[The impact of research in clinical practice].

This work analyzes the way in which scientific knowledge can modify clinical practice and generate changes in the behavior of professionals, incorporating the new discoveries to their common practice. The main phases of the research process are three: knowledge production, transmission and application. Analyzing each of them will allow us to evaluate the overall impact of research in clinical practice. There is a great amount of information related to the way in which new knowledge should reach health care providers. The challenge is to reduce the gap between clinical practice and the generation of new knowledge based on improved evidence.
