Objective: To evaluate the baseline characteristics and their evolution three months after implantation of the Flash glucose monitoring System (Freestyle Libre), after financing by the Andalusian Health Service in patients under 18 years old with type 1 diabetes mellitus (DM1) in our hospital area.

Material and Methods: A descriptive observational and retrospective study that includes patients with DM1 under 18 years old from the southern hospital area of Granada who are implanted with the Flash System for glucose monitoring. Variables analyzed: sex, age, time of evolution of diabetes, previous HbA1c, period with glycemia ni range (70–180 mg/dl) and number of hypoglycaemias (<70 mg/dl) post-implantation of the system.

Results: Forty-two patients (54.8% were men), mean age 16.5 years. Median time of evolution of diabetes 5.95±4.71 years. 85.7% of patients were in treatment with bolus-basal therapy, 14.3% on ISCI therapy. Baseline HbA1c of 7.87±1.62%. All patients received a preimplantation education session of the device. After implantation, the average glucose was 177.18±41.9 mg/dl, with an estimated HbA1c of 7.61±1.3%. 59.5% of the patients presented glycemia within range (70–180 mg/dl) and 31% were above it. The number of hypoglycaemias register in that period was 11.78±12. Device usage: mean number of daily scans of 7.78±5.29 with an average of 77.04% of data captured by the reader. 9.5% of patients did not use the device, the main reasons were: disinterest on the part of the patient (7.1%) and one case due to problems with the device.

Conclusions: The preliminary results of the implantation of the flash system in a population younger than 18 years in our environment showed:

1. Tendency to improve metabolic control

2. An acceptable although improvable percentage of glycemias in rango

3. An optimal acceptance by the patients with an acceptable percentage of use.
