Flash glucose monitoring (FGM) is widely used to evaluate glycemic control in people living with type 1 diabetes mellitus (PLWT1DM). Analysis of the ambulatory glucose profile (AGP) can improve individualized diabetes care and self-care in PLWT1DM. In real life, FGM improves glycemic control and quality of life, and reduces the burden of hypoglycemia [1,2]. However, knowledge of glucometrics in PLWT1DM using FGM may not be adequate, and areas for improvement can be identified and implemented.

We performed a cross-sectional study in the routine clinical practice setting, with sequential sampling of PLWT1DM (Freestyle 2, time of FGM ≥ 70%) in nine outpatient endocrinology clinics in Spain. Knowledge was assessed by a 17-question self-administered online survey, developed by the research team, that include definitions of glucometrics, actions taken according to trend arrows, and items related to data analysis by PLWT1DM. The survey produced a “global score” ranging from 1 to 16 (one

Three hundred six PLWT1DM responded to the questionnaire (45% women, age 48 [range 38-59] years). Their body mass index was 25.2 [22-5-28.3] kg/m2. Retinopathy was present in 31%, diabetic kidney disease in 9%, and neuropathy in 13%. The treatment modality was continuous subcutaneous insulin infusion in 5%. Only 68% of respondents reported to have received specific training in FGM.

Duration of diabetes was 22 [12-31] years, time since initiation of FGM was 32 [22-36] months. Median sensor active

The relationship between health/diabetes literacy and glycemic control is controversial [3]. To our knowledge, this is the first study using this approach. Only one study [4] has examined the impact of diabetes knowledge on metabolic control in PLWT1DM initiating FGM, focusing on assessing diabetes literacy in PLWT1DM, without including glucometrics targets or real-time and retrospective interpretation of the information provided by the FGM. An association between diabetes knowledge and

In conclusion, in PLWT1DM managed in endocrinology units, there is room for improvement in both glucometrics knowledge and the analysis and use of FGM data. Strategies aimed at improving knowledge and retrospective data analysis are necessary. They may lead to better glycemic control and greater efficiency of this technological tool for self-management of the disease.
