Section 1, Components of the Continuum, covers a range of services from office-based to acute inpatient treatment. Section 2 consists of five chapters, each focused on an at-risk population, including children and the elderly. Section 3 contains six chapters highlighting planning, administrative, educational, and research issues. This most helpful section may well become "must" reading for psychiatrists in administrative positions. It is also a useful entrée into one of the most progressive elements in the evolution of health care, which is conceptually separate from the coincidental advent of managed health care: the emergence of evidence-based medicine to support clinical decision making under conditions of uncertainty. As others have emphasized, the emergence of evidence-based medicine may be the most beneficial and lasting of the current changes, irrespective of the eventual organizational structure of the health care economy.
