Spending on antipsychotic medications continues to escalate as new products such as atypicals are increasingly used to treat schizophrenia and other conditions. Given that per person spending on behavioral health benefits is shrinking while spending on pharmaceutical products is increasing, the psychotropic portion of mental health expenditures is likely to continue to increase in the future. The diffusion of these new behavioral health technologies, or the rate at which these products have spread through the market, has been very uneven. Differences in adoption and diffusion rates of psychotropic medications across insurance settings, geographic regions, or subpopulations defined by age, gender, or racial or ethnic groups have important implications for the quality of care received by persons with mental illnesses. This article reviews the evidence on the diffusion of antipsychotic medication and discusses the implications of formulary policies on diffusion, addressing the health care service and administrative context in which the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) project is being conducted and which it is intended to inform.
