The following information is from the 2008 Society for Healthcare Epidemiology of America and Infectious Disease Society of America Practice Recommendation: Strategies to Prevent Healthcare-Associated Infections in Acute Care Hospitals. (Infect Control Hosp Epidemiol 2008;29:S22-S30.)
Each recommendation is categorized on the basis of existing scientific data, theoretical rationale, applicability, and economic impact. Category A-I recommendations are strongly recommended for implementation and strongly supported by well-designed experimental, clinical, or epidemiologic studies.
Use appropriate hand hygiene
Bottom line: Proper hand hygiene is required before and after palpating catheter insertion sites as well as before and after inserting, replacing, accessing, repairing, or dressing an intravascular catheter. In addition, the use of gloves does not obviate the need for hand hygiene. Category B-II
Since 1977, at least seven prospective studies have shown that improvement in hand hygiene significantly decreases a variety of infectious complications. Proper hand hygiene procedures can be achieved through the use of either a waterless, alcohol-based product or antibacterial soap and water with adequate rinsing. Compared with peripheral venous catheters, CVCs carry a substantially greater risk for infection; therefore, the level of barrier precautions needed to prevent infection during insertion of CVCs should be more stringent than proper hand hygiene alone.

Use chlorhexidine for skin preparation
Bottom line: Disinfect clean skin with an appropriate antiseptic before catheter insertion and during dressing changes. An alcoholic chlorhexidine solution containing a concentration greater than 0.5 percent is preferred. Category A-I
In a study from 1991, preparation of central venous and arterial sites with a 2 percent aqueous chlorhexidine gluconate lowered blood stream infection rates compared with site preparation with 10 percent povidone-iodine or 70 percent alcohol. Since that time, there has been growing evidence that chlorhexidine-containing skin preparation is superior to other options. A meta-analysis from 2002 that pooled results of these studies demonstrated use of a chlorhexidine-containing preparation decreased central catheter-related infections by 49 percent relative to povidone-iodine preparations. Because a smaller effect of chlorhexidine was seen in studies using a 0.5 percent concentration of chlorhexidine, preparations with greater concentrations are recommended.

Use full-barrier precautions during CVC insertion
Bottom line: Maintain aseptic technique for the insertion of intravascular catheters. Category A-I
Maximal sterile barrier precautions (e.g., cap, mask, sterile gown, sterile gloves, and large sterile drape) during the insertion of CVCs substantially reduces the incidence of CLABSI compared with standard precautions (e.g., sterile gloves and small drapes).

Avoid using the femoral vein for CVCs in adult patients
Bottom line: Use of the femoral site is associated with greater risk of infection and deep venous thrombosis in adults. Category A-I
The site at which a catheter is placed influences the subsequent risk for catheter-related infection and noninfectious complications. For adults, lower extremity insertion sites are associated with a higher risk for infection than are upper extremity sites. As a result, authorities recommend that the femoral vein be avoided. Place CVCs in an alternative site to reduce the risk for infection. The risk of noninfectious complications should be assessed on an individual basis when determining which site to place the CVC.

Remove unnecessary CVCs
Bottom line: Promptly remove any intravascular catheter that is no longer essential. Category A-II
One of the most effective strategies for preventing CLABSIs is to eliminate or at least reduce exposure to CVCs. The decision regarding the need for a catheter is complex, however, and difficult to standardize into a practice guideline. Nonetheless, to reduce exposure to CVCs, the multidisciplinary team should adopt a strategy to systematically evaluate daily whether any catheters or tubes can be removed.
