Tools/ModelsInteractive, Teaching Resource 2020Interactive Graphic: Interpreting a COVID-19 Test Result
Currently, the most common diagnostic test for COVID-19 relies on reverse transcriptase polymerase chain reaction …
Currently, the most common diagnostic test for COVID-19 relies on reverse transcriptase polymerase chain reaction (RT-PCR), and most often uses samples obtained from the respiratory tract by nasopharyngeal swab. This interactive graphic demonstrates the influence of the prior probability of COVID-19, the test sensitivity (i.e., the probability of a positive test conditional on disease presence), and the test specificity (i.e., the probability of a negative test conditional on disease absence) on the post-test probability of…

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 2020Incorporating Perspective into Clinical Decisions
Part of a six-part series of articles on clinical decision making, in this article, the …
Part of a six-part series of articles on clinical decision making, in this article, the authors discuss how to incorporate perspective into clinical decisions, explicitly acknowledging that the treating physician is not the only stakeholder in these decisions. The authors use 2 case studies to demonstrate how changes in perspective can alter the clinical decision as well lead to both intended and unintended consequences to the outcomes.

Resource PackPublication, Teaching Resource 2022Resource Pack: Decision Analysis & Childhood Obesity
This resource pack on childhood obesity was curated by the Center for Health Decision Science …
This resource pack on childhood obesity was curated by the Center for Health Decision Science to showcase existing cost-effectiveness analyses and motivate students, educators, and others to pursue new applications of decision science methods to the public health challenge of obesity. The resource pack was motivated by the NEJM article entitled Simulation of Growth Trajectories of Childhood Obesity into Adulthood published on November 30, 2017, with CHDS co-authors Zach Ward and Stephen Resch. Citation: Ward Z, Long M,…

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…

Resource PackPublication, Teaching Resource 2020Resource Pack: SSB Excise Tax Briefs (CHOICES)
Rising rates of obesity represent one of the greatest public health threats facing the United …
Rising rates of obesity represent one of the greatest public health threats facing the United States. Obesity has been linked to excess consumption of sugary drinks. Federal, state, and local governments have considered implementing excise taxes on sugary drinks to reduce consumption, reduce obesity, and provide a new source of government revenue. This resource pack includes a series of briefs describing analyses conducted by the Childhood Obesity Intervention Cost-Effectiveness Study (CHOICES), evaluating the health and economic impact…

ArticlePublication 2013Nutritional Policy Changes in SNAP: A Microsimulation and Cost-Effectiveness Analysis
This analysis estimated the health effects and cost-effectiveness of banning or taxing sugar-sweetened beverages (SSBs) …
This analysis estimated the health effects and cost-effectiveness of banning or taxing sugar-sweetened beverages (SSBs) or subsidizing fruits and vegetables purchased with SNAP. The target population was adults in the U.S. and the time horizon was 10 years. Results showed that banning SSB purchases using SNAP benefits would be expected to avert 510,000 diabetes person-years and 52,000 deaths from MIs and strokes over the next decade, with a savings of $2900 per QALY saved. A…

ArticlePublication 2019Cost-Effectiveness of U.S. National SSB Tax with a Multistakeholder Approach: Who Pays and Who Benefits
This analysis estimated the health impact and cost-effectiveness of a national penny-per-ounce sugar-sweetened beverage (SSB) …
This analysis estimated the health impact and cost-effectiveness of a national penny-per-ounce sugar-sweetened beverage (SSB) tax, overall and with stratified costs and benefits for nine distinct stakeholder groups. A microsimulation model (CVD PREDICT) was used to estimate cardiovascular disease reductions, quality-adjusted life years gained, and cost-effectiveness for U.S. adults aged 35 to 85 years, evaluating full and partial consumer price pass-through. Results showed that from both a health care and societal perspective, the SSB tax was…

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…
