A Comparison of Peri-Operative and Post Acute Coronary Syndrome Glycaemic Control in Insulin Requiring Patients with Type 2 Diabetes at St Vincent’s Hospital With and Without Real-Time Continuous Glucose Monitoring.
Scientific title
In patients with type 2 diabetes treated with insulin, who are post-operative or post acute coronary syndrome, does real-time continuous glucose monitoring vs intermittant finger pricks improve glucose control.

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Real-Time Continuous glucose monitoring with Guardian Real-Time where glucose levels are displayed on the monitor every 5 minutes. If the levels are falling at >2mmol/20minutes or similarly rising at that rate, the monitor will alarm and thus appropriate interventions can be carried. Before any intervention is taken, the levels displayed are confirmed with a finger prick test. Subjects will be fitted with this monitor after surgery or the coronary event and will wear it up to 3 days post-event.
Intervention code [1] 2520 0
Treatment: Other
Comparator / control treatment
Intermittant glucose testing with finger pricks that will be carried out 4-6 times a day. The results obtained will require appropriate action as specified by the hospital's existing protocol for post-operative glucose control. Subjects here will also be fitted with the continuous glucose monitor but it will be blinded so as not to reveal the levels but rather to store it for retrospective comparison. Subjects will be monitored for a period up to 3 days from the event.

Active

Outcomes
Primary outcome [1] 3795 0
Time spent in the target glycaemic range, time spent in hypoglycaemic range and time spent in the hyperglycaemic range. These outcomes are measured from the data stored in the continuous glucose monitors and will be accessed via a corresponding computer programme.
Timepoint [1] 3795 0
1 to 3 days post event.
Secondary outcome [1] 6406 0
Glucose variablility as will be determined using Continuous Overlapping Net Glycaemia Action (CONGA).
Timepoint [1] 6406 0
1 to 3 days post event

Summary
Brief summary
In patients with type 2 diabetes, it is proven that good glucose control during stressful events like after surgery and after a heart attack helps improve the outcome. Therefore in patients with type 2 diabetes requiring insulin and undergoing stressful events, real-time continuous glucose monitoring which provides detailed information on the glucose trends may improve glucose control compared with intermittant glucose monitoring with finger pricks shich are "snap shots" of the ever fluctuating glucose level.
