Prevalence of hospital pneumonia caused by antibiotics resistant microorganisms In different intensive care units

Introduction. Hospital pneumonia (HP) is lower respiratory tract infectious disease, which is diagnosed when pneumonia symptoms are diagnosed after 48 hours after being hospitalized. Hospitalized pneumonia in the intensive care unit is associated with high rates of morbidity and mortality due to the critical state of patients and the high prevalence of antibiotic-resistant microorganisms in hospitals. Aim. The aim of this research was to evaluate the prevailing aetiology of hospital pneumonia in the LSMU KK Cardiac Surgery and Central intensive care units. Also, compare the antibiotic resistance of the most commonly occurring pathogens of hospital pneumonia in different intensive care units. Materials and methods. This study was carried out at LSMU KK Cardiac Surgery and Central intensive care units ICU. For the analysis, 1009 patients were retrospectively selected, for whom in 2015–2016 hospital pneumonia was diagnosed. Results. The most common microorganisms causing HP in the Central and Cardiosurgical ICU were Enterobacteriaceae spp. 30.23 % and 38.42 % respectively, Acinetobacter spp. 20.04 % and 15.7 %, Pseudomona aeriginosa 11.81 % and 21.57 %. Antimicrobial resistance in central ICU was identified: Enterobacteriaceae spp. resistance was Cefuroxime 46.6 %, Cefotaxis 34.5 %, Ciprofloxacin 28.2 %; Acinetobacter spp. – Ciprofloxacin 94.9 %, Meropenem 90.8 %, Imipenem 90.8 %; Pseudomona aeruginosa – Ciprofloxacin 15.7 %, Gentamicin 9.8 %, Amikacin 5.9 %. Antimicrobial resistance was evaluated in the cardiac surgery ICU as well: Enterobacteriaceae spp. – Cefuroxime 54.8 %, Cefotaxis 37.6 %, Ciprofloxacin 33.3 %; Acinetobacter spp. – Ciprofloxacin 100 %, Meropenem 92.1 %, Imipenem 92.1 %; Pseudomonas aeruginosa – Gentamicin 10.5 %, Ciprofloxacin 7.0 %, Amikacin 7.0 %. Conclusion. The prevailing hospital pneumonia agents in the Central and Cardiac Surgery intensive care units are Enterobacteria[...]
