Analysis of the incidence of newborn's healthcare associated infections and intrauterine infections in several maternity hospitals in Moscow

Purpose of the study. To estimate the incidence of newborn's healthcare associated infections (HAI) and intrauterine infections in the Russian Federation, Moscow and three maternity hospitals in Moscow. Materials and methods. The retrospective epidemiological analysis of neonates HAIs and intrauterine infections during 2008–2017 was performed in the Russian Federation and Moscow and during 2009–2017 in three maternity hospitals (MH) in Moscow. In this study the maternity hospitals would be known as MH № X01, № X02 and № X03. Also, in this study, the calculation and analysis of the proportion of cases of newborn's HAIs and intrauterine infections with laboratory confirmation were performed in Moscow's maternity hospitals. The data was selected from Form № 2 for the Russian Federation and Moscow. Also, the data of the maternity hospitals was drawn from the base of the Hygiene and Epidemiology Center in Moscow. The morbidity rate of HAIs and intrauterine infections of newborns was counted on 1,000 newborns. Microsoft Office Excel 2010 software packages were used for this purpose. The calculation of the increase / decrease rate was made by the method of least squares. Results. The incidence of intrauterine infections and HAIs of newborns in the Russian Federation, Moscow, and maternity hospitals is characterized by the next mutual trends – a significant dominance cases of intrauterine infections' over the cases of HAI, extremely irregular registration and distribution of the nosologies' proportion. Concerning to the dynamics of morbidity during 2009–2017 in maternity hospitals in Moscow, the HAIs newborn's incidence has tendency of decline, and intrauterine infections has considerable increase of the incidence. This consistent pattern is observed in all described maternity hospitals. The structure of the incidence in maternity hospitals is similar to each other. The leading diagnoses among intrauterine infections are intrauterine infection without a lesion and intrauterine pneumonia. The interest of other infections is about 1%. The proportion of cases with laboratory confirmation of the newborn's HAIs and intrauterine infections is extremely small. Besides that, there were identified some indirect signs of poor-quality registration of nosocomial infections. Conclusion. Significant difference in the number of cases of newborn's HAIs and intrauterine infections and their multidirectional incidence trends, once again point to the concealment of a part of nosocomial infections, under such diagnoses, as intrauterine infection without a lesion and intrauterine pneumonia. Laboratory confirmation of cases of HAIs and intrauterine infections in the maternity hospitals is carried out only by a small proportion of patients. Thereby, the incidence rates of HAIs of newborns and intrauterine infections in maternity hospitals in Moscow raise doubts about their reliability.
