Decision Maker

Decision Maker^©

Decision Maker^© is a computer program developed at the Division of Clinical Decision Making at Tufts Medical Center which permits the development of user defined decision trees and provides general analytic capabilities for decision trees using the basic principles of decision analysis with particular emphasis on the approaches used in the clinical and health policy arenas. The current version is 7.07.

Decision Maker operates on any MS-DOS (IBM or IBM compatible personal computer) under Windows or DOS. It uses a graphical interface with pull down menus, performs simple fold-backs, cost-effectiveness analyses, Markov and Monte Carlo analyses, and sensitivity analyses.
