Disseminators vs revisionists: attitudes to the ‘implementation gap’ in evidence‐based practice

Ambiguities in the term ‘evidence‐based practice’ (EBP) are often used to hide some of the tensions within the idea itself. This article seeks to clarify what EBP means and how evidence and knowledge can contribute to the development of children's services. It acknowledges the ‘implementation gap’ between evidence‐based practice and evidence‐based practitioners, and discusses two contrasting perspectives on the problem and its solution. For ‘disseminators’ the primary issue is better translation of findings into practice, illustrated here by the work of the National Institute of Health and Clinical Excellence (NICE). ‘Revisionists’ look beyond obstacles and drivers to implementation and instead advocate looking again at the relationship between research and practice and propose a number of radical proposals for how this relationship can be re‐envisioned.
