[Towards a multilevel psychiatric liaison]

The first of this pair of articles ends with the observation that -psychiatric liaison activity remains underdeveloped. Moreover, -psychiatric liaison is not based on sound empirical foundations and is not taught, which has had the consequence of putting it out of step with the transformations of medicine and the medical profession. In this second article, we discuss possible evolutions of psychiatric liaison and the role that social sciences can play in them. Both -articles are related to the creation of the first position of Professor in psychiatric liaison by the Faculty of Biology and Medicine of the University of Lausanne and the CHUV, a position held by a researcher from the social sciences.
