Health care delivery is changing drastically. In its current state it tends to use the home care model in order to increase quality of life, to rationalize costs and to achieve wellness. Pivotal to these purposes are contact centers, which act as mediators between the medical staff and the citizens seeking advice and/or therapy. Main platforms used for the development of such applications are the INTERNET and PCs, and the telecommunication networks, including mobile solutions. In this paper, a generic contact center model shall be presented, which is under development in the context of an IST European project in health telematics entitled ‘Distance Information Technologies for Home care. The Citizen Health System (CHS)’. After the description of this generic contact center, an application for health care delivery to diabetic patients shall be described. In this application we shall see the possible use of the Wireless Application Protocol (WAP) scheme. This application proves the usefulness of wireless technology in providing health care services all around the clock and everywhere the citizen is located, it shows the necessity for restructuring the medical knowledge for education delivery to the patient, and it shows the virtue of interactivity by means of using the limited, yet useful browsing capabilities of the WAP technology.
