Health services, coordination and the Internet.

The on-going specialization of medical services requires socioeconomic coordination of different health services. The GP is the key to improve this primary coordination. To qualify referral decisions by the GP an Internet-like information system (VisInfo) has been implemented in Denmark. This VisInfo contains information on (1) alternative periods of waiting, (2) medical guidelines for specific treatments (3) clinical home pages, and (4) links to non-medical providers of health services (NGOs). VisInfo was originally implemented in the Counties of Funen, Northern Jutland and Vejle in 1993-1995. A number of other counties are implementing similar information systems whereof the County of Frederiksborg, recently has implemented the first real Internet-system. Provisional experiences with the VisInfo strategy is presented on (1) the general user interest, (2) elaborations of the strategy, and (3) organization. Based on the BlackSeaDiab Action Plan and the BlackSea TeleDiab project, the potential for dissemination of medical informatics in the Black Sea Region through an adaption of the VisInfo strategy is discussed.

An interactive multimedia training system for advanced cardiac life support.

This paper describes an Advanced cardiac life support (ACLS) training system (ACLSYS) with multimedia and hypertext features for training medical personnel and evaluating their performance during ACLS events. ACLSYS runs in a Windows 95 environment and is written in Visual Basic 4.0 Enterprise Edition and Access 7.0. The system consists of two primary modules: a multimedia training module and a simulation/evaluation module. The training module provides the knowledge and skills required for the appropriate early treatment of cardiopulmonary arrest. The simulation/evaluation module generates randomly an unlimited number of ACLS cases. These cases become part of the training case database and are available for retraining. ACLS certified personnel were included in the validation of the system.

A World Wide Web-based user interface for a data management system for use in multi-institutional clinical trials--development and experimental operation of an automated patient registration and random allocation system.

We have employed the Hypertext Transfer Protocol (HTTP) and Hypertext Markup Language (HTML) to develop an automated patient registration and random allocation system for use in a multi-institutional clinical trial. We made it available on-line to World Wide Web clients in each hospital through a user friendly graphical user interface. During experimental operation, the physicians found it satisfactory from the viewpoint of both ease of operation and response time. For the development of a graphical user interface in network-based information system for use in multi-institutional clinical trials, HTTP/HTML has several advantages over an ordinary client-server model. Therefore, we concluded that we would adopt HTP/HTML for the construction of user interfaces for physicians in each spital and for data managers in our coordinating center.

Patient information systems that tailor to the individual.

The potential of computers in patient education has been well described by Skinner et al. One of their recommendations was for more personalized systems. In this article we discuss how computer-based patient information systems can provide material that is tailored to the individual, giving a number of examples of systems developed in Scotland. We review some of the techniques used in developing tailored systems, and consider the evidence to date as to their efficacy.

Interactive health communication in preventive medicine: internet-based strategies in teaching and research.

Interactive health communication using Internet technologies is expanding the range and flexibility of intervention and teaching options available in preventive medicine and the health sciences. Advantages of interactive health communication include the enhanced convenience, novelty, and appeal of computer-mediated communication; its flexibility and interactivity; and automated processing. We outline some of these fundamental aspects of computer-mediated communication as it applies to preventive medicine. Further, a number of key pathways of information technology evolution are creating new opportunities for the delivery of professional education in preventive medicine and other health domains, as well as for delivering automated, self-instructional health behavior-change programs through the Internet. We briefly describe several of these key evolutionary pathways. We describe some examples from work we have done in Australia. These demonstrate how we have creatively responded to the challenges of these new "information environments," and how they may be pursued in the education of preventive medicine and other health care practitioners and in the development and delivery of health behavior-change programs through the Internet. Innovative and thoughtful applications of this new technology can increase the consistency, reliability, and quality of information delivered.

Computer expert system for the histopathologic diagnosis of salivary gland neoplasms.

The design, development, and testing of a prototype interactive histopathologic expert system capable of diagnosing 15 types of primary salivary gland neoplasms is described. The system incorporates a multiple subprogram modular design and makes use of multiple reasoning methods including: data-driven and goal-directed rule-based reasoning, linear pattern recognition, and Bayesian classification. Its user interface incorporates both a "hypertext" context-sensitive information assistance facility and the video display of stored and digitized photomicrographic images. The system can report a differential diagnosis of its findings with assessment of its confidence in its diagnosis. The system's performance was evaluated in a series of tests. The results of a weighted kappa analysis of the system's diagnoses versus those of four oral pathologists for 20 salivary gland neoplasms indicated no statistical difference in diagnostic performance between the system and the human experts and each of the experts in relationship to the others (Wilcoxon rank sums test). A modified version of Turing's test of artificial intelligence demonstrated no statistically significant difference in the system's diagnoses versus the diagnosis of four human expert pathologists (Fisher's exact test). The knowledge and experience gained in the development and testing of the expert system described in this study have demonstrated the validity of histopathologic diagnostic expert systems in a selected area of oral pathology.

A network of web multimedia medical information servers for a medical school and university hospital.

Modern medicine requires a rapid access to information including clinical data from medical records, bibliographic databases, knowledge bases and nomenclature databases. This is especially true for University Hospitals and Medical Schools for training as well as for fundamental and clinical research for diagnosis and therapeutic purposes. This implies the development of local, national and international cooperation which can be enhanced via the use and access to computer networks such as Internet. The development of professional cooperative networks goes with the development of the telecommunication and computer networks and our project is to make these new tools and technologies accessible to the medical students both during the teaching time in Medical School and during the training periods at the University Hospital. We have developed a local area network which communicates between the School of Medicine and the Hospital which takes advantage of the new Web client-server technology both internally (Intranet) and externally by access to the National Research Network (RENATER in France) connected to the Internet network. The address of our public web server is http:(/)/www.med.univ-rennesl.fr.

Exchanging clinical knowledge via Internet.

The need for effective and efficient exchange of clinical knowledge is increasing. Paper based methods for managing clinical knowledge are not meeting the demand for knowledge and this has undoubtedly contributed to the widely reported failures of clinical guidelines. Internet affords both opportunities and dangers for clinical knowledge. Systems such as Wax have demonstrated the importance of intuitive structure in the management of knowledge. We report on a new initiative for the global management of clinical knowledge.

An intranet database for pacemaker patients.

A database system, incorporating smartcard technologies, was designed to hold the personal and pacing details of pacemaker patients, who attended a clinic at the Royal Sussex County Hospital (RSCH), Brighton, UK. Following an initial period of a 12 month clinical trial, with the database running on a standalone personal computer, the Pacemaker Patient Database has been redesigned and implemented as an intranet-based system. This paper describes the issues relating to the development of the new prototype system and identifies the design principles for intranet-based electronic health care (EHCR) record database systems.

Computer assisted medical diagnosis using the Web.

The ADM (Aide au diagnostic Medical) project was started 15 years ago and was the first telematic project for physicians in France using the MINITEL terminal. The knowledge base contains information on more than 10000 diseases from all pathological fields, using more than 100000 signs or symptoms. The ADM system has two main functionalities for physicians: consultation of diseases descriptions and list of diseases containing one or more symptoms. The ADM knowledge base is supported by a relational database management system (DBMS ORACLE) and we developed a Web interface using the Perl language to produce HTML pages for the web server. We will describe our experience on redesigning a large existing medical knowledge base for diffusion on the web Internet.

The Internet and randomised controlled trials.

Several factors constrain the implementation of Randomised Controlled Trials (RCTs). To obtain large sample sizes a multicentred multinational trial may be necessary or a long sampling period. The larger the trial the larger is the unit cost. To allow larger sample sizes, shorter sampling periods and lower unit costs, new methods are needed. The Internet and in particular the WWW provides such an opportunity. The WWW can provide global access, fast interaction and automation. A prototype Internet Trials Service (ITS) is currently being tested with a real international clinical trial (the Growth Restriction Intervention Trial--GRIT). The ITS is hosted on a Web server. It provides a series of HTML documents that describe the GRIT protocol. Registered centres may enter patients into the GRIT trial via ITS. Java applets are used to collect trial data before returning the study number and randomisation. ITS assumes all trial data will be intercepted by a sniffer. Therefore no information is sent that could specifically identify a patient, this must be sent later by more secure means. ITS assumes that trial centres can be spoofed. To authenticate the patients entered into the trial and the trial data sent, a regular audit report is sent to each centre by secure means for confirmation. By using Java, a full functional data entry system can be developed that runs locally within any Java enabled browser. It can perform data validation locally and also provide a sophisticated user interface.

Information retrieval: an overview of system characteristics.

The paper gives an overview of characteristics of information retrieval (IR) systems. The characteristics are identified from the descriptions of 23 IR systems. Four IR models are discussed: the Boolean model, the vector model, the probabilistic model and the connectionistic model. Twelve other characteristics of IR models are identified: search intermediary, domain knowledge, relevance feedback, natural language interface, graphical query language, conceptual queries, full-text IR, field searching, fuzzy queries, hypertext integration, machine learning, and ranked output. Finally, the relevance of IR systems for the World Wide Web is established.

CARDIOMEDIA: a communicable multimedia medical record on Intranet and digital optical memory card.

As part of French health reform, French physicians were computerised by the end of 1998. A specific Intranet network will be used to communicate medical data between the health professionals. The objectives of the CARDIOMEDIA project were to develop and evaluate the feasibility of a coronary multimedia data record stored on an optical card and communicable on Intranet within the hospital. Patients treated by angioplasty at the University Hospital of Rennes participated in the experiment. In general, patients are treated in the University Hospital and are followed up by another health care provider closer to their home. The patient leaves the University Hospital with his card, which is directly available elsewhere for emergency or for consultation. This approach is assumed to reduce the number of examinations and to offer a better patient follow-up. The CARDIOMEDIA card is a specialised record including various data types: text, images, image sequences of coronarography and ECG signals. For this purpose an optical card with its large memory is very convenient. We used the DICOM format for image exchange and management. It is combined with CARDIOMEDIA specific compressing software. For the multimedia record the HTML format and web Intranet method are chosen. This provides an intuitive interface which can combine various data types and helper applications like a DICOM image viewer.

Medical markup language (MML) for XML-based hospital information interchange.

Medical Markup Language (MML) has been developed over the last 6 years in order to create a set of standards by which medical data, within Japan and hopefully worldwide, can be stored, accessed and exchanged in any number of physical locates. The MML version 2.21 is characterized by XML as meta-language, module structure for each document and enhancement of linking function among documents. Data exchange specification has been also added for query and reply. MML instances are composed of MML header and MML body. The MML header includes information for data transmission, while MML body includes several module items. One module item contains two elements: document information and module content. Nine MML module contents are defined at the present time: patient information, health insurance information, diagnosis information, lifestyle information, basic clinic information, particular information at the time of first visit, progress course information, surgery record information and clinical summary information.
