Open in the chart

Agrees Kidney results 270 days apart are 60 or above (filtering rate 96.4 on 2026-01-14 and 73.1 on 2026-10-11) and the note doesn't mention kidney function.

The note unsigned draft · Wed Nov 11, 2026 09:00 AM

Hospital day 2 progress note.
S: Poor oral intake for 4 days before admission with vomiting. Nausea improving.
O: BP 108/64, HR 96. Dry mucous membranes. Creatinine up overnight.
A/P:
1. AKI, likely prerenal: IV fluids, hold lisinopril, strict intake and output, repeat labs in the morning.
2. Gastroenteritis: antiemetics, advance diet.

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 function over time Agrees

  • 2026-01-14 creatinine 0.8 mg/dL · filtering rate 96.4 (G1 range)
  • 2026-10-11 creatinine 1.1 mg/dL · filtering rate 73.1 (G2 range)

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

Creatinine change during this stay Agrees

The note says AKI and creatinine supports it: it rose by 0.7 mg/dL within 22 hours (peak 2.3 mg/dL).

  • before this stay lowest earlier creatinine 0.8 mg/dL
  • 2026-11-10 08:00 creatinine 1.6 mg/dL (first in this stay)
  • 2026-11-11 06:00 creatinine 2.3 mg/dL (highest)

Threshold: creatinine up by 0.3 mg/dL within 48 hours, or to 1.5 times an earlier value. Urine output is not checked.

Other measurements checked against published definitions

Each definition is a draft pending clinical and coding review unless marked reviewed. You decide what the note says.

  1. Needs a look Sodium Draft · pending review

    Sodium 131 mmol/L on 2026-11-11 06:00 meets the published definition's criteria for the category “below 135 mmol/L” (ese2014_hyponatraemia@1.0). The note doesn't mention this.

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 73.1 on 2026-10-11 (lab row L-0030); eGFR 82.0 on 2026-07-13 (lab row L-0029); eGFR 96.4 on 2026-01-14 (lab row L-0028). KDIGO persistence: not met (two values of 60 or more 270 days apart, none below 60 after them). Note: no kidney-function statement found. Nothing to review.

Try one creatinine value

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