To remedy lacks in modeling and analysis of health care flow, we present in this paper a new modeling methodology for addressing organization problems of health care systems. It is a patient-centered meta-model based on three views : (i) process (pathway of patients), (ii) resource (activity of involved resources), and (iii) organization (resources relations and specializations, structure of the system). These personalized view are a powerful communication tool. The resulting meta-model can be instantiated for a specific system and immediately simulated via templates, offering a fast-prototyping tool for health care systems.
