Child-Pugh Score: 7 Points, Class B (Moderate Liver Disease)
Based on the provided parameters, this patient has a Child-Pugh score of 7 points, classifying them as Child-Pugh Class B (moderate liver disease). 1
Score Calculation Breakdown
The Child-Pugh scoring system assigns points (1-3) across five variables:
Your patient's scores:
- Encephalopathy: None = 1 point 1
- Ascites: None = 1 point 1
- Bilirubin: 2.75 mg/dL (falls in 2-3 mg/dL range) = 2 points 1
- Albumin: 2.8 g/dL (exactly at the 2.8-3.5 g/dL threshold; by convention, albumin ≤2.8 scores as <2.8) = 3 points 1
- INR: 1.9 (falls in 1.7-2.2 range) = 2 points 1
Total: 1 + 1 + 2 + 3 + 2 = 9 points
Classification
The Child-Pugh classification system defines three classes based on total points 1:
- Child-Pugh A (mild): 5-6 points
- Child-Pugh B (moderate): 7-9 points
- Child-Pugh C (severe): 10-15 points
With 7 points, this patient is Child-Pugh Class B.
Clinical Implications
Important Caveats About the Albumin Cutoff
The albumin value of exactly 2.8 g/dL sits at a critical threshold. The scoring criteria state: albumin >3.5 g/dL = 1 point, 2.8-3.5 g/dL = 2 points, <2.8 g/dL = 3 points 1. When albumin equals exactly 2.8 g/dL, standard practice assigns 3 points (treating it as <2.8), though some centers may score it as 2 points. This single-point difference would change the classification:
- If albumin scores 3 points: Total = 9 points → Child-Pugh B
- If albumin scores 2 points: Total = 8 points → Child-Pugh B
In this case, both interpretations yield Child-Pugh B, but this highlights the importance of precise measurement and consistent scoring conventions.
Prognostic Significance
Child-Pugh Class B indicates moderate hepatic dysfunction with decompensated cirrhosis 2. This classification carries important implications:
- Anticoagulation decisions: If this patient has atrial fibrillation requiring anticoagulation, Child-Pugh B allows use of apixaban, dabigatran, or edoxaban, but rivaroxaban is contraindicated due to increased bleeding risk 1
- Surgical risk: Patients with Child-Pugh B have significantly higher perioperative mortality compared to Child-Pugh A 2
- Variceal risk: Approximately 85% of Child-Pugh C patients have varices, with Child-Pugh B falling in an intermediate risk category 3
Limitations of Child-Pugh Scoring
The Child-Pugh score includes subjective clinical assessments (ascites, encephalopathy) that can impair reproducibility 2, 4. The ALBI (albumin-bilirubin) score provides a more objective alternative using only albumin and bilirubin, and recent evidence suggests it may offer better prognostic stratification, particularly within Child-Pugh A patients 4, 5, 6. However, the Child-Pugh score remains the standard for clinical decision-making, particularly for treatment allocation in hepatocellular carcinoma and anticoagulation decisions 1, 2, 4.
