TOPLINE:
A substantial proportion of older adults with early rheumatoid arthritis (RA) initiate glucocorticoids before receiving care from a rheumatologist. The early initiation of glucocorticoids in this group is associated with prolonged use.
METHODOLOGY:
- Researchers analyzed data from Medicare claims and Rheumatology Informatics System for Effectiveness registry of the American College of Rheumatology from 2016 to 2018 to assess the relationship between the timing of glucocorticoid initiation and the subsequent duration of glucocorticoid use in older adults with early RA in the United States.
- They included 1733 patients aged ≥ 65 years (mean age, 76 years; 67% women) with early RA.
- Glucocorticoid initiation was defined as the first use between 3 months before and 6 months after entrance into rheumatology care.
- The continuous administration of glucocorticoid therapy was monitored for all individuals who initiated glucocorticoid treatment for up to 12 months after entering rheumatology care.
- The primary outcome was the duration of continuous glucocorticoid use after entering rheumatology care.
TAKEAWAY:
- Glucocorticoids were initiated in 41% of patients, with 65% starting them before the initial RA diagnosis by a rheumatologist. The median duration of glucocorticoid use was 157 days.
- Patients with early RA who initiated glucocorticoids before entering rheumatology care showed a significantly longer duration of glucocorticoid use than those who initiated it later (median, 186 vs 97 days; P < .0001).
- Patients who initiated glucocorticoids before entering rheumatology care were 39% less likely to stop its use within 1 year (hazard ratio, 0.61; 95% CI, 0.51-0.74).
- The mean daily dose of glucocorticoids was < 5 mg/d for patients who received them for at least 3 months, indicating a trend toward low-dose, long-term use.
IN PRACTICE:
“Initiatives to reduce GC [glucocorticoid] exposure among patients with eRA [early RA] will likely require attention to rheumatology workforce shortages and close collaboration between rheumatologists and primary care clinicians to expedite referrals to rheumatology care,” the authors wrote.

This study was led by Andriko Palmowski, MD, Department of Rheumatology and Clinical Immunology, Charité – Universitätsmedizin Berlin in Germany, and was published online in Seminars in Arthritis and Rheumatism.
LIMITATIONS:
The observational nature of this study limited the ability to establish causality between early glucocorticoid initiation and the prolonged use of glucocorticoids. Moreover, the study population was limited to older adults, which affected the generalizability of the findings to younger populations. It also did not account for the fact that patients with more severe early RA were more likely to start glucocorticoid therapy early and continue it for longer durations.
DISCLOSURES:
The study was supported by research grants from the Deutsche Autoimmun-Stiftung and other sources. Some authors declared receiving grant support, consultancy fees, honoraria, and travel expenses and had other ties with various pharmaceutical companies.
