Table 1.

Classification and definitions of AKI according to ICA-AKI.

ICA-AKI Stages Serum Creatinine

Stage 1 Increase above 0.3mg/dL or elevation of 1.5 to 2 times baseline value

Stage 2 Increase between twice and three times baseline value

Stage 3 Increase greater than three times baseline value or of over 4mg/dL after an increase of at least 0.5mg/dL or need for dialysis

Progression: moving to greater stage or need for dialysis
Regression: moving into milder stage
Response to treatment:
 Complete: return to creatinine value under 0.3mg/dL of baseline
 Incomplete: regression in ICA-AKI stage or reduction of creatinine value of 0.3mg/dL or more of baseline value
 Absent: no regression of AKI.
