Approaches to patient health information exchange and their impact on emergency medicine.

Regional health information organizations and electronic health information exchange may have an important impact on the practice of emergency medicine in the United States. Regional health information organizations are local or regional information-sharing networks that enable electronic data interchange among stakeholders in a given geographic area. These stakeholders may include hospitals, skilled nursing facilities, clinics, private physicians' offices, pharmacies, laboratories, radiology facilities, health departments, payers, and possibly the patients themselves. Regional health information organizations are being formed across the country to improve the safety and efficiency of clinical care; improve public health efforts, biosurveillance, and disaster management response; and potentially create large databases of deidentified aggregate data for research. Because of the unique need for rapid access to information and the acuity of the clinical environment, few areas of the health care delivery system stand to change and benefit more from health information exchange than our nation's emergency departments. This article will explain the motivation for the development of regional health information organizations, identify some of the important issues in their formation, and discuss how their development might affect the practice of emergency medicine.

SignalML: metaformat for description of biomedical time series.

This paper introduces a complete and elegant solution to the problem of inherent incompatibility of different formats used for digital storage of biomedical time series (in particular EEG) and their annotations. We define a simple XML-based language, in which information on the structure of binary data files can be simply and efficiently coded. In most cases, description of an existing format takes relatively few lines of XML code. Once written, this information can be used by any software, which, owing to this meta-description, may read the original data files, thus eliminating the need for conversions and duplication of data. This proposition is hereby submitted to an open discussion within the community involved in relevant research, clinical and commercial applications. Links to the current version of the XML Schema defining the language and pilot implementation of a compliant viewer/annotator are located at http://eeg.pl/SignalML/.

Advantages of combined touch screen technology and text hyperlink for the pathology grossing manual: a simple approach to access instructive information in biohazardous environments.

Gross examination, encompassing description, dissection, and sampling, is a complex task and an essential component of surgical pathology. Because of the complexity of the task, standardized protocols to guide the gross examination often become a bulky manual that is difficult to use. This problem is further compounded by the high specimen volume and biohazardous nature of the task. As a result, such a manual is often underused, leading to errors that are potentially harmful and time consuming to correct-a common chronic problem affecting many pathology laboratories. To combat this problem, we have developed a simple method that incorporates complex text and graphic information of a typical procedure manual and yet allows easy access to any intended instructive information in the manual. The method uses the Object-Linking-and-Embedding function of Microsoft Word (Microsoft, Redmond, WA) to establish hyperlinks among different contents, and then it uses the touch screen technology to facilitate navigation through the manual on a computer screen installed at the cutting bench with no need for a physical keyboard or a mouse. It takes less than 4 seconds to reach any intended information in the manual by 3 to 4 touches on the screen. A 3-year follow-up study shows that this method has increased use of the manual and has improved the quality of gross examination. The method is simple and can be easily tailored to different formats of instructive information, allowing flexible organization, easy access, and quick navigation. Increased compliance to instructive information reduces errors at the grossing bench and improves work efficiency.

A vocabulary development and visualization tool based on natural language processing and the mining of textual patient reports.

Medical terminologies are critical for automated healthcare systems. Some terminologies, such as the UMLS and SNOMED are comprehensive, whereas others specialize in limited domains (i.e., BIRADS) or are developed for specific applications. An important feature of a terminology is comprehensive coverage of relevant clinical terms and ease of use by users, which include computerized applications. We have developed a method for facilitating vocabulary development and maintenance that is based on utilization of natural language processing to mine large collections of clinical reports in order to obtain information on terminology as expressed by physicians. Once the reports are processed and the terms structured and collected into an XML representational schema, it is possible to determine information about terms, such as frequency of occurrence, compositionality, relations to other terms (such as modifiers), and correspondence to a controlled vocabulary. This paper describes the method and discusses how it can be used as a tool to help vocabulary builders navigate through the terms physicians use, visualize their relations to other terms via a flexible viewer, and determine their correspondence to a controlled vocabulary.

Using genomics to help predict drug interactions.

This article proposes using genomic information to help tailor the output of a drug interaction program for a patient. This paper focuses on a particular CYP450 enzyme to illustrate adding genomic information to an existing drug interaction database. The data are formatted as an Extensible Markup Language (XML) document. The additional interaction information based on genomics for a patient is added to an XML document using XML tags. The suggestion is to combine specifics about a patient's genome with genomic information in the drug interactions database to increase the accuracy and details of a drug interaction program.

Identification of national trends in nursing education through the use of an online survey.

Increased access and familiarity with computer technology has enhanced research data collection and analysis processes. Use of the Internet in these processes is rapidly becoming an alternative to traditional paper and pencil methods and can be a useful tool in conducting nursing education research. The purpose of this article is to discuss the use of online survey methodologies to identify nursing education trends and disseminate information nationwide. Advantages, disadvantages and pitfalls of using e-mail in conducting a Web-based survey are presented. The authors describe relevant aspects of developing and implementing an online survey; relate their experience in using this survey method with regard to its strengths and limitations; and, comment regarding efficacy of electronic collection and analysis of research data. The authors' experience in conducting a previously published national study of the integration of holistic nursing practices and complementary and alternative modalities in curricula of baccalaureate and higher degree schools of nursing is used as an exemplar. The authors conclude that, regardless of the current status of technology and lack of computer support in some schools of nursing, an online national survey is a valuable tool in conducting research in nursing education and increasingly will be the method of choice for gathering survey data.

CellML: its future, present and past.

Advances in biotechnology and experimental techniques have lead to the elucidation of vast amounts of biological data. Mathematical models provide a method of analysing this data; however, there are two issues that need to be addressed: (1) the need for standards for defining cell models so they can, for example, be exchanged across the World Wide Web, and also read into simulation software in a consistent format and (2) eliminating the errors which arise with the current method of model publication. CellML has evolved to meet these needs of the modelling community. CellML is a free, open-source, eXtensible markup language based standard for defining mathematical models of cellular function. In this paper we summarise the structure of CellML, its current applications (including biological pathway and electrophysiological models), and its future development--in particular, the development of toolsets and the integration of ontologies.

Evolution of web site design: implications for medical education on the Internet.

Since its inception, the world wide web (WWW) has possessed the potential for becoming a 'watershed' medium for conveying complex, structured information across vast temporal and geographical barriers. In 1995, the MedWorld project (http:(/)/medworld.stanford.edu) was created at the Stanford University School of Medicine in an effort to innovate and explore the design process of creating WWW applications specifically for medical education. Until recently, the evolution of WWW applications has been mainly driven by technological advances in client-server technology, enabling or translating traditional modes of collaborative medical education (e.g. voice, presence, print, motion) into WWW devices and applications. Many of these applications, while technologically advanced, lack focused development of interface and interactivity design, which may enhance learning experiences. WWW applications which incorporate design innovation in parity with advances in client-server technology have been termed, 'third generation' web sites and have the potential to improve the quality of WWW applications designed for medical education. This work describes how the MedWorld project has created a 'third generation' WWW application by utilizing innovation in information, interface and interactivity design to create innovative WWW technology for the medical education arena.

IDEM: a Web application of case-based reasoning in histopathology.

Different software engineering and artificial intelligence methods can be used to design Internet retrieval of prototypical medical images. We used the case-based reasoning (CBR) approach to provide an 'intelligent' access to a collection of illustrated medical cases through the Internet. This paper presents a Web interface for the CBR system IDEM (image and diagnosis from examples in medicine) in the domain of breast pathology. Thanks to the definition of a similarity measure between the descriptions of cases we propose a flexible querying of the case-base and a quantitative browsing among cases through similarity links. The resemblance rates provided by the system argue for the quality and the relevancy of the retrieved data. The flexibility of the querying process is robust to missing information and could be adapted to a daily practice. The CBR approach is a promising method for a clinical relevant and an efficient retrieval of reference images and diagnosis clues through Internet.

The telemedicine information exchange: an online resource.

Telemedicine is the use of telecommunications to provide health care services at a distance. It has grown from mostly government-subsidized research initiatives into a fledgling industry. This growth was fueled by decreasing costs of telecommunications and information technologies and fanned by rising health care costs. The telemedicine information exchange (TIE) (http:(/)/tie.telemed.org), developed by the Telemedicine Research Center in Portland, OR, is both a product and a vehicle of this rapid growth. It facilitates collection of telemedicine information from many sources, providing an easy-to-use hypertext format. This article describes the TIE's development, advantages and disadvantages of a web-based online library, and it's codevelopment with a rapidly expanding industry.

Modeling and implementing a database on drugs into a hospital intranet.

Our objective was to develop a drug information service, implementing a database on drugs in our university hospitals information system. Thériaque is a database, maintained by a group of pharmacists and physicians, on all the drugs available in France. Before its implementation we modeled its content (chemical classes, active components, excipients, indications, contra-indications, side effects, and so on) according to an object-oriented method. Then we designed HTML pages whose appearance translates the structure of classes of objects of the model. Fields in pages are dynamically fulfilled by the results of queries to a relational database in which information on drugs is stored. This allowed a fast implementation and did not imply to port a client application on the thousands of workstations over the network. The interface provides end-users with an easy-to-use and natural way to access information related to drugs in an internet environment.

Internet integrated in the daily medical practice within an electronic patient record.

Healthcare enters the information age and professionals are finding an ever-growing role for computers in the daily practice of medicine. However, a number of problematic issues are associated with electronic publications, especially through Internet. Whilst access to any information has been improved, access to specific information has become more and more difficult [1], due to the lack of a general meta-knowledge allowing to structure Internet resources. Physicians have to learn and adapt themselves to computers and Internet, but Internet has to meet the specific requirements of Healthcare. Important issues must therefore be addressed to allow a real and daily use of Internet in the medical practice. The paper discusses most of these issues and proposes a solution developed at the University Hospital of Geneva that integrates an Electronic Patient Record with Internet, without compromises on security or on performances and that runs on standard PCs'.

Usage analysis of a primary care medical resource on the Internet.

Physicians and patients need convenient access to quality medical information. This study's goal was to place a medical resource on the World-Wide Web (WWW), allow access to it through a simple to use interface, and analyze the usage of such a resource. The Family Practice Handbook (TFPH) was digitized and placed onto the WWW. Usage data was obtained from June 1995-June 1996. 118,804 individuals accessed TFPH viewing 409,711 pages of information. A broad spectrum of topics was accessed. TFPH proved to be an extremely popular resource, servicing the broad information needs of an international audience. These preliminary findings suggest the future promise of Internet medical resources.

Organizational considerations for an electronic curriculum. Part I: A rational nosology for concept management in dentistry.

STATEMENT OF PROBLEM: With the use of multimedia electronic knowledge as a tool in dental education, an overriding concern has centered on how to devise an organizational model that will accommodate the vast and diverse arrays of information involved, yet be sufficiently simple enough to provide students with a rational and consistent means of accessing the information they require. By adopting the natural history of the diseases dentists are called on to address as a common organizing principle, it becomes possible to link all concepts that relate to individual problem areas through a technique of retro-mapping. PURPOSE: The purpose of this article is to introduce learners to a cognitive "scaffolding" that will assist them in achieving a deeper cognitive dimension for problem solving.

Organising access to Evidence-Based Medicine resources on the Web.

The continuing education is a challenge for health care professionals, considering the growing amount and variable quality of information in this field. In this context, we developed a method allowing clinicians to have a centralised access to the best current medical evidence supporting medical decision-making. Relevant data has been gathered according to the rules stated for Evidence-Based Medicine (EBM) and organised in a free-of-charge Web site, created by using common software applications. The general aim of our study was to encourage individual practice of EBM by providing tutorials as well as a selection of free access tools for searching medical information on the Web. In addition to the education part, we provided clinicians, through a Web interface, with up-to-date, accurate and quality data obtained from heterogeneous sources and presented in a full text format when available. The developed methodology has been applied to human prostate cancer. URL address: http://www.ebm.lib.ulg.ac.be/prostate/index.htm.
