Introduction: Funding of continuous glucose monitoring (CGM) has been established by Madrid Health Service for adults with type1 Diabetes Mellitus (DM) who meet specific criteria. This has brought to lightthe need foran increasedinvestment in care time. In our Division, a structured training program has been established, consisting of 2 training sessions (TS); the first one based on basic contents to initiateFlash-CGM, and the second one, more intensive and targeted, focused on the correct interpretation of the resulting data.

Aims: To evaluateglucose control of patients with type 1DM after undergoing a structured training program on theuse of Flash-CGM and toevaluatethe degree of patient satisfaction withtrainingitself, and regarding their management of DM.

Methods: Analysis of downloaded LibreView data of 50 patients using Flash-CGM. Description of demographic and analytical variables, and those related to glycaemic control provided by Flash-CGM system, after undergoing two TS separated in time. Descriptive and inferential statistics: SPSSv.25

Results: 50 patients with type1 DM, 27 women, aged 39 [18–86], mean DM duration 20.76 ± 12.27 years. Initial/previous/prior Hba1c: 7.3% [5.5–9.3%]. 5 used insulin pump and 21 were previous users of Flash-CGM. Number of scans/day:17 in pump-patients, 12 in patients on multiple daily injections. A decrease in mean HbA1c was noted with use of Flash-CGM (7.224 to 7.092%, P = 0.117). No significant differences in glycaemic control adjusted for DM duration, gender, BMI, time using Flash-CGM or being on a pump were found between the two TS. We observeda decrease in the number of scans in non-previous users after the second TS (12.25 ± 4.84 to 11.11 ± 4.37, P = 0.021). Younger users (≤ 39 years) reduced their number of scans after the second TS (13.16 ± 5.71 to 11.04 ± 4.12 (P = 0.001). No significant correlation between the number of scans and time in range was found after the first TS. There was a significant correlation between the number of scans and time in range after the second TS (beta regression coefficient 0.371, P = 0.009). Hypoglycaemic events and time in hypoglycaemia improved (15.75 ± 16.30 (1st TS) to 13.57 ± 6.8 (2nd TS) and 106.78 ± 34.5 min (1st TS) to 104.59 ± 37.98 min (2nd TS), (non-significant decrease). Patients showed a high degree of satisfaction (93% in DTSQ-c scale), better understanding of DM (95.4% DTSQ-c) and of glycaemic behaviour (93.3% EVA scale), and an overall high satisfaction (88.8%) with the training program received.

Conclusion: Flash-CGM increases time in range, HbA1c and quality of life. After the training program, satisfaction and understanding of glycaemic behaviour improve, denoting the importance of a continuous training process.
