I am aware of what you mentioned. Like I said, if you are doing evidenced-based work there's nothing wrong with it.
Yet there are psychiatrists who are asked in the name of "transplant psychiatry" to do things outside of what you mentioned. E.g., as I mentioned, a psychiatrist trained like almost any other, they know their antipsychotics, antidepressants, etc, but they never once used a structured tool in their assessment nor were ever trained on ever using one. Their training did not include 1 lecture on transplant psychiatry. Then they are asked "will the patient be compliant" and the doctor foolishly answers so on a consult.
Also the 2nd paragraph you mentioned, the APA asked that we not "predict the future" but what happened was the SCOTUS basically in a landmark decision nicely told the APA something to the effect of screw you, we don't care. We're going to make you do it whether you like it or not even if the science doesn't back you up. So psychiatry took it up despite that it argued it wasn't within our skill-set.
So since then some psychiatrists and psychologists took up the challenge and started adding tools as you mentioned with a full declaration that what the SCOTUS did was highly questionable at best, but in that regard (and that one only) we've been forced into the bad position and we have to push the science further. The science still leaves a lot of of grey area but it is better than clinical judgment alone.
But even along what you mentioned, actually several forensic psychiatrists aren't schooled into those assessment tools. Several, even forensic psych fellowships, aren't teaching their students about the use of assessment tools or aren't expecting them to use them. Several PDs I've seen don't know how to use an assessment tool, even expressed anger you even brought it up. Further some psychiatrists, especially in areas that do not use the Daubert expert-testimony standard courts are still using psychiatrists that make claims based on no science but based on "I'm a psychiatrist so I'm right" despite that there's no real hard evidence to back their claims.
To piggy-back on splik's post, if thats what's being asked of the psychiatrist, then there's a systemic problem with the program. In my experience, the decision has already been made by the clinical team, but they're struggling to articulate their reasoning -- i.e. they know intuitively this is a high risk candidate based on having done thousands of procedures, but may need help putting it into words and determining if the problems are reversible. The training, tools and instruments help organize that - to what extent is it untreated depression, personality disorder, cognitive impairment, poor social support, past episodes of being burnt by the patient, etc. but its not like they're ready to put a patient on the transplant list then hit the brakes when they find out they scored high on the TERS or SIPAT (which have fairly subjective components, anyway). If you can do a thorough psychosocial assessment, treat basic depression/anxiety, counsel problematic relationships, uncover MCI, etc., all things learned in general training, you can add something without calling yourself a "transplant psychiatrist."
If you're really into it, you can add value as an MD by providing another source of medical information, either to reinforce what the patient may have missed at previous appointments, or answer questions they were unable to ask, which is not something psychologists would feel comfortable with.
Of course, that doesn't mean there aren't inappropriate consults but, again, not a reflection on the field of psychiatry. There are plenty of consulting services who want a rubber stamp or just to be told what they want to hear, and many don't have the interest or capability to seek out the appropriate specialists. Then there are psychiatrists who give up on trying to explain for the millionth time whats a reasonable consult question, or just want to collect a paycheck, or just want to be a team player/get the respect of the jocks, and go along with it. And I imagine its ten times worse in the forensic world with lawyers willing to pay exorbitant amounts to get the "expert" testimony that they need for their case, and doctors happy to sellout (I'd add thats not just a problem with psychiatry but all of forensic medicine/dentistry/science --
see exhibit A).
If your point is people have unrealistic expectations of psychiatry, sure. Its the flip-side of "I'm afraid to go into psychiatry because I'll stop being a real doctor" post. In both cases, I think the answer is to have enough self-confidence in what we do well, not ceding more turf but being aware of our limitations.
