Article Are MEDLINE searches sufficient for systematic reviews and meta-analyses of the diagnostic accuracy of depression screening tools? The search on substance abuse in pregnancy, not restricted to nursing literature, retrieved better results when searching both MEDLINE and EMBASE. 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. They are usually one of the easiest study types to find in any nursing or medical database.

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. PubMed 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. Articles that are indexed with a set of identified thesaurus terms, but do not contain the current search terms in title or abstract, are screened to discover potential new terms. [17] found the added value of other databases only for newer, non-indexed references. When searching for a systematic review, recall is the most important aspect, as the researcher does not want to miss any relevant references. WB designed the searches used in this study and gathered the data. For reviews in our study that included RCTs only, indeed, this recommendation was sufficient for four (80%) of the reviews. T4: ieJ{rL;(N2:vIW(r]/[XupYo%$7^Qfo+hwy b "\*jn7N gx+]Bm+s[j9VPg/vw|u>$/a}:i)&b2#4+'{3O$=n#laK5qn9` 0*^0*I6DlBy 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. Most reviews did not limit to certain study designs, 9% limited to RCTs only, and another 9% limited to other study types. 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%. 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. 4 0 obj 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. "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.

Note: You can use OR to link together your synonyms, or related words, in a search box, allowing the database to search more broadly. Improvement of precision was calculated as the ratio between the original precision from the searches in all databases and the precision for each database and combination. However, when looking at individual reviews, the probability of missing more than 5% of included references found through database searching is 33% when Google Scholar is used together with Embase and MEDLINE and 30% for the Web of Science, Embase, and MEDLINE combination. There are disadvantages to using multiple databases. Syst Rev. Before For example, around a third of the reviews (37%) relied on the combination of MEDLINE and Embase. kON0=ArP35x`*[r(DYVBa9BJ2w\LueOJ=i.dR;mmP/P 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.

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. One hundred and fifty-nine journals are uniquely indexed in BNI compared with the basic version of CINAHL. A pragmatic evaluation of a new method for librarian-mediated literature searches for systematic reviews. Systematic reviews of epidemiology in diabetes: finding the evidence. In Excel, we calculated the performance of each individual database and various combinations. 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. 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%. vD@3h0MusH%|$e5Cl|Pl aWEEv~3v:hq`M 1LYi"eo*mZTmiMBV(']YJYa:{Xk4S9Tj-MLNAN}V%!U]h*us(5i:8}takdd-~^3I+LR0mkb4Kb3tTl! author reply e140.
