Automated medical decision making utilizing bayesian network knowledge domain modeling

A computerized system for providing automated medical triage to a patient under study comprising:

• a server including processing means and memory means, said memory means comprising a Bayesian Network, wherein said Bayesian Network comprises a plurality of instantiable nodes, a plurality of fault nodes, a utility node and a decision node;
• a remote computer accessible by a patient under study;
• a network allowing access by said remote computer to said server;
• a scoring mechanism to adjust said probabilities in said diagnosis node responsive to information input by said patient under study into said remote computer.

A method for providing automated medical decision-making comprising:

• establishing a Bayesian Network comprising:
• a plurality of instantiable nodes for entering evidence;
• a plurality of fault nodes in communication with said instantiable nodes for providing results capable of being monitored;
• a utility node for providing quantitative information to a decision node having states;
• and said decision node, wherein said decision node calculates a utility value for each of said states;
• obtaining evidence from a patient-under-study;
• entering said evidence into selected ones of said instantiable nodes;
• monitoring said fault nodes for,said results;
• using said results in said utility node;
• and
• outputting a result in said decision node based upon said quantitative information in said utility node.
