This analysis was motivated by the South African Department of Health's request to assess the cost implications of adopting sets of ART guidelines issued by the World Health Organization between 2010 and 2016.Using data from large South African ART clinics (n = 24,244 patients), projections of patients in need of ART, and cost data from bottom-up cost analyses, the authors constructed a population-level health-state transition model with 6-monthly transitions between health states depending on patients’ age,…

ArticlePublication 2017Benefit and Harm of Intensive Blood Pressure Treatment: Derivation and Validation of Risk Models Using Data from the Sprint and Accord Trials
Intensive blood pressure (BP) treatment can avert cardiovascular disease (CVD) events but can cause some …
Intensive blood pressure (BP) treatment can avert cardiovascular disease (CVD) events but can cause some serious adverse events. The authors sought to create risk calculators to estimate individual patients’ chances of benefit and harm from intensive treatment. They developed statistical models of cardiovascular events and serious adverse events from individual participant data from the Systolic Blood Pressure Intervention Trial (SPRINT) of intensive blood pressure treatment (N = 9,069 with complete covariate data) and validated them…

ReviewPublication 2017Model-Based Economic Evaluation of Treatments for Depression: A Systematic Review
This article, published in Pharmacoeconomics, systematically reviews the literature in order to identify model-based studies …
This article, published in Pharmacoeconomics, systematically reviews the literature in order to identify model-based studies evaluating the cost-effectiveness of treatments for depression and examine the appropriateness of different modelling technique for simulating the natural course of depression. The review yielded 41 model-based studies, of which 21 used decision trees (DTs), 15 used cohort-based state-transition Markov models (CMMs), two used individual-based state-transition models (ISMs), and three used discrete-event simulation (DES) models. Just over half of the…

Tools/ModelsPublication, Teaching Resource 2017Publicly Available Software Tools for Decision-Makers During an Emergent Epidemic
Epidemics and emerging infectious diseases are becoming an increasing threat to global populations-challenging public health …
Epidemics and emerging infectious diseases are becoming an increasing threat to global populations-challenging public health practitioners, decision makers and researchers to plan, prepare, identify and respond to outbreaks in near real-timeframes. The aim of this research is to evaluate the range of public domain and freely available software epidemic modelling tools. Twenty freely utilizable software tools underwent assessment of software usability, utility and key functionalities. Stochastic and agent based tools were found to be highly…

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 Routine Vaccination With a Live-Attenuated Dengue Vaccine: Model Comparison
Large Phase III trials across Asia and Latin America have demonstrated the efficacy of a recombinant, …
Large Phase III trials across Asia and Latin America have demonstrated the efficacy of a recombinant, live-attenuated dengue vaccine (Dengvaxia) over the first 25 months following vaccination. Subsequent data collected in the longer-term follow-up phase, however, have raised concerns about a potential increase in hospitalization risk of subsequent dengue infections, in particular among young, dengue-naïve vaccinees. This paper reports predictions from eight independent modelling groups on the long-term safety, public health impact, and cost-effectiveness of routine…

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…

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 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…
