ArticlePublication 2022Early HPV Natural History Transitions
Microsimulation models used to evaluate the cost-effectiveness of novel cervical cancer screening technologies rely on …
Microsimulation models used to evaluate the cost-effectiveness of novel cervical cancer screening technologies rely on accurate transition risks for human papillomavirus (HPV) infection, persistence (or absence of HPV clearance), progression to precancerous lesions, and invasion. To inform the refinement of such models, we compared the early natural history of HPV types using prospective data from immunocompetent women in the Guanacaste Natural History Study, the ASCUS-LSIL Triage Study, and the Costa Rica HPV Vaccine Trial. We…

ArticlePublication 2019Estimating the Total Incidence of Global Childhood Cancer: A Simulation-Based Analysis
This study describes the development of a microsimulation model to simulate childhood cancer incidence for …
This study describes the development of a microsimulation model to simulate childhood cancer incidence for 200 countries/territories, taking into account trends in population growth and urbanicity, geographical variation in cancer incidence, and health system barriers to access and referral that contribute to underdiagnosis. The model was calibrated to publicly available cancer registry data, and the total incidence of childhood cancer (diagnosed and undiagnosed) was estimated for each country in 2015 and projections made to 2030.…

ArticlePublication 2019Projected U.S. State-Level Prevalence of Adult Obesity and Severe Obesity
This analysis estimates state-specific and demographic subgroup-specific trends and projections of the prevalence of categories …
This analysis estimates state-specific and demographic subgroup-specific trends and projections of the prevalence of categories of body-mass index (BMI) in the United States. Self-reported BMI from the Behavioral Risk Factor Surveillance System Survey (1993-1994 and 1999-2016) were obtained and corrected for quantile-specific self-reporting bias. Multinomial regressions were then fitted for each state and subgroup to estimate the prevalence of four BMI categories from 1990 through 2030: underweight or normal weight (BMI <25), overweight (25 to…

ArticlePublication 2022Duration & Cost-Effectiveness of Hepatocellular Carcinoma Surveillance in Hepatitis C Patients After Viral Eradication
This study assesses the cost-effectiveness of biannual surveillance for hepatocellular carcinoma (HCC) in patients cured …
This study assesses the cost-effectiveness of biannual surveillance for hepatocellular carcinoma (HCC) in patients cured of hepatitis C virus (HCV) using oral direct-acting antivirals (DAAs). A microsimulation model of HCC natural history in individuals with HCV-related advanced fibrosis or cirrhosis post-DAAs was developed, integrating data on HCC incidence, tumor progression, surveillance adherence, and health state costs/utilities. Biannual ultrasound and alpha-fetoprotein surveillance were compared to no surveillance over varying durations (5 years to lifetime). Results indicate…

ArticlePublication 2022Cost-Effectiveness of Screening for Atrial Fibrillation Using Wearable Devices
This economic evaluation assesses the cost-effectiveness of atrial fibrillation (AF) screening strategies, particularly utilizing wrist-worn …
This economic evaluation assesses the cost-effectiveness of atrial fibrillation (AF) screening strategies, particularly utilizing wrist-worn wearable devices, to prevent strokes. Conducted using a microsimulation decision-analytic model, the study spans from September 8, 2020, to May 23, 2022, incorporating 30 million simulated individuals representative of the US population aged 65 years or older. Eight screening strategies, including six employing wrist-worn devices and two using traditional methods, were compared against no screening. Results indicate that all wrist-worn…

ArticlePublication 2021Rational Policymaking during a Pandemic
Policymaking during a pandemic can be extremely challenging. As COVID-19 is a new disease and …
Policymaking during a pandemic can be extremely challenging. As COVID-19 is a new disease and its global impacts are unprecedented, decisions are taken in a highly uncertain, complex, and rapidly changing environment. In such a context, in which human lives and the economy are at stake, the authors argue that using ideas and constructs from modern decision theory, even informally, will make policymaking a more responsible and transparent process.

ArticlePublication 2020Perceptions of COVID-19 around the World
This study evaluates public risk perception of COVID-19 around the world in ten countries across …
This study evaluates public risk perception of COVID-19 around the world in ten countries across Europe, America, and Asia. They found that significant predictors of risk perception included personal experience with the virus, individualistic and prosocial values, hearing about the virus from friends and family, trust in government, science, and medical professionals, personal knowledge of government strategy, and personal and collective efficacy. Although there was substantial variability across cultures, individualistic worldviews, personal experience, prosocial values,…

ReportPublication 2021Valuing COVID-19 Mortality and Morbidity Risks
In this report, the researchers develop an approach for valuing COVID-19 mortality and morbidity risk …
In this report, the researchers develop an approach for valuing COVID-19 mortality and morbidity risk reductions that builds on the U.S. Department of Health and Human Services (HHS) Guidelines for Regulatory Impact Analysis. They review the differences between COVID-19 mortality risks and the types of risks that are more commonly studied, and find that the impacts of these differences on the value of mortality risk reductions (the value per statistical life, VSL) are uncertain. They…

ArticlePublication 2020Valuing COVID-19 Mortality Risk
In this article, the author evaluates whether conventional estimates of the value per statistical life …
In this article, the author evaluates whether conventional estimates of the value per statistical life (VSL) in the United States (about $10 million) are appropriate for evaluating policies that affect risk of COVID-19. This estimate may be too large, because: (1) VSL estimates marginal values but COVID-19 risks can be non-marginal; (2) VSL is estimated for the average resident, but COVID-19 mortality is concentrated among the elderly; and (3) the pandemic has caused substantial losses…
