Dressing and securement for central venous access devices (CVADs): A Cochrane systematic review

Medication-impregnated dressing products reduce the incidence of CVAD-related bloodstream infection relative to all other dressing types. There is some evidence that chlorhexidine gluconate-impregnated dressings, relative to standard polyurethane dressings, reduce CVAD-related bloodstream infection for the outcomes of frequency of infection per 1000 patient days, risk of catheter tip colonisation and possibly risk of CVAD-related bloodstream infection. Most studies were conducted in intensive care unit settings. More, high quality research is needed regarding the relative effects of dressing and securement products for CVADs.
