    When to Use
    Pearls/Pitfalls
    Why Use
    • All patients with rheumatoid arthritis.
    • Re-assessing patients after starting a new medication for RA.
    • Assessment of disease activity in rheumatoid arthritis (RA) should be viewed as a dynamic, on-going process; many experts recommend assessing the Clinical Disease Activity Index (CDAI) at every patient visit.
    • Early treatment is important for optimal RA outcomes, and the CDAI can help give a gestalt view of a patient’s disease severity and activity.
    • The CDAI provides an excellent overview of a patient's disease severity (it correlates closely with the SDAI which requires laboratory data) and the DAS-28 (which is a much longer, 28-joint assessment).
    • The CDAI can also help guide therapy based on severity of disease (see “Next Steps”).

    Critical Actions

    Patients with high activity scores should receive early and aggressive RA medications with close follow-up, as attaining low activity or remission-level scores may prevent disease progression and disability.
