Abstract: The system and method for graphic creation of a medical logical module in the Arden syntax file format allows a user to define a medical decision process in terms of flowcharts and outlines. The system and method provide for creation of a medical logical module for a computer in the Arden syntax file format. A graphic representation of a medical decision logic tree of a connected series of a plurality of nodes in a medical decision process is encoded, with each node having a logical path from the node, and each connected series of nodes containing at least one intermediate node and a concluding node. For each node, a conditional statement is encoded for each path from the node; a definition of a path for each intermediate node is encoded; and an outcome for each concluding node is encoded.
