Professionals working in long term facilities (LTF) for older adults in some French-speaking states in Switzerland face challenging issues related both to suicide prevention (SP) and assisted suicide (AS). On the one hand, 80-84 years old adults have the highest suicide rates (29/100’000, OFS, 2023). However, Switzerland has no national suicide prevention strategy and suicide prevention activities among older adults are very scarce. On the other hand, Right-to-die associations are allowed to assist older people with suicide within LTF provided that certain requirements are fulfilled. Professionals working within LTF do not perform the act that causes the death nor they provide the mean, but they are involved in the process. For example, they might assess the capacity or the unimpaired judgment. Requests of AS generally represents a disruption in the professional relationship to the patient and in the organizational functioning which engenders stress and reflexivity. For example, professionals have to deal with the question: How is a request of assisted suicide to be interpreted and treated? As a manifestation of suicidal distress or as the expression of a self-determined wish/decision? Drawing from a qualitative study (40 interviews with professionals in LTF) and an ethnographic study (83 interviews, and 58 participant observations of a variety of actors involved in the process -professionals, patients, significant others, etc.), the presentation will point out some challenges and issues professionals face when an older adult request assisted suicide. Moreover, the presentation will illustrate some of the ways in which professionals react and respond. These are based on a number of factors: their personal and professional values and attitudes towards assisted suicide; consideration of institutional guidelines and legal and ethical frameworks; and the social scripts relating to suicide prevention and assisted suicide at hand in their professional and social context. Education and support should be provided to health and social care professionals to promote informed dealing with such a complex issue.
