Continuous Sensing, Other

Question from Georgia, USA:

My question is twofold. We moved from a larger city to a smaller city. There is only one pediatric endocrinologist in town. It was my understanding (inaccurate information!) when we moved here, that there were five from which we could choose; this is not the case. This one endocrinologist in town did not look at my child’s blood sugar log, did not examine her, did not offer any instruction to assist us, could not tell us of any advances being made in technology or anything, did not inquire into the insulin regimen my daughter is on. Even all the NON endocrine doctors we have seen want to know this. We have NEVER experienced anything like this in any doctor we have ever seen before. He could be overwhelmed being the only one in town. First Do you know of any great pediatric endocrinologists in the Atlanta. Georgia area? Sorry to sound like I’m complaining, but we have always had such good doctors before moving here. Second Do you know of any information or studies regarding accuracy and superiority in one Continuous Glucose Monitor over another?

It sounds like the wrong doctor. I would recommend Dr. Robert Schultz or Dr. Steve Anderson, both with a large pediatric diabetes practice in Atlanta. They have a full team including nurses, dietitians, social workers, etc. Another group is with Dr. Inger Hansen at Emory. All three are excellent and should provide the type of care and follow-up that you are asking for and that is more appropriate. Please feel free to use my name as a referral source.

With respect to your second question, at this time, the DexCom and the Medtronic Guardian are the two most commonly available CGMS. Abbott’s Navigator is rarely available in the U.S. The DexCom is a bit more accurate and easier to use but does not yet have a system with the pumps so one must use two separate receivers. Medtronic’s system works in a unified fashion with their own pumps. DexCom is a bit more accurate in the hypoglycemia range than the Guardian and also lasts several days longer than the Medtronic system. Both are getting better with newer developments the past few years. Most large diabetes practices utilize both systems and discuss with patients which would be more preferable for them.


[Editor’s comment: There are no recent studies comparing the available CGM devices.
