Assessment of mortality from traumatic subdural hemorrhage in Kazakhstan

Traumatic brain injury (TBI) is one of the most severe and common forms of damage to the central nervous system. At the same time, traumatic subdural hemorrhage refers to severe TBI leading to severe disability and death. Aim of the research. To study the epidemiological features of mortality from traumatic subdural hemorrhage in Kazakhstan. Material and Methods. The study was retrospective, 2009-2018, the material was data on cases of death from traumatic subdural hemorrhage in the country, descriptive and analytical methods of epidemiology were used. Results and discussion. It is established that the average age of those who died from traumatic subdural hemorrhage in men (44.5±0.78 years) was younger than in women patients (47.6±1.17 years). The crude and standardized mortality rates for men (1.33±0.070/0000 and 1.39±0.070/0000, respectively) were higher than for women (0.45±0.040/0000 and 0.42±0.040/0000, respectively). Age indicators had a unimodal increase with a peak of mortality in the group of 70 years and older in both men (2.8±0.38) and women (1.05±0.14). Trends in age-related indicators in men and women tended to increase, with the most pronounced growth rates of the equalized indicators being at the age of 70 years and older in men (Tgr=+7.1%), and in women (Tgr=+9.2%). Conclusions. The analysis of mortality from traumatic subdural hemorrhage indicates a gender difference and an increase in mortality in all the studied population groups. The obtained data are recommended to be used for monitoring and evaluation of diagnostic and therapeutic measures in this pathology. Keywords: traumatic subdural hemorrhage, mortality, Kazakhstan
