Evidence-based practice: a deconstruction and postmodern critique: book review article.
This paper discusses the significance of postmodernism for healthcare practice, specifically the discourse known as 'evidence-based practice'. It considers two texts, both of which present postmodern analyses of contemporary issues. One text presents a deconstruction of evidence-based practice in an attempt to reveal its 'true' nature, which is portrayed as one that does not respect research paradigms other than the randomised controlled trial, merely pays lip service to expertise and fails to connect with the real nature of clinical practice. The second text considers the accusation that absolute relativism implied by postmodern approaches may permit an 'anything goes' mentality and provide succour to those advocating unacceptable practices. A 'defence' of postmodernism in relation to the accusation that it encourages holocaust denial is used to consider further the nature and limitations of postmodern critiques of evidence-based practice. This review concludes that postmodernism fundamentally challenges the apparent 'objectivity' of evidence-based practice but it does not challenge the fundamental rules for acquiring and testing evidence. Rather it is the selection of questions to be asked and answered by evidence-based practice/practitioners that is the true limitation. This is the ground upon which fruitful argument can be had about the significance of evidence without undermining the requirement that there be evidence and standards to judge such evidence.
