Abstract

Claims (85)

1. A method comprising:

determining, by a collection-side system, a match between:

data for a first healthcare record received from a source-side system, and

data for a second healthcare record previously processed at the collection-side system; and

retrieving, by the collection-side system, an indexing tag that is stored in association with the second healthcare record;

linking de-identified healthcare records that correspond to a single patient, based on the indexing tag, wherein:

the indexing tag is encoded with a computing rule specific to the source-side system, and

the computing rule is based on patient identifying information (PII) extracted from the first healthcare record;

based on the encoded indexing tag, generating, by the collection-side system, a source-specific identifier that anonymously links portions of PII from the de-identified healthcare records that correspond to the single patient; and

triggering, by the collection-side system and based on the source-specific identifier, the source-side system to associate the data for the first healthcare record with a plurality of other healthcare records that include the source-specific identifier.

2. The method of claim 1 , comprising:

obtaining, by the collection-side system, the computing rule specific to the source-side system and the data for the first healthcare record,

wherein the data for the first healthcare record (i) includes information extracted from the first healthcare record with reference to a formatting of the first healthcare record and (ii) is encoded PII that is generated based on the computing rule.

3. The method of claim 1 , wherein the data for the first healthcare record comprises a first hashed token and the method comprises:

comparing, by the collection-side system, the first hashed token to a second hashed token previously received at the collection-side system;

based on the comparing, determining, by the collection-side system and before retrieving the indexing tag, that the indexing tag is related to the second hashed token; and

encoding the indexing tag in a manner specific to the organization associated with the source-side system.

4. The method of claim 1 , comprising:

determining, by the collection-side system, that no healthcare record previously processed at the collection-side system includes data that matches data for a healthcare record received from the source-side system;

generating a new indexing tag to anonymously identify a patient that corresponds to the data for the healthcare record; and

storing the data for the healthcare record in association with the new indexing tag.

5. The method of claim 4 , comprising:

encoding the new indexing tag with the computing rule specific to the source-side system; and

generating, by the collection-side system, a second, different source-specific identifier based on the new indexing tag that was encoded with the computing rule.

6. The method of claim 1 , wherein the respective data for each of the first healthcare record and the second healthcare record includes one or more hashed tokens and determining the match comprises, determining a match between:

a first hashed token of the first healthcare record; and

a second hashed token for second healthcare record.

7. The method of claim 6 , comprising:

obtaining, by the collection-side system, the first hashed token and the second the hashed token, the second hashed token being obtained before the first hashed token;

wherein the first hashed token is generated based on a hashing function that was applied to concatenated strings of PII extracted from the first healthcare record; and

wherein the second hashed token is generated based on the hashing function having been previously applied to concatenated strings of data representing PII extracted from the second healthcare record.

8. The method of claim 6 , comprising:

encoding the indexing tag in a manner specific to a source of the first healthcare record such that the source-specific identifier that is generated based on the indexing tag is configured for use only by the source of the first healthcare record.

9. The method of claim 8 , wherein encoding the indexing tag comprises:

linking, at the collection-side system, de-identified data corresponding to the first healthcare record with de-identified data corresponding to the second healthcare record.

10. The method of claim 7 , wherein:

the computing rule used by the collection-side system to encode the indexing tag is previously used to determine which portions of PII to be extracted from the first healthcare record to generate the first hashed token; and

the computing rule is specific to a geographic region of the first healthcare record or a type classification of the first healthcare record.

11. A system comprising:

one or more processing devices; and

one or more non-transitory machine-readable storage devices storing instructions that are executable by the one or more processing devices to cause performance of operations comprising:

determining, by a collection-side system, a match between:

data for a first healthcare record received from a source-side system, and

data for a second healthcare record previously processed at the collection-side system; and

retrieving, by the collection-side system, an indexing tag that is stored in association with the second healthcare record;

linking de-identified healthcare records that correspond to a single patient, based on the indexing tag, wherein:

the indexing tag is encoded with a computing rule specific to the source-side system, and

the computing rule is based on patient identifying information (PII) extracted from the first healthcare record;

based on the encoded indexing tag, generating, by the collection-side system, a source-specific identifier that anonymously links portions of PII from the de-identified healthcare records that correspond to the single patient; and

triggering, by the collection-side system and based on the source-specific identifier, the source-side system to associate the data for the first healthcare record with a plurality of other healthcare records that include the source-specific identifier.

12. The system of claim 11 , wherein the operations comprise:

obtaining, by the collection-side system, the computing rule specific to the source-side system and the data for the first healthcare record,

wherein the data for the first healthcare record (i) includes information extracted from the first healthcare record with reference to a formatting of the first healthcare record and (ii) is encoded PII that is generated based on the computing rule.

13. The system of claim 11 , wherein the data for the first healthcare record comprises a first hashed token and the operations comprise:

comparing, by the collection-side system, the first hashed token to a second hashed token previously received at the collection-side system;

based on the comparing, determining, by the collection-side system and before retrieving the indexing tag, that the indexing tag is related to the second hashed token; and

encoding the indexing tag in a manner specific to the organization associated with the source-side system.

14. The system of claim 11 , wherein the operations comprise:

determining, by the collection-side system, that no healthcare record previously processed at the collection-side system includes data that matches data for a healthcare record received from the source-side system;

generating a new indexing tag to anonymously identify a patient that corresponds to the data for the healthcare record; and

storing the data for the healthcare record in association with the new indexing tag.

15. The system of claim 14 , wherein the operations comprise:

encoding the new indexing tag with the computing rule specific to the source-side system; and

generating, by the collection-side system, a second, different source-specific identifier based on the new indexing tag that was encoded with the computing rule.

16. The system of claim 11 , wherein the respective data for each of the first healthcare record and the second healthcare record includes one or more hashed tokens and determining the match comprises, determining a match between:

a first hashed token of the first healthcare record; and

a second hashed token for second healthcare record.

17. The system of claim 16 , wherein the operations comprise:

19. The system of claim 18 , wherein encoding the indexing tag comprises:

linking, at the collection-side system, de-identified data corresponding to the first healthcare record with de-identified data corresponding to the second healthcare record.

20. One or more non-transitory machine-readable storage devices storing instructions that are executable by one or more processing devices to cause performance of operations comprising:

determining, by a collection-side system, a match between:
