Chapter 17 DOI: 10.4018/978-1-5225-2394-9.ch017 ABSTRACT There is a growing literature on health and health care dedicated to empowerment of patients; but there is still a gap in the literature to conceptualize knowledge, to extend the discussion of the empowerment of the patients to the stakeholders. The discussion is at the level of managerial processes of empowerment and knowledge management related to health care. The present chapter starts with a review on empow- erment, especially focused on the health sector. The following sections will develop a critical analysis of empowerment, mainly around the concept of tacit knowledge (Polanyi) and knowledge management. One key variable is the proximity of the actors involved in the empowerment process. This key variable is very much related to the tacitness issue of knowledge production and fows. The chapter extends the discussion of the empowerment of the patients to that of the stakeholders and the general debate about health literacy. A model is briefy described for the purpose of illustrating the learning process in a knowledge management implemented in health care.
