As the potential of mobile systems is increasing especially in healthcare, a diagnosis is made of the information system of INEM (National Institute for Medical Emergency) in terms of some of its weaknesses and changes. In the case of human lives, which require speed and quality of care in a specific context and location, it is essential that healthcare institutions implement mobile and context-aware systems in order to prevent gaps in care from the time of first contact with the patient. This paper presents a system’s architecture, provided by the technical and functional development department of a company (Algardata) for context-oriented systems in dynamic environments. The aim is, whenever the patient changes his location, to immediately discover the services that best fit his needs and determine the resources required, including the position of professionals who are on duty nearby.engInformation systemsUbiquitous systemsMobile systemsINEMHealthcarejournal article
