Dynamics of mortality rates in different types of stroke in the territories included in the Federal program of reorganization of care for stroke patients

Abstract

To study and analyze the dynamics of one-day, 7-day and 28-day mortality rates in different types of stroke. The retrospective study was based on the data of the territorial population register for 2009-2016 from seven territories of the Russian Federation in which the Federal program of reorganization of care for stroke patients came into force in 2009. The study population included men and women, aged 25 years and older, registered in the study area. A total of 29.779 stroke cases were identified. The mortality rate was calculated as the ratio of the number of stroke cases that ended fatally to the number of stroke cases per year. The dynamics of the mortality rate of the following types of stroke was analyzed: subarachnoid hemorrhage (SAH), intracerebral hemorrhage (ICH) and ischemic stroke (IS). Between 2009 and 2010, there was an increase in SAH one-day, 7-day and 28-day mortality rates and in ICH one-day, 7-day mortality rates. In the period from 2009 to 2010, the increased ICH 28-day mortality rates tended to increase, while the IS one-day, 7-day and 28-day mortality rates decreased. One-day, 7-day and 28-day mortality rates in SAH, ICH, IS had a declining trend from 2010 to 2016. A slight increase in SAH one-day mortality rate in 2014 and 2015 and SAH 7-day mortality rate in 2013 was observed. The same trend was noted for ICH mortality rates in 2013 and 2016 and in 2013, respectively. The IS one-day, 7-day and 28-day mortality rates slightly increased in 2014. According to the territorial-population register from 2009 to 2016, a significant decrease in one-day, 7-day and 28-day mortality rates in all types of stroke in the studied territories was registered. There is no doubt that this is due to the successful implementation of the Federal program of reorganization of care for stroke patients carried out in this period in the territories included in the study.
