Summary

• Intelligent devices are being evaluated and
  designed to improve BG control in diabetes with
  less effort.
• Intelligent devices solve a critical problem
  that the current treatment interval of 3 to 4
  months between doctors visits is too long
• Intelligent devices can deliver useful control
  advice at any time of day
• Devices provide short treatment intervals and
  thereby shorten the time to goal
