ArticlePublication 2022Re-Evaluating the Health Impact and Cost-Effectiveness of Tuberculosis Prevention for Modern ART Cohorts
TB preventive therapy (TPT) is widely accepted to be cost-effective for reducing TB incidence in …
TB preventive therapy (TPT) is widely accepted to be cost-effective for reducing TB incidence in HIV-infected individuals receiving antiretroviral therapy (ART). However, as individuals initiate ART earlier in the course of disease, TB incidence is lower, and it is unclear how ART cost-effectiveness has changed. This study assessed the cost-effectiveness of TPT in contemporary ART cohorts. The authors developed a microsimulation model of TB and HIV and parameterised it using data from a large HIV…

ArticlePublication 2022Comparing Health Gains, Costs & Cost-Effectiveness of Interventions in Australia & New Zealand
This paper synthesizes the health gains, costs, and cost-effectiveness of health interventions in Australia and New …
This paper synthesizes the health gains, costs, and cost-effectiveness of health interventions in Australia and New Zealand (NZ) from studies conducted with comparable methods, and reports results in the form of an online interactive league table. Studies from the Australia Cost-Effectiveness research and NZ Burden of Disease Epidemiology, Equity and Cost-Effectiveness Programmes and studies were included which reported health-adjusted life years (HALYs) and net health system costs and/or incremental cost-effectiveness ratios, used a time horizon of…

ArticlePublication 2022Cost-Effectiveness & Value-of-Information Analysis Using Machine Learning-Based Metamodeling: A Case of Hepatitis C Treatment
This study compares machine learning (ML)-based metamodels with conventional metamodeling approaches in replicating the outcomes …
This study compares machine learning (ML)-based metamodels with conventional metamodeling approaches in replicating the outcomes of a complex simulation model of hepatitis C virus (HCV) natural history. Three ML-based metamodels (random forest, support vector regression, and artificial neural networks) and a linear regression-based metamodel were developed from the simulation model's 40 input parameters. Performance evaluation included root mean squared error (RMSE) and Pearson's R2 on normalized data. ML-based metamodels generally outperformed linear regression, with random…

ArticlePublication 2022Child Health Inequity through Case Management of Under-Five Malaria in Nigeria: An ECEA
This study assesses the potential impact of subsidies covering the direct and indirect costs of …
This study assesses the potential impact of subsidies covering the direct and indirect costs of under-five malaria case management in Nigeria, utilizing an extended cost-effectiveness analysis (ECEA) and a decision tree model. Findings reveal that fully subsidizing medical, non-medical, and indirect costs could annually avert over 19,000 under-five deaths, 8,600 cases of catastrophic health expenditure (CHE), and US$187 million in out-of-pocket (OOP) spending. Per US$1 million invested, this translates to a significant reduction in under-five…

ArticlePublication 2020Testing for SARS-CoV-2 Antibodies
Antibody testing can determine previous exposure to SARS-CoV-2 virus. Recently, the UK government has made …
Antibody testing can determine previous exposure to SARS-CoV-2 virus. Recently, the UK government has made antibody testing available to anyone wanting it, even if there is no clinical indication. The purpose of this article is to provide guidance for when to consider antibody testing in individuals with and without symptoms suggestive of current or past SARS-CoV-2 infection. Key points made by the authors include: (1) antibody testing is likely to be most useful 2 weeks…

ArticlePublication 2020Health Gains & Financial Risk Protection Afforded by Public Financing of Selected Malaria Interventions in Ethiopia: An ECEA
This article, published in the Malaria Journal, aims to estimate the expected health and financial …
This article, published in the Malaria Journal, aims to estimate the expected health and financial risk protection (FRP) benefits of universal public financing of key malaria interventions in Ethiopia. An extended cost-effectiveness analysis (ECEA) is used to estimate the potential health and FRP benefits of publicly financing a 10% increase in artemisinin-based combination therapy (ACT), long-lasting insecticide-treated bed nets (LLIN), indoor residual spraying (IRS), and a hypothetical malaria vaccine. The results indicate that ACT, LLIN,…

ArticlePublication 2019Spatial Distribution and Characteristics of HIV
This article, published in Tropical Medicine & International Health, aims to identify the spatial and …
This article, published in Tropical Medicine & International Health, aims to identify the spatial and temporal trends, and epidemiologic correlates, of HIV clusters in Ethiopia. The authors use biomarker and survey data from the 2005, 2011, and 2016 Ethiopia Demographic and Health Surveys (DHS), and the spatial-temporal distribution of HIV is estimated using the Kulldorff spatial scan statistic, a likelihood-based method for determining clustering. The study results indicate that in Ethiopia, geographic HIV clusters are…

ArticlePublication 2019Systematic Review of Economic Evaluations of Vaccination Strategies Against Tuberculosis
Bacillus Calmette-Guérin (BCG) is the only licensed vaccine for tuberculosis, but its effectiveness is limited …
Bacillus Calmette-Guérin (BCG) is the only licensed vaccine for tuberculosis, but its effectiveness is limited and varies by age, so a valid cost-effectiveness study is needed to assist decision-makers in the implementation of cost-effective strategies for BCG vaccination. Using the Quality of Health Economic Studies (QHES) instrument, the authors assessed the quality of published studies involving economic evaluations of BCG vaccination strategies in a variety of regions, target populations, and vaccine types. Most of the…

ArticlePublication 2019Decision-Making for Universal Access to Tuberculosis Diagnosis In India
The authors evaluated the costs of centralized and decentralized testing for tuberculosis with Xpert MTB/RIF …
The authors evaluated the costs of centralized and decentralized testing for tuberculosis with Xpert MTB/RIF (Xpert), a WHO-endorsed test. They used an agent-based simulation of TB transmission in a hypothetical representative region in India to assess the impact and cost-effectiveness of various strategies to provide universal access to diagnosis and drug susceptibility testing (DST) for tuberculosis. The authors found that decentralization was most favorable compared to centralized testing when volume at decentralized facilities was high,…
