[The challenge of Web 2.0-based >].

: Intensive medicine has the opportunity to create an interactive virtual community using Web 2.0. The main feature of this new web generation is to convert the user into an active element of the virtual world, allowing the passive, information-searching user to become one who creates, shares, participates and closely relates to it. These features make it possible for the clinical sphere, the researcher and the innovator to coincide, thus providing interaction not only among the members of the virtual community but also with citizens and patients. The creation of a Web 2.0-based > represents an opportunity for improvement as well as an added value for intensive medicine.
