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 to which a medical treatment is to be delivered, said method comprising:

scanning a patient identifier on an item associated with the medical treatment to be delivered to the patient and placed on the item by a patient caregiver for the patient to which the medical treatment is to be delivered, said patient identifier identifying the patient to which the medical treatment is to be delivered;

wherein a characteristic audio signal, previously assigned to the particular individual patient, is generated in response to scanning of the patient identifier; and

wherein the caregiver verifies the characteristic audio signal when the characteristic audio signal is generated.

2. A method according to claim 1, wherein the patient also verifies the characteristic audio signal when the characteristic audio signal is generated.

3. A method according to claim 1 wherein the caregiver is a radiation therapist, the medical treatment to be delivered comprises radiation therapy, and said item comprises a patient treatment chart.

4. A method according to claim 1 wherein at least one further item carrying a patient identifier and associated with the delivery of the medical treatment to be delivered is scanned.

5. A method according to claim 4 wherein the first-mentioned item and the at least one further item must be scanned in a predetermined sequence in order for said characteristic audio signal to be generated.

6. A method according to claim 1 further comprising scanning a further item carrying a patient identifier and generating said characteristic audio signal in response to the scanning of said further item.

7. A method according to claim 6 wherein both the first-mentioned item and the further item must be scanned in sequence in order for said characteristic audio signal to be generated.

8. A method according to claim 1 wherein the item comprises a medication container.

9. A method according to claim 8 wherein both the medication container and a patient chart must be scanned in a predetermined sequence in order for said characteristic audio signal to be generated.

10. A method of verification of an identity of a patient undergoing radiation treatment administered by a radiation therapist in a treatment room, said method comprising:

scanning a patient identifier on an item associated with the radiation treatment to be delivered to the patient in the treatment room, said patient identifier identifying the patient to which the medical treatment is to be delivered;

generating a characteristic audio signal, previously assigned to the particular individual patient, in response to scanning of the patient identifier; and

verifying the characteristic audio signal when the characteristic audio signal is generated.

11. A method according to claim 10, wherein the radiation therapist verifies the characteristic audio signal when the characteristic audio signal is generated.

12. A method according to claim 10 wherein said scanning takes place in the treatment room.

13. A method according to claim 10 wherein said item comprises a patient treatment chart.

14. A method according to claim 13 wherein a further item is scanned and said characteristic audio signal is generated only when both of said items are scanned.

15. A method according to claim 14 wherein said characteristic audio signal is generated only when both of said items are scanned in predetermined sequence.

16. A method of verification of an identity of a patient to which radiation treatment is to be delivered by a radiation treatment caregiver, said method comprising:

scanning a patient identifier on a patient treatment chart associated with the radiation treatment to be delivered to the patient, said patient identifier identifying the patient to which the radiation treatment is to be delivered;

generating a characteristic audio signal, previously assigned to the particular individual patient, in response to scanning of the patient identifier; and

verifying the characteristic audio signal when the characteristic audio signal is generated.

17. A method according to claim 16, wherein the radiation treatment caregiver verifies the characteristic audio signal when the characteristic audio signal is generated.

18. A method according to claim 17 wherein the treatment chart has a patient photograph associated therewith.

19. A method according to claim 16 wherein a further item is scanned and said characteristic audio signal is generated only when both of said items are scanned.

20. A method according to claim 19 wherein said characteristic audio signal is generated only when both of said items are scanned in predetermined sequence.

21. A method of verification of an identity of a patient to which a medical treatment is to be delivered, said method comprising:

entering a patient identifier for an item associated with a medical treatment to be delivered to a patient to be treated, said identifier identifying the patient to which the medical treatment is to be delivered; and

causing reading, at a later time, of the patient identifier entered for the item associated with the medical treatment to be delivered to the patient;

wherein a characteristic audio signal, to the particular individual patient, is generated in response to reading of the patient identifier; and

wherein a caregiver verifies the characteristic audio signal when the characteristic audio signal is generated.

22. A method according to claim 21 wherein the patient also verifies the characteristic audio signal when the characteristic audio signal is generated.

23. A method according to claim 21 wherein the item is a patient record.

24. A method according to claim 21 wherein the caregiver is a radiation therapist, the medical treatment to be delivered comprises radiation therapy, and said item comprises a patient treatment chart.

25. A method according to claim 21 wherein a patient identifier is entered for at least one further item associated with the delivery of the medical treatment to be delivered;

and

wherein the patient identifier for the first-mentioned item and for at least one further item must be read in a predetermined sequence in order for said characteristic audio signal to be generated.
