An example of usability measurement in clinical software procedures.

As a consequence of the dramatic improvements achieved in information technology standards in terms of single hardware and software components, efforts in the evaluation processes have been focused on the assessment of critical human factors, such as work-flow organisation, man-machine interaction and, in general, quality of use, or usability. This trend is particularly valid when applied to medical informatics, since the human component is the basis of the information processing system in health care context. With the aim to establish an action-research project on the evaluation and assessment of clinical software procedures which constitute an integrated Hospital Information System, the authors adopted this strategy and considered the measurement of perceived usability as one of the main goals of the project itself: the paper reports the results of this experience.

[Information technology and medical record routines in hospitals in the health care region 2].

Structure, standard and efficient methods in paper medical records are important for a successful implementation of computerised medical records. We have conducted a survey among 26 somatic hospitals in a Norwegian region regarding present routines and use of information technology in patients records. The hospitals use six different patient administration systems, six laboratory, six radiology, and approximately 20 different specialist systems. 16 hospitals use three different electronic journal/documentation systems. Ten hospitals use the Word word processor for patient records. The full potential of word processing is not utilised. Digital dictation is seldom used; few hospitals have 24-hours service for documentation, and information technology is not used for documentation in nursing care. Four hospitals use microfilm. The survey shows that improvement is needed in order to achieve coordinated and effective use of information technology and manual routines in hospital medical records.

[Which health information systems for the evaluation of health actions?].

The evaluation of health actions requires large amounts of information allowing an assessment of relevance, coherence, efficacy, efficiency and impact of these interventions. Information systems should support evaluation processes by helping to obtain pertinent indicators, tracers and standard operating procedures. To reach this objective, specific functions need to be implemented, including traceability, documentation, investigation and scientific awareness. But this supposes that health information systems respect quality criteria that this article defines. The following criteria are considered: simplicity, validity, acceptability, informative value, representativeness, continuity, reactivity, fluidity, flexibility of the system, and also confidentiality of information. The historical developments of medical informatics have induced the creation of independent information systems, answering to specific objectives. This lack of integration is an obstacle to the evaluation of health actions because of the difficulty to view transversally and longitudinally the sequence of actions for a same patient. Thus integrated health information systems, organised around patient care episodes, are necessary to support evaluation and to contribute effectively to decision making in public health, because the evaluation of health actions implies the availability of information about the individuals who are the targets of these actions.

Tracing technology in the Association of Academic Health Sciences Libraries.

From the beginning of the association, technology and the Association of Academic Health Sciences Libraries (AAHSL) have been intertwined. Technology was the focus of one of the first committees. Innovative applications of technology have been employed in the operations of the association. Early applications of mini-computers were used in preparing the Annual Statistics. The association's use of network communications was among the first in the country and later applications of the Web have enhanced association services. For its members, technology has transformed libraries. The association's support of the early development of Integrated Advanced Information Management Systems (IAIMS) and of its recent reconceptualization has contributed to the intellectual foundation for this revolution.

Creating the integrated information infrastructure for the 21st century at the University of Washington Warren G. Magnuson Health Sciences Center.

Successful integrated information systems implementation requires an effective marriage of technology and information resources in response to critical institutional needs. The University of Washington technical infrastructure, developed over the past five years, includes ubiquitous, high-speed network access throughout the Health Sciences Center and hospitals, agreement on network standards and protocols, uniform interface to common databases (character-based and GUI) and network availability of a variety of databases and information resources at no charge to the individual. As a result of this heavy institutional investment in technical infrastructure, our implementation process will focus on expanding the number of available resources as well as developing and refining tools and services to enhance the utility of electronic information resources. Above all we will study and develop strategies for dealing with the myriad of information policy issues which confront and confound us all today.

Integrating PACS power.

While the technology side of PACS is strong, it's the way you implement your PACS--and especially the way you integrate your PACS with your hospital and radiology information system--that makes all the difference.

The bridge between administrative and clinical information system.

On one side, physicians are asked to record administrative information, such as activity measurement, case-mix of their specialty, billing, for statistical, legal or reimbursement purposes; and on the other side, they need to gather detailed information about their own patients in terms of clinical evolution, for the day-to-day care of the patients or for clinical research purposes. Many other actors are also involved with these processes, both on the administrative side, such as registration officers, administrators and on the clinical side, nurses and other care providers. Applications have been developed within hospital information systems for capturing and disseminating information according to these specific actors and dedicated purposes. But more and more appears the need to integrate these data for insuring the coherence of information and avoiding redundancy of data capture. How to conciliate these objectives? We describe the Geneva's approach for integrating the administrative and the clinical systems.

XML-based application interface services--a method to enhance integrability of disease specific systems.

Disease specific systems usually offer excellent functionality for the management of the covered diseases. But the restriction to a certain disease often hampers their wide spread use since they are not optimised for clinical workflow. The Giessener Tumordokumentationssystem (GTDS) is a disease specific system that is not only designed for the use in tumour registries but also to support clinical care. In order to integrate it into hospital information systems, we implemented standard communication interfaces. However, interfaces are not satisfactory since they do not consider aspects of the normal workflow of a clinical user. Therefore, we developed a strategy that should ease the access to the system in the environment of existing systems. From the technical point of view, XML with its capabilities to represent even complex data in a rather simple way helped to implement this strategy. We use XML to communicate with API-like services and created a WWW environment to demonstrate the access to these services. Since HTML based access itself is a means to integrate systems, we intend to expand this environment to an appropriate region based means to improve the communication with registries. Another application using the services is the transfer of data between two registries with common patients.

Integration of medical applications: the 'mediator service' of the SynEx platform.

Interoperability is a key issue and a long-term domain of research for distributed healthcare information systems. The SynEx European project provides open and standard integration platform for both new and legacy medical applications. It aims to provide access to hospital information services, patient records, and to medical knowledge, in a seamless way, hiding the distribution aspects and the heterogeneity of the underlying systems. In this study, we describe the SynEx 'mediator service', a software engineering component, that is used to facilitate the development of mediators between any pair of SynEx components and to manage the corresponding interchange messages. Both a C++ library and a Java package of a generic mediator model are provided with several ready-to-use specialisations for well-defined use. The use of the XML technology as a powerful data interchange format and as an efficient data structure converter is proposed and discussed.

The "mediator service", a component to ease the integration of medical applications in the SynEx framework.

Interoperability is a key issue and a long-term domain of research for distributed healthcare information systems. The European project SynEx provides an open and standard integration platform for both new and legacy medical applications. It allows the collaboration of distributed and heterogeneous healthcare records and services. It aims to provide access to Hospital Information Services, to remote sources of medical data and to medical knowledge, in a seamless way, hiding the distribution aspects and the heterogeneity of systems. In this project, the Medical Informatics Department of the Broussais University Hospital is responsible for the development of the "Mediator Service". It is a software component of the SynEx platform which is used as a "glue" mechanism to provide a flexible way to facilitate the interchange between any pair of systems, with different nomenclatures and data structures. The Mediator Service uses a generic model of mediators to create, through specialization, specific mediators for practical cases. Based on this model, it offers a C++ library to be used as the tool case by the programmers, to reduce the development effort. The use of XML as a powerful data interchange format and as a data structure descriptor is proposed and evaluated.

Standards for medical device communication: X73 PoC-MDC.

When using a number of medical devices from very different manufacturers with different proprietary formats the problem of a lack of interoperability emerges. Connectivity and communications are then limited and the systems and users can not exploit all the possibilities that Information and Communication Technologies offer today. The use and application of standards can be the solution to bring light to this confusion of languages in this Tower of Babel. There are several standards applicable to medical information systems interoperability and, analyzing these different options, the X73 PoC-MDC (ISO11073/IEEE1073) set of standards for Point of Care Medical Device Communication is the best positioned international standard to provide interoperability in these communications.
