Abstract
A new global
threat announced by the World Health Organization on March 11, 2020, caused by
the pandemic spread of novel coronavirus infection has become a real concern
for the humanity wellbeing. Quantitative assessment of the detriment caused by
the pandemic is relevant to raise the awareness of healthcare system, and helps
to understand the effectiveness of anti-epidemic measures. The methodology of
assessment of the overall mortality attributed to the presence of COVID-19
pandemic, unlike the use of specific indicators which are sensitive to
different methods of accounting the number of infected and fatal cases,
provides more clear understanding of the pandemic-related detriment.
The population changes
in small nuclear city in the South Urals of Russian Federation have been
analyzed during the decade based on the open-source demographic data to
quantify the pandemic-related detriment, realized in excess overall mortality.
The overall mortality has been compared to the previous 10 non-pandemic years
using additive model of excess absolute risk. The number of absolute excess
deaths, adjusted by sex, age, population size and the number of diseased has
been calculated using multiparametric linear regression. The relationship between
the number of overall deaths and the number of diseased with COVID-19, reported by the healthcare officials, has
been analyzed. Total predicted biennial excess of overall deaths attributed to
the pandemic was 557.9 cases among total 90,000 population. A total predicted
pandemic-related excess death per 1,000 of diseased was 50.2 (95% CI 38.4;
62.0).
Further monitoring of the epidemic situation in the nuclear city is
necessary to develop an effective strategy to control and prevent the consequences of
COVID-19. Major affords will be made in the upcoming
research to understand the role of ionizing radiation and other risk factors such as
cancer in the increase of pandemic-related mortality.
