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 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…

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 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 2020Premature Deaths, Statistical Lives, and Years of Life
This article clarifies some misconceptions about mortality risk and economic valuation. The mortality effects of …
This article clarifies some misconceptions about mortality risk and economic valuation. The mortality effects of exposure to environmental hazards such as air pollution are often described by the estimated number of “premature deaths” and the economic value of an exposure reduction as the number of “statistical lives saved” multiplied by the “value per statistical life.” These terms can be misleading because the number of deaths advanced by exposure cannot be determined from mortality data; it…

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 2018Comparing Cost-per-QALYs Gained to Cost-per-DALYs Averted
The authors examined 6,438 cost-per-QALY and 543 cost-per-DALY studies published through 2016 using two databases, …
The authors examined 6,438 cost-per-QALY and 543 cost-per-DALY studies published through 2016 using two databases, the Tufts Medical Center CEA Registry (cost-per-QALY gained studies), and the Global Cost-Effectiveness Analysis (GHCEA) Registry (cost-per-DALY averted studies). Study characteristics that were analyzed included intervention type, sponsor, country, primary disease, and number of CEAs versus disease burden estimates for major conditions. The authors report that cost-per-QALY studies were most often about pharmaceuticals or interventions in high-income countries while cost-per-DALY…

ReviewPublication 2018Equity Considerations in CEA: Rotavirus Vaccine in LMIC's
The authors used a systematic review of the literature to identify economic evaluations of rotavirus …
The authors used a systematic review of the literature to identify economic evaluations of rotavirus vaccine in LMICs and assess the extent to which equity was considered in the objectives, analysis, and results. They used equity-related indicators provided in the Guidance on Priority Setting in Health Care (GPS-Health) checklist criteria resulting in 18 unique indicators tracked. The authors found that some articles incorporated the indicators in their model inputs (20%) while the majority (80%) presented…
