Routine Use of Quantitative Disease Activity Measurements among US Rheumatologists: Implications for Treat-to-target Management Strategies in Rheumatoid Arthritis.

Objective: The aim of our study was to examine why real-world practices and attitudes regarding quantitative measurements of rheumatoid arthritis (RA) have received limited attention.

Methods: An e-mail survey asked US rheumatologists to self-report on their use of quantitative measurements (metric).

Results: Among 439 respondents, metric rheumatologists (58%) were more likely to be in group practice and to use tumor necrosis factor inhibitors.
