我国医疗影像云发展现状研究--基于文献计量学分析

Research on the Development of Medical Image Cloud in China--Based on Bibliometric Analysis

目的通过分析国内与医疗影像云相关文章的发布情况,以期对医疗影像云的研究与应用有所指导和参考。方法采用循证医学定性系统综述方法,对中国知网,维普和万方数据库进行主题词检索,检索时间为从建库至2020年3月,分别从研究方法质量评价、发表期刊、发表年份、作者机构、核心作者、基金分布、研究内容等方面进行分析。结果在纳入的85篇文献中,文献数量总体呈上升趋势,在2017年达到了发表量的峰值22篇,近两年发文量又有所回落,其中2018年发文量的回落比达45.5%,很有可能是此方向相关研究者们的关注度略有下降;分析这85篇文献中所涉及的作者,根据普赖斯定律显示尚未形成核心作者;从发文量来看,广东省处于领先地位,其次依次是北京市、江苏省、上海市;从提取的高频关键词分析,出现频率最高的是“医学影像信息系统”一词,其次依次为云计算、云存储、云平台;从基金资助来看,资金资助文献占总纳入文献的31.7%,资助项目中省级课题项目较多,占总资助文献的45.71%。结论我国有关医疗影像云的研究总体数量较少,且研究地点主要集中在广东、北京等发达地区,故本文呼吁相关单位进一步加强对医疗影像云(尤其在中西部等不发达地区)的研究与应用。

Objective To provide some guidance and reference for the research and application of medical image cloud through analyzing the release of articles related to medical image cloud in China.Methods The qualitative and systematic review method of evidence-based medicine was used to search the CNKI,VIP and Wanfang Databases from the establishment of the database to March 2020,and the quality evaluation of research methods,journals,years of publication,authors’organizations,core authors,fund distribution and research content were analyzed.Results Among the 85 included literatures,the number of literatures showed an overall upward trend,reaching the peak of 22 published articles in 2017.In the past two years,the number of published articles has fallen again,and the percentage of published articles in 2018 had fallen by 45.5%,which was probably due to a slight decline in the attention of researchers in this direction.Based on the analysis of the authors involved in the 85 literatures,according to Price’s law,no core authors had been formed.From the perspective of the volume of publications,Guangdong took the lead,followed by Beijing,Jiangsu and Shanghai.Based on the analysis of extracted high-frequency keywords,medical image information system was the most frequent word,followed by cloud computing,cloud storage and cloud platform.In terms of fund support,31.7%of the total literatures were funded by funds,and the number of provincial projects was more,accounting for 45.71%of the total funded literatures.Conclusion In China,the number of research on medical image cloud is relatively small,and the research sites are mainly in Guangdong,Beijing and other developed areas.Therefore,this paper calls on relevant units to further strengthen the research and application of medical image cloud(especially in the underdeveloped areas such as the central and western regions).
