ArticlePublication 2013Valuing Health Risk Reductions
In this article, the authors discuss how to value risk reductions in the context of …
In this article, the authors discuss how to value risk reductions in the context of benefit-cost analysis. Many public policies and private actions affect the risk of injury, illness, or death, yet changes in these risks are not easily valued using market prices. The authors begin with a pragmatic focus, describing the analytic framework and the approaches currently used for valuation, including estimates of willingness to pay (WTP), cost of illness (COI), and monetized quality-adjusted…

ReviewPublication 2013Valuing the Economic Benefits of Complex Interventions
This is a review of economic evaluations of complex health interventions. Complex interventions, involving interlinked …
This is a review of economic evaluations of complex health interventions. Complex interventions, involving interlinked packages of care, challenge the application of current methods of economic evaluation that focus on measuring only health gain. The authors find that complex interventions may be problematic on two levels. First, the complexity means the intervention may not fit into one of the current appraisal systems, and/or second, maximizing health is not the only objective. This paper discusses the…

GuidelinesPublication 2012Model Transparency and Validation: A Report of the ISPOR-SMDM Modeling Task Force-7
This paper discusses how to improve trust in the use of health care models through …
This paper discusses how to improve trust in the use of health care models through validation and transparency. Validation involves face validity (wherein experts evaluate model structure, data sources, assumptions, and results), verification or internal validity (check accuracy of coding), cross validity (comparison of results with other models analyzing same problem), external validity (comparing model results to real-world results), and predictive validity (comparing model results with prospectively observed events). Recommendations are provided for nontechnical description…

GuidelinesPublication 2012Dynamic Transmission Modeling: A Report of the ISPOR-SMDM Modeling Task Force-5
This paper reports the consensus-based guidelines on dynamic transmission modeling in health care. The transmissible …
This paper reports the consensus-based guidelines on dynamic transmission modeling in health care. The transmissible nature of communicable diseases is what sets them apart from other diseases modeled by health economists. The probability of a susceptible individual becoming infected at any one point in time (the force of infection) is related to the number of infectious individuals in the population, will change over time, and will feed back into the future force of infection. These…

GuidelinesPublication 2012Modeling Using Discrete Event Simulation: A Report of the ISPOR-SMDM Modeling Task Force-4
This paper reports on consensus-based guidelines on the application of DES in a health care …
This paper reports on consensus-based guidelines on the application of DES in a health care setting, covering the range of issues to which DES can be applied. Discrete event simulation (DES) is a form of computer-based modeling that provides an intuitive and flexible approach to representing complex systems. The article works through the different stages of the modeling process: structural development, parameter estimation, model implementation, model analysis, and representation and reporting. Recommendations are made for…

GuidelinesPublication 2012Model Parameter Estimation and Uncertainty Analysis: A Report of the ISPOR-SMDM Modeling Task Force-6
This paper discusses methods for the reporting of uncertainty, both in terms of deterministic sensitivity …
This paper discusses methods for the reporting of uncertainty, both in terms of deterministic sensitivity analysis techniques and probabilistic methods. Stochastic (first-order) uncertainty is distinguished from both parameter (second-order) uncertainty and from heterogeneity, with structural uncertainty relating to the model itself forming another level of uncertainty. The article describes the process of estimating model inputs, whether these are point estimates or distributions. It also explores the link between parameter uncertainty, decision uncertainty, and value-of-information analysis.…

ArticlePublication 2012Expert Elicitation of VSL
This article uses expert elicitation to address the monetary value of avoided premature mortality, which …
This article uses expert elicitation to address the monetary value of avoided premature mortality, which typically dominates the quantified benefits of air pollution regulations. Formal expert elicitation methods are one means of characterizing associated uncertainties. The authors undertake a pilot study that elicits quantitative probabilistic judgments of uncertainties in value per statistical life (VSL) estimates for use in an air pollution context. The two-stage elicitation addresses uncertainties in both a base case VSL for a…

ReportPublication 2012Mortality Risks in Environment, Health and Transport
This report presents a major meta-analysis of value of a statistical life (VSL) estimates derived …
This report presents a major meta-analysis of value of a statistical life (VSL) estimates derived from surveys around the world. The analysis seeks to explain the differences in the estimates, for example across countries. Differences in incomes and the magnitude of the risk reduction were found to be the factors having the strongest impact, but numerous other policy-relevant factors are also important. The report also presents advice on how VSL estimates can be best used…

This article focuses on the value of mortality risk reduction, an important component of the benefits estimates for environmental policies. In recent years, the number, scope, and quality of valuation studies have increased dramatically. Revealed-preference studies of wage compensation for occupational risks, on which analysts have primarily relied, have benefited from improved data and statistical methods. Stated-preference research has improved methodologically and expanded dramatically. In these studies, researchers have explored many issues concerning the validity…
