Empirical formulation of a generic query set for clinical information retrieval systems.

Information needs in clinical practice take the form of specific questions about a given clinical situation, and are best satisfied by concise and specific information retrieval. We sought to develop a comprehensive set of generic queries for information retrieval from electronic medical information resources. We collected one hundred and ten real-world questions asked at the point of care in a variety of settings, and from these developed a set of generic queries of which each of the real-world queries could be shown to be a special case. To provide allowed values for each of the concept terms in the queries, we defined generic nouns as unions of UMLS semantic types, and specified which of these were appropriate to each query. We have begun to use the set to index reference texts from general and subspecialty medicine, and found it capable of full text indexing in the clinical domain. We hypothesize that the query set can serve as a basis for more specialized query sets, and that it will remain generalizable to other electronic medical resources, indexing tasks, and non-UMLS controlled vocabularies.

Medicaid program; Medicaid management information system: revised definition of "mechanized claims processing and information retrieval system"--HCFA. Final rule with comment period.

We are making a number of revisions to regulations concerning mechanized claims processing and information retrieval systems ("system" or "systems"). We are revising definitions to show that we will not make available Federal funding at 75 and 90 percent of State Medicaid agency expenditures for eligibility determination systems because they do not meet the definition of a "mechanized claims processing and information retrieval system" or of an enhancement to that system. We are also conforming our regulations to changes made by section 9503(b)(2) and 9518 of the Consolidated Omnibus Budget Reconciliation Act (COBRA) of 1985 (Pub. L. 99-272), which involve technical changes. One change affects the frequency and scope of our system reviews, and the other involves the date by which States that are not exempt by law must have an operating system.

Evaluation of three manual drug information retrieval systems for investigational antineoplastic drugs.

The manual drug information retrieval systems, de Haen's Drugs in Use, Iowa Drug Information Service (IDIS), and International Pharmaceutical Abstracts (IPA), were evaluated to determine their usefulness as sources of drug information for investigational antineoplastic drugs during the years 1980-81. During both years, de Haen's provided the greatest number of antineoplastic drug citations, IPA the least. Concerning qualitative analysis, (the ability of the information systems to provide citations in seven subject areas for the five drugs), IDIS was found to have the greatest overall utility and was statistically different from IPA in many subject areas. IPA provided few citations in the seven subject areas for the five drugs. On pairwise analysis, no differences emerged between IDIS and de Haen's. Commonly available manual drug information retrieval systems such as IDIS and de Haen's appear to be useful sources of information for investigational antineoplastic drugs.

[Automated information retrieval system of the trauma physician].

The traumatologist's automatic information retrieval system (TAIRS) is a package of programmes and a database, which are implemented on the basis of informational models of mechanical and thermal injuries of the locomotor apparatus and hyperreactive adaptation syndromes in posttraumatic emergencies. TAIRS envisages operation in the following areas: 1) topometameric classification of locomotor mechanical injuries and recommendations on their treatment; 2) tabular models of hyperreactive adaptation syndromes and ways of their correction in posttraumatic emergencies; 3) terminological and eponymic glossaries.

[Experience using the automated information retrieval system "Biopsy" in the pathology department of a general hospital].

Automatic information retrieval system (AIRS) "Biopsy" has been created on the basis of original programs and personal computer and tested for 3 years in the activity of the pathology department of a big multidisciplinary hospital. AIRS considerably increases the level of the labour organization and facilitates the overall and routine analysis of both biopsy material and the work of a department.

Factors associated with successful answering of clinical questions using an information retrieval system.

OBJECTIVES: Despite the growing use of online databases by clinicians, there has been very little research documenting how effectively they are used. This study assessed the ability of medical and nurse-practitioner students to answer clinical questions using an information retrieval system. It also attempted to identify the demographic, experience, cognitive, personality, search mechanics, and user-satisfaction factors associated with successful use of a retrieval system. METHODS: Twenty-nine students completed questionnaires of clinical and computer experience as well as tests of cognitive abilities and personality type. They were then administered three clinical questions to answer in a medical library setting using the MEDLINE database and electronic and print full-text resources. RESULTS: Medical students were able to answer more questions correctly than nurse-practitioner students before and after searching, but both had comparable improvements in the number of correct questions before and after searching. Successful ability to answer questions was also associated with having experience in literature searching and higher standardized test-score percentiles. CONCLUSIONS: Medical and nurse-practitioner students obtained comparable benefits in the ability to answer clinical questions from use of the information retrieval system. Future research must examine strategies that improve successful search and retrieval of clinical questions posed by clinicians in practice.

[A data bank for the "Disaster Medicine" automated information retrieval system].

The article substantiate the necessity to improve the automatization of the information process in the system of medical support in extreme situations and thus to liquidate the disproportion between the medico-diagnostical and information accumulation storage facilities. These facts clearly define the importance of work which is being carried out by Medical Service towards an elaboration of the "Disaster Medicine" automated information retrieval system (AIRS). The data obtained as a result of AIRS processing could be directly used for reference or prediction purposes.

Evaluation of an information retrieval system for assessment of toxicological effects of chemicals on fish, wildlife, and ecosystem components.

A user-oriented information retrieval system is needed for assessment of materials hazardous to fish, wildlife, food chain organisms, and other organisms essential to the maintenance to ecosystem processes and functions. Critical evaluation of data also requires rigorous documentation of test conditions, precision of methods used, and the sensitivity of the test organism. Particular emphasis of the evaluation was in developing practical criteria that aid in the use and interpretation of data with respect to need for further testing in a scoring exercise performed for the Toxic Substances Control Act Interagency Testing Committee. Recommendations are made for the integration of information on physical and chemical properties, health effects, ecotoxicology, and environmental concentration or exposure level.

A Java-based multi-institutional medical information retrieval system.

JAMI (Java-based Agglutination of Medical Information) is designed as a framework for integrating heterogeneous information systems used in healthcare related institutions. It is one of the implementations under the W3-EMRS project 1 aimed at using the World Wide Web (Web) to unify different hospital information systems. JAMI inherited several design decisions from the first W3-EMRS implementation described in, including using the Web as the communication infrastructure and HL7 as the communication protocol between the heterogeneous systems and the W3-EMRS systems. In addition, JAMI incorporates the growing Java technologies and has a more flexible and efficient architecture. This paper describes JAMI's architecture and implementation. It also present two instances of JAMI, one for the integration of different hospital information systems and another for the integration of two heterogeneous systems within a single hospital. Some important issues for the further development of JAMI, including security and confidentiality, data input and decision support are discussed.

How well do physicians use electronic information retrieval systems? A framework for investigation and systematic review.

OBJECTIVE: Despite the proliferation of electronic information retrieval (IR) systems for physicians, their effectiveness has not been well assessed. The purpose of this review is to provide a conceptual framework and to apply the results of previous studies to this framework. DATA SOURCES: All sources of medical informatics and information science literature, including MEDLINE, along with bibliographies of textbooks in these areas, were searched from 1966 to January 1998. STUDY SELECTION: All articles presenting either classifications of evaluation studies or their results, with an emphasis on those studying use by physicians. DATA EXTRACTION: A framework for evaluation was developed, consisting of frequency of use, purpose of use, user satisfaction, searching utility, search failure, and outcomes. All studies were then assessed based on the framework. DATA SYNTHESIS: Due to the heterogeneity and simplistic study designs, no meta-analysis of studies could be done. General conclusions were drawn from data where appropriate. A total of 47 articles were found to include an evaluation component and were used to develop the framework. Of these, 21 articles met the inclusion criteria for 1 or more of the categories in the framework. Most use of IR systems by physicians still occurs with bibliographic rather than full-text databases. Overall use of IR systems occurs just 0.3 to 9 times per physician per month, whereas physicians have 2 unanswered questions for every 3 patients. CONCLUSIONS: Studies comparing IR systems with different searching features have not shown that advanced searching methods are significantly more effective than simple text word methods. Most searches retrieve only one fourth to one half of the relevant articles on a given topic and, once retrieved, little is known about how these articles are interpreted or applied. These studies imply that further research and development are needed to improve system utility and performance.

[Information retrieval system of the pathoanatomical department].

An information search system (ISS) of pathological archive was developed and introduced into practice in the Department of Pathomorphology of the N. V. Sklifosovsky Research Institute of Emergency. A bank of data for 1977-1979 consisting of 8400 perforated cards corresponding to 4200 autopsies has been accumulated. A computer-oriented card has been developed for recording of preadmission, clinical, and anatomical diagnosis. Treatment of the materials in a ES-1020-1022 computer permitted to reduce the labour consumption in the analysis of clinico-anatomic diagnoses, to improve the quality of documentation, and to create the bank of data based on the archives of the Pathomorphology Department. To increase the volume and value of the input information dictionaries-codifiers of various operative interventions, kinds of anesthesia, histological types of neoplasias, etc. have been created in addition to the "International Statistical Classification of Diseases, Traumas, and Causes of Death". The results obtained with the employment of the "Archive" ISS open broad prospects for creation of an automatized system of pathological archives.
