Recommended: Catheter bloodstream infection and literature review

BioPatch, and alternatives like Tegaderm CHG, are an important first step in helping prevent catheter-related bloodstream infections (CBIs). As CBIs rank among the most frequent and potentially lethal nosocomial infections, the need for a device to cut down infections at the insertion site has increased. The growing numbers of infections has driven companies to consider a three-tiered approach: a maximal aseptic barrier at insertion, proper site maintenance, and hub protection. With BioPatch and alternative products catheter sites receive that maximal aseptic barrier to prevent bacteria growth.

Catheter-Related Bloodstream Infections
According to an article by Timsit, J., et al. an estimated 5 million central venous catheters are inserted in patients each year. CBIs, most of which are associated with central venous catheters, account for more than 11% of all health-care associated infections. Additionally, more than 250,000 central-line associated blood stream infections also occur annually, with an estimated mortality rate of 12-25%. For patients within the intensive care unit, the numbers were even higher. Each episode significantly increases the patient’s hospital stay, as well as increasing costs from $4,000 to $56,000 per episode.

CBIs occur when intravascular devices become contaminated on the outer surface during nonaseptic insertion or with improper maintenance of the catheter exit site. CBIs are commonly associated with sepsis, fever, chills and hypotension. Skin flora at the insertion site is the most common source of catheter colonization.

According to manufacturer-funded evidence, Tegaderm CHG is extremely effective at reducing the skin flora regrowth, or biofilm, that builds up underneath catheter dressings. Additionally, biofilm is a major source of CRBSI’s within the first week of build-up; biofilm is also a major source of tunnel exit site infections in long-term catheters. Again, according to manufacturer-funded studies Tegaderm has been proven extremely effective at reducing the biofilm build-up.

A final distinction between BioPatch and Tegaderm CHG is in design. Tegaderm CHG is built with a clear CHG-gelpad which is secured to the patient with special adhesive. Because Tegaderm CHG is clear, while BioPatch is built with a CHG-infused sponge, this makes it easier for hospital faculty to be able to check the dressings need to be replaced due to any build-up.

    Prof. Amanda Ellis: The problem with catheters is the ability to get bacterial attachment to the surface of the polymer. There are two approaches to this problem using nanotechnology: coating or copolymerization. The approach of the coating works when an antimicrobial layer is placed on top of the lens. The antimicrobial the Flinders Research team has been using is an extract from cloves. Dentists have also been using this compound to stop oral infections. The other approach is when the antimicrobial agent is combined with the polymer and this is called ‘copolymerization’. The reason why copolymerization is more effective is the coating can be abraded off. However with the copolymerization the antimicrobial is part of the compound and forms covalent bonds (share of electrons). It is important that the bonds are strong as the material could come out of the polymer and cause even more damage.

    5), many hospitals in conjunction with the Joint Commission's 2012 National Patient Safety Goals has been rallying for hospitals to use evidenced-based practices (EBP) to the prevention of CAUTIs because evidence is growing showing that many are avoidable. Such practices such as utilizing a nurse-driven protocol to assess and evaluate the appropriateness and use of urethral catheter to determine how long a patient should have an indwelling catheter and when to discontinue it. Several factors have been identified that pose as risk factors to CAUTI which include but not limited to drainage bag not being below the level of the bladder, healthcare personnel not practicing standard precautions and utilizing aseptic techniques during insertion of catheters, unsterile equipment, and unnecessary placement of urinary

    2013). Inappropriate use of urinary catheter in patients as stated by the CDC includes patients with incontinence, obtaining urine for culture, or other diagnostic tests when the patient can voluntarily void, and prolonged use after surgery without proper indications. Strategies used focused on initiating restrictions on catheter placement. Development of protocols that restrict catheter placement can serve as a constant reminder for providers about the correct use of catheters and provide alternatives to indwelling catheter use (Meddings et al. 2013). Alternatives to indwelling catheter includes condom catheter, or intermittent straight catheterization. One of the protocols used in this study are urinary retention protocols. This protocol integrates the use of a portable bladder ultrasound to verify urinary retention prior to catheterization. In addition, it recommends using intermittent catheterization to solve temporary issues rather than using indwelling catheters. Indwelling catheters are usually in for a longer period. As a result of that, patients are more at risk of developing infections. Use of portable bladder ultrasound will help to prevent unnecessary use of indwelling catheters; therefore, preventing

Often times these lines are placed in emergent situations in the emergency department (ED) and there may be a break in sterile technique. However a study conducted by Smith, Egger, Franklin, Harbrecht, and Richardson (2011) found a higher incidence of CLABSIs among intensive care unit (ICU) patients compared to those patients whose CLs were placed either in the ED or operating room (OR).

    The significant increase in antibiotic resistance amongst pathogens is making it very difficult to successfully treat infections, especially in intensive care units (ICU’s). Prevention of the spread of infection among patients within the hospitals is fast becoming amongst the most important methods for controlling infections. This requires the identification of the different acquisition routes, that is, routes by which bacterial colonization occurs. In this article, the authors analyzed the relative importance of various bacterial acquisition routes that resulted in colonization of the bacteria using data from individual patients.[1] This article was chosen because of the impact it can have on the healthcare system if the knowledge obtained from the algorithm regarding the most prevalent colonization routes in hospitals can help in the preventing spread of infections. Also the ability of the algorithm to incorporate specific patient characteristics makes it both novel and appealing.

    Hospital acquired infections are spread by numerous routes including contact, intravenous routes, air, water, oral routes, and through surgery. The most common types of infections in hospitals include urinary tract infections (32%), surgical site infections (22%), pneumonia (15%), and bloodstream infections (14%). ( book). The most common microorganisms associated with the types of infections are Esherichila coli, Enterococcus species, Staphylococcus auerus, Coagulase-negative staphylococci, or Pseudomonas aeruginosa.(secondary) Urinary tract infections occur when one or more of microorganisms enter the urinary system and affect the bladder and/or the kidneys. These infections are often associated improper catheterization technique. Surgical site infections occur after surgery in the part of the body where the surgery took place. These infections may involve the top of the skin, the tissue under the skin, organs, or blood vessels. Surgical site infections sometimes take days or months after surgery to develop. The infections can be cause by improper hand washing, dressing change technique, or improper surgery procedure. Pneumonia can also become a hospital acquired infection.
