Abstract

Certain embodiments of the present invention provide systems and methods for retrieving and re-identifying patient data. Patient data may be re-identified by retrieving an encrypted or abstracted patient identifier. The identifier is used to retrieve a patient identifier associated with patient identification information. Patient identification information may be inserted into a file, such as a report or other document, at a local computer or web portal for access by an authorized user. A system includes a data storage storing patient data. The patient data includes an encoded patient identifier and an unencoded patient identifier. The system includes a workstation or other processor having a viewing application capable of viewing patient data in a file including the encoded patient identifier. The workstation invokes a procedure to replace the encoded patient identifier in the file at the workstation with the corresponding unencoded patient identifier using the data storage.

Claims

1. A method for localized re-identification of patient data in an authorized environment, said method comprising:

retrieving, within an authorized environment, an encrypted patient identifier from a file;

locating a patient identifier associated with patient identification information using said encrypted patient identifier; and

inserting, within an authorized environment, said patient identification information into said file.

2. The method of claim 1, further comprising downloading said file to a workstation via a web service.

3. The method of claim 1, wherein said locating step further comprises locating said patient identifier associated with patient identification information in a database using said encrypted patient identifier.

4. The method of claim 1, wherein said file comprises a report of patients meeting a criterion, wherein said patients are anonymous in said report.

5. The method of claim 1, wherein said authorized environment comprises an authorized processor.

6. The method of claim 1, further comprising:

modifying said file; and

automatically uploading said file from said authorized environment to a data warehouse at a predetermined schedule.

7. The method of claim 1, further comprising:

modifying said document with said inserted patient identification information;

replacing said patient identification information with said encrypted patient identifier; and

saving said file in a database.

8. The method of claim 1, further comprising authenticating a user to re-identify said patient data.

9. A patient re-identification system, said system comprising:

a data storage storing patient data, wherein patient data includes an encoded patient identifier and a patient identifier, said encoded patient identifier corresponding to said patient identifier; and

a processor configured to connect with said data storage, said processor including a viewing application capable of viewing patient data in a file including said encoded patient identifier,

wherein said processor invokes a procedure to replace said encoded patient identifier in said file with said corresponding patient identifier using said data storage, and

wherein said replacement of said encoded patient data with said corresponding patient identifier occurs via said processor.

10. The system of claim 9, further comprising a web service configured to download said file to an authorized environment including said processor.

11. The system of claim 9, wherein said file comprises a report of patients meeting a criterion, wherein said patients are anonymous in said report.

12. The system of claim 9, wherein said file is modified using said processor and automatically uploaded using said processor to said data storage at a predetermined schedule.

13. The system of claim 9, wherein said procedure is incorporated in a viewing application executed using said processor, said viewing application configured to view said file, said procedure interfacing between said viewing application and said data storage.

14. The system of claim 9, wherein said processor comprises a processor in an environment authorized to view patient identification data.

15. At least one computer-readable medium including a set of instructions for execution on a computer, said set of instructions comprising:

a data store including patient-related data, said patient-related data including at least one encrypted patient identifier and at least one unencrypted patient identifier, said patient-related data searchable by said at least one encrypted patient identifier and said at least one unencrypted patient identifier;

a viewing application configured to view a file including patient data in an authorized environment; and

a re-identification routine triggered via said viewing application, said re-identification routine selecting an encrypted patient identifier in said file and matching said encrypted patient identifier in said file with one of said at least one encrypted patient identifier in said data store, said re-identification routine locating an unencrypted patient identifier corresponding with said encrypted patient identifier and inserting said unencrypted patient identifier into said file in said authorized environment.

16. The set of instructions of claim 15, wherein said viewing application automatically uploads said report from said authorized environment to said data store at a predetermined schedule.

17. The set of instructions of claim 15, further comprising a de-identification routine for replacing an unencrypted patient identifier with a corresponding encrypted patient identifier.

18. The set of instructions of claim 15, wherein said file comprises a report of patients meeting a criterion, wherein said patients are anonymous in said report.

19. The set of instructions of claim 15, wherein said viewing application comprises a web-based application.

20. The set of instructions of claim 15, wherein said data store comprises an electronic medical record data storage.
