Hyperglycemic Alert Rate; Hyperglycemia Detection Rate - Dexcom G6 Pro User Manual

The High Glucose Alert
Estimates of how well the adjustable High Glucose Alert performs are
presented in Tables 5-C and 5-D. Tables 5-C and 5-D represent the
hyperglycemic alert evaluation within 15 minutes of the YSI value in
the study and the hypoglycemic event evaluation within 15 minutes of
each hyperglycemic alert for adults and pediatrics, respectively.

Hyperglycemic Alert Rate

The Alert Rate shows how often the alert is right or wrong. The True
Alert Rate is the % of time the device alarmed when the blood glucose
level was at or above the alert setting within 15 minutes before or after
the device alarmed. The False Alert Rate is the % of time the device
alarmed when the blood glucose level was below the alert setting
within 15 minutes before or after the device alarmed.
For example, if you set the High Glucose alert to 200 mg/dL and your
alarm sounds, how often can you expect your blood sugar to actually
be high? Based on results for adults in the G6 Study (Table 5-C), when
your alarm sounds, you can expect your blood sugar to be at or above
200 mg/dL approximately 96% of the time and not be above 200 mg/
dL approximately 4% of the time within the 15 minute period before or
after your alarm sounds.

Hyperglycemia Detection Rate

The Detection Rate is the % of time the device alarmed when the
blood glucose level was at or above the alert setting within 15 minutes
before or after the hyperglycemic event. The Missed Detection Rate is
the % of time the device did not alarm when the blood glucose level
was at or above the alert setting within 15 minutes before and after the
hyperglycemic event.
For example, if you set the High Glucose alert to 240 mg/dL and your
blood sugar rises above 240 mg/dL, how often can you expect your
device to correctly alarm you? Based on results for pediatrics in the
study (Table 5-D), if your blood sugar was at or above 240 mg/dL,
you can expect your alarm to sound approximately 90.2% of the time
within 15 minutes and an alarm not to sound approximately 9.8% of
the time.
