Abstract

Systems and methods are disclosed that employ several or numerous factors in the determination of a glycemic urgency index (GUI), which may be based on a measured blood glucose level as well as other factors. The other factors may include time derivatives of the glucose level and/or other factors, e.g., user-entered data, data measured by other sensors or received from a network source, or historical data. The GUI is then presented to the user in an interesting way, e.g., via a background color or other inconspicuous notifier, e.g., on a mobile device such as a smart phone. The GUI may also be employed in the triggering of actionable alerts and alarms on an electronic device for the user. The GUI, or another index calculated from combinations of the variables and parameters described, may further be employed to drive a medicament delivery device such as a pump.

Claims

1. A method of determining a user'"'"'s urgency state associated with a physiological condition, comprising:

a. determining an urgency index based on an analyte concentration and at least two variables selected from the group consisting of;

a first or second time derivative of the analyte concentration, a duration the analyte concentration has occupied a predetermined range, a duration the first or second time derivative of the analyte concentration has occupied a predetermined range, a past or future meal intake parameter entered by a user, or a past or future medicament parameter entered by a user or received from an integrated pump; and

b. storing the determined urgency index in a storage of a mobile device.

2. The method of claim 1, further comprising displaying or otherwise outputting an indication of the urgency index on a user interface of the mobile device.

3. The method of claim 2, wherein the displaying step further comprises overriding other applications or processes operating on the mobile device, such that the indication of the urgency index is displayed regardless of other running applications or processes.

4. The method of claim 2, wherein the displaying step is caused by a user action, the user action selected from the group consisting of:

handling the mobile device, unlocking the mobile device, or performing a swiping action on the mobile device.

5. The method of claim 1, wherein the indication of the urgency index is a rendered element.

6. The method of claim 5, wherein the rendered element includes a color.

7. The method of claim 5, wherein the rendered element includes an icon.

8. The method of claim 7, wherein a position, size, or color of the icon is based on the urgency index.

9. The method of claim 7, further comprising:

a. receiving an indication that a user has activated the icon; and

b. displaying additional information or an advanced output about the urgency index.

10. The method of claim 6, wherein the rendered element is rendered as at least a portion of a home screen or a background, native to an operating system of the mobile device.

11. The method of claim 1, wherein the analyte is glucose, the urgency index is a glycemic urgency index, and the medicament parameter corresponds to insulin.

12. The method of claim 11, further comprising rendering a series of elements on the user interface of the mobile device, the series of elements indicating past or predicted future values of glucose concentration.

13. The method of claim 2, wherein the indication of the urgency index includes an audible or visual alert rendered or sounded, respectively, on the mobile device.

14. The method of claim 1, further comprising displaying a prompt for a user to enter data, such that user data may be associated with the urgency index.

15. The method of claim 14, wherein the prompt for a user to enter data indicates a type of data, and wherein the type of data is selected from the group consisting of:

exercise or activity level, meal data, insulin data, stress or health data, or emotional data.

16. The method of claim 1, further comprising displaying at least one potential action a user may perform in response to the displayed indication of the urgency index.

17. The method of claim 2, wherein the indication includes an actionable alert.

18. The method of claim 2, wherein the displaying an indication includes displaying occupancy of a band, the band corresponding to a predetermined range of urgency index values.

19. The method of claim 1, further comprising transmitting the stored urgency index to an integrated pump.

20. The method of claim 1, further comprising transforming the stored urgency index to a pump action, and transmitting the pump action to an integrated pump.

21. An electronic device for monitoring data associated with a physiological condition, comprising:

a. a continuous analyte sensor, wherein the continuous analyte sensor is configured to substantially continuously measure the concentration of analyte in the host, and to provide continuous sensor data associated with the analyte concentration in the host; and

b. a processor module configured to determine an urgency index based on the measured concentration of the analyte in the host and at least two variables selected from the group consisting of;

a first or second time derivative of the analyte concentration, a duration the analyte concentration has occupied a predetermined range, a duration the first or second time derivative of the analyte concentration has occupied a predetermined range, a past or future meal intake parameter entered by a user, or a past or future medicament parameter entered by a user or received from an integrated pump, and to store the determined urgency index in a storage of a mobile device.

22. The device of claim 21, wherein the analyte is glucose.
