In my experience, in a majority of cases, patients who had received palliative care and wanted to receive medical assistance in dying received both. It was a decision that came after consideration.
A patient who is in the terminal phase, for example, can be admitted to palliative care and receive care as their condition changes. Often, these people are already considering medical assistance in dying. We then discuss that possibility together, at the same time as they are receiving the usual palliative care. Sometimes, these people change their mind, but in a large majority of cases they do not change their mind. The large majority of people who maintain the wish to receive medical assistance in dying do receive that care, even if they are simultaneously receiving palliative care.
