This tutorial illustrates the basic steps needed to develop decision trees in Amua using a …
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…

Teaching PackPublication, Teaching Resource 2022Teaching Pack: Probability Revision and Bayes
In this teaching pack on Probability Revision and Bayes, students are introduced to the implications …
In this teaching pack on Probability Revision and Bayes, students are introduced to the implications of imperfect information, acquire a conceptual understanding of Bayes theorem, and gain practical skills in performing probability revision. Materials include an instructor's note, videos, companion slides, a glossary, an annotated bibliography, sample exercises, and additional support. Learning Objectives Demonstrate a conceptual understanding of Bayes’ theorem and probability revision. Differentiate between test characteristics (e.g., probability of positive test given…

In this teaching pack on Using Test Information I, students review the performance of a …
In this teaching pack on Using Test Information I, students review the performance of a dichotomous test and the relationship between sensitivity and specificity, calculate likelihood ratios to describe test performance, and conduct probability revision using the odds-LR form of Bayes. Materials include an instructor's note, videos, companion slides, a glossary, an annotated bibliography, and sample exercises. Learning Objectives Calculate four conditional probabilities describing the performance of a dichotomous test, and explain the…

In this teaching pack on Using Test Information II, students are introduced to tests with …
In this teaching pack on Using Test Information II, students are introduced to tests with continuous or categorical results, and calculate the sensitivity and specificity conditional on different 'cutoff points' or 'positivity criterion'. They are introduced to ROC curves and explore the implications of operating at different parts of the curve for any single test. They calculate the optimal positivity criterion given information on the prior, the test performance, and the relative consequences of true…

OR-Notes are a series of introductory notes on topics that fall under the broad heading of the field of operations research (OR). They were developed and used by J E Beasley in an introductory OR course at Imperial College. He has made them available for use by any students and teachers interested in OR subject provided he is acknowledged and identified as their author. J E Beasley completed his PhD in Management Science at Imperial…

The purpose of the HTA Glossary is to give the Health Technology Assessment (HTA) community – both producers and users of health technology assessment information – a common vocabulary. The HTA glossary is an official collaboration between International Network of Agencies for Health Technology Assessment (INAHTA), Health Technology Assessment international (HTAi) and other partner organizations. The English version of the HTA Glossary is coordinated by Adelaide Health Technology Assessment (AHTA), the French version by l'Institut…

This policy brief aims to explain the cost per DALY threshold and the concepts of …
This policy brief aims to explain the cost per DALY threshold and the concepts of health opportunity costs, especially aimed at low and middle-income countries. The authors state that an assessment of health opportunity costs is required if the best use is to be made of health and healthcare resources. This requires an assessment of whether the improvement in health outcomes they offer exceeds the improvement in health that would have been possible if the…

In this article the authors consider how benefit-cost analysis can be used retrospectively to promote …
In this article the authors consider how benefit-cost analysis can be used retrospectively to promote understanding of the impacts after a policy is implemented. Serving as a brief primer, the authors propose that analysis can be useful for identifying needed reforms as well as in improving the conduct of future prospective analyses. The major challenges relate to estimating what would have occurred in the absence of the policy and separating the effects of the policy…

Tutorial/PrimerPublication, Teaching Resource 2005Refining Clinical Diagnosis with Likelihood Ratios
This article serves as a concise tutorial about the interpretation and use of likelihood ratios …
This article serves as a concise tutorial about the interpretation and use of likelihood ratios in clinical decision-making. Likelihood ratios can refine clinical diagnosis on the basis of signs and symptoms; however, they are underused for patients' care. A likelihood ratio is the percentage of ill people with a given test result divided by the percentage of well individuals with the same result. Ideally, abnormal test results should be much more typical in ill individuals…
