This study aims to use a comprehensive medical claims database in Japan to compare super-elderly patients aged 90\u00a0years and older with elderly aged 65\u201389 and clarify the risk of sequelae and in-hospital mortality in super-elderly patients.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Materials and methods<\/jats:title>\n            <jats:p>We retrospectively analyzed the Diagnosis Procedure Combination (DPC) database for all of Japan from April 2016 to March 2022. Medical records from approximately 1100 DPC-related hospitals were provided with consistent consent during this period. In this study, we focused on super-elderly patients and examined the association with the risk of postoperative pneumonia, pulmonary embolism, myocardial infarction, urinary tract infection, acute renal dysfunction, subsequent cognitive dysfunction, and in-hospital mortality after one-to-one propensity score matching.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>After performing propensity score matching based on sex and comorbidities, 129,953 pairs of patients were identified. These pairs were compared to elderly and super-elderly patients. The results of this study showed that compared with hip fractures in the elderly, hip fractures in the super-elderly were associated with an increased risk of pneumonia, urinary tract infection, acute renal dysfunction, subsequent cognitive dysfunction, and in-hospital mortality after adjustment for confounders. The odds ratio of in-hospital mortality was 2.190 (95% CI 2.062\u20132.325).<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion<\/jats:title>\n            <jats:p>As it has been shown that super-elderly patients with hip fractures are at greater risk of respiratory and urinary tract infections and increased in-hospital mortality, careful attention should be required for perioperative management.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1007\/s00774-024-01564-w","type":"journal-article","created":{"date-parts":[[2024,11,7]],"date-time":"2024-11-07T17:04:04Z","timestamp":1730999044000},"page":"141-148","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["Nationwide database study of postoperative sequelae and in-hospital mortality in super-elderly hip fracture patients"],"prefix":"10.1007","volume":"43","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8225-4690","authenticated-orcid":false,"given":"Yu","family":"Mori","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kunio","family":"Tarasawa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hidetatsu","family":"Tanaka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naoko","family":"Mori","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kiyohide","family":"Fushimi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toshimi","family":"Aizawa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenji","family":"Fujimori","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2024,11,7]]},"reference":[{"key":"1564_CR1","doi-asserted-by":"publisher","first-page":"364","DOI":"10.1046\/j.1532-5415.2003.51110.x","volume":"51","author":"RS Braithwaite","year":"2003","unstructured":"Braithwaite RS, Col NF, Wong JB (2003) Estimating hip fracture morbidity, mortality and costs.
