However, how bystander cardiopulmonary resuscitation (BCPR) composition and survival change in unwitnessed out-of-hospital cardiac arrest (OHCA) cases remains unclear. The aim of this study was to investigate (1) the changes in BCPR based on combined rescue breathing and dispatcher-assisted resuscitation; and (2) the association between changes in BCPR content and annual outcome improvement in unwitnessed OHCA cases compared to bystander-witnessed OHCA cases.\nMethod: This study involved the retrospective analysis of data for OHCA cases that were prospectively collected nationwide and population-based. OHCA cases from 2009 to 2016 were evaluated to provide a complete dataset for the analysis. The primary outcome was neurologically favorable 1-month survival.\nResults: The rate of dispatcher-assisted compression-only resuscitation increased annually. Further, there was a shift from standard resuscitation to compression-only bystander resuscitation and an increased rate of dispatcher attempts of instructions in both unwitnessed and bystander-witnessed arrest cases. In a multivariable logistic regression model for cases with dispatcher attempts, the neurologically favorable 1-month survival rate of patients who experienced unwitnessed arrest in the dispatcher-assisted standard BCPR group was higher than that in the dispatcher-assisted compression-only BCPR group (adjusted odds ratio 1.23 [95% confidence interval: 95%CI 1.03–1.46]). Further, the outcome improvement for 8 years in the standard BCPR group was more prominent than that in the compression-only BCPR group (p < 0.01, interaction test). The neurologically favorable 1-month survival rate of patients with unwitnessed arrest in the voluntarily-initiated standard BCPR group without the dispatcher’s attempt of instructions was higher than that in the voluntarily-initiated compression-only BCPR group (adjusted odds ratio 1.21 [95%CI 1.01–1.52]). However, the outcomes improved similarly in both groups. The differences between standard and compression-only resuscitation were less prominent in patients with bystander-witnessed OHCA, particularly in cases without dispatcher instructions.\nConclusions: Compression-only resuscitation may not be the ideal management strategy for unwitnessed OHCA when dispatchers attempt resuscitation instructions.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_full_name_3":{"attribute_name":"著者（英）","attribute_value_mlt":[{"names":[{"name":"Tomoyuki Ushimoto","nameLang":"en"}]},{"names":[{"name":"Hideki Morita","nameLang":"en"}]},{"names":[{"name":"Yukihiro Wato","nameLang":"en"}]},{"names":[{"name":"Hideo Inaba","nameLang":"en"}]}]},"item_10001_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.57457/0002000007","subitem_identifier_reg_type":"JaLC"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"金沢医科大学医学会","subitem_publisher_language":"ja"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2436-6994","subitem_source_identifier_type":"EISSN"}]},"item_10001_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"牛本 知孝","creatorNameLang":"ja"},{"creatorName":"ウシモト トモユキ","creatorNameLang":"ja-Kana"}]},{"creatorNames":[{"creatorName":"盛田 英樹","creatorNameLang":"ja"},{"creatorName":"モリタ ヒデキ","creatorNameLang":"ja-Kana"}]},{"creatorNames":[{"creatorName":"和藤 幸弘","creatorNameLang":"ja"},{"creatorName":"ワトウ ユキヒロ","creatorNameLang":"ja-Kana"}]},{"creatorNames":[{"creatorName":"稲葉 英夫","creatorNameLang":"ja"},{"creatorName":"イナバ ヒデオ","creatorNameLang":"ja-Kana"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2023-08-19"}],"displaytype":"detail","filename":"48(1)33-42.pdf","filesize":[{"value":"2.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"url":"https://kanazawa-med.repo.nii.ac.jp/record/2000007/files/48(1)33-42.pdf"},"version_id":"5cd92f92-0490-4190-93cf-d3f737e75c55"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"bystander resuscitation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"dispatcher-assisted resuscitation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"compression-only resuscitation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"out-of-hospital cardiac arrest","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"basic life support","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Association of Dispatcher-Assisted Compression-Only Resuscitation with Survival Rate in Unwitnessed Out-of-Hospital Cardiac Arrest: A Temporal Trend and Analyses of 8-Years Trend","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Association of Dispatcher-Assisted Compression-Only Resuscitation with Survival Rate in Unwitnessed Out-of-Hospital Cardiac Arrest: A Temporal Trend and Analyses of 8-Years Trend","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"5","path":["1692238438793"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-08-19"},"publish_date":"2023-08-19","publish_status":"0","recid":"2000007","relation_version_is_last":true,"title":["Association of Dispatcher-Assisted Compression-Only Resuscitation with Survival Rate in Unwitnessed Out-of-Hospital Cardiac Arrest: A Temporal Trend and Analyses of 8-Years Trend"],"weko_creator_id":"5","weko_shared_id":-1},"updated":"2024-10-04T00:25:39.286912+00:00"}
