sharing sensitive information, make sure youre on a federal 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. This search is then optimized. From a set of 200 recent SRs identified via PubMed, we analyzed the databases that had been searched. Careers. official website and that any information you provide is encrypted Based on our findings, this combination achieves acceptable recall about half the time (47%). 2 - CRzB:x{m9*eZvs@~&AWSiwY5a%Ofn(ehsVvu-O#Y+(t &c-SvTtFg *@WsWTy._,i@R(ay>EK4J=z}8S6(Cw viV%Q%bs-&{ 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.

The calculation is shown in Table5. Reviews included in the research. This study also highlights once more that searching databases alone is, nevertheless, not enough to retrieve all relevant references. However, whether an article is present in a database may not translate to being found by a search in that database. For reviews where RCTs are the desired study design, Cochrane CENTRAL may be similarly useful. The database includes all charts, diagrams, graphs, tables, photos, and other graphical elements essential to medical research. Table3 displays the number of unique results retrieved for each single database. 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]. For each review that we investigated, we determined what the recall was for all possible different database combinations of the most important databases. In both these reviews, the topic was highly related to the topic of the database. We estimate more than 50% of reviews that include more study types than RCTs would miss more than 5% of included references if only traditional combination of MEDLINE, Embase, and Cochrane CENTAL is searched. J Kerman Univ Med Sci. The one review where it was insufficient was about alternative medicine, specifically meditation and relaxation therapy, where one of the missed studies was published in the Indian Journal of Positive Psychology. Article 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. Other databases that we identified as essential for good recall were searched much less frequently; Embase was searched in 61% and Web of Science in 35%, and Google Scholar was only used in 10% of all reviews. Because precision is defined as the number of relevant references divided by the number of total results, we see a strong correlation with the total number of results. The three databases were searched for citations on topics selected by three nurse researchers and the results were compared. Unauthorized use of these marks is strictly prohibited. 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 . https://doi.org/10.1186/s13643-017-0644-y, DOI: https://doi.org/10.1186/s13643-017-0644-y. 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. 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. The purpose of this research was to determine which of three databases, CINAHL, EMBASE or MEDLINE, should be accessed when researching nursing topics. Psychology & Behavioral Sciences Collectionis a comprehensive database covering information concerning topics in emotional and behavioral characteristics, psychiatry & psychology, mental processes, anthropology, and observational & experimental methods.

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 database itself is unfiltered, but includes many filtered items like systematic reviews. When the number of references from other databases was low, we expected the total number of potential relevant references to be low. Searching additional databases except PubMed are necessary for a systematic review. In that case, Google Scholar might add value by searching the full text of articles. 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. MEDLINE did find unique references that had not been found in Embase, although our searches in Embase included all MEDLINE records. The reviews covered a wide variety of disease, none of which was present in more than 12% of the reviews. Performance was measured using recall, precision, and number needed to read. For four out of five systematic reviews that limited to randomized controlled trials (RCTs) only, the traditional combination retrieved 100% of all included references. Accessibility 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. J Med Libr Assoc. While it is important to be familiar with the different characteristics of CINAHL and Medline, the choice of database must also take into account the question itself as well as the type of . Note: With this limiter you will need to evaluate your results to determine what type of evidence each article contains. This research goes beyond retrospectively assessed coverage to investigate real search performance in databases. Researchers planning a systematic review generally perform one review, and they need to estimate the probability that they may miss relevant articles in their search. Provided by the Springer Nature SharedIt content-sharing initiative. For the search of nursing care literature on a medical condition, it . Of the individual databases, Embase had the highest overall recall (85.9%). This is the world's largest full text psychology database offering full text coverage for nearly 400 journals. 2015;68:61726. 2005 Jan;58(1):20-5. doi: 10.1016/j.jclinepi.2004.06.001.

This Spanish language database contains full text for 130 peer-reviewed medical journals in native Spanish. 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%. endobj The sum of all these values is the total probability of acceptable recall in the random sample. Halladay CW, Trikalinos TA, Schmid IT, Schmid CH, Dahabreh IJ. 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. Database designers and developers, the data and database administrators and end-users must understand this functionality to take full advantage of it. Search Limits. Of the 11 references included in this review, one was found only in Google Scholar and one only in Web of Science. Our study shows that, to reach maximum recall, searches in systematic reviews ought to include a combination of databases. 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. Many of the reviews were initiated by members of the departments of surgery and epidemiology. 2 0 obj The Web of Science database is considered a preferred data source for bibliometric analysis due to the comprehensive information and multi-disciplinary data of literature provided (Falagas et al . Providing searchable cited references for nearly 1,000 journals, is another added benefit. 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.

Until 2016, the most complete MEDLINE selection in Ovid still lacked the electronic publications that were already available in PubMed. 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%. [26] found that Cochrane CENTRAL included 95% of all RCTs included in the reviews investigated. mOkV1#8 (uTb We copied from the MeSH tree the top MeSH term directly below the disease category or, in to case of the intervention, directly below the therapeutics MeSH term. 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.
