Abstract

A data management system accepts input documents having a variety of formats from multiple sources. Typically one or more formats are associated with a source. A document reader parses an input documents using a set of rules. The rules are tailored to the source that provided the document. The rules use format and context to extract data. The data extracted from the input document is stored in a document database and indexed. Typically, demographic data and clinical data are extracted from the input document and the demographic data is used to index the document.

Claims

1. A method for storing data from a plurality of sources, comprising:

receiving a plurality of input documents, each input document including demographic information;

parsing each input document by applying a set of rules corresponding to the source associated with the input document to extract demographic data and clinical data;

storing the extracted data in a document database;

determining whether the demographic data corresponds to an existing index record; and

if the demographic data corresponds to an existing index record, then indexing the extracted data based on the demographic data.

2. The method of claim 1, further comprising:

storing the input document;

updating the set of rules corresponding to the source;

re-parsing the input document by applying the updated set of rules to extract updated demographic data and updated clinical data; and

storing the updated extracted data in the document database.

3. The method of claim 1, further comprising:

if the individual information does not correspond to an existing index record, then creating an index record using the demographic information.

4. The method of claim 1, further comprising:

comparing a value extracted from the input document to a predetermined value;

based on the comparison, identifying a treatment guideline; and

comparing the treatment guideline with a treatment extracted from the input document.

5. The method of claim 4, further comprising:

based on the treatment comparison, providing a notice of the comparison.

6. The method of claim 1, further comprising:

comparing a condition extracted from the input document to a predetermined condition;

based on the comparison, identifying a treatment guideline; and

comparing the treatment guideline with a treatment extracted from the input document.

7. The method of claim 6, further comprising:

based on the treatment comparison, providing a notice of the comparison.

8. The method of claim 1, wherein one of the documents is a transcribed document.

9. The method of claim 1, wherein one of the documents is an HL7 message.

10. The method of claim 1, wherein the set of rules includes a rule based on a location in the input document.

11. The method of claim 1, wherein the set of rules includes a rule based on a field in the input document.

12. The method of claim 1, wherein the set of rules includes a rule based on context of the input document.

14. The system of claim 13, further comprising:

an audit database for storing audit information; and

an audit broker operative to store and retrieve audit information from the audit database and to communicate with the index broker.

15. The system of claim 13, further comprising:

an authorization database for storing authorization information; and

an authorization broker operative to store and retrieve authorization information from the authorization database and to communicate with the index broker.

16. The system of claim 13, further comprising:

a care guidelines database for storing care guidelines information; and

a care guidelines broker operative to store and retrieve care guidelines information from the care guidelines database and to communicate with the document broker.

17. The system of claim 13, further comprising:

a practice-specific database for storing practice specific information; and

a practice-specific broker operative to store and retrieve practice specific information from the practice specific database and to communicate with the document broker.

19. The method of claim 17, wherein the source is a transcription service and the input document is a transcribed document.

20. The method of claim 17, wherein reporting results of the comparison comprises providing an electronic mail notification.

21. The method of claim 17, wherein reporting results of the comparison comprises storing the results with the extracted data.

22. The method of claim 17, wherein the extracted data is stored in a document database and the demographic data is used to index the extracted data in an index database.

24. The method of claim 23, wherein retrieving the document comprises:

receiving a search request that includes identification information for a patient;

based on the identification information, identifying demographic data that corresponds to the patient;

using the demographic data to identify the document;

receiving a document selection for the document; and

providing the document in response to the document selection.

25. The method of claim 24, wherein identifying the document comprises:

displaying a document identifier that corresponds to the document on a display device.

26. The method of claim 24, wherein providing the document comprises:

displaying the document on a display device.

27. The method of claim 24, wherein the identification information comprises a portion of a name.

28. The method of claim 24, wherein the identification information comprises a date of birth.

29. The method of claim 24, wherein the identification information comprises a medical record number.

13. A system for storing data received from multiple sources, comprising:

a plurality of document readers, wherein each document reader is associated with a different source and each document reader is associated with a set of rules, is operative to extract data from an input document received from its associated source using the set of rules and is operative to communicate with an index broker and a document broker;

an index database for storing demographic data extracted from the documents and indexing the extracted data;

the index broker operative to receive data from the document readers, to store and retrieve data from the index database and to communicate with the document broker;

a document database for storing the extracted data from the input documents; and

the document broker operative to receive the extracted data from the document readers, to store and retrieve data from the document database and to communicate with the index broker.

18. A method for storing data, comprising:

receiving an input document from a source;

identifying a set of rules associated with the source that use format and context to extract data;

applying the set of rules to the input document to extract demographic data and clinical data;

comparing the clinical data to care guideline information;

reporting results of the comparison;

storing the demographic data and the clinical data; and

indexing the extracted data using the demographic data.

23. A method for storing and retrieving medical documents, comprising:

receiving an input medical document from a source;

identifying a set of rules based on the source;

applying the set of rules to the input medical document to extract demographic data and clinical data;

storing the demographic data and clinical data as a document;

indexing the document using the demographic data; and

retrieving the document.
