New management styles imposed on hospital institutions in recent years have fundamentally changed the way they are organized. Many texts discuss the consequences that these new management styles have, especially on the field of communication. The aim of this study was to understand the true impact that these new management methods have on communication by managers in hospital, but also on care teams in terms of satisfaction and/or stress. This two-year study was conducted among 900 executives in hospitals in Western Switzerland using a mixed methodology. A first phase of questionnaires highlighted the problematic areas, while a second phase in the form of organized group interviews in each hospital aimed to achieve a better understanding of the relationship between management and communication. The latter proved to be particularly significant in terms of results, and this is the one we focused on in this article. These results indeed show that a crucial role is given to communication by carers, and, at the same time less time is devoted to relationships, both among peers and with patients. Frustration then arises, which is not without consequences both for the management of patients and the institutions themselves. It is by means of these results that awareness is raised of the omnipresence of communication at all levels and the major advantages that a positive dynamic has. On the contrary, awareness is raised of the serious problems that may arise from management practices that do not give due importance to the dimension of communication, present in all sectors of the hospital.
