R E V I E Wfeedback is provided to all actors [7,8]. Catheter insertion in emergency conditions increases the risk of non-compliance to the insertion protocol and, consequently, to infectious complications; these catheters must be replaced as soon as the patient's condition is stabilized [9].
Staff educational/quality improvement programEducating and training of health-care providers who insert and maintain CVCs is essential for preventing catheter-related infection, improving patient outcomes, and reducing healthcare costs [10]. Th e experience of the operator is an important issue as the risk of infectious complications is inversely proportional to the operator skills. An educational intervention in catheter insertion signifi cantly improved patient outcomes and simulationbased training programs are valuable in residency education [11]. Programs for training nurses in longterm catheter care ("IV teams") were associated with a reduction in catheter-related infections in the USA [12]. Nevertheless, without such teams the use of care protocols and nursing staff education allowed comparable results to be obtained [13]. Nursing staff reductions below a critical level may contribute to increase catheterrelated infection by making adequate catheter care diffi cult. One study reported a four times greater risk of catheter infection when the patient-to-nurse ratio was doubled [14]. Moreover, replacement of regular nurses by fl oat nurses further increases the risk of device-related infections [15]. Th ese studies clearly indicate that trained nurses, in suffi cient numbers, must be available for optimal patient care in the ICU.
Type of catheterCatheter material is an important determinant in the prevention of catheter-related infection. Th e material should be biocompatible, hemocompatible, biostable, chemically neutral, not altered by administered drugs, and deformable according to surrounding strengths. Furthermore, the catheter ...
