Since progress during the early stages of a program cannot easily be measured in terms of the ultimate objectives, there is need to develop a set of intermediate indicators for purposes of necessary evaluation and monitoring. Family planning programs suggest a series of useful intermediate objectives that have a clear cause-and-effect relationship with regard to their ultimate goals. It is important that they be expressed as specific targets. They should provide for a numerical definition of the target population; a given time frame; a service design which takes into account patient load, personnel performance, and service capacities; and a record system that can readily retrieve information about service utilization and also identify each patient individually. At the same time, allowance should be made for periodic review and adjustments in light of modifications that are bound to occur in the composition of the target population as well as possible changes of a sociopolitical nature that might affect the program's scope.
Classification in psychiatry serves as a basis for communication within science, as a basis of information retrieval, as a descriptive system, as a source for the construction of theories, and finally as a basis for making predictions. Not only has research diagnostic criteria had significant importance to research, but they can now serve the clinician equally well as exemplified by DSM III.
The INFORMM NIS (Information Network For Online Retrieval & Medical Management Nursing Information System) provides on-line documentation of patient care orders. These orders, generated by the nurse or the physician, prescribe direct patient care and do not include interdepartmental orders such as laboratory, radiology, or pharmacy. The order charting functions support charting efficiency by defaulting previous responses so that the user enters only updates to earlier findings or new data. Available in tables maintained by NIS staff, charting responses provide decision support by suggesting valid results for each order. Using point-of-care devices, nursing staff chart patient data that are immediately available for review by all authorized members of the health care team. These data are printed automatically on computer-generated chart forms every twenty-four hours, but may be printed also on demand. Additionally, the patient data report, containing patient data entered on-line in the sixteen or twenty-four hours immediately preceding the print request, provides a summary that is useful for nurses' report and physicians' rounds.
This paper focuses on the visual interface for image retrieval from radiology image database and describes a Radiologic Pictionary. A Radiologic Pictionary is a picture-based controlled vocabulary that allows visual query formulation by providing the user with images (samplers) that are linked to the hierarchical index of radiological findings and mapped into image data within the database. Samplers selected during query formulation point to image records that share their characteristics; all matching images are returned to the user.
Because clinical databases vary in structure, access methods and vocabulary used to represent data, the Arden Syntax does not define a standard model for querying databases. Consequently, database queries are encoded in ad hoc ways and enclosed in "curly braces" in Medical Logic Modules (MLMs). However, the nonstandard representation of queries impairs sharing of MLMs, an impediment that has come to be known as the "curly braces problem." As a first step in solving this problem, we evaluated the proposed HL7 Reference Information Model (RIM) as a foundation for a standard query model for the Arden Syntax. Specifically, we analyzed the MLM knowledge base at the Columbia-Presbyterian Medical Center and compared the queries in these MLMs to the RIM. We studied 488 queries in 104 MLMs, identifying 674 total query data elements. Laboratory tests accounted for 45.8% of these elements, while demographic and ADT data accounted for 37.6%. Pharmacy orders accounted for 10.5%, medical problems for 4.3% and MLM output messages for 1.6%. We found that the RIM encompasses all but those data elements signifying MLM output (1.6% of the total). We conclude that the majority of queries in the CPMC knowledge base access a relatively small set of data elements and that the RIM encompasses these elements. We propose extensions of this analysis to continue construction of an Arden query model capable of solving the "curly braces problem."
Integrating functions from disparate and widely-distributed information systems has been an interest of the medical informatics community for some time. Barriers to progress have included the lack of network-accessible information sources, inadequate methods for inter-system messaging, and lack of vocabulary translation services. With the advent of the World Wide Web (WWW) and the evolution of the National Library of Medicine's Unified Medical Language System (UMLS), it is now possible to develop applications that integrate functions from diverse, distributed systems. In this paper we describe one such system, MedWeaver, a WWW application that integrates functions from a decision support application (DXplain), a literature searching system (WebMedline), and a clinical Web searching system (CliniWeb) using the UMLS Metathesaurus for vocabulary translation. This system demonstrates how application developers can design systems around anticipated clinical information needs and then draw together the needed content and functionality from diverse sources.
In order to take full advantage of computer-based decision support in clinical practice, it makes sense to combine systems which support the same subject, but contribute to this task in different ways. At the Technical University of Munich, a Combined Clinical Decision Support System (C-CDSS) of this kind has been designed for gastroenterologists. The main goal of the system is to help the physicians in finding information which is relevant for making the right diagnoses or applying the proper therapy to his patients. To achieve this goal, not only systematic knowledge of the medical domain, but also case-based data is useful for a comparison of the actual case with well-documented similar cases of colleagues. The systematic knowledge comprises state-of-the-art textual information and selected multimedia contents in the sense of a standard textbook. The case-based information includes practice-related information on a pool of anonymized cases from clinical routine and also demonstrations of new techniques. By integrating these information resources into one service via a rule-based retrieval system, a powerful decision support system can be generated.
Primary goals are to enable practitioners to use the Web to manage computer-based patient records, facilitating input and updating, not just retrieval and review. Early adopters are tackling a host of complex technical and operational issues.
The "evidence-based medicine" (EBM) paradigm is centered on the concept of "best evidence" and clinical studies based on this approach are more likely to be considered by physicians in their practice. In this paper we describe an ontology representing the concepts involved in evidence-based medicine and meta-analysis and show how an ontological approach can be applied both for revisiting EBM conceptual foundations and for allowing a more effective knowledge-based information retrieval in literature.
The introduction of computers in the medical environment has contributed to the proliferation of medical data, often making it difficult to consolidate information on a single patient. In patients with complex medical problems, such as oncology patients, the lack of data integration can negatively impact on patient care. This paper presents an infrastructure for the creation of an integrated multimedia timeline that automatically combines patient information from distributed hospital information sources, and creates a visual summary of pertinent events in a patient's medical history. In this prototype, we focus on oncology patients under treatment for advanced cancers.
The Veterinary Biologics Information System is a project the main goal of which is to collect, analyze and manage data concerning registered veterinary biologics and biotechnological products employed to control animal diseases by the countries of the Americas. Data from each country was gathered by cataloguing each biological product on a questionnaire form. The collected data was then fed into an electronic data base system. A retrieval program was subsequently developed, allowing the user quick access to all data stored in the system. The system operates in English and Spanish and includes such information as the product name, registration number, ingredients, species for which the product is approved for use, the disease against which the product is used, names of manufacturers and distributors and other distinguishing characteristics of the product including expiry dates and withdrawal times. This computerized system, with on-line data bases which can be quickly updated, provides a dynamic answer to the question of timely information concerning veterinary biological products.
Concept Locator (CL) is a client-server application that accesses a Sybase relational database server containing a subset of the UMLS Metathesaurus for the purpose of retrieval of concepts corresponding to one or more query expressions supplied to it. CL's query grammar permits complex Boolean expressions, wildcard patterns, and parenthesized (nested) subexpressions. CL translates the query expressions supplied to it into one or more SQL statements that actually perform the retrieval. The generated SQL is optimized by the client to take advantage of the strengths of the server's query optimizer, and sidesteps its weaknesses, so that execution is reasonably efficient.
This paper introduces the active index for content-based medical image retrieval. The dynamic nature of the active index is its most important characteristic. With an active index, we can effectively and efficiently handle smart images that respond to accessing, probing and other actions. The main applications of the active index are to prefetch image and multimedia data, and to facilitate similarity retrieval. The experimental active index system is described.
This paper describes the joint efforts of the Cleveland Poison Information Center and the Cleveland Health Sciences Library to develop a workable system for scanning the current journal literature for relevant articles on the therapy of poisonings and to develop a suitable system for reorganizing the present reprint files for the city's two units of the Poison Information Center. The use of the MEDLINE computer retrieval system for retrieving relevant current articles is discussed in detail as is the proposed reorganization of the Center's reprint file.
