This study explores concerns and behaviors of patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), and systemic lupus erythematosus (SLE) during the early months of the COVID-19 pandemic. Through a survey conducted within the ArthritisPower registry, it was found that patients with autoimmune rheumatic disease frequently avoided office visits, laboratory testing and experienced DMARD interruptions that were not recommended by a physician. Concerns and behaviors were compared among patients with different conditions, disease-modifying antirheumatic drug (DMARD) use, geographic measures of urban status, income, education, and COVID-19 activity.
