People with type 1 diabetes using real-time continuous glucose monitoring with alert functionality had better glycaemic control compared to individuals using intermittently scanned continuous glucose monitoring without alerts, latest evidence reveals.
A new study has discovered that hypoglycaemia worry is higher amongst people using real-time continuous glucose monitoring (rtCGM) with alert functionality than those using intermittently scanned continuous glucose monitoring (isCGM) without alerts.
Approximately 254 people with type 1 diabetes took part in the study. Each participant was placed into one of two groups: rtCGM with alerts group or the isCGM without alerts group.
The people in the isCGM without alerts group then joined the rtCGM with alerts group after six months.
Time in range (TIR) increased from 51.8 per cent at start of rtCGM (month six) to 63·5 per cent at month 12 in the is-rtCGM group and remained stable up to month 24, according to the results.
The authors said: “In the rt-rtCGM group, TIR increased from 52.5 per cent at start of rtCGM (month zero) to 63·0 per cent at month 12, also remaining stable up to month 24.
“HbA1c decreased from 7·4 per cent (57 mmol/mol; month 6) to 6·9 per cent (52 mmol/mol) at month 24 in the is-rtCGM group, and from 7·4 per cent (57 mmol/mol; month 0) to 7·0 per cent (53 mmol/mol) at month 24 in the rt-rtCGM group.”
They conclude: “The change in hypoglycaemia worry score was 2·67 in the is-rtCGM group and 5·17 points in the rt-rtCGM group.
“Time in clinically significant hypoglycaemia was unchanged in both groups after month 12. Severe hypoglycaemia decreased from 31 to 3·3 per 100 patient-years after switching to rtCGM.”
