2523), functional status assessment (NQF 2524), tuberculosis screening (NQF 2522), and DMARD therapy (NQF 2525), as well as additional measures in the areas of drug safety (use of highrisk medications in the elderly), osteoporosis (screening and treatment), preventive health (tobacco use, obesity, and blood pressure management), gout (monitoring and serum urate), and medication reconciliation. We assessed the number of times the recommended process of care was performed among the eligible denominator population to arrive at the average performance on each measure. A higher average denotes higher quality with the exception of the measures regarding high-risk prescribing in the elderly, in which a lower average denotes higher quality. A complete list of the 2015 RISE measures is included in Supplementary Appendix A (available on the Arthritis Care & Research web site at http://onlinelibrary.wiley.com/doi/10.1002/acr. 23089/abstract). The measures are evaluated and updated annually. RESULTS As of September 30, 2015, there were 312 clinicians and 55 practices participating in RISE. Seventy-two percent of clinicians were in a group practice, 21% were solo practitioners, and 7% were part of a larger health system. Sociodemographic and clinical characteristics of the 239,302 patients are in Table 1. A majority of patients were women (74.8%), 22.2% were racial/ethnic.

Using RISE Registry to Improve Quality of Care 1869 minorities, and most had commercial insurance (47.8%). Almost one-third (29.6%) had Medicare health insurance. At their last clinical encounter, 10.4% of patients were smokers, and 14.6% were hypertensive (systolic blood pressure of .140 mm Hg or a diastolic blood pressure of .90 mm Hg). In Table 2, we list the diagnoses captured in RISE, as defined by ICD-9 codes at the last clinical encounter. Among the diagnoses examined, osteoarthritis was the most prevalent (n 5 76,381), followed by RA (n 5 60,102). RISE also includes a significant number of individuals with other rheumatologic disorders, such as Sjogren’s syndrome (n € 5 15,800), systemic lupus erythematosus (n5 13,940), dermatomyositis (n 5 1,129), and temporal arteritis (n 5 1,596). Less common conditions, such as relapsing polychondritis (n 5 886), Behc¸et’s syndrome (n 5 301), and Takayasu disease (n 5 85), are also represented. For the subset of individuals with ICD-9 codes for RA (n5 60,102), active medications at the last clinical encounter are
