Univariable and multivariable linear regression was used to identify the association between socioeconomic factors and the WOOS index at 1 year following primary shoulder arthroplasty adjusted for age, sex, underlying diagnosis, implant design, and comorbidities. We examined socioeconomic factors including employment status, marital status, education, and income. Estimates were provided with 95% confidence intervals (CI).Results:\u00a02,292 patients were identified with a mean WOOS index of 76 (standard deviation 24). In the adjusted analysis, unemployed patients had a significantly lower WOOS index compared with patients with low-level jobs (14, CI 7.0\u201321), patients with high-level jobs (19, CI 12\u201325), and retired patients (14, CI 8.3\u201321). Low education level was associated with a lower WOOS index compared with medium education (4.8, CI 2.6\u20137.0) and high education level (7.7, CI 5.0\u201310). There was no association between WOOS index and income or marital status.Conclusion:\u00a0Unemployment and low education level were associated with worse WOOS index 1 year after shoulder arthroplasty for osteoarthritis or cuff-tear arthropathy. This highlights a potential inequity in patient-reported outcomes after shoulder arthroplasty.<\/jats:p>","DOI":"10.2340\/17453674.2024.42700","type":"journal-article","created":{"date-parts":[[2025,1,9]],"date-time":"2025-01-09T10:06:34Z","timestamp":1736417194000},"source":"Crossref","is-referenced-by-count":4,"title":["Association between socioeconomic status and patient-reported outcome at 1 year after shoulder arthroplasty for osteoarthritis or cuff-tear arthropathy: a nationwide cohort study of 2,292 arthroplasties"],"prefix":"10.2340","volume":"96","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4489-3771","authenticated-orcid":false,"given":"Marie L","family":"Jensen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Epaminondas M","family":"Valsamis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-8484-0860","authenticated-orcid":false,"given":"Alexander S","family":"Madrid","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3509-0742","authenticated-orcid":false,"given":"Bo S","family":"Olsen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeppe V","family":"Rasmussen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1183","published-online":{"date-parts":[[2025,1,9]]},"reference":[{"key":"93403","doi-asserted-by":"crossref","unstructured":"Rasmussen J V, Amundsen A, S\u00f8rensen A K B, Klausen T W, Jakobsen J, Jensen S L, et al.
