EditorialPublication 2020Waiting for Certainty on COVID-19 Antibody Tests — At What Cost?
This perspective anticipates the availability of serologic antibody testing and considers its potential usefulness in mitigation …
This perspective anticipates the availability of serologic antibody testing and considers its potential usefulness in mitigation policy to reduce COVID-19 transmission. For example: Could we screen for serologic antibodies as a proxy for possible immunity and identify people who could return to the workplace with less severe mitigation measures? The authors acknowledge the uncertainties raised by many policy actors, including the WHO, such as, "Do antibodies confer immunity and, if so, for how long? How accurate is…

ArticlePublication 2020Economic Evaluation of HBV Birth Dose Vaccination
This article, published in Cost Effectiveness and Resource Allocation, examines the cost-effectiveness of a birth …
This article, published in Cost Effectiveness and Resource Allocation, examines the cost-effectiveness of a birth dose of HBV vaccine in a medical setting in Ethiopia. The authors construct a decision analytic model with a Markov process to estimate the costs and effects of a birth dose of HBV vaccine, compared with current practices in Ethiopia. Based on the cost-effectiveness findings, introducing a birth dose of HBV vaccine in Ethiopia would likely be highly cost-effective. Such…

ArticlePublication 2020New Fronts in the War on Misinformation
The countless false claims that have spread alongside the novel coronavirus – inaccurate advice about …
The countless false claims that have spread alongside the novel coronavirus – inaccurate advice about how to prevent the virus, for example, and conspiracy theories about its origins – are just the latest manifestation of an ongoing problem: the online proliferation of misinformation about science and health. The National Academies hosted and helped organize three events focused on countering misinformation: The MisinfoCon conference, a Wikipedia Edit-a-thon, and a meeting to explore ways to expand successful…

ArticlePublication 2020Bayes' Theorem, COVID-19, and Screening Tests
This article reviews the implications of increased testing for COVID-19 using reverse transcriptase polymerase chain …
This article reviews the implications of increased testing for COVID-19 using reverse transcriptase polymerase chain reaction (rRT-PCR) through the application of Bayes’ Theorem for three hypothetical, stylized case scenarios. The scenarios involve three patients with a low, moderate, and high pre-test probability of COVID-19 infection. The category of low probability would include "asymptomatic individuals in a presumed low prevalence environment" and might vary from 10 to 20%. The category of moderate probability would include "individuals…

ArticlePublication 2020Interpreting COVID-19 Test Results: A Bayesian Approach
This article considers the following question with respect to interpreting the results of polymerase chain reaction …
This article considers the following question with respect to interpreting the results of polymerase chain reaction (PCR) assays from nasal and pharyngeal swabs for COVID-19 to inform clinical decision making: "While a positive result in an acutely ill patient is straightforward, how should physicians interpret negative tests in patients with suspected COVID-19 infection?" Using an assumption of near-perfect specificity of PCR assays for COVID-19, the authors acknowledge the uncertainty of test sensitivity. They consider two clinical scenarios…

ArticlePublication 2020Financial Burden of HIV and TB
This article, published in BMJ Open, aims to estimate the household economic burden and incidence …
This article, published in BMJ Open, aims to estimate the household economic burden and incidence of catastrophic health expenditures (CHE) incurred as a result of HIV and TB care across income quintiles in Ethiopia. The economic burden of HIV and TB care is estimated looking at direct and indirect costs, whereas the incidence of CHE is determined using direct costs that exceed 10% of the household income threshold. HIV and TB are found to cause…

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 2017Catastrophic Costs Potentially Averted by TB Control in India and South Africa
This study estimated the reduction in tuberculosis-related catastrophic costs with an aggressive expansion of tuberculosis …
This study estimated the reduction in tuberculosis-related catastrophic costs with an aggressive expansion of tuberculosis services in India and South Africa from 2016 to 2035, in line with the End TB Strategy. The authors investigated three intervention scenarios: improved treatment of drug-sensitive tuberculosis; improved treatment of multidrug-resistant tuberculosis; and expansion of access to tuberculosis care through intensified case finding (South Africa only). In India and South Africa, improvements in treatment for drug-sensitive and multidrug-resistant tuberculosis…

ArticlePublication 2019Health and Financial Benefits of Averting Malaria in Zambia: An ECEA
This study used the extended cost-effectiveness analysis (ECEA) to examine impact of the hypothetical rollout …
This study used the extended cost-effectiveness analysis (ECEA) to examine impact of the hypothetical rollout of the malaria vaccine RTS,S/AS01 in Zambia on the health benefits of children under five, and financial benefits on their households. The authors assumed a three-dose vaccination schedule (over 6-9 months), and vaccine cost of US$5 per dose. To assess vaccine impact, for each income quintile, they computed the number of under-five malaria deaths prevented, the household out-of-pocket (OOP) malaria-related…
