基于WOS的中美医学信息学研究热点对比分析

摘要

以Web of Science(WOS)核心合集为数据源,检索中、美两国近10年在医学信息学领域发表的文献,采用共词分析方法与TDA软件和SPSS 20.0软件对数据进行清理和聚类分析,并通过Ucinet和NetDraw对关键词的分布进行可视化分析,总结两国在医学信息学领域的研究热点.经聚类和可视化分析发现,两国医学信息学研究既存在一致性也存在差异性,一致性表现在计算机技术在医院管理和临床诊疗中的应用,差异性表现在美国医学信息学科整体发展水平较高、对医学信息和数据的利用更为充分、医学信息学教育体系更为完善、循证医学研究水平及层次较高.%Papers on medical informatics published in China and USA in the past 10 years were analyzed by co-word analysis using TDA and SPSS 20.0 respectively with Web of Science-covered core collection as the data source and the distribution of key words in the papers was analyzed by Ucinet and NetDraw respectively to mine the research hotspots, which showed consistencies and differences in medical informatics of the two countries.The con-sistencies were demonstrated in application of computer technologies in hospital management and clinical diagnosis and treatment while the differences were revealed in higher level of medical informatics, fuller use of medical infor-mation and data, the more perfection of medical informatics education system, and the higher level of EBM research in USA than in China.
