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…

ArticlePublication 2010Health and Economic Impact of Rotavirus Vaccination in GAVI-Eligible Countries
Rotavirus infection is responsible for about 500,000 deaths annually, and the disease burden is disproportionately …
Rotavirus infection is responsible for about 500,000 deaths annually, and the disease burden is disproportionately borne by children in low-income countries. Motivated by the global recommendation by the WHO that all countries include infant rotavirus vaccination in their national immunization programs, the objective of this analysis was to provide information on the expected health, economic and financial consequences of rotavirus vaccines in the 72 GAVI support-eligible countries. The authors synthesized population-level data from various sources (primarily from…

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…

This encyclopedia addresses both prescriptive and descriptive decision making through a conceptual structure consisting of six components of classical decision analysis. It includes articles that have been prepared by more than 200 contributors from around the world. The alphabetical organization of the encyclopedia facilitates access to information. A Reader’s Guide, organized by category of the decisionmaking process includes the following 7 components: Identification of the decision maker - in other words, who must choose. In general, there…

ArticlePublication 2009Cost-Effectiveness of Rotavirus Vaccination in Vietnam
This article reports on a cost-effectiveness analysis of rotavirus vaccination, including varying degrees of severity, …
This article reports on a cost-effectiveness analysis of rotavirus vaccination, including varying degrees of severity, age-dependency of clinical manifestation, and additional features of the disease (e.g., the possibility of reinfection and varying degrees of partial immunity conferred by natural infection). The authors developed a Markov model that reflects key features of rotavirus infection, using the most recent data available at the time of their analysis. They applied the model to the 2004 Vietnamese birth cohort…

ArticlePublication 2008Mathematical Models of Cervical Cancer Prevention in the Asia Pacific Region
This article reports on a model-based approach to estimate averted cervical cancer cases and deaths, …
This article reports on a model-based approach to estimate averted cervical cancer cases and deaths, disability-adjusted life years (DALYs) and incremental cost-effectiveness ratios (I$/DALY averted) for vaccination of young adolescent girls against human papillomavirus (HPV) types 16 and 18. The authors used population-based and epidemiologic data for 25 countries in Asia (22 GAVI-Alliance eligible countries, Thailand, China and Japan). They found that an absolute reduction in lifetime cancer risk varied across countries, depending on incidence,…

This article reports on a model-based approach estimated averted cervical cancer cases and deaths, disability-adjusted …
This article reports on a model-based approach estimated averted cervical cancer cases and deaths, disability-adjusted life years (DALYs) and incremental cost-effectiveness ratios (I$/DALY averted) for human papillomavirus (HPV) vaccination of young adolescent girls using population and epidemiologic data for 33 countries in Latin America and the Caribbean (LAC). The authors found that an absolute reduction in lifetime cancer risk varied between countries, depending on incidence, proportion attributable to HPV-16 and 18, and population age-structure; for…

ArticlePublication 2008Development of an Empirically Calibrated Model of Gastric Cancer in Two High-Risk Countries
This paper presents an empirically calibrated mathematical model of gastric cancer and H. pylori in …
This paper presents an empirically calibrated mathematical model of gastric cancer and H. pylori in China and Colombia to provide qualitative insight into the cost-effectiveness of gastric cancer prevention strategies. Despite studies that have established the relationship between Helicobacter pylori and gastric cancer and H. pylori treatment reducing cancer incidence among individuals without preexisting precancerous lesions, screening for H. pylori is still being debated. The authors synthesized…!--?xml:namespace prefix = "o" ns = "urn:schemas-microsoft-com:office:office" /-->

This review examines the modelling approaches used in cost-effectiveness analyses (CEAs) of vaccination programs. After …
This review examines the modelling approaches used in cost-effectiveness analyses (CEAs) of vaccination programs. After overviewing the key attributes of models used in CEAs, a framework for categorizing theoretical models is presented. Categories are based on three main attributes: static/dynamic; stochastic/deterministic; and aggregate/individual based.
