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 2001Cost-Benefit Analysis of a Strategy to Vaccinate Healthy Working Adults against Influenza
The authors performed a cost-benefit analysis to assess the economic impact of vaccinating healthy working …
The authors performed a cost-benefit analysis to assess the economic impact of vaccinating healthy working adults between 18 and 64 years old with an influenza vaccine. Monte Carlo simulation was used to calculate the direct and indirect costs associated with vaccination and those prevented by vaccination. The authors found that vaccinating healthy working adults was, on average, cost-saving.

ArticlePublication 2017Estimating the Fitness Cost and Benefit of Cefixime Resistance in Neisseria Gonorrhoeae
Gonorrhoea is one of the most common bacterial sexually transmitted infections in England, and more …
Gonorrhoea is one of the most common bacterial sexually transmitted infections in England, and more than half of annual infections occur in men who have sex with men (MSM). As the bacterium has developed resistance to each first-line antibiotic in turn, an improved understanding is needed of fitness benefits and costs of antibiotic resistance to inform control policy and planning. The authors developed a stochastic compartmental model representing the natural history and transmission of cefixime-sensitive…

The Global Health Cost Consortium (GHCC) is a new three-year initiative funded by the Bill and Melinda Gates Foundation to provide decision-makers with improved resources to estimate the costs of HIV and tuberculosis (TB) programs. GHCC’s goal is to increase the efficiency and effectiveness of HIV and TB prevention and treatment, and drive greater value for money of investments to tackle HIV and TB in low and middle-income countries, by improving the availability, quality, timing, and…

The Society for Risk Analysis (SRA) is a multidisciplinary, interdisciplinary, scholarly, international society that provides an open forum for all those who are interested in risk analysis. Risk analysis is broadly defined to include risk assessment, characterization, communication, management, and policy. It covers risks of concern to individuals, to public- and private-sector organizations, and to society at a local, regional, national, or global level. The Society includes numerous regional organizations around the world as well as several…

This module examines three scientific areas that provide evidence bearing on causation in the “toxic …
This module examines three scientific areas that provide evidence bearing on causation in the “toxic tort” or environmental disease context: epidemiology, toxicology, and genetics. These scientific disciplines are used in civil lawsuits and in regulatory proceedings in which causation or risk is an issue. The module is appropriate for non-scientist law students as well as others interested in learning the science of toxic tort causation, including practicing attorneys, judges, and public policy and public health…
