Abstract.This paper critiques particular aspects of the published UK government Department of Health’s proposal to promote ‘The Expert Patient’ as a way of enhancing patient autonomy and reducing reliance on limited health care resources. Although the broad aims of the report are supported the detail is criticised on the basis that lack of clarity over key terms, including ‘expert’ ‘illness’ and ‘disease’, means that there is no clear focus for action and threatens to undermine the effectiveness of the proposals.
