Abstract
The present invention provides a data mining framework for mining high-quality structured clinical information. The data mining framework includes a data miner that mines medical information from a computerized patient record (CPR) based on domain-specific knowledge contained in a knowledge base. The data miner includes components for extracting information from the CPR, combining all available evidence in a principled fashion over time, and drawing inferences from this combination process. The mined medical information is stored in a structured CPR which can be a data warehouse.
Claims54
A system for producing structured clinical information from patient records, comprising:
- a plurality of data sources containing patient information, at least some of the patient information being unstructured;
- a domain knowledge base containing domain-specific criteria for mining the data sources;
- and
- a data miner for extracting clinical information from the data sources using the domain-specific criteria, to create structured clinical information.
The system of step 1, wherein the data miner is run at arbitrary intervals.
The system of step 1, wherein the data miner is run in online mode.
A method for producing structured clinical information from patient records, comprising the steps of:
- providing a plurality of data sources containing patient information, at least some of the patient information being unstructured;
- providing a domain knowledge base containing domain-specific criteria for mining the data sources;
- and
- extracting clinical information from the data sources using the domain-specific criteria, to create structured clinical information.
A program storage device readable by a machine, tangibly embodying a program of instructions executable on the machine to perform method steps for producing structured clinical information from patient records, the method steps comprising:
- providing a plurality of data sources containing patient information, at least some of the patient information being unstructured;
- providing a domain knowledge base containing domain-specific criteria for mining the data sources;
- and
- extracting clinical information from the data sources using the domain-specific criteria, to create structured clinical information.
