Primary Outcome Measures:
  • the percentage of glucose values obtained every 15 min in predefined glucose ranges [ Time Frame: 15 minutes ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Injected insulin dose [ Time Frame: 24 hours ] [ Designated as safety issue: Yes ]
  • Accuracy of the glucose monitoring unit [ Time Frame: 24 hours ] [ Designated as safety issue: No ]
    The absolute and relative difference between glucose monitoring readings and reference values (blood glucose) will be used to determine the accuracy of the monitoring unit

Estimated Enrollment: 20
Study Start Date: January 2013
Estimated Study Completion Date: April 2014
Estimated Primary Completion Date: March 2014 (Final data collection date for primary outcome measure)
