Eliciting reasons: empirical methods in priority setting.

In this paper I review empirical methods applied in recent analysis of decision-making on priorities in health care. I outline a number of discrete methods and discuss their applicability and efficacy in the field of bioethics. Three key methodological issues seem to be important: choice of subject group; choice of approach and the extent of background information given to respondents. I conclude that a combination method is needed to give a comprehensive representation of values in priority setting and thus to meet the overall objectives of empirical ethics.
