RIFLE criteria for acute kidney injury in the intensive care units

Abstract

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.
