10-YEAR TRENDS OF MORBIDITY AND MORTALITY FROM CEREBROVASCULAR DISEASES IN THE GRODNO REGION

Stroke and other cerebrovascular diseases (CVDs) are an important medical and social problem due to high mortality and disability of the population. The aim of the study was to analyze the trends of morbidity and mortality in the Grodno region due to stroke and other CVDs over the previous 10-year period based on the data of medical statistics. Material and methods. Information on the number of new cases of CVDs was obtained in the Medical Statistics Section of the Grodno Regional Clinical Hospital. The incidence of CVDs was calculated by I60–I69 ICD-10 codes as the number of newly reported cases per year per 100,000 inhabitants; incidence of stroke – by codes I60–I64. The data on the number of deaths from stroke and other forms of CVDs were obtained from official statistical compilations. Mortality from CVDs was defined as the number of deaths from these diseases per 100,000 inhabitants for a period of 12 months and calculated by codes I60–I69 ICD-10 revision; mortality from stroke – by codes I60–I64. Results. The incidence of CVDs was maximum in 2008 – 862/100,000, then it statistically significantly decreased to 476 in 2014, after which it significantly increased to 557 in 2017. The incidence of stroke in 2008 was 275, then in 2009 it significantly decreased to 242, for a number of years it was about 275, and in 2017 it slightly increased to 285. The mortality from CVDs from the initial value of 189/100,000 increased in 2009 to a value of 197, and then it gradually reduced to the minimum level of 134 in 2014. Subsequently, there was a slight increase in the mortality rate to 143 in 2017. Mortality from stroke changed similarly: a slight increase from the level of 140/100,000 in 2008 to 142 in 2009,followed by a gradual decline to 99 in 2014 and the rise of the index value up to 107 in 2017. Conclusions. According to medical statistics, the incidence of stroke in the Grodno region during 2008–2017 did not change significantly and averaged 269/100,000. The dynamics of the incidence of CVDs during this period with an average value of 578/100,000 was characterized by a significant range of indicators and differed from that for stroke. There was a statistically significant decrease in mortality due to stroke from 140–142 in 2008–2009 to 103–107 in 2016-2017, as well as a statistically significant decrease in mortality due to CVDs from 189–197 in 2008–2009 to 138–143 in 2016–2017 thanks to a set of activities in the implementation of demographic security programs and due to a decrease in the proportion of residents of the region aged 65 and over.
