Combining traditional healing and contemporary medicine requires several steps. The western health professional cannot easily interact with the traditional healers. Intermediate steps are essential: the persons steeped in western medicine and culture must transmit their knowledge to educated health personnel from the indigenous society, who then interpret knowledge and skills and convey them to the indigenous healers. The paper describes the first of a series of training-of-trainers' workshops held for 20 experienced midwives and auxiliary midwives working in the organized health system in rural areas of Zaire. After returning to their posts, these persons train the rural traditional birth attendants (TBAs). The workshop instructed the midwives to identify customs and practices of TBAs; how to teach them about maternity care and family planning; and how to evaluate and supervise them in their communities.
