We tracked mortality at 30 days, 1 year, and 5 years.

Key factors influencing mortality included age, comorbidities (e.g., heart failure, stroke, myocardial infarction, dementia), and care dependency levels. Women had lower risks than men across all periods. Short-term mortality was most affected by comorbidities, while long-term mortality correlated with chronic health conditions such as nicotine abuse and diabetes mellitus, and care needs. Surgery timing showed no consistent weekday effects.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Mortality differences reflect the impact of acute trauma from emergency surgery rather than the surgical procedure itself, emphasizing the need for optimized planning, preparation, early treatment and adaptable care structures in an aging population.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1007\/s00068-025-02882-y","type":"journal-article","created":{"date-parts":[[2025,5,20]],"date-time":"2025-05-20T08:10:48Z","timestamp":1747728648000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Comparing mortality in the elderly after proximal femur fractures and coxarthrosis: the effect of individual health characteristics and day of surgery"],"prefix":"10.1007","volume":"51","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2106-2940","authenticated-orcid":false,"given":"Anne","family":"Fink","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0584-343X","authenticated-orcid":false,"given":"Steffi S.I.","family":"Falk","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1627-2767","authenticated-orcid":false,"given":"Daniela","family":"Georges","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2025,5,20]]},"reference":[{"key":"2882_CR1","doi-asserted-by":"publisher","first-page":"41","DOI":"10.1007\/s00198-023-06907-3","volume":"35","author":"J-N Feng","year":"2024","unstructured":"Feng J-N, Zhang C-G, Li B-H, Zhan S-Y, Wang S-F, Song C-L.
