The challenge of delivering health care on a more cost-effective and equitable basis has led to the formation of new kinds of organizations, which in turn require new kinds of management information systems. The system described in this article is used for planning resource allocation and monitoring the overall performance of Livingston Community Health Services, Inc., a rural community-owned health service designed to provide comprehensive care to a geographically defined target population.The Health Services Data System processes information on performance and productivity, effectiveness with respect to the target population, and billing and financial activities. Input consists of the results of a community census and two household surveys, patient registrations and patient services operating data, and financial data. Besides billing patients automatically, the system integrates financial, demographic, and health services utilization data to generate monthly summaries for the administrators, medical director, and community board. The article discusses several examples of these summaries, stratifying utilization by geographic location of residence, age, income, and race.
