[The mortality of adult population from after-troubles of cerebrovascular diseases in the Russian Federation: the territorial differences].

Abstract

The purpose of the study is to investigate trends in adult population mortality from consequences of cerebrovascular diseases (CVD) as primary cause of death in the Subjects of the Russian Federation and the Federal Okrugs (FO) before and during the COVID-19 pandemic.The data from statistical collections The Demographic Yearbook of Russia and The Medical and Demographic Indicators of the Russian Federation for 20192022 was involved into analysis. The statistical and analytical methods were applied. The indicators of the dynamic range were calculated.In the Russian Federation, in 20192022 was noted tendency of decreasing mortality of adult population from aftermaths of cerebrovascular diseases from 30.8 to 23.5 per 100 thousand of corresponding population (the rate of decline 23.7%). The same trend was observed in seven Federal Okrugs (decrease of 20.0% on average), with exception of the North Caucasus Federal Okrug (the growth rate was 8.9%).In the year of the pandemic onset (2020) in the Russian Federation, mortality from consequences of CVD increased by 1,9%. The North Caucasian, Volga, Urals, Siberian, Far Eastern Federal Okrugs demonstrated average increase in mortality up to 12.6%. The Central, North-Western and Southern Federal Okrugs registered average decrease up to 11.9%.The highest mortality of adult population from CVD aftermaths in 2022 was observed in the Amur Oblast (125.3 per 100,000 of the corresponding population) and the Ivanovo Oblast (119.8 per 100,000 of the corresponding population). The lowest value was established in the Republic of Ingushetia (1.7 per 100,000 of corresponding population) and in the Astrakhan Oblast (4.1 per 100,000 of corresponding population).The results of the study demonstrated that before and during the COVID-19 pandemic (20192022) there were territorial differences in the mortality of adult population from CVD aftermaths that may become a prerequisite in further search for decreasing mortality from controllable causes.During the pandemics, decrease of mortality of adult population from CVD was noted only in three Federal Okrugs out of eight (Central, North-Western and Southern).The differences in regions of the Russian Federation can be associated with different approaches in choosing initial cause of death. This fact is to be considered while auditing quality of medical care provision in the Subjects of the Russian Federation and in formation of educational programs for medical personnel involved in drawing up mortality certificates.
