Nurses' health during the COVID-19 pandemic in Switzerland: A longitudinal study with mixed methods design The COVID19 pandemic has had a significant impact on healthcare systems worldwide. Nurses have played a crucial role in responding to the crisis, often at the expense of their own health and wellbeing. The aim of the study was to investigate the physical and mental health status as well as the resources of certified nurses during the pandemic, in German-speaking Switzerland. In a longitudinal study with a mixed methods design, data were collected among nurses from acute hospitals between 2021 and 2022 using a questionnaire survey and focus group interviews. The data were analysed using multiple regression analysis, knowledge mapping and the Neuman system model. The results show improvements in health, quality of life and job satisfaction, and a decrease in stress; whereby influencing extrapersonal factors are, among others, reorganisations within hospitals with the active involvement of nurses. On the interpersonal level, support from managers or colleagues proved helpful. At the intrapersonal level, the recognition of the nurses' competencies was deemed particularly important, to help them to remain healthy during the pandemic. Increased recognition, participation, training and career opportunities as well as flexible working models need to be implemented in the long term to ensure a sustainable improvement of the health and well-being of nurses.
