System and method for implementing a global master patient index
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.
1. A computer-implemented method comprising:
receiving information about a patient record;
in response to receiving the information about the patient record, performing a search through one or more databases of records for one or more matching records that match the patient record;
for each of the one or more matching records that are found through the search, creating an unconfirmed link between that matching record and the patient record; and
in response to input from a user regarding a selected record that is from the group consisting of said patient record and the one or more matching records, converting the unconfirmed link for the selected record to a directional confirmed link identifying which of the selected record and the linked record identified by the unconfirmed link for the selected record is a leader record, wherein the leader record among two linked records is the record among the two linked records that is at least one of most current, most correct, and most proper, wherein receiving information, performing the search, creating unconfirmed links, and converting unconfirmed links is performed by a computer system.
2. The method of claim 1 , wherein the information about the patient record is information that is to be stored in a new patient record.
3. The method of claim 1 , wherein 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:
receiving search criteria from the user;
performing a search for records that match to the search criteria;
displaying a list of records that match the search criteria;
receiving user input choosing one of the records from the list of records, wherein the chosen record is said selected record; and
receiving user input specifying confirmation information for the unconfirmed link of the selected record.
5. The method of claim 4 , further comprising in response to receiving further input at a later time changing the directional confirmed link to a certified link.
6. The method of claim 1 , wherein performing the search through one or more databases of records comprises using real world primary key information from the patient record to identify the one or more matching records.
7. The method of claim 6 , wherein the real world primary key information includes any of a first name, a last name, a social security number, a gender, and a date of birth for a patient.
8. The method of claim 1 , wherein receiving information about a patient record involves receiving information for creating a new record for a patient.
9. The method of claim 1 , wherein the record among the two linked records to which the leader record is linked is a trailer and wherein converting the unconfirmed link to a directional confirmed link comprises modifying the leader record based on information in the trailer record.
