9v[-[TkBaly.Ja%"uu'Nd&nNSevS}VXcS63#qN In 12 reviews (52%), Scopus retrieved 100% of all included references retrieved by Embase or Web of Science. Even when taking into account that many searchers consider the use of Scopus as a replacement of Embase, plus taking into account the large overlap of Scopus and Web of Science, this estimate remains similar. For a sample of 200 recently published systematic reviews, we calculated how many had used enough databases to ensure 95% recall. MEDLINE did find unique references that had not been found in Embase, although our searches in Embase included all MEDLINE records. Cite this article. Stevinson C, Lawlor DA. This shows that many database searches missed relevant references. Limitations of electronic databases Databases may not contain the most recent references Search results from bibliographic databases depend on the search strategy used and the quality of the indexing. scott burns lincoln ventures. Technical Problems Every computer system will have a breakdown. BNI is represented three times in the table because the number of unique titles per database depends on whether CINAHL, CINAHL Plus or CINAHL Complete is being 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. A multi-disciplinary database, with more than 6,100 full-text periodicals, including more than 5,100 peer-reviewed journals. J Clin Epidemiol. j 'o This study also highlights once more that searching databases alone is, nevertheless, not enough to retrieve all relevant references. 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. For four out of five systematic reviews that limited to randomized controlled trials (RCTs) only, the traditional combination retrieved 100% of all included references. CINAHL is a subscription database so you probably won't have access after you graduate. 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. &Jl1/>nw\CCX=prz Dcr8UBW3L`Du8*r (+P/:SXQB^ Ross-White A, Godfrey C. Is there an optimum number needed to retrieve to justify inclusion of a database in a systematic review search? Performance of a search can be expressed in different ways. The Cochrane Handbook recommends searching MEDLINE, Cochrane CENTRAL, and Embase for systematic reviews of RCTs. J Clin Epidemiol. 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. Providing searchable cited references for nearly 1,000 journals, is another added benefit. 2014;21:34354. pros and cons of cinahl database Categories. Disadvantages of Databases 1. Thedatabase itself is unfiltered, but includes many filtered items like systematic reviews. Based on our calculations made by looking at random systematic reviews in PubMed, we estimate that 60% of these reviews are likely to have missed more than 5% of relevant references only because of the combinations of databases that were used. Of the 11 references included in this review, one was found only in Google Scholar and one only in Web of Science. We are aware that the Cochrane Handbook [7] recommends more than only these databases, but further recommendations focus on regional and specialized databases. Our experience in this study shows that additional efforts, such as hand searching, reference checking, and contacting key players, should be made to retrieve extra possible includes. California Privacy Statement, 2018. 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%. Because precision is defined as the number of relevant references divided by the number of total results, we see a strong correlation with the total number of results. 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. In our analyses, we combined the results from MEDLINE in Ovid and PubMed (the subset as supplied by publisher) into one database labeled MEDLINE. Searching multiple databases for systematic reviews: added value or diminishing returns? Of the individual databases, Embase had the highest overall recall (85.9%). The three databases were searched for citations on topics selected by three nurse researchers and the results were compared. "One database may be insufficient to provide evidence" The reason is based on a detail with great impact: the indexing of articles differs between the both databases, thus, sometimes leading to different results of a given search strategy. On 5 January 2017, we searched PubMed for articles with the phrase systematic review in the title. PubMed Central For the search of nursing care literature on a medical condition, it was helpful to search both CINAHL and MEDLINE. A systematic approach to searching: how to perform high quality literature searches more efficiently. Anyone you share the following link with will be able to read this content: Sorry, a shareable link is not currently available for this article. Article Here is an example of a search for a cohort study in CINAHL: A case study, or case report, is a research method involving a detailed investigation of a single individual or a single organized group. For example, in 48% of all systematic reviews, the combination of Embase and MEDLINE (with or without Cochrane CENTRAL; Cochrane CENTRAL did not add unique relevant references) reaches a recall of at least 95%. Note: Putting quotation marks around phrases tells the database to search for these words as a phrase and not as individual words. Can Fam Physician. Google Scholar. Some reviewers might accept a potential loss of 5% of relevant references; others would want to pursue 100% recall, no matter what cost. Article https://doi.org/10.1186/s13643-017-0644-y, DOI: https://doi.org/10.1186/s13643-017-0644-y. andy gibb last interview. Our conclusion that Web of Science and Google Scholar are needed for completeness has not been shared by previous research. There are disadvantages to using multiple databases. 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. For each published systematic review, we extracted the references of the included studies. 2013;30:4958. Google Scholar adds relevant articles not found in the other databases, possibly because it indexes the full text of all articles. We analyzed whether the added value of Web of Science and Google Scholar was dependent of the domain of the review. . Reviews included in the research. Bramer, W.M., Rethlefsen, M.L., Kleijnen, J. et al. Because this is a novel finding, we cannot conclude whether it is due to our dataset or to a generalizable principle. One hundred and fifty-nine journals are uniquely indexed in BNI compared with the basic version of CINAHL. iOm3w]9`V>@X(xF$u,mA5US{^2w" `15p3SCzSM2w+!

Therefore, we research the probability that single or various combinations of databases retrieve the most relevant references in a systematic review by studying actual retrieval in various databases. 2015 Jun 26;4:82. doi: 10.1186/s13643-015-0074-7. 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.

Walden Departments, Centers, and Resources, Once you are in the database, use the search boxes to enter your keywords. This can be offset, as noted above, by going to the EBSCOhost (Health) package of databases. Conclusion Design: A comprehensive literature review was undertaken through a thorough review of Medline and CINAHL databases using the keywords of "audit", "audit of audits", and "evaluation of audits" and a handsearch of . Clipboard, Search History, and several other advanced features are temporarily unavailable. Once validated and certified for inclusion, these OA journals are treated with high-quality subject indexing and sophisticated, precise/accurate full-text linking. 8600 Rockville Pike Of these, 84 references (4.6%) had not been retrieved by our database searches and were not included in our analysis, leaving in total 1746 references.

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. For example, around a third of the reviews (37%) relied on the combination of MEDLINE and Embase. Exploring the 'Patient Experience' of Individuals with Limited English Proficiency: A Scoping Review. Beginning in May 2013, the number of records retrieved from each search for each database was recorded at the moment of searching. 2016;16:113. 2011;91:1907. 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. 4 and 5. A comparison of the performance of seven key bibliographic databases in identifying all relevant systematic reviews of interventions for hypertension. 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].

According to our data, PubMeds as supplied by publisher subset retrieved 12 unique included references, and it was the most important addition in terms of relevant references to the four major databases. We found that two databases previously not recommended as essential for systematic review searching, Web of Science and Google Scholar, were key to improving recall in the reviews we investigated. At Erasmus MC, search strategies for systematic reviews are often designed via a librarian-mediated search service. Syst Rev. An overview of the broad topical categories covered in these reviews is given in Table2. However, Embase is only accessible via a paid subscription, which generally makes it challenging for review teams not affiliated with academic medical centers to access. CAS using CINAHL alone. 2008;39:e139. Are included references being missed because the review authors failed to search a certain database? endobj Cochrane CENTRAL is absent from the table, as for the five reviews limited to randomized trials, it did not add any unique included references. Part of Rathbone J, Carter M, Hoffmann T, Glasziou P. Syst Rev. The purpose of this research was to determine which of three databases, CINAHL, EMBASE or MEDLINE, should be accessed when researching nursing topics. These results may not be generalizable to other studies for other reasons. Res Synth Methods. Phys Ther. 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. 2 - CRzB:x{m9*eZvs@~&AWSiwY5a%Ofn(ehsVvu-O#Y+(t &c-SvTtFg *@WsWTy._,i@R(ay>EK4J=z}8S6(Cw viV%Q%bs-&{ Before Subirana M, Sol I, Garcia JM, Gich I, Urrtia G.

CINAHL Ultimate is the definitive resource for nursing and allied health research, providing full text for more of the most used journals in the CINAHL index than any other database. Fifty one of the 81 titles . [26] found that Cochrane CENTRAL included 95% of all RCTs included in the reviews investigated. Figure1 shows the percentages of reviews where a certain database combination led to a certain recall. Is the coverage of Google Scholar enough to be used alone for systematic reviews. However, whether an article is present in a database may not translate to being found by a search in that database. We selected the domain from a pre-defined set of broad domains, including therapy, etiology, epidemiology, diagnosis, management, and prognosis. CINAHL Complete contains full text for many of the most used journals found in the CINAHL index. Using data sources beyond PubMed has a modest impact on the results of systematic reviews of therapeutic interventions. HR;QBYVCU-7;-7O?zIo =IBK OH)k11H?3xQao7~Z| In the other 48%, the recall by Scopus was suboptimal, in one occasion as low as 38%. Designed for an audience ranging from novice test consumers to experienced professionals, the MMY series contains information essential for a complete evaluation of test products within such diverse areas as psychology, education, business, and leadership. Though we occasionally used the regional databases LILACS and SciELO in our reviews, they did not provide unique references in our study. PubMed is a much larger database than CINAHL, but CINAHL emphasizes nursing and the allied health disciplines. Additionally, search strategies are limited to a maximum of 256 characters, which means that creating a thorough search strategy can be laborious. However, for one review of this domain, the recall was 82%. Sixteen percent of the included references (291 articles) were only found in a single database; Embase produced the most unique references (n=132). We documented the department of the first author. 2016;5:39.

Systematic Reviews For each review that we investigated, we determined what the recall was for all possible different database combinations of the most important databases. Although Embase covers MEDLINE, it apparently does not index every article from MEDLINE. We use cookies to improve your website experience. This research goes beyond retrospectively assessed coverage to investigate real search performance in databases.

However, the combination with Google Scholar had a higher precision and higher median recall, a higher minimum recall, and a higher proportion of reviews that retrieved all included references. The contribution of databases to the results of systematic reviews: a cross-sectional study. A review of meta-analyses. It covers more than 50 nursing specialties and includes quick lessons, evidence-based care sheets, CEU modules and research instruments.
