Covidence is web based software that simplifies the process of screening references and extracting data for systematic reviews.
St Vincent's Hospital Melbourne has an institutional licence for staff. Please contact us to request access.You will then be able to set up reviews and invite co-reviewers, including those from other organisations.
Review teams have at least two, and usually more reviewers. If you are working alone then you are not doing a systematic review and you don't need Covidence.
Library staff can teach you literature searching skills, and how to manage citations with Endnote. We have a limited capacity to co-author systematic reviews where we take responsibility for the search process and writing up the methodology.
Getting references involves a thorough search of multiple databases such as Medline, Embase, Emcare, CINAHL, PsycINFO and the Cochrane Library. Designing a good search strategy is key to this process, and forms the basis of a systematic review.
Export search results to Endnote before uploading them to Covidence. Staff of St Vincent's Hospital Melbourne can access Endnote onsite and library staff can provide installation software for offsite use. Individual and group tutorials on using Endnote are available on request. Please contact us for more information.
Remove duplicates in Endnote before uploading to Covidence, especially if you have a lot of records. Covidence will remove duplicates on import (and does it well), but these still need to be checked, and that can be cumbersome if there are too many.
Export results from Endnote to Covidence as an xml file. This is a quick process, and Covidence will check for any duplicates you have missed while importing. Make sure you check the duplicates are correct.
Screening on title and abstract in Covidence is quick and easy. Two (or more) reviewers can simply vote yes, no or maybe to include for full text review. Conflicts can be resolved by a third person or agreement between the original reviewers.
Full text PDFs can be uploaded in bulk to Covidence, or added individually to records.
Screening on full text will involve two or more reviewers voting independently to include or exclude, based on criteria that you have agreed. It is common to invite a third reviewer to resolve conflicts, or to make a joint decision.
Extraction 2.0 is a new process introduced to Covidence in 2020. This is more flexible than the previous system which focused on Cochrane methodology.
It is simple to export records from Covidence to Endnote, Excel and other software. Covidence also records the process in a PRISMA flow chart.
