Figure 1. The Renal Angina Index.

Figure 1

The index calculation for the fulfillment of renal angina is assessed 12 hours after a patient is admitted to the intensive care unit and used for prediction of severe AKI 72 hours (3 days) later. Risk factors are determined as described and assigned a point value (1, 3, and 5). Mechanical ventilation and vasoactive support should be used within the 12-hour time point but are not required to be simultaneously for a patient to be categorized as a “5”. Injury strata are described and assigned to a patient as appropriate. The index is a multiplication of the risk and injury scores assigned. SCr = serum creatinine/baseline = relationship to baseline serum creatinine, %FO = % fluid overload as described previously.27
