I think we have to remember that it's the whole package, to put it into context. By removing that, it doesn't mean that you throw everything else out. There are other criteria that a person does still need to go through, and that I, as a practitioner, need to think about. I'm also going to be in a therapeutic relationship with this person and will have thought about coercion and about all those other items that you brought up. That's part of the safeguard and part of being able to counsel and enter into it.
However, whether you're 18 or not, I think you have to ask yourself: does the person have a grievous and irremediable medical condition, and are they suffering?
At the end of the day, I would promote patient-directed care, so I'm going to take it up a little bit more than patient-centred care and move into the patient-directed care. If we focus on that, then can someone who is a mature minor direct their own care?
