The combination of Embase, MEDLINE, Web of Science Core Collection, and Google Scholar performed best, achieving an overall recall of 98.3 and 100% recall in 72% of systematic 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. 4 and 5. Within systematic reviews, when searching for relevant references, it is advisable to use multiple databases. For the search of nursing care literature on a medical condition, it was helpful to search both CINAHL and MEDLINE. WB and ML analyzed the data. 2016;87:713. However, when looking at individual reviews, the probability of missing more than 5% of included references found through database searching is 33% when Google Scholar is used together with Embase and MEDLINE and 30% for the Web of Science, Embase, and MEDLINE combination. Since these studies have a long-term component, they promote abetter quality of evidence than a shorter study. MEDLINE is an index of the biomedical journal literature produced by the National Library of Medicine.

Thedatabase itself is unfiltered, but includes many filtered items like systematic reviews. 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. Nursing: Indexes & Databases. del rio rams . In the other 48%, the recall by Scopus was suboptimal, in one occasion as low as 38%. Librarian co-authors correlated with higher quality reported search strategies in general internal medicine systematic reviews. 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. [17] found the added value of other databases only for newer, non-indexed references. Hartling L, Featherstone R, Nuspl M, Shave K, Dryden DM, Vandermeer B. Of the individual databases, Embase had the highest overall recall (85.9%). PubMed Central In general, searches are developed in MEDLINE in Ovid (Ovid MEDLINE In-Process & Other Non-Indexed Citations, Ovid MEDLINE Daily and Ovid MEDLINE, from 1946); Embase.com (searching both Embase and MEDLINE records, with full coverage including Embase Classic); the Cochrane Central Register of Controlled Trials (CENTRAL) via the Wiley Interface; Web of Science Core Collection (hereafter called Web of Science); PubMed restricting to records in the subset as supplied by publisher to find references that not yet indexed in MEDLINE (using the syntax publisher [sb]); and Google Scholar.

The reviews covered a wide variety of disease, none of which was present in more than 12% of the 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? At Erasmus MC, search strategies for systematic reviews are often designed via a librarian-mediated search service. Some reviewers might accept a potential loss of 5% of relevant references; others would want to pursue 100% recall, no matter what cost. 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. Literature search parameters marginally improved the pooled estimate accuracy for ultrasound in detecting deep venous thrombosis.

Searching only Embase produced an NNR of 57 on average, whereas, for the optimal combination of four databases, the NNR was 73. 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]. Figure4 shows the distribution of this value for individual reviews. endobj The major strength of our paper is that it is the first large-scale study we know of to assess database performance for systematic reviews using prospectively collected data. Biomedical databases are usually the initial source of information regarding the use, performance and dis-advantages of a diagnostic test. All searches in this study were developed and executed by W.M.B. If Erasmus MC authors had conducted more reviews that included only RCTs, Cochrane CENTRAL might have added more unique references. Bookshelf Health Inf Libr J. 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%. 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. Nevertheless others have concluded that a single database is not sufficient to retrieve all references for systematic reviews [18, 19]. Correspondence to Health Inf Libr J. Syst Rev. To determine how searching multiple databases affected precision, we calculated for each combination the ratio between the original precision, observed when all databases were searched, and the precision calculated for different database combinations. This search is then optimized. Differences in thesaurus terms between databases add another significant burden for translation. The other study from the Journal of Advanced Nursing is indexed in MEDLINE and Embase but was only retrieved because of the addition of KeyWords Plus in Web of Science. A case study using a systematic review of frozen shoulder management. 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. We have not yet gathered enough data to be able to make a full comparison between Embase and Scopus. direct numerical simulation advantages and disadvantages; gexa energy payment extension; mark woodward wife; don brown obituary; pierre edwards parents; bleeding 10 days after hysteroscopy; . CINAHL provided the majority of relevant articles for the second search, on computers and privacy, but inclusion of MEDLINE and EMBASE enhanced retrieval somewhat. A secondary aim is to investigate the current practice of databases searched for published reviews. The higher recall from adding extra databases came at a cost in number needed to read (NNR).
