ObjectivePatients with rheumatoid arthritis (RA) frequently visit emergency departments (EDs), but their clinical characteristics and admission factors are poorly understood. Our study investigates the epidemiology and outcomes of ED visits among patients with RA using the Nationwide Emergency Department Sample (NEDS).MethodsThis cross‐sectional study used the 2019 NEDS data to identify RA‐related ED visits using International Classification of Disease, Tenth Revision codes M05.X or M06.X. RA‐related ED visits were defined as encounters in which RA was recorded in any diagnostic position. Demographics, clinical features, and comorbidities were compared between RA and non‐RA ED visits. Racial variations were assessed, and multivariable logistic regression identified factors associated with inpatient admission.ResultsWe identified 905,811 (0.8%) ED visits for adults aged ≥18 years with RA. Compared to non‐RA visits, RA ED visits had a higher proportion of patients aged ≥65 years, women, White patients, and Medicare‐insured individuals with a greater comorbidity burden. Admission rates were 46% for RA visits versus 16% for non‐RA visits. Black and Hispanic patients with RA were younger than White patients and more likely to belong to the lowest income quartile. Older age, male sex, and comorbidities were associated with higher admission odds, whereas Black race, lowest income quartile, and Medicaid coverage correlated with lower odds of admission. Septicemia was the most common primary ED diagnosis in patients with RA.ConclusionPatients with RA visiting the ED were older, had a higher comorbidity burden, and were three times more likely to be admitted than patients without RA. Black patients and those in the lowest income quartile had lower odds of admission, highlighting potential disparities and the need for targeted interventions to improve health equity.

Objective We investigated prolonged COVID-19 symptom duration, defined as lasting 28 days or longer, among people with systemic autoimmune rheumatic diseases (SARDs). Methods We analysed data from the COVID-19 Global Rheumatology Alliance Vaccine Survey (2 April 2021–15 October 2021) to identify people with SARDs reporting test-confirmed COVID-19. Participants reported COVID-19 severity and symptom duration, sociodemographics and clinical characteristics. We reported the proportion experiencing prolonged symptom duration and investigated associations with baseline characteristics using logistic regression. Results We identified 441 respondents with SARDs and COVID-19 (mean age 48.2 years, 83.7% female, 39.5% rheumatoid arthritis). The median COVID-19 symptom duration was 15 days (IQR 7, 25). Overall, 107 (24.2%) respondents had prolonged symptom duration (≥28 days); 42/429 (9.8%) reported symptoms lasting ≥90 days. Factors associated with higher odds of prolonged symptom duration included: hospitalisation for COVID-19 vs not hospitalised and mild acute symptoms (age-adjusted OR (aOR) 6.49, 95% CI 3.03 to 14.1), comorbidity count (aOR 1.11 per comorbidity, 95% CI 1.02 to 1.21) and osteoarthritis (aOR 2.11, 95% CI 1.01 to 4.27). COVID-19 onset in 2021 vs June 2020 or earlier was associated with lower odds of prolonged symptom duration (aOR 0.42, 95% CI 0.21 to 0.81). Conclusion Most people with SARDs had complete symptom resolution by day 15 after COVID-19 onset. However, about 1 in 4 experienced COVID-19 symptom duration 28 days or longer; 1 in 10 experienced symptoms 90 days or longer. Future studies are needed to investigate the possible relationships between immunomodulating medications, SARD type/flare, vaccine doses and novel viral variants with prolonged COVID-19 symptoms and other postacute sequelae of COVID-19 among people with SARDs.
