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. In general, we use the first 200 references as sorted in the relevance ranking of Google Scholar. The contribution of databases to the results of systematic reviews: a cross-sectional study. Syst Rev. 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.

Because of this major limitation, the question of which databases are necessary to retrieve all relevant references for a systematic review remains unanswered. There are disadvantages to using multiple databases. 2023 BioMed Central Ltd unless otherwise stated. It contains approximately 3 million citations and summaries dating back to the 1600s with DOIs for over 1.4 million records.

References to the systematic reviews published by Erasmus MC authors that were included in the research. We see that reviewers rarely use Web of Science and especially Google Scholar in their searches, though they retrieve a great deal of unique references in our reviews. J Med Libr Assoc. Sixteen percent of the included references (291 articles) were only found in a single database; Embase produced the most unique references (n=132). MeSH The full list of the 81 unique titles in BNI when compared with any version of CINAHL and their country of publication are reproduced in Appendix S1.

The searcher in the case of all 58 systematic reviews is an experienced biomedical information specialist. 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. 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.

The skills and experience of the searcher are one of the most important aspects in the effectiveness of systematic review search strategies [23,24,25]. 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. 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. Did you know that with a free Taylor & Francis Online account you can gain access to the following benefits?

What is considered acceptable recall for systematic review searches is open for debate and can differ between individuals and groups. Ahntastic Adventures in Silicon Valley For nine of these reviews, all the studies that had been included in the final synthesis were available in the CINAHL database, so it could have been possible to identify all the included studies using just this one database, while for an additional 21 reviews (49 %), 80 % or more of the included studies were available in CINAHL.

Searching only Embase produced an NNR of 57 on average, whereas, for the optimal combination of four databases, the NNR was 73. Whether Embase and Web of Science can be replaced by Scopus remains uncertain. The collection contains thousands of proprietary, copyrighted images depicting normal anatomy, physiology, embryology, and histology, as well as the web's largest repository of reference illustrations depicting surgery, trauma, pathology, diseases and conditions. Although we searched PubMed as supplied by publisher separately from MEDLINE in Ovid, we combined the included references of these databases into one measurement in our analysis. MEDLINE did find unique references that had not been found in Embase, although our searches in Embase included all MEDLINE records. Database designers and developers, the data and database administrators and end-users must understand this functionality to take full advantage of it. [17] found the added value of other databases only for newer, non-indexed references. Rethlefsen ML, Farrell AM, Osterhaus Trzasko LC, Brigham TJ. WB and ML analyzed the data.

One explanation for our finding may be that if the research question is very specific, the topic of research might not always be mentioned in the title and/or abstract. 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. To identify whether our searches had found the included references, and if so, from which database(s) that citation was retrieved, each included reference was located in the original corresponding EndNote library using the first author name combined with the publication year as a search term for each specific relevant publication. HHS Vulnerability Disclosure, Help 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. vD@3h0MusH%|$e5Cl|Pl aWEEv~3v:hq`M 1LYi"eo*mZTmiMBV(']YJYa:{Xk4S9Tj-MLNAN}V%!U]h*us(5i:8}takdd-~^3I+LR0mkb4Kb3tTl! disadvantages of cinahl database .

Based on the record numbers of the search results in EndNote, we determined from which database these references came. A systematic approach to searching: how to perform high quality literature searches more efficiently. A case study using a systematic review of frozen shoulder management.

The other authors declare no competing interests. Additionally, search strategies are limited to a maximum of 256 characters, which means that creating a thorough search strategy can be laborious. When the number of references from other databases was low, we expected the total number of potential relevant references to be low. From: Complementary Therapies for Physical Therapy, 2008 View all Topics Add to Mendeley Springer Nature. 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. Subject-specific databases like PsycINFO only added unique references to a small percentage of systematic reviews when they had been used for the search. 2005 Jan 8;5:2. doi: 10.1186/1471-2288-5-2. https://doi.org/10.1186/s13643-017-0644-y, DOI: https://doi.org/10.1186/s13643-017-0644-y. <>/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>> WB drafted the first manuscript, which was revised critically by the other authors.
