Abstract
Promoting Clinical Effectiveness has a tone very different from earlier approaches of the executive. Two years ago purchasers were urged to put the use of clinical guidelines into contracts.2 This was advocated as a mechanism that could promote good practice, but it was untried and at best a blunt instrument: some guidelines were not even based on good evidence, to the embarrassment of those expected to work with them. In contrast, this recent publication is designed to be supportive, not prescriptive, and that in itself is a welcome change.
