One of the main causes of death is out-of-hospital cardiac arrest (OHCA), which has a poor prognosis and poor neurological outcomes. This phenomenon has attracted increasing attention. However, there is still no published bibliometric analysis of OHCA. This bibliometric analysis of publications on OHCA aimed to visualize the current status of research, determine the frontiers of research, and identify future trends. Publications on OHCA were downloaded from the web of science database. The data elements included year, countries/territories, institutions, authors, journals, research areas, citations of publications, etc. Joinpoint regression and exponential models were used to identify and predict the trend of publications, respectively. Knowledge domain maps were applied to conduct contribution and collaboration, cooccurrence, cocitation, and coupled analyses. Timeline and burst detection analysis were used to identify the frontiers in the field. A total of 3 219 publications on OHCA were found from 1998 to 2022 (average annual percentage change = 16.7; 95% CI 14.4, 19.1). It was estimated that 859 articles and reviews would be published in 2025. The following research hotpots were identified: statement, epidemiology, clinical care, factors influencing prognosis and emergency medical services. The research frontier identification revealed that 7 categories were classified, including therapeutic hypothermia, emergency medical services, airway management, myocardial infarction, extracorporeal cardiopulmonary resuscitation, stroke foundation and trial. The burst detection analysis revealed that percutaneous coronary intervention, neurologic outcome, COVID-19 and extracorporeal cardiopulmonary resuscitation are issues that should be given continual attention in the future. This bibliometric analysis may reflect the current status and future frontiers of OHCA research.
心脏骤停（OHCA）是导致死亡的主要原因之一，其预后不良，神经结局较差。这一现象引起了越来越多的关注。然而，目前还没有关于 OHCA 的已发表文献计量学分析。本研究对 OHCA 相关出版物进行文献计量学分析，旨在可视化当前研究状况，确定研究前沿，并识别未来趋势。从 Web of Science 数据库中下载 OHCA 相关出版物。数据元素包括年份、国家/地区、机构、作者、期刊、研究领域、出版物引用等。使用 Joinpoint 回归和指数模型分别识别和预测出版物趋势。知识领域图谱用于进行贡献和合作、共现、共被引和耦合分析。时间线和突发检测分析用于识别该领域的前沿。从 1998 年至 2022 年，共发现 3219 篇 OHCA 相关出版物（年均百分比变化率为 16.7%；95%CI 为 14.4%~19.1%）。预计 2025 年将发表 859 篇文章和综述。确定了以下研究热点：声明、流行病学、临床护理、影响预后的因素和急救医疗服务。研究前沿识别表明，有 7 个类别被分类，包括治疗性低温、急救医疗服务、气道管理、心肌梗死、体外心肺复苏、中风基础和试验。突发检测分析表明，经皮冠状动脉介入治疗、神经功能结局、COVID-19 和体外心肺复苏是未来应持续关注的问题。本文献计量学分析可能反映了 OHCA 研究的现状和未来前沿。
