Objective: Flash glucose monitoring (FGM) allows non-invasive glucose level assessment. Our objective was to describe the characteristics of patients in a secondary referral hospital and their glycemic control expressed as FGM targets.Methods and patientsObservational longitudinal clinical study between January 2021 and December 2021 in patients with DM1 referred to a secondary care center in Montilla (Córdoba).

Results: 101 patients included. Mean age: 42.38 ± 15.63 years, with a mean DM evolution time of 19.46 ± 12.49 years. 44.6% women. Mean HbA1c 7.75 ± 1.13%. FGM metrics: 56.57 ± 18.58% time in range, 23.5 ± 10.74% time between 180-250 mg/dl, 15.87 ± 17.05% time above 250 mg/dl, 3.90 ± 4.50% time between 54-70 mg/dl, 0.84 ± 1.90% time below 54 mg/dl. Glycemic CV 37.31 ± 7.32%. Among users of FGM, those categorized as well-controlled patients have to fulfill the following criteria: TIR≥70%, TAR ≤25%, TBR≤4% with a CV ≤ 36% as long as ≥70% of glucose data is obtained. In 64.4% of our patients ≥70% of glucose data was registered with FGM. In this subgroup 10.8% of patients fulfilled well-controlled criteria. The reason why patients did not achieve the criteria of adequate control is shown in table 1.

Conclusion: ‐ In our series of patients, more than a third of them (35.6%) don’t present with enough FGM data. ‐ensp;Out of patients with enough FGM data, only 10.8% patients of them achieve a good control if we use FGM criteria for adequate glycemic control. ‐ Among the criteria of good glycemic control, TIR is the least achieved in our patients (21.5%), whereas adequate TBR was the most achieved criterium (63.1%).
