6.P. Scientific session: Economic evaluation of health impacts for better decision choices

Abstract The strategy of Health in All Policies (HiAP) pursues to analyse the wider determinants of health affected by the decision-making process of traditionally non-health sectors, seeking to enhance population health benefits while avoiding health inequalities. This usually involves the use of health impact assessment (HIA) or health lens analysis to any policy, program, plan or project (PPPP), preferably prior to its implementation. On the other hand, decision-makers from a wide range of public and private sectors also demand a better insight of the meaning of the health impacts quantified under HIA. Assuming the (ubiquitous) situation of limited resources and budgets, decisions need to be based on cost effectiveness criteria and, whenever possible, direct and indirect health costs should be part of the impact assessment. Economic appraisal attempts to define whether a proposal makes a net contribution to social welfare, quantifying and valuing changes to individuals’ utility from the societal perspective, taking into account the impact of health on the individual, their family, employers, healthcare providers and the state. This approach can incorporate different components of the welfare costs of illness, including direct medical and paid care expenses, indirect lost opportunity costs such as productivity and the value of informal care time, as well as a value that monetises the disutility or pain and suffering associated with disease. The range of methods and estimated benefits can make it challenging to identify a best practice approach. The present session aims to address certain methodological aspects related to the economic evaluation of health impacts, which still generate some controversy and debate, with particular emphasis on the following topics: • Approaches for synthesizing evidence on health impact pathways and economic evaluation of health impacts for a better decision choice; • Health metrics: influence on the conclusions of economic analysis within HIA; • Sources of metrics used for economic analysis; • Uncertainties inherent to economic valuation of health outcomes: how to deal with it. Key messages • The economic analysis of health impacts can help prioritizing aspects with the greatest impact on population health, facilitating a more effective use of human and economic resources. • The economic analysis within HIA can improve decision-making but requires careful consideration of health metrics, sourcing of data, and management of uncertainties.
