The Regional Coordination VHL is exercised by BIREME and includes the activities of promotion and dissemination of the VHL model, exchange between VHL producers, intermediaries and users, regional coordination of the network of institutions etc. In the national scenario, the national instances assume the responsibility of coordinating the national network of institutions, as an essential way to promote and ensure the visibility and accessibility on information and knowledge in health in the region. The coordination of the VHL in the countries is held by one or more institutions, in accordance to the same orientations and principles of the work developed by BIREME in the regional scenario. The coordination of each instance, on the other hand, is held by a dynamic set of institutions, that articulates every action towards the VHL development. A more detailed approach to the VHL management is available in the VHL Guide and in the set of documents contained in this section.
