Our conclusion that Web of Science and Google Scholar are needed for completeness has not been shared by previous research. andy gibb last interview. j 'o This happens, particularly with lesser-used medications and treatments. Based on these, we determined the percentage of reviews where that database combination had achieved 100% recall, more than 95%, more than 90%, and more than 80%. Size 2015;68:107684. Can Fam Physician. 2011;91:1907. To our surprise, Cochrane CENTRAL did not identify any unique included studies that had not been retrieved by the other databases, not even for the five reviews focusing entirely on RCTs. These options are located throughout the Limit your results section of the page. Comput Biomed Res.

The third key database we identified in this research, Web of Science, is only mentioned as a citation index in the Cochrane Handbook, not as a bibliographic database. Using similar calculations, also shown in Table5, we estimated the probability that 100% of relevant references were retrieved is 23%. 2016;16:113. Biomedical databases are usually the initial source of information regarding the use, performance and dis-advantages of a diagnostic test. 1 0 obj
Once you have set up your search, here is how you can limit your results to only randomized controlled trials: Cohort studies are a type of longitudinal study, or observational study, that analyze risk factors by following groups that share a common characteristic or experience over time. These are mostly unique PubMed references, which are not assigned MeSH terms, and are often freely available via PubMed Central. Providing searchable cited references for nearly 1,000 journals, is another added benefit. 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. That is with the generous assumption that the searches in those databases had been designed sensitively enough. Asterisk indicates that the recall of all databases has been calculated over all included references. A nursing qualitative systematic review required MEDLINE and CINAHL for study identification. Cited by lists all citing articles based on Crossref citations.Articles with the Crossref icon will open in a new tab. Accessibility Health Source: Nursing/Academic Editionalso features theLexi-PAL Drug Guide,which covers 1,300 generic drug patient education sheets with more than 4,700 brand names. https://doi.org/10.1186/s13643-017-0644-y, DOI: https://doi.org/10.1186/s13643-017-0644-y. Disadvantages of Databases 1. Of the combinations of two databases, Embase and MEDLINE had the best results (92.8%). Thirty-seven references were found in MEDLINE (Ovid) but were not available in Embase.com. If this resulted in extraneous results, the search was subsequently limited using a distinct part of the title or a second author name. Inj Prev. Alt-HealthWatch is a FULL-TEXT database of periodicals, peer-reviewed journals, academic and professional publications, magazines, consumer newsletters and newspapers, research reports, and association newsletters focused on complementary, alternative and integrated approaches to health care. However, whether an article is present in a database may not translate to being found by a search in that database. 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. Click in the check box below Research Article to select this option. The information specialists of Erasmus MC developed an efficient method that helps them perform searches in many databases in a much shorter time than other methods. mOkV1#8 (uTb @mR]L#-wbtR5Q Provided by the Springer Nature SharedIt content-sharing initiative. If Erasmus MC authors had conducted more reviews that included only RCTs, Cochrane CENTRAL might have added more unique references. All authors have approved the final manuscript. 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.

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. Using the prospectively recorded results and the studies included in the publications, we calculated recall, precision, and number needed to read for single databases and databases in combination. 2 -

Some concluded that searching only one database can be sufficient as searching other databases has no effect on the outcome [16, 17]. J Clin Epidemiol. 2016;5:39. However, for one review of this domain, the recall was 82%. An overview of the broad topical categories covered in these reviews is given in Table2. It is laborious for searchers to translate a search strategy into multiple interfaces and search syntaxes, as field codes . Melissa Rethlefsen receives funding in part from the National Center for Advancing Translational Sciences of the National Institutes of Health under Award Number UL1TR001067. 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%. Published reviews were included if the search strategies and results had been documented at the time of the last update and if, at minimum, the databases Embase, MEDLINE, Cochrane CENTRAL, Web of Science, and Google Scholar had been used in the review. Bramer WM, Giustini D, Kramer BMR. 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. J Clin Epidemiol. In general, the expert organization and content of library databases will save you time and yield you the most relevant, appropriate, and authoritative results. The complete results from all databases used for each of the systematic reviews were imported into a unique EndNote library upon search completion and saved without deduplication for this research. References to the systematic reviews published by Erasmus MC authors that were included in the research. Previous studies have investigated the added value of different databases on different topics [8,9,10,11,12,13,14,15]. 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. If an included reference was not found in the EndNote file, we presumed the authors used an alternative method of identifying the reference (e.g., examining cited references, contacting prominent authors, or searching gray literature), and we did not include it in our analysis. 2008;39:e139. Percentage of systematic reviewsof a certain domainfor which the combination Embase, MEDLINE and Cochrane CENTRAL reached a certain recall. Figure1 shows the percentages of reviews where a certain database combination led to a certain recall. The one review where it was insufficient was about alternative medicine, specifically meditation and relaxation therapy, where one of the missed studies was published in the Indian Journal of Positive Psychology. PubMed This can be offset, as noted above, by going to the EBSCOhost (Health) package of databases. 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. 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. Many of the reviews were initiated by members of the departments of surgery and epidemiology. Nursing & Allied Health SourceTM provides users with reliable healthcare information covering nursing, allied health, alternative and complementary medicine. This research goes beyond retrospectively assessed coverage to investigate real search performance in databases. 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. All searches in this study were developed and executed by W.M.B. 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. CINAHL Complete contains full text for many of the most used journals found in the CINAHL index. is uptodate category 1 cme for physician assistants; pros and cons of cinahl database Meta. WB and ML analyzed the data. 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. Cookies policy. The skills and experience of the searcher are one of the most important aspects in the effectiveness of systematic review search strategies [23,24,25]. NOTE There are many limiters that we haven't covered. Created by the National Library of Medicine,MEDLINEuses MeSH (Medical Subject Headings) indexing with tree, tree hierarchy, subheadings and explosion capabilities to search citations from over 4,800 current biomedical journals. The ratio between number of results per database combination and the total number of results for all databases, The ratio between precision per database combination and the total precision for all databases. 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. Although we did not use these special topic databases in all of our reviews, given the low number of reviews where these databases added relevant references, and observing the special topics of those reviews, we suggest that these subject databases will only add value if the topic is related to the topic of the database.

J Clin Epidemiol. Unique results from specialized databases that closely match systematic review topics, such as PsycINFO for reviews in the fields of behavioral sciences and mental health or CINAHL for reviews on the topics of nursing or allied health, indicate that specialized databases should be used additionally when appropriate. x]Y~w_R%l@$RI[{odf]y4OH ]C|hpt_m/xt>ov\rxl_ g,)#5|wd=SO'^=I.zZ~|YJ2"%cVK^Ir~PNluRn-2B nlVy*/Us>-|\ .a-=/l :s#C&xdyu3Di*e"ySHs=?7i For four out of five systematic reviews that limited to randomized controlled trials (RCTs) only, the traditional combination retrieved 100% of all included references.
