Abstract:	The growth of child and adolescent psychiatric services based on the wraparound philosophy raises new questions for medical directors, investigators, and clinicians interested in improving quality of care and outcomes. Typically, quality improvement studies have focused on standardizing care and decreasing variation while community based services following a wraparound model are by definition individualized. To date, little information on how to evaluate such services in a managed care environment has been available. We present one option for evaluating the distribution of medical services and the extent to which providers individualize services for children with severe emotional disorders. Specifically, we (a) review the philosophy and goals of wraparound services, (b) introduce the Lorenz curve as a tool for determining the degree of inequality in service distribution at a given institution, and (c) present a case study on the use of Lorenz curves by a Medicaid Behavioral Health Organization in profiling behavioral providers.
