Clinical protocol of a new study to evaluate the impact of telemonitoring in the management of diabetes. The study TELESAGE has been conducted in a larger population of diabetic patients based in France (100 centers) with poorly controlled basal-bolus insulin levels. The telemonitoring tool used is Diabeoยฎ a class IIb CE-marked medical device that provides therapeutic support to aid basal and bolus insulin titration.
