Objectives: Type 2 diabetes is one of the leading chronic, non-communicable diseases of the world. Our aim was to determine the annual health insurance treatment cost of non-insulin-dependent diabetes with multiple complications in Hungary. Methods: Data were derived from the financial database of the NHIFA, for the year 2018. Data analysed included annual patient numbers, case numbers and prevalence of care utilisation per 100.000 population according to age groups and sex. The following health insurance treatment categories were included into our study: general practice care, home care, in-and outpatient care, medical imaging, laboratory diagnostics, drugs and medical aids. Patients with non-insulin-dependent diabetes with multiple complications were identified with the following code of the International Classification of Diseases 10 th revision: E1170. Results: The highest national patient numbers were in general practice care: 30,028 men, 32,355 women, in total 62,383 patients, followed by outpatient care (25,063 men, 26,021women, in total 51,084 patients), and use of pharmaceuticals (23,189 men, 24,126 women, in total 47,315 patients). Based on patient numbers in general practice care, prevalence in 100,000 among men was 642.8 patients, among women 633.6, in total 638.0 patients. Patients above age 55 accounted for 90.28%, those above age 65 accounted for 66.07% and patients aged above 75 accounted for 32.11% of patient numbers including all forms of care. Regarding sex, in general practice care 48.1% were men, 51.9% were women, the use of pharmaceuticals showed a similar ratio (49.0% were men and 51.0% were women). Conclusions: Regarding patients' sex, there was no difference between men and women at the onset of the disease. Age was found to have a significant impact upon prevalence of diabetes with multiple complications.
