Purpose: The current study aims at exploring the theme – wearable devices in healthcare services from 2008 to 2021. It intends to identify the most prominent sources, authors, affiliations, countries, documents, words and trend topics. Methodology: Total 204 records have been extracted from Scopus after applying inclusion and exclusion criteria, and analysed by using biblioshiny software of R-package. Findings: Results of bibliometrix analysis show the prominent sources in ‘wearable devices & healthcare’ search are IEEE Access and Sensors (Switzerland). Moreover, Lee S. and Shen J. are found be the most productive and prolific authors, King Saud University is leading institutions in producing the articles, China, South Korea, India and USA are identified as the most productive countries and Network Security, Cryptography, Deep Learning, Healthcare Application and Healthcare System are found to be the trending topics and themes in the year 2021. Originality: This study presents the deep analytics regarding wearable devices in healthcare services and it also suggests useful future research avenues and insights for researchers and practitioners.

The purpose of the paper is to identify the links and connections among main themes of the search i.e., Mobile Technologies, Service Quality and Healthcare. It also aims at identifying the valuable contributions from authors, journals, countries, and institutions in the searched area. Data has been extracted from Scopus database and it covers the timeline from 2005 to 2021. The final documents (n=245) have been analysed through VOSviewer software and MS Excel. Results show that Guo, X., International Journal of Medical Informatics, Harbin Institute of Technology, China and United States are top performing author, journal, institution and countries respectively. According to the results for collaborations and associations, Bhuiya A., United States and Mobile Healthcare are the most prominent author, country and keyword with highest score of total link strength (TLS). Findings suggested important and valuable avenues for future research directions in terms of underperforming countries, under-utilized subject areas and under-explored themes (keywords). This study, to best of our knowledge, is the first of its kind in mapping the literature of combined themes (Mobile Technologies, Service Quality and Healthcare).
