LupusDisease activity index

BILAG-2004 / Easy-BILAG

Structured recording of lupus disease activity by organ system using the A–E scheme (intention-to-treat principle). This is a recording aid; the full BILAG-2004 item-level algorithm is not implemented.

For clinicians only. This tool is for healthcare professionals and clinical education only. It does not diagnose, replace clinical judgement, or replace specialist assessment. Any decisions about a patient must be based on full clinical assessment, investigations where appropriate, and current clinical guidelines.

BILAG scoring requires physician judgement and the appropriate BILAG-2004 glossary. Use this page as a structured recording aid only, unless the full item-level algorithm has been medically reviewed for your setting.
