Not so much a vacuum as an appreciation for the fact that not all things related to patient care can be operationalized.
While psychologists will scoff at this statement, I stand by it.
Either you believe that the extra years of medical training will have some positive impact on psychiatric patient care, or you will not. Rare side effects and medical conditions are by definition, rare.
It just seems to me that the psychology camp is spouting ridiculous, equally unscientific 'data' (10 million prescriptions written without one bad side effect!). This doesn't even make statistical sense. Number needed to treat, time in treatment, medications and dosings used, psychologists being supervised by physicians, economic feasibility, medication class used, length of stay, discovery of serious medical conditions, management of adverse effect, and myriad other conditions are all part of a patient whole. To artificially pick one or two of these variables and measure it is not a real-world, useable or useful result.
Psychologists are very good at what they do. But in large part, I don't need what they want to tell me as far as managing my patient. Psychologists get on psychiatrists for not obsessing over the correct diagnoses, for example. While diagnosis is important from an academic standpoint, we are trained in medicine to treat symptoms. If you don't fully meet criteria for a particular DSM disorder but have a significant symptom(s) that's causing a problem - we treat it. As the picture changes, we treat the changing picture.
As a side note, I rarely go to the psychology forum, as it really has little to no information pertinent to me, but when I do, I see that it's filled with erroneous info and misinformation about psychiatrists. For example, the reason psychiatrists are "so excited about genetics" as posted in the psychology thread, is because we're soon going to be ordering genetic testing via dna analysis that will enable to tailor specific protein couplers and gene modifiers in the form of medication to most effectively treat psychiatric illnesses. We're not just running around 'excited about genetics' because we have nothing better to do or saw a special on the Discovery Channel.
