Introduction.Healthcare-associated infections incidence is one of the most pressing issues in modern healthcare due to their high abundance as well as economic loss they cause.The aimis to study regional features of the incidence of healthcare-associated infections.Methods.We conducted a retrospective epidemiological analysis of nosocomial morbidity in hospitals of the Irkutsk region within 2006-2017 years. We used data, presented in the following state reports: “On the state of sanitary and epidemiological welfare of the population in the Russian Federation”, “On the state of sanitary and epidemiological welfare of the population in the Irkutsk region”.Results and discussion.According to the results of the conducted analysis, it was shown that the average long-term prevalence of healthcare-associated infections in the Irkutsk region was 41.94 ± 2.040/00000 (Russian Federation – 17.49) with a tendency to stabilization in recent years. The therapeutic and prophylactic organizations of the surgical profile have the highest epidemiological significance (over 51 %). At the same time, the share of postoperative complications during the study period decreased by 1.5 times. We have noted a rising trend line with a positive rate of increase in the incidence of nosocomial pneumonia, which in the last two years has taken a leading position in the structure of healthcare-associated infections. The incidence of infections in newborns in the Irkutsk region ranks the third, with a specific weight of 11.54 %. Moreover, if before 2013 purulent-septic diseases of the newborns were the predominant nosological form, in recent years pneumonia has firmly taken over the leadership. During the study period we revealed an increase in the incidence of postpartum endometritis in puerperas. It has been shown that the registration of sepsis, urinary tract infections in the region is low.
