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…

Resource PackPublication, Teaching Resource 2020Resource Pack: Cost-Effectiveness of SSB Excise Taxes
The use of fiscal instruments, such as taxes or subsidies, to promote healthier dietary behavior …
The use of fiscal instruments, such as taxes or subsidies, to promote healthier dietary behavior has been of increasing interest in the last decade as the evidence-base builds for the health and economic consequences of obesity, overweight, and unhealthy eating. The motivation for using fiscal instruments in nutrition policy is to make the unhealthy option less affordable and less economically attractive by increasing the price via a tax, and therefore reduce the incentive to consume…

ArticlePublication 2020Weighing Evidence to Inform Clinical Decisions

The authors use a clinical example to simulate how treatment discussions can be complicated when new evidence is introduced that conflicts with existing guidelines. Even when evidence is consistent, the authors point out that current guidelines can have interpretations that don't agree with available evidence. They develop a step-wise algorithm to help guide individual clinical decisions even in the absence of general consensus related to appropriate testing and treatment.

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…

Resource PackPublication, Teaching Resource 2021Resource Pack: Valuing Health and Longevity in BCA
This resource pack, curated by the Center for Health Decision Science, introduces the valuation of …
This resource pack, curated by the Center for Health Decision Science, introduces the valuation of changes in health and longevity in benefit-cost analysis. It is targeted towards advanced students and practitioners who have a basic understanding of the benefit-cost analysis framework, as discussed in the Resource Pack: Introduction to Benefit-Cost Analysis. That pack provides a general overview of the approaches that are explored in more detail here, as well as related guidance documents. This pack…

Online LearningVideo, Teaching Resource 2020Valuing Statistical Lives: Concepts, Current Practices, and Challenges
Many policies aim to improve longevity, decreasing the risk of death in each year, and …
Many policies aim to improve longevity, decreasing the risk of death in each year, and the value of these risk reductions often dominate the estimated benefits of risk regulations and other policies. This value is often expressed as the value per statistical life (VSL), a term that is widely misunderstood. It is not the value that the analyst, the government, or the individual places on saving an identified life with certainty. Instead, it reflects individuals’…

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 2017Extended Cost-Effectiveness Analyses of Cardiovascular Risk Factor Reduction Policies
This chapter summarizes lessons learned from three extended cost-effectiveness analyses (ECEAs) conducted on cardiovascular disease …
This chapter summarizes lessons learned from three extended cost-effectiveness analyses (ECEAs) conducted on cardiovascular disease (CVD) risk factor reduction policies, specifically highlighting new insights into the differential impacts of well-established CVD prevention interventions. Tobacco taxation, salt reduction, and primary prevention of CVD in high-risk individuals remain widely regarded as best buys in global noncommunicable disease policy, and the ECEAs confirm the findings of previous CEAs, namely, that these interventions will likely result in large health…

This country profile on Afghanistan is published by the United Nations Development Programme (UNDP). Each online country profile also links to a downloadable data table and a briefing note for its country. The Human Development Report Office releases data each year, including the Human Development Index (HDI), the Inequality-Adjusted Human Development Index (IHDI), the Gender Development Index (GDI), the Gender Inequality Index (GII), and the Multidimensional Poverty Index (MPI). These indices reflect the UNDP human…
