发布时间：2019-06-10 06:10

【摘要】：目的本研究旨在通过国外医院感染相关文献的共现分析探索国外医院感染的研究热点。方法以多种英文数据库为数据来源,利用Citespace可视化软件通过引文及关键词共现网络分析方法识别国外医院感染研究热点。结果本次共现分析共纳入5986条文献,引文年轮图谱中识别出490个节点与893条连接线。形成了以Horan TC(citation counts=263)等10篇为主要代表的近二十年国际医院感染研究核心著作群;识别的研究热点为:危险因素(citation counts=513)、医院感染(citation counts=480)、流行(citation counts=288)、疾病(citation counts=268)、加护病房(centrality=0.20)、血流感染(centrality=0.18)、移植(centrality=0.13)等国际医院感染研究热点;此外,本研究还通过突现词汇发现近十年国际医院感染研究热点呈现出一定的演变规律。结论国际医院感染研究热点与我国医院感染研究热点存在一定的相似性。大数据及交叉学科可以为我国医院感染的深入相关研究提供新的思路。
[Abstract]:Objective the purpose of this study was to explore the research hotspots of hospital infection in foreign countries through the co-occurrence and analysis of related literature on hospital infection in foreign countries. Methods using a variety of English databases as data sources, Citespace visualization software was used to identify the research hotspots of hospital infection in foreign countries by citation and keyword co-occurrence network analysis. Results A total of 5986 literatures were included in the analysis, and 490 nodes and 893 connecting lines were identified in the citation ring map. The core works of international hospital infection research in the past 20 years, which are mainly represented by Horan TC (citation counts=263 and other 10 articles, have been formed. The research hotspots identified are risk factors (citation counts=513), hospital infection (citation counts=480), epidemic (citation counts=288), disease (citation counts=268), intensive care unit (centrality=0.20), blood flow infection (centrality=0.18). Transplantation (centrality=0.13) and other international research hotspots of hospital infection; In addition, by highlighting vocabulary, this study also found that the international research hotspots of hospital infection in recent ten years showed a certain evolution law. Conclusion there are some similarities between the international research hotspots of hospital infection and the research hotspots of hospital infection in China. Big data and interdisciplinary disciplines can provide new ideas for the in-depth study of hospital infection in China.
