PD56 Conceptual Issues In The Valuation Of Health States In Children

Abstract

IntroductionAssessing the cost utility of health technologies for pediatric patients requires robust utility values for child health states, but the methods for valuing these pediatric health states are much less established than those for valuing adult health states. This is partly because the elicitation of preferences for child health states poses many normative, ethical, and practical challenges.MethodsThis presentation examines the conceptual issues in the valuation of health states in children by addressing the following questions.(i)Normative theories of health state values: What are we attempting to elicit?(ii)Sources of preferences: Whose preferences should we elicit, and from which perspective?(iii)Valuation methodologies: How should we elicit preferences?(iv)Attaching different values to child and adult health: Is a lack of consistency problematic?To answer these questions, we used desk research (non-systematic literature reviews) and findings from a two-part workshop held in April 2021. The workshop included 25 participants with expertise in health economics, health state valuation, child health, health technology assessment (HTA) decision-making, and ethics.ResultsWe identified a lack of consensus on what is being elicited for both adults and children. Many HTA agencies recommend that the public be involved in utility generation exercises, but some criteria for defining who constitutes a member of the public exclude children. Of the many candidate sample types, perspectives, and methodologies, only a few were deemed relevant, acceptable, and feasible for use in the child health context. In addition, there were diverging views on whether it is possible to compare and integrate adult and child value sets with different properties.ConclusionsSeveral questions remain to be answered before the public and other stakeholders can have confidence in child health state valuation protocols. We propose a research agenda, including both empirical and conceptual work, to inform future methodological development and to help HTA agencies make recommendations about how child utility values should be generated.
