ArticlePublication 2017Estimating the Fitness Cost and Benefit of Cefixime Resistance in Neisseria Gonorrhoeae
Gonorrhoea is one of the most common bacterial sexually transmitted infections in England, and more …
Gonorrhoea is one of the most common bacterial sexually transmitted infections in England, and more than half of annual infections occur in men who have sex with men (MSM). As the bacterium has developed resistance to each first-line antibiotic in turn, an improved understanding is needed of fitness benefits and costs of antibiotic resistance to inform control policy and planning. The authors developed a stochastic compartmental model representing the natural history and transmission of cefixime-sensitive…

ArticlePublication 2017Changing the South African National ART Guidelines: The Role of Cost Modelling
This analysis was motivated by the South African Department of Health's request to assess the …
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 2017Getting it Right When Budgets are Tight: Prioritizing Responses to HIV Epidemics
Prioritizing investments across health interventions is complicated by the nonlinear relationship between intervention coverage and …
Prioritizing investments across health interventions is complicated by the nonlinear relationship between intervention coverage and epidemiological outcomes. It can be difficult for countries to know which interventions to prioritize for greatest epidemiological impact, particularly when budgets are uncertain.The authors examined four case studies of HIV epidemics in diverse settings, each with different characteristics. These case studies were based on public data available for Belarus, Peru, Togo, and Myanmar. The Optima HIV model and software package…

ArticlePublication 2017Predicting Carer Health Effects for Use in Economic Evaluation
Illnesses and interventions can affect the health status of family carers in addition to patients. …
Illnesses and interventions can affect the health status of family carers in addition to patients. However economic evaluation studies rarely incorporate data on health status of carers. In order to investigate whether changes in carer health status could be ‘predicted’ from the health data of those they provide care to, as a means of incorporating carer outcomes in economic evaluation, the authors used regression models to analyse changes in carers’ health status. They derive predictive algorithms based on…

ArticlePublication 2017Estimated Economic Impact of Vaccinations in 73 LMIC, 2001-2020
This analysis estimates the economic impact likely to be achieved by efforts to vaccinate against 10 …
This analysis estimates the economic impact likely to be achieved by efforts to vaccinate against 10 vaccine-preventable diseases between 2001 and 2020 in 73 low- and middle-income countries largely supported by Gavi, the Vaccine Alliance. The authors used health impact models to estimate the economic impact of achieving forecasted coverages for vaccination against Haemophilus influenzae type b, hepatitis B, human papillomavirus, Japanese encephalitis, measles, Neisseria meningitidis serogroup A, rotavirus, rubella, Streptococcus pneumoniae and yellow fever. In…

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 2017Designing an Optimal HIV Programme for South Africa
This 2017 study compares the traditional and a novel method of comparing cost-effectiveness interventions in …
This 2017 study compares the traditional and a novel method of comparing cost-effectiveness interventions in the context of HIV in South Africa, using a modeling approach. The authors argue that the assumptions of a) independence of interventions, and b) linear scale-up effects do not hold because South Africa has a large domestically funded HIV program with highly saturated coverage levels. The authors therefore aim to better allocate resources for HIV interventions in South Africa when…

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…
