System integrational and migrational concepts and methods within healthcare.

In this paper an overview and comparison of the basic concepts and methods behind different system integrational implementations is given, including the DHE, which is based on the coming Healthcare Information Systems Architecture pre-standard HISA, developed by CEN TC251. This standard and the DHE (Distributed Healthcare Environment) not only provides highly relevant standards, but also provides an efficient and well structured platform for Healthcare IT Systems.

Security of healthcare information systems based on the CORBA middleware.

The development of healthcare systems in accordance to the "Shared Care" paradigm results in co-operative health information systems across the boundaries of organisational, technological, and policy domains. Increasingly, these distributed and heterogeneous systems are based on middleware approaches, such as CORBA. Regarding the sensitivity of personal and medical data, such open, distributed, and heterogeneous health information systems demand a high level of data protection and data security, both with respect to patient information and with respect to users. The security concepts and measures available and additionally needed in health information systems based on CORBA architecture are described in this paper. The proposed security solution is also open to other middleware approaches, such as DHE or HL7.

Potential for the usage of information technologies and communications (ITC) in the teaching and practice of nurses in Madeira.

The propose of this communication is to describe the present nursing situation in Madeira (RAM) and its potentialities for the utilisation of the Information Technologies and Communications (I.T.C.) in educational and in clinical practice. RAM has its own Regional Health System and is developing a Health Information System, a Nursing Education System which conglobates a Baccalaureate Nursing School and a Licentiate's degree Nursing School which graduates almost the totality of the nurses who work here in Madeira, a Health Professional Education Department, common to the different organisations and a Regional Nursing Research Group constituted by elements representing the several organisations of health and which has been developing Research Education and dynamize Research Projects in nursing practice. The Nursing Schools in addition to the Health Organisation, use the Nursing Theoretical Models and the Nursing Process since 1990 Referring to the utilisation of the ITC in Education and in the Clinical Practice, despite the school curricula include informatics subjects, nurse's knowledge and opportunities of utilisation are still too incipient. Nevertheless, the present reform of the baccalaureate course curriculum as well as the aims and strategies of the Nursing Research Group and training strategies will provide positive changes.

Security of medical image databases.

Medical images are an integral and indispensable part of health care information systems. Because of the critical nature of image information and stringent privacy requirements in medical environments, the medical images database systems must provide reasonable safeguards to assure confidentiality, integrity and availability of images to be deployable. In this paper we address mainly the confidentiality issues. Only authorized users should have for example access to medical images. Access to images is usually based on certain security constraints. Security constraints processing is a widely used mechanism for obtaining the appropriate level of the security required in traditional (non-multimedia) database systems. However, the security constraints processing in multimedia environments possess a number of interesting problems. In this paper we address the advantages and problems of using content-based security constraints on medical image databases. We also propose a methodology for the integration of security constraints into medical image databases, taking into account the true multimedia nature of the medical images (e.g. the content of the medical images).

A platform independent teleradiology system based on Web services.

This paper describes NetRad, a Teleradiology application based on an open, non-proprietary architecture implemented using only Web and Java technologies. A comparison with other proprietary teleradiology systems suggests that the proposed solution is attractive, being completely independent of the hardware and software platform. This architecture allows easy maintenance and fast development of new distributed capabilities. Finally, it is based on a user interface paradigm widely known and accepted all over the World.

The knowledge model of MedFrame/CADIAG-IV.

The medical consultation system MedFrame/CADIAG-IV is a successor of the prior CADIAG projects. It is the result of a complete redesign to account for today's demands on state-of-the-art software. Its knowledge representation and inference process are based on fuzzy set theory and fuzzy logic. Fuzzy sets are used for conversions from measured numeric values and observational data into symbolic ones. Medical relationships between findings, diseases, and therapies, the rules, are represented by fuzzy relations, that express positive or negative associations. Findings, diseases, and therapies are organised in hierarchies.

ARMEDA: accessing remote medical databases over the World Wide Web.

We have created a computer system to access medical information located at remote databases over the World Wide Web, for epidemiological ad health services research. We made a preliminary prototype where a specific database model could be searched and information be retrieved. We are currently working on a new component-based architecture, where different databases scheme from various sites can be used to create a unified model, giving users a "virtual" vision of a single, local database. Different software engineering and artificial intelligence methods are used to access, integrate, filter and deliver information to users.

Using World Wide Web technology for educating students in the health care sector.

The Internet was born in December of 1969 and has grown phenomenally since. Its graphically interactive, user-friendly modality, the World Wide Web (WWW), is younger and growing even more explosively. By its nature, the WWW is a tool ideally and uniquely suited for the advancement education. This paper describes the design, development and the implementation of a Web Site for supporting the education of the students in the Faculty of Nursing at the University of Athens.

A distributed support system for medical and nursing students.

The Internet provides resources for physicians, but there isn't yet a comprehensive support system for medical and nursing students. Moreover the knowledge of English language is often scarce in young Italian students, so most of the available resources are not really useful. This project aims at the establishment of a distributed framework of interactive courses and mentoring facilities among a group of Italian Medical and Nursing Schools.

Designing medical hypermedia: the FORUM project.

Medical activity in learning stages or in usual tasks is a wide field for information technologies. But it would be a mistake to focus on technologies and minimize the organisational, social and cultural aspects of integrating such technologies. Medical hypermedia design based only on a technological approach is a case in point. This paper describes our experience in hypermedia development. It reports on the technical, methodological and organizational aspects destined to help the medical community get involved in the development of such applications.

From electronic medical record to personal health record.

In this paper we attempt to provide a definition and purpose for the electronic patient record, point out the benefits of its use and outline the major challenges in wider implementation that are encountered world-wide. Finally, some trends are highlighted that are believed to play an important role in the future development and use of the electronic patient record.
