Abstract

Methods and system to provide glycemic control and therapy management based on monitored glucose data, and current and/or target Hb1AC levels are provided.

Claims

1. A method, comprising:

receiving mean glucose value information of a patient based on a predetermined time period;

receiving an HbA1C level of the patient;

determining a correlation between the received mean glucose value information and the HbA1C level; and

determining a target HbA1C level based on the determined correlation.

2. The method of claim 1 wherein receiving mean glucose value information includes:

receiving monitored glucose level information over the predetermined time period; and

applying a weighting function to the received monitored glucose level information.

3. The method of claim 2 wherein the weighting function is based on a time of day information associated with the received monitored glucose level information.

4. The method of claim 2 wherein the weighting function is based on a time period associated with the received monitored glucose level information.

5. The method of claim 1 wherein determining the target HbA1C level includes:

receiving one or more patient specific parameters; and

applying the received one or more patient specific parameters to the determined correlation between the received mean glucose value information and the received HbA1C level.

6. The method of claim 5 wherein the one or more patient specific parameters includes an age of the patient, a history of hypoglycemia, an activity level of the patient, a medication intake information of the patient, or a risk associated with high or low blood glucose levels of the patient.

7. The method of claim 1 wherein the determined correlation between the received mean glucose value information and the received HbA1C level includes a rate of glycation of the patient.

8. The method of claim 1 wherein the predetermined time period includes one of approximately 30 days, approximately 45 days, or approximately 90 days.

9. The method of claim 1 including outputting the determined target HbA1C level.

10. The method of claim 1 including storing one or more of the mean glucose value information, the received HbA1C level, the determined correlation between the received mean glucose value information and the HbA1C level, and the determined target HbA1C level.

11. An apparatus, comprising:

a communication interface;

one or more processors operatively coupled to the communication interface; and

a memory for storing instructions which, when executed by the one or more processors, causes the one or more processors to receive mean glucose value information of a patient based on a predetermined time period, receive a HbA1C level of the patient, determine a correlation between the received mean glucose value information and the HbA1C level, and to determine a target HbA1C level based on the determined correlation.

12. The apparatus of claim 11 wherein the memory for storing instructions which, when executed by the one or more processors, causes the one or more processors to receive monitored glucose level information over the predetermined time period, and to apply a weighting function to the received monitored glucose level information.

13. The apparatus of claim 12 wherein the weighting function is based on a time of day information associated with the received monitored glucose level information.

14. The apparatus of claim 12 wherein the weighting function is based on a time period associated with the received monitored glucose level information.

15. The apparatus of claim 11 wherein the memory for storing instructions which, when executed by the one or more processors, causes the one or more processors to receive one or more patient specific parameters, and to apply the received one or more patient specific parameters to the determined correlation between the received mean glucose value information and the received HbA1C level.

16. The apparatus of claim 15 wherein the one or more patient specific parameters includes an age of the patient, a history of hypoglycemia, an activity level of the patient, a medication intake information of the patient, or a risk associated with high or low blood glucose levels of the patient.

17. The apparatus of claim 11 wherein the determined correlation between the received mean glucose value information and the received HbA1C level includes a rate of glycation of the patient.

18. The apparatus of claim 11 wherein the predetermined time period includes one of approximately 30 days, approximately 45 days, or approximately 90 days.

19. The apparatus of claim 11 including an output unit operatively coupled to the one or more processors for outputting the determined target HbA1C level.

20. The apparatus of claim 11 wherein the memory for storing instructions which, when executed by the one or more processors, causes the one or more processors to store one or more of the mean glucose value information, the received HbA1C level, the determined correlation between the received mean glucose value information and the HbA1C level, and the determined target HbA1C level.
