This search was used in earlier research [21]. 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. Phys Ther. PubMed Evid Based Libr Inf Pract. Wilkins T, Gillies RA, Davies K. EMBASE versus MEDLINE for family medicine searches: can MEDLINE searches find the forest or a tree? We identified all included references that were uniquely identified by a single database. There are disadvantages to using multiple databases. 9v[-[TkBaly.Ja%"uu'Nd&nNSevS}VXcS63#qN By using this website, you agree to our Figure1 shows the percentages of reviews where a certain database combination led to a certain recall. >/- 8CqD 0:J AT~Xr Bx:.}U_y>gEdUug1tXA ed! 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. An overview of the broad topical categories covered in these reviews is given in Table2. -$P*C! 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. When the number of references from other databases was low, we expected the total number of potential relevant references to be low. Using both Web of Science and Google Scholar in addition to MEDLINE and Embase increased the overall recall to 98.3%. This database is updated daily and features searchable PDF content going back as far as 1887. In addition to journal articles, CINAHL includes books, book chapters, dissertations, and computer programs. 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. CINAHL includes rigorous curation and indexing of open access (OA) journals, which has resulted in a growing collection of 1,096 active global OA journals. Google Scholar adds relevant articles not found in the other databases, possibly because it indexes the full text of all articles. volume6, Articlenumber:245 (2017) Almost all reviews (97%) reported a search in MEDLINE. Most reviews did not limit to certain study designs, 9% limited to RCTs only, and another 9% limited to other study types. Rethlefsen ML, Farrell AM, Osterhaus Trzasko LC, Brigham TJ. Figure4 shows the distribution of this value for individual reviews. Searching Google Scholar is challenging as it lacks basic functionality of traditional bibliographic databases, such as truncation (word stemming), proximity operators, the use of parentheses, and a search history. Of those, 15 could not be included in this research, since they had not searched all databases we investigated here. At Erasmus MC, search strategies for systematic reviews are often designed via a librarian-mediated search service. We are aware that the Cochrane Handbook [7] recommends more than only these databases, but further recommendations focus on regional and specialized databases. Library users and staff use WorldCat Discovery to search the WorldCat database of electronic, digital and physical resources; to identify materials they need and to find out where they are available. Halladay CW, Trikalinos TA, Schmid IT, Schmid CH, Dahabreh IJ. 1 0 obj ; ; Cochrane CENTRAL is absent from the table, as for the five reviews limited to randomized trials, it did not add any unique included references. For this study, we searched to achieve as high a recall as possible, though our search strategies, like any other search strategy, still missed some relevant references because relevant terms had not been used in the search. 'VI/:NAf] N1b v4Fl8KTs cinQ An official website of the United States government. Nevertheless others have concluded that a single database is not sufficient to retrieve all references for systematic reviews [18, 19]. EMBASE versus MEDLINE for family medicine searches: can MEDLINE searches find the forest or a tree? statement and 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. 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. 2015;68:61726. FOIA Comparison of CINAHL, EMBASE, and MEDLIN . Medicine, Dentistry, Nursing & Allied Health.

It covers more than 50 nursing specialties and includes quick lessons, evidence-based care sheets, CEU modules and research instruments. 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 SMART Imagebase is a unique, educational resource for students, educators, library patrons, and professionals in healthcare and news media. This Spanish language database contains full text for 130 peer-reviewed medical journals in native Spanish. l1FcqL@Bk>>T A multi-disciplinary database, with more than 6,100 full-text periodicals, including more than 5,100 peer-reviewed journals. As our research is performed on systematic reviews, the main performance measure is recall. Note: With this limiter you will need to evaluate your results to determine what type of evidence each article contains. This number however is not an answer to the question of a researcher performing a systematic review, regarding which databases should be searched. PubMed Consequently . Optimal database combinations for literature searches in systematic reviews: a prospective exploratory study, https://doi.org/10.1186/s13643-017-0644-y, http://creativecommons.org/licenses/by/4.0/, http://creativecommons.org/publicdomain/zero/1.0/. 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. 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. 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. Springer Nature. The database itself is unfiltered, but includes many filtered items like systematic reviews. BMC Med Res Methodol. The three databases were searched for citations on topics selected by three nurse researchers and the results were compared. <> 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).

Systematic Reviews Films Media Group is the leading source of high-quality video and multimedia for academic, vocational and life-skills content. Ross-White A, Godfrey C. Is there an optimum number needed to retrieve to justify inclusion of a database in a systematic review search? Sixteen percent of the included references (291 articles) were only found in a single database; Embase produced the most unique references (n=132). 2. It therefore finds articles in which the topic of research is not mentioned in title, abstract, or thesaurus terms, but where the concepts are only discussed in the full text.

Article These values were calculated both for all reviews combined and per individual review. In short, the method consists of an efficient way to combine thesaurus terms and title/abstract terms into a single line search strategy. Using similar calculations, also shown in Table5, we estimated the probability that 100% of relevant references were retrieved is 23%. LearningExpress Library features nearly 1,000 online tutorials, practice tests, and eBooks to help patrons of all ages. A systematic approach to searching: how to perform high quality literature searches more efficiently. Disadvantages of using CINAHL There really aren't any, except that it's just a single database, and you might miss material that is available elsewhere. Beckles Z, Glover S, Ashe J, Stockton S, Boynton J, Lai R, Alderson P. Searching CINAHL did not add value to clinical questions posed in NICE guidelines. WB drafted the first manuscript, which was revised critically by the other authors. https://doi.org/10.1186/s13643-017-0644-y, DOI: https://doi.org/10.1186/s13643-017-0644-y. 2018. 2006 Jul;59(7):710-4. doi: 10.1016/j.jclinepi.2005.09.013. Once optimal recall is achieved, macros are used to translate the search syntaxes between databases, though manual adaptation of the thesaurus terms is still necessary. Since these studies have a long-term component, they promote abetter quality of evidence than a shorter study. Would you like email updates of new search results? Embase retrieved the most unique included references, followed by MEDLINE, Web of Science, and Google Scholar. The .gov means its official. MeSH 2005 Jan 8;5:2. doi: 10.1186/1471-2288-5-2. Searching multiple databases for systematic reviews: added value or diminishing returns? A researcher wants to be able to estimate the chances that his or her current project will miss a relevant reference. We estimate that 60% of published systematic reviews do not retrieve 95% of all available relevant references as many fail to search important databases.

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). andy gibb last interview. Halladay et al. Syst Rev. Improvement of precision was calculated as the ratio between the original precision from the searches in all databases and the precision for each database and combination. Handwashing OR "Hand Washing" OR "Hand Rubs" OR "Hand Disinfection". For all but one domain, the traditional combination of Embase, MEDLINE, and Cochrane CENTRAL did not retrieve enough included references. 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. While previous studies determined the coverage of databases, we analyzed the actual retrieval from the original searches for systematic reviews. 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. 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. Some concluded that searching only one database can be sufficient as searching other databases has no effect on the outcome [16, 17]. When searching for a systematic review, recall is the most important aspect, as the researcher does not want to miss any relevant references. Cited by lists all citing articles based on Crossref citations.Articles with the Crossref icon will open in a new tab. 2011. A total of 292 (17%) references were found by only one database.

Journal coverage, which spans from the 1800s to present, includes international material selected from around 2,400 periodicals in dozens of languages. It is laborious for searchers to translate a search strategy into multiple interfaces and search syntaxes, as field codes and proximity operators differ between interfaces. 2017. doi:10.1002/jrsm.1279. Conclusion If an included reference was not found in the EndNote file, we presumed the authors used an alternative method of identifying the reference (e.g., examining cited references, contacting prominent authors, or searching gray literature), and we did not include it in our analysis. 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.

Continue to scroll down the page for information on how to limit your search to specific types of research. In Excel, we calculated the performance of each individual database and various combinations. "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.

Registered in England & Wales No. Unique references were included articles that had been found by only one database search. Of the individual databases, Embase had the highest overall recall (85.9%). Article Bull Med Libr Assoc. 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]. who wins student body president riverdale. The information specialists of Erasmus MC developed an efficient method that helps them perform searches in many databases in a much shorter time than other methods. Wright K, Golder S, Lewis-Light K. What value is the CINAHL database when searching for systematic reviews of qualitative studies? 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. 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. Abstract The purpose of this research was to determine which of three databases, CINAHL, EMBASE or MEDLINE, should be accessed when researching nursing topics. These could be retrieved by searching PubMed with the subset as supplied by publisher. 5 Howick Place | London | SW1P 1WG. 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. This shows that many database searches missed relevant references. 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. and transmitted securely. Our experience in this study shows that additional efforts, such as hand searching, reference checking, and contacting key players, should be made to retrieve extra possible includes. For a search related to nursing, . 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. Comparing the coverage, recall, and precision of searches for 120 systematic reviews in Embase, MEDLINE, and Google Scholar: a prospective study. Review projects at Erasmus MC cover a wide range of medical topics, from therapeutic effectiveness and diagnostic accuracy to ethics and public health. endobj 2014;67:11929.

Librarian co-authors correlated with higher quality reported search strategies in general internal medicine systematic reviews. 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. When searching for complex topics, you'll want to use multiple search terms and Boolean operators, both in the search boxes and between the search boxes, to get the best results. Because this is a novel finding, we cannot conclude whether it is due to our dataset or to a generalizable principle. In that case, Google Scholar might add value by searching the full text of articles. There are disadvantages to using multiple databases. Embase and MEDLINE combined with either Google Scholar or Web of Science scored similarly well on overall recall (95.9%). 2023 BioMed Central Ltd unless otherwise stated. Comparing International Pharmaceutical Abstracts and MEDLINE. 4 and 5. Some reviewers might accept a potential loss of 5% of relevant references; others would want to pursue 100% recall, no matter what cost. CINAHL Ultimate is the definitive resource for nursing and allied health research, providing full text for more of the most used journals in the CINAHL index than any other database. Preston L, Carroll C, Gardois P, Paisley S, Kaltenthaler E. Syst Rev. 2011;91:1907. 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. WB and ML analyzed the data. For the search of nursing care literature on a medical condition, it . 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 . Once validated and certified for inclusion, these OA journals are treated with high-quality subject indexing and sophisticated, precise/accurate full-text linking. 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). In the case of a clinical question, precision is most important, as a practicing clinician does not have a lot of time to read through many articles in a clinical setting. Cookies policy. Over a third of the reviews were therapeutic, while slightly under a quarter answered an etiological question. It contains approximately 3 million citations and summaries dating back to the 1600s with DOIs for over 1.4 million records.
