A total of 292 (17%) references were found by only one database. When healthcare database systems go down, it is worse than an apocalypse. 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). Google Scholar. 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. 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. CINAHL provided the majority of relevant articles for the second search, on computers and privacy, but inclusion of MEDLINE and EMBASE enhanced retrieval somewhat. j 'o J Med Libr Assoc. In addition to journal articles, CINAHL includes books, book chapters, dissertations, and computer programs. 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. For the individual databases and combinations that were used in those reviews, we multiplied the frequency of occurrence in that set of 200 with the probability that the database or combination would lead to an acceptable recall (which we defined at 95%) that we had measured in our own data. Until 2016, the most complete MEDLINE selection in Ovid still lacked the electronic publications that were already available in PubMed. Once validated and certified for inclusion, these OA journals are treated with high-quality subject indexing and sophisticated, precise/accurate full-text linking. Bramer WM, Giustini D, Kramer BM, Anderson PF. Since May 2013, the first author prospectively recorded results from systematic review searches that he performed at his institution. Article [10] and van Enst et al. Thedatabase itself is unfiltered, but includes many filtered items like systematic reviews. However, for one review of this domain, the recall was 82%. We find that Embase is critical for acceptable recall in a review and should always be searched for medically oriented systematic reviews. 3 0 obj 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. 0_!g3SR}W/galG/g)Wz37;467WfW_E\wf_Q"#H3)j\]'gr[ ~dFq @Xj7yfC pOYAnaKruN" VI$wkD F\+ Fd7[)g `xBI@Oj FOIA Subject-specific databases such as CINAHL, PsycINFO, and SportDiscus only retrieved additional included references when the topic of the review was directly related to their special content, respectively nursing, psychiatry, and sports medicine. 2015;4:104. Lemeshow AR, Blum RE, Berlin JA, Stoto MA, Colditz GA. Searching one or two databases was insufficient for meta-analysis of observational studies. The site is secure. 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. Terms and Conditions, 2016;5:39. To compare our practice of database usage in systematic reviews against current practice as evidenced in the literature, we analyzed a set of 200 recent systematic reviews from PubMed. That is with the generous assumption that the searches in those databases had been designed sensitively enough. An overview of the broad topical categories covered in these reviews is given in Table2. There are disadvantages to using multiple databases. Where should the pharmacy researcher look first? Depending on the goal of the search, different measures may be optimized. Article 2015;68:107684. Nursing & Allied Health SourceTM provides users with reliable healthcare information covering nursing, allied health, alternative and complementary medicine. 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.

Embase and MEDLINE combined with either Google Scholar or Web of Science scored similarly well on overall recall (95.9%). Health Inf Libr J. In this case, the number of hits from Google Scholar was limited to 100. Note: You can use OR to link together your synonyms, or related words, in a search box, allowing the database to search more broadly. This site needs JavaScript to work properly. For reviews where RCTs are the desired study design, Cochrane CENTRAL may be similarly useful. Of the combinations of two databases, Embase and MEDLINE had the best results (92.8%). 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. We selected the domain from a pre-defined set of broad domains, including therapy, etiology, epidemiology, diagnosis, management, and prognosis. Quick Answer: What are Boolean operators? In Excel, we calculated the performance of each individual database and various combinations. 2 - CRzB:x{m9*eZvs@~&AWSiwY5a%Ofn(ehsVvu-O#Y+(t &c-SvTtFg *@WsWTy._,i@R(ay>EK4J=z}8S6(Cw viV%Q%bs-&{ CINAHL Complete contains full text for many of the most used journals found in the CINAHL index. 2014;67:11929.

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. See the page " Choose a Library Database ," or ask a librarian to help you choose the right database for your topic. 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. MEDLINE did find unique references that had not been found in Embase, although our searches in Embase included all MEDLINE records. This limiter box allows you to select specific article types. Recommended articles lists articles that we recommend and is powered by our AI driven recommendation engine. 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. This shows that many database searches missed relevant references. A nursing qualitative systematic review required MEDLINE and CINAHL for study identification. PubMed Central 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. Performance of a search can be expressed in different ways. >/- 8CqD 0:J AT~Xr Bx:.}U_y>gEdUug1tXA ed! J Clin Epidemiol. 2005 Jan;58(1):20-5. doi: 10.1016/j.jclinepi.2004.06.001. Ross-White A, Godfrey C. Is there an optimum number needed to retrieve to justify inclusion of a database in a systematic review search? For all but one domain, the traditional combination of Embase, MEDLINE, and Cochrane CENTRAL did not retrieve enough included references. Most articles on this topic draw their conclusions based on the coverage of databases [14]. Complement Ther Med. Unable to load your collection due to an error, Unable to load your delegates due to an error. On this page you will learn how to limit your results in CINAHL to: What is lost when searching only one literature database for articles relevant to injury prevention and safety promotion? Google Scholar. How do I view content? Google Scholar. CINAHL provided the majority of relevant articles for the second search, on computers and privacy, but inclusion of MEDLINE and EMBASE enhanced retrieval somewhat. Using similar calculations, also shown in Table5, we estimated the probability that 100% of relevant references were retrieved is 23%. Comparing International Pharmaceutical Abstracts and MEDLINE. 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. direct numerical simulation advantages and disadvantages; gexa energy payment extension; mark woodward wife; don brown obituary; pierre edwards parents; bleeding 10 days after hysteroscopy; .

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. 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. Nevertheless others have concluded that a single database is not sufficient to retrieve all references for systematic reviews [18, 19]. At Erasmus MC, search strategies for systematic reviews are often designed via a librarian-mediated search service.
