Realization of a CPR using HL7 queries from communication server to information server.
A communication server is often used in Germany to interface legacy systems. It handles the translation, duplication, and transmission of messages to all systems that might need this information. Based on the principles of "for every data there is only one master" and "information on demand" we have built an information server that reduces the messages required and simplifies the handling of messages, the update of data already sent compared to a communication server. It also allows to implement a security policy as required by the German data privacy legislature.

The use of a standardized terminology for comparison of free text and structured data entry.
The Minimal Standard Terminology (MST) for gastrointestinal endoscopy, the product of an international effort, is to be been used in a study comparing free text to structured reports of esophagogastroduodenoscopies (EGDs). This requires some assumptions and adaptations in order to map to the MST in a uniform and quantifiable manner. Initial mapping has suggested a number of problem areas which require further investigation.

Clinical benchmarking enabled by the digital health record.
Office-based physicians are often ill equipped to report aggregate information about their patients and practice of medicine, since their practices have relied upon paper records for the management of clinical information. Physicians who do not have access to large-scale information technology support can now benefit from low-cost clinical documentation and reporting tools. We developed a hosted clinical data mart for users of a web-enabled charting tool, targeting the solo or small group practice. The system uses secure Java Server Pages with a dashboard-like menu to provide point-and-click access to simple reports such as case mix, medications, utilization, productivity, and patient demographics in its first release. The system automatically normalizes user-entered clinical terms to enhance the quality of structured data. Individual providers benefit from rapid patient identification for disease management, quality of care self-assessments, drug recalls, and compliance with clinical guidelines. The system provides knowledge integration by linking to trusted sources of online medical information in context. Information derived from the clinical record is clinically more accurate than billing data. Provider self-assessment and benchmarking empowers physicians, who may resent "being profiled" by external entities. In contrast to large-scale data warehouse projects, the current system delivers immediate value to individual physicians who choose an electronic clinical documentation tool.

Integration of Web-based and PC-based clinical research databases.
UNLABELLED: We have created a Web-based repository or data library of information about measurement instruments used in studies of multi-factorial geriatric health conditions (the Geriatrics Research Instrument Library - GRIL) based upon existing features of two separate clinical study data management systems. GRIL allows browsing, searching, and selecting measurement instruments based upon criteria such as keywords and areas of applicability. Measurement instruments selected can be printed and/or included in an automatically generated standalone microcomputer database application, which can be downloaded by investigators for use in data collection and data management. METHODS: Integration of database applications requires the creation of a common semantic model, and mapping from each system to this model. Various database schema conflicts at the table and attribute level must be identified and resolved prior to integration. Using a conflict taxonomy and a mapping schema facilitates this process. RESULTS: Critical conflicts at the table level that required resolution included name and relationship differences. CONCLUSIONS: A major benefit of integration efforts is the sharing of features and cross-fertilization of applications created for similar purposes in different operating environments. Integration of applications mandates some degree of metadata model unification.

MUDRLite - health record tailored to your particular needs.
Nowadays most hospitals use electronic health records as part of their hospital information systems. However, these systems are more suitable for hospital management than for physicians. The health record is not sufficiently structured; it includes a lot of free-text information, and the set of collected attributes is fixed and practically impossible to extend. Physicians, gathering information for the purpose of medical studies, often use varied proprietary solutions based on MS Access databases or MS Excel Sheets. The EuroMISE Centre - Cardio is developing an electronic health record (EHR) application called MUDRLite, which could easily fill the gap between existing EHRs. MUDRLite is the result of applied research in the field of EHR design, which is based on experience gathered during cooperation in the TripleC project. MUDRLite development is an extra branch in the MUDR (MUltimedia Distributed Record) development; it simplifies both the MUDR architecture and the MUDR data storage principles.MUDRLite itself is an empty body, which has to be filled in with an XML configuration file. This file completely describes the visual aspects and the behavior of the EHR application. It includes simple 4GL-like constructs written in the MUDRLite Language (MLL). This enables - using the event-oriented programming principles - to program various handling procedures for a range of actions, e.g. clicking a button fills a form with the result of an SQL statement. MUDRLite can be tailored to particular needs of any healthcare provider. This makes the MUDRLite application easy to use in specific environments. In the first instance, we are testing it at the Neurovascular Department of the Central Military Hospital in Prague.

[General principles of database storage operations with emphasis on OLAP reports].
In article general principles and features of data warehouse were presented in particular of OLAP reports. The data warehouse was built using Oracle tools. The repository was filled with death records from Central Office of Statistics. Various features adequate for epidemiological analyses have been discussed and illustrated like pivoting and rotating dimension, drilling on hierarchical data, reduction of dimensions. The possibility of specific for epidemiology indicators creation was shown. The need of implementation of data warehouses and OLAP reports in Polish healthcare was discussed. In comparison with traditional manner of analysis and presentation epidemiological facts OLAP reports give new perspectives.

[Problems of medical documentation in the hospital].
Problems of medical documentation arise from an explosive increase of data-volumes, complexity and multiplicity in data-management. The causality of that development, the possibility of computerized support in repetitive data-management, the economic, organizing and scientific problems are widely discussed. Solving the problems in the hospital a potent middle-ranged computer offers his services under certain circumstances. To obtain an efficient support following details are to take into consideration: reduction in manipulation-time, program-organization under medical demands, safe transfer of data and text by application of modern and potent database management systems as a tool of organizing, combining and retrieving informations.

Building a flexible protocol information system with ready for use' web-technology.
This paper describes how web technology, currently available, can be used to build a fast and easy flexible protocol information system. The interface design and functionalities of the system were based on experiences with a previous version of a protocol information system (ProtoVIEW). A wide range of diagnostic or therapeutic protocols could be retrieved and viewed with ProtoVIEW. The Web-based version contains all functionalities of the non web-based version plus several new functionalities. The web version contains an X-ray viewer and a great deal of interactivity such as validation of electronic patient data forms. The most important additional function is the context sensitive protocol support that may lead to improved protocol adherence. Finally, the web-based version can be accessed from any working place since patient data and protocols are stored centrally.

Searching for information on the Internet using the UMLS and Medical World Search.
Medical World Search is a search engine for medical information on the Internet that distinguishes itself from other search engines by its built-in knowledge of medical terminology through its use of the National Library of Medicine's UMLS and its carefully selected but large database of medical sites. After discussing some of the previous uses of the UMLS for medical information retrieval, we describe the Medical World Search system. In October 1996, Medical World Search became operational on the World Wide Web at http:@www.mwsearch.poly.edu. It has been operating uninterrupted since then. We review our experiences with creating a search engine for medical information on the Internet and using the UMLS in this application. The UMLS has some clear advantages in this application. Some aspects of the UMLS also decrease its usefulness in information retrieval. Medical World Search's usage by medical information seekers is summarized. future directions for research are outlined.

The management of information: storage and retrieval of data.
Internationally harmonized and cost-effective control of chemicals marketed worldwide greatly depend both on the generation of and easy access to reliable and comparable experimental information. Stored data are of use only if information can be retrieved quickly in an understandable form. Some models and theories of information retrieval (e.g. fuzzy set theory, probabilistic approach, artificial intelligence) are briefly discussed first, then followed by applications (such as indexing and clustering techniques). Finally the structure of databases is briefly reviewed.

[The computer assisted pacemaker clinic at the regional hospital of Udine (author's transl)].
For a close follow-up of large groups of pacemaker patients and for evaluation of long term pacing on a reliable statistical basis, many pacemaker centers in the world are now using computer systems. A patient data system with structured display records, designed to give complete, comprehensive and surveyable information and which are immediately retrievable 24 hours a day, on display or printed sets, seems to offer an ideal solution. The pacemaker clinic at the Regional Hospital of Udine has adopted this type of system. The clinic in linked to a live, on-line patient data system (G/3, Informatica Friuli-Venezia Giulia). The input and retrieval of information are made through a conventional keyboard. The input formats have fixed headings with coded alternatives and a limited space for comments in free text. The computer edits the coded information to surveyable reviews. Searches can be made on coded information and data of interest.

Gene Expression Dynamics Inspector (GEDI): for integrative analysis of expression profiles.
UNLABELLED: Genome-wide expression profiles contain global patterns that evade visual detection in current gene clustering analysis. Here, a Gene Expression Dynamics Inspector (GEDI) is described that uses self-organizing maps to translate high-dimensional expression profiles of time courses or sample classes into animated, coherent and robust mosaics images. GEDI facilitates identification of interesting patterns of molecular activity simultaneously across gene, time and sample space without prior assumption of any structure in the data, and then permits the user to retrieve genes of interest. Important changes in genome-wide activities may be quickly identified based on 'Gestalt' recognition and hence, GEDI may be especially useful for non-specialist end users, such as physicians. AVAILABILITY: GEDI v1.0 is written in Matlab, and binary Matlab.dll files which require Matlab to run can be downloaded for free by academic institutions at http://www.chip.org/~ge/gedihome.html SUPPLEMENTARY INFORMATION: http://www.chip.org/~ge/gedihome.html

Model storage, exchange and integration.
The field of Computational Systems Neurobiology is maturing quickly. If one wants it to fulfil its central role in the new Integrative Neurobiology, the reuse of quantitative models needs to be facilitated. The community has to develop standards and guidelines in order to maximise the diffusion of its scientific production, but also to render it more trustworthy. In the recent years, various projects tackled the problems of the syntax and semantics of quantitative models. More recently the international initiative BioModels.net launched three projects: (1) MIRIAM is a standard to curate and annotate models, in order to facilitate their reuse. (2) The Systems Biology Ontology is a set of controlled vocabularies aimed to be used in conjunction with models, in order to characterise their components. (3) BioModels Database is a resource that allows biologists to store, search and retrieve published mathematical models of biological interests. We expect that those resources, together with the use of formal languages such as SBML, will support the fruitful exchange and reuse of quantitative models.
