The SMART Imagebase is a unique, educational resource for students, educators, library patrons, and professionals in healthcare and news media. 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. Of the individual databases, Embase had the highest overall recall (85.9%). 2016;5:39. For each review that we investigated, we determined what the recall was for all possible different database combinations of the most important databases. Of the 11 references included in this review, one was found only in Google Scholar and one only in Web of Science. Rethlefsen ML, Farrell AM, Osterhaus Trzasko LC, Brigham TJ.

Preston L, Carroll C, Gardois P, Paisley S, Kaltenthaler E. Syst Rev. 2 0 obj Prior research on database importance for systematic reviews has looked primarily at whether included references could have theoretically been found in a certain database, but most have been unable to ascertain whether the researchers actually found the articles in those databases [10, 12, 16, 17, 26]. 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 . Hold down the Ctrl key to select multiple options. We determined the databases that contributed most to the reviews by the number of unique references retrieved by each database used in the reviews. 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. Finding resources: MEDLINE. Please enable it to take advantage of the complete set of features! Depending on the goal of the search, different measures may be optimized. For a sample of 200 recently published systematic reviews, we calculated how many had used enough databases to ensure 95% recall. <> These could be retrieved by searching PubMed with the subset as supplied by publisher. We calculated the recall for individual databases and databases in all possible combination for all reviews included in the research. Library users and staff use WorldCat Discovery to search the WorldCat database of electronic, digital and physical resources; to identify materials they need and to find out where they are available. PubMed >/- 8CqD 0:J AT~Xr Bx:.}U_y>gEdUug1tXA ed! Some reviewers might accept a potential loss of 5% of relevant references; others would want to pursue 100% recall, no matter what cost. 2016 Feb 9;5:27. doi: 10.1186/s13643-016-0197-5. and transmitted securely. 2017. doi:10.1002/jrsm.1279. Privacy The other authors declare no competing interests. WB, JK, and OF designed the study. 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. ``6C~8 '* "r#=e ax A+ We assessed the frequency at which databases and combinations would achieve varying levels of recall (i.e., 95%). Based on the record numbers of the search results in EndNote, we determined from which database these references came. Over a third of the reviews were therapeutic, while slightly under a quarter answered an etiological question. 2008;14:4014. In general, we use the first 200 references as sorted in the relevance ranking of Google Scholar. However, for one review of this domain, the recall was 82%. Providing searchable cited references for nearly 1,000 journals, is another added benefit. Note: Putting quotation marks around phrases tells the database to search for these words as a phrase and not as individual words. [10] and van Enst et al. 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. mOkV1#8 (uTb Click in the check box below Research Article to select this option. These are mostly unique PubMed references, which are not assigned MeSH terms, and are often freely available via PubMed Central. 2015;68:107684. The three databases were searched for citations on topics selected by three nurse researchers and the results were compared. Please note: Selecting permissions does not provide access to the full text of the article, please see our help page The other study from the Journal of Advanced Nursing is indexed in MEDLINE and Embase but was only retrieved because of the addition of KeyWords Plus in Web of Science. Phys Ther. The references to these reviews can be found in Additional file 1. The Cochrane Handbook recommends searching MEDLINE, Cochrane CENTRAL, and Embase for systematic reviews of RCTs. 2015;10:5068. Due to the nature and distribution of the nursing literature, it is especially important for the searcher to understand and respond to the focus of the researcher. There is an overlap in the journals indexed by these two databases. The database includes all charts, diagrams, graphs, tables, photos, and other graphical elements essential to medical research. 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. One hundred and fifty-nine journals are uniquely indexed in BNI compared with the basic version of CINAHL. Ahmadi M, Ershad-Sarabi R, Jamshidiorak R, Bahaodini K. Comparison of bibliographic databases in retrieving information on telemedicine. Ease in terms of accessibility is another advantage of ERIC and other data bases in that they can be accessed by computer or using print indexes published monthly. Michaleff ZA, Costa LO, Moseley AM, Maher CG, Elkins MR, Herbert RD, Sherrington C. CENTRAL, PEDro, PubMed, and EMBASE are the most comprehensive databases indexing randomized controlled trials of physical therapy interventions. The sum of all these values is the total probability of acceptable recall in the random sample. ?lq!9!OW$2w1tp=/0 0aPz6Kx|M}97_jn{oy0@o65I>KrjPov= D@H?z`. 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.

The content is solely the responsibility of the authors and does not necessarily represent the official views of the National Institutes of Health. Once validated and certified for inclusion, these OA journals are treated with high-quality subject indexing and sophisticated, precise/accurate full-text linking. The comparative recall of Google Scholar versus PubMed in identical searches for biomedical systematic reviews: a review of searches used in systematic reviews. The median % of unique studies was 9.09 %; while the range had a lowest value of 5.0 % to the highest value of 33.0 %. To compare our practice of database usage in systematic reviews against current practice as evidenced in the literature, we analyzed a set of 200 recent systematic reviews from PubMed. On this page you will learn how to limit your results in CINAHL to: 2019 Aug;21(4):853-878. doi: 10.1007/s10903-018-0816-4. That is with the generous assumption that the searches in those databases had been designed sensitively enough. If this resulted in extraneous results, the search was subsequently limited using a distinct part of the title or a second author name. Figure1 shows the percentages of reviews where a certain database combination led to a certain recall. In addition, Michaleff et al. Manage cookies/Do not sell my data we use in the preference centre. J Med Libr Assoc. stream A total of 292 (17%) references were found by only one database. This implies that 17% of the reviews in the PubMed sample would have achieved an acceptable recall of 95%. Bramer WM, Giustini D, Kramer BM, Anderson PF. 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. 2011;91:1907. BMC Med Inform Decis Mak. Starting with the most recent articles, we determined the databases searched either from the abstract or from the full text until we had data for 200 reviews. endobj CAUTION Do not use Linked Full Text Limit. For nine of these reviews, all the studies that had been included in the final synthesis were available in the CINAHL database, so it could have been possible to identify all the included studies using just this one database, while for an additional 21 reviews (49 %), 80 % or more of the included studies were available in CINAHL. 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. Res Synth Methods. The purpose of this research was to determine which of three databases, CINAHL, EMBASE or MEDLINE, should be accessed when researching nursing topics. The calculation is shown in Table5. Health Inf Libr J. Lastly, access to databases is often limited and only available on subscription basis. Select an option by finding it in the list and clicking on it (it will then be highlighted). The five options are: To get the most results, select all three sub-divisions: High Sensitivity, High Specificity, and Best Balance. https://doi.org/10.1186/s13643-017-0644-y, DOI: https://doi.org/10.1186/s13643-017-0644-y. 2005 Jan 8;5:2. doi: 10.1186/1471-2288-5-2. Case studies may be prospective (in which criteria are established and cases fitting the criteria are included as they become available) or retrospective (in which criteria are established and cases are selected from historical records for inclusion in the study). Searching additional databases except PubMed are necessary for a systematic review. 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. Embase and MEDLINE combined with either Google Scholar or Web of Science scored similarly well on overall recall (95.9%). Of the five reviews that included only RCTs, four reached 100% recall if MEDLINE, Web of Science, and Google Scholar combined were complemented with Cochrane CENTRAL. 2005;51:8489. Wichor M. Bramer. Halladay CW, Trikalinos TA, Schmid IT, Schmid CH, Dahabreh IJ. Federal government websites often end in .gov or .mil. Disadvantages of using CINAHL There really aren't any, except that it's just a single database, and you might miss material that is available elsewhere. The search on substance abuse in pregnancy, not restricted to nursing literature, retrieved better results when searching both MEDLINE and EMBASE. MedicLatinais a unique collection of medical research and investigatory journals from renowned Latin American and Spanish publishers. 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. Librarian co-authors correlated with higher quality reported search strategies in general internal medicine systematic reviews. Of course, the loss of a minor non-randomized included study that follows the systematic reviews conclusions would not be as problematic as losing a major included randomized controlled trial with contradictory results. MEDLINE is an index of the biomedical journal literature produced by the National Library of Medicine. MEDLINE did find unique references that had not been found in Embase, although our searches in Embase included all MEDLINE records. All authors have approved the final manuscript. Disadvantages of Databases 1. 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. Searching only Embase produced an NNR of 57 on average, whereas, for the optimal combination of four databases, the NNR was 73. We estimate that 60% of published systematic reviews do not retrieve 95% of all available relevant references as many fail to search important databases. The recall of the database combinations was calculated over all included references retrieved by any database. Google Scholar. <> Provided by the Springer Nature SharedIt content-sharing initiative. Consequently . The reviews covered a wide variety of disease, none of which was present in more than 12% of the reviews. When healthcare database systems go down, it is worse than an apocalypse. The X-axis represents the percentage of reviews for which a specific combination of databases, as shown on the y-axis, reached a certain recall (represented with bar colors). 1 0 obj 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. Bramer, W.M., Rethlefsen, M.L., Kleijnen, J. et al. In general, searches are developed in MEDLINE in Ovid (Ovid MEDLINE In-Process & Other Non-Indexed Citations, Ovid MEDLINE Daily and Ovid MEDLINE, from 1946); Embase.com (searching both Embase and MEDLINE records, with full coverage including Embase Classic); the Cochrane Central Register of Controlled Trials (CENTRAL) via the Wiley Interface; Web of Science Core Collection (hereafter called Web of Science); PubMed restricting to records in the subset as supplied by publisher to find references that not yet indexed in MEDLINE (using the syntax publisher [sb]); and Google Scholar. Embase retrieved the most unique included references, followed by MEDLINE, Web of Science, and Google Scholar. Improvement of precision was calculated as the ratio between the original precision from the searches in all databases and the precision for each database and combination. The researchers that requested the search received a deduplicated EndNote file from which they selected the references relevant for inclusion in their systematic review. ProQuest Nursing & Allied Health Source provides abstracting and indexing for more than 1,050 titles, with over 875 titles in full-text, plus more than 12,300 full text dissertations representing the most rigorous scholarship in nursing and related fields. From the published journal article, we extracted the list of final included references. Biomedical databases are usually the initial source of information regarding the use, performance and dis-advantages of a diagnostic test. (DOCX 19kb). andy gibb last interview. Scroll down the page below the search boxes to locate these filters or limiters. . Percentage of systematic reviewsof a certain domainfor which the combination Embase, MEDLINE and Cochrane CENTRAL reached a certain recall. In 12 reviews (52%), Scopus retrieved 100% of all included references retrieved by Embase or Web of Science. 1996 Jul;84(3):402-8. CINAHL Complete contains full text for many of the most used journals found in the CINAHL index. scott burns lincoln ventures.
