基于CiteSpace的脑卒中就医延迟可视化分析

目的 直观展现近10年国际脑卒中就医延迟研究态势，为国内脑卒中就医延迟研究提供参考。方法 以2008-2018年Web of Science数据库中收录的脑卒中就医延迟相关文献为基础，运用CiteSpace软件进行可视化分析。结果 国际脑卒中就医延迟领域的研究文献稳步增长；研究力量主要集中在美国；研究热点主要集中在卒中治疗方法、就医延迟风险因素等方面；研究前沿主要集中在血管内治疗、质量改进研究等方面。结论 未来对于脑卒中就医延迟的研究，应加强国家之间的相互合作，聚焦国际高频引文，深入探索国际研究热点。

Visualization analysis of research on pre- and in-hospital delay of stroke based on CiteSpace

Objective To summarize the international research on pre- and in-hospital delay of stroke and to provide references for related study in China. Methods Data on pre- and in-hospital delay of stroke from 2008 to 2018 were downloaded from Web of Science. CiteSpace software was used for visualization analysis. Results The international research on pre- and in-hospital delay of stroke has grown steadily. The main research country was the United States. The hot research topics included thrombolysis, risk factors and other related fields. The research front focused on endovascular treatment, quality improvement and so on. Conclusion In the future, research on pre- and in-hospital delay of stroke should strengthen mutual cooperation between countries, focus on international high-frequency citations, and explore international research hotspots.
