ArticlePublication 2015Population Health Model (POHEM): An Overview
This paper provides an overview of the rationale, methodology and applications of the Population Health …
This paper provides an overview of the rationale, methodology and applications of the Population Health Model (POHEM). POHEM is a health microsimulation model, developed at Statistics Canada in the early 1990s. The authors describe that POHEM draws together rich multivariate data from a wide range of sources to simulate the lifecycle of the Canadian population, specifically focusing on aspects of health. The model dynamically simulates individuals’ disease states, risk factors, and health determinants, in order…

ArticlePublication 2019Estimation of Eating Disorders Prevalence by Age and Associations with Mortality in a Simulated Nationally Representative U.S. Cohort
This analysis models the individual-level disease dynamics of eating disorders (ED) in the United States, …
This analysis models the individual-level disease dynamics of eating disorders (ED) in the United States, and estimates the association of increased treatment coverage with ED-related mortality. Using an individual-level Markov state transition model calibrated to nationally-representative US survey data from 2007 and 2011, the authors simulated a virtual cohort of 100,000 individuals (50% male) from birth to age 40 years and modelled 4 ED diagnoses: anorexia nervosa, bulimia nervosa, binge eating disorder, and other specified…

ArticlePublication 2021Individual and Social Determinants of COVID-19 Vaccine Uptake
This article examined the individual, communication and social determinants associated with COVID-19 vaccine uptake using …
This article examined the individual, communication and social determinants associated with COVID-19 vaccine uptake using national survey data collected before vaccines were available in the U.S. Of note, individuals under the federal poverty level and racial and ethnic minorities were oversampled. Outcomes included the likelihood of vaccinating self and dependents (e.g., children). Independent variables included perceptions of risk, exposure to different media for COVID-19 news, political party identification, confidence in scientists and social determinants of…

ArticlePublication 2021Health Opportunity Cost Threshold for CEA in the U.S.
Using a modeled cohort of 100,000 individuals in the United States with private health insurance, …
Using a modeled cohort of 100,000 individuals in the United States with private health insurance, the authors simulated the short-term mortality and morbidity resulting from increased premium related cancelation of insurance coverage. The authors used this model to estimate cost-effectiveness thresholds, in dollars per quality-adjusted life year (QALY) gained based on health opportunity costs. They reported the number of persons who dropped insurance coverage, resulting number of additional deaths and QALYs lost from mortality and…

ArticlePublication 2018Comparing Cost-per-QALYs Gained to Cost-per-DALYs Averted
The authors examined 6,438 cost-per-QALY and 543 cost-per-DALY studies published through 2016 using two databases, …
The authors examined 6,438 cost-per-QALY and 543 cost-per-DALY studies published through 2016 using two databases, the Tufts Medical Center CEA Registry (cost-per-QALY gained studies), and the Global Cost-Effectiveness Analysis (GHCEA) Registry (cost-per-DALY averted studies). Study characteristics that were analyzed included intervention type, sponsor, country, primary disease, and number of CEAs versus disease burden estimates for major conditions. The authors report that cost-per-QALY studies were most often about pharmaceuticals or interventions in high-income countries while cost-per-DALY…

ArticlePublication 2016Redrawing the U.S. Obesity Landscape: State-Specific Adult Obesity Prevalence
State-level estimates from the Centers for Disease Control and Prevention (CDC) underestimate the obesity epidemic …
State-level estimates from the Centers for Disease Control and Prevention (CDC) underestimate the obesity epidemic because they use self-reported height and weight. This study described a novel bias-correction method and produced corrected state-level estimates of obesity and severe obesity. Using non-parametric statistical matching, the authors adjusted self-reported data from the Behavioral Risk Factor Surveillance System (BRFSS) 2013 (n = 386,795) using measured data from the National Health and Nutrition Examination Survey (NHANES) (n = 16,924).…

This article discusses three challenges of using cost-effectiveness thresholds to inform whether a third-party payer …
This article discusses three challenges of using cost-effectiveness thresholds to inform whether a third-party payer will fund a particular service. First, how is the appropriate cost-effectiveness threshold - or threshold range - to be determined? (And should there be a single threshold or multiple thresholds?) Second, how can the valuation of health benefits be refined to better capture the value of treatments to patients and to the economy as a whole? Third, how should a…

ArticlePublication 2013Validation and Calibration of a Simulation Model of Pediatric HIV Infection
The authors developed a microsimulation model of pediatric HIV disease progression using the Cost-Effectiveness of …
The authors developed a microsimulation model of pediatric HIV disease progression using the Cost-Effectiveness of Preventing AIDS Complications (CEPAC) model framework. This CEPAC-Pediatric model was then validated by varying CD4 data and comparing the corresponding model-generated survival curves to empirical survival curves obtained from the International Epidemiologic Database to Evaluate AIDS (IeDEA). The model was calibrated to other African countries by systematically varying immunologic and HIV mortality-related input parameters. In the calibration analyses, the model-generated…

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…
