City-Hospital Collaboration for Early Detection of Liver Fibrosis in Primary Care: A Secondary Prevention Project in the Grenoble Health Area

Cirrhosis and hepatocellular carcinoma (HCC) are responsible for 25,000 deaths per year in France. The main causes are excessive alcohol consumption, metabolic steatosis, and hepatitis B and C. Fibrosis, classified from F0 (absence of fibrosis) to F4 (cirrhosis), is the sole determinant of liver-related mortality, particularly from stage F3. The incidence of metabolic steatosis is increasing, associated with a rise in mortality from chronic liver diseases (CLD). CLDs, often asymptomatic, are diagnosed late, reducing patient survival. Recommendations exist for the screening of hepatic fibrosis in at-risk patients (alcohol, diabetes, metabolic syndrome). This screening relies on calculating the FIB-4 score (calculated from widely prescribed variables: AST, ALT, platelets, age), followed by Fibroscan® (a non-invasive test for hepatic fibrosis) if FIB-4 \> 1.3.
