摘要

The purpose of this paper is to show how features of the HELP system for medical decision making provide an ideal basis upon which to implement decision analysis. We have applied decision analysis to the decisions which a physician must make when treating typical angina which may be caused by coronary artery disease. Modular HELP oriented logic is used to construct a decision tree. The use of HELP logic modules (HELP sectors) for each node in the tree allows patient specific decisions to be generated. This logic was applied to 729 patients who have undergone coronary artery surgery.
