In this paper we aim to provide information on the importance of efficiency measurement of health care facilities in developing countries. We state that efficiency measurement can be a substantial contribution to saving lives. Therefore we analyse the performance of health centres in rural Burkina Faso making use of data which were taken from a comprehensive long-term cost information system. In the subsequent parts of this article, the study site is described and the DEA method outlined. The ensuing analysis of the data is carried out in two stages. Firstly, quantitative aspects concerning relative efficiency are presented. Secondly, the measures of performance are explained. The implications of the results are then discussed.
