This article examined the growth and development of ehealth research based on the headcount and analysis of the characteristics of keywords used by authors and indexers to represent their research content during 1945-2019 as indexed in the Elsevier Scopus database. The results show that although the term ehealth originated in the late 1990s, but it has become an envelope term for much older terms such as telemedicine, and its variants which originated much earlier. The keywords were spread in 27 Scopus Subject Areas, with medicine (44.04%), engineering (12.84%) and computer science (11.47%) leading while by Scopus All Science Journal Classification, Health Sciences accounted for 55.83% of the keywords and physical sciences followed with 30.62%. The rest two classifications namely social sciences and life sciences made only single digit contributions. Although the primary essence of ehealth was how to meet health needs, the work of engineers who either initially deployed telephone to meet their health needs or, and, computer scientists, who addressed the need to design technologies for medical services is very significant. It is concluded that ehealth is a multidisciplinary area that is attractive to researchers from all disciplines because of its sensitive focus on health, and therefore requires pooling and integrating of resources and expertise, methods and approaches.

eHealth研究的全球趋势：作者和索引器提供的关键字的分析和可视化

本文根据人数和对作者和索引者使用关键词的特征进行了分析，研究了电子健康研究的增长和发展，这些关键词代表着Elsevier Scopus数据库在1945-2019年期间的研究内容。结果表明，尽管“健康”一词起源于1990年代后期，但它已成为诸如远程医疗及其更早起源的许多更老术语的笼统术语。关键字分布在27个Scopus主题领域，其中医学（44.04％），工程学（12.84％）和计算机科学（11.47％）领先，而在Scopus All Science Journal分类中，健康科学占关键字和物理科学的55.83％其次是30.62％。其余两个分类，即社会科学和生命科学仅贡献了个位数。尽管电子医疗的主要本质是如何满足医疗需求，但是最初部署电话以满足其医疗需求的工程师或满足设计医疗服务技术需求的计算机科学家的工作非常重要。结论是，电子卫生保健是一个多学科领域，因其对健康的敏感关注而吸引了所有学科的研究人员，因此需要汇集和整合资源以及专业知识，方法和方法。满足了设计医疗服务技术需求的人非常重要。结论是，电子卫生保健是一个多学科领域，因其对健康的敏感关注而吸引了所有学科的研究人员，因此需要汇集和整合资源以及专业知识，方法和方法。满足了设计医疗服务技术需求的人非常重要。结论是，电子卫生保健是一个多学科领域，因其对健康的敏感关注而吸引了所有学科的研究人员，因此需要汇集和整合资源以及专业知识，方法和方法。
