Do novel definitions of Acute Kidney Injury (RIFLE, AKIN, and KDIGO) improve the prediction of adverse events at 30 days and 1 year compared to traditional definitions in patients admitted for acute decompensated heart failure?
Newer AKI classification systems (RIFLE, AKIN, KDIGO) provide only marginal differences in predictive ability for adverse events compared to traditional definitions in acute decompensated heart failure.
During admission for HF, the benefits of using newer AKI classification systems (RIFLE, AKIN, KDIGO) lie with the ability to identify those patients with more severe degrees of AKI who will go on to experience adverse events at 30 days and 1 year. The differences in terms of predictive abilities were only marginal.
