La simulation managériale en santé comme dispositif sociopédagogique de construction collective de savoirs professionnels.: Emergence d’un modèle de construction collective de savoirs professionnels au CHU de Lille.

This article offers a sociological analysis of an innovative simulation-based training programme implemented since 2022 at the Lille University Hospital, aimed at healthcare managers, within which the author conducted participant observation as an expert practitioner. Drawing on contributions from the sociology of collective action, socioconstructivism, Goffmanian interactionism, distributed cognition theory, and the sociology of professions, we demonstrate that managerial simulation in healthcare cannot be reduced to a pedagogical tool: it constitutes a sociopedagogical device in the fullest sense — a space for the objectification of practices, the redefinition of professional identities, the collective construction of situated managerial norms, and the production of a shared professional culture. Within this device, the sociologist participates in the emergence of collective expertise, adopting a stance close to Alain Touraine's sociological intervention, while distinguishing himself from it.The analysis draws on twelve training sessions (160 participants between 2022 to 2025) and on the results of a dual qualitative and quantitative evaluation. We show that the protocol, structured in five stages, produces cognitive, emotional, and identity-related effects that extend well beyond the initial pedagogical objectives. The systematic integration of the sociological dimension constitutes a differentiating factor that contextualises managerial practices in relation to social expectations and their structural determinants, and opens a space of critical reflexivity from which collective initiatives emerge. The discussion examines the normative assumptions underlying the device, its methodological limitations, and the conditions for its broader application, while setting out the foundations of a research agenda in the sociology of managerial simulation in healthcare.
