The proportion of 1-month survival was 6.2% (510\/8239) in external causes, 6.5% (94\/1148) in respiratory diseases, 0.8% (11\/1309) in malignant tumours, 4.9% (55\/1114) in strokes and 4.1% (85\/2054) in others. As for external causes, the proportion of 1-month survival was 14.3% (382\/2670) in asphyxia, 4.2% (84\/1999) in hanging, 0.7% (9\/1300) in fall, 1.1% (12\/1062) in drowning, 1.6% (12\/765) in traffic injury, 3.7% (7\/187) in drug overuse and 1.6% (4\/256) in unclassified external causes. In a multivariate analysis, adults aged &lt;65\u2005years old with arrests witnessed by bystanders, with normal activities of daily living before the arrests, having ventricular fibrillation arrests, having arrests in public places, intravenous fluid levels and early Emergency Medical Service response time were significant predictors for 1-month outcome after OHCAs of non-cardiac origin. The proportion of 1-month survival of all OHCAs of non-cardiac origin did not significantly increase (from 4.3% (86\/2023) in 2005 to 4.9% (105\/2126) in 2011) and the adjusted OR for one-increment of year was 1.01 (95% CI 0.97 to 1.06).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>From a large OHCA registry in Osaka, we demonstrated that 1-month survival after OHCAs of non-cardiac origin was poor and stable.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1136\/bmjopen-2014-006462","type":"journal-article","created":{"date-parts":[[2014,12,23]],"date-time":"2014-12-23T00:29:18Z","timestamp":1419294558000},"page":"e006462","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":89,"title":["Epidemiology and outcome of adult out-of-hospital cardiac arrest of non-cardiac origin in Osaka: a population-based study"],"prefix":"10.1136","volume":"4","author":[{"given":"Tetsuhisa","family":"Kitamura","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kosuke","family":"Kiyohara","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomohiko","family":"Sakai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Taku","family":"Iwami","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chika","family":"Nishiyama","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kentaro","family":"Kajino","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tatsuya","family":"Nishiuchi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yasuyuki","family":"Hayashi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yusuke","family":"Katayama","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazuhisa","family":"Yoshiya","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takeshi","family":"Shimazu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2014,12,22]]},"reference":[{"key":"2024051512583772000_4.12.e006462.1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.110.970897"},{"key":"2024051512583772000_4.12.e006462.2","doi-asserted-by":"publisher","DOI":"10.1161\/CIR.0b013e3181fdf7aa"},{"key":"2024051512583772000_4.12.e006462.3","doi-asserted-by":"publisher","DOI":"10.1016\/j.resuscitation.2010.08.021"},{"key":"2024051512583772000_4.12.e006462.4","unstructured":"Japan Resuscitation Council. 2010 Japanese guidelines for emergency care and cardiopulmonary resuscitation. 1st edn.
