ArticlePublication 2017Using Data-Driven Agent-Based Models to Forecast Emerging Infectious Diseases
This paper describes an agent-based model framework developed to forecast the 2014-15 Ebola epidemic, which …
This paper describes an agent-based model framework developed to forecast the 2014-15 Ebola epidemic, which was subsequently used in the Ebola forecasting challenge. Producing timely and reliable forecasts for an epidemic of an emerging infectious disease is a challenge. Epidemiologists and policy makers have to deal with poor data quality, limited understanding of the disease dynamics, a rapidly changing social environment and the uncertainty around the effects of various interventions in place. In this setting,…

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 2016Cost-Effectiveness of Collaborative Care for Depression and Comorbid Diabetes or CVD
This article, published in BMJ Open, presents an economic model that combines a decision tree …
This article, published in BMJ Open, presents an economic model that combines a decision tree and a Markov cohort model to investigate the long-term cost-effectiveness of collaborative care versus usual care for individuals with depression and comorbid diabetes and/or cardiovascular disease. Data from the COINCIDE trial informs the model input parameters. The COINCIDE trial is a randomized controlled trial of collaborative care versus usual care that enrolled 387 participants from 36 primary care general practices…

ArticlePublication 2016An Economic Evaluation of the PEN Program in Indonesia
Responding to the economic and health burden of noncommunicable diseases (NCDs), the World Health Organization (WHO) …
Responding to the economic and health burden of noncommunicable diseases (NCDs), the World Health Organization (WHO) introduced the Package of Essential Noncommunicable disease (PEN) interventions. Several countries, including Indonesia, implemented the PEN program. To assess the value of the investment in the current program, an economic evaluation of the program was conducted with collaboration between the Ministry of Health in Indonesia, the WHO, and the International Decision Support Initiative (iDSI). This study evaluated the delivery of…

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…

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 2014Cost-Effectiveness of Female HPV Vaccination in 179 Countries: A PRIME Modelling Study
The authors present a simple generic model, Papillomavirus Rapid Interface for Modelling and Economics (PRIME), …
The authors present a simple generic model, Papillomavirus Rapid Interface for Modelling and Economics (PRIME), used to assess cost-effectiveness and health effects of vaccination of girls against HPV before sexual debut in terms of burden of cervical cancer and mortality. The PRIME models incidence according to proposed vaccine efficacy against HPV 16/18, vaccine coverage, cervical cancer incidence and mortality, and HPV type distribution. It assumes lifelong vaccine protection and no changes to other screening programs…

ArticlePublication 2014Cost-Effectiveness of Second-Generation Antipsychotics for the Treatment of Schizophrenia
This article, published in Value in Health, describes a Markov model that compares the cost-effectiveness …
This article, published in Value in Health, describes a Markov model that compares the cost-effectiveness of alternate sequences of treatment strategies using second-generation antipsychotics (SGAs) for patients with schizophrenia. First-line treatments include one of the four SGAs: olanzapine (OLZ), risperidone (RSP), quetiapine (QTP), and ziprasidone (ZSD). Patients are able switch to another of these antipsychotics as second-line therapy, and only clozapine (CLZ) is allowed as third-line treatment. Model input parameters were obtained from the Clinical…
