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 2019Cost-Effectiveness of Community-Based Childhood Obesity Prevention Interventions in Australia
This study examined the cost-effectiveness of community-based obesity prevention interventions (CBIs) consisting of strategies to …
This study examined the cost-effectiveness of community-based obesity prevention interventions (CBIs) consisting of strategies to promote healthy eating and physical activity for Australian children aged between 5-18 years. A multiple cohort Markov model that simulates diseases associated with overweight and obesity was used to estimate the health benefits, measured as health-adjusted life years (HALYs) and healthcare-related cost offsets from diseases averted due to exposure to the intervention. Health and cost outcomes were estimated over the…

ArticlePublication 2020Translating Population Evidence to Individual Patients
In this paper, the authors describe the differences in population level outcomes compared to individual …
In this paper, the authors describe the differences in population level outcomes compared to individual patients and discuss ways that these are differences. The authors cover topics including the difference between relative and absolute risk and benefit. They use an example of the decision to start anticoagulation in new-onset atrial fibrillation to discuss translating population level evidence to treatment of an individual. These options include generalizability, subgroup analysis, prediction rules, following response to therapy, and even…

ArticlePublication 2020Clinical Decision Making: Using a Diagnostic Test
This article is part of a 6-part series on clinical decision making. The authors use …
This article is part of a 6-part series on clinical decision making. The authors use two clinical examples to review the principles of interpreting diagnostic test results. They outline an approach that can be used to determine how to select and apply tests and their results to the practice of internal medicine. Topics covered in the two case studies include sensitivity and specificity, positive predictive and negative predictive value of tests, and how to estimate…

ArticlePublication 2020Equity & Distributional Impact on Stunting of a Nutritional Package, Children Aged 6-36 Months in China: Modeling Study Findings
This article evaluates the potential impact of rolling out the Ying Yang Bao (YYB) nutritional …
This article evaluates the potential impact of rolling out the Ying Yang Bao (YYB) nutritional package on child stunting across provinces and wealth groups in China, focusing on equity. Utilizing data from the China Family Panel Studies and extended cost-effectiveness analysis methods, the study estimates the distributional impact of a 12-month YYB program for children aged 6-36 months across 25 provinces and two wealth groups. Results indicate that a 75% coverage of YYB could avert…

ArticlePublication 2018Consequences of a Cigarette Price Increase in 13 Middle Income Countries
This study used extended cost-effectiveness analysis to examine the impact of a 50% increase in …
This study used extended cost-effectiveness analysis to examine the impact of a 50% increase in market prices of cigarettes on health, poverty, and financial protection for men in 13 middle income countries. A 50% increase in cigarette prices would lead to about 450 million years of life gained across the 13 countries from smoking cessation, with half of these in China. Across all countries, men in the bottom income group would gain 6.7 times more…

ArticlePublication 2017Distributional Benefits of Tobacco Tax and Smoke-Free Workplaces in China
This study used the extended cost–effectiveness analysis (ECEA) to evaluate, across income quintiles of the …
This study used the extended cost–effectiveness analysis (ECEA) to evaluate, across income quintiles of the male population, the premature deaths averted, the change in tax revenues generated, and the financial risk protection procured, that would follow a 75% increase in cigarette prices through substantial increments in excise tax fully passed onto consumers, and a nationwide total implementation of workplace smoking bans. A 75% increase in cigarette prices would avert about 24 million premature deaths among…

ArticlePublication 2015Consequences of Tobacco Tax in Rich and Poor Smokers in China: An ECEA
This study used the extended cost-effectiveness analysis methods to estimate, across income quintiles of the …
This study used the extended cost-effectiveness analysis methods to estimate, across income quintiles of the male population, the health benefits (years of life gained), the additional tax revenues raised, the net financial consequences for households, and the financial risk protection provided to households, that would be caused by a 50% increase in tobacco price through excise tax fully passed onto tobacco consumers in China. The analysis showed that a 50% increase in tobacco price through…

ArticlePublication 2013Agent-Based Simulation Modelling Approach to ECEA of Health Interventions
This study develops a dynamic agent-based simulation model, the Disease Control Priorities Simulation (DCPSim) model, …
This study develops a dynamic agent-based simulation model, the Disease Control Priorities Simulation (DCPSim) model, to estimate the health and economic benefits of health interventions and policies. Authors examined two different policies that can scale up the availability of drugs for secondary prevention of acute myocardial infarction (AMI) in India: a universal public provision (UPP) that provides a drug for free at public health facilities, and a universal public finance (UPF) that provides a drug…
