Abstract: The normative debate surrounding whose preferences should be used in health state valuation has been widely covered with both discussion and empirical papers. The importance of this debate lies in how the use of different populations when generating health state utility values affects the results of economic evaluations, and hence decision-making. Following the same logic, the use of more general preference data from different populations is also likely to have an effect on decision-making.
This paper will contribute to the ongoing preference debate by considering an increasingly popular methodology used in health economics to elicit preferences, the discrete choice experiment (DCE). Using descriptive statistics from a review of recently conducted DCEs to inform this paper, the choice of whose preferences are typically elicited towards health care interventions will be investigated. It is found that the majority of DCE studies elicit the preferences of patients rather than the general public, in contrast to the dominance of general public preferences in health state valuation due to methodological arguments that feed into guidance documents e.g. those from the National Institute for Health and Care Excellence (NICE).
This paper aims to highlight the need for more discussion on whose preferences to elicit when using DCEs by raising various normative arguments that support the use of preferences from different populations. If DCEs are to be used in decision-making, as is often claimed, this area deserves greater attention.
