2005;93:7480. The sum of all these values is the total probability of acceptable recall in the random sample. This site needs JavaScript to work properly. Note: With this limiter you will need to evaluate your results to determine what type of evidence each article contains. Bramer WM, Giustini D, Kramer BMR. Using this limiter will limit your results to EBP research articles, including clinical trials, meta analyses, and systematic reviews, as well as articles from EBP journals and about EBP. Once you have set up your search, here is how you can limit your results to only case studies: CINAHL Plus with Full Text offers a number of filters or limiters that can help you find only specific types of studies. 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. Most articles on this topic draw their conclusions based on the coverage of databases [14]. In this case, the number of hits from Google Scholar was limited to 100. Depending on the goal of the search, different measures may be optimized. A comparative study of clinical end-user and librarian searches. 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. Table3 displays the number of unique results retrieved for each single database. Stevinson C, Lawlor DA. Exploring the 'Patient Experience' of Individuals with Limited English Proficiency: A Scoping Review. The database includes all charts, diagrams, graphs, tables, photos, and other graphical elements essential to medical research. 2008;39:e139. In addition, Michaleff et al. "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. 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]. 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. <>>> Article In general, the expert organization and content of library databases will save you time and yield you the most relevant, appropriate, and authoritative results. Manage cookies/Do not sell my data we use in the preference centre. 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. 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. 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. An overview of the broad topical categories covered in these reviews is given in Table2. Imagine you are a patient with cancer and your doctor can't order your pain medication. Because of this major limitation, the question of which databases are necessary to retrieve all relevant references for a systematic review remains unanswered. % 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. 2005 Jan;58(1):20-5. doi: 10.1016/j.jclinepi.2004.06.001. 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%. The X-axis represents the percentage of reviews for which a specific combination of databases, as shown on the y-axis, reached a certain recall (represented with bar colors). Posted on 16 December 2021 - 7:39 pm by . We are aware that the Cochrane Handbook [7] recommends more than only these databases, but further recommendations focus on regional and specialized databases. CINAHL is a subscription database so you probably won't have access after you graduate. "N` ;:"Z,Ov;s90yz` x:Na|8{4Bl9fxbRZk96L.00t4+a6.dx8Uc*$Ea=KhIn+4Byp0>*Wu$(3}sd6[J6\Lx%U Literature search parameters marginally improved the pooled estimate accuracy for ultrasound in detecting deep venous thrombosis. See Fig. Recommended articles lists articles that we recommend and is powered by our AI driven recommendation engine. 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%. MEDLINE did find unique references that had not been found in Embase, although our searches in Embase included all MEDLINE records. Abbreviations: EM Embase, ML MEDLINE, WoS Web of Science, GS Google Scholar. CINAHL provided the majority of relevant articles for the second search, on computers and privacy, but inclusion of MEDLINE and EMBASE enhanced retrieval somewhat. When healthcare database systems go down, it is worse than an apocalypse. We documented the department of the first author. Cochrane CENTRAL is absent from the table, as for the five reviews limited to randomized trials, it did not add any unique included references. For a sample of 200 recently published systematic reviews, we calculated how many had used enough databases to ensure 95% recall. Bramer WM, Giustini D, Kramer BM, Anderson PF. Since the introduction of the more complete MEDLINE collection Epub Ahead of Print, In-Process & Other Non-Indexed Citations, and Ovid MEDLINE, the need to separately search PubMed as supplied by publisher has disappeared. Our conclusion that Web of Science and Google Scholar are needed for completeness has not been shared by previous research. Our study shows that, to reach maximum recall, searches in systematic reviews ought to include a combination of databases. ``6C~8 '* "r#=e ax A+ 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. McKibbon KA, Haynes RB, Dilks CJW, Ramsden MF, Ryan NC, Baker L, Flemming T, Fitzgerald D. How good are clinical MEDLINE searches? Bramer, W.M., Rethlefsen, M.L., Kleijnen, J. et al.

Syst Rev. 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. 3099067 In both these reviews, the topic was highly related to the topic of the database. 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. 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. 3 0 obj Optimal database combinations for literature searches in systematic reviews: a prospective exploratory study. Article Lemeshow AR, Blum RE, Berlin JA, Stoto MA, Colditz GA. Searching one or two databases was insufficient for meta-analysis of observational studies. PMC Lorenzetti DL, Topfer L-A, Dennett L, Clement F. Value of databases other than MEDLINE for rapid health technology assessments. 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. Searching only Embase produced an NNR of 57 on average, whereas, for the optimal combination of four databases, the NNR was 73. Halladay et al. The .gov means its official. Films Media Group serves the education community through its four brands: Films for the Humanities and Sciences, Cambridge Educational, Meridian Education, and Shopware. MEDLINE is a great resource for medical . 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. See Fig. Improving search efficiency for systematic reviews of diagnostic test accuracy: an exploratory study to assess the viability of limiting to MEDLINE, EMBASE and reference checking. 1990;23:58393. Using data sources beyond PubMed has a modest impact on the results of systematic reviews of therapeutic interventions. Embase retrieved the most unique included references, followed by MEDLINE, Web of Science, and Google Scholar. That is with the generous assumption that the searches in those databases had been designed sensitively enough. 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. PubMed does not. <>/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>> 2004;12:22832. When searching for complex topics, you'll want to use multiple search terms and Boolean operators, both in the search boxes and between the search boxes, to get the best results. CAS The researchers that requested the search received a deduplicated EndNote file from which they selected the references relevant for inclusion in their systematic review. New candidate terms are added to the basic search and evaluated. We selected the domain from a pre-defined set of broad domains, including therapy, etiology, epidemiology, diagnosis, management, and prognosis. 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. Federal government websites often end in .gov or .mil. This filter can be usedfind articles that are clinically-sound. official website and that any information you provide is encrypted Systematic review searchers should consider using these databases if they are available to them, and if their institution lacks availability, they should ask other institutes to cooperate on their systematic review searches. Select an option by finding it in the list and clicking on it (it will then be highlighted). For four out of five systematic reviews that limited to randomized controlled trials (RCTs) only, the traditional combination retrieved 100% of all included references. PubMed Central 2 0 obj J Clin Epidemiol. Based on the record numbers of the search results in EndNote, we determined from which database these references came. The purpose of this research was to determine which of three databases, CINAHL, EMBASE or MEDLINE, should be accessed when researching nursing topics. Of the five reviews that included only RCTs, four reached 100% recall if MEDLINE, Web of Science, and Google Scholar combined were complemented with Cochrane CENTRAL. 5 Howick Place | London | SW1P 1WG. Figure1 shows the percentages of reviews where a certain database combination led to a certain recall. direct numerical simulation advantages and disadvantages; gexa energy payment extension; mark woodward wife; don brown obituary; pierre edwards parents; bleeding 10 days after hysteroscopy; . Int J Technol Assess Health Care. Bookshelf 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. See Table1 for definitions of these measures. We identified all included references that were uniquely identified by a single database. 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. These could be retrieved by searching PubMed with the subset as supplied by publisher. 8600 Rockville Pike Privacy Providing searchable cited references for nearly 1,000 journals, is another added benefit.

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. Within systematic reviews, when searching for relevant references, it is advisable to use multiple databases. ?lq!9!OW$2w1tp=/0 0aPz6Kx|M}97_jn{oy0@o65I>KrjPov= D@H?z`. 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. Hold down the Ctrl key to select multiple options. PubMedGoogle Scholar. 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. . ProQuest Nursing & Allied Health Source provides abstracting and indexing for more than 1,050 titles, with over 875 titles in full-text, plus more than 12,300 full text dissertations representing the most rigorous scholarship in nursing and related fields. 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%. We estimate that 60% of published systematic reviews do not retrieve 95% of all available relevant references as many fail to search important databases. &Jl1/>nw\CCX=prz Dcr8UBW3L`Du8*r (+P/:SXQB^ Whether Embase and Web of Science can be replaced by Scopus remains uncertain.
