Health science research barriers and facilitators in the midst of the COVID-19 crisis: scoping review

Objective: The COVID-19 pandemic has imposed a great challenge on health research because of the pressing need to respond promptly and effectively to this crisis situation. It is important to offer a high level perspective of the main barriers and facilitators found when conducting health science studies during the COVID-19 crisis and to discuss the research initiatives suggested by global, regional or local health research authorities.

Materials and methods: A systematic scoping review was carried out. A literature search was conducted in the Medline, Cochrane Library, Lilacs and Google Scholar databases. Original research studies, review and opinion articles and editorials available in full text published in Spanish, English or Portuguese between January 2020 and May 2021 were included. Two authors working independently selected the papers and collected the data. The barriers and facilitators identified were described and organized in four categories according to the literature: sociocultural, administrative, organizational and methodological. Official documents and communications from global, regional and local health and research authorities were also included. Results are presented in narrative and table form.

Results: Overall, 26 documents were selected for data analysis and synthesis. The barriers most frequently mentioned in the literature include issues with access to participants, ethics committees paperwork, biological risk for the researchers, and lack of inter and intra-institutional coordination. On the other hand, the facilitators identified include the adoption of on-line solutions, cooperative work among research actors, and a more flexible informed consent process. Regarding the initiatives disseminated by health and research authorities, four strategies were identified: prioritization of research questions, cooperation and inclusion promotion, fight against infodemia, and strengthening of the methodological quality of the studies.

Conclusions: Continued cooperation and interoperability among institutions, countries and disciplines to facilitate future research processes is a challenge in the context of the pandemic; similarly, it is now important to maintain open science and funding of cooperative studies when other priorities emerge. Likewise, there is an evident need to develop and sustain efficient information management systems to help with decision-making. Ongoing review of the effects of the pandemic on health research practice is needed in order to gain comprehensive insights of what we need to learn as a society from this crisis.
