INTRODUCTION: Central venous catheter (CVC) placement is an unavoidable part of the everyday medical practice. At the same time CVC application is associated with high risk of development of central line-associated bloodstream infections (CLABSIs). These infections are cause of icreased morbidity and mortality rates as well as higer costs of the inpatient treatment2. Risk factors for onset of CLABSIs include duration of catheterization, length of hospital stay before catheterization, anatomic site of placement, CVC placement at the intensive care units (ICU), parenteral nutrition (PN) and ommisions diring CVC placement, use and care. CLABSI incidence rates vary depending on distribution of different risk factors associated with CVC and patient him/herself. The most significant causative organisms of CLABSIs are coagulase-negative Staphylococcocae, Staphylococcus aureus (S.aures), Enterococcus spp. i Candida spp. CLABSIs prevention measures include compliance with the rules of the aseptic technique upon placement, use and care of CVCs, which, based on the study results, may enable prevention of 65% to 70% of cases of CLABSIs. METHODS: A prospective cohort study included 200 patients hospitalized at the intensive care and therapy units of the CCS Clinic of Digestive Surgery in the period November 30th, 2006-November 31st, 2007 in whom CVC was placed for more than 48 hours. All the data necessary for the study were obtained based on the review of the case histories and they were recorded into the individual questionnaires for each patient. The questionnarire included patient information (age, gender, underlying disease, presence of other infections), information related to diagnostic and therapeutic procedures to which the patient was exposed. The incidence of CRBSIs in ICU patients, Institute of Digestive Diseases, CCS over the study period was 10.08 per 1,000 catheter-days. During the study CLABSI more often present in the females. Additionally, application of albumin and amino acids, ICU stay longer that 7 days and CVC application longer than 15 days, significantly more often present in patients with CRBSIs than in the group of patients without CRBSIs. Independent factors for development of CRBSI are gender, administration of albumin and amino acids. The most common microorganisms isolated from hemocultures and CVC were S. aureus and Klebsiella spp., with 31,8% of isolates each. Statistically significant difference was evidenced in frequency of resistance of S. aureus isolates to methicillin in the group of patients with CRBSI in comparison to the group of patients without CLABSIs. CLABSIs prevention measurs include compliance with the rules of the aseptic technique upon placement, use and care of CVCs.

Abstract Background Despite successful implementation of evidence-based prevention bundles, central line-associated bloodstream infections (CLABSIs) continue to occur in neonatal intensive care units (NICUs). We hypothesized that multi-disciplinary prevention rounds may be able to further reduce CLABSIs. Methods We implemented bedside rounds in a 39-bed tertiary NICU in November 2018 with the focus of reducing CLABSIs. Standardized rounds for all patients with a central venous line (CVL) occurred 2–3 times/week on weekdays during either the day or evening shifts. Rounds included NICU nursing leadership, the Hospital Epidemiologist and the patient’s nurse. Questions focused on the CVL maintenance bundle, reducing line access, and patient-specific CLABSI risk factors. Best practices were reinforced and solutions for identified risk factors were developed. Recommendations were communicated to the physician, as appropriate. Prevention rounds data were collected. Nurses and providers in the NICU were surveyed about their perceptions of the rounds. CLABSIs were identified by Infection Prevention using standard definitions. Results The average daily NICU census was 35.6, with an average of 14 patients with CVLs/day. The average duration of rounds was 45 minutes. Recommendations to physicians, such as changing medications from intravenous to oral or line removal, were accepted 85% of the time. 74.5% of nurses and 87.5% of providers thought that prevention rounds had at least some impact on CLABSI prevention. Nurse and provider responses to the perceived impact of CLABSI prevention rounds are in Tables 1 and 2, respectively. In the 12 months prior to starting prevention rounds, the CLABSI rate was 1.53 /1000 line days and the CLABSI rate for the 6 months after starting rounds was 0.99/1,000 line days, a 65% decrease. Conclusion CLABSI prevention rounds helped reinforce evidence-based prevention practices, identified patient-specific risk factors and improved physician-nurse communication. CLABSIs in NICU were reduced. Disclosures All authors: No reported disclosures.

Abstract Background : Fungal bloodstream infections (FBI) among intensive care unit (ICU) patients are increasing. Our objective was to characterize the fungal pathogens that cause bloodstream infections and determine the epidemiology and risk factors for patient mortality among ICU patients in Meizhou, China. Methods Eighty-one ICU patients with FBI during their stays were included in the study conducted from January 2008 to December 2017. Blood cultures were performed and the antimicrobial susceptibility profiles of the resulting isolates were determined. Logistic multiple regression and receiver operating characteristics (ROC) curve analysis were used to assess the risk factors for mortality among the cases. Results The prevalence of FBI in ICU patients was 0.38% (81/21,098) with a mortality rate of 35.8% (29/81). Ninety-eight strains of bloodstream-infecting fungi, mainly Candida spp., were identified from these patients. Candida albicans was most common (42.9%). Two strains of C. parapsilosis were no-sensitive to caspofungin, C. glabrata were less than 80% sensitive to azole drugs.. Logistic multiple regression showed that age, serum albumin, Acute Physiology and Chronic Health Evaluation (APACHE) II score, three or more underlying diseases, and length of stay in ICU were independent risk factors for mortality in FBI. ROC curve analysis showed that APACHE II scores > 19 and serum albumin ≤ 25g/L were the best predictors of mortality. Conclusion Candida spp. predominated with high mortality rates among cases of FBI in ICU. Thus, clinical staff should enhance overall patient monitoring and especially monitor fungal susceptibility to reduce mortality rates.

Objective: The study aimed to measure the incidence, risk factors and most frequent causative organisms of central line-associated bloodstream infections (CLA-BSI) in the Medical/Coronary and Surgical Intensive Care Units (ICUs) at a private hospital. Methods: This prospective study included 499 patients and was conducted between April 2014 and September 2014 in the Medical/Coronary ICU and Surgical ICU of a private hospital in Cairo, Egypt. Results: Approximately 44% of all the patients admitted to the ICUs underwent Central Venous Catheter (CVC) insertion. The overall incidence density rate of CLA-BSI was 6 cases per 1000 central line-days. The central line utilization rate was 0.94 per 1000 patient-days. The mortality rate among cases with CLA-BSI was 16.8% (95% CI: 13.6% – 20.4%) during the study period. Risk factors for CLA-BSI were detected by univariate analysis and included associated co-morbidities such as heart failure, APACHE II scores of >15, an ICU stay of 5 days or more, duration of CVC placement, subclavian insertion of CVCs, and mechanical ventilation. Additionally, logistic regression analysis identified a long ICU stay of 5 days or more, mechanical ventilation and the presence of heart failure as the only significant predictors. Gram-negative bacteria, especially Enterobacter (36.8%: 95% CI: 16.3%– 61.6%), Pseudomonas aeruginosa (21.1%: 95% CI: 16.0% - 45.5%) were the predominant organisms detected in CLA-BSI cases. Conclusion: CLA-BSI is an important cause of mortality in ICU patients. The infection rate is considerably higher than that in recent studies from developed counties, but it is still lower than the rates reported in comparable published studies in Egypt. Strict adherence to the standard infection prevention practices for critically ill patients is highly recommended.

SUMMARYCentral line-associated bloodstream infections (CLABSIs) in intensive care units (ICUs) result in poor clinical outcomes and increased costs. Although frequently regarded as preventable, infection risk may be influenced by non-modifiable factors. The objectives of this study were to evaluate organisational factors associated with CLABSI in Victorian ICUs to determine the nature and relative contribution of modifiable and non-modifiable risk factors. Data captured by the Australian and New Zealand Intensive Care Society regarding ICU-admitted patients and resources were linked to CLABSI surveillance data collated by the Victorian Healthcare Associated Infection Surveillance System between 1 January 2010 and 31 December 2013. Accepted CLABSI surveillance methods were applied and hospital/patient characteristics were classified as ‘modifiable’ and ‘non-modifiable’, enabling longitudinal Poisson regression modelling of CLABSI risk. In total, 26 ICUs were studied. Annual CLABSI rates were 1·72, 1·37, 1·00 and 0·93/1000 CVC days for 2010–2013. Of non-modifiable factors, the number of non-invasively ventilated patients standardised to total ICU bed days was found to be independently associated with infection (RR 1·07; 95% CI 1·01–1·13; P = 0·030). Modelling of modifiable risk factors demonstrated the existence of a policy for mandatory ultrasound guidance for central venous catheter (CVC) localisation (RR 0·51; 95% CI 0·37–0·70; P < 0·001) and increased number of sessional specialist full-time equivalents (RR 0·52; 95% CI 0·29–0·93; P = 0·027) to be independently associated with protection against infection. Modifiable factors associated with reduced CLABSI risk include ultrasound guidance for CVC localisation and increased availability of sessional medical specialists.

Background: Candida species have emerged as one of the most common causes of bloodstream infections (BSIs). There are limited data on the distribution of Candida spp. and susceptibility by year. Objectives: In this study, we analyzed changes in the distribution of Candida spp. and their antifungal susceptibility profiles from blood cultures. Methods: Records from January 2016 to December 2020 were obtained from the microbiology laboratory in Istanbul. Antifungal susceptibility tests were performed using the VITEK 2 compact system and evaluated according to EUCAST breakpoints. A total of 241 unique candidemia episodes were included in this study. Results: Candida albicans was the predominant pathogen (n = 95, 39.42%), followed by C. parapsilosis (n = 82, 34.02%), C. glabrata (n = 18, 7.47%), C. tropicalis (n = 17, 7.05%), C. krusei (n = 15, 6.22%), and other Candida spp. (n = 14, 5.79%). There was no statistically significant difference in the percentage of episodes of Candida spp. After data analysis, a tendency to shift from C. albicans to C. parapsilosis was observed in the period analyzed in this study. Candida albicans was the most common species in intensive care units (ICUs), hematology and hemopoietic stem cell transplantation units, and surgical clinics, with C. parapsilosis predominant in medical clinics. In general, micafungin susceptibility was the highest, and fluconazole was the lowest. There was reduced sensitivity to fluconazole and voriconazole for C. albicans and C. parapsilosis over 5 years. Conclusions: Detecting changes in the distribution of Candida spp. and antifungal susceptibility over time will lead to the selection of appropriate empirical therapy and monitor phenomena of antifungal resistance. Empirical treatment with antifungal agents is associated with high costs, toxicities, and risk of antifungal resistance. Therefore, it is mandatory to determine and monitor Candida spp. and antifungal susceptibility testing to select appropriate antifungal agents.

ABSTRACT BACKGROUND: Candida spp. secretes various extracellular hydrolytic enzymes. These enzymes are the important virulence factor for the pathogenesis of Candida. We assessed four different enzymatic activities of Candida isolates obtained from bloodstream infections. MATERIALS AND METHODS: We isolated 79 strains of different Candida species from the blood of the Intensive Care Unit-admitted patients. Species were identified by conventional methods including culture characteristic, germ tube, sugar assimilation, and Dalmau's culture technique. Phospholipase, proteinase, hemolysin, and esterase enzymatic activities were determined by the Plate method. RESULTS: Non albicans candida were the most common isolates from the blood of the ICU admitted patient with a predominance of Candida tropicalis. Hemolytic activity was the most prominent enzyme activity followed by the proteinase activity. Candida albicans (89.86%) was the major proteinase producer, while 95.8% of C. tropicalis produced hemolysin. No esterase activity was shown by the Candida glabrata and Candida krusei. CONCLUSION: No significant difference was observed between the two most common causative agents of candidemia: C. albicans and C. tropicalis.
