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 Not assessable

  • 2026-08-04 creatinine 1.4 mg/dL · filtering rate 41.5 (G3b range)
  • 2026-10-03 creatinine 0.9 mg/dL · filtering rate 70.5 (G2 range)
  • 2026-11-12 creatinine 1.3 mg/dL · filtering rate 45.4 (G3a 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 Ferritin Draft · pending review

    Ferritin 11 ug/L on 2026-11-12 09:05 meets the published definition's criteria for the category “band below the ferritin cut-off for this group” (who2020_iron_deficiency_ferritin@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: Not assessable: the data cannot decide not assessable

eGFR 45.4 on 2026-11-12 (lab row L-0021); eGFR 70.5 on 2026-10-03 (lab row L-0020); eGFR 41.5 on 2026-08-04 (lab row L-0019). Not assessable: one value below 60 (eGFR 45.4 on 2026-11-12) since the last value of 60 or more; persistence needs a repeat at least 90 days later. Lookback: every creatinine result on file before this note. Note: a kidney-function statement is present (quoted below); it cannot be checked against these values.

From the draft note: CKD 3b

Both directions
Both directions Not assessable: the data cannot decide (reason above). Nothing is flagged either way.
  • 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)
    1.3 / 0.9 = 1.44x
    Rows: L-0020, L-0021
  • 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 assessable: one value below 60 (eGFR 42.7 on 2026-11-12) since the last value of 60 or more; persistence needs a repeat at least 90 days later
    Rows: L-0019, L-0020, L-0021
  • not met: Two eGFR < 60 at least 90 days apart, none >= 60 between (2021 eGFR equation) (kdigo_ckd_2024@1.1)
    not assessable: one value below 60 (eGFR 45.4 on 2026-11-12) since the last value of 60 or more; persistence needs a repeat at least 90 days later
    Rows: L-0019, L-0020, L-0021
  • 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.
