Priority for primary health care: its development and problems

National health policies of many countries stress priority for primary health care (PHC). This emphasis has arisen as a reaction to large expenditures on hospitals and sophisticated technology in major cities of developing countries, while vast rural populations have been virtually ignored. The paradox developed from colonial and neo-colonial emulation of European and North American medical models. In 1978, an international conference of WHO/UNICEF at Alma-Ata, USSR defined the meaning of PHC, along with several principles of organization and equity under which it should be provided. To reach rural people with PHC, thousands of community health workers have been prepared and stationed in villages. Their training, however, is very brief and, with weak supervision, their performance has been disappointing. To achieve the WHO goal of "Health for All" through PHC requires greatly expanded education of public health leaders, who can supervise and inspire community personnel.
