Abstract
Introduction: This study addresses and evaluates the decrease of antibiotic resistance after introduction of a proposed prevention plan and control complex in the intensive care unit (ICU).
 Methods: Data from 1,111 bacteriological analyses, taken from patients who received treatment in the ICU of Ternopil University Hospital from January to August 2015 (group 1) and the same period of 2018 (group II), were included in the study. The complex included measures for the prevention of antibiotic resistance spread and for rational antibiotic use.
 Results: We found that resistance to imipenem changed more than other antibacterial drugs, increased by 60% (р ≤ 0.05), which was conditioned predominantly by Pseudomonas aeruginosa isolates for 100%. A decrease in 39% of polyresistant clinical isolates of Klebsiella pneumoniae in patients of groups I and II showed important prognostic value.
 Conclusion: A complex of the proposed measures included the division of patients in blocks according to the risk of infectious complications, control of antibiotics administration, adherence to sanitary norms by ICU staff, use of sodium hypochlorite resulting in decrease of pathogenic isolates, and level of antibiotic resistance to specific groups of antibacterial drugs.

This study addresses and evaluates the decrease of antibiotic resistance after introduction of a proposed prevention plan and control complex in the intensive care unit (ICU)
After the analysis of the obtained data, we found that the amount of Klebsiella pneumoniae strains isolated from group II patients decreased by 39 % (p ≤ 0.05), when compared to the group I patients (Figure 1)
Aeruginosa, we found that the prevalence of these microorganisms in group II patients decreased by 17 % (p ≤ 0.05), when compared to group I patients (Figure 2)
Summary
This study addresses and evaluates the decrease of antibiotic resistance after introduction of a proposed prevention plan and control complex in the intensive care unit (ICU). Conclusion: A complex of the proposed measures included the division of patients in blocks according to the risk of infectious complications, control of antibiotics administration, adherence to sanitary norms by ICU staff, use of sodium hypochlorite resulting in decrease of pathogenic isolates, and level of antibiotic resistance to specific groups of antibacterial drugs. One of the critical needs is to decrease of risk of formation and spread of nosocomial strains of microorganisms which have resistance to antimicrobials. Steps to address this are the development and implementation of an effective program of infection control in hospitals 7
