Future research should continue to investigate recall of actual searches beyond coverage of databases and should consider focusing on the most optimal database combinations, not on single databases. The recall of the database combinations was calculated over all included references retrieved by any database. An overview of the broad topical categories covered in these reviews is given in Table2. This site needs JavaScript to work properly. Some reviewers might accept a potential loss of 5% of relevant references; others would want to pursue 100% recall, no matter what cost. All searches in this study were developed and executed by W.M.B. 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. On this page you will learn how to limit your results in CINAHL to: Video: CINAHL Quick Guide at Walden Library (YouTube), (2 min 24 sec) Recorded April 2020 official website and that any information you provide is encrypted 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. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). 11 reviews, where we were able to recheck all the databases used by the original review authors, had included a study that was uniquely identified from the CINAHL database. Whether Embase and Web of Science can be replaced by Scopus remains uncertain. Rethlefsen ML, Farrell AM, Osterhaus Trzasko LC, Brigham TJ. Syst Rev. We recommend that, regardless of their topic, searches for biomedical systematic reviews should combine Embase, MEDLINE (including electronic publications ahead of print), Web of Science (Core Collection), and Google Scholar (the 200 first relevant references) at minimum. We are aware that the Cochrane Handbook [7] recommends more than only these databases, but further recommendations focus on regional and specialized databases.

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. Lorenzetti DL, Topfer L-A, Dennett L, Clement F. Value of databases other than MEDLINE for rapid health technology assessments. %PDF-1.5 Ease in terms of accessibility is another advantage of ERIC and other data bases in that they can be accessed by computer or using print indexes published monthly. Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. 2013;66:10517. 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. EMBASE versus MEDLINE for family medicine searches: can MEDLINE searches find the forest or a tree? For a search related to nursing, .

Using data sources beyond PubMed has a modest impact on the results of systematic reviews of therapeutic interventions. % 2018. Syst Rev. 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. and transmitted securely. McKibbon KA, Haynes RB, Dilks CJW, Ramsden MF, Ryan NC, Baker L, Flemming T, Fitzgerald D. How good are clinical MEDLINE searches? For each published systematic review, we extracted the references of the included studies. how to send secure email attachments in gmail. 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. Conclusion 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. BMC Med Res Methodol. 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. 2016 Feb 9;5:27. doi: 10.1186/s13643-016-0197-5. New candidate terms are added to the basic search and evaluated. 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. For reviews in our study that included RCTs only, indeed, this recommendation was sufficient for four (80%) of the reviews. The combination of Embase, MEDLINE, Web of Science Core Collection, and Google Scholar performed best, achieving an overall recall of 98.3 and 100% recall in 72% of systematic reviews. In Excel, we calculated the performance of each individual database and various combinations. Unauthorized use of these marks is strictly prohibited. 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. 2016;87:713. 2008;39:e139. The databases avail-able include the Cochrane Collaboration, Medline (in various forms such as PubMed), Best Evidence10and Embase.The most widely used and most often recom-mended database isMedline. The search on substance abuse in pregnancy, not restricted to nursing literature, retrieved better results when searching both MEDLINE and EMBASE. <> For the search of nursing care literature on a medical condition, it was helpful to search both CINAHL and MEDLINE. From: Complementary Therapies for Physical Therapy, 2008 View all Topics Add to Mendeley Our earlier research had resulted in 206 systematic reviews published between 2014 and July 2016, in which the first author was affiliated with Erasmus MC [21]. PubMed does not. The three databases were searched for citations on topics selected by three nurse researchers and the results were compared. J Clin Epidemiol. On 5 January 2017, we searched PubMed for articles with the phrase systematic review in the title. Bramer WM, Rethlefsen ML, Mast F, Kleijnen J. The calculation is shown in Table5. 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. From the published journal article, we extracted the list of final included references. 2 0 obj Click in the check box below Evidence-Based Practice to select this option. Many articles written on this topic have calculated overall recall of several reviews, instead of the effects on all individual reviews. ?lq!9!OW$2w1tp=/0 0aPz6Kx|M}97_jn{oy0@o65I>KrjPov= D@H?z`. Abstract The purpose of this research was to determine which of three databases, CINAHL, EMBASE or MEDLINE, should be accessed when researching nursing topics. @mR]L#-wbtR5Q 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.

The datasets generated and/or analyzed during the current study are available from the corresponding author on a reasonable request. 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. We documented the department of the first author. Handwashing OR "Hand Washing" OR "Hand Rubs" OR "Hand Disinfection". The Cochrane Handbook recommends searching MEDLINE, Cochrane CENTRAL, and Embase for systematic reviews of RCTs. 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. Sixteen percent of the included references (291 articles) were only found in a single database; Embase produced the most unique references (n=132). >/- 8CqD 0:J AT~Xr Bx:.}U_y>gEdUug1tXA ed! This research goes beyond retrospectively assessed coverage to investigate real search performance in databases. 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. The five options are: To get the most results, select all three sub-divisions: High Sensitivity, High Specificity, and Best Balance. }UCby^4(-\SHU1B CPn(ULF{fUUog].[>~si|F] mykK+NGz "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 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. The three databases were searched for citations on topics selected by three nurse researchers and the results were compared. 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. Until 2016, the most complete MEDLINE selection in Ovid still lacked the electronic publications that were already available in PubMed. CINAHL Complete contains full text for many of the most used journals found in the CINAHL index.
