RIFLE criteria for acute kidney injury in the intensive care units

BACKGROUND Acute kidney injury (AKI) is commonly occurred in intensive care unit (ICU) patients. The aim of the study was a comparison of RIFLE (Risk of renal injury/Injury to the kidney/Failure of kidney function/Loss of kidney function/End stage disease) classification with other scoring systems in the evaluation of AKI in ICUs. MATERIALS AND METHODS We performed a retrospective study on 409 ICU patients who were admitted during the 5 years period. RESULTS At the 1(st) day of admission and time of discharge, the total and non-renal Acute Physiology and Chronic Health Evaluation II and sequential organ failure assessment scores were compared to max RIFLE criteria. In this assessment, there was concordance among the results (P < 0.05). CONCLUSION The RIFLE classification can be used for detection of AKI in ICU patients.
