listed in. Only 9% were not on DMARD therapy. Thirty-four percent of individuals were using a biologic or targeted synthetic DMARD (n 5 20,759), while 67% were using a nonbiologic DMARD (n 5 40,272). Twenty-three percent were on biologic DMARD monotherapy. As expected, methotrexate was the most commonly used DMARD (43.5%), followed by hydroxychloroquine (23.3%). Performance on selected RISE quality measures is listed in Table 4. For example, performance on assessment of disease activity (NQF 2523) was 55.2%. Among those satisfying this measure, the most commonly used outcome measures were Routine Assessment of Patient Index Data 3 (RAPID-3; 56.0%) and Clinical Disease Activity Index (36.9%), with fewer patients having Simplified Disease Activity Index (0.04%), Disease Activity Score in 28 joints (3.8%), or Patient Activity Scale II (3.2%) scores recorded in the EHR. For functional status assessment (NQF 2524), performance was 53.6% and a majority of practices used the RAPID-3/modified Health Assessment Questionnaire (HAQ; 45.2% of scores reported in the EHR) or a version of the HAQ (original HAQ 38.5% or HAQ-II 3.3%). As is reflected in the medication data, 91.0% of patients met the criteria for DMARD therapy (NQF 2525). For tuberculosis Table 2.

Across all measures in Table 4, performance was highest for a measure regarding medication reconciliation (96.8%) and lowest for serum urate monitoring in gout patients (31.0%). Some information was missing for all variables, but the proportion of missing data was low for most sociodemographic data, except for insurance status (19.3%). Work is ongoing to understand the accuracy of diagnosis codes and medications in RISE, with initial data suggesting very good specificity for RA and for DMARDs (2). The extent of missingness as well as accuracy is expected to improve as mapping and validation procedures for RISE continue in the coming years. DISCUSSION Payment reform, a proliferation of new medication options, and the widespread introduction of EHRs are transforming the practice of rheumatology in the US. Given these changes, the ACR launched the RISE registry to help rheumatologists succeed in advancing the triple aim of improving the care experience, improving the health of populations, and reducing the costs of care (3).
