NotesMETAVIR

NotesMETAVIR is a data concept used to represent notes and metadata linked to METAVIR liver fibrosis assessments. METAVIR is a widely used scoring system for chronic liver disease, particularly hepatitis C, that assigns a fibrosis stage from F0 to F4 and an activity grade from A0 to A3 based on histological evaluation.

NotesMETAVIR may appear as free-text notes or as structured metadata accompanying METAVIR scores in pathology reports, electronic health records, or research datasets. Typical content includes the biopsy date, tissue source and sampling method, the pathologist or reviewer, the exact fibrosis and activity scores, and annotations about discordance, sampling limitations, or additional histological features such as portal inflammation or steatosis. Because the term is not standardized across institutions, the exact fields and terminology can vary, leading to inconsistencies in data capture and interpretation.

In research and clinical data management, NotesMETAVIR provides contextual information that supports audit trails, secondary analyses, and the development of predictive models. It can help document reasons for score disagreements, quality of specimen, and other factors that influence interpretation. Privacy and data governance are important considerations, as notes may contain protected health information; appropriate de-identification and compliance with applicable regulations are essential.

Overall, NotesMETAVIR serves as a complementary data construct to METAVIR scores, enriching datasets with contextual notes while highlighting the need for standardization and careful data handling. See also METAVIR scoring system.
