Even if a person solemnly designated a third party at a meeting held for that purpose and specified when he or she wanted medical assistance in dying to be administered, the fact remains that the process is spread over time and must therefore include a reassessment measure, as you mentioned. Meetings must be planned throughout the patient's journey to reassess the situation until the designated third party ultimately asks the attending team to assess the loved one's condition. There have to be repeated assessments.
In your experience, how many of these kinds of stages must there be? Is this done on a case-by-case basis?
