Abstract

The present invention relates to a system and method to manage the administration of medication to a patient. In particular, the system and method of the present invention maintains a database of medications to be taken by a patient. The database includes at least the medication name, dosage, and administration time or frequency of administration. In addition, the database may contain specific cautionary warnings and notices regarding the administration of the medication. The system and method monitors the medication schedule to determine the time that a particular medication should be administered. Once an administration time has been determined, a notification is provided to a patient or caregiver at the appropriate time indicating the particular medication to administer. The system and method then determines the identity of a medication chosen by the patient or caregiver to be administered, and compares this medication to the medication identified in the medication schedule. The system and method then determines whether the correct medication has been chosen by the patient or caregiver for administration, and reports the results.

Claims

1. A system for managing the administration of medication to a patient, the medication having a unique identity, the system comprising:

(a) an identification tag for identifying the medication selected to be administered to the patient; and

(b) a medication management unit, the medication management unit comprising a portable computing device and being capable of monitoring and assisting in maintaining compliance with a patient'"'"'s medication administration schedule, the medication management unit further comprising;

(i) an application program;

(ii) timing device to monitor and determine a time for the administration of the patient'"'"'s medication in accordance with the medication schedule;

(iii) a notification device for providing a notification that the medication needs to be administered;

(iv) a medication indicator for indicating the identity of the medication to be administered in accordance with the medication schedule;

(v) an I/O device for reading the medication identity from the identification tag associated a the selected medication;

(vi) a means for comparing the medication identity read from the identification tag to the medication identity from the medication indicator to determine if the correct medication was selected; and

(vii) a means for displaying the results of the comparison between the medication identity read from the identification tag and medication identity identified by the medication indicator.

2. The system of claim 1 wherein the identification tag is a bar code that stores the medication'"'"'s identification.

3. The system of claim 1 wherein the identification tag is a RFID tag that stores the medication'"'"'s identification in electronic format.

4. The system of claim 1 wherein the identification tag is a semiconductor chip that stores the medication'"'"'s identification in electronic format.

5. The system of claim 1 wherein the portable computing device is a hand held computer.

6. The system of claim 1 wherein the portable computing device is a programmable wrist watch.

7. The system of claim 1 wherein the timing device determines the time for the administration of the patient'"'"'s medication by monitoring actual calendar and clock time in real-time.

8. The system of claim 1 wherein the timing device determines the time for the administration of the patient'"'"'s medication by measuring a time interval from the last time the medication was actually administered.

9. The system of claim 1 wherein the notification is aural.

10. The system of claim 1 wherein the notification is visual.

11. The system of claim 1 wherein the notification is vibratory.

12. The system of claim 1 wherein the medication indicator is a display device providing a textual message.

13. The system of claim 1 wherein the I/O device is a bar code scanner.

14. The system of claim 1 wherein the I/O device is an RFID reader capable of powering and reading a RFID identification tag using radio frequency signals.

15. The system of claim 1 wherein the I/O device is a contactless reader capable of reading information from a microprocessor using radio frequency signals.

16. The system of claim 1 wherein the I/O device is an infrared transceiver capable of reading and transmitting infrared signals.

17. The system of claim 1 wherein the means for comparing the medication identity read from the identification tag to the medication identity identified by the medication indicator comprises software resident in the medication management unit.

18. The system of claim 1 wherein the means for displaying the similarity between the compared medication identity from the identification tag and the medication identity identified by the medication indicator comprises a graphical representation on a display panel.

19. The system of claim 1 wherein the means for displaying the similarity between the compared medication identity from the identification tag and the medication identity identified by the medication indicator comprises an aural notification through a speaker system.

20. The system of claim 1 wherein the means for displaying the similarity between the compared medication identity from the identification tag and the medication identity identified by the medication indicator comprises a textual message displayed on a display device.

21. The system for managing the administration of medication to a patient of claim 1 further comprising an interface to a pharmacist'"'"'s computer system.

22. The system of claim 21 wherein the interface comprises a data transfer cradle, electronically connected to the pharmacist'"'"'s computer system, for receiving the medication management unit.

23. The system of claim 21 wherein the interface comprises an infrared transceiver operatively connected to the pharmacist'"'"'s computer system, for communicating with the medication management unit through infrared signals.

24. The system of claim 21 wherein the interface comprises a light sensor operatively connected to the portable computing device for communicating with the pharmacist'"'"'s computer system through light-wave signals.
