By using this website, you agree to our 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. PubMed was used to identify systematic reviews published using our search strategy results. At Erasmus MC, search strategies for systematic reviews are often designed via a librarian-mediated search service. It covers more than 50 nursing specialties and includes quick lessons, evidence-based care sheets, CEU modules and research instruments. These values were calculated both for all reviews combined and per individual review. 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? Health Inf Libr J. Handwashing OR "Hand Washing" OR "Hand Rubs" OR "Hand Disinfection". Of the combinations of two databases, Embase and MEDLINE had the best results (92.8%). PubMed The Cochrane Handbook recommends searching MEDLINE, Cochrane CENTRAL, and Embase for systematic reviews of RCTs. Because of this major limitation, the question of which databases are necessary to retrieve all relevant references for a systematic review remains unanswered. We recommend that, regardless of their topic, searches for biomedical systematic reviews should combine Embase, MEDLINE (including electronic publications ahead of print), Web of Science (Core Collection), and Google Scholar (the 200 first relevant references) at minimum. Subirana M, Sol I, Garcia JM, Gich I, Urrtia G. J Clin Epidemiol. Evid Based Libr Inf Pract. A recent paper tried to find an acceptable number needed to read for adding an additional database; sadly, however, no true conclusion could be drawn [20]. Our earlier research had resulted in 206 systematic reviews published between 2014 and July 2016, in which the first author was affiliated with Erasmus MC [21]. 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. Systematic Reviews 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. 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. 2014;30:1738. Lastly, we checked whether the reviews described limiting their included references to a particular study design. What is considered acceptable recall for systematic review searches is open for debate and can differ between individuals and groups. Select an option by finding it in the list and clicking on it (it will then be highlighted). Careers. Thirty-seven references were found in MEDLINE (Ovid) but were not available in Embase.com. See Table1 for definitions of these measures. 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. When searching for a systematic review, recall is the most important aspect, as the researcher does not want to miss any relevant references. how to send secure email attachments in gmail. 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 CINAHL Plus with Full Text database is an unfiltered database containing over 750 nursing and allied health related journals, and indexes another 5,000. A nursing qualitative systematic review required MEDLINE and CINAHL for study identification. Literature search parameters marginally improved the pooled estimate accuracy for ultrasound in detecting deep venous thrombosis. This database provides nearly 550 scholarly full text journals focusing on many medical disciplines. @mR]L#-wbtR5Q BNI is represented three times in the table because the number of unique titles per database depends on whether CINAHL, CINAHL Plus or CINAHL Complete is being compared. The three databases were searched for citations on topics selected by three nurse researchers and the results were compared. See Fig. 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. PubMed Central For all but one domain, the traditional combination of Embase, MEDLINE, and Cochrane CENTRAL did not retrieve enough included references. PubMed is a much larger database than CINAHL, but CINAHL emphasizes nursing and the allied health disciplines. The three databases were searched for citations on topics selected by three nurse researchers and the results were compared. Accessibility It offers job search and workplace skills improvement, skill building in reading, writing, math, and basic science, career certification and licensure exam prep, college and grad school entrance test prep, GED test prep, and more. 2019 Aug;21(4):853-878. doi: 10.1007/s10903-018-0816-4. J Clin Epidemiol. The SMART Imagebase is a unique, educational resource for students, educators, library patrons, and professionals in healthcare and news media. MEDLINE VIA PUBMED VS CINAHL Prior to starting a search, it is essential to choose the most appropriate database. For a sample of 200 recently published systematic reviews, we calculated how many had used enough databases to ensure 95% recall. Wright K, Golder S, Lewis-Light K. What value is the CINAHL database when searching for systematic reviews of qualitative studies? Note: You can use OR to link together your synonyms, or related words, in a search box, allowing the database to search more broadly. In this case, the number of hits from Google Scholar was limited to 100. WB and ML analyzed the data. 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 . 2005;93:7480. 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). J Clin Epidemiol. WB drafted the first manuscript, which was revised critically by the other authors. Lawrence DW. Technical Problems Every computer system will have a breakdown. volume6, Articlenumber:245 (2017) 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. In Excel, we calculated the performance of each individual database and various combinations. }UCby^4(-\SHU1B CPn(ULF{fUUog].[>~si|F] mykK+NGz While previous studies determined the coverage of databases, we analyzed the actual retrieval from the original searches for systematic reviews. Google Scholar, Zheng MH, Zhang X, Ye Q, Chen YP. ``6C~8 '* "r#=e ax A+ 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.

We did not investigate whether the loss of certain references had resulted in changes to the conclusion of the reviews. Sixteen percent of the included references (291 articles) were only found in a single database; Embase produced the most unique references (n=132). Res Synth Methods. 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 more. 2011. There is an overlap in the journals indexed by these two databases. andy gibb last interview.

The searcher in the case of all 58 systematic reviews is an experienced biomedical information specialist. 2015;68:61726. Bookshelf endobj 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. 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]. Therefore, we research the probability that single or various combinations of databases retrieve the most relevant references in a systematic review by studying actual retrieval in various databases. Our study shows that, to reach maximum recall, searches in systematic reviews ought to include a combination of databases. 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. On this page you will learn how to limit your results in CINAHL to: Imagine you are a patient with cancer and your doctor can't order your pain medication. BMC Med Res Methodol. 2016;16:161. van Enst WA, Scholten RJ, Whiting P, Zwinderman AH, Hooft L. Meta-epidemiologic analysis indicates that MEDLINE searches are sufficient for diagnostic test accuracy systematic 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. For example, around a third of the reviews (37%) relied on the combination of MEDLINE and Embase. Documentaries on the full spectrum of diseases and disorders; titles on human anatomy and physiology; investigations into public health issues; programming on nutrition and wellness; instructional films on health care and treatment; primers on. We selected the domain from a pre-defined set of broad domains, including therapy, etiology, epidemiology, diagnosis, management, and prognosis. In both these reviews, the topic was highly related to the topic of the database. J Psychosom Res. Comparing the coverage, recall, and precision of searches for 120 systematic reviews in Embase, MEDLINE, and Google Scholar: a prospective study. Of all reviews in which we searched CINAHL and PsycINFO, respectively, for 6 and 9% of the reviews, unique references were found. https://doi.org/10.1186/s13643-017-0644-y, DOI: https://doi.org/10.1186/s13643-017-0644-y. For example, in 48% of all systematic reviews, the combination of Embase and MEDLINE (with or without Cochrane CENTRAL; Cochrane CENTRAL did not add unique relevant references) reaches a recall of at least 95%. Are included references being missed because the review authors failed to search a certain database? The highest scoring database combination without Embase is a combination of MEDLINE, Web of Science, and Google Scholar, but that reaches satisfactory recall for only 39% of all investigated systematic reviews, while still requiring a paid subscription to Web of Science. 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. For a search related to nursing, . This study also highlights once more that searching databases alone is, nevertheless, not enough to retrieve all relevant references.
