Medication cost concerns were defined as having difficulties affording SLE medications, skipping doses, delaying refills, requesting lower-cost alternatives, purchasing medications outside the United States, or applying for patient assistance programs. Linear regression and mixed effects models assessed the cross-sectional and longitudinal association of medication cost concerns and PROs, respectively, adjusting for age, sex, race and ethnicity, income, principal insurance, immunomodulatory medications, and organ damage.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of 334 participants, medication cost concerns were reported by 91 (27%).
