Recognizing ALBI Grade in Child-Pugh A Patients at a Glance: Mathematical Simulation and Large-Scale Clinical...

Area of Science:

• Hepatology
• Clinical Biochemistry
• Medical Informatics

Background:

• The albumin-bilirubin (ALBI) grade assesses hepatic reserve but requires formulaic calculation, limiting bedside application.
• A need exists for simplified ALBI grade assessment for wider clinical adoption.

Purpose of the Study:

• To develop and validate simple cut-off values for the ALBI grade without equation-based calculation.
• To enhance the clinical utility of the ALBI grade for real-world patient management.

Main Methods:

• Mathematical simulation of ALBI grade parameters within the Child-Pugh A classification range.
• Derivation of cut-off points for direct patient stratification.
• Validation using a large, multi-center real-world cohort (Chang Gung Research Database).

Main Results:

• Clinically applicable cut-offs were identified: albumin ≥ 4.4 g/dL or ≤3.5 g/dL, and bilirubin ≥ 2.4 mg/dL, with refinements at albumin 4.0 g/dL and bilirubin ≥ 1.0 mg/dL.
• 82% of 7583 Child-Pugh A patients were directly classifiable without computation.
• Consistent applicability was observed across chronic liver disease and hepatocellular carcinoma (HCC) subgroups, with minimal increase in equation dependence for HCC patients.

Conclusions:

• Simplified ALBI grade cut-off rules, validated in a multi-center cohort, enable rapid assessment in most Child-Pugh A patients.
• This approach improves the clinical usability of the ALBI grade.
• Supports integration into patient care, clinical trials, and treatment allocation decisions.
