Continuous Palliative Sedation for Existential Distress? A Survey of Canadian Palliative Care Physicians' Views.

BACKGROUND Palliative sedation can be used for refractory symptoms during end-of-life care. However, continuous palliative sedation (CPS) for existential distress remains controversial due to difficulty determining when this distress is refractory. OBJECTIVES The aim was to determine the opinions and practices of Canadian palliative care physicians regarding CPS for existential distress. METHODS A survey focusing on experience and views regarding CPS for existential distress was sent to 322 members of the Canadian Society of Palliative Care Physicians. RESULTS Eighty-one surveys returned (accessible target, 314), resulting in a response rate of 26%. One third (31%) of the respondents reported providing CPS for existential distress. On a 5-point Likert-type scale, 40% of participants disagreed, while 43% agreed that CPS could be used for existential distress alone. CONCLUSION Differing opinions exist regarding this complex and potentially controversial issue, necessitating the education of health-care professionals and increased awareness within the general public.
