Background and Aims
We have previously shown beneficial effectsof FSL monitoring on glycaemic control and hypoglycaemia awareness in people living with diabetes. In this study we investigate the long term (≥ 2 years) effect of FSL on glycaemic control and hypoglycaemia awareness.

Methods
Clinicians from 106 NHS hospitals in the U.K. submitted FSL user data, collected during routine clinical care, to a secure web‐based tool held within the NHS N3 network. The student t‐test was used to compare the baseline and follow‐up HbA1c, GOLD score (measure of hypoglycaemia awareness) and other baseline demographic characteristics.

Results
A total of240 FSL users with ≥2 years follow‐up were identified, mean age of 36.2 ± 19.8 years, 50% females, diabetes duration 20.1 ± 16.4 years, BMI of 24.5 ± 5.7 kg/m2 and mean follow‐up 2.85 ± 0.79 years. These participants showed a ‐4.6 mmol/mol change in HbA1c, reducing from 62.4 ± 14.8 mmol/mol to 57.8 ± 11.9mmol/mol at follow‐up (P = 0.0002). The HbA1c reduction was greater in those with a high baseline HbA1c (≥69.5 mmol/mol) reducing from 81.5 ± 13.0mmol/mol to 66.5 ± 14.4 mmol/mol (P < 0.0001). The baseline GOLD score was 2.8 ± 1.7, which improved to 2.1 ± 1.2 (P < 0.0001) at follow‐up.

Conclusions
People living with diabetes who used the FSL for >2years demonstrated benefits in both glycaemic control and hypoglycaemia awareness.
