Objectives: Recently we developed a method with which systematic review searches are created ten times faster than traditional. In retrospective analysis, reviews created with this method retrieved significantly more relevant references than other librarian-mediated reviews. Now a group of experienced information specialists compares the method prospectively with traditional methods for multiple reviews. Does it reduce search time without missing relevant references?
Methods: After receiving a request for a librarian-mediated search for a systematic review, a participating information specialist clearly documents the topic and sends this to two other information specialists. One of the three searchers uses the new method. All three searchers try to find as many relevant references as possible. All search results are then combined, deduplicated and presented to the researchers to be screened for relevance.
The search time is registered. Number and overlap of terms in the searches and references retrieved by the searches are determined. After the review is finished, an independent information specialist compares the recall (%retrieved) and precision (%relevant) of the three search strategies for ultimately included references.
Is the new method faster than the other, traditional, methods? Did it miss important references the other searches found? Did it find relevant references the other methods missed?

Biomedical Information Specialist
Rotterdam, Zuid-Holland, Netherlands
Wichor Bramer has been working as biomedical information specialist at the Medical Library of Erasmus MC since 2009. His main tasks are to create exhaustive searches for systematic reviews, and to develop and conduct workshops for PhDs on systematic searching in various databases.
He has developed a method that helps him create exhaustive and high quality searches in a much shorter time than usual, and a method for fast but accurate deduplication of obtained references. This allows him to design, perform, execute, and import into reference software and deduplicate the results of the searches for over 250 systematic reviews on a yearly basis. He is currently pursuing a PhD, specializing in librarian-mediated searches for systematic reviews.
