Aims and objectivesTo explore how Flemish nurses working in hospitals and home care experience their involvement in the care of patients requesting euthanasia 15 years after the legalisation of euthanasia.BackgroundEuthanasia was legalised in Belgium in 2002. Despite prior research that charted the experiences of nurses in euthanasia care before and right after legalisation in Belgium, it remains unclear how Flemish nurses currently, 15 years after the legalisation, experience their involvement.DesignA grounded theory design, using semi‐structured in‐depth interviews.MethodsWe interviewed 26 nurses working in hospitals or in home care, who had experience with caring for patients requesting euthanasia. Data were collected using a purposive sample and then a snowball sample. Data collection and data analysis were conducted simultaneously. Data were analysed by using the Qualitative Analysis Guide of Leuven. The study adhered to the COREQ guidelines.ResultsCaring for a patient requesting euthanasia continues to be an intense experience characterised by ambivalence. The nature of euthanasia itself contributes to the intensity of this care process. The nurses described euthanasia as something unnatural and planned that generated many questions and doubts. Nevertheless, most interviewees stated that they were able to contribute to a dignified end of life and make a difference, giving them a profound feeling of professional fulfilment. However, when nurses were not able to contribute to good euthanasia care, they struggled with strong negative feelings and frustrations.ConclusionAlthough the results suggest some subtle shifts in nurses' experiences over time, they do not indicate perceptions of euthanasia as a normal practice by the nurses involved.Relevance to clinical practiceThe study reveals the need for more clarification of nurses' ethical responsibility in euthanasia care and their role as moral agents.
