OBJECTIVE: The article explores the characteristics of public health information needs and the resources available to address those needs that distinguish it as an area of searching requiring particular expertise. METHODS: Public health searching activities from reference questions and literature search requests at a large, urban health department library were reviewed to identify the challenges in finding relevant public health information. RESULTS: The terminology of the information request frequently differed from the vocabularies available in the databases. Searches required the use of multiple databases and/or Web resources with diverse interfaces. Issues of the scope and features of the databases relevant to the search questions were considered. CONCLUSION: Expert searching in public health differs from other types of expert searching in the subject breadth and technical demands of the databases to be searched, the fluidity and lack of standardization of the vocabulary, and the relative scarcity of high-quality investigations at the appropriate level of geographic specificity. Health sciences librarians require a broad exposure to databases, gray literature, and public health terminology to perform as expert searchers in public health. 相似文献

This paper discusses the challenges of finding evidence needed to implement Evidence-Based Librarianship (EBL). Focusing first on database coverage for three health sciences librarianship journals, the article examines the information contents of different databases. Strategies are needed to search for relevant evidence in the library literature via these databases, and the problems associated with searching the grey literature of librarianship. Database coverage, plausible search strategies, and the grey literature of library science all pose challenges to finding the needed research evidence for practicing EBL. Health sciences librarians need to ensure that systems are designed that can track and provide access to needed research evidence to support Evidence-Based Librarianship (EBL). 相似文献

A formal study was attempted to assess the utility of the various online database sources for obtaining material in the fields of occupational and environmental health. Five databases were studied comparatively: BIOSIS, ENVIROLINE, EXCERPTA MEDICA, MEDLINE, and TOXLINE. In addition to crossdatabase searching to draw comparisons, a study of the journal coverage of four of these databases was completed. The goal of this effort was to establish some "databases of choice" for searching the literature. 相似文献

A mobile site redesign was conducted at a medium-sized academic health sciences library with the goal of creating a site that meets the mobile information needs of its users. The redesign phases included (1) needs assessment, (2) usability testing, and (3) site design. The survey results showed that Apple devices were the most prevalent; the most desirable activities performed on a mobile site were searching for articles, accessing full-text articles and e-books, searching databases, and searching the catalog. These activities guided the development of the usability testing tasks and the redesign. All phases were completed within six months, and the total project cost was $50 for incentive purchases. 相似文献

The objective was to assess the effect on health professionals' skills of one to eight hours literature search and retrieval training from electronic health databases. We searched: Cochrane library (2002; Issue 3), MEDLINE (1977-2002/5), EMBASE (1980-2002/7); CINAHL (1982-2002/5); ASSIA (1982-2002/7), BNI (1994-2002/5), ERIC (1985-2002/6); LISA (1969--current), NRR (2002, Issue 2), the world-wide-web and references. The selection criteria consisted of randomised controlled trials, controlled before and after, and controlled cohort studies in comparison with no training. The intervention had to be one to eight hours training in literature search and retrieval skills for health professionals. The outcome was the effect on health professionals' literature search and retrieval skill levels measured through reliable instruments. For data collection and ana-lysis, one reviewer extracted data and assessed the quality of the studies and the second reviewer checked it. The results indicate that there is some evidence of positive impact on health professionals' skill levels in literature searching and they find the training useful. In conclusion, the size of the positive effect is debatable as only three small and methodologically weak studies met the inclusion criteria and out of those only two showed the positive effect. 相似文献

Zoological medicine furthers the health and well-being of captive and free-ranging wild animals. Effective information retrieval of the zoological medicine literature demands searching multiple databases, conference proceedings, and organization websites using a wide variety of keywords and controlled vocabulary. Veterinarians, residents, students, and the librarians who serve them must have patience for multiple search iterations to capture the majority of the available knowledge. The complexities of thorough literature searches are more difficult for nondomestic animal clinical cases and research reviews as demonstrated by three search requests involving poisonous snakes, a gorilla, and spiders. Expanding and better disseminating the knowledgebase of zoological medicine will make veterinary searching easier. 相似文献

The purpose of this research was to determine which of three databases, CINAHL, EMBASE or MEDLINE, should be accessed when researching nursing topics. The three databases were searched for citations on topics selected by three nurse researchers and the results were compared. For the search of nursing care literature on a medical condition, it was helpful to search both CINAHL and MEDLINE. CINAHL provided the majority of relevant articles for the second search, on computers and privacy, but inclusion of MEDLINE and EMBASE enhanced retrieval somewhat. The search on substance abuse in pregnancy, not restricted to nursing literature, retrieved better results when searching both MEDLINE and EMBASE. Due to the nature and distribution of the nursing literature, it is especially important for the searcher to understand and respond to the focus of the researcher. 相似文献

Problems in online retrieval of information concerning medical devices are discussed, including background data regarding legislative history and terminology. An analysis of the results of searching on ten sample topics in this subject area provides a framework for approaching such problems. In addition to a consideration of recall, uniqueness, and overlap, other factors influence database selection and order of consultation. Indexing characteristics of selected health science, engineering, business, and regulatory databases play a major role in medical device information provision. 相似文献

Purpose: To characterise the training needs of those providing clinical question answering services (CQAS). Participants: Seventeen specialist UK staff working in CQAS, 21 from general health library UK staff and eight international respondents. Methodology: A literature review examined documented training needs for CQAS staff. A follow‐up questionnaire examined prior training and experience and identified training needs for the surveyed staff. Results/outcomes: Ninety per cent of CQAS staff had worked in health services for 3 years or longer. Training received in preparation for the CQAS role comprised literature searching (including the PRECEPT/ADEPT and cochrane library courses) and critical appraisal. Skills considered ‘essential’ for clinical question answering were ‘literature searching’ (100%), ‘understanding the context of clinical questions’, ‘bibliographic databases’, ‘evidence‐based sources’ and ‘the Internet’ (all 93%). Main training needs for specialist CQAS staff include management and organisation of CQAS and technical skills in interpretation and presentation. Discussion/conclusion: CQAS staff require a formal training programme. Most CQAS staff considered that this should be a mandatory requirement. 相似文献

Comparison of bibliographic databases for information on the rehabilitation of people with severe mental illness 总被引：1，自引：0，他引：1
OBJECTIVE: The research sought to examine the overlap in coverage between several health-related databases, thus enabling the identification of the most important sources for searching for information on the rehabilitation of people with severe mental illness. METHODS: The literature was searched within a systematic review. Several health-related databases were retrieved (Cumulative Index to Nursing and Allied Health Literature, The Cochrane Library, MEDLINE, PsycLIT, Sociofile, and Social Science Citation Index), noting their source and comparing results retrieved from each database. FINDINGS: The total number of studies retrieved from each database varied. Almost a third of the papers retrieved from each database were unique to that source. Forty-two percent of the papers were only found in one database. Restricting a search to one database alone would miss many papers and could affect the results of a systematic review. PsycLIT was the most useful database for this topic area, containing 44% of the papers. MEDLINE, the database of first choice for many health professionals, held only 29%. CONCLUSIONS: No database was determined to be significantly more useful than any other--each warranted inclusion in the study. Reliance cannot be placed on one database alone, and other methods such as hand searching should also be used. Although this may not be new information for information professionals, it is likely to be new for health professionals and researchers who are increasingly performing their own literature searches. Information professionals have an important role to play in conveying this message to those outside their profession. 相似文献

Previous information retrieval research has neglected examination of older adults' search behavior. The present study examined the online search performance and associated errors of 54 older adult users of a representative online library catalog system. Participants' error data were examined in the framework of Borgman's three layers of knowledge needed to perform online library catalog searching: (1) conceptual knowledge, (2) semantic knowledge, and (3) technical skills in executing the query. The results of older adults were consistent with findings of previous online library catalog studies with younger adults. Older adults experienced serious problems at all three knowledge layers but experienced their most severe difficulties with conceptual knowledge of how to search the online library catalog system (e.g., formulating queries, understanding and using keyword and Boolean searching, and understanding the contents of databases). The significance of these findings for older adults' use of online library catalogs will be discussed. 相似文献

The NLM Gateway is a single Web interface for searching multiple NLM databases. While the majority of the available databases can be accessed directly via their own Web sites, such as PubMed, there are three databases that are unique to the NLM Gateway, including the ever-expanding OLDMEDLINE files. Thus, the Gateway is a necessary tool for librarians and researchers to be familiar with and have handy. 相似文献

An exploratory study to investigate perceived differences between searching full-text databases and bibliographic databases was undertaken. BRS's full-text database, Comprehensive Core Medical Library (CCML), and BRS's current MEDLINE file (MESH) were compared. Identical literature search topics were run in the two databases and the results evaluated regarding currency of search results, success in answering specific questions, uniqueness of information retrieved, and relevancy of retrieval. Additionally, connect time and costs were noted to aid in determining the feasibility of offering full-text database searching as a service for which the authors' institution would charge. 相似文献

AbstractThis study examines the promotion and knowledge of online patent literature search among students, librarians, and instructors to enhance university scientific output in Zanzibar. The study was guided by four key questions: What is the level of awareness of students, instructors and library staff about patent documents as source of information? To what extent do students and instructors access online patent databases? What is the library experience in training students about online patent literature searching?, and what are the challenges facing library and instructors in promoting patent literature search? The study used survey approach whereby questionnaire and interview were used to collect data. The recent literatures regarding online patent literature searching were also critically reviewed. A survey was conducted at two Universities in Zanzibar namely the State University of Zanzibar and Zanzibar University, whereby 20 library staff, 10 instructors and 140 undergraduate students from the School of Computing and the Faculty of Engineering were involved in this study. The findings show that more than three quarters of respondents were either partially aware or not aware at all about the existence of free online patent databases. Likewise, the majority of students had no enough skills of patent literature searching. However, usually the library organizes training on general online literature searching skills but patent literature searching was not effectively taught and a big challenge observed in this study regarding promotion of patent literature searching is inadequate patent searching skills among library and instructors. Based on the findings, the study proposed several recommendations to rectify the existing problem. 相似文献

Background: Literature for a systematic review on the student experience of e‐learning is located across a range of subject areas including health, education, social science, library and information science. Objectives: To assess the merits and shortcomings of using different search techniques in retrieval of evidence in the social science literature. Methods: A conventional subject search was undertaken as the principal method of identifying the literature for the review. Four supplementary search methods were used including citation searching, reference list checking, contact with experts and pearl growing. Results: The conventional subject search identified 30 of 41 included references; retrieved from 10 different databases. References were missed by this method and a further 11 references were identified via citation searching, reference list checking and contact with experts. Pearl growing was suspended as the nominated pearls were dispersed across numerous databases, with no single database indexing more than four pearls. Conclusions: Searching within the social sciences literature requires careful consideration. Conventional subject searching identified the majority of references, but additional search techniques were essential and located further high quality references. 相似文献
