Objective: To compare the RIFLE (Risk, Injury, Failure, Loss and End-stage Renal Failure) and AKIN (Acute Kidney Injury Network) criteria for diagnosis of acute kidney injury after coronary artery bypass grafting.
Methods: Retrospective cohort. 169 patients who underwent coronary artery bypass grafting from January 2007 through December 2008 were analyzed. Information was entered into a database and analyzed using STATA 9.0.
Results: Patients' mean age was 63.43 +/- 9.01 years old. Predominantly male patients (66.86%) were studied. Acute Kidney Injury was present in 33.14% by AKIN and in 29.59% by RIFLE. Hemodialysis was required by 3.57% and 4.0% of the patients when AKIN and RIFLE were applied respectively. There was 4.0% and 3.57% mortality of patients with Acute Kidney Injury according to the RIFLE and AKIN criteria, respectively. In 88.76% of the cases, there was good agreement between the two methods in the detection (kappa=0.7380) and stratification (kappa=0.7515) of Acute Kidney Injury.
Conclusion: This study showed that the RIFLE and AKIN criteria have a good agreement in the detection and stratification of acute kidney injury after coronary artery bypass grafting.
