[Impact of SARS-CoV-2 (Covid-19) on the mental health of healthcare professionals: a systematic review.]

Background: In times of this global pandemic situation, population's mental health is compromised, especially in those groups that are at the forefront of defence against the virus such as healthcare professionals. The objective of this study was to analyze the impact of the SARS-CoV-2 outbreak on healthcare professionals' mental health.

Methods: A systematic review was carried out following the PRISMA format in Pubmed, Scopus, Web of Science, CINAHL, PsycINFO and ScienceDirect electronic databases between January and May 2020. Methodological quality was evaluated using the Joanna Briggs Institute (JBI) critical appraisal tools for non-randomized studies.

Results: A total of 13 studies were included in this review. Professionals' mental health and mental functions were compromised, being especially affected those professionals on the front line of battle against the virus. However, these stats were below the general population data. Although there is wide variability of results, medium-high levels of anxiety (26,5%-44,6%), depression (8,1%-25%), concern and insomnia are detected (23,6%-38%). Paradoxically, stress levels were below expectations (3,8%-68,3%).

Conclusions: The mental well-being of health professionals working on the front line is compromised in times of pandemic by presenting medium-high levels of anxiety, depression, nervousness and insomnia, and, to a lesser extent, stress.
