Investigating the evolution of COVID-19 research trends and collaborations in Southeast Asia: A bibliometric analysis

BACKGROUND AND AIMS: The publications on COVID-19 have tremendously increased. Thus, there is a need to summarize and curate this evidence from the literature. This study determined the characteristics and trends of published articles about COVID-19 in Southeast Asia (SEA) through a bibliometric analysis.

METHODS: A systematic review of literature on COVID-19 in SEA countries was performed using the Scopus database from 2020 to August 2021. Bibliometric information was obtained from Scopus and network visualization was conducted using VOSviewer software.

RESULTS: A total of 706 articles were obtained in this study. The number of publications increased exponentially from 2020 up to present. Most of the research outputs were produced by authors and institutions from Malaysia, Singapore, and Thailand. The other countries with highest cases of COVID-19 in SEA such as Indonesia and Philippines have lower scientific output in this field. GDP, research and development expenditure, number of researchers and physicians, and international collaborations were significantly correlated to research productivity in COVID-19 in SEA.

CONCLUSION: This study showed the trends and gaps for research in SEA and the facilitators of research productivity in COVID-19. SEA countries should consider increasing the support for COVID-19 research to generate knowledge that can be used in controlling COVID-19 in the region.
