- KonferenzbeitragAnonymity preserving authorization granting in medical information networks(European Conference on eHealth 2006, 2006) Eskeland, Sigurd; Oleshchuk, VladimirDue to the sensitivity of personal medical information, this paper addresses the need of hiding patient identities - in contrast to only keeping their medical data confidential. Thus, it is desirable that personal and meaningful patient identity information like names, addresses, personal identity numbers, etc., are not to be linked to disclosed electronic patient records (EPR). To achieve this, we propose a scheme that enables patients to anonymously grant medical teams authorization to access their EPRs without revealing their identities to the teams providing medical care. An essential benefit is that it enables patients to exert control over their own medical data. A security evaluation is included.
- KonferenzbeitragBalancing of Benefits and Disadvantages using IT-integration to support the health care value-added chain(European Conference on eHealth 2007, 2007) Konrad, Walser; Peter, HaasThe implementation of national eHealth interoperability platforms is one answer to the problematic financial situation of health care systems in many places. Using IT-supported integration between IT systems and processes of health care institutions should make the health care value-added chain more effective and more transparent. This article will present the capabilities for interoperability in the integration of added-value in connection with the benefits and disadvantages, which arise from the various players (with diverse characteristics in some circumstances). A better consideration of the balancing of disadvantages or benefits of the IT-supported integration in health care value-added chain can lead to increased preparedness on behalf of the health care institutions to the development and financing of interoperability platforms.
- KonferenzbeitragBuilding a smart hospital using RFID technologies(European Conference on eHealth 2006, 2006) Guinard, Patrik Fuhrer DominiqueTechnologies of identification by radio frequencies (RFID) experience a fast development and healthcare is predicted to be one of its major growth areas. After briefly introducing the common terminology of the RFID field and its current standards, this paper describes how this emerging technology can be used to build a smart hospital. Indeed, used in combination with mobile devices in eHealth applications, RFID helps optimizing business processes in healthcare and improve patient safety. The second part of this article shows how to use an assets tracking application, called the RFIDLocator, to improve the quality of the hospital services. We developed the RFIDLocator to support the high requirements for scalability and reliability one can expect for such an application. An overview of its distributed software architecture is given. A short cookbook presents the required steps for its configuration to the concrete case of the hospital. Some critical remarks about RFID technology, the important questions it raises and the barriers it has to overcome to be fully integrated in eHealth applications conclude this paper.
- KonferenzbeitragBuilding flexible eHealth processes using business rules(European Conference on eHealth 2006, 2006) Hüsemann, Stefan; Schäfer, MikeThis article describes how business agility in a health insurance company can benefit from more flexible business processes. The suggested architecture for a flexible information system is service-oriented and uses a business rule management system to externalize rules. At the organizational level the business rule approach helps to identify and formalize rules.
- KonferenzbeitragCARA-D: Data Elements for a Computer based Cancer Risk Assessment System(European Conference on eHealth 2007, 2007) Yang, Gi-Chul; Oh, Haeng-UnData elements are important part of a computer based cancer risk assessment system. The selection of the data elements are more important for the system built based on Case Based Reasoning (CBR) technology. The system CARA is a computer based cancer risk assessment system that adapts CBR technology. The data elements and an overall architecture that can assure high performance of the CARA are described in this article.
- KonferenzbeitragThe challenges of electronic prescription systems based on semantic web technologies(European Conference on eHealth 2006, 2006) Puustjärvi, Juha; Puustjärvi, LeenaThe technology developed for interoperable autonomous systems has significantly changed during the past few years. However, this new technology based on Semantic Web is not yet deployed in electronic prescriptions systems. On the other hand, during the past few years several organizations in the healthcare sector have produced standards and representation forms using XML. This generalization of XML-technologies sets a promising starting point for the interoperability of the various organizations in the healthcare sector. However, the introduction of XML is not enough but many other XML-based technologies have to be introduced in order to achieve a seamless interoperability between the electronic prescription systems and other organizations of the health care sector. In this article we illustrate the querying facilities that the deployment of the semantic web technology can provide for electronic prescriptions systems. Furthermore we illustrate the system architecture and the ontologies as well as the ontology specification languages that are required in implementing an electronic prescription system based on semantic web technologies.
- KonferenzbeitragA Comprehensive Modeling Language for Clinical Processes(European Conference on eHealth 2007, 2007) Faerber, Matthias; Jablonski, Stefan; Schneider, TobiasIn this paper we present a comprehensive modeling language for clinical processes that integrates requirements from the medical, organizational and economical dimension into a single clinical process model. The design of this modeling language is heavily influenced by the experiences we made when documenting the processes at several clinics in Germany. Thus, we introduce the features of this modeling language by examples. We show that extensibility is one of the key features of this type of domain specific language and describe the principle idea of its implementation in the second part of the paper.
- KonferenzbeitragContext-aware secure service composition planning and execution on e-Health environments(European Conference on eHealth 2006, 2006) Lopes, António; Costa, Paulo; Bergenti, Federico; Klusch, Matthias; Blankenburg, Bastian; Möller, Thorsten; Schuld, HeikoEmergency Health-Care based scenarios provide the motivation to develop supporting technologies for dealing with situations where people need medical assistance because of a sudden disease or emergency. The innovative combination of intelligent agent technology, semantic Web services, peer-to-peer, and mobile computing for intelligent peer-to-peer mobile service environments is the corner stone of the CASCOM project, which aims at providing a value-added support for business services for mobile workers and users across mobile and fixed networks, especially for e-Health environments. In this paper, we describe the technical approach developed in the CASCOM project for the context-aware secure composition planning and execution of Semantic Web Services.
- KonferenzbeitragContext-aware service coordination for mobile e-Health applications(European Conference on eHealth 2006, 2006) Bergenti, Federico; Caceres, Cesar; Fernandez, Alberto; Fröhlich, Nadine; Helin, Heikki; Keller, Oliver; Kinnunen, Ari; Klusch, Matthias; Laamanen, Heimo; Lopes, António; Ossowski, Sascha; Schuldt, Heiko; Schumacher, MichaelIn this paper, we present a general architecture for service delivery and coordination in intelligent peer-to-peer (IP2P) environments that has been developed within the CASCOM research project. Our essential approach is an innovative combination of agent technology, Semantic Web Services, peer-to-peer, context-awareness, and mobile computing for intelligent peer-to-peer mobile service environments. Services are provided by software agents exploiting the coordination infrastructure to efficiently operate in highly dynamic environments. Our infrastructure includes efficient communication means, support for contextaware adaptation techniques, as well as dynamic service discovery and composition planning. For end users, the architecture provides seamless access to Semantic Web Services anytime, anywhere, and using any device. Our architecture is being evaluated using a sample ad-hoc emergency healthcare assistance application scenario. We deployed a prototype of an open IP2P service environment and expect results on methods for service provision, discovery, composition, and monitoring in mobile environments.
- KonferenzbeitragA data network for health e-Research(European Conference on eHealth 2006, 2006) Taylor, Kerry; O'Keefe, Christine M.; Colton, John; Baxter, Rohan; Sparks, Ross; Cameron, Mark; Lefort, Laurent; Srinivasan, UmaSharing health data for research purposes across data custodian boundaries poses technical, organisational and ethical challenges. We describe a service oriented architecture for a proposed Health Research Data Network (HRDN). The HRDN architecture supports services to manage data access and use by researchers in accordance with individual data custodian policies. The capabilities of the HRDN architecture are described using a layered service model. The four abstract layers from lowest level to the highest level are 1) Preparing, 2) Storing, 3) Sharing and 4) Using. Two additional groups of services are interfaced with the services in each of the four layers. They are 1) Describing, with services for collecting and managing metadata, and 2) Protecting, with services for ensuring confidentiality and privacy protection, as well as services and tools implementing information security functions. In addition to these HRDN service groups, client-side applications are used by data custodians, service providers and researchers. Following a reference implementation of most services and the Researcher's Workbench, a commercial version of the software has been developed and is being trialled.
