Knowledge dialogues, also called intercultural dialogues, are processes of communication and exchange between people, groups or communities that come from different backgrounds or cultures. In the case of the health sector, exchanges take place between certain groups or individuals and trained health personnel. Its objective is, among others, to improve access to health services and build intercultural health, with emphasis on solving previously raised problems and their causes, mutual understanding and the creation of solid links. This publication, which contains the methodology applicable to this field, is aimed at health personnel or other areas and sectors in order to contribute to the search for ways to know, share and build healthy practices. The groups considered in this case are the indigenous and Roma populations, and the Afro-descendants, although strictly speaking the methodology can be applied to working with any group (migrants, displaced persons, adolescents, the elderly, etc.) that presents problems of universal access to health and universal health coverage.
