Expert searching in health librarianship: a literature review to identify international issues and Australian concerns 总被引：1，自引：1，他引：0
Lasserre K 《Health information and libraries journal》2012,29(1):3-15
Background: The traditional role of health librarians as expert searchers is under challenge. Objectives: The purpose of this review is to establish health librarians’ views, practices and educational processes on expert searching. Methods: The search strategy was developed in LISTA and then customised for ten other databases: ALISA, PubMed, Embase, Scopus, Web of Science, CINAHL, ERIC, PsycINFO, Cochrane Library and Google Scholar. The search terms were (expert search* OR expert retriev* OR mediated search* OR information retriev*) AND librar*. The searches, completed in December 2010 and repeated in May 2011, were limited to English language publications from 2000 to 2011 (unless seminal works). Results: Expert searching remains a key role for health librarians, especially for those supporting systematic reviews or employed as clinical librarians answering clinical questions. Conclusions: Although clients tend to be satisfied with searches carried out for them, improvements are required to effectively position the profession. Evidence‐based guidelines, adherence to transparent standards, review of entry‐level education requirements and a commitment to accredited, rigorous, ongoing professional development will ensure best practice. 相似文献

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. 相似文献

Objective: The paper provides an overview of a strategy to increase utilization of online bibliographic databases by public health workers.Methods: A web-based survey of professional staff in the Montana Department of Public Health and Human Services was conducted to assess their use of and interest in training in online bibliographic databases. Based on the findings from the assessment, the department, in collaboration with the state university, provided brief ninety-minute training sessions for interested staff on the use of PubMed.Results: Seventy of 115 (61%) of staff completed the survey. Only 39% of staff reported using an online bibliographic database to conduct a literature search in the past year, and only 10% (n=7) reported having ever received any training in their use. Perceived proficiency with the use of PubMed was higher upon completion of the brief training. The majority of training participants (n=27) indicated that they were very likely to use PubMed in the next year to search the literature.Conclusions: A collaboratively designed training can increase public health workers'' proficiency in and intentions of using online bibliographic databases.
Highlights
- A web-based assessment of Montana public health workers identified a lack of training in and use of online bibliographic databases and an interest in receiving training in their use.
- Brief training in the use of online bibliographic databases increased state public health workers'' self-assessed proficiency in and intentions of using these resources.
Implications
- Low-cost strategies, such as inexpensive web-survey tools, to assess staff needs and brief training sessions for public health workers were effective in increasing public health workers'' self-assessed proficiency in using online bibliographic databases.
- Collaboration between state health departments and universities to design and provide relevant training in the use of online bibliographic databases is an effective approach to addressing public health workers'' skills in using these resources.

Google is the search engine of choice for most Internet users. For a variety of reasons, librarians and other expert searchers do not always use Google to its full potential, even though it provides capabilities not possible in traditional bibliographic databases and other search engines. Applying expert searching principles and practices, such as the use of advanced search operators, information retrieval strategies, and search hedges to Google will allow health sciences librarians to find quality information on the Internet more efficiently and effectively. 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

BACKGROUND: The Internet is a valuable information tool, but users often struggle to locate good quality information from within the vast amount of information available. OBJECTIVE: The aim of the study was to identify the online information resources available to assist students develop Internet searching skills, and to explore the students' priorities in online guides. METHODS: A qualitative approach was adopted with two phases. The first was a structured search of available online study skills resources. The second comprised 10 group interviews with a total of 60 students at all stages of five undergraduate health and social care related courses at a UK university. RESULTS: The study found that there were good online guides available, but that, perversely, the better guides tended to require the best searching skills to locate them. A few students were enthusiastic about using online support, however the majority felt that if they had the skills to locate such resources they wouldn't use a study guide to improve these skills, and if they did not have the skills they would not think of using an online guide to develop them. CONCLUSIONS: Students wanted assistance when they had problems or questions, rather than sites that offered structured learning experiences. Personal support rather than virtual support was also considered to be most important to the students in this study. 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

PURPOSE: To increase understanding of the information needs and use of public health practitioners. SETTING: From June 2005 to May 2006, the library offered a course in public health information resources to eighteen practitioners in two counties, access to the library's licensed electronic resources through a tailored web portal, and consulting services. EVALUATION METHOD: We combined usage statistics from the web portal, self-report and observational data collected during training and shadowing of participants. CONCLUSIONS: The data from this project indicate that usage of licensed information resources and services is infrequent but broad ranging. A few users register at the high end of the usage range, but one use of one high quality article can have a significant impact on policy decisions. Time and competing responsibilities often constrain the retrieval and use of resources for evidence-based decision making and an informationist or power-user model may be more appropriate than training all practitioners to integrate searching into their workflow. This study indicates (i) that evidence-based public health practice requires seamless and broadly based information access; and (ii) that the currently existing patchwork does not support the level of use or take into account the time constraints of information needs for public health practice. 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

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

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

The role of librarians in addressing health insurance information needs emerged following a request from President Barack Obama for librarians to assist the public with navigating the Affordable Care Act and the Health Insurance Marketplace. The goal of this article is to highlight a number of concrete ways reference work could be expanded, especially in public library settings, to support health insurance literacy concerns by offering illustrative examples and recommendations for authoritative health insurance information resources. Overall, this article contributes to the existing literature by offering practical recommendations that may be relevant to reference librarians supporting the health insurance information needs of their communities. 相似文献

End-user search software is designed to simplify online searching for the casual searcher. User-friendly features provide relatively easy online access to remote databases without the need for expert search systems. At issue is whether the simplified features of such software compromise what is potentially retrievable, and if so, whether the missing information is critical to the end user. A study was designed to address this question, particularly as applied to clinicians using a user-friendly search software package such as Grateful Med. Clinician participants compared their Grateful Med search results with a full Elhill search (as performed by an intermediary) and indicated whether references unique to either search were or were not critical to their information needs. 相似文献

Background: Systematic reviews can provide accurate and timely information on adverse effects. An essential part of the systematic review process is a thorough search of the literature. This often requires searching many different sources. However, it is unclear which sources are most effective at providing information on adverse effects. Objective: To identify and summarise studies that have evaluated sources of information on adverse effects. Methods: Studies were located by searching in 10 databases as well as by reference checking, hand searching, citation searching and contacting experts. Results: A total of 6218 citations were retrieved yielding 19 studies which met the inclusion criteria. The included studies tended to focus on the adverse effects of drug interventions and compare the relative value of different sources using the number of relevant references retrieved from searches of each source. However, few studies were conducted recently with a large sample of references. Conclusions: This review suggests that embase , Derwent Drug File, medline and industry submissions may potentially provide the greatest number of relevant references for information on adverse effects of drugs. However, a systematic evaluation of the current value of different sources of information for adverse effects is urgently required. 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

OBJECTIVES: Medical Library Association (MLA) members were surveyed to gather background about the current state of expert searching in institutions. The survey results were intended to guide the recommendations of the Task Force on Expert Searching for promoting the importance of expert searching and implementing those recommendations. METHODS: MLA members were surveyed, and data obtained from the survey were compiled and analyzed to answer three general questions: what is the perceived value of searching skills to the institution, how do health sciences librarians maintain and improve their searching skills, and how are searching services promoted and/or mandated in the institution. RESULTS: There were 256 responses to the survey. Over 95% of the respondents saw their expert-searching skills were of value to their institutions, primarily through performing mediated searches and search consultations. Over 83% of the respondents believed that their searching skills had improved over the past 10 years. Most indicated that continued training was very important in maintaining and improving their skills. Respondents promoted searching services most frequently through orientations, brochures, and the libraries' Web pages. No respondent's institution mandated expert searching. Less than 2% of respondents' institutions had best practice guidelines related to expert searching, and only about 8% had guidelines or policies that identified situations where expert searching was recommended. CONCLUSIONS: The survey supports the belief that health sciences librarians still play a valuable role in searching, particularly in answering questions about treatment options and in providing education. It also highlights the need for more expert searching courses. There has been minimal discussion about the perceived need for expert-searching guidelines in the institutions represented by survey respondents. 相似文献

The availability of web search engines offers opportunities in addition to those provided by bibliographic databases for identifying academic literature, but their usefulness for retrieving research is uncertain. A rigorous literature search was undertaken to investigate whether web search engines might replace bibliographic databases, using empirical research in health and social care as a case study. Eight databases and five web search engines were searched between 20 July and 6 August 2015. Sixteen unique studies which compared at least one database with at least one web search engine were examined, as well as drawing lessons from the authors’ own search process. Web search engines were limited in that the searcher cannot be certain that the principles of Boolean logic apply and they were more limited than bibliographic databases in their functions, such as exporting abstracts. Recommendations are made for improving the rigour and quality of reporting studies of academic literature searching. 相似文献

OBJECTIVES: This research was conducted to provide new insights on clinical nurses' and nursing students' current use of health resources and libraries and deterrents to their retrieval of electronic clinical information, exploring implications from these findings for health sciences librarians. METHODS: Questionnaires, interviews, and observations were used to collect data from twenty-five nursing students and twenty-five clinical nurses. RESULTS: Nursing students and clinical nurses were most likely to rely on colleagues and books for medical information, while other resources they frequently cited included personal digital assistants, electronic journals and books, and drug representatives. Significantly more nursing students than clinical nurses used online databases, including CINAHL and PubMed, to locate health information, and nursing students were more likely than clinical nurses to report performing a database search at least one to five times a week. CONCLUSIONS AND RECOMMENDATIONS: Nursing students made more use of all available resources and were better trained than clinical nurses, but both groups lacked database-searching skills. Participants were eager for more patient care information, more database training, and better computer skills; therefore, health sciences librarians have the opportunity to meet the nurses' information needs and improve nurses' clinical information-seeking behavior. 相似文献
