Socioeconomic disparities in functional status in a national sample of patients with rheumatoid arthritis.
This longitudinal study looked at the association of socioeconomic disparities and functional status in a national sample of patients with rheumatoid arthritis (RA). This study used a cohort from the American College of Rheumatology’s Rheumatology Informatics System for Effectiveness (RISE) registry from 2016 to 2018. Analyses included all adult patients with a confirmed RA diagnosis and at least 1 functional status (FS) score documented. The Area Deprivation Index (ADI), a zip code-based indicator of poverty, was used as a proxy for socioeconomic status (SES). The cohort included 83,965 patients, of which 77% were women and 72% were non-Hispanic White. Mean age was 63.4 years. The probability of functional decline was 14.1% in the highest SES quintile and 18.9% in the lowest SES quintile. By all measures FS score was worse at lower SES levels.

Living in immigrant communities does not impact total knee arthroplasty outcomes: experience from a high-volume center in the United States.
The objective of this study was to assess the relationship of neighborhood immigrant proportion (IP) to preoperative and 2-year postoperative pain and function after elective total knee arthroplasty (TKA) using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Patients in a high-volume institutional TKA registry were analyzed retrospectively, and demographics, pre-op and 2-year post-op WOMAC pain and function scores, and addresses obtained. Patient-level variables were linked to Census Bureau tract data. Researchers conclude that patients living in high IP neighborhoods do not have worse pre-op or 2-year post-op pain and function outcomes after TKA compared to those living in lower IP neighborhoods.

Does education level mitigate the effect of poverty on total knee arthroplasty outcomes?
The authors assessed the interaction between education and poverty on 2-year Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain and function. They found that having no college was associated with worse pain and function at baseline and 2 years and that living in a poor neighborhood was associated with worse 2-year pain and function. There was a strong interaction between individual education and community poverty with WOMAC scores at 2 years. Patients without college living in poor communities had pain scores that were ~10 points worse than those with some college; in wealthy communities, college was associated with a 1-point difference in pain. Function was similar. The authors recommended further study on how education protects those in impoverished communities.
