I know one of my docs was a whistle blower, and had the usual hideous time over it. So yes, some do...the college of psych. Probably has some input. MH people are notoriously vulnerable and a long term " problem". I personally believe, that advocacy needs to come from the consumer and peer group supports like here for example.
When I was first admitted into the state health system, honestly a rabid dog or a prisoner would have had better care. It was repellant and demeaning.i hope this has changed, but I would not like to check it out. There are outside people who act as some sort of advocate when you are sectioned, I dimly recall...but i cannot really speak on that as those years were really fuzzy. I just went into my head and stayed there!
