ISO/TS 21667:2004 establishes a common health indicators conceptual framework for the field of health informatics. It is intended to foster a common vocabulary and conceptual definitions for a framework which defines the appropriate dimensions and subdimensions required to describe the health of the population and performance of a health care system, which is sufficiently broad (high-level) to accommodate a variety of health care systems, and which is comprehensive, encapsulating all of the factors that are related to health outcomes and health system performance and utilization, and regional and national variations. ISO/TS 21667:2004 does not identify or describe individual indicators or specific data elements for the health indicators conceptual framework. The definition of benchmarks and/or approaches used in the definition of benchmarks is outside its scope.
