Common questions
What does Acute Kidney Injury AKI Staging (KDIGO) do?
Use to assign an AKI stage (taking the higher of the creatinine and urine-output criteria) and to anchor the management approach.
How is the result calculated?
Stage 1: SCr 1.5–1.9× or rise ≥ 26.5 μmol/L, UO < 0.5 × 6–12 h. Stage 2: SCr 2.0–2.9×, UO < 0.5 × ≥ 12 h. Stage 3: SCr ≥ 3.0× or ≥ 353.6 μmol/L or RRT, UO < 0.3 × ≥ 24 h or anuria ≥ 12 h. Stage = max(creatinine, urine output).
Is this a substitute for clinical judgement?
No. All results are decision-support only, for licensed clinicians. They must be individualized to the whole patient and the latest guideline version.
