Primary health care is not cheap: a case study from Guinea Bissau.

In 1977 the Ministry of Health in Guinea Bissau started two regional community health projects. In this article we describe the progress of the Tombali project. Three aspects are discussed: the "Learning Process Approach" used in the project; measurement of the effectiveness of the project and the problems of collecting and interpreting these data; and the ratio of investment to recurrent costs and the proportions borne by government and by villagers. Primary health care projects evolve slowly, and the importance of the willingness of project workers, donor agencies, and the national government to work without a blueprint plan is emphasized. We discuss ways of evaluating the success of primary health care schemes; the measurement of any change in health status is difficult and discounts other benefits that may result, such as encouraging community participation and involving villagers in government activities. Both government and villagers contribute significantly to the scheme, the government and donors bearing most of the investment costs, while most of the recurrent costs fall on the villagers. The data show that for neither government nor villagers is the scheme a cheap option to secure health care for rural populations. Finally, we discuss the lessons to be learned by national governments, donor agencies, and health workers from this attempt to implement a primary health care program.
