ArticlePublication 2017Likelihood Approach for Calibration of Stochastic Epidemic Models
Stochastic transmission dynamic models are especially useful for studying the early emergence of novel pathogens …
Stochastic transmission dynamic models are especially useful for studying the early emergence of novel pathogens given the importance of chance events when the number of infectious individuals is small. However, methods for parameter estimation and prediction for these types of stochastic models remain limited. This paper describes a calibration and prediction framework for stochastic compartmental transmission models of epidemics. The proposed method applies a linear noise approximation to describe the size of the fluctuations, and…

ArticlePublication 2016Identifying Cost-Effective Dynamic Policies to Control Epidemics
This paper describes a mathematical decision model for identifying dynamic health policies for controlling epidemics. …
This paper describes a mathematical decision model for identifying dynamic health policies for controlling epidemics. The dynamic policies aim to select the best current intervention based on accumulating epidemic data and the availability of resources at each decision point. An algorithm is proposed to approximate dynamic policies that optimize the population's net health benefit, a performance measure which accounts for both health and monetary outcomes. The authors further illustrate how dynamic policies can be defined and…

ArticlePublication 2011Dynamic Policies for Controlling Spread of Emerging Infections
This paper illustrates the design and implementation of a dynamic health policy for the control …
This paper illustrates the design and implementation of a dynamic health policy for the control of a novel strain of influenza, where two types of interventions are assumed to be available during the epidemic: (1) vaccines and antiviral drugs, and (2) transmission reducing measures, such as social distancing or mask use, that may be turned "on" or "off" repeatedly during the course of epidemic. A modeling approach is described for developing dynamic health policies that allow…

ArticlePublication 2023Valuing Mortality Risk: Per Life, Life Year, or QALY?
It is important to consider age and other relevant factors when assessing the value associated …
It is important to consider age and other relevant factors when assessing the value associated with reducing risks to ensure a comprehensive and accurate understanding of its impact. In a recent paper, it is explained that the value of risk reduction, whether it is a temporary or persistent reduction, can be defined using the "value per statistical life" (VSL), "value per statistical life year" (VSLY), or "value per quality-adjusted life year" (VQALY).

ArticlePublication 2021Incorporating Equity in Infectious Disease Modeling: Measles
Deterministic compartmental models of infectious diseases like measles typically reflect biological heterogeneities in the risk …
Deterministic compartmental models of infectious diseases like measles typically reflect biological heterogeneities in the risk of infection and severity to characterize transmission dynamics. Given the known association of socioeconomic status and increased vulnerability to infection and mortality, it is also critical that such models further incorporate social heterogeneities. This article explores the influence of integrating income-associated differences in parameters of traditional dynamic transmission models. The authors developed a measles “SIR” model, in which the

ArticlePublication 2022Systematic Review of Patient Preferences, Expectations, and Values for Management and Treatment of Hypertension
This analysis summarized the evidence on the preferences, expectations, and values of hypertension management and …
This analysis summarized the evidence on the preferences, expectations, and values of hypertension management and treatment in hypertensive patients. The authors reviewed 24 studies involving 8,701 participants. Despite varying areas of focus, common themes included (1) patients often obtain hypertension information from their physicians and prefer shared patient-centered decision-making, and (2) side effects, cost, and convenience are important factors for patients when selecting a treatment regimen for hypertension.

ArticlePublication 2022Estimating Joint Health State Utilities
Estimating health utility for a health state defined by a single health condition is relatively …
Estimating health utility for a health state defined by a single health condition is relatively straightforward but becomes more complicated when 2 or more health conditions co-occur. Estimating health utility for so-called “joint health states” is particularly critical for health conditions that commonly co-occur with other conditions or for treatments in which adverse events are common or serious. In these cases, ignoring the utility loss associated with the joint health state can bias CEA results…

Problematic alcohol use is known to harm individuals surrounding the drinker. This study described the health utility of people who reported having a family member(s) whom they perceived as a “problem drinker.” Using a US population dataset, and adjusting for other drinking-related factors, perceiving a family member as a problem drinker was associated with lower health utility on the order of 0.033 (P < 0.001) for a spouse/partner to 0.023 (P < 0.001) for a…

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,…
