Abstract
BACKGROUND: Patients approaching end of life may experience intractable symptoms managed with palliative sedation. The legalization of Medical Assistance in Dying (MAiD) in Canada in 2016 offers a new option for relief of intolerable suffering, and there is limited evidence examining how the use of palliative sedation has evolved with the introduction of MAiD. OBJECTIVES: To compare rates of palliative sedation at a tertiary care hospital before and after the legalization of MAiD. METHODS: This study is a retrospective chart analysis of all deaths of patients followed by the palliative care consult team in acute care, or admitted to the palliative care unit. We compared the use of palliative sedation during 1-year periods before and after the legalization of MAiD, and screened charts for MAiD requests during the second time period. RESULTS: 4.7% (n = 25) of patients who died in the palliative care unit pre-legalization of MAiD received palliative sedation compared to 14.6% (n = 82) post-MAiD, with no change in acute care. Post-MAiD, 4.1% of deaths were medically-assisted deaths in the palliative care unit (n = 23) and acute care (n = 14). For patients who requested MAiD but instead received palliative sedation, the primary reason was loss of decisional capacity to consent for MAiD. CONCLUSION: We believe that the mainstream presence of MAiD has resulted in an increased recognition of MAiD and palliative sedation as distinct entities, and rates of palliative sedation increased post-MAiD due to greater awareness about patient choice and increased comfort with end-of-life options.
