We have seen a successful reduction in Central line associated bloodstream infection related the past decade. In spite of this, Intensive care unit-Catheter related bloodstream infections remain high. The emergence of new pathogens further complicates treatment and threatens patient outcomes in this context. In addition, the SARS-CoV-2 (COVID-19) pandemic served as a reminder that an emerging pathogen poses a challenge for adjusting prevention measures regarding both the risk of exposure to caregivers and maintaining a high level of care. ICU nurses play an important role in the prevention and management of CLABSI as they are involved in basic hygienic care, quality improvement initiatives, microbiological sampling, and aspects of antimicrobial stewardship. Microbiological techniques that are more sensitive and our increased knowledge of the interactions between critically ill patients and their microbiota are forcing us to rethink how we define CLABSIs and how we can diagnose, treat, and prevent them in the ICU. The objective of this multidisciplinary expert review, focused on the ICU setting, is to summarize the recently observed occurrence of CLABSI in ICU, to consider the role of modern microbiological techniques in their diagnosis, to examine clinical and epidemiological definitions, and to redefine several controversial preventive measures including antimicrobial-impregnated catheters, chlorhexidine-gluconate impregnated sponge, and catheter dressings.展开更多

However, the use of CVCs is associated with substantial risk of infection. Central line associated bloodstream infection (CLABSI) is increasing in prevalence each year and is among the major causes of bloodstream infection in ICU patients. Therefore, investigating the epidemiology and risk factors of CLABSI in ICU patients is important. Objective: This study aimed to investigate the incidence rates, causative pathogens and risk factors of CLABSI in an ICU population. Methods: A retrospective observational study was performed in an ICU at Qilu Hospital of Shandong University in China from January 2016 to December 2020. Patients with at least one CVC were enrolled, and information relevant to CVC use was recorded. The prevalence was calculated, and related risk factors were analyzed. Results: A total of 1920 catheters were identified, 507 of which were eligible for analysis. For each of the years 2016-2020, the incidence rates of CLABSI were 1.91, 3.18, 1.69, 2.97 and 1.27 per 1000 catheter days, respectively. The yeast Candida albicans was the most prevalent pathogen (16 [(3.2%]), followed by Gram-positive methicillin-resistant Staphylococcus aureus (11 [2.2%]) and the Gram-negative multidrug-resistant pathogen Acinetobacter baumanii. Risk factors associated with CLABSI development were age, (p = 0.05), Charlson comorbidity index > 5 (p Conclusion: Candida albicans was the most common causative microorganism, which was followed by Gram positive methicillin resistant Staphylococcus, MDR K. pneumoniae and Acinetobacter baumanii.展开更多

However, the prevention and control status of CLABSI in hospitals of different grades in Guangxi is not clear. In this study, we aim to investigate central venous catheter (CVC) placement and disinfectant use in second and third-level hospitals in Guangxi. This survey was conducted on the second and third-level hospitals in Guangxi, China from 13th April 2021 to 19th April 2021. The results show that a total of 283 questionnaires were collected, including 206 secondary hospitals and 77 tertiary hospitals. In terms of the CVC, tertiary hospitals were able to place CVC entirely under the guidance of B-ultrasound, which was 24 (31.6%) and secondary hospitals were 26 (20.6%). In secondary hospitals, Most CVC placements were performed in operating rooms 94 (74.6%) and 65 (85.5%) on the third level hospital, but 32.5% of secondary hospitals and 48.7% of tertiary hospitals were selected at the bedside of patients in general wards, and 27.8% of the second-level hospital, 43.4% of third-level hospitals was done in general ward treatment rooms, only 61.9% of secondary hospitals and 64.5% of tertiary hospitals could fully achieve the maximum sterile barrier. In terms of skin disinfectants, only 36.0% of tertiary hospitals and 16.4% of second-level CVC-operators chose > 0.5% chlorhexidine alcohol. In conclusion, the prevention and control of catheter line-associated bloodstream infections (CLABSI) in Guangxi are not ideal. The prevention and control department should increase training, implement guidelines and standardize management to reduce the incidence of CLABSI.展开更多

RESULTS We followed 776 ICU patients for 4818 bed-days. The central line-associated bloodstream infection(CLABSI) rate was 6.5 per 1000 central line(CL)-days, the ventilator-associated pneumonia(VAP) rate was 44.3 per 1000 mechanical ventilator(MV)-days, and the catheterassociated urinary tract infection(CAUTI) rate was 5.7 per 1000 urinary catheter(UC)-days. CLABSI and CAUTI rates in our ICUs were similar to INICC rates [4.9(CLABSI) and 5.3(CAUTI)] and higher than NHSN rates [0.8(CLABSI) and 1.3(CAUTI)]- although device use ratios for CL and UC were higher than INICC and CDC/NSHN's ratios. By contrast, despite the VAP rate was higher than INICC(16.5) and NHSN's rates(1.1), MV DUR was lower in our ICUs. Resistance of A. baumannii to imipenem and meropenem was 75.0%, and of Pseudomonas aeruginosa to ciprofloxacin and piperacillin-tazobactam was higher than 72.7%, all them higher than CDC/NHSN rates. Excess length of stay was 7.4 d for patients with CLABSI, 4.8 for patients with VAP and 9.2 for patients CAUTI. Excess crude mortality in ICUs was 30.9% for CLABSI, 14.5% for VAP and 17.6% for CAUTI. CONCLUSION DA-HAI rates in our ICUs from Ecuador are higher than United States CDC/NSHN rates and similar to INICC international rates.展开更多
