First Claim
1. A method of extracting a pre-defined data item from unstructured medical service records stored in a central data processing system and generated by a plurality of service providers, comprising the steps of:
- storing the unstructured medical service records in a database of the central data processing system for a plurality of individuals having previously sought or received services from at least one of a plurality of service providers, each unstructured medical service record contains a plurality of spatially-organized groupings of unfielded and free form text;
identifying each spatially-organized grouping as one of a plurality of structural element designations using a rules-based application predicated at least in part on the structural element designations and a document type associated with a particular service provider; and
extracting the pre-defined data item from one of the plurality of spatially-organized groupings by executing the rules-based application.

Abstract
A central medical record repository for a managed health care organization accepts and stores medical record documents in any format from medical service providers. The repository then identifies the document using information automatically extracted from the document and stores the extracted data in a document database. The repository links the document to a patient by extracting from the document demographic data identifying the patient and matching it to data stored in a patient database. Data is extracted automatically from medical records containing "unstructured" or free-form text by identifying conventional organization components in the text and is organized by executing rules that extract data with the aid of such information. Documents for a patient are retrieved by identifying the patient using demographic data.
