Description of session: Including diverse types of evidence in systematic reviews can increase their relevance for decision makers. Qualitative Evidence Syntheses (QES) bring together research that reports people’s views and experiences of, for example, a particular illness or healthcare approach. As well as being of value in themselves, QES can assist policy makers with interpretation and implementation of the findings of systematic reviews that evaluate intervention effectiveness. The session will begin with an overview of the underlying logic and methods of QES. It will then describe some examples of QES to exemplify how they can assist policy development. Finally, the session will describe a current QES being undertaken at NUI Galway on the factors that impact on recruitment to trials in healthcare.
