Res Synth Methods. Of the combinations of two databases, Embase and MEDLINE had the best results (92.8%). For all individual databases or combinations of the four important databases from our research (MEDLINE, Embase, Web of Science, and Google Scholar), we multiplied the frequency of occurrence of that combination in the random set, with the probability we found in our research that this combination would lead to an acceptable recall of 95%.

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. New candidate terms are added to the basic search and evaluated. Of all reviews in which we searched CINAHL and PsycINFO, respectively, for 6 and 9% of the reviews, unique references were found. Published reviews were included if the search strategies and results had been documented at the time of the last update and if, at minimum, the databases Embase, MEDLINE, Cochrane CENTRAL, Web of Science, and Google Scholar had been used in 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. For 55 reviews, we determined the domain. For all but one domain, the traditional combination of Embase, MEDLINE, and Cochrane CENTRAL did not retrieve enough included references. Many articles written on this topic have calculated overall recall of several reviews, instead of the effects on all individual reviews. 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. WB, JK, and OF designed the study.

Transcript. 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. We find that Embase is critical for acceptable recall in a review and should always be searched for medically oriented systematic reviews. Over a third of the reviews were therapeutic, while slightly under a quarter answered an etiological question. Our study shows that, to reach maximum recall, searches in systematic reviews ought to include a combination of databases.

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. Objective: To review the literature on the benefits and disadvantages of clinical and medical audit, and to assess the main facilitators and barriers to conducting the audit process. Sixteen percent of the included references (291 articles) were only found in a single database; Embase produced the most unique references (n=132).
