This qualitative study investigated the personal and professional stances of 40 health and social care professionals confronted with assisted suicide of older persons living in nursing homes or supported by social welfare or home care and support services in French-speaking Switzerland. Requests of assisted suicide triggered questions with regard to the professional mission, the quality of accompaniment, values, and ethical principles. Four types of stances emerged from the analysis performed according to the principles of the grounded theory: favorable in principle, (...) professional compromise, personal compromise, and opposed in principle. Each stance results from the combination of several dimensions: personal or professional concordance or compatibility with assisted suicide; implication in, and impact of, the process; appreciation of the process; and satisfaction with the resources at disposal. The differentiated stances adopted by professionals depend largely on their way of interpreting their mission, deontology, and the relationship to the older person. (shrink)
