Traditional approaches in healthcare have been challenged giving way to broader forms of users’ participation in treatment. In this article we present the Health 2.0 movement as an example of relational and participatory practices in healthcare. Health 2.0 is an approach in which participation is the major aim, aspiring to reshape the system into more collaborative and less hierarchical relationships. We offer two illustrations in order to discuss how Health 2.0 is related and can contribute to a positive uptake of patient’s knowledge, which implies challenging healthcare practices exclusively focused on scientific expertise. In contrast, the illustrations we discuss focus on relations and cultural practices, searching for responsive and context-sensitive interventions, entertaining multiple views and allowing space for creativity. Finally we introduce two relational resources to contribute with the development and sustainability of Health 2.0 practices: Relational being and edge of fluidity. Those are resources aiming to engage professionals in a type of conversation with their clients, which is different from the hierarchical, linear and fact-oriented approach. This conversation aims at creating a space where the voices of all involved are welcomed, raising different opinions and points of view, bringing up new light and possibilities to the problem being investigated. These resources may be useful for those who are interested in improving quality in healthcare by investing in collaboration, contextual sensitivity and relational engagement.
