Telemedicine and medical informatics in the multimedia super corridor: the Malaysian vision.

The practice of medicine, with its wide range of environmental conditions and complex dependencies, has long been used as a test bed for various advanced technologies. Telemedicine, as conceptualised within the Multimedia Super Corridor (MSC) context, is seen as the application of several relatively mature technologiesartificial intelligence (AI), multimedia communication and information systems (IS) amongst othersso as to benefit a large cross-section of the Malaysian population. We will discuss in general terms the Malaysian vision on the comprehensive MSC telemedicine solution, its functionality and associated operational conditions. In particular, this paper focuses on the conceptualisation of one key telemedical component i.e. the Lifetime Health Plan (LHP) system, which is eventually intended to be a distributed multi-module application for the periodic monitoring and generation of health-care advisories for upwards of 20 million Malaysians.

The structure of medical informatics journal literature.

OBJECTIVE: Medical informatics is an emergent interdisciplinary field described as drawing upon and contributing to both the health sciences and information sciences. The authors elucidate the disciplinary nature and internal structure of the field. DESIGN: To better understand the field's disciplinary nature, the authors examine the intercitation relationships of its journal literature. To determine its internal structure, they examined its journal cocitation patterns. MEASUREMENTS: The authors used data from the Science Citation Index (SCI) and Social Science Citation Index (SSCI) to perform intercitation studies among productive journal titles, and software routines from SPSS to perform multivariate data analyses on cocitation data for proposed core journals. RESULTS: Intercitation network analysis suggests that a core literature exists, one mark of a separate discipline. Multivariate analyses of cocitation data suggest that major focus areas within the field include biomedical engineering, biomedical computing, decision support, and education. The interpretable dimensions of multidimensional scaling maps differed for the SCI and SSCI data sets. Strong links to information science literature were not found. CONCLUSION: The authors saw indications of a core literature and of several major research fronts. The field appears to be viewed differently by authors writing in journals indexed by SCI from those writing in journals indexed by SSCI, with more emphasis placed on computers and engineering versus decision making by the former and more emphasis on theory versus application (clinical practice) by the latter.

A national agenda for public health informatics: summarized recommendations from the 2001 AMIA Spring Congress.

The AMIA 2001 Spring Congress brought together members of the the public health and informatics communities to develop a national agenda for public health informatics. Discussions of funding and governance; architecture and infrastructure; standards and vocabulary; research, evaluation, and best practices; privacy, confidentiality, and security; and training and workforce resulted in 74 recommendations with two key themes-that all stakeholders need to be engaged in coordinated activities related to public health information architecture, standards, confidentiality, best practices, and research; and that informatics training is needed throughout the public health workforce. Implementation of this consensus agenda will help promote progress in the application of information technology to improve public health.

[HL7 standard--features, principles, and methodology].

The mission of HL7 Inc. non-profit organization is to provide standards for the exchange, management and integration of data that support clinical patient care, and the management, delivery and evaluation of healthcare services. As the standards developed by HL7 Inc. represent the world's most influential standardization efforts in the field of medical informatics, the HL7 family of standards has been recognized by the technical and scientific community as the foundation for the next generation healthcare information systems. Versions 1 and 2 of HL7 standard have solved many issues, but also demonstrated the size and complexity of health information sharing problem. As the solution complete new methodology has been adopted that is encompassed in the HL7 Version 3 recommendations. This approach standardizes Reference Information Model (RIM), which is the source of all derived domain models and message structures. Message design is now defined in detail, enabling interoperability between loosely coupled systems that are.designed by different vendors and deployed in various environments. At the start of the Primary Healthcare Information System project in the Republic of Croatia in 2002, the decision was to go directly to Version 3. The target scope of work includes clinical, financial and administrative data management in the domain of healthcare processes. By using HL7v3 standardized methodology we were able to completely map the Croatian primary healthcare domain to HL7v3 artefacts. Further refinement processes that are planned for the future will provide semantic interoperability and detailed description of all elements in HL7 messages. Our HL7 Business Component is in constant process of studying different legacy applications, making solid foundation for their integration to HL7-enabled communication environment.

Testing the knowledge of postgraduate trainees in medicine: a multimedia software package.

1. TASK OF THE PROGRAM. The task of the program is to test the knowledge of applicants at the examination for specialists degrees. The applicants must answer a series of multiple choice test questions, 40% of them are connected to a medical diagnostic image of different modalities e.g., x-ray, 2D gray scale ultrasound, CT, MRI, and endoscopy images. The answer may need simple measurements and finding target areas on the image. The program manages to: test 20 applicants simultaneously in a network, handle a database of questions and images, and document and print out exam results. 2. ORGANIZATIONAL ENVIRONMENT OF THE PROGRAM. The program was developed at the Medical Informatics Department of "Haynal Imre" University of Health Sciences, Budapest (MID-HIETE) according to the needs and intentions of the National Board of Medical Postgraduate Training. The program was sponsored by the OMFB/National Committee of Technical Development, a government agency, and by one of the commercial banks. 3. TECHNICAL ENVIRONMENT OF THE PROGRAM. 4. SCIENTIFIC BASIS. The data bank was developed according to a previous study of medical images in clinical practice. The study describes the information content of different medical images and their role in medical practice. The image data bank originates from the developer's own medical image library and from internationally acknowledged medical textbooks (respecting copyright issues). Knowledge base of questions was drawn from basic international textbooks. 5. SUMMARY. Within a period of two years, the MID-HIETE staff succeeded in developing a modular multimedia software package that tests and screens the knowledge of postgraduate trainees. This screening method is offered as an entrance exam for the specialist degree. Currently, this exam is administered as an oral test; the knowledge of the applicants may therefore not be tested thoroughly.

Managing change: an overview.

As increasingly powerful informatics systems are designed, developed, and implemented, they inevitably affect larger, more heterogeneous groups of people and more organizational areas. In turn, the major challenges to system success are often more behavioral than technical. Successfully introducing such systems into complex health care organizations requires an effective blend of good technical and good organizational skills. People who have low psychological ownership in a system and who vigorously resist its implementation can bring a "technically best" system to its knees. However, effective leadership can sharply reduce the behavioral resistance to change-including to new technologies-to achieve a more rapid and productive introduction of informatics technology. This paper looks at four major areas-why information system failures occur, the core theories supporting change management, the practical applications of change management, and the change management efforts in informatics.

Generic design of Web-based clinical databases.

BACKGROUND: The complexity and the rapid evolution and expansion of the domain of clinical information make development and maintenance of clinical databases difficult. Whenever new data types are introduced or existing types are modified in a conventional relational database system, the physical design of the database must be changed accordingly. For this reason, it is desirable that a clinical database be flexible and allow for modifications and for addition of new types of data without having to change the physical database schema. The ideal clinical database would therefore implement a highly-detailed logical database schema in a completely-generic physical schema that stores the wide variety of clinical data in a small and constant number of tables. OBJECTIVE: The objective was to review the medical literature regarding generic design of clinical databases. METHODS: A search strategy was devised for PubMed and Google to get the best match of peer-reviewed articles and free Web resources on the subject. RESULTS: Eight peer reviewed articles and a Web tutorial were found. All the resources described the so-called Entity-Attribute-Value (EAV) design as a means of simplifying the physical layout of data tables in a clinical database. In Entity-Attribute-Value design all data can be stored in a single generic table with conceptually 3 columns: 1 for entity (eg, patient identification), 1 for attribute (eg, name), and 1 for value (eg, "Jens Hansen"). To add more descriptive fields to the entity class, all that is necessary is to add attribute values to be stored in the attribute field. The main advantages of the Entity-Attribute-Value design are flexibility and effective entity-centered data retrieval. The main disadvantages are complicated front-end programming needed to display data in a conventional layout that the user understands and less-efficient attribute-centered queries. The Internet offers unique opportunities for database deployment, eliminating problems of user-interface deployment. Furthermore, Web forms may be generated in a completely-generic fashion during run time from metadata describing the semantic structure of clinical information stored in the database. CONCLUSIONS: The Entity-Attribute-Value model is useful for generic design of clinical databases. Depending on the specific requirements of the application, more or less complex metadata models may be applied.

ICT in health care: sociotechnical approaches.

The importance of the social sciences for medical informatics is increasingly recognized. As ICT requires inter-action with people and thereby inevitably affects them, understanding ICT requires a focus on the interrelation between technology and its social environment. Sociotechnical approaches increase our understanding of how ICT applications are developed, introduced and become a part of social practices. Socio-technical approaches share several starting points: 1) they see health care work as a social, 'real life' phenomenon, which may seem 'messy' at first, but which is guided by a practical rationality that can only be overlooked at a high price (i.e. failed systems). 2) They see technological innovation as a social process, in which organizations are deeply affected. 3) Through in-depth, formative evaluation, they can help improve system design and implementation.

Medical informatics in the medical curriculum--when?

Undergraduate teaching of medical informatics (MI) at the Medical School University of Zagreb has been changing its position in the medical curriculum. Nowadays, this subject is positioned in the second year of the medical curriculum. The aim of this paper is to find out what the students of the second year (S2Y) and of the sixth year (S6Y) think about the position of MI in the medical curriculum. The results of students' opinions have shown that MI should be positioned: in the last two years (63% of S2Y, 36% of S6Y), in the middle (11% of S2Y, 21% of S6Y), and at the beginning of the medical curriculum (26% of S2Y, 43% of S6Y). However, analysing this question according to previous experience of the students of both groups, it can be concluded that: the S6Y with more previous experience shift the subject towards the end of the medical curriculum, and the S2Y with more previous experience shift the subject towards the beginning of the medical curriculum. According to our long-term experience and students' opinion, the most relevant MI subjects, any kind of medical application, should necessarily come at the end of the medical curriculum.

Using the UMLS Semantic Network as a basis for constructing a terminological knowledge base: a preliminary report.

Sharing and reuse of knowledge bases is recognized in Artificial Intelligence and Medical Informatics as beneficial, but difficult. Reusing an existing knowledge base can save considerable time and effort during the knowledge engineering phase, and facilitates integration of systems. However, the degree to which knowledge can be shared among different applications is still mainly an empirical question. In this paper, we describe the preliminary results of our attempt to reuse the UMLS Semantic Network as an ontology for the knowledge base of a patient education system.

Curriculum for building medical resources on the Internet--experience in Taiwan.

This paper describes our experience with a one-semester course on how to build a medically-related homepage on the Internet, designed for fourth-year medical students. Based on the assumption of limited technical knowledge of the Internet, this class taught students Internet-exploring skills, multimedia authoring and HTML (Hypertext Markup Language) in the first eight-week period. Students were then divided into four-person teams and asked to select a topic for a homepage. These teams were then asked to collect the necessary resources for the development of the homepage both through individual work and, consultation with an advisor. Each group project for building medically-related homepage was accomplished and presented in the remaining four-week period. The resultant projects of these fourth-year medical students were of surprisingly good content and high quality. Medical students rapidly learned to use the software tools, and through proper instruction and provision of equipment, they were able to build significant medical resources on the Internet that can potentially be useful in education, clinical applications and research.

Dimensions of time in illness: an objective view.

It is almost impossible to try to represent and analyze clinical data in the absence of a temporal dimension. The temporal aspect is especially important when automated decision support is used for patient care over substantial periods. This paper emphasizes the crucial role that tasks of temporal reasoning and temporal maintenance play in modern medical information and decision support systems; it also discusses the implications of providing automated support to clinicians who must perform such tasks as part of broader clinical tasks (for example, monitoring and therapy). Temporal reasoning tasks mainly involve intelligent analysis of time-oriented clinical data, and temporal maintenance tasks focus on effective storage and retrieval of these data. Both types of tasks, however, are highly relevant for such applications as patient monitoring, proper use of therapeutic guidelines, assessment of the quality of guideline use, and visualization and exploration of time-oriented biomedical data. Scientists in medical informatics should view the integration of these two areas as a major research and development goal. This paper demonstrates one approach to integration by presenting the concept of a temporal mediator, which combines temporal reasoning and temporal maintenance. Use of the temporal mediator in several clinical tasks is also presented and discussed.
