KDIGO AKI Staging
Stages acute kidney injury severity to guide management and prognosis
- Highest activation tier
- Mandatory
- How it is scored
- Scored in code; a detected disagreeing draft value is flagged for correction
- Care settings
- Emergency department, ICU, Inpatient
When it activates
Scribeable activates a calculator from the encounter. The KDIGO AKI Staging can activate when the transcript or pasted chart context documents any of these:
- Acute kidney injury staging
- Rising creatinine evaluation
- Oliguria workup
- AKI management decision
- Renal replacement therapy consideration
A coded diagnosis can also activate it. ICD-10 prefixes carried by the registry: N17.
Note-type scope: it activates on notes whose subject resolves to nephrology, hospital medicine, critical care. A note that resolves to another subject does not carry it even when the clinician's specialty matches; a note with no resolvable subject (a generic consultation) falls back to the specialty match.
Inputs the note needs
6 inputs. Each is resolved from the transcript, the pasted chart context and charted labs; an input marked "asks you" is requested as a clarification when it is undocumented.
| Input | Type | Unit / options | Guidance |
|---|---|---|---|
| Baseline serum creatinine (mg/dL) | lab | mg/dL | Asked as: “What is the patient's baseline (pre-AKI) creatinine in mg/dL?” |
| Current serum creatinine (mg/dL) | lab | mg/dL | Asked as: “What is the current creatinine in mg/dL?” |
| Absolute creatinine increase within 48 hours (mg/dL)optional | lab | mg/dL | |
| Urine output (mL/kg/hr)optional | lab | mL/kg/h | |
| Duration of reduced urine output (hours)optional | lab | h | |
| Renal replacement therapy initiatedoptional | history |
Scoring
Stage 1: Cr 1.5-1.9× baseline or ≥0.3 increase in 48h, or UO <0.5 mL/kg/h for 6-12h. Stage 2: Cr 2.0-2.9× baseline or UO <0.5 for ≥12h. Stage 3: Cr ≥3× or ≥4.0 or RRT or UO <0.3 for ≥24h or anuria ≥12h. Score 0-3.
Stage from Cr Current serum creatinine (mg/dL) vs baseline Baseline serum creatinine (mg/dL) (1=1.5-1.9× or +0.3 mg/dL in 48h, 2=2.0-2.9×, 3=≥3× or ≥4.0 mg/dL or RRT) or UO Urine output (mL/kg/hr) mL/kg/h for Duration of reduced urine output (hours)h
Interpretation
Stage 0: No AKI. Stage 1: Mild AKI — optimize volume, avoid nephrotoxins, monitor. Stage 2: Moderate AKI — nephrology consultation, close monitoring. Stage 3: Severe AKI — urgent nephrology, consider RRT, ICU-level care.

How Scribeable handles it in the note
When an encounter activates the KDIGO AKI Staging at the mandatory tier, Scribeable resolves its inputs from the transcript, the pasted chart context and any charted labs, and asks you for a missing input you can supply before the note is finalised. Bedside-exam and separately ordered study values are not requested one input at a time; a calculator that carries a combined clarification question may still put that single question to you.
The score is computed in code from the resolved inputs, not recalled by the language model. If the draft states a KDIGO AKI Staging value that disagrees with the computed one, the disagreement is flagged to the second drafting pass, which is instructed to correct the score and its interpretation before you see the note.
Classified as a risk score: activated strictly, by a documented trigger, never by a permissive reading of the encounter.
