This publication provides physicians, scientists, and members of industry and government with a comprehensive overview of the role and impact of medical standards and measurements on health care. The insights, discussions, and recommendations presented in this text are representative of many individuals' contributions. However, coordination of this endeavor is due to joint participation by three primary organizations: the National Bureau of Standards, the American Medical Association, and ASTM. One central theme of this book addresses the need to integrate the physician's views with business and standards development organizations.
