Abstract

Separate computer systems may participate in a Health Data Network (HDN) such that the computer systems are linked so as to share various types of healthcare-related information. The shared information may include patient record information. The integration of the patient record information is accomplished by maintaining a Global Master Patient Index (GMPI). Such a GMPI may integrate patient record information used by multiple healthcare organizations, facilities, or businesses. Such a GMPI may also integrate patient record information for a single business having multiple sites or computer systems, e.g., a large hospital. The GMPI preferably provides for performing functions such as locating patient records, locating duplicate records for a selected patient, printing a selected patient record with all its duplicate patient records, reconciling potential duplicate patient records found while searching and retrieving a patient'"'"'s record final reconciliation (certification) of suspected duplicate patients records, maintaining a persistent relationship between patient records in the GMPI, and maintaining a reconciliation audit trail.

Claims

1. A method for maintaining a Global Master Patient Index (GMPI), the method comprising:

receiving information specifying changes to a patient record;

performing a search through one or more databases for one or more matching records that match the patient record, in response to the received information; and

if one or more matching records are found, creating an unconfirmed link between the patient record and each matching record.

2. The method of claim 1,

wherein the information specifying changes to a patient record is information specifying a new patient record;

wherein said performing a search through one or more databases comprises performing a search for one or more records that match the new patient record.

3. The method of claim 1,

wherein said performing the search through one or more databases for one or more matching records that match the patient record is based on real world primary key information.

4. The method of claim 1, further comprising:

performing a search for a patient record in response to user input search criteria;

displaying a list of records that match the search criteria, wherein the list includes a set of two or more records that have unconfirmed links between the records;

receiving user input selecting one of the records from the set;

receiving user input specifying confirmation information for the unconfirmed links.

5. The method of claim 4,

wherein in response to the confirmation information for an unconfirmed link the link is either:

1) confirmed or

     2) denigrated.

6. The method of claim 5, further comprising:

receiving user input changing a confirmed link to a certified link.
