Previous studies document risk factors for post-operative delirium but have frequently excluded patients with pre-operative delirium. &lt;b&gt;&lt;i&gt;Objective:&lt;\/i&gt;&lt;\/b&gt; This study endeavours to document prevalence and risk factors for pre-operative delirium in hip fracture patients and compares risk factor profiles and outcomes between pre- and post-operative delirium. &lt;b&gt;&lt;i&gt;Methods:&lt;\/i&gt;&lt;\/b&gt; 283 hip fracture patients were assessed pre-operatively with the Delirium Elderly At Risk (DEAR) instrument, Mini-Mental State Examination (MMSE), and Confusion Assessment Method (CAM). They were followed on post-operative days 1, 3, and 5 for the presence of delirium. Doses of opioids were recorded. Wait time to surgery, length of stay, and discharge site were noted. &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; Delirium was present in 57.6% patients pre-operatively and 41.7% post-surgery. Not all patients (62%) with pre-operative delirium also had post-operative delirium. There was a considerable overlap in risk factors, with some differences. Wait time to surgery, number of comorbidities, and total pre-operative opioid and lorazepam doses were associated with pre- but not post-operative delirium. Negative outcomes were more closely associated with post-operative delirium. &lt;b&gt;&lt;i&gt;Conclusion:&lt;\/i&gt;&lt;\/b&gt; Delirium is common in pre-hip fracture surgery patients, and not all patients with pre-operative delirium go on to have post-operative delirium. Risk factor profiles are not identical, raising the possibility of identifying and intervening in patients at high risk of delirium pre-operatively.<\/jats:p>","DOI":"10.1159\/000442385","type":"journal-article","created":{"date-parts":[[2015,12,14]],"date-time":"2015-12-14T17:01:20Z","timestamp":1450112480000},"page":"396-400","source":"Crossref","is-referenced-by-count":30,"title":["Prevalence and Characteristics of Pre-Operative Delirium in Hip Fracture Patients"],"prefix":"10.1159","volume":"62","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0157-7007","authenticated-orcid":false,"given":"Susan","family":"Freter","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Dunbar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katalin","family":"Koller","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chris","family":"MacKnight","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenneth","family":"Rockwood","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2015,12,15]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ocl.2013.01.003"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1017\/S104161020600425X"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1111\/j.1532-5415.2009.02377.x"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/S0167-4943(02)00058-4"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1046\/j.1532-5415.2001.49261.x"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199903043400901"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1016\/0022-3956(75)90026-6"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1093\/ageing\/afh245"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1093\/ageing\/afi099"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.5770\/cgj.18.185"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-113-12-941"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1080\/01621459.1961.10482090"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1016\/j.archger.2012.03.001"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1093\/ageing\/afs021"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2318-8-24"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1093\/gerona\/62.7.738"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1016\/j.jagp.2013.01.069"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1111\/j.1471-6712.1997.tb00450.x"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1111\/j.1399-6576.2010.02232.x"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.3233\/JAD-2010-101299"}],"container-title":["Gerontology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/442385","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/442385","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/442385","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T14:08:45Z","timestamp":1745417325000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000442385"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,12,15]]},"references-count":20,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2016,6,16]]}},"URL":"https:\/\/doi.org\/10.1159\/000442385","archive":["Portico"],"relation":{},"ISSN":["0304-324X","1423-0003"],"issn-type":[{"value":"0304-324X","type":"print"},{"value":"1423-0003","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,12,15]]}}}
