How often do you do a blood test during the middle of the night on your child or yourself?

Poll dates: March 25 - April 1, 2009
Total Votes: 438

Research has shown that many people with diabetes have nighttime hypoglycemia and don't know it. Blood tests during the night can detect nighttime hypoglycemia or patterns of low blood sugars and help you take appropriate action to reduce the risk.

Since we first ran this poll in January 1999, we've seen a significant change in the number of people who report testing every night, with the number growing from 13% to 43%. Over half (52% of CGM users, 60% of non-CGM users) report checking at least once or twice a week. People who report testing only if low or ill, or testing rarely, both dropped too. These changes make it clear that more and more people are aware of the risk of nighttime hypoglycemia and are taking action -- by checking blood sugars -- to help prevent it.

Continuous sensing technology from Medtronic Diabetes, DexCom, and Abbott Diabetes Care have the potential to help enormously with nighttime monitoring by alarming only when blood sugars exceed pre-set boundaries. Parents who are now checking every night are definitely looking forward to reliable, accurate continuous sensing.

This poll separated CGM users from those using only blood glucose monitoring to try to get a sense for whether families were relying on CGM alarms at night. By separating the results and analyzing within group, we see that CGM users are still checking blood glucose levels at night -- in fact, exactly as often as those who don't use CGM (43%):

However, among CGM users, we do see many families reporting that they rely on either the sensor display (16%) or the sensor alarm (17%). We are hopeful that as CGM technology continues to improve and become more widespread, families of children with diabetes may be able to look forward to being able to sleep through the night more often while still ensuring that their children's blood glucose levels are being monitored.
