Herein, we aimed to demonstrate community\u2010wide aggressive dissemination of\n CPR<\/jats:styled-content>\n training and evaluate temporal trends in bystander\n CPR<\/jats:styled-content>\n .\n <\/jats:p>\n <\/jats:sec>\n \n Methods and Results<\/jats:title>\n \n We provided\n CPR<\/jats:styled-content>\n training (45\u2010minute chest compression\u2013only\n CPR<\/jats:styled-content>\n plus automated external defibrillator use training or the conventional\n CPR<\/jats:styled-content>\n training), targeting 16% of residents. All emergency medical service\u2013treated out\u2010of\u2010hospital cardiac arrests of medical origin were included. Data on patients experiencing out\u2010of\u2010hospital cardiac arrest and bystander\n CPR<\/jats:styled-content>\n quality were prospectively collected from September 2010 to December 2015. The primary outcome was the proportion of high\u2010quality bystander\n CPR<\/jats:styled-content>\n . During the study period, 57\u00a0173 residents (14.7%) completed the chest compression\u2013only\n CPR<\/jats:styled-content>\n training and 32\u00a0423 (8.3%) completed conventional\n CPR<\/jats:styled-content>\n training. The proportion of bystander\n CPR<\/jats:styled-content>\n performed did not change (from 43.3% in 2010 to 42.0% in 2015;\n P<\/jats:italic>\n for trend=0.915), but the proportion of high\u2010quality bystander\n CPR<\/jats:styled-content>\n delivery increased from 11.7% in 2010 to 20.7% in 2015 (\n P<\/jats:italic>\n for trend=0.015). The 1\u2010year increment was associated with high\u2010quality bystander\n CPR<\/jats:styled-content>\n (adjusted odds ratio, 1.461; 95% CI, 1.055\u20132.024). Bystanders who previously experienced\n CPR<\/jats:styled-content>\n training were 3.432 times (95% CI, 1.170\u201310.071) more likely to perform high\u2010quality\n CPR<\/jats:styled-content>\n than those who did not.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n \n We trained 23.0% of the residents in the medium\u2010sized city of Osaka, Japan, and demonstrated that the proportion of high\u2010quality\n CPR<\/jats:styled-content>\n performed on the scene increased gradually, whereas that of bystander\n CPR<\/jats:styled-content>\n delivered overall remained stable.\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1161\/jaha.118.009436","type":"journal-article","created":{"date-parts":[[2019,1,7]],"date-time":"2019-01-07T05:15:56Z","timestamp":1546838156000},"update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":29,"title":["Community\u2010Wide Dissemination of Bystander Cardiopulmonary Resuscitation and Automated External Defibrillator Use Using a 45\u2010Minute Chest Compression\u2013Only Cardiopulmonary Resuscitation Training"],"prefix":"10.1161","volume":"8","author":[{"given":"Chika","family":"Nishiyama","sequence":"first","affiliation":[{"name":"Department of Critical Care Nursing Kyoto University Graduate School of Human Health Science Kyoto Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tetsuhisa","family":"Kitamura","sequence":"additional","affiliation":[{"name":"Division of Environmental Medicine and Population Sciences Department of Social and Environmental Medicine Graduate School of Medicine Osaka University Suita Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomohiko","family":"Sakai","sequence":"additional","affiliation":[{"name":"Department of Traumatology and Acute Critical Medicine Osaka University Graduate School of Medicine Suita Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yukiko","family":"Murakami","sequence":"additional","affiliation":[{"name":"Department of Preventive Services Kyoto University Graduate School of Medicine Kyoto Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomonari","family":"Shimamoto","sequence":"additional","affiliation":[{"name":"Department of Preventive Services Kyoto University Graduate School of Medicine Kyoto Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takashi","family":"Kawamura","sequence":"additional","affiliation":[{"name":"Kyoto University Health Service Kyoto Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takahiro","family":"Yonezawa","sequence":"additional","affiliation":[{"name":"Toyonaka City Fire Department Toyonaka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shohei","family":"Nakai","sequence":"additional","affiliation":[{"name":"Toyonaka City Fire Department Toyonaka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seishiro","family":"Marukawa","sequence":"additional","affiliation":[{"name":"Iseikai Hospital Osaka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tetsuya","family":"Sakamoto","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine Teikyo University School of Medicine Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Taku","family":"Iwami","sequence":"additional","affiliation":[{"name":"Kyoto University Health Service Kyoto Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1161\/CIR.0000000000000270"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1161\/CIR.0000000000000252"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.resuscitation.2015.07.038"},{"key":"e_1_3_2_5_2","volume-title":"2015 Japanese Guidelines for Emergency Care and Cardiopulmonary Resuscitation","author":"Japan Resuscitation Council","year":"2016","unstructured":"Japan Resuscitation Council . 2015 Japanese Guidelines for Emergency Care and Cardiopulmonary Resuscitation.
