There is evidence that harm to the mental health of healthcare workers has occurred during the pandemic caused by COVID-19. The burnout syndrome is a form of exhaustion that occurs in occupational settings and is a condition caused by long-term stress in the workplace. The objectives of this systematic review of observational studies were to present data from research into the prevalence of burnout syndrome in healthcare workers during the COVID-19 pandemic and observe its prevalence among frontline workers. The search was conducted on the MEDLINE, LILACS, and Embase databases from 2019 to May of 2021 and returned 538 publications, which underwent a two-stage process of selection by independent peers, resulting in selection of a sample of 29 articles. Data were then extracted and synthesized for presentation in narrative form. Cross-sectional designs were more prevalent (n = 26) than longitudinal studies (n = 3). The sample included research from 19 different countries, with one Brazilian study. A wide range of different instruments were administered by study authors to assess burnout syndrome, the most common of which was the Maslach Burnout Inventory (n = 13). The prevalence of burnout syndrome in the studies varied from 76 to 14.7%. Data on the relationship between development of burnout syndrome and working on the frontline were controversial. The lack of standardization of burnout syndrome assessment was a source of considerable difficulty, compromising comparability of the results, and should therefore be targeted for improvement by researchers. We suggest that more investigations should be conducted into prevalence and the associated factors of risk and protection.
