N2 - There is an intense debate on whether the RIFLE (R-renal risk, I-injury, F-failure, L-loss of kidney function, E-end-stage renal disease) classification or its recent modification, the Acute Kidney Injury Network definition and classification system should be used to standardize research on acute kidney injury. In this study we compared these classifications with regard to (1) the detection of acute kidney injury, (2) their agreement according to the grading of acute kidney injury across classes, and (3) their prognostic value. Methods: We prospectively enrolled 282 cardiac surgery patients undergoing cardiopulmonary bypass and assigned a RIFLE and Acute Kidney Injury Network class to each patient. The incidence of acute kidney injury and in-hospital mortality across classes was compared by using the ?2 test, and their prognostic value was compared by using the area under the curve receiver-operating characteristic for in-hospital mortality.
