- Why not executable
- Executable already, outside this library: apps/exactdx/rules/kidney (kdigo_aki_2012, kdigo_ckd_2024 with the CKD-EPI equations). Not duplicated here. The rule files keep their own citations until their next version; the permissive sources for them are recorded here and in docs/LIBRARY.md (front conditions).
VA/DoD Clinical Practice Guideline for the Primary Care Management of Chronic Kidney Disease, Provider Summary
kdigo_aki_ckdIn our words: CKD: eGFR below 60, or urine albumin-to-creatinine ratio 30 mg/g or higher, on tests at least 3 months apart. eGFR from the 2021 race-free creatinine equation. AKI: creatinine up at least 0.3 mg/dL in 48 hours, or to at least 1.5 times baseline within 7 days, or low urine output for 6 hours.
Decreased eGFR <60 mL/min/1.73 m2 (GFR categories G3a-G5) for ≥3 months | Albuminuria (UACR ≥30 mg/g) on at least two measurements separated by ≥3 months
