Let me state that my intention in including CoMeBeh in the article, to begin with, was to introduce it to people who might not know about it, as a more sensible approach to integrated care than the Katon model, which refers primary care patients to very limited psychiatric care. At least, I think it's more sensible. I've certainly treated patients who would have benefited immensely from such a program, and it's unfortunate that they didn't have access to it.
The following is closer to what I was trying to get at, and I will change the Let's Talk about the ACA post to include it:
Other models of integrated care exist, such as the Collaborative Medicine and Behavioral Health (CoMeBeh) project at the University of Iowa, in which primary care is provided by physicians rotating through the psychiatry clinic, rather than the other way around. This excellent model is, unfortunately, limited by the fact that it targets a smaller population than the Katon model—those patients already in psychiatric care.
