ArticleWeb Portal 2017PLoS Collection: Prevention, Diagnosis and Treatment of Sexually Transmitted Infections
Globally, the World Health Organization (WHO) estimates that more than one million new sexually transmitted …
Globally, the World Health Organization (WHO) estimates that more than one million new sexually transmitted infections (STIs) occur each day, incurring a very substantial burden of morbidity, mortality and additional infections. The pathogens responsible include bacteria, parasites and viruses, and intensive research is needed to address the substantial barriers to diagnosis and treatment of STIs, and the behavioral challenges of prevention. This PLOS collection, published in collaboration with WHO, focuses on global policy and systems…

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 2017Revealed Willingness-to-Pay vs. Standard Cost-Effectiveness Thresholds
This study estimates the cost-effectiveness thresholds (CETs) of 16 HIV programs in South Africa. The …
This study estimates the cost-effectiveness thresholds (CETs) of 16 HIV programs in South Africa. The use of CETs based on a country’s income per capita has been criticized for not being grounded in theory or evidence, especially in low and middle-income countries (LMICs). An alternative has been produced for South Africa, based on estimates of life years saved and the country’s committed HIV budget. The authors used a previously -published optimization method to estimate CETs,…

ArticlePublication 2017Cost-Effectiveness of Testing and Treatment for Latent TB
Testing for and treating latent tuberculosis infection (LTBI) is among the main strategies to achieve …
Testing for and treating latent tuberculosis infection (LTBI) is among the main strategies to achieve TB elimination in the United States. This analysis estimated health outcomes, costs, and cost-effectiveness of LTBI testing and treatment among non-US born residents with and without medical comorbidities (e.g., diabetes, HIV infection, and end-stage renal disease). A decision analytic tree and Markov cohort simulation model was used to compare the following strategies: no testing, tuberculin skin test (TST), interferon gamma release assay…

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 2017Valuing Non-Fatal Risks: Monetary and Health-Utility Measures
This article discusses metrics for valuing environmental, health, and safety policies, which should be consistent …
This article discusses metrics for valuing environmental, health, and safety policies, which should be consistent with both the preferences of affected individuals and social preferences for distribution of health risks in the population. Two classes of metrics are widely used: monetary measures (e.g., willingness to pay) and health-utility measures (e.g., quality-adjusted life years (QALYs), disability-adjusted life years (DALYs)). Health-utility measures impose more structure than monetary measures, with the result that individuals’ preferences often appear inconsistent…

This article serves as a guide to using cost-effectiveness analysis (CEA) to address health equity …
This article serves as a guide to using cost-effectiveness analysis (CEA) to address health equity concerns. The authors introduce the "equity impact plane," a tool for considering trade-offs between improving total health-the objective underpinning conventional CEA-and equity objectives, such as reducing social inequality in health or prioritizing the severely ill. Improving total health may clash with reducing social inequality in health, for example, when effective delivery of services to disadvantaged communities requires additional costs. Who…

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,…
