Mental health during the first wave of COVID-19 in Canada, the USA, Brazil and Italy

Background The mental health (MH) burden on healthcare practitioners (HCPs) is emerging as a significant cost of the pandemic, although few studies have compared the MH of HCPs in different countries. Methods A link to an online survey was posted in the Spring of 2020 which included questions regarding perceived impact of the pandemic; current MH symptom severity and impairment was evaluated using validated scales. Results Overall, 1315 individuals (74% female, mean age: 42.9 + 16.4) in Canada, the United States, Brazil and Italy completed the survey. Nearly 26% met diagnostic thresholds for GAD and MDD; Italian respondents reported the lowest rates of disorder. Except for Canada, non-HCPs in each country reported higher symptom severity than HCPs. Amongst the HCPs, Canadian HCPs reported the highest rates of anxiety and depression as well as increases in alcohol and cannabis use, lower levels of perceived emotional support and more worry about themselves or their loved ones contracting COVID-19. Conclusion Despite key infrastructural and COVID-19 mortality differences between the countries, the MH effects appeared to be quite similar. HCPs, with the exception of Canada, reported less impact on their mental health compared to the general population, suggesting resilience in the face of adversity.

Automated summary

The study found that despite differences in mental health among healthcare practitioners in different countries, the overall impact of the pandemic on mental health appeared to be similar. Canadian healthcare practitioners reported the highest rates of anxiety and depression, while non-healthcare practitioners in other countries reported higher symptom severity than healthcare practitioners.
