Many of the articles reporting on previous research concluded that one database was able to retrieve most included references. 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. Most articles on this topic draw their conclusions based on the coverage of databases [14]. 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. We assessed the frequency at which databases and combinations would achieve varying levels of recall (i.e., 95%). disadvantages of cinahl database . Using similar calculations, also shown in Table5, we estimated the probability that 100% of relevant references were retrieved is 23%. The information specialists of Erasmus MC developed an efficient method that helps them perform searches in many databases in a much shorter time than other methods. The contribution of databases to the results of systematic reviews: a cross-sectional study. Identify resources at your library and in the collections of the worlds libraries. 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. sharing sensitive information, make sure youre on a federal However, for one review of this domain, the recall was 82%.

Preston L, Carroll C, Gardois P, Paisley S, Kaltenthaler E. Syst Rev. Are MEDLINE searches sufficient for systematic reviews and meta-analyses of the diagnostic accuracy of depression screening tools? J Clin Epidemiol. From a set of 200 recent SRs identified via PubMed, we analyzed the databases that had been searched. 2011;91:1907. Articles that are indexed with a set of identified thesaurus terms, but do not contain the current search terms in title or abstract, are screened to discover potential new terms. Consequently . Based on these calculations, we estimate that the probability that this random set of reviews retrieved more than 95% of all possible included references was 40%. Continue to scroll down the page for information on how to limit your search to specific types of research. While previous studies determined the coverage of databases, we analyzed the actual retrieval from the original searches for systematic reviews. Subirana M, Sol I, Garcia JM, Gich I, Urrtia G. J Clin Epidemiol. Of the combinations of two databases, Embase and MEDLINE had the best results (92.8%). Because this is a novel finding, we cannot conclude whether it is due to our dataset or to a generalizable principle. Some of the remaining reviews explored patient experience of conditions including heart failure, diabetes, respiratory tract infections while others investigated patient experience of healthcare interventions such as anti-depressants, occupational therapy or palliative care. Some reviewers might accept a potential loss of 5% of relevant references; others would want to pursue 100% recall, no matter what cost.

Using the prospectively recorded results and the studies included in the publications, we calculated recall, precision, and number needed to read for single databases and databases in combination. Ahmadi M, Ershad-Sarabi R, Jamshidiorak R, Bahaodini K. Comparison of bibliographic databases in retrieving information on telemedicine. A nursing qualitative systematic review required MEDLINE and CINAHL for study identification. Of all reviews in which we searched CINAHL and PsycINFO, respectively, for 6 and 9% of the reviews, unique references were found. Some concluded that searching only one database can be sufficient as searching other databases has no effect on the outcome [16, 17]. Sixteen percent of the included references (291 articles) were only found in a single database; Embase produced the most unique references (n=132). 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. Searching additional databases except PubMed are necessary for a systematic review. Cochrane CENTRAL is absent from the table, as for the five reviews limited to randomized trials, it did not add any unique included references. endobj There are also fewer of them, and they can be harder to find. Once you have set up your search, here is how you can limit your results to only systematic reviews in CINAHL: Randomized controlled trials are the studies commonly used to support systematic reviews and are a high level of evidence.

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. 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%. del rio rams . However, whether an article is present in a database may not translate to being found by a search in that database. Where should the pharmacy researcher look first? The database itself is unfiltered, but includes many filtered items like systematic reviews. Ross-White A, Godfrey C. Is there an optimum number needed to retrieve to justify inclusion of a database in a systematic review search? 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 Cochrane Handbook recommends searching MEDLINE, Cochrane CENTRAL, and Embase for systematic reviews of RCTs. 2016;87:713. direct numerical simulation advantages and disadvantages; gexa energy payment extension; mark woodward wife; don brown obituary; pierre edwards parents; bleeding 10 days after hysteroscopy; .

Improvement of precision was calculated as the ratio between the original precision from the searches in all databases and the precision for each database and combination. Although Embase covers MEDLINE, it apparently does not index every article from MEDLINE. As our research is performed on systematic reviews, the main performance measure is recall. WB, JK, and OF designed the study. 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. PMC 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%. Article BMC Med Res Methodol. The aim of our research is to determine the combination of databases needed for systematic review searches to provide efficient results (i.e., to minimize the burden for the investigators without reducing the validity of the research by missing relevant references). 2015 Jun 26;4:82. doi: 10.1186/s13643-015-0074-7.

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. Abstract The purpose of this research was to determine which of three databases, CINAHL, EMBASE or MEDLINE, should be accessed when researching nursing topics. California Privacy Statement, 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). 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. [17] found the added value of other databases only for newer, non-indexed references. See Fig. Because these studies based on retrospective analysis of database coverage do not account for the searchers abilities, the actual findings from the searches performed, and the indexing for particular articles, their conclusions lack immediate translatability into practice. PubMed Central Therefore, for this research, a total of 58 systematic reviews were analyzed. 2015;68:107684. For a sample of 200 recently published systematic reviews, we calculated how many had used enough databases to ensure 95% recall. A total of 58 published systematic reviews were included, totaling 1746 relevant references identified by our database searches, while 84 included references had been retrieved by other search methods. Figure5 shows the improvement of precision for 15 databases and database combinations. The higher recall from adding extra databases came at a cost in number needed to read (NNR). Of course, the loss of a minor non-randomized included study that follows the systematic reviews conclusions would not be as problematic as losing a major included randomized controlled trial with contradictory results. Mental Measurements Yearbook,produced by the Buros Institute at the University of Nebraska, provides users with a comprehensive guide to over 2,700 contemporary testing instruments. 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. 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. 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. 2 0 obj Our conclusion that Web of Science and Google Scholar are needed for completeness has not been shared by previous research.

One hundred and fifty-nine journals are uniquely indexed in BNI compared with the basic version of CINAHL. Because of this major limitation, the question of which databases are necessary to retrieve all relevant references for a systematic review remains unanswered. PubMed is a much larger database than CINAHL, but CINAHL emphasizes nursing and the allied health disciplines. 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. These results may not be generalizable to other studies for other reasons. An overview of the broad topical categories covered in these reviews is given in Table2.
