With regard to the latter part of the statement, about whether it is common practice, yes, I would say it's common practice in many areas. The primary care physician, the family physician, does play a key role in mental health provision.
However, in evaluating the thought processes that are going into a request like PAD, if there's a mental illness present, it's essential that people who have the required training be the ones who make that assessment.
I'll give you an example. I mentioned to your colleague that in the month prior to completed suicides, about one in five people have seen a mental health provider. In the same month, nearly half—about 45%, typically—have seen their primary care physician.
That's not to suggest that the primary care physician is not able to look at mental health needs. They can, but when we're doing complex risk assessments and complex assessments of what's behind someone's wish to die, we do need to bring in psychiatrists at that point.
