Yes, you're right. The answer is in your question.
What we have learned in Canada over a period of six years now, and slightly longer in Quebec, is that we never encountered the slippery slope against which everyone was warning us. A doctor assesses a patient and a second doctor or a clinical nurse does an assessment to determine whether the patient's circumstances meet the criteria. To my knowledge, and according to what is reported to us by Quebec's commission on end-of-life care and coroners elsewhere in Canada, there have been no problems of this kind.
In Quebec, there are confidential discussion groups made up of doctors. In Canada, there is the CAMAP, where disputed cases are discussed. Some prefer not to go in that direction. There is discussion, but it is about a clinical plan.
I will conclude by saying that decisions like these are made every day in neurosurgery and cardiac surgery. The administration of all these aggressive treatments—and I am using the word correctly—of our patients is a decision made in accordance with our collegial procedure.
