Appliance of continuous glucose monitoring system as an educational tool in patients with type 2 diabetes

Type 2 diabetes mellitus is an economical, medical and social problem. Patients with type 2 diabetes live shorter compared to peers without diabetes, mainly because of cardiovascular diseases. The basis of the treatment of these illness is multifactor therapy focused on cardiovascular risk factors, including hyperglycemia. Continuous glucose monitoring is a small device, which measures glucose level in tissue fluid every few minutes. It allows to observe glucose trends on the graph. One of the most popular system is Free Style Libre, it is based on scanning. Patient should fix sensor every 2 week on the back of the arm. To check glycemia, patient should bring the reader closer to sensor. The reader is a mobile phone or special device from producer, which is equipped with NFC. The measurement is non-invasive, without repeated finger pricks. Recent years have provided convincing evidence that the continuous, long-term use of registered continuous monitoring systems (CGMS) can be treated as a therapeutic method in patients with type 1 diabetes and type 2 diabetes treated intensively with insulin. Compared to people using glucometers, patients using CGM systems, including FreeStyle Libre, achieve better diabetes control, have fewer hypoglycaemic episodes, and their quality of life improves. Much less data concerns patients with type 2 diabetes remaining on less intensive therapeutic models, for example oral drugs or GLP-1 receptor analogues. Several publications from recent years show that they can also benefit from better metabolic control. The hypothesis that the temporary, educational use of the CGM system may have clinical significance in patients at the early stage of type 2 diabetes requires verification. The aim of the study is to evaluate the effectiveness of an educational intervention involving the periodic use of the Freestyle Libre 2 CGM system in patients at an early stage of type 2 diabetes.
