|---|---|---|
1 | 1.5–1.9 times baseline OR ≥ 0.3 mg/dL (≥ 26.5 μmol/L) increase | < 0.5 mL/kg/h for 6–12 h |
2 | 2.0–2.9 times baseline | < 0.5 mL/kg/h for ≥ 12 h |
3 | 3.0 times baseline OR Increase in serum creatinine to ≥ 4.0 mg/dL (≥ 353.6 μmol/L) OR Initiation of renal replacement therapy OR, in patients < 18 years, decrease in eGFR to < 35 mL/min per 1.73 m2 | < 0.3 mL/kg/min for ≥ 24 h OR Anuria ≥ 12 h |
