Method and system to optimize quality of patient care paths
First Claim
1. A method of optimizing a medical care plan, the method comprising:
- describing aspects of a care plan as a plurality of worksteps organized by a rule-based process;
analyzing a data base of information relating to a success probability measure of a care plan, the probability including at least one of medical diagnosis, cost, or outcome;
modifying the care plan by changing the rule-based process so as to increase the success probability measure.

Abstract
A system and method for optimizing status of a care plan is described, the method including defining a care plan as worksteps associated by a rule-based process. Historical data is collected for a plurality of worksteps for such attributes as diagnosis, clinical outcome and cost. The data may be analyzed by data mining techniques so as to discover the optimum relationships between the patient symptoms, the worksteps and a success criteria. The success criteria may include correct diagnosis, equipment use efficiency, cost, and successful clinical outcome. The rule-based process may be modified to take account of the optimum relationships. A patient presenting with a constellation of symptoms may have the symptoms compared with care plans success ranking to determine an optimum care plan.

6. A method of improving medical diagnosis, the method including:
-
compiling a list of symptoms reported by patients; compiling a list of questions asked by medical personnel in response to a symptom or constellation of symptoms; compiling a list of diagnosed medical syndromes; determining a joint likelihood of a specific symptom or constellation of symptoms, the asked questions and the diagnosis; and selecting the symptoms and asked questions having the highest likelihood of resulting in the diagnosis, wherein the data base of symptoms, asked questions and diagnosis is analyzed by data mining. - View Dependent Claims (7, 8, 9)

10. A data processing system for optimizing a medical care plan, the system comprising:
-
a computer executing a software program product operable to; maintain a care plan having worksteps, the worksteps being linked by a rule-based process; accept data from worksteps performed in a clinical care path, the data including at least one of clinical outcome, diagnosis, or cost; determine an optimum care plan configuration with respect to at least one of clinical outcome, diagnosis or cost by analyzing the data using data mining techniques.

11. A computer-readable medium having instructions executable on a computer stored thereon, the instructions causing a computer system to:
-
store and maintain a care plan having worksteps, the worksteps being related by a rule-based process; accept data input associated with the performance of worksteps including at least one of patient symptoms, cost, clinical outcome, or diagnosis; analyze the effectiveness of the rule-based process with respect to at least one of cost, clinical outcome, or diagnosis, based on use of data mining; and identify modifications of the rule-based process so as to increase the effectiveness of he care plan. - View Dependent Claims (12, 13)
