ObjectiveTo identify longitudinal predictors of discordance between patients with rheumatoid arthritis (RA) and their health care providers, where patient global assessment of disease activity is substantially higher than provider global assessment.MethodsThis retrospective case–control study included 102 cases with positive discordance (i.e., ≥25 mm between patient and provider global assessments) and 102 controls without discordance who were matched for age, sex, RA duration, and Clinical Disease Activity Index (CDAI) score. Data were collected at the baseline visit (date of diagnosis or earliest available visit), the index visit (participation in a previous cross‐sectional study), and at up to 11 additional visits before the index visit. Data included patient characteristics, disease activity measures, Disease Activity Score in 28 joints (3‐variable) using the C‐reactive protein level (DAS28‐CRP), and medications. Data were analyzed by using linear and logistic regression models with smoothing splines for nonlinear trends.ResultsOverall, the mean age was 63 years, 75% of patients were female, and the mean RA duration was 10 years. Compared with controls, cases had higher rates of discordant visits during the 4 years before the index visit, and they had a higher CDAI score and DAS28‐CRP earlier in the disease course. Cases more frequently had antinuclear antibodies, nonerosive disease, prior depression, or prior use of antidepressants or fibromyalgia medications. Disease‐modifying medication use was not different between cases and controls.ConclusionThe findings inform new hypotheses about the relationships of disease activity and antinuclear antibodies to the later occurrence of positive discordance among patients with RA.

ObjectiveDue to an aging population, increasing prevalence of rheumatic disease, and a growing supply and demand gap of rheumatology providers, innovative solutions are needed to meet the needs of persons with rheumatic conditions. Nurse practitioners (NPs) and physician assistants (PAs) have been identified as a group of health professionals who could help address the workforce shortage. The Executive Committee of the Association of Rheumatology Health Professionals (ARHP), a division of the American College of Rheumatology (ACR), charged a task force to facilitate the preparation of NPs/PAs to work in a rheumatology practice setting.MethodsThe task force, consisting of private practice and academic rheumatologists, and NPs and PAs, from both adult and pediatric settings, conducted a needs assessment survey of current NPs and PAs to identify mechanisms for acquiring rheumatology knowledge. Through face‐to‐face and webinar meetings, and incorporating stakeholder feedback, the task force designed a rheumatology curriculum outline to enrich the training of new NPs and PAs joining rheumatology practice.ResultsInformed by the needs assessment data and stakeholders, an NP/PA rheumatology curriculum outline was developed and endorsed by the ACR Board of Directors for use by community‐based and academic rheumatology practices, whether pediatric or adult, who desire to add NPs and PAs to their practice setting.ConclusionAs rheumatology is facing workforce shortages, the ACR/ARHP rheumatology curriculum outline can be utilized to train NPs and PAs and create more efficient integration of NPs and PAs into rheumatology practice.
