I've been in a situation where my therapist was a social worker, but he made his recommendations to the psychiatrist. The psychiatrist barely talked to me directly, he just had me fill out some tests about how I was feeling, and compared those results to the recommendations by the social worker.

And then prescribed me whatever the hell concoction made sense to him at the time.

Also, this anon is probably not worried about getting the details right about his friend's treatments. He probably didn't use the right word here.
