ReviewPublication 2012Modeling Preventative Strategies Against HPV-Related Disease in Developed Countries
This review article is part of a special supplement on “Comprehensive Control of HPV Infections …
This review article is part of a special supplement on “Comprehensive Control of HPV Infections and Related Diseases.” At the time of its writing, prophylactic vaccination against human papillomavirus (HPV) in pre-adolescent females had been introduced in most developed countries, supported by modeled evaluations that had almost universally found vaccination of pre-adolescent females to be cost-effective. Vaccination of pre-adolescent males had been shown to be cost-effective at a cost per vaccinated individual of ~US$400-500 if…

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 2012State-Transition Modeling: A Report of the ISPOR-SMDM Modeling Task Force-3
State-transition modeling includes both Markov model cohort simulation as well as individual-based (first-order Monte Carlo) …
State-transition modeling includes both Markov model cohort simulation as well as individual-based (first-order Monte Carlo) microsimulation. These models have been used in many different populations and diseases, and their applications range from personalized health care strategies to public health programs. Most frequently, state-transition models are used in the evaluation of risk factor interventions, screening, diagnostic procedures, treatment strategies, and disease management programs. Recommendations are made on choice of model type (cohort vs. individual-level model), model…

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 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…

ReviewPublication 2010Validation of Population-Based Disease Simulation Models: A Review
This article develops a framework for validating population-based chronic disease simulation models, and reviews the …
This article develops a framework for validating population-based chronic disease simulation models, and reviews the principles and methods for such models. While computer simulation models are used increasingly to support public health research and policy, questions about their quality persist. Based on the review, the authors formulated a set of recommendations for gathering evidence of model credibility. They find that evidence of model credibility derives from examining: 1) the process of model development, 2) the…

ReviewPublication 2006Ethical Issues in Resource Allocation, Research, and New Product Development
Ethical dilemmas arising in setting priorities among interventions and among individuals in need of care …
Ethical dilemmas arising in setting priorities among interventions and among individuals in need of care are most acute when needs are great and resources few. This chapter from the Disease Control Priorities in Developing Countries 2nd edition addresses some of these concerns, identifying some of the principal ethical issues that arise in the development and allocation of effective interventions for developing countries and discussing some alternative resolutions. Resource allocation in health and elsewhere should satisfy two main…

ReviewPublication 2004Decision Analysis Applications in Operations Research
This article reviews trends and developments in decision analysis applications, based primarily on a survey of …
This article reviews trends and developments in decision analysis applications, based primarily on a survey of decision analysis applications published in the period 1990–2001 in major English-language operations research and closely related journals. It serves as a guide to those interested in recent applications in specific areas or in applications that illustrate the use of particular methods. The authors identify and discuss noteworthy trends in, and developments affecting, published applications, including those in computer software and…
