Abstract

A method and system for patient generation and evolution for a computer-based testing system and/or expert system. One or more belief networks (222, 224, 228), which describe parallel health state networks (222, 224, 228) are accessed by a user or a computer (254, 262, 264, 266, 268). A knowledge base, at least in part, is scripted from the one or more belief networks (222, 224, 228) by the computer (254, 262, 264, 266, 268). A model patient at least in part, is instantiated by the computer (254, 262, 264, 266, 268) from the scripted knowledge base. Optionally, the model patient is evolved by the computer (254, 262, 264, 266, 268) in accordance with the parallel health state networks (222, 224, 228) and responsive to a received course of action.

a computer-readable medium storing instructions executable by said processor, said instructions including at least one of:
generating a virtual patient based, at least in part, on at least one first belief network, which describes a plurality of parallel health state networks;
generating the virtual patient based, at least in part, on at least one second belief network, which describes rates of progression within and/or between the plurality of parallel health state networks; and generating patient test data concerning the virtual patient, based, at least in part, on at least one third belief network, which supports reveal structures to limit display of the patient test data to patient test data specifically requested by the user.
47. The computer system according to claim 47, wherein said computer system is communicatable with a user via a computer network.
48. A computer system for evaluating or educating a user, comprising:
a processor;
a computer-readable medium storing instructions executable by said processor, said instructions including at least one of:
generating a virtual patient based, at least in part, on at least one causal probabilistic network, which describes a plurality of parallel health state networks;
generating the virtual patient based, at least in part, on the at least one causal probabilistic network, which describes rates of progression within and/or between the plurality of parallel health state networks; and generating patient test data concerning the virtual patient, based, at least in part, on the at least one causal probabilistic network, which supports reveal structures to limit display of the patient test data to patient test data specifically requested by the user.
49. The computer system according to claim 48, wherein said computer system is communicatable with a user via a computer network.
