Clinical treatment matching models for dually diagnosed patients.

The models of serial, parallel, and integrated treatment should help administrators and clinicians to think through resources they have and ones they may be able to share. Certain patients should do better with one or another of the models, but these empirical approaches need testing. Though large controlled outcome studies for various models of dual diagnosis treatment are pending, pilot studies of interventions have been positive, and the need for designing and implementing sensible programs to address the dual diagnosis patient is here right now.
