Comparing the coverage, recall, and precision of searches for 120 systematic reviews in Embase, MEDLINE, and Google Scholar: a prospective study. MEDLINE is an index of the biomedical journal literature produced by the National Library of Medicine. FOIA The database combinations with the highest recall did not reduce the total number of results by large margins. CINAHL indexing terms and policies reflect a more general approach and the index term "diagnosis," when exploded (ie, when all subdivisions of the indexed term are retrieved), covers most aspects of nursing assessment, screening (people with no symptoms or indications of disease), and diagnosis (people with symptoms or conditions suggestive of % WB and ML analyzed the data. A systematic approach to searching: how to perform high quality literature searches more efficiently. 2013 Jan 9;13:7. doi: 10.1186/1472-6947-13-7. 4 and 5. Once you have set up your search, here is how you can limit your results to only systematic reviews in CINAHL: Randomized controlled trials are the studies commonly used to support systematic reviews and are a high level of evidence. Previous studies have investigated the added value of different databases on different topics [8,9,10,11,12,13,14,15]. To ensure adequate performance in searches (i.e., recall, precision, and number needed to read), we find that literature searches for a systematic review should, at minimum, be performed in the combination of the following four databases: Embase, MEDLINE (including Epub ahead of print), Web of Science Core Collection, and Google Scholar. We assessed the frequency at which databases and combinations would achieve varying levels of recall (i.e., 95%). 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. 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. 9v[-[TkBaly.Ja%"uu'Nd&nNSevS}VXcS63#qN This Spanish language database contains full text for 130 peer-reviewed medical journals in native Spanish. who wins student body president riverdale.

Ahntastic Adventures in Silicon Valley The Cochrane Handbook recommends searching MEDLINE, Cochrane CENTRAL, and Embase for systematic reviews of RCTs. Because of this major limitation, the question of which databases are necessary to retrieve all relevant references for a systematic review remains unanswered. Furthermore, it is time-consuming for reviewers who have to screen more, and likely irrelevant, titles and abstracts. WB designed the searches used in this study and gathered the data.

There is an overlap in the journals indexed by these two databases. @mR]L#-wbtR5Q 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. 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. 2015 Jun 26;4:82. doi: 10.1186/s13643-015-0074-7.

The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). The purpose of this research was to determine which of three databases, CINAHL, EMBASE or MEDLINE, should be accessed when researching nursing topics. Although Embase covers MEDLINE, it apparently does not index every article from MEDLINE. The other authors declare no competing interests. Literature search parameters marginally improved the pooled estimate accuracy for ultrasound in detecting deep venous thrombosis.

Figure1 shows the percentages of reviews where a certain database combination led to a certain recall. Of the 11 references included in this review, one was found only in Google Scholar and one only in Web of Science. California Privacy Statement, If the research question is more interdisciplinary, a broader science database such as Web of Science is likely to add value. Comparing International Pharmaceutical Abstracts and MEDLINE. A pragmatic evaluation of a new method for librarian-mediated literature searches for systematic reviews. The four databases that had retrieved the most unique references (Embase, MEDLINE, Web of Science, and Google Scholar) were investigated individually and in all possible combinations (see Table4). 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.

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. This search is then optimized. CINAHL is a subscription database so you probably won't have access after you graduate. Bramer, W.M., Rethlefsen, M.L., Kleijnen, J. et al.
