P34 man, 66 · outpatient visit Clinician-typed

Open in the chart

Needs a look The note says CKD; the note does not give a stage. Two results 110 days apart are in the G3b range (filtering rate 38.4 on 2026-07-25 and 37.0 on 2026-11-12).

The results

The note is compared with the patient's own measurements, in both directions. Kidney filtering rate (eGFR) is estimated from creatinine, age and sex.

Kidney filtering rate (eGFR) over time Needs a look

  • 2026-07-25 creatinine 1.9 mg/dL · filtering rate 38.4 (G3b range)
  • 2026-11-12 creatinine 1.96 mg/dL · filtering rate 37.0 (G3b range)

Threshold: filtering rate below 60 on two results at least 90 days apart, none of 60 or more between them.

The AI reader only proposes quoted statements; the rule reader must agree or the topic says "read this part yourself". The results never depend on either reader.

Your decision: Kidney function (eGFR persistence)

Mode: measurements only (no diagnosis is named). The check runs the same way on clinician-typed and AI-drafted notes (as declared by the source system).

Kidney function (eGFR persistence) · kdigo_ckd_2024@1.1

eGFR: Stage in the note differs from the computed category criteria met under 2 of 2 eGFR equations (2021 race-free, 2009)

eGFR 37.0 on 2026-11-12 (lab row L-0080) and eGFR 38.4 on 2026-07-25 (lab row L-0078), 110 days apart, no value >= 60 between. KDIGO persistence: met. Persistent GFR category G3b (the range both values meet). Note: the kidney-function statement (quoted below) gives no stage.

What the note says that the labs don't support Statement present; its stage is missing or differs from the computed category

Creatinine change during this admission · kdigo_aki_2012@1.1

Creatinine change: Does not apply to this visit

Not assessed: outpatient visit: the creatinine-change check runs on inpatient encounters only.

Try one creatinine value

One value is never a confirmed stage: the persistence rule needs a repeat at least 90 days later.
