This study aimed to determine the factors associated with choking among acute hospital patients and examine error-producing conditions to suggest choking-prevention policies. Among 36,364 cases reported by hospital staff at an acute university hospital from 2012 to 2018 were examined using a retrospective study, 35,440 were analysis as the number of cases analysed for the study. We used descriptive statistics to present patient characteristics and conducted univariable and multivariable logistic regression analyses to identify factors associated with choking. Additionally, we conducted content analysis (root cause analysis) to examine error-producing conditions and prevention policies. Sixty-eight cases were related to choking injuries; of these, 43 patients (63.2%) were male, and 38 (55.9%) were aged 65 years and older. Choking cases had a high percent of adverse outcomes involving residual impairment or death (n = 23, 33.8%). Mental illness (adjusted odds ratio [95% confidence interval]: 3.14 [1.39\u22127.08]), and hospitalisation in the general wards (adjusted odds ratio [95% confidence interval]: 3.13 [1.70\u22125.76]) were associated with an increased probability of choking. Error production was caused by food (n = 25, 36.8%) and medical devices or supplies (n = 13, 19.1%). Almost all contributory factors were associated with inadequate checking (n = 66, 97.1%) and misperception of risk (n = 65, 95.6%). Choking poses a highly significant burden on patients, and hospital administrators should minimise the risk of choking to prevent related injuries. Hospital administrators should provide training and education to their staff and develop adequate protocols and procedures to prevent choking.<\/jats:p>","DOI":"10.1371\/journal.pone.0267430","type":"journal-article","created":{"date-parts":[[2022,4,27]],"date-time":"2022-04-27T17:29:43Z","timestamp":1651080583000},"page":"e0267430","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":6,"title":["Choking injuries: Associated factors and error-producing conditions among acute hospital patients in Japan"],"prefix":"10.1371","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6365-9310","authenticated-orcid":true,"given":"Naomi","family":"Akiyama","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9546-9869","authenticated-orcid":true,"given":"Ryuji","family":"Uozumi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomoya","family":"Akiyama","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Keisuke","family":"Koeda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takeru","family":"Shiroiwa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kuniaki","family":"Ogasawara","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"340","published-online":{"date-parts":[[2022,4,27]]},"reference":[{"issue":"3","key":"pone.0267430.ref001","doi-asserted-by":"crossref","first-page":"122","DOI":"10.1097\/PTS.0b013e3182948a69","article-title":"A new, evidence-based estimate of patient harms associated with hospital care","volume":"9","author":"JT James","year":"2013","journal-title":"J Patient Saf"},{"issue":"39","key":"pone.0267430.ref002","doi-asserted-by":"crossref","first-page":"e8128","DOI":"10.1097\/MD.0000000000008128","article-title":"Estimation of the number of patient deaths recognized by a medical practitioner as caused by adverse events in hospitals in Japan: A cross-sectional study","volume":"96","author":"S Fujita","year":"2017","journal-title":"Medicine (Baltimore)"},{"key":"pone.0267430.ref003","first-page":"1","article-title":"Deaths from unintentional injury among adults aged 65 and over: United States, 2000\u20132013","volume":"199","author":"E Kramarow","year":"2015","journal-title":"NCHS Data Brief"},{"key":"pone.0267430.ref004","unstructured":"Food Safety Commission of Japan.
