For the first time in history, behavioral health providers are expected to understand and participate in activities intended to access and improve the quality of services they provide. This handbook is designed as a general resource in the field of behavioral health quality management for a very diverse group of readers, including graduate and undergraduate students, payors, purchasers and administrators within managed care organizations, public sector service system planners and managers, applied health services researchers and program evaluators. This volume provides a comprehensive context for the development of quality management (QM) in health services - behavioral health in particular - as well as an overview of tools, techniques, and programs reflecting QM in practice. It also offers perspectives on both internally- and externally-based QM activities.
