Could palliative sedation be seen as unnamed euthanasia?: a survey among healthcare professionals in oncology

Key messagesWhat is already known about the topic? Studies have explored the ethics of choices, such as withholding or withdrawing treatments, moral positions to euthanasia, sedation practices or evaluation of end-of-life prognosis, but none have explored, in real life, health care professionals' opinion and experience of all these aspects combined, in palliative cancer care.What this paper adds: This study highlights the discrepancy between some elements of the law and opinions of carers, along with the risk of conflict within teams and with families. It also highlights the risk of drifting towards euthanasia.Implications for practice, theory or policy: this study could lead to a multi-centric national study and could, if confirmed, add the voice of professionals to the ethical debate on end-of-life practices in France, which could be reported to the legislator. It could also lead colleagues of abroad to analyse practices in regard of their national laws on end-of-life. BackgroundIn 2016 a French law created a new right for end-of-life patients: deep and continuous sedation maintained until death, with discontinuation of all treatments sustaining life such as artificial nutrition and hydration. It was totally unprecedented that nutrition and hydration were explicitly defined in France as sustaining life treatments, and remains a specificity of this law. End- of-life practices raise ethical and practical issues, especially in Europe actually. We aimed to know how oncology professionals deal with the law, their opinion and experience and their perception.MethodsOnline mono-centric survey with closed-ended and open-ended questions in a Cancer Comprehensive Centre was elaborated. It was built during workshops of the ethics committee of the Institute, whose president is an oncologist with a doctoral degree in medical ethics. 58 oncologists and 121 nurses-all professionals of oncological departments -, received it, three times, as mail, with an information letter.Results63/ 179 professionals answered the questionnaire (35%). Conducting end-of-life discussions and advanced care planning were reported by 46/63 professionals. In the last three months, 18 doctors and 7 nurses faced a request for a deep and continuous sedation maintained until death, in response to physical or existential refractory suffering. Artificial nutrition and even more hydration were not uniformly considered as treatment. Evaluation of the prognosis, crucial to decide a deep and continuous sedation maintained until death, appears to be very difficult and various, between hours and few weeks. Half of respondents were concerned that this practice could lead to or hide euthanasia practices, whereas for the other half, this new law formalised practices necessary for the quality of palliative care at the end-of-life.ConclusionMost respondents support the implementation of deep and continuous sedation maintained until death in routine end-of-life care. Nevertheless, difficulty to stop hydration, confusion with euthanasia practices, ethical debates it provokes and the risk of misunderstanding within teams and with families are significant. This is certainly shared by other teams. This could lead to a multi-centric survey and if confirmed might be reported to the legislator.
