There are only a few large-scale studies analyzing prehospital process databases of the fire department.<\/jats:p><\/jats:sec><jats:sec id=\"S1049023X23000353_as2\"><jats:title>Study Objective:<\/jats:title><jats:p>The aim of this study was to investigate whether characteristics of patients with FBAO were associated with prehospital factors and outcomes.<\/jats:p><\/jats:sec><jats:sec id=\"S1049023X23000353_as3\"><jats:title>Methods:<\/jats:title><jats:p>In this retrospective observational study, patients transferred to the hospital by the Tokyo, Japan Fire Department for FBAO from 2017 through 2019 were included. The association between neurologically favorable survival among the characteristics of patients with FBAO and prehospital factors affecting the outcomes was evaluated.<\/jats:p><\/jats:sec><jats:sec id=\"S1049023X23000353_as4\"><jats:title>Results:<\/jats:title><jats:p>Of the 2,429,175 patients, 3,807 (0.2%) patients had FBAO. The highest number of FBAO cases was 99 (2.6%), which occurred on January 1 (New Year\u2019s Day), followed by 40 cases (1.1%) on January 2, and 28 cases (0.7%) on January 3. The number of patients who experienced out-of-hospital cardiac arrest (OHCA) caused by FBAO was 1,644 (43.2%). Comparing the OHCA and non-OHCA groups, there were significant differences in age, sex, time spent at the site, and distance between the site and hospital. Cardiac arrest was significantly lower in infants after FBAO (P &lt; .001). In total, 98.2% of patients who did not have return of spontaneous circulation (ROSC) before hospital arrival died within 30 days, a significantly higher mortality rate than that in patients who had ROSC (98.2% versus 65.8%; P &lt; .001).<\/jats:p><\/jats:sec><jats:sec id=\"S1049023X23000353_as5\"><jats:title>Conclusions:<\/jats:title><jats:p>Among patients who did not have ROSC following FBAO upon arrival at the hospital, 98.2% died within 30 days. Thus, it is important to remove foreign bodies promptly and provide sufficient ventilation to the patient at the scene to increase the potential for ROSC. Further, more precautions should be exercised to prevent FBAO at the beginning of the year.<\/jats:p><\/jats:sec>","DOI":"10.1017\/s1049023x23000353","type":"journal-article","created":{"date-parts":[[2023,3,20]],"date-time":"2023-03-20T08:33:02Z","timestamp":1679301182000},"page":"326-331","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":4,"title":["Characteristics and Outcomes of Emergency Transferred Patients with Foreign Body Airway Obstruction in Tokyo, Japan"],"prefix":"10.1017","volume":"38","author":[{"given":"Ryotaro","family":"Suga","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4305-2850","authenticated-orcid":false,"given":"Yutaka","family":"Igarashi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tatsuya","family":"Norii","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takuya","family":"Kogure","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroki","family":"Kamimura","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yudai","family":"Yoshino","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kensuke","family":"Suzuki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shoji","family":"Yokobori","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Satoo","family":"Ogawa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroyuki","family":"Yokota","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2023,3,20]]},"reference":[{"key":"S1049023X23000353_ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.resuscitation.2020.03.013"},{"key":"S1049023X23000353_ref16","doi-asserted-by":"publisher","DOI":"10.1136\/bmjopen-2014-006462"},{"key":"S1049023X23000353_ref11","doi-asserted-by":"publisher","DOI":"10.2188\/jea.JE20160179"},{"key":"S1049023X23000353_ref4","doi-asserted-by":"publisher","DOI":"10.1161\/CIR.0000000000000892"},{"key":"S1049023X23000353_ref3","doi-asserted-by":"publisher","DOI":"10.1016\/j.resuscitation.2020.09.010"},{"key":"S1049023X23000353_ref12","doi-asserted-by":"publisher","DOI":"10.1136\/bmjresp-2017-000215"},{"key":"S1049023X23000353_ref6","unstructured":"6.
