Scientometric mapping of global publication trends in health informatics domain

Abstract

Purpose: Over the last two decades, health informatics has garnered much attention with a rapid increase in the research output. This study aims to review and evaluate the global progress in the Health Informatics domain and assess the scholarly publication productivity. Design/Methodology: Based on data from the Web of Science databases, scientometric methods and knowledge visualization techniques were applied to evaluate the global trends, perform thematic analysis, identify gaps in knowledge and predict future trends of the health informatics domain from 2009 to 2021. Findings: The findings revealed that the field of Health Informatics has increased rapidly over the last decade. 3856 publications were produced from 2009 to 2021 and have gradually increased from 4.85% in 2009 to 69.63% in 2021 North American continent had the highest productivity with 63.38% global publication share out of 3856. USA (58.35%), Canada (7.62%) Australia (5.44%), and China (4.12%) were the leading countries with the highest publication productivity. Journal of The American Medical Informatics Association published by the American Medical Informatics Association is the leading journal with impact factor 3.428 (2018) and 236 publications. Harvard University was the leading position with 6.40% of publications. The United States Department of Health and Human Services is the leading funding body it has funded 782 publications. Conclusions: These findings will provide evidence of the current status and trends in Health Informatics all over the world, thus, helping scientific researchers and policymakers understand the panorama of Health Informatics and predict the dynamic directions of research.
