Global Scientific Research landscape on Medical Informatics from 2011 to 2020： Bibliometric Analysis
ABSTRACT
Background:
With emerging information and communication technology, Medical Informatics has dramatically evolved in Healthcare and Medicine. Thus, it is crucial to explore global scientific research landscape on Medical Informatics.
Objective:
This study aims to present a visual form to clarify the overall scientific research trends of Medical Informatics in the past decade.
Methods:
A bibliometric analysis of data retrieved and extracted from the Web of Science Core Collection (WoSCC) database was performed to analyze global scientific research trend on Medical Informatics, including publication year, journals, authors, institutions, countries/regions, references, and keywords, from January 1st, 2011, to December 31st, 2020.
Results:
A total of 34,742 articles related to Medical Informatics were retrieved from WoSCC between 2011 and 2020. The annual global publications increased 193.86% from 1,987 in 2011 to 5,839 in 2020. Journal of Medical Internet Research (3,600 publications , 63,932 citations) was the most productive and most high-cited journal in Medical Informatics. Bates David W (99 publications), Harvard University (1,161 publications), the USA (12,927 publications) were the most productive author, institution, and country, respectively.The co-occurrence cluster analysis of high-frequency author keywords forms four clusters: (1) artificial intelligence(AI) in healthcare and medicine; (2) Mobile health; (3) implementation and evaluation of Electronic health records (EHRs); (4) medical informatics technology application in public health. Covid-19 ranking third in 2020 was emerging themes of Medical Informatics.
Conclusions:
We summarize the recent advances in Medical Informatics in the past decade and shed light on their publication trends, influential journals, global collaboration patterns, basic knowledge, research hotspots, and theme evolution through bibliometric analysis and visualization maps. These findings will accurately and quickly grasp the research trends and provide valuable guidance for future medical informatics research.
