Use of palliative sedation following Medical Assistance in Dying (MAiD) legislation: A mixed-methods study of palliative care providers.

Abstract

Palliative sedation (PS) and Medical Assistance in Dying (MAiD) are options for end-of-life (EOL) care in Canada, since the latter was legalized in 2016. Little research to date has explored the potential impact of MAiD on PS practices. This study investigated physicians' perceptions of their practices surrounding PS and how they may have changed since 2016. A survey (n=37) and semi-structured interviews (n=23) were conducted with palliative care providers throughout Ontario. Questions focused on PS practices and explored potential changes following the implementation of MAiD. Codes were determined collaboratively and applied line-by-line by 2 independent investigators. Survey responses were analyzed alongside interview transcripts and noted to be concordant. Themes were generated via reflexive thematic analysis. Thematic analysis yielded the following themes: (1) Increased patient/family knowledge of EOL care; (2) More frequent/fulsome discussions; (3) Normalization/repositioning of PS; and (4) Conflation and differentiation of PS/MAiD. Across these themes, participants espoused increased patient, family, and provider comfort with PS, which may stem equally from the advent of MAiD and the growth of palliative care in general. Participants also emphasized that, following MAiD, PS is viewed as a less radical intervention. This is the first study to investigate physicians' perspectives on the impact of MAiD on PS. Participants strongly opposed treating MAiD and PS as direct equivalents, given the differences in intent and eligibility. Participants stressed that MAiD requests/inquiries should prompt individualized assessments exploring all avenues of symptom management - the results of which may or may not include PS.
