Measuring the economic impact of environmental stressors on health

Abstract Environmental stressors are an important source of burden of disease worldwide. The accurate economic evaluation of health hazards caused by environmental stressors guide the design of more effective and comprehensive public policies. However, guidelines on cost assessment, monetisation and discounting methodologies are scarce. Therefore, several different methodologies are applied in multiple contexts, making comparability difficult. Within BEST-COST, methods for monetising health hazards caused by environmental stressors are identified and described based on a systematic review approach. An electronic search was performed in Medline, Scopus, Web of Science and Econlit, alongside with grey literature and citation and reference tracking identifying all relevant studies. Different methods are identified, such as value of a statistical life (VSL) and value of a life year (VOLY), as well as specificities from data collection to modelling for the economic evaluation. These methods may be categorised based on their approach (market-based or non-market based), perspective of analysis (payer, patient or societal) and health measures. In this presentation, the various key methodologies to assess the economic impact of environmental stressors on health will be introduced and demonstrated. Through these insights, workshop participants will be supported in performing health impact assessments and cost-benefit analyses, which play a pivotal role in informing public policies that impact environment and subsequently health.
