Rheumatoid Arthritis, Frailty, and Outcomes of Surgical Hospitalizations: A National Population‐Based Analysis

open access: yesArthritis Care &Research, EarlyView.
Objective Hospitalization, particularly for surgery, represents a period of heightened stress. We evaluated how frailty attenuates the association of rheumatoid arthritis (RA) with negative health outcomes after elective noncardiac surgery. Methods We conducted a cross‐sectional study using the National Inpatient Sample (2018 to 2020), including adults
