Cost and price in the NHS: the importance of monetary value in the decision-making framework--the case of purchasing renal replacement therapy.

This paper examines the role of cost, price and health economic evaluation in the National Health Service as demonstrated by reference to renal replacement therapy for patients with end-stage renal failure. In particular, it aims to highlight the problems with monetary value and to illustrate how it may be manipulated by legitimate techniques to produce varying outcome values which may be misleading and thereby distort the healthcare decision-making process. The paper argues for standardization of costing methods and health economic evaluation to enable meaningful intra- and inter-hospital comparisons to be made.
