3 for the legend of the plots in Figs. Using similar calculations, also shown in Table5, we estimated the probability that 100% of relevant references were retrieved is 23%. 4 0 obj Although Embase covers MEDLINE, it apparently does not index every article from MEDLINE. endobj These values were calculated both for all reviews combined and per individual review. 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. Gale Health and Wellness offers 24/7 access to full-text medical journals, magazines, reference works, multimedia, and much more. Google Scholar, Zheng MH, Zhang X, Ye Q, Chen YP. Google Scholar. While previous studies determined the coverage of databases, we analyzed the actual retrieval from the original searches for systematic reviews. Halladay CW, Trikalinos TA, Schmid IT, Schmid CH, Dahabreh IJ. The references to these reviews can be found in Additional file 1. For reviews in our study that included RCTs only, indeed, this recommendation was sufficient for four (80%) of the reviews. See Table1 for definitions of these measures. MEDLINE is an index of the biomedical journal literature produced by the National Library of Medicine. Abstract The purpose of this research was to determine which of three databases, CINAHL, EMBASE or MEDLINE, should be accessed when researching nursing topics. 5 Howick Place | London | SW1P 1WG. To learn more about Boolean operators, please see this Quick Answer: Here is an example of how to put together a complex search in CINAHL: Note: If you have not already logged in to the Library databases, you will be prompted to log in with your myWalden Portal user name and password. However, for one review of this domain, the recall was 82%. disadvantages of cinahl database. Registered in England & Wales No. Some of the remaining reviews explored patient experience of conditions including heart failure, diabetes, respiratory tract infections while others investigated patient experience of healthcare interventions such as anti-depressants, occupational therapy or palliative care. 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. In both these reviews, the topic was highly related to the topic of the database. When the overall number of hits was low, we additionally searched Scopus, and when appropriate for the topic, we included CINAHL (EBSCOhost), PsycINFO (Ovid), and SportDiscus (EBSCOhost) in our search. &Jl1/>nw\CCX=prz Dcr8UBW3L`Du8*r (+P/:SXQB^ 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. 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. Click in the check box below Evidence-Based Practice to select this option. Google Scholar. 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. 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. PubMed 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 contrast, searching too many databases has clear disadvantages, as the search strategy must be translated to fit different databases using different interfaces and search syntaxes, and the. :p#("-!r>5"@5Ip^P|~1zsqE- @QK 2016 Feb 9;5:27. doi: 10.1186/s13643-016-0197-5. Ross-White A, Godfrey C. Is there an optimum number needed to retrieve to justify inclusion of a database in a systematic review search? Bramer WM, Giustini D, Kramer BMR. The interventions were mostly from the chemicals and drugs category, or surgical procedures. Explain how resolving your EBP Project issue will improve . who wins student body president riverdale. Lemeshow AR, Blum RE, Berlin JA, Stoto MA, Colditz GA. Searching one or two databases was insufficient for meta-analysis of observational studies. An overview of the broad topical categories covered in these reviews is given in Table2. Posted on 16 December 2021 - 7:39 pm by . Some reviewers might accept a potential loss of 5% of relevant references; others would want to pursue 100% recall, no matter what cost. Eighty-one journals are uniquely indexed in BNI compared with all versions of CINAHL. Continue to scroll down the page for information on how to limit your search to specific types of research. "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. Bramer WM, de Jonge GB, Rethlefsen ML, Mast F, Kleijnen J. 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. For reviews where RCTs are the desired study design, Cochrane CENTRAL may be similarly useful. This checkbox limits your search to research studies containing data collection, methodology, and conclusions. We analyzed whether the added value of Web of Science and Google Scholar was dependent of the domain of the review. In Excel, we calculated the performance of each individual database and various combinations. 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. A comparison of the performance of seven key bibliographic databases in identifying all relevant systematic reviews of interventions for hypertension. 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 assessed the frequency at which databases and combinations would achieve varying levels of recall (i.e., 95%). We estimate that 60% of published systematic reviews do not retrieve 95% of all available relevant references as many fail to search important databases. Our conclusion that Web of Science and Google Scholar are needed for completeness has not been shared by previous research. 2005 Jan 8;5:2. doi: 10.1186/1471-2288-5-2. Of course, the loss of a minor non-randomized included study that follows the systematic reviews conclusions would not be as problematic as losing a major included randomized controlled trial with contradictory results. 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. 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. 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. 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. Are MEDLINE searches sufficient for systematic reviews and meta-analyses of the diagnostic accuracy of depression screening tools? Conclusion Size A comparative study of clinical end-user and librarian searches. Bethesda, MD 20894, Web Policies References to the systematic reviews published by Erasmus MC authors that were included in the research. 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.

If the research question is more interdisciplinary, a broader science database such as Web of Science is likely to add value. The content is solely the responsibility of the authors and does not necessarily represent the official views of the National Institutes of Health. 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. Syst Rev 6, 245 (2017). How do I view content? Ahntastic Adventures in Silicon Valley The skills and experience of the searcher are one of the most important aspects in the effectiveness of systematic review search strategies [23,24,25]. Since May 2013, the first author prospectively recorded results from systematic review searches that he performed at his institution. CINAHL indexing terms and policies reflect a more general approach and the index term "diagnosis," when exploded (ie, when all subdivisions of the indexed term are retrieved), covers most aspects of nursing assessment, screening (people with no symptoms or indications of disease), and diagnosis (people with symptoms or conditions suggestive of We documented the department of the first author. 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. Syst Rev. Technical Problems Every computer system will have a breakdown. By closing this message, you are consenting to our use of cookies. Can Fam Physician. Based on these, we determined the percentage of reviews where that database combination had achieved 100% recall, more than 95%, more than 90%, and more than 80%. J Med Libr Assoc. 2018. Based on our findings, this combination achieves acceptable recall about half the time (47%). . The other authors declare no competing interests. Correspondence to 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. Bull Med Libr Assoc. Comparing the coverage, recall, and precision of searches for 120 systematic reviews in Embase, MEDLINE, and Google Scholar: a prospective study. 1 0 obj Rethlefsen ML, Farrell AM, Osterhaus Trzasko LC, Brigham TJ. Health Source: Nursing/Academic Editionalso features theLexi-PAL Drug Guide,which covers 1,300 generic drug patient education sheets with more than 4,700 brand names. In 12 reviews (52%), Scopus retrieved 100% of all included references retrieved by Embase or Web of Science. Moreover, in combinations where the number of results was greatly reduced, the recall of included references was lower. Embase and MEDLINE combined with either Google Scholar or Web of Science scored similarly well on overall recall (95.9%). <> Furthermore, it is time-consuming for reviewers who have to screen more, and likely irrelevant, titles and abstracts. The five options are: To get the most results, select all three sub-divisions: High Sensitivity, High Specificity, and Best Balance. 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. From a set of 200 recent SRs identified via PubMed, we analyzed the databases that had been searched. 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. The researchers that requested the search received a deduplicated EndNote file from which they selected the references relevant for inclusion in their systematic review. For each published systematic review, we extracted the references of the included studies. Once validated and certified for inclusion, these OA journals are treated with high-quality subject indexing and sophisticated, precise/accurate full-text linking. Disadvantages of Databases 1. Thirty-seven references were found in MEDLINE (Ovid) but were not available in Embase.com. However, the combination with Google Scholar had a higher precision and higher median recall, a higher minimum recall, and a higher proportion of reviews that retrieved all included references. Of the combinations of two databases, Embase and MEDLINE had the best results (92.8%). PubMed 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. 2016;87:713. Handwashing OR "Hand Washing" OR "Hand Rubs" OR "Hand Disinfection". We find that Embase is critical for acceptable recall in a review and should always be searched for medically oriented systematic reviews. Hold down the Ctrl key to select multiple options. A secondary aim is to investigate the current practice of databases searched for published reviews. 2014;67:11929. Res Synth Methods. A researcher wants to be able to estimate the chances that his or her current project will miss a relevant reference. Article 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. Our experience has shown us that it is also impacted by the ability of the searcher, the accuracy of indexing of the database, and the complexity of terminology in a particular field. >/- 8CqD 0:J AT~Xr Bx:.}U_y>gEdUug1tXA ed! For all but one domain, the traditional combination of Embase, MEDLINE, and Cochrane CENTRAL did not retrieve enough included references.

NOTE There are many limiters that we haven't covered. 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. Most of the previous studies did not include these two databases in their research. The sum of all these values is the total probability of acceptable recall in the random sample. 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].
