Health status of populations as a measure of health system performance.

This article describes the assessment of self-reported health status as one indicator of the performance of health care delivery systems. This work took place in the context of a larger effort to measure performance in health care. The Consortium Research on Indicators of System Performance (CRISP) project is developing measures of the performance of integrated health care systems, rather than plans or providers. The system focus leads to measurement of the health status of defined populations and an analysis of health care episodes and processes extending beyond the physician's office or hospital that relate directly to patient outcomes and satisfaction. This focus provides opportunities for application of performance measures to quality improvement efforts, since outcomes can be logically linked to identifiable and measurable processes. After a discussion of the purpose and the history of CRISP and how populations were defined within the systems, some preliminary data on the health status of populations are presented.
