Patients seen for standard rheumatoid arthritis care have significantly better articular, radiographic, laboratory, and functional status in 2000 than in 1985

Objective. A comprehensive quantitative analysis of measures of disease activity and joint damage has not been available to compare patients in different eras in the same clinical setting. This study was undertaken to determine whether the clinical status of patients with rheumatoid arthritis (RA) has improved on average in recent years. Methods. A quantitative cross-sectional evaluation, which included joint count, radiographic, laboratory, patient questionnaire, and physical function measures, and therapies, was performed in 125 consecutive RA patients seen from 1984 through 1986 ("1985 cohort"). A virtually identical assessment was performed in 150 patients seen from 1999 through 2001 ("2000 cohort"), in the same weekly academic clinic. Measures were compared using descriptive statistics and a median regression model, adjusted for age, duration of disease, level of formal education, and rheumatoid factor. Results. Patients in 1985 had significantly poorer status compared with those in 2000: median 12 versus 5 swollen joints, Larsen radiographic score 20 versus 3, erythrocyte sedimentation rate 33 mm/hour versus 20, and modified Health Assessment Questionnaire 1.0 versus 0.4 (P < 0.019). Severe Disease Activity Scores > 5.1 were seen in 69% of 1985 patients, compared with 30% in 2000. Methotrexate was taken by 10% of patients in 1985, versus 76% in 2000. The proportion of patients not taking any disease-modifying antirheumatic drugs was 66% in 1985 versus 13% in 2000. Conclusion. Patients receiving standard care for RA in this setting had significantly better status, including radiographic scores, in 2000 than in 1985, associated with aggressive treatment strategies, prior to the introduction of biologic agents.
