Using EndNote version 7.0, the authors tested the search capabilities of the EndNote search engine for retrieving citations from MEDLINE for importation into EndNote, a citation management software package. Ovid MEDLINE and PubMed were selected for the comparison. Several searches were performed on Ovid MEDLINE and PubMed using EndNote as the search engine, and the same searches were run on both Ovid and PubMed directly. Findings indicate that it is preferable to search MEDLINE directly rather than using EndNote. The publishers of EndNote do warn its users about the limitations of their product as a search engine when searching external databases. In this article, the limitations of EndNote as a search engine for searching MEDLINE were explored as related to MeSH, non-MeSH, citation verification, and author searching. 相似文献

The study examined and assessed the search techniques of trained end-users and determined whether or not they were searching the system effectively. One hundred and thirty-one users searched a full-text system and completed a survey that asked them to evaluate the system and describe their search strategy and techniques. Overall, 55% of the total indicated dissatisfaction with their searches. Correlations between native language and searching results and satisfaction are shown. These findings suggest that computer literate end-users with prior experience searching other databases and formal training experience more difficulties than is commonly realized. Implications for training are discussed. 相似文献

Through casual observations, formal consultations, and educational sessions, the authors have identified various indexing features of the National Library of Medicine's Medical Subject Headings (MeSH) that pose challenges to end users while attempting to obtain relevant retrieval when searching MEDLINE. These problematic features include the use of Explodes, Tree structures, subheadings, Text Word vs. subject heading searching, and central concept searching. End-user search software is becoming more sophisticated with an increasing number of choices offered for search strategy formulation. Methods of instruction to orient the end user to these systems will also have to become more detailed. A review of the literature, that discusses end-user problems with using MEDLINE and MeSH, is included. 相似文献

The MELVYL MEDLINE project resulted in the addition of a full five-year subset of MEDLINE to the University of California's (UC) MELVYL online union catalog. As one of the nation's largest MEDLINE end-user searching systems, MELVYL MEDLINE provides online bibliographic access to the biomedical journal literature for all UC personnel at over seventy library sites or by remote access. This paper summarizes the project's accomplishments, reports MELVYL MEDLINE use and its impact on library services, and provides insights for other end-user search systems. The project serves as a model for adding databases to the MELVYL catalog and demonstrates the potential for use by other disciplines of a specialized database when readily accessible. Evaluation results report high user satisfaction and high usage. However, many advanced searching features of the interface are little used by searchers. Effects on library services include marked increases in reference transactions and interlibrary loans, with significant declines in mediated search services. Future MELVYL MEDLINE enhancements include matching search retrievals to journal locations, linkage to an online document delivery system, and consideration of building a superset of databases by combining MELVYL MEDLINE with citations from another database in the MELVYL catalog. 相似文献

The Alfred Taubman Medical Library at the University of Michigan has offered instruction in online literature searching to third-year pharmacy students as a component of the course "Drug Information and Scientific Literature Evaluation" since 1983. In the spring of 1989, a follow-up study was conducted to assess the impact of instruction on four classes of graduates. Of a pool of 151 graduates, 90 (60%) responded to a mailed questionnaire on their use of information and computerized literature searching. The respondents were divided into four subgroups: end-user searchers, users of intermediaries, end users who used intermediaries, and those who did not use computerized literature search systems. Seventy-two percent of the respondents used some type of computerized literature searching, and 42% performed their own searches. The four subgroups differed in general computer use, familiarity with MEDLINE search terminology, information use, reasons for using or not using literature searching, and characteristics of searches (i.e., type, time frame, amount, and frequency). Training in end-user search systems appears to have had an impact on the continued use of computerized literature searching several years after the formal educational program. 相似文献

This study analyzes the search behavior of end users who had taken a class in searching MEDLINE on the National Library of Medicine's MEDLARS system. Of the class alumni, 58% obtained passwords. Most of these were still conducting their own searches twelve to eighteen months later. Telephone interviews and search observations indicated that these end users were satisfied with their results and felt they had mastered the basic mechanics of searching. However, appropriate use of explodes and subheadings, as well as locating appropriate search terms, still presented difficulties for them. Further training in these areas may be required. 相似文献

Although database access has been available via search intermediaries for some time, online services are now encouraging end users to search databases directly. In response to this trend, librarians are taking on new end-user training and support roles. But is this training effort worthwhile? The relationship between online training received and the level of implementation of end-user searching is discussed using survey data from 124 Canadian health professionals (response rate 83%). There was a positive relationship between the number of training events reported and implementation level. Several different kinds of training, in addition to formal courses, were reported by end users. The use of Medical Subject Headings (MeSH) was related to more positive perceptions of online searching which, in turn, predicted higher implementation levels. Variability in the implementation levels of the respondents suggests that end users are a diverse group with different information needs and degrees of searching expertise. Various types of both formal and informal training will continue to be required by end users. 相似文献

A survey to determine attitudes toward end-user searching was made at Loyola University's Medical Center Library using MEDIS, an online full-text and bibliographic medical retrieval system. One hundred forty-one completed questionnaires were analyzed for this report. Information was collected on user familiarity with computers, end-user training, system use, mechanics of searching, and attitudes toward future use. Computer familiarity was highest among the faculty users. Ninety percent of the respondents saw librarians as a crucial agent in training and in providing end-user assistance. Respondents identified five major reasons for using the system: helpfulness, convenience, time savings, rapid feedback, and presentation of needed information. Searching the MEDLINE database rather than the full-text database was the search method of choice. Continued use of both mediated and end-user searching was intended by most of the respondents. Survey results support a perceived need for end-user searching and confirmed recommendations of the Association of American Medical Colleges on medical information science skills. 相似文献

The development of user-friendly search systems has enabled physicians to perform their own MEDLINE searches. These physicians are recognizing a need to learn how to organize their growing reprint collections. Librarians at the University of Michigan, Alfred Taubman Medical Library have developed a unique course that presents a variety of techniques to meet the needs of a wide audience. For some users, such as students or house officers who have limited funds or lack support devices, a variety of manual methods are presented. Advantages and disadvantages of using manual versus computerized systems are discussed. Following the illustration of the manual methods, users are introduced to a simple computerized method using a utility type database management package, PC-FILE. Hands-on training under the direction of librarians allows students to develop and use a practice database while having experts available to answer questions. Users are encouraged to take a copy of PC-FILE (shareware) with them to experiment with before committing themselves to a more expensive database management software package. Before the class ends, those interested in a more sophisticated package with specialized report formats and downloading/uploading capabilities are given a brief demonstration of PRO-CITE. Evaluations have shown that there is interest in all three methods. 相似文献

The emergence of CD-ROM (compact disc/read-only memory) versions of the MEDLINE database requires experienced MEDLINE searchers to examine assumptions about searching MEDLINE, since some expectations may not be fulfilled by this new technology. When applied to a particular CD-ROM MEDLINE product, the evaluation procedure involves testing assumptions concerning database contents; mechanics of searching; display, print, and download capabilities; and user-friendly features. The extent to which a CD-ROM product preserves and exploits important MEDLINE strengths should be assessed, e.g., the MeSH controlled vocabulary, the designation of major and minor MeSH emphasis, and the use of subheadings. Search software characteristics that affect ease of searching and quality of results also need to be examined, e.g., the ability to truncate search terms and the order of precedence in which Boolean operators are evaluated. A checklist to assist in the evaluation process is presented, including search examples for use in testing search functions. 相似文献

The effect of introducing user fees on the frequency and quality of MEDLINE searching with GRATEFUL MED by physicians in clinical settings was tested. After training and free use (prior study), consenting participants were randomly allocated to pay searching costs (pay group) or continue without fees (no pay group). Fifty-nine physicians participated. Among the prior study's frequent searchers, the pay group searched at less than one third of the rate of those assigned to no pay. For less frequent searchers in the prior study, only 48% of those assigned to pay did any searches, compared with 85% for the no pay group (P = 0.006), and for those who did search, their frequency was almost half. However, there was no significant difference in the quality of searches; both groups demonstrated about equivalent recall (P = 0.77), but significantly lower precision (P = 0.03) than for the librarian's independent searches. Similarly, there was no difference in the proportion of searches affecting clinical decisions for the two groups. Thus, imposing user charges for online searching in clinical settings after a period of free use adversely affects searching quantity, but not quality. MEDLINE providers should consider whether user fees will undermine its benefits. 相似文献

The nature of bibliographic instruction in this hospital library continues to evolve. As the library makes easy-to-master, menu-driven tools for online searching available to end users, the demand for this service and the accompanying training increases. The demand for formal sessions covering research techniques is also increasing. Upon request, the library offered an extended research orientation to the housestaff in Obstetrics and Gynecology in May of 1993. An introduction to the use of CD-ROM was included to highlight its usefulness for citation verification, author searches, and for periodic current awareness searches on a particular topic. The UMH Library staff strive to offer the most current and comprehensive facilities and services to their users. These include automated access to the library's book, journal, and audiovisual holdings using the Data Trek system; online bibliographic searching by library staff and end users using CD Plus MEDLINE on CD-ROM and Grateful MED software; participation in clinical rounds to provide research support for clinical care; and several types of bibliographic instruction. In addition to the informal teaching of library research techniques that the library staff offers on a daily basis, the Library at Union Memorial Hospital is pleased to be able to provide a formalized and evolving bibliographic instruction program. 相似文献

Objective: To identify or develop a critical appraisal instrument (CAI) to aid in the selection of search filters for use in systematic review searching. The CAI is to be used by experienced searchers without specialized training in statistics or search filter design. Methods: Through extensive searching and consultation, one candidate instrument was identified. Through expert consultation and several rounds of testing, the instrument was extensively revised to become the Canadian Agency for Drugs and Technologies in Health (CADTH) CAI. Results: The CADTH CAI consists of ten questions and can be applied by experienced searchers with a moderate knowledge of search filter methodology. Conclusion: The CADTH CAI provides experienced searchers with a means of selecting the search filter that is most methodologically sound. 相似文献

Background: Search filters have been developed in MEDLINE and EMBASE to help overcome the challenges of searching electronic databases for information on adverse effects. However, little evaluation of their effectiveness has been carried out. Objectives: To measure the sensitivity and precision of available adverse effects search filters in MEDLINE and EMBASE. Methods: A case study systematic review of fracture related adverse effects associated with the use of thiazolidinediones was used. Twelve MEDLINE search strategies and three EMBASE search strategies were tested. Results: Nineteen relevant references from MEDLINE and 24 from EMBASE were included in the review. Four search filters in MEDLINE achieved high sensitivity (95 or 100%) with an improved level of precision from searches without any adverse effects filter. High precision in MEDLINE could also be achieved (up to 53%) using search filters that rely on Medical Subject Headings. No search filter in EMBASE achieved high precision (all were under 5%) and the highest sensitivity in EMBASE was 83%. Conclusions: Adverse effects search filters appear to be effective in MEDLINE for achieving either high sensitivity or high precision. Search filters in EMBASE, however, do not appear as effective, particularly in improving precision. 相似文献

To determine possible uses for MEDLINE in the hospital library, health practitioners requesting literature searches were provided with both a manual and a MEDLINE search. Patron receptivity to MEDLINE was good, but the manual search was more often preferred. The health practitioners responding to a questionnaire apparently had delegated literature searching and evaluation of material to the hospital librarians, especially when clinically related information was needed. In the community hospitals where both the search and the selection of material are the responsibility of the librarian, MEDLINE can be used as the primary search tool or to supplement material provided. 相似文献

MEDLINE (MEDLARS-ON-LINE) is the new on-line, interactive bibliographic searching system which was recently developed by the National Library of Medicine. The system provides users with lists of bibliographical citations and other information from a three-year file of over 1,250 biomedical journals. A survey testing user reactions was conducted at the University of Virginia Medical Library. The results of the survey are based on replies by 246 users who requested one or more MEDLINE searches between September 1972 and March 1973. The findings indicate that over 93% believe that MEDLINE is a substantial improvement over the traditional methods of searching through the printed indexes. These respondents also stated that the results of MEDLINE searches had assisted them in their clinical or research work, or both. Asked whether they would continue to use MEDLINE after the imposition of user charges on July 1, 1973, about 75% said that they would. The remaining 25% expressed some reservations and doubts. The survey gives reason to believe that with the imposition of user charges the use of MEDLINE will decline. 相似文献
