[Psychiatric liaison: From yesterday to tomorrow].

This article reviews the genesis and development of liaison psychiatry, whose mission is (i) taking care for patients with psychiatric comorbidities (psychiatric consultation) and (ii) transferring knowledge and skills to somatic medicine and supporting clinicians in their practice (psychiatric liaison). We argue for a strengthening of psychiatric liaison and a consistent focus on the clinician as an object-subject of research, of training and of support. The following article will discuss the contribution of social sciences and quali-tative research to medicine and psychiatric liaison and outline the contours of a clinician-centered liaison model.
