The French emergency medicine infrastructure (structures de médecine d'urgence) ensures patients care from the very location of the distress to the appropriate hospital department: medical care in the field, by hospital clinical teams (the services mobiles d'urgence et de réanimation [SMUR]), is a key characteristic of our medical emergency response system. Response to medical distress revolves around information about not only the location and characteristics of the medical need, but also the availability of adapted hospital services. Gathering and transmitting this information is the prerogative of the service d'aide médicale d'urgence (SAMU) and its telephone dispatch center (Centre 15). For patients coming directly to the hospital, the emergency room (ER), a former underfunded and neglected hospital service, has become a key point of access. The ER is now responsible, after providing immediate first line care, to guide the patient through the care system. As such they are equipped with short term hospitalization units designed to enable up to 24h patient observation before orientation. This ensemble, networked at the level of a health territory, ensures the quality, safety, and efficacy that the population is entitled to demand.
