ArticlePublication 2007Modeling HPV and Cervical Cancer in the U.S. for Analyses of Screening and Vaccination
This paper discusses a model of human papillomavirus (HPV) and cervical cancer that incorporates uncertainty …
This paper discusses a model of human papillomavirus (HPV) and cervical cancer that incorporates uncertainty about the natural history of disease that was used to provide quantitative insight into U.S. policy choices for cervical cancer prevention. The authors developed a stochastic microsimulation of cervical cancer that distinguishes different HPV types by their incidence, clearance, persistence, and progression. For each set of sampled input parameters, likelihood-based goodness-of-fit (GOF) scores were computed based on comparisons between model-predicted…

ArticlePublication 2007Cost Effectiveness of Interventions to Reduce Maternal Mortality in Mexico
This article, published in PloS One, uses maternal mortality data from Mexico to examine trends …
This article, published in PloS One, uses maternal mortality data from Mexico to examine trends in the provision of maternal health services and the trajectory towards reaching the Millennium Development Goal 5 (MDG 5). The authors developed a model of the natural history of pregnancy and pregnancy related complications and simulated a cohort of 15-year-old women over their lifetime based on national data. The model produced clinical outcomes, costs, and cost-effectiveness of the current standard…

ArticlePublication 2007Mortality-Risk Valuation and Age
This article addresses whether a single value of statistical life (VSL) should be applied to …
This article addresses whether a single value of statistical life (VSL) should be applied to all age groups or whether lower values should be used for the elderly, recognizing that their life expectancies are shorter than those of younger people. Surveys of different age groups' willingness to pay (WTP) for mortality-risk reductions can potentially help resolve this issue. The 36 studies reviewed suggest that the literature is split on whether older people have a lower WTP…

Tutorial/PrimerPublication, Teaching Resource 2005Refining Clinical Diagnosis with Likelihood Ratios
This article serves as a concise tutorial about the interpretation and use of likelihood ratios …
This article serves as a concise tutorial about the interpretation and use of likelihood ratios in clinical decision-making. Likelihood ratios can refine clinical diagnosis on the basis of signs and symptoms; however, they are underused for patients' care. A likelihood ratio is the percentage of ill people with a given test result divided by the percentage of well individuals with the same result. Ideally, abnormal test results should be much more typical in ill individuals…

ReportPublication 2003ISPOR Task Force Report: Good Practice for Decision Analytic Modeling in Health-Care
This report describes the consensus of a task force convened to provide modelers with guidelines …
This report describes the consensus of a task force convened to provide modelers with guidelines for conducting and reporting modeling studies. While published more than a decade ago, it remains a clearly written resource for thinking about how to accurately describe the components of models and their quality. Criteria for assessing the quality of models fell into three areas: model structure, data used as inputs to models, and model validation. Several major themes cut across…

ArticlePublication 2002Empirically Calibrated Model of Hepatitis C Virus Infection in the United States
This article presents an epidemiologic model of hepatitis C in the United States. The authors …
This article presents an epidemiologic model of hepatitis C in the United States. The authors used empirical calibration of model parameters to gain insights into uncertainty in the natural history of hepatitis C and to improve future projections. The authors identified model inputs by way of a systematic review. Model simulations were conducted and model predictions were compared with epidemiologic data on infection prevalence and mortality from liver cancer. Goodness-of-fit criteria were used to identify…

ArticlePublication 2000Valuing Mortality Risk: Theory and Practice
This article discusses the theoretical foundation and empirical methods for estimating the value of a …
This article discusses the theoretical foundation and empirical methods for estimating the value of a statistical life (VSL). VSL is defined by individuals' preferences for small changes in risk and income, and often used by environmental and other economists to measure the monetary value of reduced mortality risk. The article reviews the dependence of VSL on age, income, baseline mortality risk, and latency.
