Abstract

A system for linking corresponding patient information records is disclosed. A plurality of entities (1,1a) have respective patient databases comprising patient information records (3, 3a). Each entity (1, 1a) has associated therewith a patient identification algorithm (4,4a) for matching corresponding patient information records (3, 3a) of the same patient at different entities (1,1a). A linking subsystem (6) maintains a set of links (7) of a first entity (1) of the plurality of entities (1,1a). The linking subsystem (6) is arranged for linking patient information records (3) of the first entity (1) with corresponding patient information records (3a) of the other entities (1a). A link (ID, RID, RLoc) is established when a given patient information record (3) of the first entity (1) matches a corresponding patient information record (3a) of another entity (1a) based on the patient identification algorithm (4) of the first entity (1). The links provide an association between locally-assigned patient identifiers (ID, RID) of the same patient at different entities (1,1a).

First claim

The invention claimed is:

1. A system that links patient information records, of a same patient, that are stored at different facilities, comprising:
a plurality of facilities, each facility including:
one or more patient databases comprising patient information records;
a facility specific patient identification algorithm, stored in computer memory, that matches patient information records, of the same patient, located at its facility of the plurality of facilities with the patient information records, of the same patient, located at other facilities of the plurality of facilities;
a linking subsystem, implemented via a microprocessor, that maintains a set of links between its facility and the other facilities of the plurality of facilities, and each link of the set of links represents a facility specific match and each link is stored in computer memory, wherein each link comprises an entity identifier;

wherein the linking subsystem of a first facility of the plurality of facilities links patient information records, of the same patient, located at the first facility with corresponding patient information records, of the same patient, located at a second facility of the plurality of facilities creating a first link of the set of links of the first facility in response to a first facility specific patient identification algorithm of the first facility matching the patient information record, of the same patient, located at the first facility with a corresponding patient information record, of the same patient, located at the second facility;
wherein the linking subsystem of the second facility of the plurality of facilities links patient information records, of the same patient, located at the second facility with corresponding patient information records, of the same patient, located at the first facility of the plurality of facilities creating a first link of the set of links of the second facility in response to a second facility specific patient identification algorithm of the second facility matching the patient information record, of the same patient, located at the second facility with the corresponding patient information record, of the same patient, located at the first facility,
wherein the first facility specific patient identification algorithm and the second facility specific patient identification algorithm are different,
wherein the first link of the first facility and the first link of the second facility are different links;
wherein at least the first facility locally stores a copy of at least a sub-set of the corresponding patient information records, of the same patient, located at the second facility of the plurality of facilities, and the facility specific patient identification algorithm of the first facility employs the locally stored copy to match the patient information records from the second facility; and
wherein the facility specific patient identification algorithm of the first facility matches the patient identification records between the patient information record of the same patient of the second facility and the patient record of the same patient of a third facility with at least one of a different threshold for acceptance and different weighted attributes.

2. The system according to claim 1 , wherein the links provide an association between locally-assigned patient identifiers of the same patient at different facilities.

3. The system according to claim 1 , further comprising:
a central repository that stores a copy of information used by the facility specific patient identification algorithms of each of the plurality of facilities to match the patient information records according to each of the plurality of facilities.

4. The system according to claim 1 , comprising:
an initialization subsystem for initially setting up the set of links for the first facility, processing substantially all available patient information records of the first facility and corresponding patient information records received by the first facility for each other facility of the plurality of facilities, each link in the set of links representing a link to patient information records at a corresponding facility.

5. The system according to claim 1 , wherein each link is a single directional match from a local patient identification to a remote patient identification between the facility and a remote facility and includes the local patient identification, a remote facility identification, and the remote patient identification.

6. The system according to claim 1 , wherein the linking subsystem of the first facility updates the set of links of the first facility on demand or each time a new patient identifier is generated at one of the facilities.

7. The system according to claim 1 , wherein the facility specific patient identification algorithm of the first facility and facility specific patient identification algorithm of the second facility match patient demographic data differently by at least one of an attribute and a weight of an attribute.

8. The system according to claim 7 , wherein the demographic data attributes includes at least one of: a name, an address, a social security number, a personal identification number, a tax number, an age, a date of birth, or a gender.

9. The system according to claim 1 , wherein the patient identification algorithm includes thresholds for at least one of acceptance of a match or rejection of a match which are specific for the facility associated with the patient identification algorithm.

10. A medical workstation which is part of the first facility according to claim 1 , the medical workstation comprising a display for displaying patient information from a patient information record of at least the second facility which is linked with a patient information record of the first facility.

11. A computer-implemented method of linking corresponding patient information records at a plurality of facilities, each facility having respective patient databases comprising patient information records, each facility having associated therewith a patient identification algorithm for matching corresponding patient information records of a same patient at different entities, the method comprising:
maintaining, via a microprocessor, a first set of links of a first facility of the plurality of facilities, the first set of links linking patient information records of the first facility with corresponding patient information records of other facilities, a first link of the first set of links being established when a given patient information record of the first facility matches a corresponding patient information record of another facility, based on a first patient identification algorithm of the first facility, and each link in the set of links representing a facility specific link to the corresponding patient information record of another facility of the plurality of facilities and each link is stored in computer memory;
maintaining, via the microprocessor, a second set of links of a second facility of the plurality of facilities, the second set of links linking patient information records of the second facility with corresponding patient information records of the other facilities, a second link of the second set of links being established when a given patient information record of the second facility matches a corresponding patient information record of another facility, based on a second patient identification algorithm of the second facility, wherein the first patient identification algorithm of the first facility creates the first link and the second patient identification algorithm of the second facility creates the second link;
wherein the first patient identifi
