Mapping Research Trends of Blockchain Technology in Healthcare

Abstract

Disruptive technology, blockchain is propelling a technological intervention in healthcare due to its unique features and advantages. The healthcare industry is migrating to Health 4.0. Therefore, peer-to-peer (P2P) transactions in a decentralized and distributed manner make blockchain more lucrative to serve the needs of the healthcare industry of today. The revolutionary system blockchain has been discussed in the field of healthcare over the past five years. Hence, a systematic investigation of the existing body of knowledge concerning blockchain research in the healthcare domain is essential. The motivation of this study is to support further study based on the current research trend analysis through graphical visualization and analysis of the bibliographic material. Therefore, this study maps the expansion of scientific and academic research conducted concerning blockchain relevant to healthcare by utilizing a bibliometric analytic method to understand the state of the art. Bibliometric statistics have been utilized to analyze current scientific articles published in the Scopus database from 2016 to 2019. In addition, an overview of the publication trends over the first three months of 2020 has been undertaken to understand the research trend for the current year so far. The study serves the purpose of mapping research development trends in this area. The outcome discovered some beneficial insights such as the yearly trend of publications, top listed authors, institutes, countries and publishers from around the world. Moreover, this paper assists scholars to develop a theoretical framework to provide a primary source of reference in this field for further study of blockchain technology in the healthcare domain.

“…Scopus is a core scientific database recognized by Elsevier and has around has around 70 million articles [9], [10]. This study evaluates data retrieved from the Scopus database.…”

“…Co-authorship refers to authors joint publication [9], [11]. The bibliometric network of VOSviewer represents the linkage among scholars, universities, countries, or regions depending on the number of papers published together authors in the coauthorship investigation section.…”

“…Between Germany and China, the link strength is 1. The link value is equally proportionate to the numerical link strength; a higher link value means higher link strength [9], [12].…”

“…Also, from each document, only the principal author has been given attention. Besides, Due to lack of information on author keywords, the Co-occurrence analysis analyzed 84% of keywords from 63 documents [9], [17]. Bibliometric analysis needs to be conducted regularly as the finding changes within a brief period with the availability of new articles on a particular research area [11].…”

Bibliometric Analysis of the Blockchain Scientific Evolution: 2014–2020

“…Joao [35] employed R to analyze Blockchain technology's recent progress, limitations, and future trends. Anjum et al [36] used VOSviewer to draw an expanded diagram of scientific and academic research on Blockchain-related healthcare studies to identify research trends. Wang and Su [37] analyzed Blockchain's development status in the energy field using the bibliometric method.…”
