Nurses' requirements for information technology in the next millennium.

The main purpose of this study was to identify nurses' requirements for information technology in the next millennium. We distributed 350 questionnaires in a teaching hospital in Brazil and in the USA. We received 86 from Brazil and 78 from USA. Besides the capabilities of computers to be used in different sectors of human actions, nurses' requirements for information technology can not be considered sophisticated. Nurses in Brazil prefer a standalone system. In contrast, in USA they prefer systems that could be integrated to the whole healthcare system. Also, in the USA, nurses were more comfortable with use of computers than nurses in Brazil. In general terms, nurses in both countries feel that computer systems could make their practice easier and more efficient.

Outreach to public health professionals: lessons learned from a collaborative Iowa public health project.

In 1995, the National Library of Medicine (NLM) and the Public Health Service (PHS) recommended that special attention be given to the information needs of unaffiliated public health professionals. In response, the National Network of Libraries of Medicine (NN/LM) Greater Midwest Region initiated a collaborative outreach program for public health professionals working in rural east and central Iowa. Five public health agencies were provided equipment, training, and support for accessing the Internet. Key factors in the success of this project were: (1) the role of collaborating agencies in the implementation and ongoing success of information access outreach projects; (2) knowledge of the socio-cultural factors that influence the information-seeking habits of project participants (public health professionals); and (3) management of changing or varying technological infrastructures. Working with their funding, personnel from federal, state, and local governments enhanced the information-seeking skills of public health professionals in rural eastern and central Iowa communities.

Health telematics applications and user acceptance from a medical student's point of view.

The goal of the workshop is dual. The first is to convince health care professionals of health telematics applications' usefulness by demonstrating convincing cases and the second is to examine the practical side of the story which is education and training in health telematics. The purpose of this paper is to present the way health telematics appeal to a medical student. After all it's the medical student and the young practitioner whose lifetime practice will depend on the health telematics applications that are today under development.

Utilization of information technology in medical education: a questionnaire survey of students in a Malaysian institution.

OBJECTIVE: The objective of this survey was to obtain a self-reported assessment of the use of Information and Communication Technology (ICT) by medical students at the International Medical University, Malaysia. MATERIALS AND METHODS: Students' perceived skills and extent of usage of ICT were evaluated using a questionnaire. Chi-square analysis were performed to ascertain the association between variables. Further statistical testing using Chi-square test for trend was done when one of the variables was ordered, and Spearman rank correlation when both variables were ordered. RESULTS: Overall, (98%) of students responded to the questionnaire. Twenty seven students (5.7%) did not use a computer either in the university or at home. Most students surveyed reported adequate skills at word processing (55%), e-mailing (78%) and surfing the internet (67%). CONCLUSION: The results suggests that in order to increase the level of computer literacy among medical students, positive steps would need to be taken, for example the formal inclusion of ICT instruction in the teaching of undergraduate medicine. This will enhance medical students' ability to acquire, appraise, and use information in order to solve clinical and other problems quickly and efficiently in the course of their studies, and more importantly when they graduate.

[Implementation of mutual information based medical image registration methods].

Image registration methods based on mutual information, including mutual information and normalized mutual information, have been accepted as the most accurate and efficient methods. But there are many fluctuations in the registration functions that hinder the optimization procedure and lead to registration failure in intra-modal registration. We found that besides the interpolation artifacts, the uncertainty of the changing of entropy with the changing of overlap also contributes to the fluctuations. The effect of interpolation artifacts can be eliminated, but it is difficult to eliminate the effect of uncertainty of entropy. Luckily, this effect is not significant in normalized mutual information. Normalized mutual information is more stable and robust than standard mutual information and its better performance and wider application can be expected.

Accurate searching using XML and topic maps.

Most clinical data is narrative text and often not accessible and searchable at the clinical workstation. We have therefore developed a search engine that allows indexing, searching and linking different kinds of data using web technologies. Text matching methods fail to represent implicit relationships between data, e.g. the relationship between HIV and AIDS. The ISO topic maps standard provides a data model that allows representing arbitrary relationships between resources. Such relationships form the basis for context sensitive searching and accurate search results. XML standards are used for the interchange of data relationships. Our approach has been applied to medical classification systems and clinical practice guidelines with promising results.

Informatics Workup.

We introduce the concept of a Medical Informatics Workup performed by fourth year medical students working in a busy inner-city Emergency Room. These students use portable computers (Macintosh PowerBook 170s connected to a removable cartridge hard drive and CD-ROM drive) to do the patient workups. The PowerBook 170 contains the automated medical record entry software (IMR-E), five expert system software packages, and a program that allows the PowerBook to emulate a PC-compatible computer. With this configuration the student has a portable system that allows for the creation of a computerized medical record at the patient's bedside, along with the ability to analyze the data and generate a list of differential diagnoses.

Java-based Open Platform for distributed health telematics applications.

Within the European HARP project, a Java-based Open Platform has been specified and implemented to support trustworthy distributed applications for health. Emphasis was put on security services for enabling both communication and application security. The Open Platform is Web-based and comprises the Client environment, Web/Application server, as well as Database and Archive servers. Servlets composed and executed according to the user's authorisation create signed XML messages. From those messages, user-role-related applets are generated. The technical details of the realisation are presented. Possible future enhancements for user-centric, adaptable services based on next-generation mobile service environments are outlined.

Public key infrastructures for health.

Introducing the technological step into this new 3rd millennium, advanced communication means like global networks including the Internet become more and more important for a fast and convenient information exchange across regional and even national borders. Concerning the sector of public and private healthcare and welfare, new health information system, or citizens' information systems in general, are coming up to meet the needs of the whole information society. Thus, developing and implementing those systems is one of the most important aims of the present and the near future. Access to, and communication of, relevant patient-related administrative and medical information items always means a secure and trustworthy way of dealing with data. Concerning the main aspects of specific legal, social, ethical, technical, organisational, and even political requirements for secure access and secure communication of health data in terms of data protection, data security, privacy, safety and quality using unprotected networks as, e.g., the Internet, there is a strong and even growing need for the fundamental technology of Trusted Third Parties to meet the whole range of the security categories as integrity, confidentiality, availability, accountability, and access control.
