Abstract

Systems and methods are disclosed that provide smart alerts to users, e.g., alerts to users about diabetic states that are only provided when it makes sense to do so, e.g., when the system can predict or estimate that the user is not already cognitively aware of their current condition, e.g., particularly where the current condition is a diabetic state warranting attention. In this way, the alert or alarm is personalized and made particularly effective for that user. Such systems and methods still alert the user when action is necessary, e.g., a bolus or temporary basal rate change, or provide a response to a missed bolus or a need for correction, but do not alert when action is unnecessary, e.g., if the user is already estimated or predicted to be cognitively aware of the diabetic state warranting attention, or if corrective action was already taken.

Claims

1. A non-transitory computer readable medium, comprising instructions for causing a computing environment to perform a method of dynamically adjusting or tuning user alerts based on a cognitive awareness determination, thereby providing data relevant to treatment of a diabetic state warranting attention, the method comprising steps of:

identifying a current or future diabetic state warranting attention, the identifying based at least partially on a glucose concentration value;

estimating or predicting a cognitive awareness of a user of the identified current or future diabetic state warranting attention, wherein the estimating or predicting the cognitive awareness is based on an established pattern of behavior of the user; and

if the result of the estimating or predicting is that the user is cognitively unaware of the identified current or future diabetic state warranting attention, then alerting the user with a user prompt on a user interface of a monitoring device, the user prompt indicating the diabetic state warranting attention,

whereby the user is only alerted of the diabetic state warranting attention if and at a time that the user is unaware of the diabetic state warranting attention and that the notification is effective for the user; and

wherein the alerting the user with the user prompt on the user interface of the monitoring device includes, if the user ignores a first alerting, then causing a prompt on a second user interface of the monitoring device or causing a prompt on a second user interface of a second device.

2. The medium of claim 1, wherein the monitoring device is a mobile cellular device, and wherein the second user interface includes an audio channel.

3. The medium of claim 2, wherein the user prompt is an audible prompt and is played through the audio channel.

4. The medium of claim 1, wherein the monitoring device is a mobile cellular device, and wherein the second user interface includes a vibratory, haptic, or tactile rendering system.

5. The medium of claim 4, wherein the user prompt is a vibratory prompt and is played through the vibratory, haptic, or tactile rendering system.

6. The medium of claim 5, wherein the second user interface includes an audio channel, wherein the user prompt is an audible prompt and is played through the audio channel, and wherein the vibratory prompt is caused to be rendered if the audible prompt is not acknowledged by the user.

7. The medium of claim 1, wherein the second device is a medicament delivery device, and where the user prompt is audible or vibratory.

8. The medium of claim 1, wherein the alerting a user with a user prompt on a user interface of a monitoring device or on a second device includes rendering a haptic or vibratory signal.

9. The medium of claim 8, wherein the rendering is on the monitoring device.

10. The medium of claim 8, wherein the rendering is on the second device, the second device in signal communication with the monitoring device.

11. The medium of claim 10, wherein the monitoring device is a smart phone and the second device in signal communication with the monitoring device is a smart watch.

12. The medium of claim 8, wherein the rendering includes rendering the user prompt in a pattern, the pattern corresponding to the diabetic state warranting attention.

16. A system for providing smart alerts corresponding to diabetic states warranting user attention, comprising:

a CGM application running on a mobile device, the CGM application configured to receive data from a sensor on an at least periodic or occasional basis and to calibrate and display glucose concentration data in clinical units; and

a smart alerts application running as a subroutine within the CGM application or running as a parallel process with the CGM application on the mobile device and receiving data from the CGM application, the smart alerts application configured to perform the method contained on the medium of claim 1.

13. A non-transitory computer readable medium, comprising instructions for causing a computing environment to perform a method of safely reducing alerting of users to diabetic states that require attention, the method comprising steps of:

identifying a current or future diabetic state warranting attention, the

identifying based at least partially on a glucose concentration value;

determining if the identified diabetic state warranting attention is atypical for the user;

if a result of the determining is that the identified diabetic state is atypical for the user, then alerting the user with a user prompt on a user interface of a monitoring device, the user prompt indicating the diabetic state warranting attention,

whereby the user is only notified of the diabetic state warranting attention if the identified diabetic state is atypical for the user, wherein the identified diabetic state is atypical if it does not follow other patterns associated with the user.

14. The medium of claim 13, wherein the determining if the identified diabetic state warranting attention is atypical for the user includes determining if the identified diabetic state includes a glucose trace following a pattern that is not typical of other patterns associated with the user.

15. The medium of claim 13, wherein the determining if the identified diabetic state warranting attention is atypical for the user includes determining if the identified diabetic state includes a glucose trace following a trend that is not typical of other trends associated with the user.

17. A system for providing smart alerts corresponding to diabetic states warranting user attention, comprising:

a CGM application running on a mobile device, the CGM application configured to receive data from a sensor on an at least periodic or occasional basis and to calibrate and display glucose concentration data in clinical units; and

a smart alerts application running as a subroutine within the CGM application or running as a parallel process with the CGM application on the mobile device and receiving data from the CGM application, the smart alerts application configured to perform the method contained on the medium of claim 13.
