Introduction:According to the latest epidemiological data, around 537 million people worldwide (approximately 61 million in Europe) suffer from diabetes. The number of people suffering from this disease has increased significantly in recent decades. This especially applies to type 2 diabetes, which affects as many as 90% of people with diabetes. According to the results of epidemiological studies, in about 36% of people, diabetes is not detected and therefore is not treated adequately. The above is worrying, as is the information about a large number of people with the disease who fail to achieve good glycemic control, which otherwise could and should be the key to improving their quality of life and reducing the risk of developing complications of this disease. Aim: To examine the impact of structured education on glycemic regulation in people with type 2 diabetes. Materials and methods: A retrospective study was conducted by searching the electronic medical records of the Zadar General Hospital. Electronic documentation and specific key parameters for the assessment of disease control of people with type 2 diabetes treated and educated in the Daily Hospital for Diabetes and then examined at a control examination in the Outpatient Clinic for Endocrinology, Diabetes and Metabolic Diseases were searched and analyzed. Results: In all analyzed groups, regardless of gender and age, a significant decrease in HbA1c values and a reduction in body weight and BMI were recorded between the two measurements. Older groups and those younger than 50 years have somewhat weaker statistical significance regarding the mentioned changes, which can be shown by a smaller change or greater variability within these groups. The results are positive because they indicate a general improvement of the tested health parameters across all groups of respondents. Conclusion: Structured education affects better regulation of glycemia, hence "better values" have been achieved in the second act of measurement, following the education, confirming its contribution to better control of diabetes and consequently reduction of acute and/or chronic complications, as well as the development of other comorbidities that can occur due to poor glucoregulation.
