Abstract
We describe a computerized aid to the study of the cost-effectiveness of medical practices. CE-TREE is a conversational system allowing the user to define and manipulate decision trees for comparing alternative clinical strategies. In contrast to the usual medical application of decision analysis, CE-TREE encourages the simultaneous comparison of strategies using several different outcome measures, which are specified by the user. This mode of comparison makes explicit the trade-offs involved in choosing one strategy over another.
CE-TREE provides a number of useful functions for the management and analysis of decision trees. The system is written in Standard MUMPS, and runs on popular minicomputers or microprocessors. It has been used by several physician investigators to study a number of clinical problems and public health issues.
