Introduction and purpose of the research: the authors, members of the End-of-Life Care group at the University of La Laguna (CUFINVIDA), seek to identify areas of improvement concerning end-of-life care, loss and grief in the professional context, from the premise that there is not enough training around this topic. Methodology: phenomenological hermeneutic research through a focus group of fifteen nurses from Ofra Delicias-Miramar primary healthcare centre in Santa Cruz de Tenerife (Spain), carried out in November 2019. Results: Four main categories are identified when delving into what mourning is: the physical space of mourning and death; meaning and context; mourning for deceased children and proposals for improvement. Conclusions: Nurses report not feeling prepared regarding grief and the process of dying. Training is scarce, and it is necessary to consider and reflect on how nurses carry out diagnoses and establish objectives and interventions for people at the end of life or in the mourning process.
