Transcript. j 'o WB has received travel allowance from Embase for giving a presentation at a conference. 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. 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. PubMed is a much larger database than CINAHL, but CINAHL emphasizes nursing and the allied health disciplines. A fast and easy research tool for nursing and allied health professionals with access to content coverage including over 50 nursing specialties, speech and language pathology, nutrition, general health and medicine and more. 2005;93:7480. Once optimal recall is achieved, macros are used to translate the search syntaxes between databases, though manual adaptation of the thesaurus terms is still necessary.

Higgins JPT, Green S. Cochrane handbook for systematic reviews of interventions: The Cochrane Collaboration, London, United Kingdom. We have not yet gathered enough data to be able to make a full comparison between Embase and Scopus. The sum of all these values is the total probability of acceptable recall in the random sample. PubMed Central (PMC) is a free full-text archive of biomedical and life sciences journal literature at the U.S. National Institutes of Health's National Library of Medicine (NIH/NLM). Wichor M. Bramer. 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. In 73 of these, the searches and results had been documented by the first author of this article at the time of the last search. 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. disadvantages of cinahl database. Size mOkV1#8 (uTb For the individual databases and combinations that were used in those reviews, we multiplied the frequency of occurrence in that set of 200 with the probability that the database or combination would lead to an acceptable recall (which we defined at 95%) that we had measured in our own data. l1FcqL@Bk>>T It offers job search and workplace skills improvement, skill building in reading, writing, math, and basic science, career certification and licensure exam prep, college and grad school entrance test prep, GED test prep, and more. 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. See Table1 for definitions of these measures. Google Scholar, Zheng MH, Zhang X, Ye Q, Chen YP. iOm3w]9`V>@X(xF$u,mA5US{^2w" `15p3SCzSM2w+!

Systematic Reviews [10] and van Enst et al. Search Limits. 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. In both these reviews, the topic was highly related to the topic of the database. Beyer FR, Wright K. Can we prioritise which databases to search? In Excel, we calculated the performance of each individual database and various combinations. Are MEDLINE searches sufficient for systematic reviews and meta-analyses of the diagnostic accuracy of depression screening tools? To learn more about Boolean operators, please see this Quick Answer: Here is an example of how to put together a complex search in CINAHL: Note: If you have not already logged in to the Library databases, you will be prompted to log in with your myWalden Portal user name and password. Complexity The provision of the functionality we expect of a good DBMS makes the DBMS an extremely complex piece of software. Cite this article.

Percentage of systematic reviewsof a certain domainfor which the combination Embase, MEDLINE and Cochrane CENTRAL reached a certain recall. Syst Rev. 1990;23:58393. Previous studies have investigated the added value of different databases on different topics [8,9,10,11,12,13,14,15]. The collection contains thousands of proprietary, copyrighted images depicting normal anatomy, physiology, embryology, and histology, as well as the web's largest repository of reference illustrations depicting surgery, trauma, pathology, diseases and conditions. <>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/Annots[ 9 0 R 10 0 R] /MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> J Med Libr Assoc. 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.

These values were calculated both for all reviews combined and per individual review. PubMed Can Fam Physician. Article For four out of five systematic reviews that limited to randomized controlled trials (RCTs) only, the traditional combination retrieved 100% of all included references. Correspondence to The datasets generated and/or analyzed during the current study are available from the corresponding author on a reasonable request. Figure4 shows the distribution of this value for individual reviews. Sixteen percent of the included references (291 articles) were only found in a single database; Embase produced the most unique references (n=132). kON0=ArP35x`*[r(DYVBa9BJ2w\LueOJ=i.dR;mmP/P stream sharing sensitive information, make sure youre on a federal Librarian co-authors correlated with higher quality reported search strategies in general internal medicine systematic reviews. We aimed to determine the optimal combination of databases needed to conduct efficient searches in systematic reviews and whether the current practice in published reviews is appropriate. Systematic reviews of epidemiology in diabetes: finding the evidence. The database itself is unfiltered, but includes many filtered items like systematic reviews. 2005;58:86773. In general, we use the first 200 references as sorted in the relevance ranking of Google Scholar. Using the results in this research, review teams can decide, based on their idea of acceptable recall and the desired probability which databases to include in their searches. Of all reviews in which we searched CINAHL and PsycINFO, respectively, for 6 and 9% of the reviews, unique references were found. One hundred and fifty-nine journals are uniquely indexed in BNI compared with the basic version of CINAHL. 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 aim of our research is to determine the combination of databases needed for systematic review searches to provide efficient results (i.e., to minimize the burden for the investigators without reducing the validity of the research by missing relevant references). The site is secure. Most of the previous studies did not include these two databases in their research. However, searching databases is laborious and time-consuming, as syntax of search strategies are database specific. Our conclusion that Web of Science and Google Scholar are needed for completeness has not been shared by previous research. Bookshelf When the overall number of hits was low, we additionally searched Scopus, and when appropriate for the topic, we included CINAHL (EBSCOhost), PsycINFO (Ovid), and SportDiscus (EBSCOhost) in our search. 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. To categorize the types of patient/population and intervention, we identified broad MeSH terms relating to the most important disease and intervention discussed in the article. This database provides nearly 550 scholarly full text journals focusing on many medical disciplines. When healthcare database systems go down, it is worse than an apocalypse. Quick Answer: What are Boolean operators? Figure1 shows the percentages of reviews where a certain database combination led to a certain recall. Health Inf Libr J. endobj This filter can be usedfind articles that are clinically-sound. In 72% of studied systematic reviews, the combination of Embase, MEDLINE, Web of Science, and Google Scholar retrieved all included references. BMC Med Res Methodol. The recall of the database combinations was calculated over all included references retrieved by any database. Res Synth Methods. 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. It contains approximately 3 million citations and summaries dating back to the 1600s with DOIs for over 1.4 million records. The references to these reviews can be found in Additional file 1. Using both Web of Science and Google Scholar in addition to MEDLINE and Embase increased the overall recall to 98.3%. 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.
