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…

ReviewPublication 2005Implications of Modern Decision Science for Military Decision-Support Systems
This review monograph was prepared in response to a request from the United States Air …
This review monograph was prepared in response to a request from the United States Air Force Research Laboratory for a study of modern decision science that would aid in its planning of research programs and, more specifically, developing methods and tools for decision support. The emphasis is on relatively high-level decisionmaking rather than, say, that of pilots or intelligence analysts in the midst of real-time operations. They focus largely on what the military refers to as…

ArticlePublication 2000Discipline of Cost-Benefit Analysis
Cost-benefit analysis is a general discipline, based on the use of some foundational principles, which …
Cost-benefit analysis is a general discipline, based on the use of some foundational principles, which are not altogether controversial, but have nevertheless considered plausibility. Divisiveness increases as various additional requirements are imposed. There is a trade-off here between easier usability (through locked-up formulae) and more general acceptability (through allowing parametric variations). The paper, by Amartya Sen, examines and scrutinizes the merits and demerits of these additional requirements. The particular variant of cost-benefit approach that is…

ArticlePublication 2000Preference-Based Measures in Economic Evaluation in Health Care
Estimating preferences for states of health has been an active area of research in recent …
Estimating preferences for states of health has been an active area of research in recent years. Unlike psychophysical approaches, which discriminate levels of health status, preference-based approaches incorporate values or utilities for health outcomes and can be used in cost-effectiveness analyses to aid resource allocation decisions. This chapter considers issues and controversies involved in using preference-based measures in economic evaluation in health care, with a particular emphasis on cost-utility analysis and the estimation of quality-adjusted…

ArticlePublication 2000Valuing Mortality Risk: Theory and Practice
This article discusses the theoretical foundation and empirical methods for estimating the value of a …
This article discusses the theoretical foundation and empirical methods for estimating the value of a statistical life (VSL). VSL is defined by individuals' preferences for small changes in risk and income, and often used by environmental and other economists to measure the monetary value of reduced mortality risk. The article reviews the dependence of VSL on age, income, baseline mortality risk, and latency.

In 1993, the US Public Health Service convened a panel of 13 nongovernment scientists and scholars with expertise in economics, clinical medicine, ethics, and statistics to review the state of cost-effectiveness analysis and to develop recommendations for its conduct and use in health and medicine. Publishing their results in 1996, they proposed the most explicit set of guidelines (together with their rationale) ever defined on the conduct of CEAs. The panel recommended analysts include a "reference-case"…

This article, written for the non-decision analyst, describes what decision analysis is, what it can …
This article, written for the non-decision analyst, describes what decision analysis is, what it can and cannot do, why one should care to do this, and how one does it. Keeney describes decision analysis as "a formalization of common sense for decision problems which are too complex for informal use of common sense." He provides a more technical definition also, describing decision analysis as "a philosophy, articulated by a set of logical axioms, and a methodology…

The limitations of diagnostic "accuracy" as a measure of decision performance require introduction of the …
The limitations of diagnostic "accuracy" as a measure of decision performance require introduction of the concepts of the "sensitivity" and "specificity" yet even these do not provide a unique description of diagnostic performance because they depend on the arbitrary selection of a decision threshold. The receiver operating characteristic (ROC) curve is shown to be a simple yet complete empirical description of this decision threshold effect, indicating all possible combinations of the relative frequencies of the…
