Estimating the Investment Gap in Treating Serious Mental Illness in the United States.

Abstract

Despite substantial enrollment of adults with serious mental illness in state Medicaid programs, public-sector funding remains inadequate to deliver comprehensive evidence-based mental health care. The authors of this Open Forum propose a rigorous empirical method for quantifying the investment gap between current resources and those required for achieving evidence-based care. Drawing from an analysis of California's county-based mental health system, the authors outline a four-step process that entails quantifying current mental health service utilization, defining evidence-based clinical standards, estimating unit costs, and scaling services to population needs. This approach should provide states with actionable economic insights to guide strategic investments and clinical outcomes.
