Introduction: Adequate glycemic control is essential in the diabetes prognosis. It has been described that the use of glucose monitor systems leads to an improvement in different metabolic parameters as well as facilitating decision making.Material and methodsRetrospective observational study to evaluate the metabolic impact of flash sensor implantation in a cohort of patients with DM1 of Virgen de Valme University Hospital of Seville. All patients with implantation of the glucose monitoring system in the period 1/1/2020 to 3/31/2020 were included. Subsequently, different metabolic parameters were compared at baseline and at 3, 6 and 12 months after implantation. SPSS program was used for statistical analysis.

Results: 154 patients (46.7% men and 53.3% women) have been analyzed. Mean age 40.3±1.02 years. MDI treatment 87.3% vs CSII 12.7%. Previous HbA1c mean to the sensor was 8.03±1.35%, with a sustained reduction observed at 12 months (8.03±1.35% vs 7.68±1.01%; P = 0.036). Number of capillary controls before sensor was 3.57±0.23, with an increase in sensor scans at 12 months (3.57±0.23 vs 10.62±0.69; P = 0.000). Coefficient of variation before sensor was 47.15±2.08%, with a decrease observed at 12 months (47.15±2.08 vs 37.66±0.63%; P = 0.000). Hypoglycemia percentage before sensor was 13.83±1.26%, with a decrease observed at 12 months (13.83±1.26% vs 5.36±0.49%; P = 0.000). Percentage of time in range before sensor was 48.8±2.38, with an increase observed at 12 months (48.8±1.26 vs 59.58±1.48; P = 0.001). Percentage of hyperglycemia before sensor was 38.08±2.54, with a decrease observed at 12 months (38.08±2.54 vs 35.06±1.6; P = 0.043).

Conclusions: ‐ The implantation of the sensor has shown, as in the literature, improvement in metabolic control in terms of HbA1c, number of controls, coefficient of variation, hypo/hyperglycemia time and time in range. ‐ Some parameters showed initial improvement but attenuated over time.
