Advancements in Cyber Security and Information Systems in Healthcare from 2004 to 2022: A Bibliometric Analysis

The main goals of the multifaceted healthcare system were to prevent, identify, and treat illnesses or conditions that affect human health. As the usage of IT in healthcare increased, the complexities in managing the IT infrastructure also increase, emphasizing the need of robust cyber security systems. The study aims to emphasize the advancements made in cyber security and information systems in healthcare, based on bibliometric analysis. 5,487 document's metadata was obtained from Scopus and data was analyzed using Vos Viewer. Ranking of articles was done with average yearly citations of the publications. Bibliometric analysis was performed based on “bibliographic coupling of countries”, “co-occurrence of all keywords”, “author-based co-authorship”, and “term co-occurrence based on text data”. It was found that United States had the maximum publications (1337). “Department of Information Systems and Cyber Security, The University of Texas at San Antonio, United States” is the most influential organization with 159 publications. IEEE Access is the most preferred platform for publication related to cyber security and information systems in healthcare (231 publications). 167 publications have received more than 100 citations. Choo K. K.R. is the most influential author with 185 publications.
