“…In the study conducted by Cisneros and Rodríguez-Baño (2002) they found that many isolates of Acinetobacter species were resistant to almost all antibiotics routinely used in the ICUs of their hospital. In the antibiotic sensitivity studies conducted in Pakistan resistance rates of A. baumannii are reported as 32-100% against ciprofloxacin, 91-100% against Cefepime, 90-92% against Piperacillintazobactam, 24-94% against Amikacin and 18-85% against Gentamycin (Gozutok et al, 2013). It is in support of our study which showed minimum resistance against Gentamycin and Amikacin.…”

“…Based on the national nosocomial infections surveillance network (NNISN) 2020 report on causative organisms and antibiotic resistance, the rate and density of HAIs were 0.58 and 0.90.8 In our study, the surveillance data for medical ICU encompassing 2019 and 2020 showed a nosocomial infection rate of 5.1 and density of 7.78 9 . Pneumonia is the most common type of HAIs in ICUs, with a reported VAP incidence of 40.7% to 52.5% [10][11][12] . On the other hand, the most common type of ICU infection in Ak et al's and Akalın et al's studies was bacteriemia, with respective incidence rates of 36.3% and 34.4% 8,13 .…”

Objective: This study was undertaken to assess the current status of healthcare associated infections (HAIs) in our institution during a 2-year period in relation to causative agents and their distribution, use and duration of invasive mechanical ventilation, and infection rate and incidence in comparison with national data. Methods: Patients admitted to Medical ICUs of Meram State Hospital between 1st Jan 2019 and 31st Dec 2020 wereincluded. During a 2-year period a total of 47 patients were diagnosed with HAIs based on Centers for Disease Control and Prevention (CDC) and National Nosocomial Infection Surveillance Network (NNISN) criteria. Results: During 6041 follow-up days for 922 patients admitted to ICU, a total of 47 HAIs cases were detected. The most common types of HAIs included healthcare-associated pneumonia in 21 patients (45.6%) and other infections of the respiratory system in 12 patients (26.1%). The most common causative agent was Acinetobacter baumannii, which was found in 27 patients (50.9%). Conclusion: HAIs is an unavoidable condition in ICUs owing to a number of factors such as frequent use of invasive devices, prolonged length of admission, and increased number of complications. One of the major health targets in healthcare facilities is to control an manage HAIs. Avoidance from unnecessary catheterizations, timely removal of invasive catheters, increased adherence to infection control measures, prevention of inappropriate antibiotic use, compliance with isolation procedures, and initiation of appropriate antibiotherapy based on documentation of causative organisms will significantly reduce HAIs incidence.

“…It is known that in carbapenems, which are the most broad-spectrum β-lactam antibiotics developed for use in highly resistant strains, the main resistance mechanism is carbapenemase production, other mechanisms are modification of penicillin-binding proteins and loss of porin (13). Especially in recent studies, high levels of carbapenem resistance have been found in Acinetobacter, Pseudomonas, Klebsiella species (24)(25)(26). In our study, while carbapenem resistance was found to be quite high for A. baumannii, Klebsiella spp, and P. aeruginosa, colistin resistance was found to be lower for all species.…”

Objective:The aim of this study was to evaluate the antimicrobial resistance rates of bacteria isolated from the samples of catheter and endotracheal aspirates (ETS) of patients under mechanical ventilation in intensive care units (ICUs). Material and Methods:We determined the antibiotic resistance rates of bacteria isolated from catheters and ETS taken from patients who underwent mechanical ventilation in the ICUs at the Siirt Training and Research Hospital between January 2018 and November 2019.Results: While the most common Gram-positive bacteria isolated from catheters and ETS were coagulase-negative Staphylococcus (CNS), Staphylococcus aureus, Streptococcus pneumoniae, and Enterococcus faecium, and the most common Gram-negative bacteria were Acinetobacter baumannii, Klebsiella spp., Pseudomonas aeruginosa and Escherichia coli. Among Gram-positive bacteria, methicillin resistances were detected in 82.9% of CNS isolated from catheter and in 45% of S. aureus strains isolated from ETS. Vancomycin resistance was observed in 14.3% of E. faecium. Carbapenem resistance rates were 100% for A. baumannii in both catheter and ETS while colistin resistance rates were 16.7% and 7.7% for catheter and ETS, respectively. For Klebsiella spp., carbapenem resistance rates were 47.1% and 59.1% in catheter and ETS, respectively, while colistin resistance rates were 23.5% in catheter and 9.1% in ETS. For P. aeruginosa, carbapenem resistance rate was 58.8% and colistin resistance rate was 2.9% in ETS. Carbapenem resistance rate of E. coli isolated from ETS was 11.1% while 100% of E. coli samples were sensitive to colistin. Conclusion:It should be noted that infections that develop in patients followed in ICUs often occur with multiple resistant microorganisms. Antimicrobial resistance patterns of the factors detected in ICUs should be monitored regularly and treatment protocols should be updated accordingly.
