Would you like email updates of new search results? 4 0 obj This study also highlights once more that searching databases alone is, nevertheless, not enough to retrieve all relevant references. [26] found that Cochrane CENTRAL included 95% of all RCTs included in the reviews investigated. Depending on the goal of the search, different measures may be optimized. Google Scholar. There is an overlap in the journals indexed by these two databases. It is laborious for searchers to translate a search strategy into multiple interfaces and search syntaxes, as field codes and proximity operators differ between interfaces. Objective: To review the literature on the benefits and disadvantages of clinical and medical audit, and to assess the main facilitators and barriers to conducting the audit process. For a sample of 200 recently published systematic reviews, we calculated how many had used enough databases to ensure 95% recall. For example, in 48% of all systematic reviews, the combination of Embase and MEDLINE (with or without Cochrane CENTRAL; Cochrane CENTRAL did not add unique relevant references) reaches a recall of at least 95%. sharing sensitive information, make sure youre on a federal For all individual reviews, we determined the median recall, the minimum recall, and the percentage of reviews for which each single database or combination retrieved 100% recall. kON0=ArP35x`*[r(DYVBa9BJ2w\LueOJ=i.dR;mmP/P ThePsycINFO renowned resource for abstracts of scholarly journal articles, book chapters, books, and dissertations, is the largest resource devoted to peer-reviewed literature in behavioral science and mental health. Optimal database combinations for literature searches in systematic reviews: a prospective exploratory study, https://doi.org/10.1186/s13643-017-0644-y, http://creativecommons.org/licenses/by/4.0/, http://creativecommons.org/publicdomain/zero/1.0/. Of the individual databases, Embase had the highest overall recall (85.9%). In general, we use the first 200 references as sorted in the relevance ranking of Google Scholar. Performance was measured using recall, precision, and number needed to read. This Spanish language database contains full text for 130 peer-reviewed medical journals in native Spanish. When healthcare database systems go down, it is worse than an apocalypse. &Jl1/>nw\CCX=prz Dcr8UBW3L`Du8*r (+P/:SXQB^ In contrast, searching too many databases has clear disadvantages, as the search strategy must be translated to fit different databases using different interfaces and search syntaxes, and the. The https:// ensures that you are connecting to the Cochrane CENTRAL is absent from the table, as for the five reviews limited to randomized trials, it did not add any unique included references. Within systematic reviews, when searching for relevant references, it is advisable to use multiple databases. Sixteen percent of the included references (291 articles) were only found in a single database; Embase produced the most unique references (n=132). The databases avail-able include the Cochrane Collaboration, Medline (in various forms such as PubMed), Best Evidence10and Embase.The most widely used and most often recom-mended database isMedline. What is lost when searching only one literature database for articles relevant to injury prevention and safety promotion? From the published journal article, we extracted the list of final included references. There are also fewer of them, and they can be harder to find. J Clin Epidemiol. In that case, Google Scholar might add value by searching the full text of articles. Other specialized databases, such as CINAHL or PsycINFO, add unique references to some reviews where the topic of the review is related to the focus of the database. We documented the department of the first author. 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. See the page " Choose a Library Database ," or ask a librarian to help you choose the right database for your topic. The other authors declare no competing interests. Beckles Z, Glover S, Ashe J, Stockton S, Boynton J, Lai R, Alderson P. Searching CINAHL did not add value to clinical questions posed in NICE guidelines.

Levay P, Raynor M, Tuvey D. The contributions of MEDLINE, other bibliographic databases and various search techniques to NICE public health guidance. Of the 11 references included in this review, one was found only in Google Scholar and one only in Web of Science. Note: Putting quotation marks around phrases tells the database to search for these words as a phrase and not as individual words. 1990;23:58393. It is likely that topical differences in systematic reviews may impact whether databases such as Web of Science and Google Scholar add value to the review. The researchers that requested the search received a deduplicated EndNote file from which they selected the references relevant for inclusion in their systematic review. 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. All authors have approved the final manuscript. One hundred and fifty-nine journals are uniquely indexed in BNI compared with the basic version of CINAHL.

A systematic approach to searching: how to perform high quality literature searches more efficiently. ; ; If the research question is more interdisciplinary, a broader science database such as Web of Science is likely to add value. Stevinson C, Lawlor DA. Unable to load your collection due to an error, Unable to load your delegates due to an error. In short, the method consists of an efficient way to combine thesaurus terms and title/abstract terms into a single line search strategy. Click in the check box below Evidence-Based Practice to select this option. Nevertheless others have concluded that a single database is not sufficient to retrieve all references for systematic reviews [18, 19]. Fifty one of the 81 titles . J Clin Epidemiol. Lemeshow AR, Blum RE, Berlin JA, Stoto MA, Colditz GA. Searching one or two databases was insufficient for meta-analysis of observational studies. Article The sum of all these values is the total probability of acceptable recall in the random sample. Journal coverage, which spans from the 1800s to present, includes international material selected from around 2,400 periodicals in dozens of languages. McGowan J, Sampson M. Systematic reviews need systematic searchers. There are disadvantages to using multiple databases. Clipboard, Search History, and several other advanced features are temporarily unavailable. Even when taking into account that many searchers consider the use of Scopus as a replacement of Embase, plus taking into account the large overlap of Scopus and Web of Science, this estimate remains similar. By using this website, you agree to our The purpose of this research was to determine which of three databases, CINAHL, EMBASE or MEDLINE, should be accessed when researching nursing topics. Unauthorized use of these marks is strictly prohibited. Whether Embase and Web of Science can be replaced by Scopus remains uncertain. Table3 displays the number of unique results retrieved for each single database. In this case, the number of hits from Google Scholar was limited to 100. Syst Rev.

Our study shows that, to reach maximum recall, searches in systematic reviews ought to include a combination of databases. Hold down the Ctrl key to select multiple options. MEDLINE did find unique references that had not been found in Embase, although our searches in Embase included all MEDLINE records. Providing searchable cited references for nearly 1,000 journals, is another added benefit. LearningExpress Library features nearly 1,000 online tutorials, practice tests, and eBooks to help patrons of all ages. 2006 Jul;59(7):710-4. doi: 10.1016/j.jclinepi.2005.09.013. PubMed does not. 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. Asterisk indicates that the recall of all databases has been calculated over all included references. This implies that 17% of the reviews in the PubMed sample would have achieved an acceptable recall of 95%. Subject-specific databases such as CINAHL, PsycINFO, and SportDiscus only retrieved additional included references when the topic of the review was directly related to their special content, respectively nursing, psychiatry, and sports medicine. Ignoring one or more of the databases that we identified as the four key databases will result in more precise searches with a lower number of results, but the researchers should decide whether that is worth the >increased probability of losing relevant references. Together, these reviews included a total of 1830 references. https://doi.org/10.1186/s13643-017-0644-y, DOI: https://doi.org/10.1186/s13643-017-0644-y. 2011. In our analyses, we combined the results from MEDLINE in Ovid and PubMed (the subset as supplied by publisher) into one database labeled MEDLINE. The searcher in the case of all 58 systematic reviews is an experienced biomedical information specialist. We analyzed whether the added value of Web of Science and Google Scholar was dependent of the domain of the review. 11 reviews, where we were able to recheck all the databases used by the original review authors, had included a study that was uniquely identified from the CINAHL database. One explanation for our finding may be that if the research question is very specific, the topic of research might not always be mentioned in the title and/or abstract. The higher recall from adding extra databases came at a cost in number needed to read (NNR). For reviews in our study that included RCTs only, indeed, this recommendation was sufficient for four (80%) of the reviews. Using that combination, 93% of the systematic reviews in our study obtained levels of recall that could be considered acceptable (>95%).

The highest scoring database combination without Embase is a combination of MEDLINE, Web of Science, and Google Scholar, but that reaches satisfactory recall for only 39% of all investigated systematic reviews, while still requiring a paid subscription to Web of Science. CINAHL contains many systematic reviews published in journals. Complement Ther Med. "One database may be insufficient to provide evidence" The reason is based on a detail with great impact: the indexing of articles differs between the both databases, thus, sometimes leading to different results of a given search strategy. Res Synth Methods. Google Scholar. Articles that are indexed with a set of identified thesaurus terms, but do not contain the current search terms in title or abstract, are screened to discover potential new terms. : //doi.org/10.1186/s13643-017-0644-y research question is more interdisciplinary, a broader Science database such as Web Science!, and number needed to read down the Ctrl key to select multiple options syntaxes.
