Although Embase covers MEDLINE, it apparently does not index every article from MEDLINE. Disadvantages of Databases 1. 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.

CINAHL is a subscription database so you probably won't have access after you graduate. 2005 Jan;58(1):20-5. doi: 10.1016/j.jclinepi.2004.06.001. Using the results in this research, review teams can decide, based on their idea of acceptable recall and the desired probability which databases to include in their searches. 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. Beyer FR, Wright K. Can we prioritise which databases to search? The other authors declare no competing interests. In Excel, we calculated the performance of each individual database and various combinations. Article The database combinations with the highest recall did not reduce the total number of results by large margins. Syst Rev. 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. 2015 Jun 26;4:82. doi: 10.1186/s13643-015-0074-7. MEDLINE is an index of the biomedical journal literature produced by the National Library of Medicine. The topics of the reviews studied here may simply have fallen into those categories, though the diversity of the included reviews may point to a more universal applicability. If this resulted in extraneous results, the search was subsequently limited using a distinct part of the title or a second author name. j 'o 2013;30:4958. National Library of Medicine The other study from the Journal of Advanced Nursing is indexed in MEDLINE and Embase but was only retrieved because of the addition of KeyWords Plus in Web of Science. mOkV1#8 (uTb Scroll down the page below the search boxes to locate these filters or limiters. HR;QBYVCU-7;-7O?zIo =IBK OH)k11H?3xQao7~Z| Using similar calculations, also shown in Table5, we estimated the probability that 100% of relevant references were retrieved is 23%. For a search related to nursing, . Stroke. We are aware that the Cochrane Handbook [7] recommends more than only these databases, but further recommendations focus on regional and specialized databases. Select an option by finding it in the list and clicking on it (it will then be highlighted). For the search of nursing care literature on a medical condition, it . 4 and 5. Ahntastic Adventures in Silicon Valley 2005;58:86773. PubMed I;u?5Z=bL(lWh{d QrX". 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. Lorenzetti DL, Topfer L-A, Dennett L, Clement F. Value of databases other than MEDLINE for rapid health technology assessments. That is with the generous assumption that the searches in those databases had been designed sensitively enough. Fifty-one of these journals are UK publications. Of those, 15 could not be included in this research, since they had not searched all databases we investigated here. See Table1 for definitions of these measures. For four out of five systematic reviews that limited to randomized controlled trials (RCTs) only, the traditional combination retrieved 100% of all included references. 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%. California Privacy Statement, How do I view content? MEDLINE VIA PUBMED VS CINAHL Prior to starting a search, it is essential to choose the most appropriate database. Quick Answer: What are Boolean operators? J Kerman Univ Med Sci. Systematic review searchers should consider using these databases if they are available to them, and if their institution lacks availability, they should ask other institutes to cooperate on their systematic review searches. Are included references being missed because the review authors failed to search a certain database? 2004;12:22832. Wilkins T, Gillies RA, Davies K. EMBASE versus MEDLINE for family medicine searches: can MEDLINE searches find the forest or a tree? 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. Transcript. Correspondence to The three databases were searched for citations on topics selected by three nurse researchers and the results were compared. Depending on the goal of the search, different measures may be optimized. Cookies policy. Finding resources: MEDLINE. 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. 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. Some reviewers might accept a potential loss of 5% of relevant references; others would want to pursue 100% recall, no matter what cost. This is the world's largest full text psychology database offering full text coverage for nearly 400 journals. Designed for an audience ranging from novice test consumers to experienced professionals, the MMY series contains information essential for a complete evaluation of test products within such diverse areas as psychology, education, business, and leadership. Most reviews did not limit to certain study designs, 9% limited to RCTs only, and another 9% limited to other study types. 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. 2011;91:1907. 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. Nevertheless others have concluded that a single database is not sufficient to retrieve all references for systematic reviews [18, 19]. Federal government websites often end in .gov or .mil. Therefore, for this research, a total of 58 systematic reviews were analyzed. Provided by the Springer Nature SharedIt content-sharing initiative. Res Synth Methods. To ensure adequate performance in searches (i.e., recall, precision, and number needed to read), we find that literature searches for a systematic review should, at minimum, be performed in the combination of the following four databases: Embase, MEDLINE (including Epub ahead of print), Web of Science Core Collection, and Google Scholar. 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. 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 . Consequently . In the other 48%, the recall by Scopus was suboptimal, in one occasion as low as 38%. However, for one review of this domain, the recall was 82%. 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. Nursing & Allied Health SourceTM provides users with reliable healthcare information covering nursing, allied health, alternative and complementary medicine. In our analyses, we combined the results from MEDLINE in Ovid and PubMed (the subset as supplied by publisher) into one database labeled MEDLINE. 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. In short, the method consists of an efficient way to combine thesaurus terms and title/abstract terms into a single line search strategy. If the research question is more interdisciplinary, a broader science database such as Web of Science is likely to add value. Whether Embase and Web of Science can be replaced by Scopus remains uncertain. An official website of the United States government. 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. Bramer, W.M., Rethlefsen, M.L., Kleijnen, J. et al. J Med Libr Assoc. 2015;10:5068. This happens, particularly with lesser-used medications and treatments. 5 Howick Place | London | SW1P 1WG. 2019 Aug;21(4):853-878. doi: 10.1007/s10903-018-0816-4. 2017;33:21724. Of the five reviews that included only RCTs, four reached 100% recall if MEDLINE, Web of Science, and Google Scholar combined were complemented with Cochrane CENTRAL.

Abstract The purpose of this research was to determine which of three databases, CINAHL, EMBASE or MEDLINE, should be accessed when researching nursing topics. In general, we use the first 200 references as sorted in the relevance ranking of Google Scholar. Most articles on this topic draw their conclusions based on the coverage of databases [14]. Within systematic reviews, when searching for relevant references, it is advisable to use multiple databases. 2011. Many of the articles reporting on previous research concluded that one database was able to retrieve most included references. 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? J Clin Epidemiol. Almost all reviews (97%) reported a search in MEDLINE. 2005 Jan 8;5:2. doi: 10.1186/1471-2288-5-2. Searching only Embase produced an NNR of 57 on average, whereas, for the optimal combination of four databases, the NNR was 73. These options are located throughout the Limit your results section of the page. Complexity The provision of the functionality we expect of a good DBMS makes the DBMS an extremely complex piece of software. When the number of references from other databases was low, we expected the total number of potential relevant references to be low. Lemeshow AR, Blum RE, Berlin JA, Stoto MA, Colditz GA. Searching one or two databases was insufficient for meta-analysis of observational studies. 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. 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. However, Embase is only accessible via a paid subscription, which generally makes it challenging for review teams not affiliated with academic medical centers to access. 9v[-[TkBaly.Ja%"uu'Nd&nNSevS}VXcS63#qN 2 0 obj Journal coverage, which spans from the 1800s to present, includes international material selected from around 2,400 periodicals in dozens of languages. 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. Performance of a search can be expressed in different ways. A review of meta-analyses.

Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. 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]. Although we did not use these special topic databases in all of our reviews, given the low number of reviews where these databases added relevant references, and observing the special topics of those reviews, we suggest that these subject databases will only add value if the topic is related to the topic of the database. Nursing: Indexes & Databases. Subject-specific databases like PsycINFO only added unique references to a small percentage of systematic reviews when they had been used for the search. PubMed Conclusion For a sample of 200 recently published systematic reviews, we calculated how many had used enough databases to ensure 95% recall. Though we occasionally used the regional databases LILACS and SciELO in our reviews, they did not provide unique references in our study.

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. 2005;93:7480. "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. Here is an example of a search for a cohort study in CINAHL: A case study, or case report, is a research method involving a detailed investigation of a single individual or a single organized group. This search is then optimized. 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.

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. 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. Most of the selected UK nursing journals have earlier start and entry dates in CINAHL than BNI. Films Media Group is the leading source of high-quality video and multimedia for academic, vocational and life-skills content. We find that Embase is critical for acceptable recall in a review and should always be searched for medically oriented systematic reviews. Percentage of systematic reviewsof a certain domainfor which the combination Embase, MEDLINE and Cochrane CENTRAL reached a certain recall. Many articles written on this topic have calculated overall recall of several reviews, instead of the effects on all individual reviews. The sum of all these values is the total probability of acceptable recall in the random sample. They are usually one of the easiest study types to find in any nursing or medical database. A total of 58 published systematic reviews were included, totaling 1746 relevant references identified by our database searches, while 84 included references had been retrieved by other search methods. We determined the databases that contributed most to the reviews by the number of unique references retrieved by each database used in the reviews. 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. This implies that 17% of the reviews in the PubMed sample would have achieved an acceptable recall of 95%. 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 . Beginning in May 2013, the number of records retrieved from each search for each database was recorded at the moment of searching. It is therefore important to search MEDLINE including the Epub Ahead of Print, In-Process, and Other Non-Indexed Citations references. Also, while the Scopus and Web of Science assumptions we made might be true for coverage, they are likely very different when looking at recall, as Scopus does not allow the use of the full features of a thesaurus. Future research should continue to investigate recall of actual searches beyond coverage of databases and should consider focusing on the most optimal database combinations, not on single databases. We have not yet gathered enough data to be able to make a full comparison between Embase and Scopus. For the search of nursing care literature on a medical condition, it was helpful to search both CINAHL and MEDLINE.
