22. European Stroke Conference 531 Epidemiology of stroke Results of three-year-old research of the stroke epidemiology by the territorially populational register method in the Russian Federation, 2009-2011 years.

Pirogov, Moscow, RUSSIAN FED-ERATION2 Stroke stays one of serious medical, social and state problems because of high parameters stroke in-cidence, mortality and case fatality. Background and purposes: Study of epidemiological stroke parameters in the Russian Federation in 2009-2011, in order to organize treatment and acute stroke prevention. Methods: In 2009 the large scale epidemiological stroke research project by method of territorial-ly populational register was begun. This research is counted for 5 years, since 2009 till 2013 year. The main stroke epidemiology parameters of 2009-2011 period are presented by stroke incidence, mortality and case fatality. The research was executed with the Register method. Study of epidemi-ological stroke indexes was conducted in open population of men and women older than 25 years in different regions of Russia. The number of residents was 3477960 in 13 regions in 2011; 3388932 residents in 13 regions in 2010 and 1864932 residents in 10 regions in 2009. Results: According to the European standard, standardized stroke incidence of all types was 3.83 per 1000 population for men in 2009; 4.15 in 2010; 3.75 in 2011. For women stroke incidence of all types was 3.29 per 1000 population in 2009; 2.74 in 2010; 2.67 in 2011. According to the European standard, standardized mortality during first 28 days from the stroke incidence beginning was 1.13 per 1000 population for men in 2009, 1.18 in 2010, 1.06 in 2011. For women mortality was 1.13 per 1000 population for women in 2009; 0.96 in 2010; 0.72 in 2011.Differences in stroke incidence parameters in various regions were brought out. Maximum men’s and women’s stroke incidence parameters were registered in Tatarstan republic 9.28 per 1000 population for men and 5.24 for women, in accordance. Minimum stroke incidence parameters were registered in Dagestan republic 2.20 per 1000 population for men and in Voronezhskaya oblast 1.68 per 1000 for women. Conclusion: During three-year-old period the reliable reduction of women’s stroke incidence and mortality parameters is mentioned.

The quality of a registry is related to the number of sources used to identify patients and to its completeness. Methods A population-based stroke registry recorded patients aged above 15 years in a defined area corre-sponding to a total population of 380000 inhabitants. Hospital surveillance of admissions for stroke included two teaching and one general hospital. Sources: The 6 notification sources were 1) emergency wards of the three hospitals, 2) brain imaging records from radiology units of the hospital or 3) brain imaging records from private practice radiol-ogy units; 4) neurologists and general practitioners; 5) death certificates; 6) hospital based electronic research (ICD9) Inclusion criteria: all neurological deficits lasting at least 1 hour or resolving within one hour but with an abnormal and clinically coherent brain imaging. Capture-recapture method was performed on three sources for non-fatal (1, 2+3, 6) and fatal stroke (1,5, 6)). Incidence was calcu-lated for 100 000 inhabitants. Results For 2008, 2009 and 2010 851, 898, 823 patients were respectively collected. The number of sourc-es per patient was the following for the three combined years: 1 source: 23.1%; 2 sources: 36.0% 3 sources: 28.3%, 4 sources: 10.7%; 5 sources: 1.9% Capture-recapture analysis showed for combined years completeness of 88% for non-fatal stroke, and of 91% for fatal stroke. French standardised cu-mulated incidence was for men: 301, 293 and 278 and for women: 208, 198 and 184 and European standardised cumulated incidence was for men: 197, 196 and 186 and for women: 123, 126 and 113 for 2008, 2009 and 2010 respectively. Discussion High numbers of sources per patient as well as completeness analysis by capture-recapture method show that Brest stroke registry is a reliable population-based stroke data bank for further epidemio-logical studies.
