Abstract

A context information processing system used for accessing medical data includes an acquisition processor for acquiring configuration information indicating a type of a particular patient identification tag reader device of a plurality of different types of tag reader device and a format of patient identification data used by the particular patient identification tag reader device. An interpreter processes patient identification data received from the particular patient identification tag reader device using the received configuration information to provide a particular patient identifier. A context processor updates a record indicating that a current patient context, including a patient identifier, is compatible with the particular patient identifier.

Claims

1. A context information processing system used for accessing medical data, comprising:

an acquisition processor for acquiring configuration information indicating a type of a particular patient identification tag reader device of a plurality of different types of tag reader device and a format of patient identification data used by said particular patient identification tag reader device;

an interpreter for processing patient identification data received from said particular patient identification tag reader device using said received configuration information to provide a particular patient identifier; and

a context processor for updating a record indicating a current patient context comprising a patient identifier to be compatible with said particular patient identifier.

2. A system according to claim 1, wherein:

said context processor updates a centralized context repository containing said record; and

said record indicating said current patient context is accessible by a plurality of different executable applications.

3. A system according to claim 2, wherein said plurality of different executable applications intermittently poll said record indicating said current patient context to identify that said current patient context has changed.

4. A system according to claim 2, wherein said centralized context repository containing said record comprises a repository used by an HL7 compatible Global Session Manager (GSM) application.

5. A system according to claim 1, wherein said context processor initiates generation of a message to an executable application indicating at least one of, (a) said current patient context has changed and (b) said current patient context comprising said patient identifier compatible with said particular patient identifier.

6. A system according to claim 1, wherein said interpreter processes patient encounter identification data received from said particular patient identification tag reader device using said received configuration information to provide a particular patient identifier.

7. A system according to claim 1, wherein:

said configuration information comprises metadata identifying a location of patient identification data in said data received from said particular patient identification tag reader device; and

said plurality of different types of tag reader device comprise at least two of;

(a) an RFID tag compatible reader device, (b) a bar code tag compatible reader device, and (c) a wireless tag compatible reader device.

8. A system according to claim 7, wherein said interpreter parses said patient identification data received from said particular patient identification tag reader device to extract information comprising said particular patient identifier using said metadata identifying said location.

9. A system according to claim 1, wherein said configuration information comprises metadata identifying a location of patient encounter identification data in said data received from said particular patient identification tag reader device.

10. A system according to claim 1, further comprising:

a command processor for incorporating said particular patient identifier in an application specific information access request to obtain medical information concerning said particular patient and initiating display of an image including medical information of said particular patient.

11. A system according to claim 1, wherein said application specific information access request employs a URL.

12. A system according to claim 1, further comprising a display processor for initiating generation of data representing a display image enabling user entry of said configuration information.

13. A medical information access system, comprising:

a user accessible workstation adapted to receive raw data from an identification device;

a repository of metadata, the metadata comprising;

information regarding a method of raw data transfer from the identification device to the workstation, and

information regarding a structure of the raw data transferred from the identification device to the workstation; and

an interpreter, the interpreter residing within the workstation and being adapted to receive the metadata, the interpreter also being adapted to receive raw data from the identification device, the interpreter thereafter selecting a raw data decoding protocol based on the metadata received by the interpreter.

14. The medical information system of claim 13 wherein the metadata contains information indicating to the interpreter that a particular type of a patient identification tag reader device is connected to the workstation.

15. The medical information system of claim 14 wherein the metadata includes information indicating to the interpreter a format of patient identification data used by said particular patient identification tag reader device that is connected to the workstation.

16. The medical information system of claim 15 further comprising a context processor for updating a record indicating that a current patient context comprising a patient identifier is compatible with a particular patient identifier.

17. The medical information system of claim 16, wherein said context processor updates a centralized context repository containing said record.

18. A method of accessing and processing medical identification data, comprising:

interconnecting a workstation to a device adapted to scan an identification tag, the workstation subsequently reading raw data from the device adapted to scan an identification tag;

acquiring first information regarding a method of raw data transfer from the identification device to the workstation from a repository of said first information;

acquiring second information regarding a structure of the raw data transferred from the device to the workstation from a repository of said second information;

selecting a raw data decoding protocol based on the first and second acquired information; and

decoding the raw data using the selected raw data decoding protocol.

19. The method of claim 18, further comprising formulating an XML document derived from the decoded raw data.

20. The method of claim 19, further comprising identifying a particular patient identifier contained within said XML document.
