[Knowledge translation: the basics for public health professionals].

Knowledge translation (KT) in Public Health involves the use of scientific evidence by decision makers when generating health policies directed to accelerate the benefits resulting from research and innovation in health system and ultimately people´s health. In this paper we review the definitions and conceptual frameworks related to systematization of KT processes. The different approaches to KT share the concept that KT is composed by two main elements: a product (information) developed through scientific method with a friendly format for the target public and an action devoted to support or promote a health related practice using the aforementioned product.
