While interprofessionality is indispensable to respond to home care current issues, its implementation in the practice is a real challenge. The Genevan domiciliary model (reference by a nurse, targeted areas of interventions, etc.) needs to integrate all the resources of proximity. For this purpose, an interprofessional ambulatory and of proximity care network (RIAP) was created, aiming at strengthening the exchanges physicians/nurses about shared patients. RIAP benefits from an encouraging first assessment. Learnings from this experience are used to refine the modeling of this type of proximity network.
