Setting priorities in the new NHS: can purchasers use cost-utility information?

It could be argued that the success of the new NHS depends, to some extent, on the production of accurate cost-utility information. This raises questions about the quality of this information, whether it can be transferred from one study setting to another and whether such information can reasonably be used 'at the negotiating table'. The quality of some studies is open to question. Some agreement is needed on issues of principle and more work is required to make cost-utility analyses more applicable locally.
