1. A system to aid in identifying patients potentially seeking inappropriate health care, said system comprising:
- a plurality of patient characteristics for a plurality of patients, said patient characteristics representing medical usage and psychological information about said patients; and
a neural network responsive to input variables generated from said plurality of patient characteristics, said neural network configured to categorize the plurality of patients according to utilization characteristics of said patients based on said input variables, one category of utilization characteristics identifying patients who are potentially seeking inappropriate health care.

Abstract
An apparatus and method for categorizing health care utilization provides an efficient aid in identifying patients who are seeking inappropriate care. The invention involves a computer system having a neural network responsive to several input variables to categorize the utilization characteristics of the patient. The input variables define selected characteristics of a patient. In one embodiment, a screening process identifies patients who are at high risk to an immediate threat to their health and eliminates those least likely to be seeking inappropriate care.

2. A method for categorizing health care utilization of a plurality of patients, said method comprising the steps of:
-
defining a set of input variables having input values which define selected characteristics of each of the plurality of patients; forming an input vector for a neural network based upon said set of input variables for each of the plurality of patients; and analyzing said input vector with said neural network to categorize the health care utilization of at least some of the plurality of patients into at least one of a selected plurality of health care utilization categories. - View Dependent Claims (3, 4, 5, 6, 7, 8)

9. A method for training a neural network to categorize health care utilization of a plurality of patients, said method comprising the steps of:
-
(a) defining a set of input variables having input values which define selected characteristics of each of a plurality of patients, said plurality of patients forming a training set; (b) defining at least two categories of health care utilization for said patients; (c) selecting which of said at least two categories applies to each of said plurality of patients; (d) providing said input variables for each patient and the selected category for each patient, to the neural network, the selected category for each patient category forming a target output value; (e) analyzing the input variables with the neural network to obtain a first output value associated with said set of input variables; (f) comparing said first output value with said target output value; (g) adjusting weights in the neural network if said first output value does not equal said target output value to partially compensate for the difference between the target output value and the first output value; and (h) repeating steps (d) through (g) for each of said plurality of patients in the training set until said first output value is substantially the same as said target output value or no more improvement is attained.
