Ethical conflict and its psychological correlates among hospital nurses in the pandemic: a cross-sectional study within Swiss COVID-19 and Non-COVID-19 wards

Background: during the Covid-19 pandemic, nurses experienced increased pressure. Consequently, ethical concerns and psychological distress emerged. This study aimed to assess nurses' ethical conflict, resilience and psychological impact, and compare these variables between nurses who worked in Covid-19 wards and nurses who did not. Methods: design Multicentre online survey. Setting Multi-site public hospital; all nursing staff were invited to participate. The survey included validated tools and a novel instrument to assess ethical conflict. Spearman's rho coefficient was used to assess correlations between ethical conflict and psychological distress, logistic regressions to evaluate relationships between nurses' characteristics and outcome variables, and the Mann-Whitney/t-test to compare groups. Results: 548 questionnaires out of 2039 were returned (275 = Covid-19; 273 = non-Covid-19). We found a low-moderate level of ethical conflict (median = 111.5 [76-152]), which emerged mostly for seeing patients dying alone. A moderate and significant positive correlation emerged between ethical conflict and psychological distress rs (546) = 0.453, p < 0.001. Nurses working in Covid-19-ICUs (OR = 7.18; 95%CI = 3.96-13.01; p < 0.001) and Covid-19 wards (OR = 5.85; 95%CI = 3.56-9.6; p < 0.001) showed higher ethical conflict. Resilience was a protective factor for ethical conflict. Conclusions: ethical conflict was significantly linked to psychological distress, while a higher level of resilience was found to be a protective factor. These results can be informative for nursing management in future similar crises.
