Prevalence of diabetes in Poland in the years 2010–2014

Abstract

Introduction. Each year diabetes affects larger and larger number of people. Despite this fact, the number of people suffering from diabetes in Poland is not known precisely. In order to assess this prevalence, the thesis aims at assessing the prevalence of diabetes in the years 2010–2014 in the total Polish population by using the databases of the National Health Fund.

Material and methods. In the period from 1st January 2010 until 31st December 2014 patients were distinguished according to PESEL (Personal Identification) numbers: 1. for whom health care providers have indicated diabetes-related ICD-10 codes as the main cause of the medical intervention in billing reports; 2. who had got their prescriptions filled for any hypoglycemic agents or for glucose meter test strips. The number of patients recorded as diabetes patients according to the ICD-10 code and the number of patients who had their prescriptions filled for hypoglycemic agents or test strips were assessed. On the basis of these data the prevalence of diabetes (percentage of people with diabetes in a given year or a percentage of people who had got their prescriptions filled for hypoglycemic agents or test strips in relation to the general population) in respective years and an average prevalence rate for respective voivodeships were assessed.

Results. The average percentage of people with diabetes in the years 2010–2014 were found to be 4.47% (± 0.09%). This percentage has gradually increased in the consecutive years from 4.39% in 2010 to 4.61% in 2014. The average percentage of people who had got their prescriptions filled for diabetes related medicines or glucose meter test strips amounted to 5.88% in the years 2010–2014. The largest percentage of people with diabetes was in Silesian Voivodeship and amounted to 5.5% (± 0.1%), the second consecutive voivodeship was Łódź with 5.0% (± 0.2%) of people with diabetes and Opole Voivodeship on the third place with 4.9% (0.1%) inhabitants with diabetes. The smallest percentage of people with diabetes was noted in Warmian-Masurian Voivodeship — 3.5% (± 0.1%) and Subcarpathian Voivodeship — 3.6% (± 0.2%).

Conclusions. 1. Average diabetes prevalence rate in Poland in the years 2010–2014 amounted to 4.47% (the assessment was carried out on the basis of the number of people recorded by the National Health Fund as patients with diabetes) or 5.88% (assessment on the basis of the number of people who got their prescriptions filled for reimbursable hypoglycemic agents or glucose meter test strips). 2. Diabetes prevalence in Poland increases in the consecutive years. 3. Prevalence of diabetes varies among voivodeships.
