This tutorial illustrates the basic steps needed to develop decision trees in Amua using a disease screening example. It details the process of how to build the structure of a decision tree, parameterize the model with probabilities and relevant outcomes (i.e., life expectancy), evaluate three alternative screening strategies in a baseline scenario, and perform one-way sensitivity analyses to assess the robustness of the results to different parameter values. Amua, the Swahili word meaning “decide”/“solve”, is…

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…

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’…

These three videos, produced by Khan Academy, focus on conditional probability. Conditional probability with Bayes' Theorem (~5 min). Created by Brit Cruise, this video presents conditional probability visually using trees. Conditional probability and independence (~4 min). This video uses conditional probability to see if events are independent or not. Conditional probability tree diagram (~11 min). This video uses a tree diagram to work out the following conditional probability question: If someone fails a drug test, what is the…

Tutorial/PrimerPublication, Teaching Resource 1980Threshold Approach to Clinical Decision Making
This classic paper provides a "tutorial" for students learning about diagnostic testing, probability revision, and …
This classic paper provides a "tutorial" for students learning about diagnostic testing, probability revision, and how to calculate thresholds for testing, treatment, and no treatment. The authors describe how a physician's estimate of the probability that a patient has a particular disease is a principal factor in the determination of whether to withhold treatment, obtain more data by testing, or treat without subjecting the patient to the risks of further diagnostic tests. Using the concepts of decision analysis,…
