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. 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. Searching additional databases except PubMed are necessary for a systematic review. Bookshelf Subject-specific databases like PsycINFO only added unique references to a small percentage of systematic reviews when they had been used for the search. 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. For a sample of 200 recently published systematic reviews, we calculated how many had used enough databases to ensure 95% recall. [17] found the added value of other databases only for newer, non-indexed references. For reviews where RCTs are the desired study design, Cochrane CENTRAL may be similarly useful. In 12 reviews (52%), Scopus retrieved 100% of all included references retrieved by Embase or Web of Science. 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]. MEDLINEprovides authoritative medical information on medicine, nursing, dentistry, veterinary medicine, the health care system, pre-clinical sciences, and much more. 3 for the legend of the plots in Figs. 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. 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.

A comparison of the performance of seven key bibliographic databases in identifying all relevant systematic reviews of interventions for hypertension. A multi-disciplinary database, with more than 6,100 full-text periodicals, including more than 5,100 peer-reviewed journals. Until 2016, the most complete MEDLINE selection in Ovid still lacked the electronic publications that were already available in PubMed. 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. 5 Howick Place | London | SW1P 1WG. 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.

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. 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. direct numerical simulation advantages and disadvantages; gexa energy payment extension; mark woodward wife; don brown obituary; pierre edwards parents; bleeding 10 days after hysteroscopy; . and transmitted securely. Halladay et al. 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. That is with the generous assumption that the searches in those databases had been designed sensitively enough. <> Asterisk indicates that the recall of all databases has been calculated over all included references. 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. From the published journal article, we extracted the list of final included references. In addition, Michaleff et al. These results may not be generalizable to other studies for other reasons. Librarian co-authors correlated with higher quality reported search strategies in general internal medicine systematic reviews. Wilkins T, Gillies RA, Davies K. EMBASE versus MEDLINE for family medicine searches: can MEDLINE searches find the forest or a tree? J Clin Epidemiol. If this resulted in extraneous results, the search was subsequently limited using a distinct part of the title or a second author name. 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 . 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. Database designers and developers, the data and database administrators and end-users must understand this functionality to take full advantage of it.

Created by the National Library of Medicine,MEDLINEuses MeSH (Medical Subject Headings) indexing with tree, tree hierarchy, subheadings and explosion capabilities to search citations from over 4,800 current biomedical journals. 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. 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. Nursing: Indexes & Databases. 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. 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. 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 Excel, we calculated the performance of each individual database and various combinations. Using the results in this research, review teams can decide, based on their idea of acceptable recall and the desired probability which databases to include in their searches. 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. MEDLINE is a great resource for medical . Fifty-one of these journals are UK publications. It is likely that topical differences in systematic reviews may impact whether databases such as Web of Science and Google Scholar add value to the review. Of the combinations of two databases, Embase and MEDLINE had the best results (92.8%). For 55 reviews, we determined the domain.
