Psychological impact of COVID-19 on healthcare workers: prevalence systematic review

Abstract

Objective

To synthesize the prevalence of psychological and mental health outcomes among healthcare professionals who are responsible for treating patients with COVID-19.

Methods

Systematic literature review. The literature search was carried out in the PubMed, CINAHL and Scopus databases. Studies written in English, Portuguese and Spanish and that were published between December 1st 2019 and July 31st 2020 were included. The systematic review was performed using fixed-effect meta-analysis of binary data with STATA®15.0 and inverse-variance method using Freeman-Tukey double arcsine transformation.

Results

The search strategy identified 38,657 records. Only five of those studies were selected and were included in the final review corpus. The meta-analysis conducted showed that the prevalence of depression reached 27.5% (95%CI=25.9-29.3; p<0.001), the prevalence of anxiety was 26.8% (95%CI=25.1-28.5; p<0.001), that of insomnia 35.8% (95%CI=33.8-37.9; p=0.03) and the prevalence of stress amounted to 51.9% (95%CI=49.6-54.3; p<0.001). Three of the studies included in the review show that healthcare professionals have also reported significant levels of vicarious traumatization, posttraumatic stress, somatization, and obsessive-compulsive symptoms.

Conclusion

The COVID-19 pandemic is found to have a very significant psychological impact on healthcare workers and is quite likely to lead to an important prevalence of depression, anxiety, insomnia, and stress. Frontline healthcare professionals are a particularly vulnerable group and deserve special attention/ intervention.
