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

Background and objective: With the advent of an interprofessional approach to delivering health care in today's health care systems, should health care professionals be educated together? Supported by policy‐making circles worldwide, interprofessional education is accumulating a research literature at an exponential rate. Using one‐word search terms in the medline query box for scoping this body of literature, we obtained an unmanageable number of articles (342 338 in all fields). The objective of our study was to outline an efficient specific query. Methods: We created 1072 phrasal search terms consisting of a prefix, an adjective and a noun. Of those, 66 were prolific for the whole indexed period (1950–2006). Results: Only 2510 citations have the search term in all medline fields; of those 2049 were in title/abstract and 652 in title alone. From the 1950s, the citations were published at a slow rate, but the rate then exploded during the decade 1995 to 2006. The combination of prefixes ‘inter’ and ‘multi’ with the adjectives ‘professional’, ‘disciplinary’ and ‘shared’, and the nouns ‘education’, ‘learning’ and ‘training’ may retrieve almost all the relevant citations, while the terms ‘collaborative’ and ‘common’ may retrieve mainly irrelevant ones. The adjective ‘cohesive’ and nouns ‘practice’ and ‘role’ should be also considered. Conclusion: Phrasal search terms highly increased the relevance of medline ‐retrieved citations.  相似文献

To determine the mix of resources used in social gerontology research, a citation analysis was conducted. A representative sample of citations was selected from three prominent gerontology journals and information was added to determine subject scatter and database coverage for the cited materials. Results indicate that a significant portion of gerontology research, even from a social science perspective, relies roughly equally on medical resources as it does social science resources. Furthermore, there is a small but defined core of literature constituting scholarly “territory” unique to gerontology. Analysis of database indexing indicated that broad, interdisciplinary databases provide more comprehensive coverage of the cited materials than do subject-specific databases.  相似文献

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

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.

BACKGROUND: The University of Sofia, Bulgaria, disseminates local biomedical literature (1994 to present) through a free online database, ABS. OBJECTIVES: Our objectives were to systematically search ABS, identify citations to controlled trials and discover what proportion of these studies are to be found on medline. METHODS: We searched using Bulgarian and English phrases; manually selected citations of controlled trials and sought these citations on medline. Results: Using the two languages, we found a total of 628 unique citations, 47 of which seem to be relevant controlled trials (precision 7.48%, 13% of ABS citations were found on medline). The trials in ABS commonly focused on evaluation of care for people with cardiovascular or urological problems. DISCUSSION: ABS is another source of easily accessed trials not readily available elsewhere.  相似文献

Objectives: National databases may be useful sources in the production of a systematic review (SR). The aim of this study was to assess the potential benefit of a systematic search in the German database ‘Current Contents Medizin’ (CCMed ). Methods: The study was conducted on the basis of published SRs that included CCMed as a literature source. Eligible SRs were identified through a systematic search in medline , embase and The Cochrane Library. The websites of German Health Technology Assessment agencies were also screened. Citations of primary studies included as relevant in the SRs were extracted and then categorised. Results: The search yielded 52 eligible SRs. A total of 1505 relevant citations were extracted. Seventy‐seven of these articles were published in journals indexed in CCMed . Thirty‐two of the 77 citations were indexed in CCMed , but only eight of the 32 were unique. Of these eight citations, seven were not identified by a systematic search, but by handsearching. Only one unique citation, an observational study, was identified in CCMed by a systematic search. Conclusions: In the production of SRs, a systematic search in CCMed identifies relevant studies only in exceptional cases. Therefore, the routine inclusion of this database in systematic searches does not appear meaningful.  相似文献

The performance of adverse effects search filters in MEDLINE and EMBASE   总被引:1,自引:1,他引:0  
Background: Search filters can potentially improve the efficiency of searches involving electronic databases such as medline and embase . Although search filters have been developed for identifying records that contain adverse effects data, little is known about the sensitivity of such filters. Objectives: This study measured the sensitivity of using available adverse effects filters to retrieve papers with adverse effects data. Methods: A total of 233 included studies from 26 systematic reviews of adverse effects were used for analysis. Search filters from medline and embase were tested for their sensitivity in retrieving the records included in these reviews. In addition, the sensitivity of each individual search term used in at least one search filter was measured. Results: Subheadings proved the most useful search terms in both medline and embase . No indexing terms in medline achieved over 12% sensitivity. The sensitivity of published search filters varied in medline from 3% to 93% and in embase from 57% to 97%. Whether this level of sensitivity is acceptable will be dependent on the purpose of the search. Conclusions: Although no adverse effects search filter captured all the relevant records, high sensitivity could be achieved. Search filters may therefore be useful in retrieving adverse effects data.  相似文献

OBJECTIVE: To describe the development of the Cochrane Behavioral Medicine Field database of interventions and its contribution to the knowledge base of this field. METHODS: A list of behavioural medicine interventions was solicited from content experts. The resulting list of index terms was used to generate a comprehensive search strategy to retrieve relevant records, and a thesaurus of terms with which to index them. The records are included in a register. A subset of records have been coded for study design, health condition, intervention, study participants, setting and provider and made available in a public online database. RESULTS: The Cochrane Behavioral Medicine Field database consists of over 3500 records of systematic reviews, meta-analyses and randomized controlled trials for public educational use. CONCLUSIONS: The register provides a comprehensive listing of studies relating to behavioural medicine interventions. The public online database enables easy access to the evidence base and provides enhanced details of the studies included on it. These databases are a valuable resource for the behavioural medicine community. Other fields are encouraged to duplicate these methods in the design of content-specific databases.  相似文献

OBJECTIVES: Our objectives were to identify literature on: (i) theory, evidence and gaps in knowledge relating to the help-seeking behaviour of people with learning disabilities and their carers; (ii) barriers experienced by people with learning disabilities in securing access to the full range of health services; (iii) interventions which improve access to health services by people with learning disabilities. DATA SOURCES: twenty-eight bibliographic databases, research registers, organizational websites or library catalogues; reference lists from identified studies; contact with experts; current awareness and contents alerting services in the area of learning disabilities. REVIEW METHODS: Inclusion criteria were English language literature from 1980 onwards, relating to people with learning disabilities of any age and all study designs. The main criteria for assessment was relevance to the Guilliford et al. model of access to health care (Gulliford et al. Access to health care. Report of a Scoping Exercise for the National Co-ordinating Centre for NHS Service Delivery and Organisation R & D (NCCSDO). London: NCCSDO, 2001), which was modified to the special needs of people with learning disabilities. Inclusion criteria focused on relevance to the model with initial criteria revised in light of literature identified and comments from a consultation exercise with people with learning disabilities, family and paid carers and experts in the field. Data abstraction was completed independently and selected studies were evaluated for scientific rigour and the results synthesized. RESULTS: In total, 2221 items were identified as potentially relevant and 82 studies fully evaluated. CONCLUSIONS: The process of identifying relevant literature was characterized by a process of clarifying the concept under investigation and sensitive search techniques which led to an initial over-identification of non-relevant records from database searches. Thesaurus terms were of limited value, forcing a reliance on using free-text terms and alternative methods of identifying literature to supplement and improve the recall of the database searches. A key enabler in identifying relevant literature was the depth and breadth of knowledge built up by the reviewers whilst engaged in this process.  相似文献

Objective:We aimed to determine overlaps and optimal combination of multiple database retrieval and citation tracking for evidence synthesis, based on a previously conducted scoping review on facilitators and barriers to implementing nurse-led interventions in dementia care.Methods:In our 2019 scoping review, we performed a comprehensive literature search in eight databases (CENTRAL, CINAHL, Embase, Emcare, MEDLINE, Ovid Nursing Database, PsycINFO, and Web of Science Core Collection) and used citation tracking. We retrospectively analyzed the coverage and overlap of 10,527 retrieved studies published between 2015 and 2019. To analyze database overlap, we used cross tables and multiple correspondence analysis (MCA).Results:Of the retrieved studies, 6,944 were duplicates and 3,583 were unique references. Using our search strategies, considerable overlaps can be found in some databases, such as between MEDLINE and Web of Science Core Collection or between CINAHL, Emcare, and PsycINFO. Searching MEDLINE, CINAHL, and Web of Science Core Collection and using citation tracking were necessary to retrieve all included studies of our scoping review.Conclusions:Our results can contribute to enhancing future search practice related to database selection in dementia care research. However, due to limited generalizability, researchers and librarians should carefully choose databases based on the research question. More research on optimal database retrieval in dementia care research is required for the development of methodological standards.  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

The amount of health information available on the Internet is considerable. In this context, several health gateways have been developed. Among them, CISMeF (Catalogue and Index of Health Resources in French) was designed to catalogue and index health resources in French. The goal of this article is to describe the various enhancements to the MeSH thesaurus developed by the CISMeF team to adapt this terminology to the broader field of health Internet resources instead of scientific articles for the medline bibliographic database. CISMeF uses two standard tools for organizing information: the MeSH thesaurus and several metadata element sets, in particular the Dublin Core metadata format. The heterogeneity of Internet health resources led the CISMeF team to enhance the MeSH thesaurus with the introduction of two new concepts, respectively, resource types and metaterms. CISMeF resource types are a generalization of the publication types of medline. A resource type describes the nature of the resource and MeSH keyword/qualifier pairs describe the subject of the resource. A metaterm is generally a medical specialty or a biological science, which has semantic links with one or more MeSH keywords, qualifiers and resource types. The CISMeF terminology is exploited for several tasks: resource indexing performed manually, resource categorization performed automatically, visualization and navigation through the concept hierarchies and information retrieval using the Doc'CISMeF search engine. The CISMeF health gateway uses several MeSH thesaurus enhancements to optimize information retrieval, hierarchy navigation and automatic indexing.  相似文献

Background: The researchers involved in this study work at Exeter Health library and at the Complementary Medicine Unit, Peninsula School of Medicine and Dentistry (PCMD). Within this collaborative environment it is possible to access the electronic resources of three institutions. This includes access to amed and other databases using different interfaces. Objectives: The aim of this study was to investigate whether searching different interfaces to the amed allied health and complementary medicine database produced the same results when using identical search terms. Methods: The following Internet‐based amed interfaces were searched: DIALOG DataStar; EBSCOhost and OVID SP_UI01.00.02. Search results from all three databases were saved in an endnote database to facilitate analysis. A checklist was also compiled comparing interface features. Results: In our initial search, DIALOG returned 29 hits, OVID 14 and Ebsco 8. If we assume that DIALOG returned 100% of potential hits, OVID initially returned only 48% of hits and EBSCOhost only 28%. In our search, a researcher using the Ebsco interface to carry out a simple search on amed would miss over 70% of possible search hits. Subsequent EBSCOhost searches on different subjects failed to find between 21 and 86% of the hits retrieved using the same keywords via DIALOG DataStar. In two cases, the simple EBSCOhost search failed to find any of the results found via DIALOG DataStar. Conclusions: Depending on the interface, the number of hits retrieved from the same database with the same simple search can vary dramatically. Some simple searches fail to retrieve a substantial percentage of citations. This may result in an uninformed literature review, research funding application or treatment intervention. In addition to ensuring that keywords, spelling and medical subject headings (MeSH) accurately reflect the nature of the search, database users should include wildcards and truncation and adapt their search strategy substantially to retrieve the maximum number of appropriate citations possible. Librarians should be aware of these differences when making purchasing decisions, carrying out literature searches and planning user education.  相似文献

Background: Complementary and alternative medicine (CAM) has succeeded to implement itself in the academic context of universities. In order to get information on CAM, clinicians, researchers and healthcare professionals as well as the lay public are increasingly turning to online portals and databases, which disseminate relevant resources. One specific type of online information retrieval systems, namely the database, is being reviewed in this article. Question: This overview aims at systematically retrieving and describing all databases covering the field of CAM. One of the requirements for inclusion was that the database would also have to be published in a medical journal. Data sources: The databases amed , CAMbase , embase , and medline /Pub Med were searched between December 2008 and December 2009 for publications relevant to CAM databases. The authors’ specialist library was also searched for grey literature to be included. Study selection: All included databases were then visited online and information on the context, structure and volume of the database was extracted. Main results: Forty‐five databases were included in this overview. Databases covered herbal therapies (n = 11), traditional Chinese medicine (n = 9) and some dealt with a vast number of CAM modalities (n = 9), amongst others. The amount of time the databases had been in existence ranged from 4 to 53 years. Countries of origin included the USA (n = 14), UK (n = 7) and Germany (n = 6), amongst others. The main language in 42 of 45 databases was English. Conclusions: Although this overview is quite comprehensive with respect to the field of CAM, certain CAM practices such as chiropractic, massage, reflexology, meditation or yoga may not have been covered adequately. A more detailed assessment of the quality of the included databases might give additional insights into the listed resources. The creation of a personalised meta‐search engine is suggested, towards which this overview could be seen as a first step.  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

Background: Leaders in the profession encourage academic health sciences librarians to assume new roles as part of the growth process for remaining vital professionals. Have librarians embraced these new roles?Objectives: This research sought to examine from the reference librarians'' viewpoints how their roles have changed over the past ten years and what the challenges these changes present as viewed by both the librarians and library directors.Method: A series of eight focus groups was conducted with reference librarians from private and public academic health sciences libraries. Directors of these libraries were interviewed separately.Results: Reference librarians'' activities have largely confirmed the role changes anticipated by their leaders. They are teaching more, engaging in outreach through liaison initiatives, and designing Web pages, in addition to providing traditional reference duties. Librarians offer insights into unanticipated issues encountered in each of these areas and offer some creative solutions. Directors discuss the issues from their unique perspective.Conclusion: Librarians have identified areas for focusing efforts in lifelong learning. Adult learning theory, specialized databases and resources needed by researchers, ever-evolving technology, and promotion and evaluation of the library are areas needing attention. Implications for library education and continuing professional development are presented.  相似文献

Background: Romania is a low‐income country of 22 million people and, currently, information regarding mental health research is limited. Romania is one of the last countries in eastern Europe not to have its own bibliographic biomedical database. Aim: To assess the content and quality of Romanian psychiatric research activity over time. Method: embase (1980 to April 2008), medline (1950 to April 2008) and Psyc INFO (1806 to April 2008) were systematically searched for psychiatric articles originating from Romania. The sample from Psyc INFO was described. Results: Psyc INFO was by far the best source of Romanian mental health literature with a considerable increase in the publication activity since 2000 (Psyc INFO identified 3236 hits, medline 549, embase 139). Most papers are in English, but a sizeable minority are in Romanian (30%), French (4%) or Hungarian (4%). The main topics of interest are cognitive processes, creativity, schizophrenia and cognitive development and stress and are, according to Psyc INFO’s indexing, ‘empirical studies’. Seventeen randomised trials were identified with all studies after 2000 being sponsored by industry. Conclusions: Surprisingly, and not in keeping with other studies of the literature of neighbouring countries, Psyc INFO is the major source of psychiatric bibliographic records of this region. There are signs of a resurgence of research activity in Romania and as the number of local mental health workers increases we can expect more output. Industry is now funding evaluative studies in Romania. As everywhere, but perhaps more acutely in situations of severely limited research support, there is a difficult balance to be struck between benefiting support and losing independence.  相似文献

This study compares six databases which contain information on applied and clinical human nutrition: AGRICOLA, BIOSIS, CAB ABSTRACTS, EMBASE, MEDLINE, and SCI-SEARCH. Five research questions were searched, and the results were compared to identify the database of first choice and to determine the degree of overlap among the databases. Results indicate that for most of the human nutrition questions searched, MEDLINE was the most productive database. However, MEDLINE alone only uncovered 24% to 69% of the citations available. A combination of MEDLINE and at least one other database is recommended. The results of this study suggest that for most human nutrition questions, AGRICOLA is the best file to complement MEDLINE.  相似文献
