Several clinical conditions may affect outcome, including baseline characteristics, co-existing acute illnesses, perioperative factors, and postoperative complications. Our primary objective was to estimate the respective effect of these four domains on six-month mortality after HF. A retrospective observational study using a monocentric cohort of older patients was conducted. All patients \u2265 70 years old admitted to the emergency department for HF and hospitalized in our perioperative geriatric care unit from June 2009 to September 2018 were included. Among 1015 included patients, five (0.5%) were lost to follow-up, and 1010 were retained in the final analysis (mean age 86 \u00b1 6 years). The six-month mortality rate was 14.8%. The six-month attributable mortality estimates were as follows: baseline characteristics (including age, gender, comorbidities, autonomy, type of fracture): 62.4%; co-existing acute illnesses (including acute events present before surgery that could result from the fracture or cause it): 0% (not significantly associated with six-month mortality); perioperative factors (including blood transfusion and delayed surgery): 12.3%; severe postoperative complications: 11.9%. Baseline characteristics explained less than two-thirds of the six-month mortality after HF. Optimizing patients care by improving management of perioperative factors and thus decreasing postoperative complications, could reduce by a maximum of one quarter of the six-month mortality rate after HF.<\/jats:p>","DOI":"10.3390\/jcm9082370","type":"journal-article","created":{"date-parts":[[2020,7,24]],"date-time":"2020-07-24T09:06:09Z","timestamp":1595581569000},"page":"2370","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Attributable Mortality of Hip Fracture in Older Patients: A Retrospective Observational Study"],"prefix":"10.3390","volume":"9","author":[{"given":"Lor\u00e8ne","family":"Zerah","sequence":"first","affiliation":[{"name":"Department of Geriatric Medicine, H\u00f4pital la Piti\u00e9-Salp\u00eatri\u00e8re, Assistance Publique-H\u00f4pitaux de Paris (APHP), 75013 Paris, France"},{"name":"UMRS INSERM 1136, Institut Pierre Louis d\u2019Epid\u00e9miologie et de Sant\u00e9 Publique, Sorbonne Universit\u00e9, 75013 Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Hajage","sequence":"additional","affiliation":[{"name":"UMRS INSERM 1136, Institut Pierre Louis d\u2019Epid\u00e9miologie et de Sant\u00e9 Publique, Sorbonne Universit\u00e9, 75013 Paris, France"},{"name":"Department of Biostatistics, H\u00f4pital la Piti\u00e9-Salp\u00eatri\u00e8re, APHP, 75013 Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mathieu","family":"Raux","sequence":"additional","affiliation":[{"name":"UMRS INSERM 1158, Sorbonne Universit\u00e9, 75013 Paris, France"},{"name":"Department of Anesthesiology and Critical Care, H\u00f4pital la Piti\u00e9-Salp\u00eatri\u00e8re, APHP, 75013 Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Judith","family":"Cohen-Bittan","sequence":"additional","affiliation":[{"name":"Department of Geriatric Medicine, H\u00f4pital la Piti\u00e9-Salp\u00eatri\u00e8re, Assistance Publique-H\u00f4pitaux de Paris (APHP), 75013 Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anthony","family":"M\u00e9zi\u00e8re","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation, H\u00f4pital Charles Foix, APHP, 94200 Ivry sur Seine, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fr\u00e9d\u00e9ric","family":"Khiami","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery and Trauma, H\u00f4pital La Piti\u00e9-Salp\u00eatri\u00e8re, APHP, 75013 Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yannick Le","family":"Manach","sequence":"additional","affiliation":[{"name":"Departments of Anesthesia &amp; Health Research Methods, Evidence &amp; Impact (HEI), Michael DeGroote School of Medicine, Faculty of Health Sciences, McMaster University, Hamilton, ON L8S 4L8, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1205-4738","authenticated-orcid":false,"given":"Bruno","family":"Riou","sequence":"additional","affiliation":[{"name":"UMRS INSERM 1166, IHU ICAN, Sorbonne Universit\u00e9, 75013 Paris, France"},{"name":"Department of Emergency Medicine and Surgery, H\u00f4pital La Piti\u00e9-Salp\u00eatri\u00e8re, APHP, 75013 Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jacques","family":"Boddaert","sequence":"additional","affiliation":[{"name":"Department of Geriatric Medicine, H\u00f4pital la Piti\u00e9-Salp\u00eatri\u00e8re, Assistance Publique-H\u00f4pitaux de Paris (APHP), 75013 Paris, France"},{"name":"UMR INSERM U1135, Sorbonne Universit\u00e9, 75013 Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,7,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2231","DOI":"10.1001\/jama.2019.5453","article-title":"Hip fractures in older adults in 2019","volume":"321","author":"Berry","year":"2019","journal-title":"JAMA"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1573","DOI":"10.1001\/jama.2009.1462","article-title":"Incidence and mortality of hip fractures in the United States","volume":"302","author":"Brauer","year":"2009","journal-title":"JAMA"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"1726","DOI":"10.1007\/s00198-006-0172-4","article-title":"An estimate of the worldwide prevalence and disability associated with osteoporotic fractures","volume":"17","author":"Johnell","year":"2006","journal-title":"Osteoporos.
