Assessing Measures of Glycemic Variability

Abstract

Methods, devices and systems for receiving an instruction to determine a glycemic variation level, retrieving a stored metric for determining the glycemic variation level, retrieving one or more parameters associated with the retrieved metric analysis, determining the glycemic variation level based on the retrieved one or more parameters for the retrieved metric analysis, and outputting the determined glycemic variation level when it is determined that the retrieved one or more parameters associated with the retrieved metric analysis meets a predetermined condition are disclosed.

1 . (canceled) 
     
     
         2 . A computer-implemented method comprising:
 generating glucose sensor data indicative of a host's glucose concentration using a glucose sensor;   calculating a glycemic variability index value based on the glucose sensor data; and   providing output to a user responsive to the calculated glycemic variability index value.   
     
     
         3 . The method of  claim 2 , wherein the providing output comprises generating a report to a user, wherein the report includes a calculated GVI numerical value. 
     
     
         4 . The method of  claim 2 , wherein the providing output comprises triggering an alert to a user when the GVI exceeds a predetermined threshold, wherein the alert is one or more of an audible alert, visual alert and tactile alert. 
     
     
         5 . The method of  claim 2 , wherein the calculating is automatically performed periodically on a defined window of time of sensor data. 
     
     
         6 . The method of  claim 2 , wherein the calculating comprising calculating a plurality of GVI values based on the sensor data, wherein each of the GVI values is based on a different period of time of the sensor data. 
     
     
         7 . The method of  claim 2 , wherein the method is performed by a processor executing code embodied in a non-transitory computer-readable medium.
