Continuous Deep Sedation Until Death Is Not an Alternative to Assisted Suicide in Palliative Care Units in the French-Speaking Part of Switzerland: A Multicentre Qualitative Study Based on Interviews With Physicians.

Abstract

Background: According to the European Association for Palliative Care, decisions regarding palliative sedation should not be made in response to a request for death. However, several studies show that continuous deep sedation until death (CDSUD) – a particular form of sedation – has been considered as an alternative to active assisted dying in some countries. In Switzerland, where assisted suicide is decriminalized and CDSUD is not legally regulated, no studies have comprehensively investigated if they might be correlated. Our study aimed to identify and describe the experience among palliative care physicians of CDSUD as an alternative to assisted suicide in the French-speaking part of Switzerland.Methods: We performed an exploratory multicentre qualitative study based on interviews with physicians working in palliative care institutions in the French-speaking part of Switzerland and conducted linguistic and thematic analysis of all interview transcripts. The study is described in accordance with COREQ criteria.Results: We included 10 interviews conducted in four palliative care institutions. Our linguistic analysis shows four main types of sedation, which we called ‘rapid CDSUD’, ‘gradual CDSUD’, ‘temporary sedation’ and ‘intermittent sedation’. CDSUD (rapid or gradual) is not considered an alternative to assisted suicide. In contrast, ‘temporary’ or ‘intermittent sedation’, although not medically indicated, is sometimes introduced in response to a request for assisted suicide. This is due to the impossibility of carrying out an assisted suicide at home (e.g., home transfer is impossible or the patient’s wish not to traumatize the family).Conclusion: These preliminary results can guide clinical, ethical, linguistic and legal reflection in this field and be used to explore this question more deeply at the national and international levels in a comparative, interdisciplinary and multiprofessional approach. They can also be useful to update Swiss clinical guidelines on palliative sedation in order to include specific frameworks on various sedation protocols and sedation as an alternative to assisted suicide. Potential negative impacts of considering palliative sedation as an alternative to assisted suicide should be nuanced by open and honest societal debate.
