    Better health care for all and an overall health care restructuring are two of the most important processes that, in addition to many existing assignments, expose many new tasks and responsibilities for nursing personnel. Each of these responsibilities entails information as input and also generates information as the output, and in the near future it is to be expected that most of the information processing, including data gathering, decision-making support, data mining and information generation will be performed by computers. To cope with this new situation, nurses have to be armed with the proper knowledge, and thereafter the proper education will play a very important role. In this manner, we started an EU project called NICE (Nursing Informatics and Computer-aided Education), one of the main objectives of which is to develop new computer-managed instructional (CMI) tools for nursing View full abstract»

  • Multi modal presentation in virtual telemedical environments

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (16 KB)  

    Summary form only given, as follows. Telemedicine can be used to create virtual environments for the collaboration of patients, physicians and medical staff. Multimodal presentation is increasingly used to improve the human-computer interface. In this paper, we present a multimodal interactive environment for EEG/MEG data presentation based on Internet technologies and a virtual reality user interface (VRUI). In addition to visualization, the VRUI takes advantage of other input/output modalities, such as audio. Animation of the 3D models is used to give insight into spatio-temporal patterns of activity. In addition, sonification is applied to emphasize the temporal dimension of the selected visualised scores. Our proposed approach requires only a standard Web browser to run the multimodal viewer, which presents 3D EEG topographic maps using a VRML head model which is animated with Java applets View full abstract»

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (196 KB)  

    No study to date has addressed the integration issues of the wavelet-based compression techniques with the design and functionality issues of mobile telemedicine systems for real-time medical data transmission over cellular channels. This paper addresses such new hybrid methodologies, namely new wavelet compression methods integrated with the modular telecommunication design blocks and relevant hardware DSP structures for enhanced integrated wireless telemedical systems. I first describe wireless mobile communication in the health sector, discuss the trends in future personal communication services and highlight the actual uses of mobile communications and telematic services in the healthcare domain. The design and integration issues of mobile telemedicine applications based on European (GSM) and North American (IS-136) cellular telephone standards, detailing the modelling and design issues of a general modular structure of a GSM-based mobile telecardiology system are presented. I then address the wavelet compression issues and new signal-processing algorithm methodologies that can be integrated within the wireless design process to optimise the performance and to enhance the integration and adaptability of such systems under different mobility conditions. These concepts provide the telemedicine providers with a better understanding of the engineering aspects and the compatibility issues of future mobile standards and their integration with the next generation of mobile telemedicine applications for enhanced quality and better performance and flexibility of mobile telehealth systems View full abstract»

  • Some methodological issues in telemedicine: systems, modeling and evaluation

    Page(s): 11 - 12
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (92 KB)  

    Telemedicine, including the provision of telematic health care services, is already playing a significant role in transforming the practices of health care delivery and has the potential to bring about what is truly the “hospital without walls”. However, if this potential is to be fully realised, it is vital that proper systemic and systematic methodologies be adopted for the design, development and evaluation of telematic health care systems. This paper addresses a number of such methodological issues. First, in relation to specification and design, it is shown how systems-based models can and do offer a paradigm for tackling these stages of system development. The role of the telematic system as an extension of the feedback processes involved in clinical activity can be clearly portrayed and the full range of system users and other stakeholders identified. Evaluation must be seen as an integral part of the system cycle, with again models being central to a process that can be treated in terms of evaluability, formative evaluation and summative evaluation. Evaluation criteria can be divided into a necessary sub-set, where a Boolean model may be adopted, and an additional set to provide sufficiency, where a Bayesian approach may provide a means of combining dissimilar measures of performance. The relevance and applicability of the methodological concepts discussed are illustrated with reference to the EU-funded health care telematic project HOMER-D. This involves the specification, design, implementation and evaluation of a telematic system to support home or satellite haemodialysis services View full abstract»

    The Information Era we live in has created new challenges and opportunities. This age of information highways has an economic price which has not been properly evaluated. Detailed studies are needed to prove the cost and medical effectiveness of these technologies, as well as their effects on the quality of life. Our society's future may depend on it. People are living longer, while discoveries in genetics and in information technology are not only helping to produce newer drugs faster but are also providing the opportunity to exploit new areas such as disease prevention. These technologies provide a variety of opportunities to address public health challenges, such as universal access for the uneducated, counter-bioterrorism, telemedicine, distance education and home care. These opportunities present new challenges, such as surveillance and the privacy/confidentiality/security of personal information which will affect all of our lives. No strategy has been presented publicly yet, addressing the benefits or the pitfalls of such technologies View full abstract»

    Demonstrates the impact that Web technologies and meta-computing can have on the simulation of biological processes such as tumor growth. A client-server architecture allowing real-time surface and volume rendering using a standard Web browser is proposed. A simplified 3D cytokinetic simulation model of tumor growth in vitro is developed, and results are obtained concerning the development of a small-cell lung cancer (SCLC) tumor spheroid in cell culture. A Gaussian distribution of the cell cycle phase duration is considered. The behavior of the model is compared with both published data and laboratory experience. The application of Web technologies and meta-computing leads to a spectacular 3D visualization of both the external and the internal structure of a growing tumor spheroid View full abstract»

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (60 KB)  

    The 3DHeartview project produced an advanced prototype of a system capable of modeling 3D cardiac structures, based on a single sequence of clinical angiographic X-rays, that can be used as an add-on to any modern digital angiography system. The system's accuracy has been measured, and our approach has been used in many real patient cases in a clinical routine environment. In this paper, we present the main features of the system, the methodology of 3D angiographical modeling, and certain testing and operation results. We also describe the application of high-performance computing (HPC) technology in the modeling process View full abstract»

  • Biomedical information technology: from digital dawn to NGI

    Page(s): 4 - 6
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (112 KB)  

    Presents an overview of the IT roadmap as we move from basic Internet to next-generation Internet (NGI) initiatives and from the information-centric to the knowledge-centric paradigm. Medicine and health care issues are discussed in light of these developments. With the continuing evolution of the numerous technologies and their support components, medicine and health care are in the midst of a major paradigm shift to embrace the Electronic Age. As these disciplines constantly generate new requirements, we stand poised to invent new protocols and technologies that support new problems. Over the past decade, the technology path has taken us through major infrastructure transitions. These developments have had significant impact on the R&D and information infrastructure aspects in biomedicine. While the Internet provides access to hundreds of thousands of globally distributed and heterogeneous information repositories and information resources, it is critical that we build an efficient information retrieval infrastructure to organize these distributed repositories into a coherent collection as well as manage the billions of digital objects that constitute these databases. Current research on digital libraries addresses such issues with the goals to efficiently capture, store, organize, search, process and retrieve knowledge from electronic collections containing text, images and multimedia clips. Intelligent integrated systems, knowledge management and data mining are areas that are currently being explored View full abstract»

  • Business aspects of trusted third party services in Europe

    Page(s): 38 - 39
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (464 KB)  

    The concept of “trusted services” forms a key issue for any type of electronic service. The author highlights the current business perspectives of the European trusted services market. In telehealth care, as in other kinds of services delivered via open networks, security plays a dominant role. The Business Environment Study of Trusted Services (BESTS) indicates that trusted services are essential for Europe's growth into the information society, and that therefore it should have native competence in trusted services. E-commerce and e-services are really taking off to such an extent that all of them need trusted third-party services to organize their business in a proper way. The main players traditionally consist of the certification authorities, insurance companies, postal and telecommunication services, governments, banks, chambers of commerce, and so on. Although regulation is still very unclear, many pilot projects are being launched, but there are very few real implementations at the moment. In any case, the author anticipates that trusted services are entering into a growth market View full abstract»

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (72 KB)  

    With the rapidly increasing development of telemedicine technology, the evaluation of telemedical services is becoming more and more important. However, professional views of the aims and methods of evaluation are different from the perspective of computer science and engineering compared to that of medicine and health policy. We propose that a continuous evaluation strategy should be chosen which guides the development and implementation of telemedicine technologies and applications. The evaluation strategy is divided into four phases, in which the focus of evaluation is shifted from technical performance of the system in the early phases to medical outcome criteria and economical aspects in the later phases. We review the study design methodology established for clinical trials assessing therapeutic effectiveness and diagnostic accuracy, and discuss how it can be adapted to evaluation studies in telemedicine. As an example, we describe our approach to evaluation in a teleconsultation network in ophthalmology View full abstract»

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (52 KB)  

    Basically, the medical diagnosis process can be interpreted as a decision-making process, during which the physician induces the diagnosis of a new and unknown case from an available set of clinical data and from his/her clinical experience. This process can be computerized in order to present medical diagnostic procedures in a rational, objective, accurate and fast way. In fact, in the last two or three decades, diagnostic decision support systems have become a well-established component of medical technology. In this paper, we address our attention to the early detection of cancer on the basis of a small amount of clinical information. In order to develop a decision support system in this specific context, we emphasise the powerful efficiency and effectiveness of mathematical programming approaches as basic tools for developing medical diagnostic decision support systems View full abstract»

    The emerging European “Virtual Medical Worlds Community” (VMWC) is aimed at advancing the use of advanced technology in telemedical applications. The working group consists of European companies and academic groups who are active in high-performance computer networking (HPCN), databases, virtual reality (VR) and telemedicine, and academic groups and companies with business in telemedicine and other medical applications requiring these advanced techniques. The VMWC working group will bring together technology suppliers with users in this focused medical sector. The working group will stimulate exchange of information and expertise, and create awareness in the medical sector, thus advancing European industry in the above-mentioned areas. VMWC will organise workshops, technical meetings and a virtual community environment on the Internet for exchange amongst the members. For dissemination, VMWC will be present at major telemedical events, maintain the VMW Web site and support the VMW magazine and distribute it amongst its relations. VMWC will work closely together with and build upon related activities in other areas: Euromed, HOISe/Primeur and HPCnet. Euromed provides the standardization which is important for the emerging industry that will create the telemedical information society. HPCNet provides a platform for HPCN technology-related issues. The HOISe/Primeur consortium provides news and discussion platforms for the HPCN and telemedical sectors. VMWC will capitalize on these initiatives and bring together the activities in the relevant disciplines that contribute to telemedicine View full abstract»

    Some innovations are adopted quickly and are widely used; others never seem to find widespread acceptance. Among the many factors related to the diffusion of innovations are sociodemographic, psychological and communications variables. This examination of three groups of physicians who adopted innovations and changed some aspect of their medical practice identifies the common characteristics of younger age (or younger professional age), board certification or specialization, increased information-seeking behavior and increased contact with opinion leaders View full abstract»

    Virtual Medical Worlds (VMW) represents a new standard for integrating together medical information that may reside at several different locations, be of many different modalities, and adapt automatically to new information. A particularly important source of medical information is medical images, nowadays mostly stored in DICOM databases. We present and demonstrate an integrated system that allows Web-based access to DICOM images from the Virtual Medical Worlds interface, and that provides for semi-automatic incorporation of new image information into the VMW template, as soon as the images are entered into the DICOM database View full abstract»

    The EC ISIS '95 Euromed project has now completed its three-year duration. It has proposed a framework to establish a complete advanced medical society using Web-based telemedicine called ITIS (International Telemedical Information Society). Euromed has also spawned a number of collaborative ventures, such as the ITIS conference, the Journal of ITIS Letters and the VMW (Virtual Medical Worlds) magazine. One of the major achievements of the Euromed project was to propose a standard to integrate the diverse range of telemedical technologies and applications. This standard is called Virtual Medical Worlds (VMW). The Euromed project is now looking to move to the next stage of development: the implementation and establishment of a pilot (testbed) society where all the related techniques, applications and technologies can be installed and observed View full abstract»
