[Contributions to the development of a public health information system. SESPAS Report 2010]

New public health laws are a conceptual and methodological adaptation of public health to current social needs, their common link being the incorporation of health in all policies. This represents a new strategic approach that will require different information systems, which should incorporate the rapid advances made in the field of information technology and communication. The aim of this article was to identify the most important aspects to be taken into account in information systems in public health from a technological perspective, both in their development and in the elements that compose them. To overcome the fragmentation of information systems in public health, these systems must be successfully integrated among themselves and with other health and non-health systems. To achieve this task, technical, semantic and organizational interoperability must be ensured. Emerging technologies should be considered to support these new strategies, especially Web 2.0 tools. This new strategic development will pose additional challenges because of its size and the diversity of the departments involved. It is proposed that information systems will include the elements of Web 2.0 and support systems for decision-making technologies in addition to the traditional operational systems.
