General anesthesia may suppress the airway\u2019s protective reflex. However, aspiration pneumonia is also observed in patients who undergo hip fracture surgery under spinal anesthesia. The aim of this study was to investigate the relationship between anesthesia methods and aspiration pneumonia as well as the predictive factors of aspiration pneumonia in elderly patients undergoing hip fracture surgery. Methods: The medical records of 19,809 patients aged \u226560\u00a0years who underwent hip fracture surgery under general or spinal anesthesia were reviewed. After propensity score matching, the anesthesia methods affecting the occurrences of aspiration pneumonia and other complications were investigated via logistic regression and instrumental variable analyses. Predictive factors of aspiration pneumonia were also investigated in all subjects using a multivariable logistic regression analysis. Results: Among the 11,673 general anesthesia patients and 8136 spinal anesthesia patients, aspiration pneumonia occurred in 356 patients (1.8%). Post-propensity score matching the incidences of aspiration pneumonia with general and spinal anesthesia were 1.8% and 1.5%, respectively ( p = 0.158); other pulmonary complications were 1.5% and 1.5%, respectively ( p = 0.893); and the mortality rates were 1.4% and 1.2%, respectively ( p = 0.219). The predictive factors of aspiration pneumonia were advanced age, male sex, lean body, cerebrovascular disease, dementia, and dependency for activities of daily living (eating). Conclusion: Spinal and general anesthesia showed similar incidences of aspiration pneumonia in elderly hip fracture surgery. Regardless of the anesthesia method, great care should be taken, especially in elderly patients with the identified predictive factors.<\/jats:p>","DOI":"10.1177\/10225536221078622","type":"journal-article","created":{"date-parts":[[2022,2,28]],"date-time":"2022-02-28T12:27:56Z","timestamp":1646051276000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":8,"title":["Aspiration pneumonia and anesthesia techniques in hip fracture surgery in elderly patients: A retrospective cohort study using administrative data"],"prefix":"10.1177","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4230-7038","authenticated-orcid":false,"given":"Taeko","family":"Fukuda","sequence":"first","affiliation":[{"name":"Department of Anesthesiology, Faculty of Medicine, University of Tsukuba, Tsukuba, Japan"},{"name":"Kasumigaura Medical Center Hospital (Tsuchiura Clinical Education and Training Center), National Hospital Organization, Tsuchiura, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shinobu","family":"Imai","sequence":"additional","affiliation":[{"name":"Department of Clinical Data Management and Research, National Hospital Organization Headquarters, Tokyo, Japan"},{"name":"Department of Drug Safety and Risk Management, School of Pharmacy, Tokyo University of Pharmacy and Life Sciences, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shunji","family":"Shimoda","sequence":"additional","affiliation":[{"name":"Department of Clinical Data Management and Research, National Hospital Organization Headquarters, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazushi","family":"Maruo","sequence":"additional","affiliation":[{"name":"Department of Biostatistics, Faculty of Medicine, University of Tsukuba, Tsukuba, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masaya","family":"Nakadera","sequence":"additional","affiliation":[{"name":"Department of Clinical Data Management and Research, National Hospital Organization Headquarters, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiromasa","family":"Horiguchi","sequence":"additional","affiliation":[{"name":"Department of Clinical Data Management and Research, National Hospital Organization Headquarters, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2022,2,28]]},"reference":[{"key":"bibr1-10225536221078622","doi-asserted-by":"publisher","DOI":"10.1097\/01.CCM.0000069738.73602.5F"},{"key":"bibr2-10225536221078622","doi-asserted-by":"publisher","DOI":"10.1097\/BRS.0b013e31829cc19b"},{"key":"bibr3-10225536221078622","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijsu.2016.01.043"},{"key":"bibr4-10225536221078622","doi-asserted-by":"publisher","DOI":"10.1111\/j.1532-5415.2008.01597.x"},{"key":"bibr5-10225536221078622","doi-asserted-by":"publisher","DOI":"10.1007\/s00198-006-0172-4"},{"key":"bibr6-10225536221078622","doi-asserted-by":"publisher","DOI":"10.1007\/PL00004148"},{"key":"bibr7-10225536221078622","doi-asserted-by":"publisher","DOI":"10.1002\/lary.26744"},{"key":"bibr8-10225536221078622","doi-asserted-by":"publisher","DOI":"10.1097\/00000542-200501000-00007"},{"key":"bibr9-10225536221078622","doi-asserted-by":"publisher","DOI":"10.1093\/bja\/70.5.574"},{"key":"bibr10-10225536221078622","doi-asserted-by":"publisher","DOI":"10.1002\/lary.24539"},{"key":"bibr11-10225536221078622","doi-asserted-by":"publisher","DOI":"10.2165\/00003088-199936010-00002"},{"key":"bibr12-10225536221078622","doi-asserted-by":"publisher","DOI":"10.1097\/00000542-199103000-00017"},{"key":"bibr13-10225536221078622","doi-asserted-by":"publisher","DOI":"10.1097\/00000542-199311000-00005"},{"key":"bibr14-10225536221078622","volume-title":"Global Database on Body Mass Index","author":"World Health Organization"},{"key":"bibr15-10225536221078622","doi-asserted-by":"publisher","DOI":"10.3109\/09638288809164103"},{"key":"bibr16-10225536221078622","doi-asserted-by":"publisher","DOI":"10.1177\/2309499017754106"},{"key":"bibr17-10225536221078622","doi-asserted-by":"publisher","DOI":"10.1097\/01.mlr.0000182534.19832.83"},{"key":"bibr18-10225536221078622","doi-asserted-by":"publisher","DOI":"10.1016\/0895-4356(94)90129-5"},{"key":"bibr19-10225536221078622","doi-asserted-by":"publisher","DOI":"10.1515\/em-2018-0024"},{"key":"bibr20-10225536221078622","doi-asserted-by":"crossref","first-page":"119","DOI":"10.1111\/ggi.13559","volume":"19","author":"Byun SE","year":"2019","journal-title":"Geriatr Gerontology International"},{"key":"bibr21-10225536221078622","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000019108"},{"key":"bibr22-10225536221078622","doi-asserted-by":"publisher","DOI":"10.1016\/j.injury.2015.02.002"},{"key":"bibr23-10225536221078622","unstructured":"Sjolander A, Dahlqwist E, Martinussen T.
