology (2009; published online ahead of print).

The incidence is “probably higher than might be predicted for a low-risk, relatively young, ambulatory population,” the authors wrote. CIN was associated with a significantly increased risk of severe renal failure and renal failure as a contributor to death.
