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 Diagnosing HIV Infection During Early Infancy in South Africa
In this study the clinical impact and cost-effectiveness of four different early infant HIV diagnosis …
In this study the clinical impact and cost-effectiveness of four different early infant HIV diagnosis (EID) testing strategies for HIV-exposed infants in South Africa were compared using a microsimulation model. The strategies included (1) no EID (diagnosis only after illness), (2) and (3) testing once (at birth alone or at 6 weeks of age alone), and (4) testing twice (at birth and 6 weeks of age). Findings showed that the testing at birth alone strategy…

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…

ArticlePublication 2016Global Burden of Latent Tuberculosis Infection
Given the importance of controlling latent TB infection (LTBI) as part of the End TB …
Given the importance of controlling latent TB infection (LTBI) as part of the End TB Strategy for eliminating TB by 2050, the authors felt that changes in demography and scientific understanding, and progress in TB control, made it necessary to re-assess the global burden of LTBI. The authors used constructed trends in annual risk in infection to calculate the number and proportions of individuals infected, recently infected, and recently infected with isoniazid (INH)-resistant strains, aggregated…

ArticlePublication 2016Prevention of Hepatitis C by Screening and Treatment in U.S. Prisons
This study assesses the health and economic impact of hepatitis C virus (HCV) screening and …
This study assesses the health and economic impact of hepatitis C virus (HCV) screening and treatment in U.S. prisons on the broader HCV epidemic. Employing an agent-based microsimulation model of HCV transmission and disease progression, data from published literature inform the analysis. The target populations include individuals in U.S. prisons and the general community over a 30-year timeframe, adopting a societal perspective. Interventions encompass risk-based and universal opt-out HCV screening in prisons, followed by treatment…

ArticlePublication 2016Rotavirus Vaccines Contribute Towards UHC in A Mixed Public–Private Healthcare System
This extended cost-effectiveness analysis (ECEA) evaluates the non-health benefits of rotavirus vaccination in Malaysia from …
This extended cost-effectiveness analysis (ECEA) evaluates the non-health benefits of rotavirus vaccination in Malaysia from the household’s perspective. The authors found that rotavirus vaccination reduces rotavirus episodes and expenditure substantially and provides financial risk protection to all income groups. Although the rich are paying more out of pocket than the poor by utilizing more expensive healthcare, the poor are paying more in proportion to household income. Poverty reduction benefits are concentrated amongst the poorest two…

ArticlePublication 2016Departures from Cost-Effectiveness Recommendations: Health System Constraints
Cost-effectiveness analysis assumes a single constraint, in the form of the budget constraint, whereas in reality …
Cost-effectiveness analysis assumes a single constraint, in the form of the budget constraint, whereas in reality decision makers may be faced with numerous other constraints. The objective of this article is to develop a typology of constraints that may act as barriers to implementation of cost-effectiveness recommendations. Six categories of constraints are considered: the design of the health system; costs of implementing change; system interactions between interventions; uncertainty in estimates of costs and benefits; weak governance;…

ArticlePublication 2016Accounting for Technical, Ethical, and Political Factors in Priority Setting
This article investigates two cases of priority setting to explore how, in addition to technical …
This article investigates two cases of priority setting to explore how, in addition to technical considerations, ethical and political factors shape the allocation of health resources. First, they discuss how Thai authorities adjudicated a coverage decision for HLA-B*1502 screening, which meets the national cost-effectiveness threshold for only some of the conditions it can detect. Second, they consider England’s Cancer Drugs Fund to investigate the interplay of technical decision making and political reality. The findings suggest four concluding…

Cost-effectiveness analysis has traditionally been applied primarily to very specific interventions, such as drugs and …
Cost-effectiveness analysis has traditionally been applied primarily to very specific interventions, such as drugs and diagnostics; in addition, the evidence base drawn on for evaluating such interventions is relatively good, given the medical research industry surrounding their testing. However, with increasing success in controlling infectious diseases, many of the health challenges facing countries concern broad threats to health with multiple causes, such as obesity, where the relationship between policy action and health benefit is not…
