RUSSIA-WIDE EPIDEMIOLOGICAL SURVEY OF CONGENITAL AND NOSOCOMIAL INFECTIONS IN NEWBORNS

High prevalence and great socio-economic impact of nosocomial infections is documented in obstetric hospitals. Objective: to uncover Russia-wide epidemiological features for congenital and nosocomial infections in newborns. Material and Methods: the data covering 2008-2016 period were retrieved from the Federal Statistical Monitoring Form No. 2 "Report on Infectious and Parasitic Diseases", via the Unified Interdepartmental Information Statistical System. During 2008-2016, incidence of congenital and nosocomial infections in newborns was analyzed in various constituents of the Russian Federation, which were divided into quartile groups including confidence interval. Results: It was found that the increased/decreased/unchanged incidence of congenital infections in newborns was shown in 30, 31 and 13 subjects, respectively. In case of nosocomial infections in newborns, its incidence was increased/decreased/unchanged in 7, 41 and 26 subjects, respectively. Moreover, a congenital/nosocomial infection ratio in newborns was increased/decreased/unchanged in 40, 15 and 19 subjects, respectively. Based on the morbidity pattern, 9 major groups might be distinguished. In particular, the most abundant (16 subjects) was the group with increased incidence of congenital infections, decreased incidence of nosocomial infections and increased congenital/nosocomial infection ratio in newborns. However, it is worth mentioning that recording of nosocomial infection cases is incomplete in the vast majority of the subjects of the Russian Federation: as few as seven subjects may be highlighted providing a proper registration of nosocomial and congenital infections in newborns such as: Vologda Region, Trans-Baikal Territory, Nizhny Novgorod Region, Omsk Region, Orenburg Region, Penza Region, and Sverdlovsk Region. Conclusion: to fully assess an objective status on nosocomial and congenital infections in newborns, it is necessary that a hospital epidemiologist investigates every single case; ensure applying a standard approach to determine a case of healthcare-associated infection, congenital infections; official recording of all cases; responsibility of all staff members involved in recording healthcare-associated infection cases; regularly reviewed data by using science-based methods.
