Diagnosis and treatment of central venous access-associated infections.

This paper provides readers with a basic understanding of the types of central venous access-associated infections as well as appropriate diagnostic techniques. Preventive measures are the most effective way to reduce rates of catheter-associated infection and are discussed in detail. Diagnosis and treatment of each type of infection are reviewed for nontunneled central venous catheters, tunneled dialysis catheters, and venous access ports. Readers should be able to employ the methods described in this paper to reduce the rate of central venous access-associated infections at their hospitals.
