Question - What is the Kidney Disease Improving Global Outcomes (KDIGO) working group definition of “contrast induced acute kidney injury”?
Answer- The cited article notes The Kidney Disease Improving Global Outcomes (KDIGO) working group proposed the term “contrast- induced acute kidney injury” and suggested a definition based on a plasma creatinine level that has increased by a factor of 1.5 times or more over the baseline value within 7 days after exposure to contrast medium, a plasma creatinine level that has increased by at least 0.3 mg per deciliter (26.5 μmol per liter) over the baseline value within 48 hours after exposure to contrast medium, or a urinary volume of less than 0.5 ml per kilogram of body weight per hour that persists for at least 6 hours after exposure.
