Introduction and Objective: Flash glucose monitoring is a form of interstitial glucose monitoring and it is indicated in patients with diabetes mellitus.The objetive of the study was to assess the effect of introducing flash glucose monitoring in adults with diabetes with respect to change in hemoglobin A1c (HbA1c).

Material and methods: Prospective observational study of adults with diabetes in our center, in whom a prescription for a flash glucose monitoring sensor was collected, started between June and November 2020. Primary outcome was change in HbA1c 12 months after initiation of flash glucose monitoring. Changes in fasting blood glucose 12 months after the start of monitoring were also studied.

Results: 77 subjects (55,8% men) were analysed with an average age of 47.3±13 years old with diagnosis of diabetes (71,4% DM1, 26% LADA, 2,6% DM2). The average of month with diagnosis of diabetes of our subjects were 169.8±10.3 months. Only 26% of subjets were well trained in the correct calculation of carbohydrate portions. We observed how the average HbA1c baseline 7.87±1.2%, and 12 after initiation of flash glucose monitoring was 7.33±1.2%, this results was statistically significant finding (P<0,001). Likewise, statistically significant changes in fasting blood glucose were found, baseline 168.9±74.8 mg/dl and 12 months after initiation of flash glucose monitoring 140.3±48.9 mg/dl. No changes were observed in either weight or insulin dose.

Conclusions: Flash monitoring is associated with significant reduction in HbA1c and fasting blood glucose in people with diabetes. Multiple causes can justify said improvement, and more studies are necessary to demonstrate the reason for these changes.
