[Evaluation of FreeStyle Libre in pediatric t1dm: improved glycemic control, reduction in diabetic ketoacidosis and severe hypoglycemia]

Practicalities of Flash-monitoring systems utilization in the questionnaire survey of children and adolescents with type 1 diabetes mellitus

BACKGROUND: Children and adolescents with type 1 diabetes mellitus (T1DM) are recommended to perform self-control 6–10 times a day to maintain optimal blood glucose levels. Currently, there are various devices, such as glucometers, systems for continuous blood glucose monitoring and flash monitoring (FMS). In real clinical practice patients can combine the use of various devices and face with problems of their exploitation.

AIM: To investigate the peculiarities of FMS utilization by children and adolescents with T1DM using questionnaire survey.

MATERIALS AND METHODS: From 06.2020 till 05.2021, a survey of patients with T1DM was conducted as part of a single-center, observational, one-stage, uncontrolled study. The questionnaire contained questions regarding the number of measurements, circumstances and adverse reactions when using the devices.

RESULTS: We questioned 80 patients (47 girls and 33 boys) aged 11.7 (9.0; 14.0) years with DM1 for 4.9 (2.0; 7.0) years, HbA1c level 8.2 (6.8; 9.0)) which were in pediatric endocrinology department of the University Children’s Clinical Hospital.

The majority of patients (86.3%) scan the sensor more than 10 times a day; 25% of FMS-users measure blood glucose with glucometer not every day.

The majority of patients (51,3%) prefer to use FMS instead of glucometer in all circumstances. Patients face with errors using FMS more often than using glucometers — OR 3.4 (95% CI 1.7–6.8). Non-significant reaction to adhesive material disturbed 50.0% participants; one patient (1.3%) had to refuse FMS due to allergic reaction.

Among possible reasons to refuse FMS patients often name error, skin sealing, high price, inflammation, inconvenience to wear a device.

Additional measures for fixing FMS device are always used by 36,3% of patients, sometimes — 18,8%, in some situations (going in for sports, swimming, travelling, in case of unsticking at the end of term) — 15,0%.

CONCLUSION: Quarter of FMS users double-check glycaemia values rarer than recommended. Patients face with error using FMS more often than using glucometer. Local reaction to adhesive material does not influence FMS utilization. The majority of patients use additional measures for fixing FMS devices.
