Anatomically flexible, computer-assisted reporting system for coronary angiography.

A computer-assisted method for reporting coronary arteriographic findings has been developed. A videographic display with a touch input system permits finger pointing to designate arterial segments, lesion locations, graft insertion points and collateral vessels. The coronary diagram is flexible to accommodate variations in dominance and in the size and length of the left coronary system branches. Lesion severity, type and length of lesions, distal vessel anatomy, collateral circulation and coronary bypass grafts (including Y or jump grafts) are displayed pictographically. A tabular summary and graphic output provide a completed coronary report eliminating the need for narrative dictation. An edit mode provides capability for teaching and review. The computer-assisted reporting method has the advantage of automatic data encoding in formats suitable for data base storage and subsequent retrieval.

Ontology development for a pharmacogenetics knowledge base.

Research directed toward discovering how genetic factors influence a patient's response to drugs requires coordination of data produced from laboratory experiments, computational methods, and clinical studies. A public repository of pharmacogenetic data should accelerate progress in the field of pharmacogenetics by organizing and disseminating public datasets. We are developing a pharmacogenetics knowledge base (PharmGKB) to support the storage and retrieval of both experimental data and conceptual knowledge. PharmGKB is an Internet-based resource that integrates complex biological, pharmacological, and clinical data in such a way that researchers can submit their data and users can retrieve information to investigate genotype-phenotype correlations. Successful management of the names, meaning, and organization of concepts used within the system is crucial. We have selected a frame-based knowledge-representation system for development of an ontology of concepts and relationships that represent the domain and that permit storage of experimental data. Preliminary experience shows that the ontology we have developed for gene-sequence data allows us to accept, store, and query data submissions.

A Canadian nursing minimum data set: a major priority.

Through a selected review of existing hospital and health care minimum data sets in the United States, the United Kingdom and Canada, the authors expose the nursing data gaps in those data sets. Nurses in the United States have responded to these data gaps through the development of a Nursing Minimum Data Set (NMDS). The NMDS is a tool for abstracting a uniform collection of essential nursing data from the patient record usually at hospital discharge. The nursing care data elements in the NMDS include: nursing diagnosis, nursing intervention, nursing outcome, and intensity of nursing care. A major factor influencing the move to generate an NMDS in Canada is the response to the need to contain rising health care costs while maintaining quality health care. The NMDS has profound implications for nurses in all practice settings through use of these data in: costing of nursing services; defending resource allocation to nursing; defining nursing's contribution to patient care; defining outcomes of nursing care; developing nursing knowledge; and continued growth of nursing as a profession. Initiatives in Canada directed at the development of an NMDS indicate a heightened awareness of the need for the collection, storage and retrieval of nursing data. However, nurses in Canada have yet to define the essential nursing data elements for inclusion in a national health information system for use in Canada.

[Demographic statistics after the GBA Law is passed].

"The Dutch Ministry of Internal Affairs plans to replace the old written population systems on paper with a new system of decentralized automated population registers (in Dutch this system is called: GBA) on 1 October 1994.... In the summer of 1993 Statistics Netherlands carried out a test to find out whether the GBA messages are appropriate for making population statistics. To do this such messages were forwarded to Statistics Netherlands by five municipalities for three months. The conclusion of the test results was that the GBA system is technically adequate for making population statistics." (SUMMARY IN ENG)

Opportunities for and challenges of computerisation.

Information technology offers many potential advantages over paper for the storage and retrieval of patients' data. Enthusiasts predict that soon all records will be stored and viewed on computer, but others are more sceptical. The failure of some computer-based records may be due to poor information design. This paper explores how computers broaden the range of design options but points out that more attention to design is required for computer-based than for paper-based records.

Prototype implementation of the integrated genomic database.

We aim to develop an open software system to handle human genome data. The system, called Integrated Genomic Database (IGD), will integrate information from many genomic databases and experimental resources into a comprehensive target-end database (IGD TED). Users will access front-end client systems (IGD FRED) to download data of interest to their computers and merge them with their own local data. FREDs will provide persistent storage of, and instant access to, retrieved data; a friendly graphical interface; tools for querying, browsing, analyzing, and editing local data; interface to external analysis; and tools for communicating with the outside world. The TED will be accessible over the network (online and offline) as a read-only resource for multiple clients. It collects data from major databases for nucleotide and protein sequences and structures, genome maps, experimental reagents, phenotypes, and bibliographic data, and sets of raw data produced at genome centers and laboratories. Beside character-based access via Gopher, WAIS, FTP, and several query language interfaces to the TED, we will develop a specialized front-end client, IGD FRED, with its own database manager, based on the ACEDB program. The FRED will support graphical display methods for sequence feature maps, chromosomal genetic and physical maps, and experimental objects like clone grids, etc. FRED will also provide an interface to important analysis software packages and tools for submitting data to external databases in their own format.

Research data integrity: a result of an integrated information system.

The toxicologic problems of today frequently require long-term, multidisciplinary experimentation involving large numbers of animals. In order to provide the extensive safety evaluation necessary to produce data that can be reasonably extrapolated to humans, automated research support systems have transcended the position of useful tools and have become an integral part of the total design of experimental protocols. For an automated information system to fully represent the reality of the experiment, it must be able to assure integrity, as well as provide for the storage, calculation, and retrieval of data values of the quality and quantity necessary for fulfilling protocol requirements. Guarantees against error and loss of data, in addition to flexibility and easy access, must be an inherent part of the system if the acceptance and condifence of the investigator are to be obtained. This paper discusses the criteria, philosophies, and benefits of integrated data systems that ensure integrity of toxicologic research support.

Effective coding in birth defects surveillance.

Effective coding is critical to data collected by birth defects surveillance programs because subsequent use of the data depends on storage and retrieval of cases using codes. Hence, careful consideration needs to be given to the coding process. The primary goal of coding is to accurately, completely, and concisely represent infants with birth defects. Coding procedures need to accommodate the objectives of the surveillance program; for example, programs that focus on research may require different coding procedures from those that focus on linking infants to services. Several challenges exist in coding birth defects, including the need to distinguish infants with multiple defects and syndromes from those with isolated defects, and the need for strategies to code suspected defects for which confirmation is not available. Selection of a coding system by a birth defects surveillance program is central to the utility of the data collected. Most programs use a modification of the International Statistical Classification of Diseases and Related Health Problems-based (ICD) systems. This paper addresses ICD-based systems and the modifications used by many birth defects surveillance programs and presents examples of the problems in interpreting birth defects data because of inappropriate coding.

Information systems in food safety management.

Information systems are concerned with data capture, storage, analysis and retrieval. In the context of food safety management they are vital to assist decision making in a short time frame, potentially allowing decisions to be made and practices to be actioned in real time. Databases with information on microorganisms pertinent to the identification of foodborne pathogens, response of microbial populations to the environment and characteristics of foods and processing conditions are the cornerstone of food safety management systems. Such databases find application in: Identifying pathogens in food at the genus or species level using applied systematics in automated ways. Identifying pathogens below the species level by molecular subtyping, an approach successfully applied in epidemiological investigations of foodborne disease and the basis for national surveillance programs. Predictive modelling software, such as the Pathogen Modeling Program and Growth Predictor (that took over the main functions of Food Micromodel) the raw data of which were combined as the genesis of an international web based searchable database (ComBase). Expert systems combining databases on microbial characteristics, food composition and processing information with the resulting "pattern match" indicating problems that may arise from changes in product formulation or processing conditions. Computer software packages to aid the practical application of HACCP and risk assessment and decision trees to bring logical sequences to establishing and modifying food safety management practices. In addition there are many other uses of information systems that benefit food safety more globally, including: Rapid dissemination of information on foodborne disease outbreaks via websites or list servers carrying commentary from many sources, including the press and interest groups, on the reasons for and consequences of foodborne disease incidents. Active surveillance networks allowing rapid dissemination of molecular subtyping information between public health agencies to detect foodborne outbreaks and limit the spread of human disease. Traceability of individual animals or crops from (or before) conception or germination to the consumer as an integral part of food supply chain management. Provision of high quality, online educational packages to food industry personnel otherwise precluded from access to such courses.
