Abstract
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. The quantitative tools most commonly used were the Health Assessment Questionnaire (35.5%) and the Routine Assessment of Patient Index Data 3 (27.1%). Reasons for not measuring included time needed and electronic availability. Based on simulated case scenarios, providing more quantitative information increased the likelihood that a patient would change to a different disease-modifying antirheumatic drug or biologic. CONCLUSION: Routine use of quantitative measurement for patients in the United States with RA is increasing over time but remains low.
