Utility of evidence synthesis
Systematic reviews and evidence syntheses can play an important role in facilitating knowledge exchange between researchers and evidence users. One critical factor in enabling a review to be used is to ensure that the review is useful.
Systematic reviews in public health, especially within the field of healthy public policy, often address broad questions, and incorporate high levels of complexity. Preparing rigorous systematic reviews which address these policy relevant questions can present many methodological challenges which can result in delays, and in dense text which obscure the key messages of interest and relevance to evidence users.
We have developed considerable expertise on the conduct of complex policy relevant reviews and are keen to promote the conduct of useful reviews. This work covers a range of projects. This includes methods which we have developed to improve the visual presentation of complex quantitative and qualitative data, knowledge translation work, and collaborative work with the Cochrane Public Health Group. The latter project involved qualitative interviews with review users and review authors to investigate how reviews are used, what are the barriers to the use and production of relevant reviews, and what are the characteristics of useful reviews.
