  Purpose

Intravascular devices are an integral component of modern-day medical practice. Infection is one of the leading complications of intravascular catheters and is associated with an increased mortality, prolonged hospitalization and increased medical costs. Central venous catheters (CVCs) account for an estimated 90% of all catheter-related bloodstream infections (CRBSI). A host of risk factors for CVC-related infections have been documented. This includes most importantly, duration of catheterization. The duration of use of CVCs remains controversial and the length of time such devices can safely be left in situ has not been fully and objectively addressed in the critically ill patient. As a consequence, scheduled replacement remains widely practiced in many Intensive Care Units(ICUs). Over the past few years, antimicrobial impregnated catheters have been introduced in an attempt to limit catheter-related infection (CRI) and increase the time that CVCs can safely be left in place. Recent meta-analyses concluded that antimicrobial impregnated CVCs appear to be effective in reducing CRI. The topic however, remains extremely controversial with different viewpoints appearing in the literature recently.

This was a prospective randomized double-blind study performed in the multidisciplinary ICU at Johannesburg Hospital over a four year period.The study entailed a comparison of standard triple-lumen versus antimicrobial impregnated CVCs on the rate of CRI. The aim was to determine whether the researchers could safely increase the duration of catheter insertion time from the standard practice of seven days to 14 days, to assess the influence of the antimicrobial impregnated catheter on the incidence of CRI, evaluate risk factors and elucidate the epidemiology of CRI.
