Abstract

A method of verifying fulfillment of a prescription may include receiving an image of a personalized medication package associated with a patient, receiving a patient identifier associated with the patient, and using the patient identifier to identify a medication regimen for the patient. The method may include analyzing the image to identify at least one pill, and for each identified pill, determining one or more physical features of the pill, determining a location of the pill with respect to the personalized medication package, determining whether the determined location of the pill is correct based on the determined physical features and the medication regimen, and in response to determining that the determined location of the pill is not accurate, generating an alert.

sending an electronic message to a user.

9. The method of claim 1, wherein generating an alert comprises generating an alert comprising one or more of the following:

an indication that the determined location of the pill is not accurate;

the determined location; and

the determined physical features of the pill.

10. The method of claim 1, further comprising storing the received image for a period of time.

11. A method of verifying fulfillment of a prescription, the method comprising:

receiving, by a computing device, an image of a personalized medication package associated with a patient;

receiving, by the computing device, a patient identifier associated with the patient;

using the patient identifier to identify a medication regimen for the patient, wherein the medication regimen comprises one or more medications prescribed to the patient and, for each medication;

a physical description of the medication, and

one or more locations on the personalized medication package where the medication is located;

analyzing the image to identify one or more compartments of the personalized medication package;

for each identified compartment, determining whether a number of pills within the compartment is correct based on the medication regimen; and

in response to determining that the number of pills within the compartment is not correct, generating an alert.

12. The method of claim 11, wherein determining whether a number of pills within the compartment is correct based on the medication regimen comprises:

determining an actual number of pills within the compartment from the image;

determining an expected number of pills within the compartment by using the medication regimen to identify a number of pills of each medication having a location corresponding to the location of the compartment; and

determining that the number of pills within compartment is correct if the actual number of pills equals the expected number of pills.

13. The method of claim 11, wherein determining whether a number of pills within the compartment is correct based on the medication regimen comprises:

determining an actual number of pills within the compartment from the image;

determining an expected number of pills within the compartment by using the medication regimen to identify a number of pills of each medication having a location corresponding to the location of the compartment; and

determining that the number of pills within compartment is incorrect if the actual number of pills does not equal the expected number of pills.

14. A method of verifying fulfillment of a prescription, the method comprising:

receiving, by a computing device, an image of a personalized medication package associated with a patient;

receiving, by the computing device, a patient identifier associated with the patient;

using the patient identifier to identify a medication regimen for the patient, wherein the medication regimen comprises one or more medications prescribed to the patient and, for each medication;
