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 2016Cost-Effectiveness of Intensive Blood Pressure Management
This article aimed to evaluate the cost-effectiveness of intensive blood pressure management compared with standard …
This article aimed to evaluate the cost-effectiveness of intensive blood pressure management compared with standard management among 68-year-old high-risk adults with hypertension but not diabetes. A Markov cohort model was developed to estimate lifetime costs and quality-adjusted life-years (QALYs) discounted at 3% annually. The Systolic Blood Pressure Intervention Trial (SPRINT) was used to estimate treatment effects and adverse event rates. The authors used Centers for Disease Control and Prevention Life Tables to project age- and…

ArticlePublication 2016Measuring Benefits of Opioid Misuse Treatment: HRQOL of Opioid-Dependent Individuals and Spouses
This study sought to understand how the general public views the quality of life effects …
This study sought to understand how the general public views the quality of life effects of opioid misuse and opioid use disorder on an individual and his/her spouse, measured in terms used in economic evaluations. The study design was a cross-sectional internet survey of a US population-representative respondent panel conducted December 2013-January 2014, with a total of 2054 randomly selected adults, of whom 51.1% were male. The mean individual utility ranged from 0.574 for active injection…

ArticlePublication 2016Accounting for Technical, Ethical, and Political Factors in Priority Setting

This article investigates two cases of priority setting to explore how, in addition to technical considerations, ethical and political factors shape the allocation of health resources. First, they discuss how Thai authorities adjudicated a coverage decision for HLA-B*1502 screening, which meets the national cost-effectiveness threshold for only some of the conditions it can detect. Second, they consider England’s Cancer Drugs Fund to investigate the interplay of technical decision making and political reality. The findings suggest four concluding…

ArticlePublication 2015Cancer Models and Real-World Data: Better Together
Decision-analytic models synthesize available data on disease burden and intervention effectiveness to project estimates of …
Decision-analytic models synthesize available data on disease burden and intervention effectiveness to project estimates of the long-term consequences of care. While models have been influential in informing US cancer screening guidelines under ideal conditions, incorporating detailed data on real-world screening practice has been limited given the complexity of screening processes and behaviors throughout diverse health delivery systems in the United States. The authors describe the synergies that exist between decision-analytic models and health care utilization…

The analysis of regulations affecting addictive or habitual goods has drawn considerable controversy. Some studies have suggested that such regulations have only small welfare benefits, as consumers value these goods despite health benefits from quitting, while other studies suggest that information or behavioral problems make existing consumption decisions a poor guide to welfare evaluation. This analysis examines potential utility offsets to health benefits of regulations affecting addictive or habitual goods theoretically and empirically. The paper…

ArticlePublication 2015A Conceptual Model for Breast, Cervical, and Colorectal Cancer Screening
General frameworks of the cancer screening process are available, but none directly compare the process …
General frameworks of the cancer screening process are available, but none directly compare the process in detail across different organ sites. This limits the ability of medical and public health professionals to develop and evaluate coordinated screening programs that apply resources and population management strategies available for one cancer site to other sites. This paper presents a conceptual model that incorporates a single screening episode for breast, cervical, and colorectal cancers into a unified framework based…

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 2013Contribution of H. Pylori and Smoking to US Incidence of Gastric Adenocarcinoma: A Microsimulation Model
Although gastric cancer has declined dramatically in the US, the disease remains the second leading …
Although gastric cancer has declined dramatically in the US, the disease remains the second leading cause of cancer mortality worldwide. This analysis estimates the contribution of risk factor trends on past and future intestinal-type non-cardia gastric adenocarcinoma (NCGA) incidence. The authors developed a population-based microsimulation model of intestinal-type NCGA and calibrated it to U.S. epidemiologic data on precancerous lesions and cancer. The model explicitly incorporated the impact of Helicobacter pylori and smoking on disease natural history, for which…
