2010 ACR/EULAR Classification Criteria for RA

2010 ACR/EULAR criteria for classifying definite rheumatoid arthritis. Score ≥ 6/10 = definite RA. Applicable to patients with ≥ 1 joint with clinical synovitis not better explained by another diagnosis.

Score interpretation

Not Classified as RA 0–5

Score < 6: Does not meet 2010 criteria for definite RA at this time.

→ Consider undifferentiated inflammatory arthritis. Monitor — early RA may not initially meet criteria. Repeat serology in 6–12 weeks. DMARD therapy may still be appropriate if clinical diagnosis made. Rheumatology referral (NICE: within 3 working days if ≥ 3 joints or metacarpophalangeal squeeze tenderness).

Definite RA — Classify and Treat 6–10

Score ≥ 6: Meets 2010 ACR/EULAR criteria for definite RA.

→ Initiate csDMARD: methotrexate (first-line, 15–25 mg/week with folic acid 5 mg once weekly). Hydroxychloroquine ± sulfasalazine as combination or if MTX not tolerated. Short-course prednisolone bridge 7.5–10 mg/day tapering over 6 weeks. Treat-to-target: DAS28 < 2.6 (remission) or < 3.2 (low disease activity) within 6 months. Anti-TNF / biologic if inadequate response to ≥ 2 csDMARDs. NICE NG100.
