This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Introduction Coronavirus disease 2019 (COVID-19) has infected over 22 million individuals worldwide. It remains unclear whether patients with COVID-19 and Rheumatoid Arthritis (RA) experience worse clinical outcomes compared to similar patients with COVID-19 without RA. Objective The aim of this study is to provide insights on how COVID-19 impacted patients with RA given the nature of the disease and medication used. Methods RA cases were identified via International Classification of Diseases (ICD) codes and COVID-19 cases by laboratory results in the U.S. based TriNetX network. Patients with COVID-19 and RA were propensity-score matched based on demographics with patients with COVID-19 without RA at a 13 ratio. A hospitalized sub-population was defined by procedure codes. Results We identified 1,014 COVID-19 patients with RA and 3,042 non-RA matches selected from 137,757 patients. The odds of hospitalization (non-RA23%, RA24.6%, OR1.08, 95% CI 0.88 to 1.33) or mortality (non-RA5.4%, RA6%, OR0.93, 95% CI 0.65 to 1.34) were not significantly different. The hospitalized sub-population included 249 patients with COVID-19 and RA and 745 non-RA matches selected from 21,435 patients. The risk of intensive care unit (ICU) admission (non-RA18.8%, RA18.1%, OR0.94, 95% CI 0.60 to 1.45), and inpatient mortality (non-RA14.4%, RA14.5%, OR0.86, 95% CI 0.53 to 1.40) were not significantly different. Conclusion We did not find evidence suggesting patients with COVID-19 and RA are more likely to have severe outcomes than patients with COVID-19 without RA.
