actually diabetes psychiatry is a slow but growing field!
And if a psychiatrist decides to insert himself/herself into making future predictions with no real science behind it, that doctor is practicing quackery.
If an IM or endocrinologist asked me to give advice on a patient future compliance to insulin, I read over his history and gave advice, it'd be based simply on my own common sense. In several studies where psychiatrists have been asked to do things outside their field such as determine if someone is lying, they did not do better than a layman.
If psychiatrists want to play this faux role, they are not practicing psychiatry. If they want to actually research, learn, and understand the science of predicting future behavior and do consults asking them to predict the future, so be it because they actually then are using evidenced-based methods but they are not practicing psychiatry as it is currently defined. That is said with full deference that someone needs to do this and that would be something beneficial.
I don't see much difference between a psychiatrist trying to make predictions without any science to back him up and Madame Cleo. I suspect if their insurance carrier mandates they not practice outside their field, they'd be in violation of that, and thus not covered by insurance, and in many states to practice under those conditions is illegal.
Regarding diabetes, there actually is some psychiatric issues in that area, especially with mental state. Low blood sugar, for example, causes irritability. But that is a far cry from predicting future behavior.
Transplantation psychiatry is far more than tea-leaf reading and trying to guess what will happen. That is a very small part of the assessment. There are lots of weird and wonderful neuropsychiatric complications due to immonosuppression, issues with coping, grief, abnormal illness behavior, living donors, adjustment disorders, mood disorder, personality pathology, capacity, family systems problems, health behavior change etc.
Somewhat agree, and I have read evidenced-based papers on transplant psychiatry, but all the above minus the psychiatric disorders is stuff any doctor can handle and they do not necessarily need a psychiatrist for that. If someone has a personality pathology, or psychosis as a result of corticosteroids, yes we can provide assistance, but in dealing with families, any doctor should be able to handle that. If transplant doctors don't want to deal with it, my argument is that instead of expanding our field to do something outside our parameters, why not expand their role to do something they're supposed to do anyway.
When this has happened in the forensic psychiatric arena, the APA argued we shouldn't be doing things such as predicting future violence, and then the Supreme Court ruled something to the effect of -too bad, someone needs to do it, we can't think of anyone else so you're stuck with it.- At least in that situation there now is a legal mandate to perform outside our specialty even if we don't want to do it. Since then there have been evidenced-based advances, but for years psychiatrists were operating on no science when doing this type of stuff but they were forced by the court to do so.
