Abstract

A network for mediating the peer-to-peer transfer of digital patient medical data includes a plurality of distributed agents each associated with a health care provider and connected to a central system. Periodically the agents collect local information relating to patient medical files and/or data streams, for example diagnostic images and associated reports, and process that information into metadata files acting as pointers to the original files. The metadata files are transmitted to the central system where they are parsed and the attributes are stored on the central system in patient records with records from the same patient grouped together whenever possible. Registered users can search the central system, even in the absence of a unique identifier, to identify patient records pointing to the remote patient medical files. Upon finding a patient medical file, the invention provides a streamlined process for communicating access authorization from the patient to the hospital or facility storing the medical files. Once patient authorization is received, secure processes are provided for transferring the data in its entirety to or for viewing by the user in a peer-to-peer fashion.

Claims

1. A method operable on a computer for managing distributed medical data, comprising the steps of:

identifying, by an agent computer, a patient medical file containing digital medical data relating to a patient;

creating, by the agent computer, a metadata file containing attributes relating to the contents of the patient medical file and the location of the patient medical file;

transmitting, by the agent computer, the metadata file to a central computer;

the central computer determining if the metadata file matches any of a plurality of existing database entries in a database relating to patients, each of the existing database entries including attributes relating to a remotely located patient medical file including attributes relating to the contents of the remotely located patient medical file and attributes relating to the location of the remotely located patient medical file; and

if the metadata file matches an existing database entry, the central computer storing data from the metadata file in the existing database entry;

otherwise, the central computer creating a new database entry and storing data from the metadata file in the new database entry.

2. A method in accordance with claim 1 wherein:

the metadata file further includes attributes relating to the identity of the patient; and

the determining step further includes determining if attributes in the metadata file relating to the identity of the patient match attributes in the database relating to patients.

3. A method in accordance with claim 1 wherein the identifying step includes operating a software broker to communicate with a medical information system.

4. A method in accordance with claim 3 further comprising the software broker retrieving information from the medical information system.

5. A method in accordance with claim 3 further comprising the medical information system transmitting information to the software broker.

6. A method in accordance with claim 1 wherein the step of creating a metadata file includes the steps of:

parsing the patient medical file to identify selected attributes; and

storing the selected attributes in the metadata file.

7. A method in accordance with claim 1 wherein the transmitting step includes securely transmitting the metadata file to the central computer over a private dedicated network.

8. A method in accordance with claim 1 wherein the transmitting step includes securely transmitting the metadata file to the central computer over a local and/or wide area network.

9. A method in accordance with claim 1 wherein the step of determining includes the steps of:

parsing the metadata file to extract the attributes contained therein; and

determining if at least one attribute extracted from the metadata data file matches a corresponding attribute in any of the existing database entries.

10. A method in accordance with claim 1 and further including the steps of:

determining, on the central computer, if the metadata file relates to a new patient medical file; and

creating, if the metadata file relates to a new patient medical file, a new database entry for a new patient on the central computer, the new database entry for the new patient including data from the metadata file.

11. A method in accordance with claim 1 wherein the steps of creating the new database entry and storing data from the metadata file include the steps of:

parsing the metadata file to extract selected attributes;

processing the selected attributes to standardized formats; and

storing the processed selected attributes in the new database entry.

12. A method in accordance with claim 1 and further including the step of, if the metadata file relates to an existing database entry for a patient in the database, creating a new database entry including additional patient data for said patient in the database.

13. A method in accordance with claim 1, wherein the content attributes comprise a unique study identifier, an institution identifier, and a patient identifier.

14. A method in accordance with claim 1, wherein the content attributes comprise descriptive information of digital medical records of a patient.

25. A system in accordance with claim 3 wherein the steps of creating the new database entry and storing data from the metadata file include the steps of:

parsing the metadata file to extract selected attributes;

processing the selected attributes to standardized formats; and

storing the processed selected attributes in the new database entry.

26. A system in accordance with claim 3 and further including the step of, if the metadata file relates to an existing database entry for a patient in the database, creating a new database entry including additional patient data for said patient in the database.

15. A system for managing distributed medical data, comprising:

an agent computer comprising a processor and a memory, the memory storing instructions for controlling the operation of the agent computer; and

a central computer comprising a processor and a memory, the memory storing instructions for controlling the operation of the central computer;

the agent computer operative to perform the steps of;

identifying a patient medical file containing digital medical data relating to a patient;

creating a metadata file containing attributes relating to the contents of the patient medical file and the location of the patient medical file;

transmitting the metadata file to the central computer; and

the central computer operative to perform the steps of;

determining if the metadata file matches any of a plurality of existing database entries in a database relating to patients, each of the existing database entries including attributes relating to a remotely located patient medical file including attributes relating to the contents of the remotely located patient medical file and attributes relating to the location of the remotely located patient medical file; and

if the metadata file matches an existing database entry, storing data from the metadata file in the existing database entry;

otherwise, creating a new database entry and storing data from the metadata file in the new database entry.

16. A system in accordance with claim 15 wherein:

the metadata file further includes attributes relating to the identity of the patient; and

the determining step further includes determining if attributes in the metadata file relating to the identity of the patient match attributes in the database relating to patients.

17. A system in accordance with claim 15 wherein the agent computer includes a software broker that communicates with a medical information system in the identifying step.

18. A system in accordance with claim 17 wherein the software broker retrieves information from the medical information system.

19. A system in accordance with claim 17 wherein the medical information system transmits information to the software broker.

20. A system in accordance with claim 15 wherein the step of creating a metadata file includes the steps of:
