Kidney disease improving global outcomes criteria for acute kidney injury

Stages for AKI	Criteria
Stage I	Serum creatinine increased by 1.5–1.9 times baseline Serum creatinine increased by ≥0.3 mg/dL Urine output <0.5 mL/kg/h for 6–12 h
Stage II	Serum creatinine increased by 2.0–2.9 times baseline Urine output <0.5 mL/kg/h for ≥12 h
Stage III	Serum creatinine increased by 3.0 times baseline Urine output <0.3 mL/kg/h for≥24 h Increase in serum creatinine to t4.0 mg/dL Initiation of renal replacement therapy eGFR decreased to <35 mL/min/1.73 m2 in patients <18 years Anuria for ≥12 h

AKI: Acute kidney injury, eGFR: Estimated glomerular filtration rate
