Abstract
Background: The Cochrane EMBASE project aims to identify randomized and quasi-randomized trials (RCTs/q-RCTs) using highly sensitive, validated search strategies developed by information specialists that are run in EMBASE. The results are screened for eligibility and inclusion in CENTRAL by volunteers using a crowdsourcing model (http://www.cochranelibrary.com/help/central-creation-details.html). One aim of this centralized search effort is to improve Cochrane Review Group’s Trials Search Co-ordinators’ (TSCs) efficiency by reducing duplication of effort in identifying studies in EMBASE for their registers and for CENTRAL.
Objectives: To determine whether the Cochrane ENT Group searches in EMBASE, designed to populate their register and CENTRAL, identify any unique RCTs/q-RCTs not found by the centralised EMBASE search.
Methods: The search strategies used are published in the Cochrane ENT module of the Cochrane Library (http://ow.ly/KtDMN). We will run these searches from May 2014 to May 2015 in Ovid EMBASE. We expect to retrieve approximately 3500 references. We will also run the ENT register searches in PubMed and CENTRAL, and upload results to the ENT segment of the Cochrane Register of Studies (CRS) first. We will then upload the records from EMBASE into CRS. We will use the CRS deduplication tool to exclude records already identified as relevant, or already excluded as ineligible. We will then screen the remaining references to identify any RCTs/q-RCTs in ENT that have not been identified through the centralised EMBASE project, the centralised PubMed search or the ENT Group’s search of PubMed.
Results: We will present the results of the searches, and the deduplication and screening of the records identified. If any additional trials are identified, we will inform the EMBASE project team.
Conclusions: We will seek to draw conclusions on whether or not it is efficient for the Cochrane ENT TSC to continue to search EMBASE separately, how these data might inform the wider TSC community and future centralised searching projects and how any anticipated efficiency savings might impact on making skilled resources available for other Cochrane projects.
