Healthcare Workers and Patient Loss During the COVID-19 Pandemic: Interaction Between Grief, Viral Anxiety, and Depression

Objective Coronavirus disease-2019 (COVID-19) had a significant impact on the mental health of healthcare workers. Related assessments should be included in plans for future pandemics. We investigated the connections between grief, viral anxiety, depression, and preoccupation in the context of COVID-19 in healthcare workers, to determine which factors will need to be incorporated. Methods A total of 267 healthcare workers who had experienced the death of at least one patient during the COVID-19 pandemic were asked to respond to questionnaires assessing grief, viral anxiety, depression, loneliness, and preoccupation with COVID-19, based on their emotional state during the 2 weeks immediately after the death. Multivariate linear regression, causal mediation analysis and structural equation modeling were used to examine the psychological processes underlying grief. Results Linear regression showed that viral anxiety (beta=0.287, 95% confidence interval [CI]: 0.235-0.338, p<0.001) and depression (beta= 0.157, 95% CI: 0.073-0.241, p<0.001) had independent associations with preoccupation with COVID-19. Causal mediation analysis revealed that both viral anxiety (proportion mediated: 0.51, 95% CI: 0.37-0.66, p<0.001) and depression (proportion mediated: 0.77, 95% CI: 0.50-1.08, p<0.001) were mediators between grief and preoccupation with COVID-19. In a structural equation model, viral anxiety and depression mediated most of the effects of grief on preoccupation with COVID-19, and loneliness was a mediator between grief and depression. Conclusion Contingency plans for the next pandemic are being formulated. Effective measures to protect the mental health of healthcare workers should be included, and such measures should consist of assessments for grief, viral anxiety, depression, and loneliness.
