Abstract

A system and method of confirming administration of medication in a clinical trial is provided. The method comprises the steps of receiving information identifying a particular medication prescription regimen in accordance with the clinical trial, determining one or more procedures for administering such prescription regimen and identifying one or more activity sequences associated with such procedures. Activity sequences of actual administration of such prescription regimen are captured and then compared to the identified activity sequences to determine differences therebetween. A notice is provided if differences are determined.

storing the captured video activity sequences to a non-transitory computer readable storage medium;

comparing, by a computer processor, the stored video activity sequences to the predefined one or more identifiable gestures indicative of proper medication administration;

determining, from the comparison, differences between the stored video activity sequences and the predefined one or more identifiable gestures, wherein the differences indicate that the medication has not been properly administered;

responsive to determining the differences, providing, on the display of the local device, one or more further instruction prompts that further direct current performance of the one or more predefined identifiable gestures indicative of proper medication administration;

capturing, by the video capture device, second video activity sequences of the user following the one or more further instruction prompts to administer the medication during the current medication administration;

storing the captured second video activity sequences to the non-transitory computer readable storage medium;

comparing, by the computer processor, the stored second video activity sequences to the predefined one or more identifiable gestures indicative of proper medication administration; and

determining, by the computer processor, that the stored second video activity sequences are sufficiently similar to the predefined one or more identifiable gestures, thus confirming proper administration of the medication.

2. The method of claim 1, wherein the prescription regimen is provided by a healthcare provider.

3. The method of claim 1, further comprising retrieving the prescription regimen and the predefined one or more identifiable gestures indicative of proper medication administration from a medical database.

4. The method of claim 1, further comprising performing a statistical analysis of the differences between the stored video activity sequences and the predefined one or more identifiable gestures.

5. The method of claim 1, further comprising:

retrieving medical history information of the user to receive the medication to be administered; and

confirming, from the retrieved medical history information, that the medication to be administered is safe for the patient.

6. The method of claim 1, further comprising:

before capturing the video activity sequences, determining the identity of a particular medication to be used in the administration of the medication;

determining, by the computer processor, that the identity of the particular medication is not the same medication associated with the prescription regimen; and

issuing a warning responsive to determining that the identity of the particular medication is not the same medication associated with the prescription regimen.

7. The method of claim 1, comprising:

capturing, by the video capture device, a plurality of video activity sequences of the user following the one or more instruction prompts during a plurality of different medication administration sessions;

transmitting the captured video activity sequences from the plurality of different medication administration sessions to a remote server location;

further analyzing, by a computer processor of the remove server location, the plurality of captured video activity sequences by comparing each captured video activity sequence, of the plurality of captured video activity sequences, to the predefined one or more identifiable gestures to determine differences therebetween, thereby automatically determining that one or more of the predefined one or more identifiable gestures have been improperly performed by the user across one or more of the multiple medication administration sessions; and

providing an analysis of adherence to the particular prescription regimen based on the comparison of each captured video activity sequence, of the plurality of captured video activity sequences, to the predefined one or more identifiable gestures.

8. The method of claim 7, further comprising providing modified instructions directing performance of the one or more predefined identifiable gestures indicative of proper medication administration to a medication administrator in accordance with the provided analysis.

9. The method of claim 1, wherein the computer processor for performing the steps of comparing is located remote to the local device.

10. The method of claim 1, wherein the notice comprises additional instructions via the display of the local device to a patient receiving the medication according to the medication administration procedure.

11. A system for confirming administration of a medication, comprising:

an authentication apparatus operable to authenticate a healthcare provider;

an input device operable to receive information identifying a particular medication prescription regimen from the authenticated healthcare provider;

a storage device operable to store prescription administration information associated with the identified medication prescription regimen, a predefined set of one or more identifiable gestures indicative of proper administration of the medication in accordance with which the prescription regimen is to be administered, and one or more instruction prompts directing performance of the one or more predefined identifiable gestures indicative of proper medication administration;

a video capture device;

an audio and/or video output device operable to output the one or more instruction prompts directing performance of the one or more predefined identifiable gestures indicative of proper medication administration; and

a processor operable to perform operations comprising;

capturing, from the video capture device, video activity sequences of a user administering the medication by following the one or more instruction prompts directing performance of the one or more predefined identifiable gestures indicative of proper medication administration;

storing the captured video activity sequences to the storage device;

comparing the captured video activity sequences to the one or more predefined identifiable gestures indicative of proper medication administration;

determining that the stored captured video activity sequences are different from the one or more predefined identifiable gestures indicative of proper medication administration, indicating that administration of the medication has not been properly performed;

responsive to determining that the stored captured video activity sequences are different from the one or more predefined identifiable gestures, causing the audio and/or video output device to output one or more further instruction prompts for further directing performance of the one or more predefined identifiable gestures indicative of proper medication administration during a current medication administration session;

capturing, from the video capture device, second video activity sequences of the user administering the medication by following the one or more further instruction prompts;

storing the second captured video sequences to the storage device;

comparing the stored second video activity sequences to the one or more predefined identifiable gestures indicative of proper medication administration; and

determining that stored second captured video sequences are sufficiently similar to the one or more predefined identifiable gestures, indicating that proper medication administration was successful.

12. The system of claim 11, wherein the processor is located remote from the video capture device.

13. The system of claim 11, wherein the video capture device is further operable to capture images of a particular medication to allow identification thereof.

14. A method of confirming proper administration of medication, comprising:

authenticating a prescribing health care provider;

receiving information identifying a particular medication prescription regimen from the authenticated health care provider;
