We calculated the recall for individual databases and databases in all possible combination for all reviews included in the research. 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. endobj 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. Some reviewers might accept a potential loss of 5% of relevant references; others would want to pursue 100% recall, no matter what cost. 1 0 obj A nursing qualitative systematic review required MEDLINE and CINAHL for study identification. Bramer WM, Giustini D, Kramer BM, Anderson PF. 2 for the comparison of the recall of Embase, MEDLINE, and Cochrane CENTRAL per review for all identified domains. Inj Prev.

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]. Asterisk indicates that the recall of all databases has been calculated over all included references. 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. Based on the number of results per database both before and after deduplication as recorded at the time of searching, we calculated the ratio between the total number of results and the number of results for each database and combination. The calculation is shown in Table5. Furthermore, it is time-consuming for reviewers who have to screen more, and likely irrelevant, titles and abstracts.

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. Optimal database combinations for literature searches in systematic reviews: a prospective exploratory study. endobj Google Scholar. Provided by the Springer Nature SharedIt content-sharing initiative. Aagaard T, Lund H, Juhl C. Optimizing literature search in systematic reviewsare MEDLINE, EMBASE and CENTRAL enough for identifying effect studies within the area of musculoskeletal disorders?

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.

Unauthorized use of these marks is strictly prohibited. j 'o The recall of the database combinations was calculated over all included references retrieved by any database. We found that two databases previously not recommended as essential for systematic review searching, Web of Science and Google Scholar, were key to improving recall in the reviews we investigated. <>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/Annots[ 9 0 R 10 0 R] /MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> Article See Table1 for definitions of these measures.

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. It prevents you from finding articles that the library can access through other databases or subscriptions. 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. The sum of all these values is the total probability of acceptable recall in the random sample. A case study using a systematic review of frozen shoulder management. In the other 48%, the recall by Scopus was suboptimal, in one occasion as low as 38%. Most articles on this topic draw their conclusions based on the coverage of databases [14].

Unique references were included articles that had been found by only one database search. Depending on the goal of the search, different measures may be optimized. 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%. If this resulted in extraneous results, the search was subsequently limited using a distinct part of the title or a second author name. There are also fewer of them, and they can be harder to find.
