Consequences of the COVID-19 Pandemic on the Mental Health of Nurses in the Spanish Out-of-hospital Emergency Service

Objective: To analyse the impact of the COVID-19 pandemic on the mental health of nurses in Spanish out-of-hospital Emergency Services, identifying predictor factors of greater severity.

Method: A multicentre cross-sectional descriptive study was designed, including all nurses working in any Spanish out-of-hospital Emergency Services between 01/02/2021 and 30/04/2021. The main outcomes were the level of depression, anxiety and stress assessed through the DASS-21 scale. Sociodemographic, clinical, and occupational information was also collected. Univariate and multivariate analyses were conducted to determine possible associations between variables.

Results: The sample included 474 nurses. 32.91%, 32.70% and 26.33% of the participants had severe or extremely severe levels of depression, anxiety and stress, respectively. Professionals with fewer competencies to handle stressful situations, those who had used psychotropic drugs and/or psychotherapy on some occasion before the pandemic onset, or those who had changed their working conditions presented more likelihood of developing more severe levels of depression, anxiety and/or stress.

Conclusion: Nurses in Spanish out-of-hospital Emergency Services have presented medium levels of depression, anxiety and stress during the pandemic. Clinical and occupational factors have been associated with a higher degree of psychological distress. It is necessary to adopt strategies that promote professionals' self-efficacy and mitigate the triggers of negative emotional states.
