<p>Hospital-acquired bacterial pneumonia (HABP) is one of the most important causes of morbidity, mortality and economic problems especially for patients admitted in the intensive care unit (ICU) ward. The aim of this study was to determine the incidence of nosocomial pneumonia in ICU, identify the causative bacteria and their resistance profiles. This cross sectional study was performed on 214 patients who were admitted in the ICU ward of a general hospital requiring mechanical ventilation for at least 48 h. Identification of HABP was based on the clinical signs manifested 48 h or more after admission, new chest X-ray infiltrates and microbiologic examination of endo tracheal secretion. Data were analyzed using SPSS 21 to perform the descriptive statistics. The isolated gram negative bacteria were <em>Klebsiella pneumoniae</em> (50%), <em>Staphylococcus aureus</em> (18.7%), <em>Acinetobacter baumannii</em> (12.5%), <em>Escherichia coli</em> (12.5%) and <em>Pseudomonas aeroginosa</em> (6.3%). The maximum antimicrobial resistance of gram negative bacteria was to Cefazolin (100%) and Ampicillin (84.6%), while antimicrobial resistance to Clindamycin, Azithromycin, Amoxycillin+clavulanate, Trimethoprim+sulfamethoxazole and Ciprofloxacin was 33.3%. No resistance was seen towards carbapenems.The most frequent gram negative isolated bacterium was <em>K. pneumoniae, </em>and maximum antimicrobial resistance rate was observed for Cefazolin and Ampicillin, which is due to betalactamase production.</p>

Resistance Rates

Background: The aim of our study was to evaluate the antimicrobial resistance rates among pathogen microorganisms especially colistin resistant rates of Acinetobacter baumannii in intensive care unit (ICU)-acquired infections and to determine infection-specific correct treatment strategies. Methods: The data of adult and newborn infant patients diagnosed with ICU-acquired infection in a tertiary education and research hospital in Bursa in 2014 and 2016 were analyzed, retrospectively. Results: Acinetobacter baumannii was the most frequent pathogen of ICU-acquired infections in 2014 and 2016. There was a significant increase in colistin (CO) resistance rates in A. baumanii (0.0%-6.8%). A significant increase in CO, cefepime (FEP), ciprofloxacin (CIP) resistance rates was established in all gram negative bacteria (0.0%-7.9%, 50.0%-91.9%, 54.7%-74.6%), respectively. A significant increase in the rate of detection of A. baumanii as the pathogen microorganism in respiratory tract infection (RTI) was established (53.9% -79.5%). In addition, the average ventilator-associated pneumonia (VIP) infection rate also increased in 2016 compared to 2014 (VIP rate 2014: 7.12, 2016: 7.45, per 1000 ventilator days). A significant decrease in the rate of detection of all gram negative microorganisms in the surgical site infection (SSI), and a significant increase in the rate of detection of all gram positive microorganisms in the SSI was determined. Conclusion: Increased antimicrobial resistance, especially increased colistin resistance rates in ICU-acquired infections, necessitates the creation of new strategies in empirical therapy. Detection of antimicrobial resistance profiles of local and infectious pathogen microorganisms in ICUs is a good guide for correct antimicrobial management.

Background. Hands of healthcare workers (HCWs) are vehicles for pathogens responsible for healthcare-associated infections (HAIs). Following the identification of Gram-negative organisms (GNOs) in all cases of HAIs in the cardiac intensive care unit (ICU), we sought to determine the burden of hand colonization with GNOs among healthcare workers who access the cardiac ICU. Methods. We retrospectively reviewed results from surveillance cultures of fingertip imprints of HCWs who access the cardiac ICU at the Uganda Heart Institute. We collected data on staff category, isolates, and susceptibility to antibiotics. We analyzed the data using Microsoft Excel, and the results are summarized in proportions and percentages and presented in charts and tables. Results. Fifty-six healthcare workers participated in the surveillance. 21 were ICU clinicians, 21 non-ICU clinicians, and 14 nonclinicians. GNOs were cultured in 19 (33.9%) HCWs, in which 8/19 (42.1%) were non-ICU clinicians, 6/19 (31.2%) ICU clinicians, and 5/19 (26.3%) nonclinicians. 32 isolates were identified, of which 47%, 28%, and 25% were cultured from non-ICU clinicians, nonclinicians, and ICU clinicians, respectively. Predominant isolates were Acinetobacter (34%), Citrobacter (21.9%), and Pseudomonas (21.9%). Antimicrobial resistance ranged from 4% to 90%. 9/28 (32.1%) isolates, predominantly Acinetobacter species (spp), were carbapenem resistant. 8/28 (28.6%) isolates, predominantly Citrobacter spp, were multidrug resistant. Resistance to ciprofloxacin and cefepime was low at 3.6% and 4.4%, respectively. Conclusion. Gram-negative organisms, predominantly Acinetobacter, Citrobacter, and Pseudomonas spp, were prevalent on the hands of HCWs who access the cardiac ICU irrespective of the staff category. Antimicrobial resistance was high, with multidrug resistance and carbapenem resistance common among Citrobacter spp and Acinetobacter spp, respectively. Resistance to cefepime and ciprofloxacin was low.
