P35 woman, 74 · outpatient visit Clinician-typed

Agrees: nothing to do Kidney results 200 days apart are 60 or above (filtering rate 71.8 on 2026-04-26 and 71.8 on 2026-11-12) and the note doesn't mention kidney function.

The note unsigned draft · Thu Nov 12, 2026 12:00 PM

Chief complaint: fatigue, poor appetite and weight loss.
S: Eating about half of usual meals for six weeks. Tired most afternoons. Seen by the dietitian this week.
O: BP 118/70, HR 84. Weight 63.2 kg. Temporal wasting noted.
A/P:
1. Pancreatic adenocarcinoma on chemotherapy: oncology follow-up next week.
2. Fatigue and poor appetite: oral nutrition supplement twice daily; dietitian follow-up in 2 weeks.
3. Nausea: ondansetron as needed before meals.

Edit note

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 Agrees: nothing to do

2026-04-26 creatinine 0.85 mg/dL · filtering rate 71.8 (G2 range)
2026-11-12 creatinine 0.85 mg/dL · filtering rate 71.8 (G2 range)

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

Kidney filtering rate (eGFR) over time · Read by AI reader and rule reader agree
Nutrition (dietitian's assessment) · Read by AI reader and rule reader agree (openrouter · openai/gpt-6.1-terra, openai/gpt-6.1-terra)

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.

Kidney function (eGFR persistence) · kdigo_ckd_2024@1.1

eGFR: Nothing to review criteria met under 0 of 2 eGFR equations (2021 race-free, 2009)

eGFR 71.8 on 2026-11-12 (lab row L-0083); eGFR 71.8 on 2026-04-26 (lab row L-0082). KDIGO persistence: not met (two values of 60 or more 200 days apart, none below 60 after them). Note: no kidney-function statement found. Nothing to review.

Both directions
What the labs show that the note doesn't say	Criteria not met; nothing unstated
What the note says that the labs don't support	No statement in the note

not met: Urine ACR >= 30 mg/g on two values at least 90 days apart (needed only when eGFR >= 60) (kdigo_ckd_2024@1.1)
no urine ACR on file
met: Latest creatinine below 1.5x the lowest value in the previous 365 days (otherwise: possible acute change; repeat needed) (kdigo_ckd_2024@1.1)
0.85 / 0.85 = 1.0x
Rows: L-0082, L-0083
met: No condition on record that makes the estimating equation unreliable (maintenance dialysis, kidney transplant, pregnancy, limb amputation or another extreme of muscle mass) (kidney_exclusions@1.0)
none on record for this encounter date
not met: Two eGFR < 60 at least 90 days apart, none >= 60 between (2009 eGFR equation) (kdigo_ckd_2024@1.1)
not met: two values of 60 or more 200 days apart, none below 60 after them
Rows: L-0082, L-0083
not met: Two eGFR < 60 at least 90 days apart, none >= 60 between (2021 eGFR equation) (kdigo_ckd_2024@1.1)
not met: two values of 60 or more 200 days apart, none below 60 after them
Rows: L-0082, L-0083
met: Values used are steady-state (local convention: values from an admission meeting the creatinine-change criteria are excluded) (kdigo_ckd_2024@1.1)
no values excluded

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.
