🫘 RIFLE AKI Criteria
UseWhen to use: historical RIFLE staging or research comparability when KDIGO is not required.
StrataReport the highest applicable class; prefer KDIGO when institutional policy requires it.
LimitsWhen not to use: unknown baseline without caveat. · Pitfall: mixing RIFLE with KDIGO labels in the same note. · Not a dialysis indication alone.

When to use
When to use: historical RIFLE staging or research comparability when KDIGO is not required.
How it works
R/I/F by Cr fold-change or oliguria; Loss >4 weeks; ESKD >3 months.
Key points
- Risk/Injury/Failure/Loss/ESKD.
- Cr or UO.
- Next: KDIGO / cause.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Baseline creatinine | 70 μmol/L |
|---|---|
| Current creatinine | 160 μmol/L |
| Urine output category | <0.5 mL/kg/h × 6 h (Risk) |
| Complete loss of kidney function >4 weeks | No |
| ESKD >3 months | No |
→RIFLEI — Injury
- Cr ratio：2.29×
- Cr class：Injury
- UO class：Risk
| Baseline creatinine | 70 μmol/L |
|---|---|
| Current creatinine | 160 μmol/L |
| Urine output category | <0.3 mL/kg/h × 24 h or anuria ≥12 h (Failure) |
| Complete loss of kidney function >4 weeks | Yes → Loss |
| ESKD >3 months | Yes → ESKD |
→RIFLEE — ESKD

FAQ
Frequently asked questions
- Does RIFLE AKI Criteria upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is RIFLE AKI Criteria calculated in practice? Can you show a worked example?
- Inputs: Baseline creatinine 70 μmol/L, Current creatinine 160 μmol/L, Urine output category <0.5 mL/kg/h × 6 h (Risk), Complete loss of kidney function >4 weeks No, ESKD >3 months No → Result: RIFLE I — Injury（Cr ratio: 2.29×, Cr class: Injury, UO class: Risk） Inputs: Baseline creatinine 70 μmol/L, Current creatinine 160 μmol/L, Urine output category <0.3 mL/kg/h × 24 h or anuria ≥12 h (Failure), Complete loss of kidney function >4 weeks Yes → Loss, ESKD >3 months Yes → ESKD → Result: RIFLE E — ESKD（Cr ratio: 2.29×, Cr class: Injury, UO class: Failure）
