What the engine reports
Detected clinical pattern
CKD Criteria Met — Classification Incomplete
Chronicity is documented, but the A category (UACR) is missing, so risk classification is incomplete.
- Chronicity: Chronicity confirmed (≥3 months)
Clinical summary
CKD criteria met on documented chronicity (); classification is incomplete without UACR. Physician adjudication required.
Missing information
- UACR (required for the A category and risk assessment).
- UACR (required for the A category, risk assessment and a complete classification).
Why it matters
The result is placed in context so the physician can see what is established, what is provisional and what is missing.
Evidence and rule trace · 2 rules
CGA-001Assign G category from selected indexed eGFR
Inputs: G category G3b (documented)
G3b (30–44 mL/min/1.73 m²)
CGA-005Incomplete classification when UACR absent
Inputs: G3b · UACR missing

Evidence
- R1 · KDIGO 2024 Clinical Practice Guideline for the Evaluation and Management of Chronic Kidney Disease. Kidney Disease: Improving Global Outcomes (KDIGO), 2024.
Physician adjudication required. Clinical decision support for physician review. Criteria-based status is not a probability. Findings require physician adjudication and correlation with the complete clinical context. Validation-only release: not for production clinical use.
