Objective: To determine the rates of colonization and infection related to central venous catheter (CVC), the causative microorganisms, and the influence of various factors. Methods: From June to August 1993, all CVC in 4 Intensive Care Units were evaluated from their insertion to removaL Data were collected by 3 nurses. Blood and catheter tips were cultured. ⋯ The most common microorganisms were gram-negative rods and S.aureus. Conclusions: The duration of venous catheter use increased the risk of colonization and infection. This observation suggests that physicians must strive for the shortest time of use of venous catheters, but it does not indicate a need for routine central venous catheter removal.
