Thorough evaluation for the new acute kidney injury criteria by Kidney Disease Improving Global Outcomes

Two previous classifications of acute kidney injury (AKI) that are known as RIFLE criteria and AKIN criteria have shown that AKI is associated with increased morbidity and mortality. Differences in predicting ability for prognosis, however, have been reported. In 2012, Kidney Disease Improving Global Outcomes (KDIGO) created the new AKI criteria, combining RIFLE and AKIN criteria. However, such a combination might cause inconsistency among each definition in the criteria. We have investigated all of the definitions in the new KDIGO criteria in detail.
