Again, speaking for the Canadian Psychiatric Association, we're founded on following evidence-based practice. We look at clinical practice guidelines.
If I think about clinical practice guidelines, the concept of a heroic measure is probably not well articulated there. I believe practitioners go above and beyond for patients and really think about what might be helpful for them. Despite that, there are people, as you've heard, that have outcomes that do not respond to a full complement of evidence-based interventions in addition to maybe some other unique innovative interventions.
