Abstract

Systems and methods are provided to provide guidance to a user regarding management of a physiologic condition such as diabetes. The determination may be based upon a patient glucose concentration data sensed by a glucose concentration sensor. A host state change associated with the host glucose concentration data may be determined. A guidance message based at least in part on the host state change may also be determined. The guidance message may be delivered through a user interface.

First claim

What is claimed is:

1. A system comprising:
a glucose concentration sensor configured to detect a host glucose concentration;
a communication circuit configured to receive the host glucose concentration from the glucose concentration sensor; and
a processor configured to:
receive host glucose concentration measurements from the communication circuit;
predict, using a machine learning model, a future occurrence of a host entering a second host state from a first host state, wherein the first host state is associated with a first glucose concentration profile and the second host state is associated with a second glucose concentration profile, wherein the machine learning model is trained using a training dataset including behavioral and physiological data associated with the host, wherein the behavioral and physiological data includes at least one of (i) heart rate data received from a heart rate sensor, (ii) respiration data received from a respiration sensor (iii) the host glucose concentration from the glucose concentration sensor, (iv) host motion data from a motion sensor, (v) posture data from a posture sensor, or (vi) acoustic data from an acoustic sensor, and wherein each of the first and second glucose concentration profiles corresponds to glucose levels and/or a glucose rate of change of the host over time in connection with a behavioral state or a physiological state of the host, wherein the first host state is a pre-sleep or a pre-exercise state, and wherein the second host state is a sleep or exercise state;
determine, during the pre-sleep or pre-exercise state, a guidance message based at least in part on the prediction of the future occurrence of the host entering the sleep or exercise state from the pre-sleep or pre-exercise state, respectively, the second glucose concentration profile associated with the sleep or exercise state, the behavioral and physiological data, and the physiological data including the host glucose concentration measurements; and
deliver, during the pre-sleep or pre-exercise state, the guidance message through a user interface.

2. The system of claim 1 , wherein the processor is further configured to determine that the future occurrence is atypical, and wherein determining of the guidance message is based at least in part on an atypicality of the future occurrence.

3. The system of claim 1 , wherein predicting the future occurrence of the host entering the second host state from the first host state comprises identifying a likely transition to the second host state, and wherein the second host state comprises an undesirable host state, and the guidance message is determined and delivered at a time such that the host can intervene to avoid the future occurrence of the host entering the second host state, wherein the time is during the pre-sleep or pre-exercise state.

4. The system of claim 1 , wherein the system includes a mobile device, the mobile device including the processor.

5. The system of claim 4 , wherein the mobile device includes the communication circuit, and the glucose concentration sensor includes a glucose concentration sensor communication circuit configured to communicate with the communication circuit.

6. The system of claim 5 , wherein the communication circuit includes a first wireless transceiver, and the glucose concentration sensor communication circuit includes a second wireless transceiver, and wherein the communication circuit and the glucose concentration sensor communication circuit communicate using a wireless communication protocol.

7. The system of claim 1 , further comprising an insulin delivery system.

8. The system of claim 1 , wherein the future occurrence of the host entering the second host state from the first host state is from a first disease state describing a first host disease stage to a second disease state indicating a second host disease stage, and wherein the processor is further configured to determine a second guidance message based at least in part on the second host disease stage.

9. A method comprising:
receiving, by a processor, host glucose concentration measurements from a communication circuit in communication with a glucose concentration sensor;
predicting, using a machine learning model executed by the processor, a future occurrence of a host entering a second host state from a first host state, wherein the first host state is associated with a first glucose concentration profile and the second host state is associated with a second glucose concentration profile, wherein the machine learning model is trained using a training dataset including behavioral and physiological data associated with the host, wherein the behavioral and physiological data includes at least one of (i) heart rate data received from a heart rate sensor, (ii) respiration data received from a respiration sensor (iii) the host glucose concentration from the glucose concentration sensor, (iv) host motion data from a motion sensor, (v) posture data from a posture sensor, or (vi) acoustic data from an acoustic sensor, and wherein each of the first and second glucose concentration profiles corresponds to glucose levels and/or a glucose rate of change of the host over time in connection with a behavioral state or a physiological state of the host, wherein the first host state is a pre-sleep or a pre-exercise state, and wherein the second host state is a sleep or exercise state;
determining, by the processor, during the pre-sleep or pre-exercise state, a guidance message based at least in part on the prediction of the future occurrence of the host entering the sleep or exercise state from the pre-sleep or pre-exercise state, respectively, the second glucose concentration profile associated with the sleep or exercise state, the behavioral and physiological data, and the physiological data including the host glucose concentration measurements; and
delivering, by the processor, during the pre-sleep or pre-exercise state, the guidance message through a user interface.

10. The method of claim 9 , further comprising determining, by the processor, that the future occurrence is atypical, and wherein determining of the guidance message is based at least in part on an atypicality of the future occurrence.

11. The method of claim 9 , wherein predicting the future occurrence of the host entering the second host state from the first host state comprises identifying a likely transition to the second host state, and wherein the second host state comprises an undesirable host state, and the guidance message is determined and delivered at a time such that the host can intervene to avoid the future occurrence of the host entering the second host state, wherein the time is during the pre-sleep or pre-exercise state.

12. The method of claim 9 , wherein the future occurrence of the host entering the second host state from the first host state is from a first disease state describing a first host disease stage to a second disease state indicating a second host disease stage, and wherein the processor is further configured to determine a second guidance message based at least in part on the second host disease stage.

13. A non-transitory computer-readable medium comprising instructions which, when executed by a processor, cause the processor to perform a method comprising:
receiving host glucose concentration measurements from a communication circuit in communication with a glucose concentration sensor;
predicting, using a machine learning model, a future occurrence of a host entering a second host state from a first host state, wherein the first host state is associated with a first glucose concentration profile and the second
