Measure
Sensor Based Glucose Monitoring System
Standard system use for 6 months. Followed by open access to the device for 6 months. Sensor Based Glucose Monitoring System: Subjects will wear the Abbott Sensor Based Glucose Monitoring System (unmasked) for 6 months to monitor their glucose levels. Post completion of the 6 month intervention, subjects participating in this arm of the study will be given a further 6 month period of open access to the device. All subjects will wear a masked Abbott Sensor Based Glucose Monitoring System, for 14 days prior to randomisation.
Standard Blood Glucose Monitoring
Subjects randomised to the control group will be given blood glucose meters for monitoring for the 6 months study duration. Standard Blood Glucose Monitoring: Subjects will use an Abbott Blood Glucose Monitoring System (standard blood glucose meter) for 6 months to monitor their glucose levels. A 14-day masked wear of the Abbott Sensor Based Glucose Monitoring System is included for these subjects at the 6 month time point, to collect glycaemic variability data for comparison to the intervention group of the study. All subjects will wear a masked Abbott Sensor Based Glucose Monitoring System, for 14 days prior to randomisation.

SECONDARY outcome

Timeframe: Baseline and 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).

Measure
Sensor Based Glucose Monitoring System
n=149 participants at risk
Standard system use for 6 months. Followed by open access to the device for 6 months. Sensor Based Glucose Monitoring System: Subjects will wear the Abbott Sensor Based Glucose Monitoring System (unmasked) for 6 months to monitor their glucose levels. Post completion of the 6 month intervention, subjects participating in this arm of the study will be given a further 6 month period of open access to the device. All subjects will wear a masked Abbott Sensor Based Glucose Monitoring System, for 14 days prior to randomisation.
Standard Blood Glucose Monitoring
n=75 participants at risk
Subjects randomised to the control group will be given blood glucose meters for monitoring for the 6 months study duration. Standard Blood Glucose Monitoring: Subjects will use an Abbott Blood Glucose Monitoring System (standard blood glucose meter) for 6 months to monitor their glucose levels. A 14-day masked wear of the Abbott Sensor Based Glucose Monitoring System is included for these subjects at the 6 month time point, to collect glycaemic variability data for comparison to the intervention group of the study. All subjects will wear a masked Abbott Sensor Based Glucose Monitoring System, for 14 days prior to randomisation.
