A Bibliometric Analysis of COVID-19 Scientific Literature From the English-Speaking Caribbean

The COVID-19 pandemic has led to a global crisis and has affected the Caribbean islands, leading to significant health and socioeconomic consequences in this region. Efforts to mitigate the burden of this disease have led to an accelerated amount of research in the English-speaking Caribbean (ESC). This bibliometric analysis aimed to evaluate the COVID-19-related scientific literature from the ESC nations. A total of 175 articles were included and analyzed from an initial PubMed search (n = 638) for COVID-19-related scientific literature from the ESC nations published between January 1, 2020, and June 30, 2022. Microsoft Excel 2016 (Microsoft Corporation, Redmond, Washington) and the VOSviewer (version 1.6.18) were used to characterize countries, authorship, journals, affiliations, and keywords of the COVID-19-related articles. Trinidad and Tobago (38%), Jamaica (22%), Barbados (20%), and Grenada (15%) contributed to the greatest number of publications. The University of the West Indies (UWI) campuses in Trinidad and Tobago, Jamaica and Barbados, and St. George's University in Grenada were the most prolific institutions. Srikanth Umakanthan from the UWI was the most prolific author. Cureus, SN Comprehensive Clinical Medicine, and Frontiers in Public Health were the first three most productive journals; 59% of the 175 articles had either the first or last author affiliated with an institution in the ESC, and 19% of the articles were country-focused: Trinidad and Tobago (16/175), Jamaica (9/175), Barbados (5/175), and Antigua and Barbuda (2/175). Among the top themes of research, 27% were outbreak response and rearrangements, epidemiological studies (23%), clinical management (23%), and medical education (13%). Over the last two years, an interest stimulated by the pandemic has expanded the research in ESC countries. However, gaps in the knowledge exist, especially in the epidemiology of COVID-19 complications in the sub-populations of chronic non-communicable diseases, post-COVID syndrome, and the long-COVID syndrome in the region. Hence, there is enormous scope for more research across the region.
