Introduction: Flash glucose monitoring expansion to an increasing number of patients with type 1 diabetes, coupled with its increased accuracy and ease of use, has increased available data on glycemic control in this population and allows detection of improvement areas in diabetes education and treatment.

Objective: To analyze main parameters standardized by ATTD consensus (2019) in our population of patients with type 1 diabetes using flash glucose monitoring.

Material and methods: Cross-sectional study carried out on May 7, 2021. Glucose profile of patients with medical follow-up in Endocrinology service in Virgen de la Victoria Hospital in Malaga were analyzed on Libreview platform. Those patients without download available in previous two weeks were excluded.

Results: 1,562 patients were analyzed. 51.2% were male. Average number of readings was 10.98±8.13 daily readings with 84.11±20.74% active time. Mean glucose was 165.34±39.04 mg/dl with a standard deviation (SD) 61.81±18.80 mg/dl and a coefficient of variation 37.31±7.52%. time in range (TIR) was 58.96±18.86%, time above range (TAR) was 35.66±19.92%, and time below range (TBR) was 5.38±6.25%. 28.83% patients achieved an TIR greater than 70%, 63.5% a TBR less than 5% and 33.74% a TAR less than 25%. Average interquartile range was 88.09±31.14. Mean hypoglycemia number is 0.65±0.54 daily events, with a mean duration of 90.53±54.51 minutes.

Conclusions: Glycemic control in our cohort of patients, although similar to populations with same characteristics, is still far from parameters recommended in ATTD consensus. We must exploit flash glucose monitoring to detect possible areas for improvement both individual and populationally.
