This textbook presents a conceptual and methodological framework for implementing quality assurance programs in mental health services, with specific emphasis on peer and utilization review. Both the content of the review and the methods of accomplishing it are addressed. The early chapters of the book are designed to show the many types and styles of evaluation criteria available, and to help readers determine what is appropriate for their facility. Mechanisms for measuring the quality of care and the process of concurrent and retrospective review are described. Different criteria formats and modes of criteria development are outlined, with specific attention paid to the concurrent review of partial hospitalization and ambulatory services. The implementation of a quality assurance program is then discussed. The quality assurance cycle is described and educational and organizational interventions are outlined. The focus of the book then shifts to the nature of organizations, to quality assurance activities within the framework of organizations with varying structures, and to the establishment of a functioning utilization and peer review system. Numerous figures supplementing the text, an annotated bibliography, an author index, and a subject index are included. (JAC)
