Site-specific, risk-adjusted incidence rates of intensive care unit (ICU)-acquired infections were obtained through standardized surveillance in 8 ICUs in Greece. High rates were observed for central line-associated bloodstream infection (12.1 infections per 1,000 device-days) and ventilator-associated pneumonia (12.5 infections per 1,000 device-days). Gram-negative microorganisms accounted for 60.4% of the isolates recovered, and Acinetobacter species were predominant. To reduce infection rates in Greek ICUs, comprehensive infection control programs are required.

Objectives.To examine the relative proportions of central line-associated bloodstream infection (BSI) due to gram-negative bacteria and due to gram-positive bacteria among patients who had undergone surgery and patients who had not. The study also evaluated clinical predictive factors and unadjusted outcomes associated with central line-associated BSI caused by gram-negative bacteria in the postoperative period.Design.Observational, case-control study based on a retrospective review of medical records.Setting.University of Chicago Medical Center, a 500-bed tertiary care center located on Chicago's south side.Patients.Adult intensive care unit (ICU) patients who developed central line-associated BSI.Results.There were a total of 142 adult patients who met the Centers for Disease Control and Prevention National Nosocomial Infection Surveillance System definition for central line-associated BSI. Of those, 66 patients (46.5%) had infections due to gram-positive bacteria, 49 patients (34.5%) had infections due to gram-negative bacteria, 23 patients (16.2%) had infections due to yeast, and 4 patients (2.8%) had mixed infections. Patients who underwent surgery were more likely to develop central line-associated BSI due to gram-negative bacteria within 28 days of the surgery, compared with patients who had not had surgery recently (57.6% vs 27.3%; P = .002). On multivariable logistic regression analysis, diabetes mellitus (adjusted odds ratio [OR], 4.6 [95% CI, 1.2-18.1]; P = .03) and the presence of hypotension at the time of the first blood culture positive for a pathogen (adjusted OR, 9.8 [95% CI, 2.5-39.1]; P = .001 ) were found to be independently predictive of central line-associated BSI caused by gram-negative bacteria. Unadjusted outcomes were not different in the group with BSI due to gram-negative pathogens, compared to the group with BSI due to gram-positive pathogens.Conclusions.Clinicians caring for critically ill patients after surgery should be especially concerned about the possibility of central line-associated BSI caused by gram-negative pathogens. The presence of diabetes and hypotension appear to be significant associated factors.

Background: Central line–associated bloodstream infections are serious life-threatening infections in the intensive care unit setting. Methods: To analyze the impact of the International Nosocomial Infection Control Consortium (INICC) Multidimensional Approach (IMA) and INICC Surveillance Online System (ISOS) on central line–associated bloodstream infection rates in Bahrain from January 2013 to December 2016, we conducted a prospective, before-after surveillance, cohort, observational study in one intensive care unit in Bahrain. During baseline, we performed outcome and process surveillance of central line–associated bloodstream infection on 2320 intensive care unit patients, applying Centers for Disease Control and Prevention’s National Healthcare Safety Network definitions. During intervention, we implemented IMA through ISOS, including (1) a bundle of infection prevention interventions, (2) education, (3) outcome surveillance, (4) process surveillance, (5) feedback on central line–associated bloodstream infection rates and consequences, and (6) performance feedback of process surveillance. Bivariate and multivariate regression analyses were performed using a logistic regression model to estimate the effect of the intervention on the central line–associated bloodstream infection rate. Results: During baseline, 672 central line days and 7 central line–associated bloodstream infections were recorded, accounting for 10.4 central line–associated bloodstream infections per 1000 central line days. During intervention, 13,020 central line days and 48 central line–associated bloodstream infections were recorded. After the second year, there was a sustained 89% cumulative central line–associated bloodstream infection rate reduction to 1.2 central line–associated bloodstream infections per 1000 central line days (incidence density rate, 0.11; 95% confidence interval 0.1–0.3; p, 0.001). The average extra length of stay of patients with central line–associated bloodstream infection was 23.3 days, and due to the reduction of central line–associated bloodstream infections, 367 days of hospitalization were saved, amounting to a reduction in hospitalization costs of US$1,100,553. Conclusion: Implementing IMA was associated with a significant reduction in the central line–associated bloodstream infection rate in Bahrain.

Background: Until the 1980s, central vascular access in the Neonatal Intensive Care Unit was predominantly delivered by umbilical catheters and only and if needed by surgical cutdowns or subclavian vein catheterization through blind percutaneous venipuncture. In the early 1980s, epicutaneo-caval catheters were successfully introduced. Methods: In our Neonatal Intensive Care Unit, a dedicated team to insert epicutaneo-caval catheters was formally established in January 2017, including 12 neonatologists and 1 neonatal nurse practitioner. A before- versus after-intervention study was designed to determine whether the establishment of the epicutaneo-caval catheter insertion team is associated with increased success rates and a decreased risk of catheter-related complications. Success rates and other catheter-related parameters were traced from 2016 onward. Collected data were analyzed for three consecutive years: 2016, 2017, and 2018. Results: The epicutaneo-caval catheter team inserted 1336 catheters over 3 years. Both first prick (from 57.7% to 66.9%; p = 0.023) and overall success (from 81.7% to 97.6%; p < 0.0001) rates significantly improved. In 2018, the number of tunneled or surgically inserted central venous catheters came down to zero (p < 0.0001). Overall catheter-related complications were significantly lower following the epicutaneo-caval catheter team’s establishment (p < 0.0001) while there was no significant decrease noted (p = 0.978) in central line–associated bacterial stream infection rates. Conclusion: A dedicated epicutaneo-caval catheter team is a promising intervention to increase success rates and significantly decrease catheter-related complications in Neonatal Intensive Care Unit. Standardizing epicutaneo-caval catheter placement is important; however, standardizing catheter maintenance seems essential to the improvement of central line–associated bacterial stream infection rates.

ABSTRACT ANTIBIOTIC RESISTANCE OF NON - FERMENTABLE GRAM - NEGATIVE BACTERIA CAUSING PNEUMONIA IN PATIENTS WITH MECHANICALLY VENTILATION Background: Ventilator - associated pneumonia is a very common nosocomial infection in the intensive care unit. Many bacteria cause ventilator - associated pneumonia, in which non - fermentative Gram - negative bacteria such as Acinetobacter baumannii, Pseudomonas aeruginosa, etc., are the leading pathogens and have high antibiotic resistance. Methods: A cross sectional descriptive study was conducted on non - fermentative bacteria strains causing ventilator - associated pneumonia which were isolated at the Surgical Intensive Care Unit Department of Nghe An General Friendship Hospital from January 2020 to June 2021. Results: A total of 120 strains of non - fermenting Gram - negative bacteria were isolated. Of these, 85 strains were Acinetobacter baumannii, 31 strains was Pseudomonas aeruginosa. Acinetobacter baumannii has a resistance rate of more than 70% with all tested antibiotics, of which the highest resistance is to Ceftriaxone 96.9%. Pseudomonas aeriginosa was resistant to all tested antibiotics, with the highest resistance to Gentamycin80.0%, the lowest resistance to Piperacillin/Tazobactam 32.3%. Conclusion: Non - fermentative bacteria are the main pathogens of ventilator - associated pneumonia. The most common pathogens were Acinetobacter baumannii and Pseudomonas aeruginosa. These bacteria were highly resistant to the tested antibiotics. In which, A. baumannii resisted over 70% of the tested antibiotics, and P. aeruginosa resisted all tested antibiotics with varying degrees from 32.3 to 80.0%. Keywords: Ventilation associated pneumonia, VAP, P. aeruginosa, A. baumannii.
