Developing methods that really do value the 'Q' in the QALY.

Most health economists recommend that improvements in health be valued by asking members of the general public to imagine themselves in different states of health and then to think about how many years of life they would give up or what risk of death they would be willing to accept in order to be in full health. In this paper, I argue that preferences are not a very good guide to future experiences and a more suitable way to value health is to ask people in different states of health how they think and feel about their lives. Valuing health in this way may result in greater priority being given to mental health services. Whatever the precise implications, it is my contention that it is much better to ration health care according to real experiences rather than according to hypothetical preferences.
