Résumé
ERIOS, is a collaborative project between Dedalus, a health software company, Montpellier University Hospital Center (CHU), and the University of Montpellier. This initiative aims to incorporate research and development (R&D) directly within th e hospital, focusing on co-creating components of the Electronic Health Record (EHR) alongside end-users. The project was initiated with two initial use cases, which led to the development of components for dynamic temporal visualization, now integrated into specific dashboards. The application of academic recommendations regarding user engagement methodology and human-computer interactions significantly enhanced our ability to meet user needs.
