基于CiteSpace的人工智能在ICU中应用的研究的可视化分析

Visual Analysis of Research on the Application of Artificial Intelligence in ICU Based on CiteSpace

摘要: 目的：对人工智能在ICU中应用领域的研究现况、热点及发展趋势进行可视化分析。方法：以中国知网(CNKI)、万方数据库(WanFang Database)、维普(VIP)、WOS等为数据源，检索2000年1月1日~2025年10月31日有关人工智能在ICU中应用研究的文献，采用CiteSpace软件对文献年发文量、发文机构、关键词等进行可视化分析。结果：国内外人工智能在ICU中应用的研究呈现持续增长趋势。英文文献的发文量和中心性均高于中文文献，发文量最多的是哈佛大学(78篇)，中心性指数最高的是哈佛大学医学附属机构(0.20)。中文文献发文量排名前10位的机构发文量均低于10，中心性指数均为0。国内研究热点集中于预测模型、危险因素、列线图等方面，“machine learning (机器学习)”“intensive care unit (重症监护室)”“mortality (死亡)”是国外的研究热点。结论：AI作为一门新技术科学，在ICU中的应用已受到广泛关注。国内外人工智能在ICU中应用的研究呈快速增长趋势，我国的研究呈现良好态势，但发文量较少，仍需加强国际合作，深入研究。

Abstract: Objective: This study aims to conduct a visual analysis of the research status hotspots and development trends of artificial intelligence in the field of ICU applications. Method: With CNKI, WanFang Database, VIP and WOS as data sources, retrieve the literature on the application and research of artificial intelligence in ICU from January 1, 2000 to October 9, 2025, and use CiteSpace software to visually analyze the annual volume of literature, issuing countries, institutions, authors, keywords, etc. Results: The applied research of artificial intelligence in ICU at home and abroad shows a continuous growth trend. The volume and centrality of English literature are higher than those of Chinese literature. Harvard University (78 articles) has the highest number of articles, and the highest centrality index is Harvard Medical Affiliate (0.20). The top 10 institutions in the volume of Chinese literature are all below 10, and the centrality index is 0. Domestic research hotspots focus on predictive models, risk factors, line charts, etc., “machine learning”, “intensive care unit” and “mortality” are foreign research hotspots. Point. Conclusion: As a new technology science, the application of AI in ICU has received wide attention. The research on the application of artificial intelligence in ICU at home and abroad is growing rapidly. China’s research is showing a good trend, but the volume of articles is small, and it is still necessary to strengthen international cooperation and in-depth research.
