MedCom: Danish health care network.

The Danish Ministry of Health founded MedCom back in 1994. MedCom is acting as an umbrella project organisation, gathering health providers, health care professionals and industry in coordinated, nationwide projects, all aiming to reach large-scale dissemination in few years. Almost all Danish health care organisations and IT-vendors are participating in the projects and today more than 2,500 health institutions are communicating around 2.3 million messages monthly--60% of the total clinical "cross-sector" communication in Danish Health. In the next years the standards are going to be reused inside hospitals and a nationwide secure health care Internet implemented large scale.

HYGEIAnet: the integrated regional health information network of Crete.

The healthcare environment is currently changing and the health sector is being transformed to meet new challenges and to benefit from new opportunities. Priorities for the 21st century ought to be set based on emerging dominant trends in healthcare, including the shift towards shared or integrated care, in which an individual's healthcare is the responsibility of a team of professionals across all levels of the healthcare system hierarchy. In addition to the requirement for efficient and secure access to the Integrated Electronic Health Record (I-EHR) of a citizen, this necessitates the development and deployment of Regional Health Information Networks (RHINs), synchronous and asynchronous collaboration services, and novel eHealth and mHealth services, facilitated by intelligent sensors, monitoring devices, hand-held or wearable technologies, the Internet and wireless broadband communications. These further require the adoption of an open Reference Architecture and the creation of a scalable Health Information Infrastructure (HII).This paper discusses the challenges encountered in developing and deploying HYGEIAnet, the Regional Health Information Network of Crete, as well as relevant benefits for citizens and health professionals. Furthermore, HYGEIAnet systems and services are presented, with emphasis on the development of the HII and the implementation of the I-EHR service for providing secure, role-based access to validated content by authorized and authenticated users.

North Karelia regional chain of care: Finnish experiences.

Information--and communication technology is one of the most important cornerstones in more and more data and knowledge intensive health care sector. However these factors don't create financial gains and productivity benefits spontaneously. They need organisational and social innovations and new business models. The growth of productivity is connected to the process and organisational innovations and not to the number of computers and the growth of using ICT. One of the problems prohibiting health care profession to move to real e-work environment is the lack of the reliable measures and on these measures based performance measurement and strategic management. Health care can be improved by utilizing ICT and tools like performance measuring are key weapons in the arsenal of new e-work environment and measuring based new strategic management. Neither public sector nor not-for-profit hospitals look for financial rewards as their ultimate proof of success. Instead, they seek to achieve ambitious missions aimed at improving the health standards and wellbeing of the citizens. ICT- based new way of managing in the public sector is just beginning to gain a critical level of digitalization and will most likely come to its own in the coming years. Therefore, it is essential to research on how the health care sector can be moved towards new regional models and clinical workflow using intelligent standard based strategic management and performance measurement. If the breakthrough of the eight-hour working day and shortening of working time are evaluated afterwards, it can be stated that they have made the society more anthropocentric and humane. During one century the annual working time has shortened from 3000 hours to 1700 hours in the European Union countries. These foundations of a more humane society--eight-hour working day and shortening of regular working time--are however disappearing in the post-industrialized information society. There are various grounds for the eight-hour working day. These grounds relate to quality of life, occupational safety and health and productivity of work. It is worth asking if the nature of work has changed in a way that the truths of an industrialized society do not hold true or has the development of working time in health care sector become uncontrolled in some new way?

UUMA. Regional eHealth services in the hospital district of Helsinki and Uusimaa (HUS).

The UUMA approach is based on a stepwise implementation of integrated regional healthcare services to create a virtually borderless healthcare organisation--a patient centred virtual workspace. In the virtual workspace multi-professional teams and patients collaborate and share information regardless of time and place. Presently the regional ehealth network is comprised of four different integrated services between primary, secondary and tertiary care within the county of Uusimaa. The strategic healthcare modules consist of an (1) ereferral and econsultation network, (2) a knowledge-based disease management platform, (3) PACS system and (4) a universal model for integrated regional services between professionals and patients by a link directory service. The ereferral between primary and secondary care not only speeds up the transfer, but also offers an option for communication in the form of econsultation between general practitioners and hospital specialists. By sharing information and knowledge remote econsultations create a new working environment for integrated delivery of eServices between the health care providers. Last year over 60,000 eReferrals were transferred between health care providers. When associated with viewing of patient data through the link directory, interactive econsultations enable supervised care leading to the reduction of outpatient visits and more timely appointments. The link directory service extends the dimensions of networking between organizations by combining legacy systems within regional primary and secondary care. The link directory is an interface to diverse patient information systems, like HUSpacs, containing links pointing to the actual patient data located in remote information systems. The original data including images can be viewed with a web browser, but data can be accessed only with the patient's informed consent. The chronic disease management system is disease specific: information is utilised in parallel to viewing other relevant medical data through the link directory. We aim to create a new working environment for professionals by incorporation of innovative information and communication technology, new organisation of work and re-engineering of workflows. The citizen has an active role in deciding on the use of his medical information, participating in decisions on his care, carrying out guided self-care and taking steps of pro-active prevention.

SURGETICA at Grenoble: from computer assisted medical interventions to quality inspired surgery.

Research on "Computer Assisted Medical Interventions" (CAMI) was initiated in Grenoble in 1984, as an attempt to take up the challenge of "Minimally Invasive Interventions", thanks to the introduction of Information and Communication Techniques in the Operating Room. In a first section, we will describe our initial vision. The corresponding achievements will then be presented. A final section will show that the challenge now is to "invert this movement": instead of moving the computer in the Operating Room, we should embed the surgeon (or at least his or her expertise) into the Information Technology based tools he or she uses.

How wearable technologies will impact the future of health care.

After four hundred years of delivering health care in hospitals, industrialized countries are now shifting towards treating patients at the "point of need". This trend will likely accelerate demand for, and adoption of, wearable computing and smart fabric and interactive textile (SFIT) solutions. These healthcare solutions will be designed to provide real-time vital and diagnostic information to health care providers, patients, and related stakeholders in such a manner as to improve quality of care, reduce the cost of care, and allow patients greater control over their own health. The current market size for wearable computing and SFIT solutions is modest; however, the future outlook is extremely strong. Venture Development Corporation, a technology market research and strategy firm, was founded in 1971. Over the years, VDC has developed and implemented a unique and highly successful methodology for forecasting and analyzing highly dynamic technology markets. VDC has extensive experience in providing multi-client and proprietary analysis in the electronic components, advanced materials, and mobile computing markets.

New paradigms in telemedicine: ambient intelligence, wearable, pervasive and personalized.

After decades of development of information systems dedicated to health professionals, there is an increasing demand for personalized and non-hospital based care. An especially critical domain is cardiology: almost two third of cardiac deaths occur out of hospital, and victims do not survive long enough to benefit from in-hospital treatments. We need to reduce the time before treatment. But symptoms are often interpreted wrongly. The only immediate diagnostic tool to assess the possibility of a cardiac event is the electrocardiogram (ECG). Event and transtelephonic ECG recorders are used to improve decision making but require setting up new infrastructures. The European EPI-MEDICS project has developed an intelligent Personal ECG Monitor (PEM) for the early detection of cardiac events. The PEM embeds advanced decision making techniques, generates different alarm levels and forwards alarm messages to the relevant care providers by means of new generation wireless communication. It is cost saving, involving care provider only if necessary and requiring no specific infrastructure. This solution is a typical example of pervasive computing and ambient intelligence that demonstrates how personalized, wearable, ubiquitous devices could improve healthcare.

On-body diagnosis for wearable systems serving biomedical needs.

Early diagnosis as well as a healthy and preventive lifestyle can help slowing the onset of many health problems and save millions of lives per year. To achieve this objective, long-term monitoring of human vital signs are required to obtain knowledge on a person's health status. Continuous monitoring of vital signs is mandatory, but continuous transmission is expensive, in terms of financial costs as well as power consumption for battery operated portable systems. Clothing is like a second skin to us: intelligent biomedical clothes may make everyday life easier for people in poor health, helping them to lead productive lives, senior citizens and also for athletes. Clothing means fashion and fun: smart clothes will combine health problem prevention, entertainment, comfort, convenience and communication with fashion. This paper presents essential issues in wearable electronics, including interface with the garment, signal sensing and enhancement, signal processing of signal combination, on-body diagnosis and on-body and distant communication. The paper reports on experience acquired through related projects running at the Swiss Center for Electronics and Microtechnology.

Enhanced communication between care professionals and patients with hemophilia by using a web enabled electronic logbook.

Hemophilia is an X-linked clotting disorder. Treatment consists of intravenous substitution of the missing clotting factor. Although very effective, clotting factor products are very expensive. Most of the clotting factors are administered at home by the patients themselves. Documentation of the amount used and reasons for administrating of these scarce and expensive clotting factors in a paper logbook is a problem. The use of an electronic logbook results in improved compliance in documentation of clotting factor use and therefore in improved quality of treatment of patients with hemophilia.

Clinician style and examination room computers: a video ethnography.

BACKGROUND AND OBJECTIVES: The use of computers in medical examination rooms is growing. Advocates of this technology suggest that all family physicians should have and use examination room computers (ERCs) within the near future. This study explored how family physicians incorporate the use of ERCs in their interactions with patients. METHODS: This qualitative study involved five family physicians, one family nurse practitioner, and a convenience sample of 29 patients. Data included videotaped visits, clinician interviews, and videotape reviews. The setting was an urban family practice with a 7-year history of viewing electronic medical records. The main outcome measures were themes emergent from videotaped data. RESULTS: We identified three distinct practice styles that shaped the use of the ERC: informational, interpersonal, and managerial styles. Clinicians with an informational style are guided by their attention to gathering data as prompted by the computer screen. Clinicians with an interpersonal style focus their attention and body language on patients. Clinicians with a managerial style bridge informational and interpersonal styles by alternating their attention in defined intervals between patients and the computer. CONCLUSIONS: Family physicians have varying practice styles that affect the way they use examination room computers during visits with patients.

Libraries of strategies and ontology-driven subject area models as "corner stones" in Grid development.

Series of experiments of Grid-based calculations by Monte-Carlo simulation of molecular conformations have shown that there are classes of problems that could be "gridified" in short time with reasonable efforts. That could awake serious interest in the Grid from the biophysics and biochemistry community. Experiments with scientific problems that include both intensive computations and intensive data interchange have shown that libraries of strategies could provide an effective tool to adapt Grid-node infrastructure to problem structure. Libraries of strategies on different levels of Grid hierarchy--from local clusters to regional segments--could provide an effective usage of Grid resources. Ontologies provide a universal tool to link distributed databases. Besides, ontologies also allow for the formal construction of models of subject areas. These models are the tools to formalize information requests and to construct intellectual queries to information space. There should be a multi-level hierarchy of ontologies and a critical mass of low-level ontologies must be reached in order to build a knowledge space for a subject area.

An OGSA-based integration of life-scientific resources for drug discovery.

OBJECTIVES: The rapid progress of life-scientific research has the potential to dramatically change the paradigm of drug discovery. Efficient utilization of life-scientific resources, i.e., databases and analytic software tools, poses a challenging issue with regard to the reduction of time and cost in the drug discovery process. In this paper, a variety of heterogeneous Web-based life-scientific resources are integrated toward the improvement of drug discovery performance. METHODS: For the integration of heterogeneous life-scientific resources, a database federation technique based on three-layer architecture has been utilized. With the federation technique, life-scientific resources are integrated step by step through database layers, database integration layers and analysis layers to encapsulate complexity and heterogeneity. In this study, we have taken advantage of the latest Grid technology based on OGSA (Open Grid Services Architecture) for the implementation of our approach. RESULTS: The actual case of life-scientific resources for drug discovery demonstrates that our prototype system developed with the proposed technique works well for the identification process of candidate compounds to a target protein. In other words, the prototype system allows a researcher to retrieve candidate compounds with less effort than before. CONCLUSIONS: The usefulness of the prototypic system represents the ability of our approach to integrate heterogeneous life-scientific resources, which have the potential to dramatically improve efficiency in drug discovery, resulting in the shortening of drug development. On the other hand, the system requires further consideration from the aspect of practical use. Dynamic aggregation of the resources is one example of such a consideration.

A framework supporting the development of a Grid portal for analysis based on ROI.

OBJECTIVES: In our research on brain function analysis, users require two different simultaneous types of processing: interactive processing to a specific part of data and high-performance batch processing to an entire dataset. The difference between these two types of processing is in whether or not the analysis is for data in the region of interest (ROI). In this study, we propose a Grid portal that has a mechanism to freely assign computing resources to the users on a Grid environment according to the users' two different types of processing requirements. METHODS: We constructed a Grid portal which integrates interactive processing and batch processing by the following two mechanisms. First, a job steering mechanism controls job execution based on user-tagged priority among organizations with heterogeneous computing resources. Interactive jobs are processed in preference to batch jobs by this mechanism. Second, a priority-based result delivery mechanism that administrates a rank of data significance. RESULTS: The portal ensures a turn-around time of interactive processing by the priority-based job controlling mechanism, and provides the users with quality of services (QoS) for interactive processing. The users can access the analysis results of interactive jobs in preference to the analysis results of batch jobs. The Grid portal has also achieved high-performance computation of MEG analysis with batch processing on the Grid environment. CONCLUSION: The priority-based job controlling mechanism has been realized to freely assign computing resources to the users' requirements. Furthermore the achievement of high-performance computation contributes greatly to the overall progress of brain science. The portal has thus made it possible for the users to flexibly include the large computational power in what they want to analyze.
