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 2012Conceptualizing a Model: A Report of the ISPOR-SMDM Modeling Task Force-2
This article provides a series of consensus-based best practices regarding the process of model conceptualization, …
This article provides a series of consensus-based best practices regarding the process of model conceptualization, specifically when models are used to inform medical decisions and health-related resource allocation. The authors divide the conceptualization process into two distinct components: the conceptualization of the problem, which converts knowledge of the health care process or decision into a representation of the problem, followed by the conceptualization of the model itself, which matches the attributes and characteristics of a…

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.…

GuidelinesPublication 2011Calibrating Models in Economic Evaluation
This article provides guidance on the theoretical underpinnings of different calibration methods used for mathematical …
This article provides guidance on the theoretical underpinnings of different calibration methods used for mathematical models for economic evaluations. The calibration process is divided into seven steps and different potential methods at each step are discussed, focusing on the particular features of disease models in economic evaluation. The seven steps are (i) Which parameters should be varied in the calibration process? (ii) Which calibration targets should be used? (iii) What measure of goodness of fit…

GuidelinesWeb Portal 2017iDSI Reference Case for Economic Evaluation
This is a reference case which gives 12 principles to guide the planning, conduct and …
This is a reference case which gives 12 principles to guide the planning, conduct and reporting of health economic evaluations in low- and middle-income countries (LMICs). The International Decision Support Group (iDSI) is a network of health, policy and economic experts. It builds on the approaches of the National Institute for Health and Care Excellence (NICE) in the UK, the Health Intervention and Technology Assessment Program (HITAP) in Thailand and the World Health Organization. iDSI…

This “Frequently Asked Question” style document gives a brief overview of Regulatory Impact Analysis (RIA), …
This “Frequently Asked Question” style document gives a brief overview of Regulatory Impact Analysis (RIA), a method used by the US government to assess the consequences of proposed policies and their alternatives. The document is aimed at those who are new to the topic. RIAs apply a framework for collecting, organizing, and evaluating data. They help ensure that regulatory actions are justified and necessary to achieve social goals, and that these actions are implemented in the…

GuidelinesPublication 2016Methods for Health Economic Evaluation of Vaccines
This article describes the development of a consensus for health economic evaluations of vaccines to …
This article describes the development of a consensus for health economic evaluations of vaccines to support the development of national guidelines in Europe. While guidelines advocating more standardization of health economic evaluations exist, this article aims to address several immunization-specific aspects (e.g. indirect effects or discounting approach) which are still a subject of debate. The systematic literature review search was informed by expert opinion. 2,838 articles were returned from the search and 26 were finally…

GuidelinesPublication 2016Multiple Criteria Decision Analysis
This ISPOR task force report provides an introduction to multiple criteria decision analysis (MCDA) - …
This ISPOR task force report provides an introduction to multiple criteria decision analysis (MCDA) - it defines MCDA; provides examples of its use in different kinds of decision making in health care (including benefit risk analysis, health technology assessment, resource allocation, portfolio decision analysis, shared patient clinician decision making and prioritizing patients’ access to services); provides an overview of the principal methods of MCDA; and describes the key steps involved. In 2014, ISPOR established an…
