AKI Staging (KDIGO 2012)
Stages acute kidney injury (AKI) severity using KDIGO 2012 criteria based on creatinine rise and urine output.
Score interpretation
No AKI criteria met.
→ No AKI criteria met; continue monitoring if at risk.
Stage 1 by the creatinine or the urine output criterion (the higher stage applies).
→ Identify and treat reversible causes; stop nephrotoxins; optimise fluids.
Stage 2 by the creatinine or the urine output criterion (the higher stage applies).
→ Nephrology review; close monitoring; consider renal replacement threshold.
Stage 3 by the creatinine or the urine output criterion, or renal replacement therapy started.
→ Urgent nephrology; renal replacement therapy (CRRT/HD) assessment; ICU level care.
Interpretation bands for the AKI Stage (KDIGO). Apply clinical judgement and local guidance.
