Abstract

Method and system for providing diabetes management and insulin therapy based on substantially real time glucose monitoring system is provided.

Claims

1. A method, comprising:

determining, using one or more processors, a rate of change of a monitored glucose level for a predetermined time period;

extrapolating, using the one or more processors, a projected glucose level based on the determined rate of change of the monitored glucose level;

determining, using the one or more processors, after insulin therapy initiation, whether the insulin therapy is having an intended therapeutic result;

generating, using the one or more processors, a modification to a therapy profile associated with the insulin therapy based on data associated with the monitored glucose level; and

updating, using the one or more processors, an insulin sensitivity factor on an ongoing basis based at least in part on a comparison of the projected glucose level with the monitored glucose level.

2. The method of claim 1, further including displaying the generated modification to the therapy profile.

3. The method of claim 2, wherein the generated modification to the therapy profile is displayed as one or more of an alphanumeric output display, a graphical output display, an icon display, a video output display, a color display or an illumination display.

4. The method of claim 1, wherein the therapy profile includes one or more of a basal profile, a correction bolus, a temporary basal profile, an insulin sensitivity, an insulin on board level, or an insulin absorption rate.

5. The method of claim 1, wherein generating the modification to the therapy profile associated with the monitored glucose level includes retrieving a current glucose rate of change information.

6. The method of claim 5, wherein generating the modification to the therapy profile includes determining a modified glucose rate of change information based on the data associated with the monitored glucose level.

7. The method of claim 6, further including generating an output alert based on the modified glucose rate of change information.

8. The method of claim 6, further including determining a glucose level projection information based on the modified glucose rate of change information.

9. A system, comprising:

an interface unit;

one or more processors coupled to the interface unit; and

a memory for storing instructions which, when executed by the one or more processors, causes the one or more processors to determine a rate of change of a monitored glucose level for a predetermined time period, to extrapolate a projected glucose level based on the determined rate of change of the monitored glucose level, to determine after insulin therapy initiation whether the insulin therapy is having an intended therapeutic result, to generate a modification to a therapy profile associated with the insulin therapy based on data associated with the monitored glucose level, and to update an insulin sensitivity factor on an ongoing basis based at least in part on a comparison of the projected glucose level with the monitored glucose level.

10. The system of claim 9, wherein the interface unit includes an input unit and an output unit, the input unit configured to receive the data associated with the monitored glucose level, and the output unit configured to output the generated modification to the therapy profile.

11. The system of claim 9, wherein the interface unit and the one or more processors are operatively coupled to one or more of a housing of an infusion device or a housing of an analyte monitoring system.

12. The system of claim 9, wherein the memory is further configured for storing instructions which, when executed by the one or more processors, causes the one or more processors to display the generated modification to the therapy profile.

13. The system of claim 12, wherein when the memory is configured for storing instructions which, when executed by the one or more processors, causes the one or more processors to display the generated modification to the therapy profile as one or more of an alphanumeric output display, a graphical output display, an icon display, a video output display, a color display or an illumination display.

14. The system of claim 9, wherein the therapy profile includes one or more of a basal profile, a correction bolus, a temporary basal profile, an insulin sensitivity, an insulin on board level, or an insulin absorption rate.

15. The system of claim 9, wherein the memory is further configured for storing instructions which, when executed by the one or more processors, causes the one or more processors to retrieve a current glucose rate of change information.

16. The system of claim 15, wherein the memory is further configured for storing instructions which, when executed by the one or more processors, causes the one or more processors to determine a modified glucose rate of change information based on the data associated with the monitored glucose level.

17. The system of claim 16, wherein the memory is further configured for storing instructions which, when executed by the one or more processors, causes the one or more processors to generate an output alert based on the modified glucose rate of change information.

18. The system of claim 16, wherein the memory is further configured for storing instructions which, when executed by the one or more processors, causes the one or more processors to determine a glucose level projection information based on the modified glucose rate of change information.
