However, the relationship between blood transfusion and POD has been heatedly debated. The purpose of this study was to evaluate the risk factors of POD and the relationship between blood transfusions and the occurrence of POD in hip fracture surgery through big data analysis. Methods: Medical data (including medication history, clinical and laboratory findings, and perioperative variables) were acquired from the clinical data warehouse (CDW) of the five hospitals of Hallym University Medical Center and were compared between patients without POD and with POD. Results: The occurrence of POD was 18.7% (228 of 2398 patients). The risk factors of POD included old age (OR 4.38, 95% CI 2.77\u20136.91; p &lt; 0.001), American Society of Anesthesiology physical status &gt; 2 (OR 1.84 95% CI 1.4\u20132.42; p &lt; 0.001), dementia (OR 1.99, 95% CI 1.53\u20132.6; p &lt; 0.001), steroid (OR 0.53 95% CI 0.34\u20130.82; p &lt; 0.001), Antihistamine (OR 1.53 95% CI 1.19\u20131.96; p &lt; 0.001), and postoperative erythrocyte sedimentation rate (mm\/h) (OR 0.97 95% CI 0.97\u20130.98; p &lt; 0.001) in multivariate logistic regression analysis. The postoperative transfusion (OR 2.53, 95% CI 1.88\u20133.41; p &lt; 0.001) had a significant effect on the incidence of POD. Conclusions: big data analytics using a CDW was a good option to identify the risk factors of POD and to prevent POD in hip fracture surgery.<\/jats:p>","DOI":"10.3390\/jcm12144696","type":"journal-article","created":{"date-parts":[[2023,7,17]],"date-time":"2023-07-17T00:56:47Z","timestamp":1689555407000},"page":"4696","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["The Impact of Blood Transfusion in Developing Postoperative Delirium in Patients with Hip Fracture Surgery"],"prefix":"10.3390","volume":"12","author":[{"given":"Sang-Soo","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery, Chuncheon Sacred Heart Hospital, Hallym University College of Medicine, Chuncheon 24253, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3818-2239","authenticated-orcid":false,"given":"Jong-Ho","family":"Kim","sequence":"additional","affiliation":[{"name":"Division of Big Data and Artificial Intelligence, Institute of New Frontier Research, Chuncheon Sacred Heart Hospital, Hallym University College of Medicine, Chuncheon 24253, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jae-Jun","family":"Lee","sequence":"additional","affiliation":[{"name":"Division of Big Data and Artificial Intelligence, Institute of New Frontier Research, Chuncheon Sacred Heart Hospital, Hallym University College of Medicine, Chuncheon 24253, Republic of Korea"},{"name":"Department of Anesthesiology and Pain Medicine, College of Medicine, Chuncheon Sacred Heart Hospital, Hallym University College of Medicine, Chuncheon 24253, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7753-8464","authenticated-orcid":false,"given":"Young-Suk","family":"Kwon","sequence":"additional","affiliation":[{"name":"Division of Big Data and Artificial Intelligence, Institute of New Frontier Research, Chuncheon Sacred Heart Hospital, Hallym University College of Medicine, Chuncheon 24253, Republic of Korea"},{"name":"Department of Anesthesiology and Pain Medicine, College of Medicine, Chuncheon Sacred Heart Hospital, Hallym University College of Medicine, Chuncheon 24253, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7964-9694","authenticated-orcid":false,"given":"Eun-Min","family":"Seo","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Chuncheon Sacred Heart Hospital, Hallym University College of Medicine, Chuncheon 24253, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,14]]},"reference":[{"key":"ref_1","first-page":"15","article-title":"Clinical profile and association of delirium in geriatric patients with hip fractures in a tertiary care hospital in India","volume":"58","author":"Chrispal","year":"2010","journal-title":"J.
