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.

First claim

What is claimed is:

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 the user of the identified current or future diabetic state warranting attention; 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 transmitting an indication of the diabetic state warranting attention to a medicament pump,
whereby the user is only treated for the diabetic state warranting attention if and at a time that the user is unaware of the diabetic state warranting attention.

2. The medium of claim 1 , wherein if the result of the estimating or predicting is that the user is not cognitively aware of the diabetic state warranting attention, then further comprising activating the medicament pump to provide a medicament bolus.

3. The medium of claim 2 , wherein the medicament bolus is a meal bolus of insulin.

4. The medium of claim 1 , if the result of the estimating or predicting is that the user is not cognitively aware of the diabetic state warranting attention, then further comprising activating the medicament pump to change a basal rate.

5. The medium of claim 1 , if the result of the estimating or predicting is that the user is not cognitively aware of the diabetic state warranting attention, then further comprising alerting a user with a user prompt on a user interface of a monitoring device, the user prompt indicating the diabetic state warranting attention.

6. The medium of claim 1 , further comprising determining if the medicament pump can treat the diabetic state warranting attention either fully or partially, and if so, then disabling an alert to the user, or not alerting the user, or altering the user prompt, respectively, as compared to a case where the medicament pump cannot treat the diabetic state.

7. 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 or the CGM application in signal communication with a medicament delivery device, the smart alerts application configured to perform the method contained on the medium of claim 1 .

8. A non-transitory computer readable medium, comprising instructions for causing a computing environment to perform a method of prompting a user about a diabetic state that warrants attention, the computing environment in signal communication with a medicament delivery device, the user prompt optimized for effectiveness to the user at least in part by being reduced in number, the user prompt providing data relevant to treatment of the 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;
performing a first estimating or predicting of a cognitive awareness of the user of the identified current or future diabetic state warranting attention;
if the result of the first estimating or predicting is that the user is cognitively unaware of the identified current or future diabetic state warranting attention, then performing a second estimating or predicting of a computer awareness of the medicament delivery device of the identified current or future diabetic state warranting attention;
if the result of the second estimating or predicting is that the medicament delivery device is 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 notified of the diabetic state warranting attention if and at a time that both the user and the medicament delivery device are unaware of the diabetic state warranting attention and that the notification is effective for the user.

9. The medium of claim 8 , wherein the method further comprises steps of determining if the medicament delivery device is capable of treating the identified current or future diabetic state warranting attention, and if the result of the determining is that the medicament delivery device is incapable of treating the identified diabetic state, then alerting the user with the user prompt.

10. The medium of claim 8 , wherein the current or future diabetic state includes hypoglycemia, and wherein the medicament delivery device is an insulin delivery device, and further comprising shutting off or reducing activity of the insulin delivery device based on the diabetic state of hypoglycemia.

11. The medium of claim 10 , wherein the shutting off or reducing activity occurs sooner in the case where the user is cognitively unaware of the hypoglycemia.

12. The medium of claim 8 , wherein the performing a first estimating or predicting is based at least partially on user interaction with the medicament delivery device.

13. 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 or the CGM application in signal communication with a medicament delivery device, the smart alerts application configured to perform the method contained on the medium of claim 8 .

14. 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 the user of the identified current or future diabetic state warranting attention, wherein the estimating or predicting includes recognizing one or more individualized patterns associated with the user;
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 a 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 diabeti
