How should health care providers inform about palliative sedation? A qualitative study with palliative care professionals.

In Switzerland, palliative sedation consists of using sedatives to relieve terminally ill patients. It is divided into several steps, with one of them consisting of informing patients and relatives about the procedure. In the current recommendations, there is a lack of orientation about how and when this discussion should take place. Hence, we aim to explore perceptions and experiences of palliative care professionals regarding these questions. Qualitative semi-structured interviews with five physicians and five nurses working in specialised palliative care were conducted. They were then analysed with thematic analysis. Results showed a uniformity around definition, goals and indications of palliative sedation. However, there was a lack of consistency regarding the process of delivering this information to patients and relatives. Finally, some participants strongly opposed the idea of systematically informing patients in specialised palliative care, while others were more divided on this question. Despite a common understanding of the concept of palliative sedation, there is no standard practice when informing patients on palliative sedation among palliative care professionals. Therefore, this study demonstrates the need for further guidelines on this question and calls for a better understanding and knowledge of palliative sedation among health professionals outside palliative care.
