A systematic approach to searching: how to perform high quality literature searches more efficiently. We searched PubMed in July 2016 for all reviews published since 2014 where first authors were affiliated to Erasmus MC, Rotterdam, the Netherlands, and matched those with search registrations performed by the medical library of Erasmus MC. Kr Mo@h(fW"\x| Tu?g n=~?@(wg Eighty-one journals are uniquely indexed in BNI compared with all versions of CINAHL. 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. 2019 Aug;21(4):853-878. doi: 10.1007/s10903-018-0816-4.

Figure4 shows the distribution of this value for individual reviews. 2006 Jul;59(7):710-4. doi: 10.1016/j.jclinepi.2005.09.013. Due to the nature and distribution of the nursing literature, it is especially important for the searcher to understand and respond to the focus of the researcher. According to our data, PubMeds as supplied by publisher subset retrieved 12 unique included references, and it was the most important addition in terms of relevant references to the four major databases. https://doi.org/10.1186/s13643-017-0644-y, DOI: https://doi.org/10.1186/s13643-017-0644-y. 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.

Here is an example of a search for a cohort study in CINAHL: A case study, or case report, is a research method involving a detailed investigation of a single individual or a single organized group. Syst Rev. For the search of nursing care literature on a medical condition, it was helpful to search both CINAHL and MEDLINE. 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 . 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%. However, Embase is only accessible via a paid subscription, which generally makes it challenging for review teams not affiliated with academic medical centers to access. and transmitted securely. 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%. This database provides nearly 550 scholarly full text journals focusing on many medical disciplines. We find that Embase is critical for acceptable recall in a review and should always be searched for medically oriented systematic reviews. Based on our findings, this combination achieves acceptable recall about half the time (47%). J Clin Epidemiol. This study also highlights once more that searching databases alone is, nevertheless, not enough to retrieve all relevant references. The database combinations with the highest recall did not reduce the total number of results by large margins. Are MEDLINE searches sufficient for systematic reviews and meta-analyses of the diagnostic accuracy of depression screening tools? 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. In this case, the number of hits from Google Scholar was limited to 100. Select an option by finding it in the list and clicking on it (it will then be highlighted).

"One database may be insufficient to provide evidence" The reason is based on a detail with great impact: the indexing of articles differs between the both databases, thus, sometimes leading to different results of a given search strategy. 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. Ignoring one or more of the databases that we identified as the four key databases will result in more precise searches with a lower number of results, but the researchers should decide whether that is worth the >increased probability of losing relevant references. 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. References to the systematic reviews published by Erasmus MC authors that were 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. 2 for the comparison of the recall of Embase, MEDLINE, and Cochrane CENTRAL per review for all identified domains. Note: Putting quotation marks around phrases tells the database to search for these words as a phrase and not as individual words. However, whether an article is present in a database may not translate to being found by a search in that database. This site needs JavaScript to work properly.

Though we suspect that searchers who are not information specialists or librarians would have a higher possibility of less well-constructed searches and searches with lower recall, even highly trained searchers differ in their approaches to searching. 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. sharing sensitive information, make sure youre on a federal Optimal database combinations for literature searches in systematic reviews: a prospective exploratory study. Bramer WM, de Jonge GB, Rethlefsen ML, Mast F, Kleijnen J. Although Embase covers MEDLINE, it apparently does not index every article from MEDLINE. Some concluded that searching only one database can be sufficient as searching other databases has no effect on the outcome [16, 17]. 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. CAS Biomedical databases are usually the initial source of information regarding the use, performance and dis-advantages of a diagnostic test. }UCby^4(-\SHU1B CPn(ULF{fUUog].[>~si|F] mykK+NGz Films Media Group serves the education community through its four brands: Films for the Humanities and Sciences, Cambridge Educational, Meridian Education, and Shopware.

Comput Biomed Res. There are disadvantages to using multiple databases. 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 . Google Scholar. The complete results from all databases used for each of the systematic reviews were imported into a unique EndNote library upon search completion and saved without deduplication for this research. For the databases that retrieved the most unique included references, we calculated the number of references retrieved (after deduplication) and the number of included references that had been retrieved by all possible combinations of these databases, in total and per review. The researchers that requested the search received a deduplicated EndNote file from which they selected the references relevant for inclusion in their systematic review. A review of meta-analyses.
