We documented the department of the first author. MeSH The aim of our research is to determine the combination of databases needed for systematic review searches to provide efficient results (i.e., to minimize the burden for the investigators without reducing the validity of the research by missing relevant references). &Jl1/>nw\CCX=prz Dcr8UBW3L`Du8*r (+P/:SXQB^ Though we occasionally used the regional databases LILACS and SciELO in our reviews, they did not provide unique references in our study. Journal coverage, which spans from the 1800s to present, includes international material selected from around 2,400 periodicals in dozens of languages. However, for one review of this domain, the recall was 82%. In addition to journal articles, CINAHL includes books, book chapters, dissertations, and computer programs. Handwashing OR "Hand Washing" OR "Hand Rubs" OR "Hand Disinfection". Comparing International Pharmaceutical Abstracts and MEDLINE. It therefore finds articles in which the topic of research is not mentioned in title, abstract, or thesaurus terms, but where the concepts are only discussed in the full text.

Lastly, we checked whether the reviews described limiting their included references to a particular study design. J Med Libr Assoc. What is considered acceptable recall for systematic review searches is open for debate and can differ between individuals and groups. Bramer WM, Rethlefsen ML, Mast F, Kleijnen J. Asterisk indicates that the recall of all databases has been calculated over all included references. endobj Ahntastic Adventures in Silicon Valley Comparing the coverage, recall, and precision of searches for 120 systematic reviews in Embase, MEDLINE, and Google Scholar: a prospective study. It is likely caused by difference in thesaurus terms that were added, but further analysis would be required to determine reasons for not finding the MEDLINE records in Embase. This is the world's largest full text psychology database offering full text coverage for nearly 400 journals. This number however is not an answer to the question of a researcher performing a systematic review, regarding which databases should be searched. Federal government websites often end in .gov or .mil. The Web of Science database is considered a preferred data source for bibliometric analysis due to the comprehensive information and multi-disciplinary data of literature provided (Falagas et al . Almost all reviews (97%) reported a search in MEDLINE. Article A secondary aim is to investigate the current practice of databases searched for published reviews. stream The calculation is shown in Table5. Most reviews did not limit to certain study designs, 9% limited to RCTs only, and another 9% limited to other study types. An official website of the United States government. Bramer WM, Giustini D, Kramer BM, Anderson PF. Once you have set up your search, here is how you can limit your results to only case studies: CINAHL Plus with Full Text offers a number of filters or limiters that can help you find only specific types of studies. To categorize the types of patient/population and intervention, we identified broad MeSH terms relating to the most important disease and intervention discussed in the article. Subirana M, Sol I, Garcia JM, Gich I, Urrtia G. J Clin Epidemiol. New candidate terms are added to the basic search and evaluated. Higgins JPT, Green S. Cochrane handbook for systematic reviews of interventions: The Cochrane Collaboration, London, United Kingdom. Because this is a novel finding, we cannot conclude whether it is due to our dataset or to a generalizable principle. In both these reviews, the topic was highly related to the topic of the database. In that case, Google Scholar might add value by searching the full text of articles. A nursing qualitative systematic review required MEDLINE and CINAHL for study identification. Consequently . 2015;10:5068. Are included references being missed because the review authors failed to search a certain database? 3 0 obj PubMed Lawrence DW. Figure4 shows the distribution of this value for individual reviews. For example, in the, Scroll down the page below the search boxes until you find the, Scroll down the page below the search boxes until you see. 2 0 obj Future research should continue to investigate recall of actual searches beyond coverage of databases and should consider focusing on the most optimal database combinations, not on single databases. [17] found the added value of other databases only for newer, non-indexed references. PubMed BMC Med Res Methodol. We did not investigate whether the loss of certain references had resulted in changes to the conclusion of the reviews. Health Inf Libr J. is uptodate category 1 cme for physician assistants; pros and cons of cinahl database Meta. They are usually one of the easiest study types to find in any nursing or medical database. The purpose of this research was to determine which of three databases, CINAHL, EMBASE or MEDLINE, should be accessed when researching nursing topics. :p#("-!r>5"@5Ip^P|~1zsqE- @QK We estimate more than 50% of reviews that include more study types than RCTs would miss more than 5% of included references if only traditional combination of MEDLINE, Embase, and Cochrane CENTAL is searched. There are disadvantages to using multiple databases. The major strength of our paper is that it is the first large-scale study we know of to assess database performance for systematic reviews using prospectively collected data. Whether Embase and Web of Science can be replaced by Scopus remains uncertain. BMC Med Res Methodol. Since these studies have a long-term component, they promote abetter quality of evidence than a shorter study. Improving search efficiency for systematic reviews of diagnostic test accuracy: an exploratory study to assess the viability of limiting to MEDLINE, EMBASE and reference checking. We've already shown how to use this limiter for systematic reviews and case studies; other useful publication types for evidence-based practice include Clinical Trial and Meta Analysis. Systematic Reviews Until 2016, the most complete MEDLINE selection in Ovid still lacked the electronic publications that were already available in PubMed. The combination of Embase, MEDLINE, Web of Science Core Collection, and Google Scholar performed best, achieving an overall recall of 98.3 and 100% recall in 72% of systematic reviews. Sixteen percent of the included references (291 articles) were only found in a single database; Embase produced the most unique references (n=132). Searching additional databases except PubMed are necessary for a systematic review. For all but one domain, the traditional combination of Embase, MEDLINE, and Cochrane CENTRAL did not retrieve enough included references. Exploring the 'Patient Experience' of Individuals with Limited English Proficiency: A Scoping Review. disadvantages of cinahl database. A comparative study of clinical end-user and librarian searches. This search was used in earlier research [21]. Ross-White A, Godfrey C. Is there an optimum number needed to retrieve to justify inclusion of a database in a systematic review search? Systematic review searchers should consider using these databases if they are available to them, and if their institution lacks availability, they should ask other institutes to cooperate on their systematic review searches. FOIA Using that combination, 93% of the systematic reviews in our study obtained levels of recall that could be considered acceptable (>95%). 2005 Jan 8;5:2. doi: 10.1186/1471-2288-5-2. This implies that 17% of the reviews in the PubMed sample would have achieved an acceptable recall of 95%. . Those databases that contributed the most unique included references were then considered candidate databases to determine the most optimal combination of databases in the further analyses. Our experience has shown us that it is also impacted by the ability of the searcher, the accuracy of indexing of the database, and the complexity of terminology in a particular field. We calculated the ratio between the number of results found when searching all databases, including databases not included in our analyses, such as Scopus, PsycINFO, and CINAHL, and the number of results found searching a selection of databases. The Cochrane Handbook, for example, recommends the use of at least MEDLINE and Cochrane Central and, when available, Embase for identifying reports of randomized controlled trials [7]. 2008;39:e139. Moreover, in combinations where the number of results was greatly reduced, the recall of included references was lower. 2016;16:113. The three databases were searched for citations on topics selected by three nurse researchers and the results were compared. PubMed Central (PMC) is a free full-text archive of biomedical and life sciences journal literature at the U.S. National Institutes of Health's National Library of Medicine (NIH/NLM). This limiter box allows you to select specific article types. We copied from the MeSH tree the top MeSH term directly below the disease category or, in to case of the intervention, directly below the therapeutics MeSH term. Disadvantages of Databases 1. Of the 11 references included in this review, one was found only in Google Scholar and one only in Web of Science. National Library of Medicine Before Article Mental Measurements Yearbook,produced by the Buros Institute at the University of Nebraska, provides users with a comprehensive guide to over 2,700 contemporary testing instruments. Some of the remaining reviews explored patient experience of conditions including heart failure, diabetes, respiratory tract infections while others investigated patient experience of healthcare interventions such as anti-depressants, occupational therapy or palliative care. The CINAHL Plus with Full Text database is an unfiltered database containing over 750 nursing and allied health related journals, and indexes another 5,000. Searching Google Scholar is challenging as it lacks basic functionality of traditional bibliographic databases, such as truncation (word stemming), proximity operators, the use of parentheses, and a search history. The three databases were searched for citations on topics selected by three nurse researchers and the results were compared. %PDF-1.5 However, the wide range of scope, topic, and criteria between systematic reviews and their related review types make it very hard to answer this question.
