Identify resources at your library and in the collections of the worlds libraries. For all individual databases or combinations of the four important databases from our research (MEDLINE, Embase, Web of Science, and Google Scholar), we multiplied the frequency of occurrence of that combination in the random set, with the probability we found in our research that this combination would lead to an acceptable recall of 95%. 2005;93:7480. Based on these calculations, we estimate that the probability that this random set of reviews retrieved more than 95% of all possible included references was 40%. Abbreviations: EM Embase, ML MEDLINE, WoS Web of Science, GS Google Scholar. BMC Med Res Methodol. [17] found the added value of other databases only for newer, non-indexed references.

Differences in thesaurus terms between databases add another significant burden for translation. At Erasmus MC, search strategies for systematic reviews are often designed via a librarian-mediated search service. Are MEDLINE searches sufficient for systematic reviews and meta-analyses of the diagnostic accuracy of depression screening tools?

Preston L, Carroll C, Gardois P, Paisley S, Kaltenthaler E. Syst Rev. However, searching databases is laborious and time-consuming, as syntax of search strategies are database specific. A comparison of the performance of seven key bibliographic databases in identifying all relevant systematic reviews of interventions for hypertension. However, when looking at individual reviews, the probability of missing more than 5% of included references found through database searching is 33% when Google Scholar is used together with Embase and MEDLINE and 30% for the Web of Science, Embase, and MEDLINE combination. PubMed PubMed is a much larger database than CINAHL, but CINAHL emphasizes nursing and the allied health disciplines. We estimate that 60% of published systematic reviews do not retrieve 95% of all available relevant references as many fail to search important databases. Moreover, in combinations where the number of results was greatly reduced, the recall of included references was lower. Where should the pharmacy researcher look first? Perfect for researchers at all levels, this comprehensive consumer health resource provides authoritative information on the full range of health-related issues, from current disease and disorder information to in-depth coverage of alternative medical practices. 4 and 5. Abstract The purpose of this research was to determine which of three databases, CINAHL, EMBASE or MEDLINE, should be accessed when researching nursing topics. Asterisk indicates that the recall of all databases has been calculated over all included references. Jz9+]J,y92Nt,t\9/FK:> ).{Qf3PSrPaU>`Pn8e==rIvyFAA-qYB6B )lYUIJa)se2*O:+6XLe[S =d^J>]b=\qf'9E%L`DS_.A\yX For example, around a third of the reviews (37%) relied on the combination of MEDLINE and Embase. Is the coverage of Google Scholar enough to be used alone for systematic reviews. Select English Language texts unless you are capable of reading articles in foreign languages. The sum of all these values is the total probability of acceptable recall in the random sample. We are not implying that a combined search of the four recommended databases will never result in relevant references being missed, rather that failure to search any one of these four databases will likely lead to relevant references being missed. WB drafted the first manuscript, which was revised critically by the other authors.

For each review that we investigated, we determined what the recall was for all possible different database combinations of the most important databases. f~C>j)Kx8t>qi0@fWT. 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. The purpose of this research was to determine which of three databases, CINAHL, EMBASE or MEDLINE, should be accessed when researching nursing topics. The purpose of this research was to determine which of three databases, CINAHL, EMBASE or MEDLINE, should be accessed when researching nursing topics. This can be offset, as noted above, by going to the EBSCOhost (Health) package of databases. Nursing: Indexes & Databases. While previous studies determined the coverage of databases, we analyzed the actual retrieval from the original searches for systematic reviews. See Fig. See Table1 for definitions of these measures. J Clin Epidemiol. Investigators and information specialists searching for relevant references for a systematic review (SR) are generally advised to search multiple databases and to use additional methods to be able to adequately identify all literature related to the topic of interest [1,2,3,4,5,6]. ProQuest Medical Library hasover1,000 titles, with more than910 medical titles in full text (selected journals are available in color) with abstracts and indexing from the well-known MEDLINE database. Fifty one of the 81 titles . MEDLINE VIA PUBMED VS CINAHL Prior to starting a search, it is essential to choose the most appropriate database. 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. WB and ML analyzed the data. The three databases were searched for citations on topics selected by three nurse researchers and the results were compared. 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 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.

To identify whether our searches had found the included references, and if so, from which database(s) that citation was retrieved, each included reference was located in the original corresponding EndNote library using the first author name combined with the publication year as a search term for each specific relevant publication. Disclaimer. Wilkins T, Gillies RA, Davies K. EMBASE versus MEDLINE for family medicine searches: can MEDLINE searches find the forest or a tree? Other databases that we identified as essential for good recall were searched much less frequently; Embase was searched in 61% and Web of Science in 35%, and Google Scholar was only used in 10% of all reviews.
