J Clin Epidemiol. The searcher in the case of all 58 systematic reviews is an experienced biomedical information specialist. Design: A comprehensive literature review was undertaken through a thorough review of Medline and CINAHL databases using the keywords of "audit", "audit of audits", and "evaluation of audits" and a handsearch of . WB designed the searches used in this study and gathered the data. del rio rams . Sixteen percent of the included references (291 articles) were only found in a single database; Embase produced the most unique references (n=132). A pragmatic evaluation of a new method for librarian-mediated literature searches for systematic reviews. MEDLINE did find unique references that had not been found in Embase, although our searches in Embase included all MEDLINE records. 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%. The recall of the database combinations was calculated over all included references retrieved by any database. Figure5 shows the improvement of precision for 15 databases and database combinations. 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. This research goes beyond retrospectively assessed coverage to investigate real search performance in databases. endobj If Erasmus MC authors had conducted more reviews that included only RCTs, Cochrane CENTRAL might have added more unique references. Those databases that contributed the most unique included references were then considered candidate databases to determine the most optimal combination of databases in the further analyses. This number however is not an answer to the question of a researcher performing a systematic review, regarding which databases should be searched. McGowan J, Sampson M. Systematic reviews need systematic searchers. 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). The three databases were searched for citations on topics selected by three nurse researchers and the results were compared. BMC Med Res Methodol. These results may not be generalizable to other studies for other reasons. Subirana M, Sol I, Garcia JM, Gich I, Urrtia G. J Clin Epidemiol.

Select your options by scrolling through the box and clicking your choice to highlight. Quick Answer: What are Boolean operators? 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. Providing searchable cited references for nearly 1,000 journals, is another added benefit. 2011;91:1907. 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. 5 Howick Place | London | SW1P 1WG. The purpose of this research was to determine which of three databases, CINAHL, EMBASE or MEDLINE, should be accessed when researching nursing topics. Nevertheless others have concluded that a single database is not sufficient to retrieve all references for systematic reviews [18, 19]. By closing this message, you are consenting to our use of cookies. PubMed Central ProQuest Nursing & Allied Health Source provides abstracting and indexing for more than 1,050 titles, with over 875 titles in full-text, plus more than 12,300 full text dissertations representing the most rigorous scholarship in nursing and related fields. The three databases were searched for citations on topics selected by three nurse researchers and the results were compared. [26] found that Cochrane CENTRAL included 95% of all RCTs included in the reviews investigated. 2014;30:1738. Res Synth Methods. Depending on the goal of the search, different measures may be optimized. The one review where it was insufficient was about alternative medicine, specifically meditation and relaxation therapy, where one of the missed studies was published in the Indian Journal of Positive Psychology. Over a third of the reviews were therapeutic, while slightly under a quarter answered an etiological question. Published reviews were included if the search strategies and results had been documented at the time of the last update and if, at minimum, the databases Embase, MEDLINE, Cochrane CENTRAL, Web of Science, and Google Scholar had been used in the review. There is an overlap in the journals indexed by these two databases. People also read lists articles that other readers of this article have read. This shows that many database searches missed relevant references. kON0=ArP35x`*[r(DYVBa9BJ2w\LueOJ=i.dR;mmP/P All searches in this study were developed and executed by W.M.B. A fast and easy research tool for nursing and allied health professionals with access to content coverage including over 50 nursing specialties, speech and language pathology, nutrition, general health and medicine and . 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? Comparison of CINAHL, EMBASE, and MEDLIN . Medicine, Dentistry, Nursing & Allied Health. We identified all included references that were uniquely identified by a single database. Table3 displays the number of unique results retrieved for each single database. Wright K, Golder S, Lewis-Light K. What value is the CINAHL database when searching for systematic reviews of qualitative studies? Bramer WM, de Jonge GB, Rethlefsen ML, Mast F, Kleijnen J. 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. If this resulted in extraneous results, the search was subsequently limited using a distinct part of the title or a second author name. 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).

We calculated the ratio between the number of results found when searching all databases, including databases not included in our analyses, such as Scopus, PsycINFO, and CINAHL, and the number of results found searching a selection of databases. Note: You can use OR to link together your synonyms, or related words, in a search box, allowing the database to search more broadly. A total of 292 (17%) references were found by only one database. This database also offers indexing and abstracts for more than 10,100 journals and a total of 10,600 publications including monographs, reports, conference proceedings, etc. We did not investigate whether the loss of certain references had resulted in changes to the conclusion of the reviews. On this page you will learn how to limit your results in CINAHL to: Case studies may be prospective (in which criteria are established and cases fitting the criteria are included as they become available) or retrospective (in which criteria are established and cases are selected from historical records for inclusion in the study). A multi-disciplinary database, with more than 6,100 full-text periodicals, including more than 5,100 peer-reviewed journals. In 73 of these, the searches and results had been documented by the first author of this article at the time of the last search. Michaleff ZA, Costa LO, Moseley AM, Maher CG, Elkins MR, Herbert RD, Sherrington C. CENTRAL, PEDro, PubMed, and EMBASE are the most comprehensive databases indexing randomized controlled trials of physical therapy interventions. 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. https://doi.org/10.1186/s13643-017-0644-y, DOI: https://doi.org/10.1186/s13643-017-0644-y. We find that Embase is critical for acceptable recall in a review and should always be searched for medically oriented systematic reviews. From: Complementary Therapies for Physical Therapy, 2008 View all Topics Add to Mendeley Searching only Embase produced an NNR of 57 on average, whereas, for the optimal combination of four databases, the NNR was 73. 2014;67:11929. 2014;21:34354. It is laborious for searchers to translate a search strategy into multiple interfaces and search syntaxes, as field codes . Abbreviations: EM Embase, ML MEDLINE, WoS Web of Science, GS Google Scholar. This can be offset, as noted above, by going to the EBSCOhost (Health) package of databases. The Cochrane Handbook, for example, recommends the use of at least MEDLINE and Cochrane Central and, when available, Embase for identifying reports of randomized controlled trials [7]. In 23 reviews included in this research, Scopus was searched. Part of Beckles Z, Glover S, Ashe J, Stockton S, Boynton J, Lai R, Alderson P.

Psychology & Behavioral Sciences Collectionis a comprehensive database covering information concerning topics in emotional and behavioral characteristics, psychiatry & psychology, mental processes, anthropology, and observational & experimental methods. Complexity The provision of the functionality we expect of a good DBMS makes the DBMS an extremely complex piece of software. 2015;68:61726. For a sample of 200 recently published systematic reviews, we calculated how many had used enough databases to ensure 95% recall. 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. 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. The purpose of this research was to determine which of three databases, CINAHL, EMBASE or MEDLINE, should be accessed when researching nursing topics. 1996 Jul;84(3):402-8. When looking at the overall recall, the combination of Embase and MEDLINE and either Google Scholar or Web of Science could be regarded sufficient with 96% recall. Wilkins T, Gillies RA, Davies K. EMBASE versus MEDLINE for family medicine searches: can MEDLINE searches find the forest or a tree? CINAHL provided the majority of relevant articles for the second search, on computers and privacy, but inclusion of MEDLINE and EMBASE enhanced retrieval somewhat. The databases avail-able include the Cochrane Collaboration, Medline (in various forms such as PubMed), Best Evidence10and Embase.The most widely used and most often recom-mended database isMedline. A nursing qualitative systematic review required MEDLINE and CINAHL for study identification. how to send secure email attachments in gmail. Stevinson C, Lawlor DA. 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. <>>> Consequently . It is likely caused by difference in thesaurus terms that were added, but further analysis would be required to determine reasons for not finding the MEDLINE records in Embase. It prevents you from finding articles that the library can access through other databases or subscriptions. Clipboard, Search History, and several other advanced features are temporarily unavailable. In this case, the number of hits from Google Scholar was limited to 100. %PDF-1.5 These could be retrieved by searching PubMed with the subset as supplied by publisher. The content is solely the responsibility of the authors and does not necessarily represent the official views of the National Institutes of Health. Special topics databases such as CINAHL and PsycINFO should be added if the topic of the review directly touches the primary focus of a specialized subject database, like CINAHL for focus on nursing and allied health or PsycINFO for behavioral sciences and mental health. Ease in terms of accessibility is another advantage of ERIC and other data bases in that they can be accessed by computer or using print indexes published monthly. In short, the method consists of an efficient way to combine thesaurus terms and title/abstract terms into a single line search strategy. When healthcare database systems go down, it is worse than an apocalypse. Until 2016, the most complete MEDLINE selection in Ovid still lacked the electronic publications that were already available in PubMed. 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. Stroke. Literature search parameters marginally improved the pooled estimate accuracy for ultrasound in detecting deep venous thrombosis. 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. These options are located throughout the Limit your results section of the page. Google Scholar adds relevant articles not found in the other databases, possibly because it indexes the full text of all articles. 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.

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. For each published systematic review, we extracted the references of the included studies. disadvantages of cinahl database . Our conclusion that Web of Science and Google Scholar are needed for completeness has not been shared by previous research. Within systematic reviews, when searching for relevant references, it is advisable to use multiple databases. Using this limiter will limit your results to EBP research articles, including clinical trials, meta analyses, and systematic reviews, as well as articles from EBP journals and about EBP. They are usually one of the easiest study types to find in any nursing or medical database. The four databases that had retrieved the most unique references (Embase, MEDLINE, Web of Science, and Google Scholar) were investigated individually and in all possible combinations (see Table4). CAUTION Do not use Linked Full Text Limit. Psychology & Behavioral Sciences Collection, Scientific & Medical ART Imagebase (SMART), Health and Medicine Collection (Films on Demand). 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. Ws"30z@+RY{"+NTzXnnf.ote{X-C.!0rxY_K+LSA12"fDAKJtk/FQS. While previous studies determined the coverage of databases, we analyzed the actual retrieval from the original searches for systematic reviews. Fifty-one of these journals are UK publications. Health Inf Libr J. Asterisk indicates that the recall of all databases has been calculated over all included references. Accessibility The .gov means its official. Register to receive personalised research and resources by email. Nearly 5,000 journals are read and their individual articles indexed and added to the MEDLINE database, which contains information about over 12 million journal articles. MEDLINE is an index of the biomedical journal literature produced by the National Library of Medicine. Of these, 84 references (4.6%) had not been retrieved by our database searches and were not included in our analysis, leaving in total 1746 references. Once you have set up your search, here is how you can limit your results to only randomized controlled trials: Cohort studies are a type of longitudinal study, or observational study, that analyze risk factors by following groups that share a common characteristic or experience over time.

Disclaimer. ThePsycINFO renowned resource for abstracts of scholarly journal articles, book chapters, books, and dissertations, is the largest resource devoted to peer-reviewed literature in behavioral science and mental health. 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%. 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. This filter can be usedfind articles that are clinically-sound. Lastly, we checked whether the reviews described limiting their included references to a particular study design.

The comparative recall of Google Scholar versus PubMed in identical searches for biomedical systematic reviews: a review of searches used in systematic reviews. Please enable it to take advantage of the complete set of features! The database combinations with the highest recall did not reduce the total number of results by large margins. It is likely that topical differences in systematic reviews may impact whether databases such as Web of Science and Google Scholar add value to the review. Some concluded that searching only one database can be sufficient as searching other databases has no effect on the outcome [16, 17]. 2023 BioMed Central Ltd unless otherwise stated. Ross-White A, Godfrey C. Is there an optimum number needed to retrieve to justify inclusion of a database in a systematic review search? 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. Evid Based Libr Inf Pract. For reviews where RCTs are the desired study design, Cochrane CENTRAL may be similarly useful. McKibbon KA, Haynes RB, Dilks CJW, Ramsden MF, Ryan NC, Baker L, Flemming T, Fitzgerald D.

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. Is the coverage of Google Scholar enough to be used alone for systematic reviews. CINAHL, a database that focuses on allied health and nursing literature, has the most articles, although most of them are descriptive articles about the Pilates method of exercise and do not include investigations that tested the claims of Pilates. endobj using CINAHL alone.

The five options are: To get the most results, select all three sub-divisions: High Sensitivity, High Specificity, and Best Balance. Improving search efficiency for systematic reviews of diagnostic test accuracy: an exploratory study to assess the viability of limiting to MEDLINE, EMBASE and reference checking. 2016;87:713. Prior research on database importance for systematic reviews has looked primarily at whether included references could have theoretically been found in a certain database, but most have been unable to ascertain whether the researchers actually found the articles in those databases [10, 12, 16, 17, 26]. This study also highlights once more that searching databases alone is, nevertheless, not enough to retrieve all relevant references. Lawrence DW. However, searching databases is laborious and time-consuming, as syntax of search strategies are database specific. Article 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. We selected the domain from a pre-defined set of broad domains, including therapy, etiology, epidemiology, diagnosis, management, and prognosis. 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. Since the introduction of the more complete MEDLINE collection Epub Ahead of Print, In-Process & Other Non-Indexed Citations, and Ovid MEDLINE, the need to separately search PubMed as supplied by publisher has disappeared. 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.
