Effectiveness and efficiency of integrated mental health care programmes in Germany: study protocol of an observational controlled trial.

Background: Since 2009 some German health insurance companies have implemented integrated mental health care services along the principles of assertive community treatment in collaboration with local mental health service providers across Germany. Focus of this study is the analysis of effectiveness and cost-effectiveness of this integrated care programme compared to care as usual in routine care surroundings in five regions in Germany.

Methods: In this 18-month multi-centre observational trial 250 patients enrolled in an integrated mental health care programme and 250 patients who receive treatment as usual from five catchment areas will be included.
