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.

Creatinine change during this stay Needs a look

  • before this stay lowest earlier creatinine 1.75 mg/dL
  • 2026-11-11 10:00 creatinine 1.8 mg/dL (first in this stay)
  • 2026-11-12 07:00 creatinine 3.9 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.

Kidney function over time Agrees

The note says CKD 3b and two results 100 days apart agree (G3b range, filtering rate 40.6 on 2026-04-25 and 39.3 on 2026-08-03).

  • 2026-04-25 creatinine 1.75 mg/dL · filtering rate 40.6 (G3b range)
  • 2026-08-03 creatinine 1.8 mg/dL · filtering rate 39.3 (G3b range)

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

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 Low glucose values Draft · pending review

    Glucose 62 mg/dL on 2026-11-12 06:00 meets the published definition's criteria for the category “level 1 (glucose 54 to below 70 mg/dL)” (ada2026_hypoglycaemia@1.0). The note doesn't mention this.

    Published bodies disagree on these thresholds; another definition may give a different answer.

Kidney function (eGFR persistence) · kdigo_ckd_2024@1.1

eGFR: Note and criteria agree criteria met under 2 of 2 eGFR equations (2021 race-free, 2009)

eGFR 39.3 on 2026-08-03 (lab row L-0036) and eGFR 40.6 on 2026-04-25 (lab row L-0035), 100 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) agrees with the persistent GFR category.

Try one creatinine value

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