Abstract

Background and Aims

Since the development of Continuous Glucose Monitoring, new metrics have emerged for assessing glycemic control. During ATTD 2019 congress, targets for glycemic control were set : time in range > 70% and time in hypoglycemia < 4% for most of diabetic patients. The aim of this study was to assess the percentage of diabetic patients achieving these objectives in our center.

Methods

All patients who received Freestyle Libre (FSL) training between June 2017 and May 2018 were included, except pregnant women. The training included an education session with a nurse and a diabetologist. Patients received a written educational document. Data from the FSL downloading three months after training were analyzed. The primary endpoint was the percentage of patients achieving the objectives set at ATTD.

Results

581 patients were trained. 99 patients were excluded (incomplete FSL download, pregnancy). Data were analyzed for 482 patients (251 women), treated with multiple daily injections (n=222) or with pump (n=260). 81,5% had type 1 diabetes. Only 4,1% of patients with a HbA1c target <7% achieved the objectives set at ATTD, and 4,9% of patients with a HbA1c target between 7 and 8%. HbA1c decreased from 63 mmol/mol (7.87%) before FSL training to 59 mmol/mol (7.57%) three months later (p < 0.001).

Conclusions

In spite of the improvement in HbA1c after FSL initiation, very few of our patients achieved the targets set at ATTD. According to these results, one can wonder which means could be put in place to have more patients reaching these objectives.
