What the engine reports
Detected clinical pattern
Criteria for CKD Met — Classified
Chronicity is documented and the result is classified CKD G3aA2. This is criteria-based status, not a probability.
- Chronicity: Chronicity confirmed (≥3 months)
- CGA: CKD G3aA2
- Pattern: Possible hypertensive kidney disease
Clinical summary
CKD G3aA2: criteria met on documented chronicity (UACR 80 mg/g). Pattern flagged for adjudication: possible hypertensive kidney disease. Priority: complete risk stratification, review etiology and kidney-protective management.
Why this pattern was identified
- Albuminuria. UACR 80 mg/g, category A2 (30–300 mg/g).
- CKD criteria met. CKD G3aA2 on documented chronicity. Criteria-based status, not a probability.
Patterns for physician adjudication
Evidence shown, not scored: pattern weights are not clinically validated.
Possible hypertensive kidney disease pattern
Supporting
- Longstanding hypertension
- Albuminuria A2
- No active urine sediment
Contradicting or missing
- Competing causes not excluded
Recommended next steps
For physician consideration. Urgent review always comes first.
- 1Confirm complete risk stratification (CGA) and review etiology, blood pressure and kidney-protective management.
- 2Monitor eGFR and UACR longitudinally at an interval set by the CGA risk category.
Missing information
- Cystatin C (optional; improves GFR accuracy near decision thresholds).
- Urine sediment / microscopy (supports etiologic adjudication).
Why it matters
CKD with albuminuria and reduced GFR is associated with higher risks of kidney progression and cardiovascular disease, and the CGA category sets monitoring intensity.
Evidence and rule trace · 5 rules
DET-001Kidney abnormality detected
Inputs: UACR 80 mg/g (≥30)
kidney_abnormality_detected: determine chronicity and evaluate acute causes before confirming CKD
CGA-001Assign G category from selected indexed eGFR
Inputs: G category G3a (documented)
G3a (45–59 mL/min/1.73 m²)
CAUSE-002Possible hypertensive kidney disease pattern
Inputs: confirmed CKD · longstanding hypertension · albuminuria A2 · no active urine sediment
possible_hypertensive_kidney_disease: etiology remains provisional; exclude competing causes
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.
