Medical Decision Making: Probabilistic Medical Reasoning
نویسندگان
چکیده
After reading this chapter, you should know the answers to these questions: • How is the concept of probability useful for understanding test results and for making medical decisions that involve uncertainty? • How can we characterize the ability of a test to discriminate between disease and health? • What information do we need to interpret test results accurately? • What is expected-value decision making? How can this methodology help us to understand particular medical problems? • What are utilities and how can we use them to represent patients’ preferences? • What is a sensitivity analysis? How can we use it to examine the robustness of a decision and to identify the important variables in a decision? • What are influence diagrams? How do they differ from decision trees?

Cateegorical and Probabilistic Reasoning in Medical Diagnosis *
Medical decision making can be viewed along a spectrum, with categorical (or deterministic) reasoning at one extreme and probabilistic (or evidential) reasoning at the other. In this paper we examine the flowchart as the prototype of categorical reasoning and decision analysis as the prototype of probabilistic reasoning. Within this context we compare PIP, INTERNIST, CASNET, and MYCZN-four of t...
متن کاملTeaching Therapeutic Reasoning Through the Case-Study Approach: Adding the Probabilistic Dimension
Case-studies are vehicles for implementing problem-based learning in the curriculum. The main objectives of problembased learning as achieved through case studies are to instill in students principles of self-learning and critical thinking. Pharmacotherapeutic case studies are also used to integrate knowledge from different pharmaceutical disciplines (medicinal chemistry) and illustrate their c...
متن کاملCategorical and Probabilistic Reasoning in Medical Diagnosis
In the mid-1970s, when Gorry left M.I. T. to go to Baylor College of Medicine, Peter Szolovits took over as head of the Clinical Decision-Making Group at Project MAC (now known as the Laboratory for Computer Science). He renewed ties with the collaborators at Tufts University with whom Gorry had previously worked (Pauker, Schwartz, and Kassirer). The following chapter is an early result of thos...
متن کاملProbability or Reasoning: Current Thinking and Realistic Strategies for Improved Medical Decisions
A prescriptive model approach in decision making could help achieve better diagnostic accuracy in clinical practice through methods that are less reliant on probabilistic assessments. Various prescriptive measures aimed at regulating factors that influence heuristics and clinical reasoning could support clinical decision-making process. Clinicians could avoid time-consuming decision-making meth...
متن کاملArgumentation and Decision Making: A Position Paper
This paper summarises our position on the use of symbolic methods for reasoning under uncertainty, and argumentation in particular. Our view is that argumentation ooers a complement to numerical methods for reasoning about belief, and a general framework within which many competing approaches can be understood. In applications we have found that argumentation ooers a variety of beneets for prac...
