Bibliometric study of grey literature in core veterinary medical journals.

OBJECTIVES: Grey literature has been perceived by many as belonging to the primary sources of information and has become an accepted method of nonconventional communication in the sciences and medicine. Since little is known about the use and nature of grey literature in veterinary medicine, a systematic study was done to analyze and characterize the bibliographic citations appearing in twelve core veterinary journals. METHODS: Citations from 2,159 articles published in twelve core veterinary journals in 2000 were analyzed to determine the portion of citations from grey literature. Those citations were further analyzed and categorized according to the type of publication. RESULTS: Citation analysis yielded 55,823 citations, of which 3,564 (6.38%) were considered to be grey literature. Four veterinary specialties, internal medicine, pathology, theriogenology, and microbiology, accounted for 70% of the total number of articles. Three small-animal clinical practice journals cited about 2.5-3% grey literature, less than half that of journals with basic research orientations, where results ranged from almost 6% to approximately 10% grey literature. Nearly 90% of the grey literature appeared as conferences, government publications, and corporate organization literature. CONCLUSIONS: The results corroborate other reported research that the incidence of grey literature is lower in medicine and biology than in some other fields, such as aeronautics and agriculture. As in other fields, use of the Internet and the Web has greatly expanded the communication process among veterinary professionals. The appearance of closed community email forums and specialized discussion groups within the veterinary profession is an example of what could become a new kind of grey literature.

Information and research needs of acute-care clinical nurses.

The majority of nurses surveyed used the library on a regular but limited basis to obtain information needed in caring for or making decisions about their patients. A minority indicated that the libraries in their own institutions totally met their information needs. In fact, only 4% depended on the library to stay abreast of new information and developments in the field. Many of the nurses had their own journal subscriptions, which could account in part for the limited use of libraries and the popularity of the professional journal as the key information source. This finding correlates with the research of Binger and Huntsman, who found that 95% of staff development educators relied on professional journal literature to keep up with current information in the field, and only 45% regularly monitored indexing-and-abstracting services. The present study also revealed that nurses seek information from colleagues more than from any other source, supporting the findings of Corcoran-Perry and Graves. Further research is necessary to clarify why nurses use libraries on a limited basis. It appears, as Bunyan and Lutz contend, that a more aggressive approach to marketing the library to nurses is needed. Further research should include an assessment of how the library can meet the information needs of nurses for both research and patient care. Options to be considered include offering library orientation sessions for new staff nurses, providing current-awareness services by circulating photocopied table-of-contents pages, sending out reviews of new monographs, inviting nurses to submit search requests on a topic, scheduling seminars and workshops that teach CD-ROM and online search strategies, and providing information about electronic databases covering topics related to nursing. Information on databases may be particularly important in light of the present study's finding that databases available in CD-ROM format are consulted very little. Nursing education programs should be expanded to include curricula bibliographic sessions where the librarian, in cooperation with the teaching faculty, visits the classroom to explain all pertinent information sources or invites the class to the library for hands-on demonstration and practice. Nurses who gain working knowledge of the tools that open the doors to retrieval of research findings and who have information about new innovations in medicine and medical technology have superior chances for success in their chosen profession.

Decision support for clinical trial eligibility determination in breast cancer.

We have developed a system for clinical trial eligibility determination where patients or primary care providers can enter clinical information about a patient and obtain a ranked list of clinical trials for which the patient is likely to be eligible. We used clinical trial eligibility information from the National Cancer Institute's Physician Data Query (PDQ) database. We translated each free-text eligibility criterion into a machine executable statement using a derivation of the Arden Syntax. Clinical trial protocols were then structured as collections of these eligibility criteria using XML. The application compares the entered patient information against each of the eligibility criteria and returns a numerical score. Results are displayed in order of likelihood of match. We have tested our system using all phase II and III clinical trials for treatment of metastatic breast cancer found in the PDQ database. Preliminary results are encouraging.

Optimal search strategy for clinical trials in the Latin American and Caribbean Health Science Literature Database (LILACS).

OBJECTIVE: To define and disseminate the optimal search strategy for clinical trials in the Latin American and Caribbean Health Science Literature (LILACS). This strategy was elaborated based on the optimal search strategy for MEDLINE recommended by Cochrane Collaboration for the identification of clinical trials in electronic databases. DESIGN: Technical information. SETTING: Clinical Trials and Meta-Analysis Unit, Federal University of São Paulo, in conjunction with the Brazilian Cochrane Center, São Paulo, Brazil. (http://www.epm.br/cochrane). DATA: LILACS/CD-ROM (Latin American and Caribbean Health Science Information Database), 27th edition, January 1997, edited by BIREME (Latin American and Caribbean Health Science Information Center). LILACS Indexes 670 journals in the region, with abstracts in English, Portuguese or Spanish; only 41 overlap in the MEDLINE-EMBASE. Of the 168,902 citations since 1982, 104,016 are in human trials, and 38,261 citations are potentiality clinical trials. Search strategy was elaborated combining headings with text word in three languages, adapting the interface of the LILACS. We will be working by locating clinical trials in LILACS for Cochrane Controlled Trials Database. This effort is being coordinated by the Brazilian Cochrane Center.

The Cochrane Library: a resource for current reviews of clinical evidence.

The Cochrane Library is a tool for physicians and other health care practitioners seeking evidence to inform their decisions. The systematic reviews provide a high-quality synthesis of the current literature, saving time for busy people. To make the library more user-friendly, the collaboration plans to produce a consumer summary for each topic in the Database of Systematic Reviews and a cancer library aimed at the general public. In contrast to some of the questionable health-related resources on the Web, the Cochrane Library is an authoritative reference that can help physicians with everyday treatment decisions. The collaboration's commitment to keeping its resources up to date through vigorous support of reviewers should ensure that it remains a valuable Internet tool for physicians.

[Structured abstracting of scientific medical publications].

Abstracts play an important role in medical literature as the carriers of synthetic information. Their significance grows as computerized data bases are in use in which whole information should comprise no more than 250 words. Critical appraisal the abstracts' standard resulted in a proposal for data presentation divided into significant parts (structured abstracts). The abstract of an original clinical trial should contain description of the objective, design, setting, patients, intervention, main outcome measures, results and conclusions. The abstract of the review article should provide information about the purpose, data identification, study selection, data extraction, results of data synthesis and conclusions. This form obliges the authors to precise, logical formulation draws out the essential aspects of the work, facilitates literature review, and critical appraisal.

Clinical studies in orthodontics--an overview of NIDR-sponsored clinical orthodontic studies in the US.

A number of clinical trials sponsored by the National Institutes of Health (NIH) use rigorous methods of data acquisition and analysis previously developed in fundamental biology and the physical sciences. The naive expectation that these trials would lead relatively rapidly to definitive answers concerning the therapeutic strategies and techniques under study is dispelled. This presentation focuses on delineating differences between the study of central tendencies and individual variation, more specifically on the strategy to study this variation: measure additional sources of variance within each patient at more timepoints and perhaps with greater precision. As rigorous orthodontic research is still in its infancy, the problem of defining the proper mix between prospective and retrospective trials is discussed. In view of the high costs of prospective clinical trials, many of the questions germane to orthodontics can be answered by well-conducted retrospective trials, assuming that properly randomized sampling procedures are employed. Definitive clinical trials are likely to require better theoretical constructs, better instrumentation, and better measures than now available. Reasons for concern are the restricted resources available and the fact that current mensurational approaches may not detect many of the individual differences. The task of constructing sharable databases and record bases stored in digital form and available either remotely from servers, or locally from CD-ROMs or optical disks, is crucial to the optimization of future investigations.

[Evidence based medicine for the gastroenterologist].

Evidence-based medicine (EBM) integrates the best available external evidence in the care of individual patients with the individual clinical expertise and the patient preferences. This method has been designed for use in daily clinical practice. We describe the rationale for EBM and its principles and application in this article. EBM enables gastroenterologists to update the knowledge required to provide patients with high quality medical care. EBM requires four steps: a) formulating a clinical question arising from a doubt concerning a patient; b) conducting an efficient literature search to answer this question; c) critically appraising this evidence using explicit methods to selected articles to determine the validity of their design and the clinical relevance of their results; and d) applying these results to the patient (taking into account their values and preferences and personal and social circumstances). In this paper, we explain the principles and basic concepts of EBM and their application to gastroenterology and we provide an extensive compilation of internet databases of valid information relevant to gastroenterologists. We also provide a selection of useful tools for self-directed learning of critical appraisal skills. Link updates can be accessed at the following URL: http://www.enlacesmedicos.com/e.htm
