Anemia in CKD context without overdiagnosing EPO deficiency
Anemia in CKD context without overdiagnosing EPO deficiency
Purpose: Require workup before causal claim
Inputs the engine received
Patient

- 55 years

- CKD confirmed
- Yes
- G category

Laboratory
- Hemoglobin
- 10.8 g/dL
- MCV
- 89 fL
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)
- Complication: anemia in ckd context
Clinical summary
CKD criteria met on documented chronicity (); classification is incomplete without UACR. Physician adjudication required.
Patterns for physician adjudication
Evidence shown, not scored: pattern weights are not clinically validated.
Possible anemia of CKD context
Supporting
- Hemoglobin 10.8 g/dL
- Confirmed CKD G3b
Contradicting or missing
- Iron studies and other causes not yet evaluated
- MCV 89 fL
Recommended next steps
For physician consideration. Urgent review always comes first.
- 1Evaluate anemia with CBC, reticulocytes, ferritin and TSAT; a renal cause is not assigned before other causes are excluded.
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 · 3 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
confirmed_ckd_incomplete_risk_classification
ANEMIA-001Anemia in CKD screening pattern
Inputs: hemoglobin 10.8 g/dL (<13 for male) · confirmed CKD
anemia_in_ckd_context: evaluate with CBC, reticulocytes, ferritin and TSAT; do not assign a renal cause without excluding others

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.
