The diagnostic criteria of acute kidney injury in cirrhosis

Parameter	Definition
Baseline SCr	Stable SCr ≤3 months
	If not available, a stable SCr closest to the current one
	If no previous SCr at all, use admission SCr
Definition of AKI	↑ in SCr ≥26.5 μmoL/L (0.3 mg/dL) ≤ 48 hours, or ↑ 50% from baseline
Staging	Stage 1 : ↑ SCr ≥26.4 μmoL/L (0.3 mg/dL) or ↑ SCr ≥1.5–2.0 × from baseline
	Stage 2 : ↑ SCr >2.0–3.0 × from baseline
	Stage 3 : ↑ SCr >3.0 × from baseline, or
	SCr ≥352 μmoL/L (4.0 mg/dL) with an acute ↑ of ≥26.4 μmoL/L (0.3 mg/dL), or
	Initiation of renal replacement therapy

SCr, Serum creatinine; AKI, acute kidney injury.
