While previous studies determined the coverage of databases, we analyzed the actual retrieval from the original searches for systematic reviews. Although Embase covers MEDLINE, it apparently does not index every article from MEDLINE. Using data sources beyond PubMed has a modest impact on the results of systematic reviews of therapeutic interventions. Together, these reviews included a total of 1830 references. Investigators and information specialists searching for relevant references for a systematic review (SR) are generally advised to search multiple databases and to use additional methods to be able to adequately identify all literature related to the topic of interest [1,2,3,4,5,6]. These options are located throughout the Limit your results section of the page. A recent paper tried to find an acceptable number needed to read for adding an additional database; sadly, however, no true conclusion could be drawn [20]. 2013;2:115. PubMed Lawrence DW. The site is secure. 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. Google Scholar. author reply e140. 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. Part of 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. Are included references being missed because the review authors failed to search a certain database? Phys Ther. 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). <>/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>> PMC 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.

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. 1990;23:58393. That is with the generous assumption that the searches in those databases had been designed sensitively enough. These are mostly unique PubMed references, which are not assigned MeSH terms, and are often freely available via PubMed Central. 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. Literature search parameters marginally improved the pooled estimate accuracy for ultrasound in detecting deep venous thrombosis. 2006 Jul;59(7):710-4. doi: 10.1016/j.jclinepi.2005.09.013. In 12 reviews (52%), Scopus retrieved 100% of all included references retrieved by Embase or Web of Science. [17] found the added value of other databases only for newer, non-indexed references.

In the other 48%, the recall by Scopus was suboptimal, in one occasion as low as 38%. How do I view content? Of the individual databases, Embase had the highest overall recall (85.9%). People also read lists articles that other readers of this article have read. PubMed A total of 292 (17%) references were found by only one database. Reviews included in the research. For 55 reviews, we determined the domain. 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. In Excel, we calculated the performance of each individual database and various combinations. Google Scholar. Films Media Group serves the education community through its four brands: Films for the Humanities and Sciences, Cambridge Educational, Meridian Education, and Shopware. 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. Where should the pharmacy researcher look first? -$P*C! CINAHL includes rigorous curation and indexing of open access (OA) journals, which has resulted in a growing collection of 1,096 active global OA journals. using CINAHL alone.

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. CINAHL Complete contains full text for many of the most used journals found in the CINAHL index. Figure4 shows the distribution of this value for individual reviews. 2016;16:161. van Enst WA, Scholten RJ, Whiting P, Zwinderman AH, Hooft L. Meta-epidemiologic analysis indicates that MEDLINE searches are sufficient for diagnostic test accuracy systematic reviews. Moreover, in combinations where the number of results was greatly reduced, the recall of included references was lower. What is considered acceptable recall for systematic review searches is open for debate and can differ between individuals and groups. Transcript. In short, the method consists of an efficient way to combine thesaurus terms and title/abstract terms into a single line search strategy. The three databases were searched for citations on topics selected by three nurse researchers and the results were compared. 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. In addition to journal articles, CINAHL includes books, book chapters, dissertations, and computer programs. Though we suspect that searchers who are not information specialists or librarians would have a higher possibility of less well-constructed searches and searches with lower recall, even highly trained searchers differ in their approaches to searching. 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. In that case, Google Scholar might add value by searching the full text of articles. Select an option by finding it in the list and clicking on it (it will then be highlighted). 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 %. Of all reviews in which we searched CINAHL and PsycINFO, respectively, for 6 and 9% of the reviews, unique references were found. Unauthorized use of these marks is strictly prohibited. Bramer WM, de Jonge GB, Rethlefsen ML, Mast F, Kleijnen J.

To determine how searching multiple databases affected precision, we calculated for each combination the ratio between the original precision, observed when all databases were searched, and the precision calculated for different database combinations. WB drafted the first manuscript, which was revised critically by the other authors. Article These could be retrieved by searching PubMed with the subset as supplied by publisher. Nursing: Indexes & Databases. For each published systematic review, we extracted the references of the included studies. Note: Putting quotation marks around phrases tells the database to search for these words as a phrase and not as individual words. J Clin Epidemiol. 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. Because this is a novel finding, we cannot conclude whether it is due to our dataset or to a generalizable principle. Additionally, search strategies are limited to a maximum of 256 characters, which means that creating a thorough search strategy can be laborious. Health Inf Libr J. Most articles on this topic draw their conclusions based on the coverage of databases [14]. There is an overlap in the journals indexed by these two databases. Eighty-one journals are uniquely indexed in BNI compared with all versions of CINAHL. Conclusion Select English Language texts unless you are capable of reading articles in foreign languages. Based on the record numbers of the search results in EndNote, we determined from which database these references came. Almost all reviews (97%) reported a search in MEDLINE. Optimal database combinations for literature searches in systematic reviews: a prospective exploratory study. Using similar calculations, also shown in Table5, we estimated the probability that 100% of relevant references were retrieved is 23%. 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. Ross-White A, Godfrey C. Is there an optimum number needed to retrieve to justify inclusion of a database in a systematic review search? The purpose of this research was to determine which of three databases, CINAHL, EMBASE or MEDLINE, should be accessed when researching nursing topics.

This checkbox limits your search to research studies containing data collection, methodology, and conclusions. Of the 11 references included in this review, one was found only in Google Scholar and one only in Web of Science. Is the coverage of Google Scholar enough to be used alone for systematic reviews. Before This filter can be usedfind articles that are clinically-sound. "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. 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. A nursing qualitative systematic review required MEDLINE and CINAHL for study identification. The three databases were searched for citations on topics selected by three nurse researchers and the results were compared. For all individual databases or combinations of the four important databases from our research (MEDLINE, Embase, Web of Science, and Google Scholar), we multiplied the frequency of occurrence of that combination in the random set, with the probability we found in our research that this combination would lead to an acceptable recall of 95%. 2019 Aug;21(4):853-878. doi: 10.1007/s10903-018-0816-4.

Bramer WM, Rethlefsen ML, Mast F, Kleijnen J. @mR]L#-wbtR5Q One explanation for our finding may be that if the research question is very specific, the topic of research might not always be mentioned in the title and/or abstract. ; ; For the databases that retrieved the most unique included references, we calculated the number of references retrieved (after deduplication) and the number of included references that had been retrieved by all possible combinations of these databases, in total and per review. 2013 Jan 9;13:7. doi: 10.1186/1472-6947-13-7. An official website of the United States government. Within systematic reviews, when searching for relevant references, it is advisable to use multiple databases. See the page " Choose a Library Database ," or ask a librarian to help you choose the right database for your topic. Syst Rev 6, 245 (2017). The calculation is shown in Table5. Previous studies have investigated the added value of different databases on different topics [8,9,10,11,12,13,14,15]. We analyzed whether the added value of Web of Science and Google Scholar was dependent of the domain of the review. The Cochrane Handbook, for example, recommends the use of at least MEDLINE and Cochrane Central and, when available, Embase for identifying reports of randomized controlled trials [7]. In 72% of studied systematic reviews, the combination of Embase, MEDLINE, Web of Science, and Google Scholar retrieved all included references. When looking at the overall recall, the combination of Embase and MEDLINE and either Google Scholar or Web of Science could be regarded sufficient with 96% recall. Films Media Group is the leading source of high-quality video and multimedia for academic, vocational and life-skills content. 1996 Jul;84(3):402-8.
