NCT00467688

Brief Summary

The objective of this cross over study is to access if continuous glucose monitoring (CGMS) with a real time feed back and hypoglycemic as well as hyperglycemic glucose alerts vs. only retrospective analysis of glucose values is able to improve course of glucose with special regard to time spent in hypoglycemic glucose ranges in type 1 diabetic patients with impaired hypoglycemia awareness or a history of severe hypoglycemia. The second objective is to access satisfaction with CGMS during both conditions

Outcome Measures

Primary Outcomes (1)

  • Daily time spent in the hypoglycemic glucose range during continuous glucose measurement with and without real time access to glucose values and glucose alarms

    during the 48 hours of using blind vs. unblind continuous glucose monitoring

Secondary Outcomes (1)

  • Time spent in euglycemic and hyperglycemic glucose range Satisfaction with CGMS Diabetes related distress Treatment satisfaction Anxiety and depressive symptoms

    During and after the 48 hours measurement of CGMS

Study Arms (2)

A,1

NO INTERVENTION

Real time access to current measured glucose values; hyperglycemic or hypoglycemic alerts

Device: Real time access to current glucose values during CGMS

A,2

NO INTERVENTION

Retrospective analysis of glucose values

Device: Real time access to current glucose values during CGMS

Interventions

One arm gets real time access to current measured glucose values and hypoglycemic or hyperglycemic alerts are elicited, The second arm get´s a retrospective analysis of glucose values
