Catheter-related infections (CRIs) are one of the most frequent healthcare-associated infections and are costly, morbid, and potentially lethal. A series of studies has confirmed that a comprehensive bundle approach based on known guidelines was successful in reducing catheter-related bloodstream infections in intensive care units. In this review, I'll summarize the previous recommendations made in 2002 on preventing CRIs and highlight recent advances and the evidences supporting novel methods of CRIs prevention published in research articles.

Central lines are indispensable in hospital care. The main complication resulting from their use is central line-associated bloodstream infection (CLABSI). CLABSI is one of the most frequent healthcare-associated infections associated with high costs, morbidity, and potential lethality. Recent studies on CLABSI prevention show that a multifaceted approach to improving central line insertion and maintenance practices results in decreased CLABSI rates. The question today, then, is not 'what to do,' but 'how to do it.'

Corynebacterium striatum is an aerobic, Gram-positive bacillus that is part of the resident flora of skin and mucosal membranes. C. striatum is usually considered a non-pathogenic contaminant, although infective endocarditis and respiratory infection, and less frequently arthritis and meningitis, due to C. striatum have been reported. C. striatum has been particularly associated with catheter-related infections and infections following conditions that resulted in disruption of the skin barrier in both immunocompromised and immunocompetent hosts. We describe a case of post-operative intra-abdominal infection caused by the rare pathogen, C. striatum.

Biofilms are commonly associated with an increased risk of catheter-associated infection. To study the efficacy of materials designed to reduce biofilm formation, microbial biofilms on clinically used urinary catheter were examined. We performed 2, 3-bis (2-methyoxy-4-nitro-5-sulfo-phenyl)-2H-tetrazolium-5-carboxanilide (XTT) reduction assay to determine of biofilm formation ability and observed with scanning electron microscopy (SEM) to analyze biofilm architecture. Additionally, we calculated relative cell surface hydrophobicity (CSH) to measure hydrophobicity of microorganisms. On SEM, catheter surfaces made of latex or anti-infective (IC)-latex were rough but those of silicone, hydrogel-coated silicone (HCS), or silver-alloy-coated silicone (SCS) were relatively smoother. According to XTT reduction assay, biofilm formation was reduced on the surface of smooth silicone-based catheters compared to rough latex-based catheters. The greatest to lowest formation of microbial biofilm were as follows for these material types: silicone-elastomer-coated (SEC) latex > latex > silicone > IC-latex > HCS > SCS. Catheter materials can affect the microbial biofilm formations. First, rougher surfaces on the catheter made the microbial attachment easier and a greater amount of biofilm was formed. Second, when chemicals that inhibit growth and attachment of microorganisms on the inner and outer surfaces of the catheters were applied, the biofilm formation was inhibited. SCS was found to be the most effective in reducing the microbial biofilm formation. These results indicate that microbial biofilm formation may be closely related to the surface roughness and microbial CSH.

Use of central venous catheters (CVCs) can lead to catheter-related bloodstream infections (CRBSIs) and such infections are associated with serious morbidity and mortality and with increased health care costs. The diagnosis of CRBSI needs to be accurate for adequate management. Semiquantitative catheter tip culture has been established as standard in most laboratories, but this method requires catheter removal. Catheter-sparing diagnostic methods, such as differential quantitative blood cultures and differential time to positivity have emerged as reliable diagnostic techniques. Management of CRBSIs involves deciding on catheter removal and the type and duration of systemic antimicrobial therapy. Such decisions depend on the identity of the organism causing the bloodstream infection and the clinical and radiographic manifestations suggesting a complicated course.

PURPOSE: The purpose of this study was to examine the effect of maximal sterile barrier precaution on the central venous catheter-related infection and subsequent cost savings. METHODS: Study subjects were 462 hospitalized patients with central venous, catheter of more than 48 hours duration. Data collection period was from April 2008 to February 2009 at a tertiary university hospital in Seoul. Subjects were randomly assigned to either the treatment or the usual care group. Patients in the treatment group (n=209) were treated by staff using maximal sterile barrier precautions and the comparison group(n=253) received traditional care. RESULTS: Central venous catheter-days was2,821 in treatment group and 3,515 in comparison group. The incidence density of central venous catheter-related infection was 2.1 times higher in the comparison group (8.2 per 1,000 catheter-days) compared with the treatment group (3.9 per 1,000 catheter-days). The incidence density of central venous catheter-related bloodstream infection was 4.54 times higher than in the comparison group (3.2 per 1,000 catheter-days) compared with the treatment group (0.7 per 1,000 catheter-days). The attributable cost of central venous catheter-related infection in the treatment group was 10,174,197 won and that of the comparison group was 22,224,554 won. Attributable cost by area was also significantly lower compared with that of the comparisons. CONCLUSION: The maximal sterile barrier precaution during central venous catheter insertion was an effective intervention to reduce central venous catheter-related infection rate and provides a significant cost savings.
