Analysis of risk for infections related to providing medical assistance

Our research goal was to assess risks for infections related to providing medical assistance in places where air samples conform or don't conform to hygienic standards as per microbiological parameters. We performed bacteriological and mycological examination of air samples (n=44) in a medical organization (inside it) in conformity with methodical guidelines "Techniques for sanitary-bacteriologic examination of environmental objects, air, and sterility control in medical organizations" and sanitary rules and standards "Sanitary-epidemiologic requirements to organizations dealing with medical activities". We identified all types of microorganisms detected in air samples using conventional microbiological techniques. Bacteria belonging to 3 families, 4 stems, and 7 species, were detected in samples deviating from standards; bacteria of 7 families, 9 stems, and 12 species, were detected in samples conforming to standards. We found a great species variety of molds and bacteria such as staphylococcus spp., Micrococcus spp., Acinetobacter spp., Neisseria spp., Pausterella spp., Stenotrophamonas spp., which were considered to be conditionally pathogenic and causing infections related to providing medical assistance. We calculated relative risks parameters for infections caused by various microorganisms. We revealed that risks for infections caused by staphylococcus were higher in rooms where air samples didn't conform to sanitary-hygienic standards than in "clean rooms" (RR=2.1; OR=3.6). Risks for infections caused by micrococcus and molds were still substantially high both in "clean" rooms and in rooms where air samples didn't conform to sanitary-hygienic standards (). All this makes it absolutely necessary to improve activities aimed at monitoring infections related to providing medical assistance and caused by bacterial and mycotic agents as well as to develop existing hygienic standards and to apply new advanced disinfectants.
