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. A secondary aim is to investigate the current practice of databases searched for published reviews. Table3 displays the number of unique results retrieved for each single database. Additionally, search strategies are limited to a maximum of 256 characters, which means that creating a thorough search strategy can be laborious. We've already shown how to use this limiter for systematic reviews and case studies; other useful publication types for evidence-based practice include Clinical Trial and Meta Analysis. We selected the domain from a pre-defined set of broad domains, including therapy, etiology, epidemiology, diagnosis, management, and prognosis. This filter can be usedfind articles that are clinically-sound. PubMed Central PubMed 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. 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. A nursing qualitative systematic review required MEDLINE and CINAHL for study identification. This limiter box allows you to select specific article types. Fifty one of the 81 titles . endobj 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. 2005 Jan;58(1):20-5. doi: 10.1016/j.jclinepi.2004.06.001. A comparative study of clinical end-user and librarian searches. CAS 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. J Kerman Univ Med Sci. For reviews where RCTs are the desired study design, Cochrane CENTRAL may be similarly useful. Wilkins T, Gillies RA, Davies K. EMBASE versus MEDLINE for family medicine searches: can MEDLINE searches find the forest or a tree? Technical Problems Every computer system will have a breakdown. For each published systematic review, we extracted the references of the included studies. We did not investigate whether the loss of certain references had resulted in changes to the conclusion of the reviews. Part of Some reviewers might accept a potential loss of 5% of relevant references; others would want to pursue 100% recall, no matter what cost. In our analyses, we combined the results from MEDLINE in Ovid and PubMed (the subset as supplied by publisher) into one database labeled MEDLINE. Rethlefsen ML, Farrell AM, Osterhaus Trzasko LC, Brigham TJ. We are aware that the Cochrane Handbook [7] recommends more than only these databases, but further recommendations focus on regional and specialized databases. What is considered acceptable recall for systematic review searches is open for debate and can differ between individuals and groups. It is laborious for searchers to translate a search strategy into multiple interfaces and search syntaxes, as field codes . Based on our findings, this combination achieves acceptable recall about half the time (47%). 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. On 5 January 2017, we searched PubMed for articles with the phrase systematic review in the title. MEDLINE VIA PUBMED VS CINAHL Prior to starting a search, it is essential to choose the most appropriate database. Optimal database combinations for literature searches in systematic reviews: a prospective exploratory study. f~C>j)Kx8t>qi0@fWT. New candidate terms are added to the basic search and evaluated. The database combinations with the highest recall did not reduce the total number of results by large margins. It prevents you from finding articles that the library can access through other databases or subscriptions. 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. 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. Unique references were included articles that had been found by only one database search. Of the 11 references included in this review, one was found only in Google Scholar and one only in Web of Science. Most reviews did not limit to certain study designs, 9% limited to RCTs only, and another 9% limited to other study types. Embase retrieved the most unique included references, followed by MEDLINE, Web of Science, and Google Scholar. Springer Nature. 11 reviews, where we were able to recheck all the databases used by the original review authors, had included a study that was uniquely identified from the CINAHL database. official website and that any information you provide is encrypted The purpose of this research was to determine which of three databases, CINAHL, EMBASE or MEDLINE, should be accessed when researching nursing topics. A total of 292 (17%) references were found by only one database. The calculation is shown in Table5. 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. WB designed the searches used in this study and gathered the data. 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. 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). PubMed Central Using both Web of Science and Google Scholar in addition to MEDLINE and Embase increased the overall recall to 98.3%. Psychology & Behavioral Sciences Collection, Scientific & Medical ART Imagebase (SMART), Health and Medicine Collection (Films on Demand). Bull Med Libr Assoc. The Cochrane Handbook, for example, recommends the use of at least MEDLINE and Cochrane Central and, when available, Embase for identifying reports of randomized controlled trials [7]. 8600 Rockville Pike 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%.

This search is then optimized. The purpose of this research was to determine which of three databases, CINAHL, EMBASE or MEDLINE, should be accessed when researching nursing topics. Of those, 15 could not be included in this research, since they had not searched all databases we investigated here. Almost all reviews (97%) reported a search in MEDLINE. 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. Most articles on this topic draw their conclusions based on the coverage of databases [14]. Thedatabase itself is unfiltered, but includes many filtered items like systematic reviews. Over a third of the reviews were therapeutic, while slightly under a quarter answered an etiological question. 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 . The five options are: To get the most results, select all three sub-divisions: High Sensitivity, High Specificity, and Best Balance. Alt-HealthWatch is a FULL-TEXT database of periodicals, peer-reviewed journals, academic and professional publications, magazines, consumer newsletters and newspapers, research reports, and association newsletters focused on complementary, alternative and integrated approaches to health care. 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. 2005 Jan 8;5:2. doi: 10.1186/1471-2288-5-2. By using this website, you agree to our PubMed The major strength of our paper is that it is the first large-scale study we know of to assess database performance for systematic reviews using prospectively collected data. Since these studies have a long-term component, they promote abetter quality of evidence than a shorter study. A comparison of the performance of seven key bibliographic databases in identifying all relevant systematic reviews of interventions for hypertension. [17] found the added value of other databases only for newer, non-indexed references. Rathbone J, Carter M, Hoffmann T, Glasziou P. Syst Rev. Whether Embase and Web of Science can be replaced by Scopus remains uncertain. The datasets generated and/or analyzed during the current study are available from the corresponding author on a reasonable request. 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. From: Complementary Therapies for Physical Therapy, 2008 View all Topics Add to Mendeley 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. This can be offset, as noted above, by going to the EBSCOhost (Health) package of databases. 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. Comput Biomed Res. Our conclusion that Web of Science and Google Scholar are needed for completeness has not been shared by previous research. Lastly, we checked whether the reviews described limiting their included references to a particular study design. 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. Bramer WM, de Jonge GB, Rethlefsen ML, Mast F, Kleijnen J. Unique results from specialized databases that closely match systematic review topics, such as PsycINFO for reviews in the fields of behavioral sciences and mental health or CINAHL for reviews on the topics of nursing or allied health, indicate that specialized databases should be used additionally when appropriate. Sixteen percent of the included references (291 articles) were only found in a single database; Embase produced the most unique references (n=132). 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. Complexity The provision of the functionality we expect of a good DBMS makes the DBMS an extremely complex piece of software. One hundred and fifty-nine journals are uniquely indexed in BNI compared with the basic version of CINAHL. As our research is performed on systematic reviews, the main performance measure is recall. In 72% of studied systematic reviews, the combination of Embase, MEDLINE, Web of Science, and Google Scholar retrieved all included references. Ross-White A, Godfrey C. Is there an optimum number needed to retrieve to justify inclusion of a database in a systematic review search? 9v[-[TkBaly.Ja%"uu'Nd&nNSevS}VXcS63#qN From the published journal article, we extracted the list of final included references. @mR]L#-wbtR5Q Embase and MEDLINE combined with either Google Scholar or Web of Science scored similarly well on overall recall (95.9%). If the research question is more interdisciplinary, a broader science database such as Web of Science is likely to add value. 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. A researcher wants to be able to estimate the chances that his or her current project will miss a relevant reference. 2016;87:713. In both these reviews, the topic was highly related to the topic of the database. For all but one domain, the traditional combination of Embase, MEDLINE, and Cochrane CENTRAL did not retrieve enough included references. 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. This database also offers indexing and abstracts for more than 10,100 journals and a total of 10,600 publications including monographs, reports, conference proceedings, etc. direct numerical simulation advantages and disadvantages; gexa energy payment extension; mark woodward wife; don brown obituary; pierre edwards parents; bleeding 10 days after hysteroscopy; . 2016;16:113.

Literature search parameters marginally improved the pooled estimate accuracy for ultrasound in detecting deep venous thrombosis. author reply e140. This site needs JavaScript to work properly. Disadvantages of Databases 1. 2014;67:11929. 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. BMC Med Res Methodol. PubMed Beyer FR, Wright K. Can we prioritise which databases to search? For a sample of 200 recently published systematic reviews, we calculated how many had used enough databases to ensure 95% recall. Terms and Conditions, Privacy Google Scholar. 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. Subirana M, Sol I, Garcia JM, Gich I, Urrtia G. J Clin Epidemiol. Fifty-one of these journals are UK publications. vD@3h0MusH%|$e5Cl|Pl aWEEv~3v:hq`M 1LYi"eo*mZTmiMBV(']YJYa:{Xk4S9Tj-MLNAN}V%!U]h*us(5i:8}takdd-~^3I+LR0mkb4Kb3tTl! 2013 Jan 9;13:7. doi: 10.1186/1472-6947-13-7. 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. Rice DB, Kloda LA, Levis B, Qi B, Kingsland E, Thombs BD. 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. 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. 3099067 2. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). This number however is not an answer to the question of a researcher performing a systematic review, regarding which databases should be searched. These could be retrieved by searching PubMed with the subset as supplied by publisher. FOIA Google Scholar. National Library of Medicine 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.
