基于CiteSpaceV计量学分析的国内护理信息学的知识图谱研究

Knowledge graph of nursing information based on CiteSpaceV bibliometric analysis in China

目的利用可视化数据分析软件,探寻国内护理信息学研究领域的热点及发展前沿,探讨近10年护理信息学的发展演化,总结未来趋势及挑战,为今后展开进一步的研究提供科学及客观的参考依据。方法基于CNKI数据库进行主题检索,利用CiteSpaceV软件对2007年数据库中收录的护理信息学文献进行分析,绘制学科知识图谱,对整体研究概况,研究热点和研究趋势进行综合分析及可视化展示。结果在CNKI数据库中共检索到文献1 828篇,筛查后最终纳入1 488篇有效文献。将文献格式转换后导入CiteSpaceV软件,进行高频关键词进行聚类分析,剖析热点关键词的中心思想,结果显示近10年研究热点为:信息技术与临床护理实践交互融合;护理信息管理系统的设计与优化;护理信息教育体系模式的探索;护理信息素养、信息能力的前期调查及培训模式初探4个方面。通过构建突现词分布图可知,护理信息研究前沿正在不断深入细化至数据挖掘,强调患者报告结局,重视患者参与和体验的延续护理为现阶段研究趋势。结论国内护理信息学研究热点已经形成,但在国内在护理信息领域内合作性和研究间的关联性还有所欠缺。未来应从政策、技术、教育、科研为切入点对这些研究热点领域持续挖掘,在更加具体的项目上展开研究。

Objective To explore the research hotspots and development frontier of nursing information in China by utilizing the visual data analysis software to explore the evolution of nursing information nearly 10 years and summarize the future trend as well as challenges so as to provide a scientific and objective reference for carrying out further research. Methods We implemented subject search in China National Knowledge Infrastructure (CNKI), and analyzed the literatures on nursing information published in 2007 by using CiteSpaceV software, and drew a knowledge graph to comprehensively analyze and visually show the overall research overview, research hotspots and research trend. Results A total of 1 828 literatures were searched in CNKI and 1 488 effective literatures were included after screening. The literatures were imported into CiteSpaceV after transforming format. And then, we carried out the cluster analysis for high-frequency keywords to analyze the central idea of hotspot keywords. Results showed the research hotspots nearly 10 years included four aspects involving information technology integrating clinical nursing practice, design and optimization of nursing information management system, exploration of nursing information education system models, early investigation on nursing formation accomplishment and information ability and exploration of training model. The structure of burst term distribution revealed that researches on nursing information deepened and refined to data mining, emphasizing patients reported outcome, paying attention to continuous nursing which patients engaged and experienced as well as research trend at the present stage. Conclusions Research hotspots on nursing information has been formed in China. However, the relevance between cooperation and researches is still deficient in the field of nursing formation in China. In the future, these researches hotspots should be dug continually according to policies, technologies, education as well as scientific researches and researches should be carried out in specific projects.
