Sites from the Canadian Early Arthritis Cohort database with at least 40 patients were studied. Comparisons were made among sites in change in 28-joint Disease Activity Score (DAS28), proportion of patients in DAS28 remission, and treatment strategies. Results. The study included 1138 baseline patients at 8 sites, with baseline (SD) age 52 years (16.9); 72% women; 23% erosions; 54% ever smokers; 51% rheumatoid factor-positive; 37% anticitrullinated protein antibody-positive; disease duration 187 (203) days; DAS28 4.5 (1.4). Site had an effect on outcomes when adjusting for confounders. At 6 and 12 months, sites B and H, the 2 largest sites, had the best changes in DAS28 (−1.82 and −2.09, respectively, at 6 mos, and −2.27 for both at 12 mos; p < 0.001). Site H had the most patients in DAS28 remission at 6 months [64.5% compared to other sites that had from 34.1% to 51.7% (p < 0.001)], and at the last followup, sites B and H had the most in remission. Subcutaneous methotrexate was used more overall and earlier at sites B and H. Those sites used less steroid therapy, and site B had the second-highest use of triple disease-modifying antirheumatic drugs at any visit. Medications were increased more in 2 of the 3 smallest sites. Biologics were used by 9 months most in the smallest (50.0%) and then largest (19.6%) sites. Conclusion. Sites in an early inflammatory arthritis cohort yielded different outcomes. Better outcomes up to 12 months may result from initial treatment with early combination therapy and/or subcutaneous methotrexate.
