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 safely reducing alerting of users to diabetic states that require attention, the method comprising:
identifying a current or future diabetic state warranting attention, the identifying based at least partially on a glucose concentration value;
determining a glucose trace associated with the current or future diabetic state, the glucose trace indicative of a pattern associated with the glucose response of the user and having a specific curve or signature characteristics including one or more of shape, width, Full width at half maximum (FWHM), time, slope, slope/time, and duration;
accessing historical diabetic state data describing at least one diabetic state previously experienced by a user, wherein the at least one diabetic state previously experienced by the user comprises a pattern identified based at least partially on one or more historical glucose concentration values associated with the user, the pattern comprising a set of glucose trace curve or signature characteristics including one or more of shape, width, Full width at half maximum (FWHM), time, slope, slope/time, and duration;
determining, based at least in part on the historical diabetic state data, that the identified diabetic state warranting attention is atypical for the user, comprising comparing the specific curve or signature characteristics of the glucose trace associated with the current or future diabetic state to the set of glucose trace curve or signature characteristics associated with the at least one diabetic state previously experienced by the user; and
responsive to the determining that the identified diabetic state warranting attention is atypical for the user, 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.

2. The medium of claim 1 , wherein the determining if the identified diabetic state 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.

3. The medium of claim 1 , wherein the determining if the identified diabetic state 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.

4. 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 .

5. A method of safely reducing alerting of users to diabetic states that require attention, the method comprising:
identifying a current diabetic state warranting attention, the identifying based at least partially on a glucose concentration value of a user;
determining a glucose trace associated with the current diabetic state, the glucose trace indicative of a pattern associated with the glucose response of the user and having a specific curve or signature characteristics including one or more of shape, width, Full width at half maximum (FWHM), time, slope, slope/time, and duration;
accessing historical diabetic state data describing at least one diabetic state previously experienced by the user, wherein the at least one diabetic state previously experienced by the user comprises a pattern identified based at least partially on one or more historical glucose concentration values associated with the user, the pattern comprising a set of glucose trace curve or signature characteristics including one or more of shape, width, Full width at half maximum (FWHM), time, slope, slope/time, and duration;
determining, based at least in part on the historical diabetic state data, whether the diabetic state warranting attention is atypical or not atypical, wherein a diabetic state warranting attention is not atypical if it was previously treated by the user through a user action without receiving an alert, wherein the determining comprises comparing the specific curve or signature characteristics of the glucose trace associated with the current diabetic state to the set of glucose trace curve or signature characteristics associated with the at least one diabetic state previously experienced by the user;
suppressing an alert to the user related to the diabetic state warranting attention when the identified diabetic state is determined to be not atypical; and
then alerting the user with a user prompt on a user interface of a monitoring device indicating the diabetic state warranting attention when the identified diabetic state is determined to be atypical.
