Brief report: rheumatoid arthritis response criteria and patient-reported improvement in arthritis activity: is an American College of Rheumatology twenty percent response meaningful to patients?

ABSTRACT:

Objective

To examine the association of the American College of Rheumatology (ACR) response criteria (20% improvement [ACR20], ACR50, and ACR70) and the European League Against Rheumatism (EULAR) response criteria with patient-reported improvement in rheumatoid arthritis (RA) activity.

Methods

Two hundred fifty patients with active RA were studied prospectively, before and after escalation of antirheumatic treatment. Patients were asked to report if they subjectively judged that they had experienced important improvement with treatment, and the proportion of patients who reported improvement was compared with the proportion who met the ACR20, ACR50, ACR70, and EULAR response criteria.

Results

Improvement in overall arthritis status was reported by 167 patients (66.8%)
