Abstract

A method and apparatus are provided for verification of the identity of a patient undergoing treatment administered by a medical treatment practitioner in a treatment room. An identifying element such as patient chart or patient photograph is provided for the patient which includes a patient identifier, e.g., a barcode, capable of being read by a reader device located within the treatment room. In use, the patient identifier is read by the reader device in the treatment room and a characteristic audio signal, previously assigned to the patient and known to the patient, is generated in response to the reading of the identifying element when there is a match between the patient identifier and a stored identifier for the patient. Treatment of the patient is at least temporarily withheld if any audio signal generated in response to reading of the patient identifier by the reader device is not the characteristic audio signal assigned to the patient. A special patient chart with a removable identifier can be used. A billing method which may involve the scanning step is also provided.

Claims

1. A method of verification of an identity of a patient, said method comprising:

scanning a patient identifier which identifies the patient to be treated; and

2. A method according to claim 1, wherein the audio signal is known to at least one of (i) the patient and (ii) an authorized caregiver for the patient.

3. A method according to claim 1 wherein the patient is undergoing medical treatment and the method further comprises at least temporarily withholding treatment of the patient if any audio signal generated in response to the scanning of the patient identifier is not the characteristic audio signal assigned to the patient.

4. A method according to claim 1 wherein the patient is a newborn baby and the scanning is carried out to ascertain whether the newborn baby may properly be removed from its current location.

5. A method according to claim 4 wherein an approved caregiver for the baby is assigned a badge including an identifier and the badge must also be scanned by the caregiver before the baby can properly be removed by the caregiver from said current location.

6. A method according to claim 4 wherein the patient identifier is carried by a name card on a bassinet for the baby.

7. A method according to claim 6 wherein the patient identifier is also carried by an identification band worn by the baby.

8. A method according to claim 1 wherein at least one further identifier, in addition to said patient identifier, is scanned for a match and said characteristic audio signal is generated only after a match is found in each instance that an identifier is scanned.

9. A method according to claim 8 wherein said characteristic audio signal is generated only when a match is found in each instance and only when the matches occur in a predetermined sequence.

10. A method according to claim 1 wherein, in addition to said scanning of the patient identifier, a caregiver identifier is scanned to determine whether the caregiver identifier is that of an authorized caregiver for the patient and a check sheet identifier is scanned to determine whether the check sheet is that of the patient, and wherein said characteristic audio signal is generated only after a match is provided in every instance.

11. A method according to claim 10 wherein said characteristic audio signal is generated only when the identifiers are scanned in a predetermined sequence.

12. A method according to claim 10 wherein a medication identifier associated with a medication about to be given to the patient is scanned to determine whether the medication is that intended for the patient and a further, matching characteristic audio signal is generated when there is a match.

13. A method according to claim 1 wherein the patient identifier is carried by a medication container for medication for the patient.

14. A method according to claim 13 wherein the patient identifier is also carried by a medication chart on which a physician first writes an order for the medication and both the medication container and the medication chart are scanned to determine whether said characteristic audio signal is generated in response thereto.

15. A method according to claim 1 wherein said scanning takes place in a patient dwelling and said patient identifier is carried by a container for a medication which is to be taken by the patient and which is prepared by a pharmacy.

16. A method according to claim 15 wherein a prescription for the medication, including the name of the patient, is initially written by a physician for the patient, wherein the prescription is received by the pharmacy, and wherein the pharmacy determines the corresponding scannable patient identifier assigned to the patient and dispenses the medication in said container carrying said patient identifier.

17. A method according to claim 1 wherein said scanning of said patient identifier comprises scanning of a medical device for delivering a medication to the patient.

18. A method according to claim 17 wherein said medical device comprises a syringe.

19. A method according to claim 1 wherein said patient identifier is carried by a label produced by the caregiver.

20. A method according to claim 19 wherein the caregiver initially dispenses a plurality of identical patient identifier carrying labels at the same time.

21. A method according to claim 20 wherein said method is used in chemotherapy treatment of the patient and said labels are applied to container for all drugs used in the chemotherapy treatment, to all syringes used in the chemotherapy treatment and to at least one patient identification member.

22. A method according to claim 1 wherein said scanning of patient identifier comprises scanning of a patient identifying member selected from the group consisting of a patient photograph, a patient treatment chart, a patient identification card and an identification band worn by the patient.

23. A method according to claim 22 wherein at least two of the patient identifier members of said group are separately scanned.

24. A method according to claim 1 wherein said scanning is carried out using a scanning device selected from the group consisting of a coded marking scanner, a retinal scanner, a fingerprint scanner, an iris scanner and a scanner for a subcutaneous microchip.

25. A method according to claim 24 wherein said patient identifier comprises a barcode and scanning of said barcode is carried out using a coded marking scanner comprising a barcode reader.

26. A method according to claim 1 wherein said characteristic audio signal comprises a non-verbal sound pattern.

27. A method according to claim 26 wherein said non-verbal sound pattern comprises a three tone chord.

28. A method according to claim 27 wherein the duration of said chord is about 2 to 3 seconds.

29. A method according to claim 27 wherein the chord is generated at two different times, in close sequence, from two spaced locations and the duration of said chord is about ½

to 2 seconds.

30. A method according to claim 1 wherein scanning of the patient identifier comprises scanning two different identification members carrying the patient identifier and results in the generation of two separate matching characteristic audio signals at two different spaced apart locations in a treatment room when the patient identifiers carried by the two members match said stored patient identifier.

31. A method according to claim 30 wherein the two patient identifiers are scanned by two different separate scanning devices spaced apart in the treatment room.
