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. We selected the domain from a pre-defined set of broad domains, including therapy, etiology, epidemiology, diagnosis, management, and prognosis. Embase retrieved the most unique included references, followed by MEDLINE, Web of Science, and Google Scholar. 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. 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. Comparison of CINAHL, EMBASE, and MEDLIN . Medicine, Dentistry, Nursing & Allied Health. This search is then optimized.

WB, JK, and OF designed the study. MeSH 2014;67:11929. Unable to load your collection due to an error, Unable to load your delegates due to an error. Over a third of the reviews were therapeutic, while slightly under a quarter answered an etiological question. Ws"30z@+RY{"+NTzXnnf.ote{X-C.!0rxY_K+LSA12"fDAKJtk/FQS. 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. Systematic Reviews Beckles Z, Glover S, Ashe J, Stockton S, Boynton J, Lai R, Alderson P. Searching CINAHL did not add value to clinical questions posed in NICE guidelines. Beyer FR, Wright K. Can we prioritise which databases to search? A comparison of the performance of seven key bibliographic databases in identifying all relevant systematic reviews of interventions for hypertension. https://doi.org/10.1186/s13643-017-0644-y, DOI: https://doi.org/10.1186/s13643-017-0644-y. Recommended articles lists articles that we recommend and is powered by our AI driven recommendation engine. We determined the databases that contributed most to the reviews by the number of unique references retrieved by each database used in the reviews. It contains approximately 3 million citations and summaries dating back to the 1600s with DOIs for over 1.4 million records. J Clin Epidemiol. Before This search was used in earlier research [21]. Our conclusion that Web of Science and Google Scholar are needed for completeness has not been shared by previous research. While previous studies determined the coverage of databases, we analyzed the actual retrieval from the original searches for systematic reviews. The topics of the reviews studied here may simply have fallen into those categories, though the diversity of the included reviews may point to a more universal applicability. Most articles on this topic draw their conclusions based on the coverage of databases [14]. By closing this message, you are consenting to our use of cookies. For all but one domain, the traditional combination of Embase, MEDLINE, and Cochrane CENTRAL did not retrieve enough included references. author reply e140.

Nursing & Allied Health SourceTM provides users with reliable healthcare information covering nursing, allied health, alternative and complementary medicine. 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. Halladay CW, Trikalinos TA, Schmid IT, Schmid CH, Dahabreh IJ. The complete results from all databases used for each of the systematic reviews were imported into a unique EndNote library upon search completion and saved without deduplication for this research. If an included reference was not found in the EndNote file, we presumed the authors used an alternative method of identifying the reference (e.g., examining cited references, contacting prominent authors, or searching gray literature), and we did not include it in our analysis. The highest scoring database combination without Embase is a combination of MEDLINE, Web of Science, and Google Scholar, but that reaches satisfactory recall for only 39% of all investigated systematic reviews, while still requiring a paid subscription to Web of Science. Although Embase covers MEDLINE, it apparently does not index every article from MEDLINE. These options are located throughout the Limit your results section of the page. 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. 2005 Jan 8;5:2. doi: 10.1186/1471-2288-5-2. 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. Previous studies have investigated the added value of different databases on different topics [8,9,10,11,12,13,14,15]. Google Scholar. Finding resources: MEDLINE. Ahntastic Adventures in Silicon Valley volume6, Articlenumber:245 (2017) Bramer WM, Rethlefsen ML, Mast F, Kleijnen J. %PDF-1.5 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%. Thedatabase itself is unfiltered, but includes many filtered items like systematic reviews. MEDLINE did find unique references that had not been found in Embase, although our searches in Embase included all MEDLINE records. and transmitted securely. This limiter box allows you to select specific article types. 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]. A pragmatic evaluation of a new method for librarian-mediated literature searches for systematic reviews. This database is updated daily and features searchable PDF content going back as far as 1887. Of the individual databases, Embase had the highest overall recall (85.9%). Moreover, in combinations where the number of results was greatly reduced, the recall of included references was lower. EMBASE versus MEDLINE for family medicine searches: can MEDLINE searches find the forest or a tree? Did you know that with a free Taylor & Francis Online account you can gain access to the following benefits? Some reviewers might accept a potential loss of 5% of relevant references; others would want to pursue 100% recall, no matter what cost. The reviews covered a wide variety of disease, none of which was present in more than 12% of the reviews. In addition to journal articles, CINAHL includes books, book chapters, dissertations, and computer programs. These could be retrieved by searching PubMed with the subset as supplied by publisher. The purpose of this research was to determine which of three databases, CINAHL, EMBASE or MEDLINE, should be accessed when researching nursing topics. This research goes beyond retrospectively assessed coverage to investigate real search performance in databases. The purpose of this research was to determine which of three databases, CINAHL, EMBASE or MEDLINE, should be accessed when researching nursing topics. Stevinson C, Lawlor DA. When searching for a systematic review, recall is the most important aspect, as the researcher does not want to miss any relevant references. Phys Ther. Films Media Group is the leading source of high-quality video and multimedia for academic, vocational and life-skills content. Nearly 5,000 journals are read and their individual articles indexed and added to the MEDLINE database, which contains information about over 12 million journal articles. 2013;30:4958. It is laborious for searchers to translate a search strategy into multiple interfaces and search syntaxes, as field codes and proximity operators differ between interfaces. Until 2016, the most complete MEDLINE selection in Ovid still lacked the electronic publications that were already available in PubMed. We calculated the ratio between the number of results found when searching all databases, including databases not included in our analyses, such as Scopus, PsycINFO, and CINAHL, and the number of results found searching a selection of databases. >/- 8CqD 0:J AT~Xr Bx:.}U_y>gEdUug1tXA ed! 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.
