Overcoming information overload: an information system for the primary care physician.

Primary Care Office InSite (PCOI) is a Web-based intranet application that provides ready access to a collection of information useful in primary care. The PCOI Web site was developed by, and is widely used within, the Massachusetts General Hospital (MGH) and its affiliated community practices. Over 1600 users logged 60,000 separate sessions in the past year. The site contains clinical practice guidelines, patient educational material, drug prescription and cost information and referral information, all designed for use during routine patient care activity. A continuing and dynamic collaboration between the users and developers of the system, just-in-time access and a "one-stop portal" to a variety of resources have resulted in a very high approval rating by the users. This paper discusses the important characteristics of the Web site, specific functions that improve the workflow of the practicing clinician, and limitations of the present implementation.

An Internet-based approach to advising radiology residency applicants.

RATIONALE AND OBJECTIVES: The authors created a computerized database Web site enabling radiology residency applicants to utilize the experience of recent graduates from their school in maximizing the effectiveness of the residency advisory process. Objectives of this database Web site are (a) to provide general information regarding radiology as a specialty; (b) to allow students to gauge their chances of matching based on the experience of recent graduates from their school; (c) to provide advisors with a faster, more accurate assessment of a student's matching potential; and (d) to decrease the number of residency applications submitted through the Electronic Residency Application Service. MATERIALS AND METHODS: Thirty graduates from the University of Medicine and Dentistry of New Jersey-Robert Wood Johnson Medical School (UMDNJ-RWJMS) from 1999 to 2001 who applied to radiology residency were successfully contacted by telephone or e-mail. Data were gathered regarding their academic performance and activities, residency application, and final match outcome and were entered into a spreadsheet for analysis. This information, along with student-to-student advice regarding the match, was also entered into an interactive Web site for use by UMDNJ-RWJMS medical students, radiology advisors, and deans. RESULTS: The Web site model was applied to radiology residency applicants from UMDNJ-RWJMS. This database Web site provided general radiology information and allowed students and advisors to gauge their chances of matching based on the experience of past applicants from their school. CONCLUSION: This database Web site can provide a realistic comparison of a student's academics with those of previous applicants. Yearly analysis of school-specific data can help advisors follow applicant trends and modify their own advice. The database Web site can be easily duplicated and, if applied to other schools and specialties, could potentially benefit students nationally.

Challenges in implementing a knowledge editor for the Arden Syntax: knowledge base maintenance and standardization of database linkages.

CONTEXT: Incorporation of research findings into clinical practice lags behind their dissemination in the medical literature. Arden Syntax is a standard that could be used to encode evidence in a clinical decision support system (CDSS). However, dissemination of knowledge is hampered by lack of standard linkages to clinical databases. OBJECTIVE: To create a knowledge editor that facilitates transfer of knowledge from the medical literature to clinical practice via a CDSS. METHODS: Using a Web browser-based application, we implemented linkages to MEDLINE to permit queries on demand and registration of queries to be executed periodically, with results copied into Arden Medical Logic Modules (MLMs). To facilitate standardization of MLMs, database linkages are encoded using emerging HL7 standards such as a data model (virtual medical record). CONCLUSIONS: A Web-based application can facilitate transfer of knowledge into clinical practice and knowledge base maintenance through periodic queries and deployment of standards for knowledge representation.

Technical development of PubMed interact: an improved interface for MEDLINE/PubMed searches.

BACKGROUND: The project aims to create an alternative search interface for MEDLINE/PubMed that may provide assistance to the novice user and added convenience to the advanced user. An earlier version of the project was the 'Slider Interface for MEDLINE/PubMed searches' (SLIM) which provided JavaScript slider bars to control search parameters. In this new version, recent developments in Web-based technologies were implemented. These changes may prove to be even more valuable in enhancing user interactivity through client-side manipulation and management of results. RESULTS: PubMed Interact is a Web-based MEDLINE/PubMed search application built with HTML, JavaScript and PHP. It is implemented on a Windows Server 2003 with Apache 2.0.52, PHP 4.4.1 and MySQL 4.1.18. PHP scripts provide the backend engine that connects with E-Utilities and parses XML files. JavaScript manages client-side functionalities and converts Web pages into interactive platforms using dynamic HTML (DHTML), Document Object Model (DOM) tree manipulation and Ajax methods. With PubMed Interact, users can limit searches with JavaScript slider bars, preview result counts, delete citations from the list, display and add related articles and create relevance lists. Many interactive features occur at client-side, which allow instant feedback without reloading or refreshing the page resulting in a more efficient user experience. CONCLUSION: PubMed Interact is a highly interactive Web-based search application for MEDLINE/PubMed that explores recent trends in Web technologies like DOM tree manipulation and Ajax. It may become a valuable technical development for online medical search applications.

A patterned approach for linking knowledge-based systems to external resources.

Knowledge-based systems (KBSs) have been developed and used in industry and government as assistance systems, voting partner systems, and embedded applications. As web-based systems change the face of software implementations, these closed, internal KBSs need to be integrated into multicomponent applications that provide updated and extensible services. Therefore, KBSs must be adapted to an environment in which data and control are exchanged with external processes and resources; complementing other participating systems or using them to refine its own results. This integration can be a daunting task. If improperly done, it can result in an inefficient and unmanageable composite application. One approach to simplifying this task is the use of architectural patterns for integration. These patterns are assembled from functional entities that resolve component interoperability conflicts. In this paper, we describe an architectural pattern called the Knowledge Director pattern, which directs the integration of a closed KBS into a broader application environment.

Deltarho-web, an online tool to assess composition similarity of individual nucleic acid sequences.

SUMMARY: Although whole-genome sequences have been analysed for the presence of anomalous DNA, no dedicated application is currently available to analyse the composition of individual sequence entries, for instance those derived by experimental techniques, such as subtractive hybridization. Since genomic dinucleotide frequency values are conserved between related species, a representative genome sequence can often be found to score for anomalous sequence composition for many of these putative horizontally transferred sequences. We developed the application deltarho-web, which enables the determination of the differences between the dinucleotide composition of an input sequence and that of a selected genome in a size-dependent manner. A feature allowing batch comparisons is included as well. In addition, deltarho-web allows the analysis of the dinucleotide composition of complete genomes. This provides complementary information for the identification of large anomalous gene clusters.

MIPS Arabidopsis thaliana Database (MAtDB): an integrated biological knowledge resource for plant genomics.

Arabidopsis thaliana is the most widely studied model plant. Functional genomics is intensively underway in many laboratories worldwide. Beyond the basic annotation of the primary sequence data, the annotated genetic elements of Arabidopsis must be linked to diverse biological data and higher order information such as metabolic or regulatory pathways. The MIPS Arabidopsis thaliana database MAtDB aims to provide a comprehensive resource for Arabidopsis as a genome model that serves as a primary reference for research in plants and is suitable for transfer of knowledge to other plants, especially crops. The genome sequence as a common backbone serves as a scaffold for the integration of data, while, in a complementary effort, these data are enhanced through the application of state-of-the-art bioinformatics tools. This information is visualized on a genome-wide and a gene-by-gene basis with access both for web users and applications. This report updates the information given in a previous report and provides an outlook on further developments. The MAtDB web interface can be accessed at http://mips.gsf.de/proj/thal/db.

Web-building time in a spider: preliminary applications of ultrasonic detection.

Data collection on time and length of building in orb-weaving spiders has suffered from absence of light during construction and inconvenient hours. A simple apparatus is described which permits recording of the spiders' movements as they disturb an ultrasonic field. By varying onset and length of dark periods for two animals at even temperature and by registering the building periods for 127 webs, a definite influence of the light-dark cycle can be identified: there is a strong preference for building webs in the dark; this is superimposed on the circadian rhythm of orb-web construction. One of the spiders always built earlier than the other.

Does foraging adaptation create the positive complexity-stability relationship in realistic food-web structure?

The adaptive food-web hypothesis suggests that an adaptive foraging switch inverses the classically negative complexity-stability relationships of food webs into positive ones, providing a possible resolution for the long-standing paradox of how populations persist in a complex natural food web. However, its applicability to natural ecosystems has been questioned, because the positive relationship does not emerge when a niche model, a realistic "benchmark" of food-web models, is used. I hypothesize that, in the niche model, increasing connectance influences the fraction of basal species to destabilize the system and this masks the inversion of the negative complexity-stability relationship in the presence of adaptive foraging. A model analysis shows that, if this confounding effect is eliminated, then, even in a niche model, a population is more likely to persist in a more complex food web. This result supports the robustness of adaptive food-web hypothesis and reveals the condition in which the hypothesis should be tested.

Adapting EcoCyc for use on the World Wide Web.

The World Wide Web (WWW) offers the potential to deliver specialized information to an audience of unprecedented size. Along with this exciting new opportunity comes a challenge for software developers: instead of rewriting our software applications to operate over the WWW, how can we maximize software reuse by retrofitting existing applications? We have developed a Web server tool, written in Common Lisp, that allows existing graphical user interface applications written using the Common Lisp Interface Manager (CLIM) to hook easily into the WWW. This tool-CWEST (CLIM-WEb Server Tool, pronounced "quest")-was developed to operate with EcoCyc, an electronic encyclopedia of the genes and metabolism of the bacterium E. coli. EcoCyc consists of a database of objects relevant to E. coli biochemistry and a user interface, implemented in CLIM, that runs on the X-window system and generates graphical displays appropriate to biological objects. Each query to the EcoCyc WWW server is treated as a command to the EcoCyc program, which dynamically generates an appropriate CLIM drawing. CWEST translates that drawing, which can be a mixture of text and graphics, into the HyperText Markup Language (HTML) and/or the Graphics Interchange Format (GIF), which are returned to the client. Sensitive regions embedded in the CLIM drawing are converted to hyperlinks with Universal Resource Locators (URLs) that generate further EcoCyc queries. This tight coupling of CLIM output with Web output makes CLIM a powerful high-level programming tool for Web applications. The flexibility of Common Lisp and CLIM made implementation of the server tool surprisingly easy, requiring few changes to the existing EcoCyc program. The results can be seen at URL http: @www.ai.sri.com/ecocyc/browser.html. We have made CWEST available to the CLIM community at large, with the hope that it will spur other software developers to make their CLIM applications available over the WWW.

The wireless Web and patient care.

Wireless computing, when integrated with the Web, is poised to revolutionize the practice and teaching of medicine. As vendors introduce wireless Web technologies in the medical community that have been used successfully in the business and consumer markets, clinicians can expect profound increases in the amount of patient data, as well as the ease with which those data are acquired, analyzed, and disseminated. The enabling technologies involved in this transformation to the wireless Web range from the new generation of wireless PDAs, eBooks, and wireless data acquisition peripherals to new wireless network protocols. The rate-limiting step in the application of this technology in medicine is not technology per se but rather how quickly clinicians and their patients come to accept and appreciate the benefits and limitations of the application of wireless Web technology.

Design considerations in migrating an obstetrics clinical record to the Web.

Recently the American College of Obstetricians and Gynecologists (ACOG) embarked on an effort to promote the development of nationally networked obstetrical records. The Laboratory of Computer Science (LCS) is collaborating with them to help achieve this goal through the development of a web-based prototype of an electronic medical record (EMR) which would allow the entry and display of typical clinical information for the obstetric patient. The process of porting a stand alone application to the web environment necessitated the development of a robust software scheme that could exploit the strengths of Web-based technologies and avoid some of the drawbacks inherent in a stateless environment.

Information technology in nursing: a project examining educational applications of the Internet and World Wide Web.

Developments in Information Technology are requiring nurses to not only access complex information but also manipulate it within an information rich environment to benefit patient care. Within such an environment, the role played by the Internet and more specifically, the World Wide Web (WWW or web), will become increasingly important to health care providers. Nurse academics within the School of Nursing, Monash University, have adopted an innovative and integrated approach to Internet technologies as part of information processing and inquiry in nursing. This approach is aimed at enhancing the teaching/learning process by lending additional richness to the learning environment. Initial feedback from this project supports the assumption that information technology has an important, and increasingly prominent, role to play within nursing education and clinical practice. Although very much at an embryonic stage, the project has been well received by students and staff alike. This descriptive paper will attempt to highlight some of the benefits of the project for nurse academics and students, provide an overview of Internet and WWW applications and suggest some practical applications of these technologies in nurse education.

Using web technology and Java mobile software agents to manage outside referrals.

A prototype, web-based referral application was created with the objective of providing outside primary care providers (PCP's) the means to refer patients to the Massachusetts General Hospital and the Brigham and Women's Hospital. The application was designed to achieve the two primary objectives of providing the consultant with enough data to make decisions even at the initial visit, and providing the PCP with a prompt response from the consultant. The system uses a web browser/server to initiate the referral and Java mobile software agents to support the workflow of the referral. This combination provides a light client implementation that can run on a wide variety of hardware and software platforms found in the office of the PCP. The implementation can guarantee a high degree of security for the computer of the PCP. Agents can be adapted to support the wide variety of data types that may be used in referral transactions, including reports with complex presentation needs and scanned (faxed) images Agents can be delivered to the PCP as running applications that can perform ongoing queries and alerts at the office of the PCP. Finally, the agent architecture is designed to scale in a natural and seamless manner for unforeseen future needs.
