Abstract

A method of verifying the identity of a dispensed pharmaceutical includes the steps of: reading identifying indicia on a pharmaceutical vial containing a dispensed pharmaceutical; determining the identity of a prescribed pharmaceutical called for by the identifying indicia; acquiring an image of the dispensed pharmaceutical through the vial; comparing the image of the dispensed pharmaceutical to data storage comprising image data associated with pharmaceuticals; acquiring spectral data for the dispensed pharmaceutical through the vial; comparing the spectral data of the dispensed pharmaceutical to data storage comprising spectral data associated with pharmaceuticals; and automatically determining whether the image and the spectral data of the dispensed pharmaceutical confirm that the dispensed pharmaceutical matches the prescribed pharmaceutical.

Claims

1. A method of verifying the identity of a dispensed pharmaceutical, comprising:

reading identifying indicia on a pharmaceutical vial containing a dispensed pharmaceutical;

comparing the identity of the prescribed pharmaceutical to data storage comprising data that indicates whether the prescribed pharmaceutical is one that can be positively distinguished by image and spectral analysis; and

responsive to the comparison of the identity of the prescribed pharmaceutical to data storage, either (a) rejecting the dispensed pharmaceutical when the comparison indicates that the prescribed pharmaceutical cannot be positively distinguished by image and spectral analysis, or (b) performing the following when the comparison indicates that the prescribed pharmaceutical can be positively distinguished by image and spectral analysis;

acquiring an image of the dispensed pharmaceutical through the vial;

comparing the image of the dispensed pharmaceutical to data storage comprising image data associated with pharmaceuticals;

acquiring spectral data for the dispensed pharmaceutical through the vial;

comparing the spectral data of the dispensed pharmaceutical to data storage comprising spectral data associated with pharmaceuticals; and

automatically determining whether the image and the spectral data of the dispensed pharmaceutical confirm that the dispensed pharmaceutical matches the prescribed pharmaceutical.

2. The method of claim 1, further comprising approving the dispensed pharmaceutical responsive to a determination that the image and the spectral data of the dispensed pharmaceutical confirm that the dispensed pharmaceutical matches the prescribed pharmaceutical.

3. The method of claim 2, wherein approving the dispensed pharmaceutical comprises stamping the vial with a stamp of approval.

4. The method of claim 2, further comprising:

collecting data associated with the approval of the dispensed pharmaceutical; and

storing the data associated with the approval of the dispensed pharmaceutical in data storage for future access.

5. The method of claim 1, further comprising rejecting the dispensed pharmaceutical responsive to a determination that the image and the spectral data of the dispensed pharmaceutical do not confirm that the dispensed pharmaceutical matches the prescribed pharmaceutical.

6. The method of claim 5, wherein rejecting the dispensed pharmaceutical comprises quarantining the pharmaceutical vial.

7. The method of claim 5, further comprising:

collecting data associated with the rejection of the dispensed pharmaceutical; and

storing the data associated with the rejection of the dispensed pharmaceutical in data storage for future access.

8. The method of claim 1, wherein comparing the image of the dispensed pharmaceutical comprises:

selecting from the data storage comprising image data associated with pharmaceuticals at least one visual attribute of the prescribed pharmaceutical; and

comparing the at least one visual attribute to the image of the dispensed pharmaceutical.

9. The method of claim 1, wherein comparing the spectral data of the dispensed pharmaceutical comprises determining whether the spectral data of the dispensed pharmaceutical uniquely matches spectral data associated with the prescribed pharmaceutical, the method further comprising, responsive to a determination that the spectral data of the dispensed pharmaceutical does not uniquely match the spectral data associated with the prescribed pharmaceutical:

selecting from the data storage comprising image data associated with pharmaceuticals at least one visual attribute of the prescribed pharmaceutical;

comparing the at least one visual attribute to the image of the dispensed pharmaceutical; and

automatically determining whether the image and the at least one visual attribute of the prescribed pharmaceutical confirm that the dispensed pharmaceutical uniquely matches the prescribed pharmaceutical.

10. The method of claim 1, wherein:

comparing the image of the dispensed pharmaceutical comprises;

selecting from the data storage comprising image data associated with pharmaceuticals at least one visual attribute of the prescribed pharmaceutical; and

comparing the at least one visual attribute to the image of the dispensed pharmaceutical; and

comparing the spectral data of the dispensed pharmaceutical comprises determining whether the spectral data of the dispensed pharmaceutical uniquely matches spectral data associated with the prescribed pharmaceutical, the method further comprising, responsive to a determination that the spectral data of the dispensed pharmaceutical does not uniquely match the spectral data associated with the prescribed pharmaceutical;

selecting from the data storage comprising image data associated with pharmaceuticals at least one additional visual attribute of the prescribed pharmaceutical;

comparing the at least one additional visual attribute to the image of the dispensed pharmaceutical; and

automatically determining whether the image and the at least one additional visual attribute of the prescribed pharmaceutical confirm that the dispensed pharmaceutical uniquely matches the prescribed pharmaceutical.

11. The method of claim 1, further comprising:

collecting at least one of image and spectral data associated with the dispensed pharmaceutical; and

storing the at least one of image and spectral data associated with the dispensed pharmaceutical in data storage for future access.

12. The method of claim 1, further comprising remotely updating at least one of the image data storage and the spectral data storage.

13. The method of claim 1, wherein the identifying indicia comprises a bar code.

14. A system for verification of dispensed pharmaceuticals, comprising:

an identification station configured to read identifying indicia on a pharmaceutical vial containing a dispensed pharmaceutical;

an image station configured to acquire an image of the dispensed pharmaceutical through the vial;

a spectroscopy station configured to acquire spectral data for the dispensed pharmaceutical through the vial; and

a controller associated with the identification, vision, and spectroscopy stations, wherein the controller is configured to;

receive the identifying indicia from the identification station;

automatically determine the identity of a prescribed pharmaceutical called for by the identifying indicia;

compare the identity of the prescribed pharmaceutical to data storage comprising data that indicates whether the prescribed pharmaceutical is one that can be positively distinguished by image and spectral analysis; and

responsive to the comparison of the identity of the prescribed pharmaceutical to data storage, either (a) reject the dispensed pharmaceutical when the comparison indicates that the prescribed pharmaceutical cannot be positively distinguished by image and spectral analysis, or (b) perform the following when the comparison indicates that the prescribed pharmaceutical can be positively distinguished by image and spectral analysis;

receive the image of the dispensed pharmaceutical from the image station;

compare the image of the dispensed pharmaceutical to data storage comprising image data associated with pharmaceuticals;
