Of particular value to the reader is the choice of topics. Some chapters review areas that have been widely discussed, including effect on clinical practice, law, physical health, public sector, and training. Others deal with topics that have received less attention and are less well understood by many, including clinical risk management, quality management, employers' perspective, and employee assistance programs. A particularly interesting chapter reviews the literature on the impact of managed behavioral health care on spending, quality, and access; how savings are achieved; and the not-well-recognized, confounding economic variables that make it difficult to draw firm conclusions. A third set of chapters on information systems and services research address areas that have yet to achieve their potential for using managed care's vast reach and massive database to contribute to efficient, effective, evidence-based clinical and administrative services.
