ArticleWeb Portal 2017PLOS Collection: Economic Efficiency of HIV Services
In order to maximize the value for money for HIV services and increase efficiency without …
In order to maximize the value for money for HIV services and increase efficiency without sacrificing quality, robust and up-to-date data on costs, efficiency and its determinants are needed. This PLOS collection, Economic Efficiency of HIV Services, presents recent, high-quality evidence from low- and middle-income countries on costs and technical efficiency of HIV services and their determinants. These data contribute to the current discussion on optimizing resources for HIV services and can provide programmatic guidance for…

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 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 2017When Cost-Effective Interventions Are Unaffordable
Many health interventions deemed cost-effective are not affordable. Despite the importance of affordability to policymakers, …
Many health interventions deemed cost-effective are not affordable. Despite the importance of affordability to policymakers, little of the cost-effectiveness literature in global health addresses this issue. Budget impact analysis (BIA) describes an intervention's short-term costs and savings from the payer's perspective. This paper assesses the current use of budget impact analysis (BIA) and cost-effectiveness analysis (CEA) in health economic assessments conducted for low- and middle-income countries (LMICs). The authors recommend steps researchers and policymakers can…

Tutorial/PrimerPublication, Teaching Resource 2017Bayesian Methods for Calibrating Health Policy Models: A Tutorial
This article provides a tutorial on Bayesian approaches for model calibration. It describes the theoretical …
This article provides a tutorial on Bayesian approaches for model calibration. It describes the theoretical basis for Bayesian calibration approaches as well as pragmatic considerations that arise in the tasks of creating calibration targets, estimating the posterior distribution, and obtaining results to inform the policy decision. These considerations, as well as the specific steps for implementing the calibration, are described in the context of an extended worked example about the policy choice to provide (or…

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 2017Policy Makers, the International Community and the Population: Case Study on HIV/AIDS
A four-period game is developed between a policy maker, the international community, and the population. …
A four-period game is developed between a policy maker, the international community, and the population. This research supplements, through implementing strategic interaction, earlier research analyzing "one player at a time." The first two players distribute funds between preventing and treating diseases. The population reacts by degree of risky behavior which may cause no disease, disease contraction, recovery, sickness/death. More funds to prevention implies less disease contraction but higher death rate given disease contraction. The cost…

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…
