Develop Novel Methods to Display, Report and Analyze CGM Data for Clinical Decision-Making in People With Diabetes

There are two purposes to the study. First, to use an investigational device, the FreeStyle Navigator Continuous Glucose Monitoring (CGM) System (Abbott Diabetes Care) to obtain sufficient longitudinal data in order to develop a method for reporting CGM data in a manner that provides clinical information that is not available using conventional SMBG. The long-term goad is to determine the manner and degree to which CGM contributes to clinical decision-making. Because of the evidence that glucose regulation may be indirectly related to blood pressure levels, a second purpose of the study is to monitor variation in BP control by means of self-monitored BP.
