Continuous glucose monitoring is an evolving technology that is gradually replacing fingerprick glucose measurements in the management of type 1 and insulin-requiring type 2 diabetes. It provides a complete picture of a patient’s glycaemic pattern, leading to improved diabetes control.
- Unlike self-monitoring of blood glucose (SMBG), continuous glucose monitoring (CGM) provides patients with the opportunity to monitor glucose levels continuously, and to review the trend and rate of glucose changes, which predict impending hypoglycaemia and hyperglycaemia.
- Numerous studies have shown the clinical benefits of improved glycaemic control in patients with type 1 and insulin-requiring type 2 diabetes using CGM compared with SMBG.
- The main barrier to the use of CGM is cost.
- CGM data reporting has been standardised, providing clinicians with a guide for structured interpretation.
- The ‘artificial pancreas’ comprises a CGM system integrated into an automated insulin delivery device.
