What is the Maddrey's Discriminant Function & Lille Model (Alcoholic Hepatitis)?
The Maddrey's Discriminant Function & Lille Model (Alcoholic Hepatitis) is an evidence-based clinical decision rule engineered to quantify diagnostic probability, stratify clinical severity, and guide therapeutic decision-making in gastroenterology & hepatology practice. Implements the Maddrey Discriminant Function (mDF) and Lille Model response evaluation to identify severe alcohol-associated hepatitis, predict 30-day mortality (~35-50%), and guide 28-day oral prednisolone therapy vs early discontinuation. Clinical scoring tools like Maddrey's Discriminant Function & Lille Model (Alcoholic Hepatitis) are essential in acute and outpatient management, enabling clinicians to objectively differentiate between low-risk candidates suitable for conservative therapy and high-risk patients requiring urgent interventions. Verified against current 2026 clinical standards, this tool is extensively tested on Gulf health authority licensing exams including DHA (Dubai), SMLE (Saudi Arabia), MOH, HAAD/DOH (Abu Dhabi), OMSB (Oman), and QCHP (Qatar).
💡Clinical Pearls & Diagnostic Utility
Pivotal clinical decision rule that identifies patients with life-threatening alcoholic hepatitis who derive clear survival benefit from corticosteroid therapy.
Formula & Calculation Parameters
The mathematical equation and clinical variables required to calculate Maddrey's Discriminant Function & Lille Model (Alcoholic Hepatitis):
Score Interpretation & Clinical Stratification
| Score Range | Clinical Interpretation | Risk Tier |
|---|---|---|
| ≤ 31.9 | Mild-to-Moderate Alcoholic Hepatitis (mDF < 32 / Low 30-Day Mortality) | green |
| 32 – 54 | Severe Alcoholic Hepatitis (mDF 32 - 54 / Corticosteroids Indicated) | yellow |
| ≥ 54.1 | Very Severe Alcoholic Hepatitis (mDF > 54 / High 30-Day Mortality ~50%) | red |
When to Exercise Caution
Laboratory PT variation between reagents requires using exact control PT from the same testing laboratory.
