By the rural area health care special law in 1980, Primary health care posts were established in rural areas as fundamental elements of the national health system. Nurses have been deployed to the posts after taking an education course mandated by the special law. However, health care posts have confronted environmental changes over the past 30 years such as an aging and decreasing rural population and advanced traffic systems, which make it necessary to reshape their form and role. Therefore, some guidelines are suggested for future role enlargement of health care posts by analyzing their current management and duties. The guidelines are as follows: 1) enlarging the portion of prevention and management of chronic degenerative diseases, 2) development and practice of diverse health promotion programs, 3) extension of primary health care for the increasing older population, 4) development of health programs for married immigrants, 5) practice of timely maternal child health programs, 6) development of adequate health care posts for low-income people in rapidly urbanizing rural areas and in poor areas in big cities, and 7) revision of laws and institutional arrangements for the role enlargement of health care posts to match social changes and customer needs.
