This report focuses on technical issues associated with informatics--a term covering all aspects of the development and operations of information systems, the supporting computer methodology and technology, and the supporting telecommunications links. The first of six chapters discusses the purpose of the report together with basic assumptions about health care systems as related to informatics and the use of computer-based information processing and transfer in telecommunications; key computer applications in health; and current trends in these rapidly evolving technologies as they apply to health. Subsequent chapters deal with national health informatics policy and strategy; informatics support for health programs and in the provision of health care; informatics for health manpower development; and the choice of informatics technology. It is concluded that informatics will be increasingly used in all organizations and that its use must be managed. Three annexes contain a list of participants in the international consultation on application of informatics; brief descriptions of sample curricula; and an eight-page glossary. (CGD)
