Arms of the Study

Arm 1

Arm 2

Arm Type

Experimental

Active Comparator

Arm Label

Sensor Based Glucose Monitoring System

Standard Blood Glucose Monitoring

Arm Description

Standard system use for 6 months. Followed by open access to the device for 6 months.

Subjects randomised to the control group will be given blood glucose meters for monitoring for the 6 months study duration.

Outcomes

Primary Outcome Measures

HbA1c at 6 Months
Difference in HbA1c between intervention and control group at day 194 adjusting for baseline HbA1c at day 1 using ANCOVA.

Secondary Outcome Measures

Time in Range
Difference in time in range 70-180 mg/dL between intervention and control group assessed in days 194 to 208 adjusting for baseline (days 1 to 15 time in range) using ANCOVA.
Time Spent <70 mg/dL and <55 mg/dL
Difference in time <70 mg/dL and <55 mg/dL (hours per day) between intervention and control group assessed in days 194 to 208 adjusting for baseline (days 1 to 15) using ANCOVA.
Frequency of Episodes <70 mg/dL and <55 mg/dL
Difference in frequency of episodes <70 mg/dL and <55 mg/dL (number per day) between intervention and control group assessed in days 194 to 208 adjusting for baseline (days 1 to 15) using ANCOVA.
Time Spent >180 mg/dL and >240 mg/dL
Difference in time >180 mg/dL and >240mg/dL (hours per day) between intervention and control group assessed in days 194 to 208 adjusting for baseline (days 1 to 15) using ANCOVA.
Number of Glucose Measurements Performed
Number of blood glucose fingerstick tests per day by intervention and control group during days 15 to 208. The number of sensor scans performed by the intervention group during days 15 to 208.
System Utilisation
Sensor utilisation assessed by percentage of sensor glucose data collected by the intervention group.
Change in Diabetes Treatment Satisfaction Questionnaire (DTSQc) Scores From Day 1 to Day 194.
The Diabetes Treatment Satisfaction Questionnaire change (DTSQc) score is used to assess relative change in participant satisfaction from baseline. The questionnaire consists of 8 items, 6 of which (1 and 4 through 8) assess treatment satisfaction. Each item is rated on a 7-point Likert scale (which ranges from -3 (much less satisfied) to +3 (much more satisfied). The scores from the 6 treatment satisfaction items are summed to a Total Treatment Satisfaction Score, which ranges from -18 (much less satisfied) to +18 (much more satisfied). There is one question to assess the change in perceived frequency of Hypoglycaemia and one question to assess change in perceived frequency of Hyperglycaemia. Each question is rated on a 7-point Likert scale (-3 to +3), -3 (much less of the time now) to +3 (much more of the time now). The ANCOVA adjusts for baseline DTSQs (status version).
