2 International Journal of Telemedicine and Applications Furthermore several projects deal with elderly chronic disease management as CONFIDENCE [10], ATTENTIANE [11], ENABLE [12], and K4Care [13]. This paper presents the architecture of the Tile-Ippok- ratis ehealth platform. The platform covers a wide range of services: NCSR “Demokritos” Athens (i) support the collaboration and consultation between remote located health care personnel, (ii) enable the electronic monitoring of “at risk” citizens, elderly, and patients with chronic diseases, in the area of Island of Chios, (iii) home telemonitoring of post-surgery patients who had been provided intensive care medicine in the Intensive Care Unit of the Nicosia General Hospital; these patients were having Home Ventilation Care within their residents. The main objectives of the project are considering: (i) the collaboration between doctors and citizens located in Greece and Cyprus with diﬀerent health care systems, diﬀerent technology infrastructure, and diﬀerent needs, in order to enhance the quality of health care services in the region South Mediter- ranean, (ii) the improvement of the self-management skills of those patients with minimum ICT skills (the ehealth platform and their electronic personal record could be accessed by them through a web browser), (iii) the eﬃcient monitoring and health management of chronic and post-surgery patients by their doctors and the early response to emergency incidents using low-cost state-of-the-art web-based technology, (iv) the evaluation of the usability and acceptability of the proposed ehealth services in the pilot areas. The platform, which had been developed during the Interreg IIIA “Tile-Ippokratis” project: An INTEgrated pilot ehealth-platform for enhancing health care provision between Greece and Cyprus, has been tested and validated in the pilot sites in Greece and Cyprus (Figure 1). The platform and the provided services have been assessed by patients and physicians in the aforesaid sites. The platform (Server Software, EPR, Web Viewer-en- abling Internet access to patient measurements) has been installed within the premises of the National Center for Scientiﬁc Research, “Demokritos”. In the Island of Chios the platform has been used by the Skylitsio General Hospital of Chios and the rural medical peripheral health centers residing in Chios Prefec- ture Municipalities of Volysos, Kardamyla, Oinouses and Pyrgi supporting elderly citizens and patients with chronic diseases. The patients were receiving support in the rural health centres. In Cyprus the platform has been used by the Intensive Care Unit of the Nicosia General Hospital supporting post- surgery patients in the municipalities of Nicosia, Larnaca and 2.5 Gbps 155M bps “Skylitsio” general hospital Chios island Nicosia general hospital Cyprus Figure 1: Tile-Ippokratis pilot sites. Limassol. The patients were receiving support in their own homes. A summary of the various services provided per pilot site and transmitted data is presented in Table 1. The paper describes the Tile-Ippokratis architecture, the design of the entire platform, the provided services, the used systems, and the platform infrastructure (Section 2) and presents the protocol of the trials (Section 3). In Section 4, the evaluation results of the validation phase are discussed while the conclusions are presented in Section 5. 2. Platform Description The description of the platform is divided into three parts. The ﬁrst part describes the teleconsultation systems and the patients’ peripheral systems that entail the acquisition of the patients’ biosignals and their transmission to the central database server, the second part describes the remote centralized database itself, and the third part describes the network technology selected for the uploading of the data to the database. 2.1. Teleconsultation Systems and Patients’ Peripheral Systems. The Tile-Ippokratis platform provides a series of services, which have been supplied through the combined use of already evaluated systems (oﬀ the self-systems as well as systems coming out of EU-funded projects) as presented in the following paragraphs. (1) Teleconsultation Systems. The teleconsultation services have been mainly provided by the Wavelet-based INteractive Video Communication System (WinVicos). WinVicos is a high-end, interactive video conference system providing real- time video, still images, and audio transmission [14]. The system has been designed mainly for medical applications, like intraoperative teleconsultation, in various EU-funded projects. WinVicos supports communications via satellite, Local Area Network (LAN), Internet, ATM, xDSL, and so forth.
