ArticlePublication 2022Comparison of Home Antigen Testing With RT-PCR and Viral Culture During the Course of SARS-CoV-2 Infection
As the availability of at-home self-collected antigen tests for SARS-CoV-2 increases, understanding their efficacy is …
As the availability of at-home self-collected antigen tests for SARS-CoV-2 increases, understanding their efficacy is crucial. A study in San Diego and Denver between January and May 2021 assessed the reliability of these tests against standard RT-PCR tests and viral cultures. Of the 225 participants with confirmed infections, the antigen test sensitivity was found to be 50% during the infectious period, 64% against the same-day RT-PCR, and 84% against the same-day cultures. Sensitivity was highest…

ReviewPublication 2022Diagnostics for COVID-19: Moving from Pandemic Response to Control
Diagnostics are essential in managing the COVID-19 pandemic, with three primary methods for detecting SARS-CoV-2 …
Diagnostics are essential in managing the COVID-19 pandemic, with three primary methods for detecting SARS-CoV-2 infections. Each test type remains vital as we shift from responding to controlling the pandemic. Molecular tests, like PCR, are highly precise in identifying viral RNA and are endorsed by the WHO for confirming cases and guiding public health actions. Antigen rapid tests spot viral proteins and, while less accurate than molecular tests, are quicker, more affordable, simpler, and can…

ArticlePublication 2023Single-Arm Trial Design Estimates Efficacy
Studies to confirm the efficacy of a single HPV vaccine dose, of vaccine durability, and …
Studies to confirm the efficacy of a single HPV vaccine dose, of vaccine durability, and of vaccination modifications are needed, but randomized controlled trials are costly and face logistical and ethical challenges. In this study, the authors demonstrate proof-of-principle that a single-arm design yields valid estimates with similar precision to a randomized controlled trial.

ArticlePublication 2023Effects of Public Financing of Essential Maternal and Child Health Interventions Across Wealth Quintiles in Nigeria: An Extended Cost-Effectiveness Analysis
This study evaluates the potential health and financial risk protection benefits of public financing for …
This study evaluates the potential health and financial risk protection benefits of public financing for maternal, newborn, and child health (MNCH) interventions in Nigeria, focusing on different wealth quintiles. Employing extended cost-effectiveness analysis, the research assesses the impact of a policy ensuring zero out-of-pocket costs for 18 essential MNCH services. Three scenarios were modeled: status quo, uniform scale-up, and pro-poor scale-up. Findings suggest that a 5% increase in coverage for all quintiles could prevent significant…

ArticlePublication 2022Potential Distributional Health & Financial Benefits of Increased Tobacco Taxes in Ethiopia: Findings from a Modeling Study
This study evaluates the potential impacts of Ethiopia's tobacco tax increase in 2020, which raised …
This study evaluates the potential impacts of Ethiopia's tobacco tax increase in 2020, which raised cigarette prices by approximately 67%. Employing parameters such as price elasticity of demand and smoking prevalence, the analysis utilizes existing literature and secondary data to model the effects of the reform on various outcomes, focusing on life years, tax revenues, cigarette expenditures, and catastrophic health expenditures (CHE). Concentrating solely on male smokers due to low female smoking rates, the results…

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 2021Distributional Health and Financial Consequences of Increased Cigarette Tax in Iran: An ECEA
This study examines the potential impact of a tax-induced cigarette price increase on financial and …
This study examines the potential impact of a tax-induced cigarette price increase on financial and health outcomes across different socioeconomic groups in Iran. Using pooled cross-sectional data from Household Income and Expenditure Surveys (2002–2017) and population data from Iran in 2019, an extended cost-effectiveness analysis (ECEA) methodology is employed to model the effects of a hypothetical increase in cigarette tax. The analysis evaluates health benefits, health expenditures averted, additional tax revenues generated, changes in household…

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…

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…
