RAPID3 (Routine Assessment of Patient Index Data 3) is a patient-reported questionnaire and scoring system used to quickly estimate rheumatoid arthritis (RA) disease activity and severity. It’s designed to be simple, fast, and entirely based on what the patient reports, without needing joint counts or lab tests.
