Visualizing the Intellectual Structure of Electronic Health Research: A Bibliometric Analysis

The aim of this study is to detect the evolutionary track of the electronic health from its birth to the present, and then analyze its foundational knowledge and research hotspots. We conducted a bibliometric analysis on the 3085 literatures data collected from the Web of Science core data collection in 1992–2017. We used several bibliometric tools such as CiteSpace and Netdraw to complete time-and-space analysis and keywords co-occurrence network analysis. This research can provide important academic reference for international electronic health and medical informatics researchers.
