title: Intravascular device-related infections in critically ill patients.
abstract: Intravascular device-related infections (IVDRIs) are among the most common nosocomial infections in critically ill patients. Quantitative or semi-quantitative microbiology diagnosis is necessary for their management. Most causative organisms arise from the skin; staphylococci are responsible for two-thirds of the IVDRIs, with Staphylococcus aureus responsible for 5% to 15%. Complications may include septic shock, suppurative thrombophlebitis, and endocarditis. In critically ill patients, intravenous lines are responsible for at least 23% of nosocomial bloodstream infection, which has a mortality of 25% and is associated with a longer stay in intensive care and costs $28,960 per survivor. IVDRIs can be treated with intravenous antibiotics without removing the device, but removal of the catheter is recommended. Prevention is based on careful insertion practice and optimal catheter care. Systemic replacement of the intravenous lines every three to five days is common practice in the USA but not elsewhere in Europe. This issue should be studied, particularly in critically ill patients.
