Abstract

This paper presents an approach to implementing institution-wide surveillance of healthcare-associated infections by means of regular point-prevalence surveys. We explain the methods of data collection and statistical analysis in details. Healthcare-associated infections are defined as localized or systemic conditions which was not present on admission or within the first 48 hour of hospital stay (or 30 days for surgical site infections). The prevalence of different categories of healthcare-associated infections varies in different hospitals that can be explained by variations in hospital stocks, types of medical units, treatment, age of patients and others. According to different published sources, the incidence of healthcare-associated infections in Russia exceeds the official data. An inconstancy in published results probably indicates under-registration of healthcare-associated infections and demonstrates a need for alternative surveillance measures to provide a basis to enhance the practice of infection control. Repeated prevalence surveys are known as simple surveillance options, which are efficiently used in the European countries. This method allows to obtain data on prevalence of different categories of healthcare-associated infections and factors associated with occurrence of infections in different hospital units. The results allows to identify areas requiring improvement in the hospital and develop specific prevention strategy for every hospital unit.

Иях интенсивной терапии чаще регистрируются пневмонии и сепсис, в терапевтических отделениях - инфекции мочевыделительной системы, а в детских стационарах - вирусные гастроэнтериты [6, 8, 13, 18]. Факторами риска ИСМП, по данным разных авторов [6, 17-19], являются возраст младше года, длительность госпитализации более 6 дней, переполненность палат, использование мочевых и венозных катетеров, однако факторы риска могут варьировать в зависимости от ти
