Infection | Definition |
Catheter colonization | Significant growth of ≥1 micro-organism in a quantitative or semiquantitative culture of the catheter tip, subcutaneous catheter segment, or catheter hub. |
Phlebitis | Induration or erythema, warmth, and pain or tenderness along the tract of a catheterized or recently catheterized vein. |
Exit site infection | |
Microbiologic | Exudate at catheter exit site yields a micro-organism with or without concomitant bloodstream infection. |
Clinical | Erythema, induration, and/or tenderness within 2 cm of the catheter exit site; may be associated with other signs and symptoms of infection, such as fever or purulent drainage emerging from the exit site, with or without concomitant bloodstream infection*. |
Tunnel infection | Tenderness, erythema, and/or induration >2 cm from the catheter exit site, along the subcutaneous tract of a tunneled catheter (eg, Hickman or Broviac catheter), with or without concomitant bloodstream infection*. |
Pocket infection | Infected fluid in the subcutaneous pocket of a totally implanted intravascular device; often associated with tenderness, erythema, and/or induration over the pocket; spontaneous rupture and drainage, or necrosis of the overlying skin, with or without concomitant bloodstream infection*. |
Bloodstream infection | |
Catheter related | Bacteremia or fungemia in a patient who has an intravascular device and >1 positive blood culture result obtained from the peripheral vein, clinical manifestations of infection (eg, fever, chills, and/or hypotension), and no apparent alternative source for bloodstream infection (with the exception of the catheter). |
Infusate related | Concordant growth of a micro-organism from infusate and cultures of percutaneously obtained blood cultures with no other identifiable source of infection. |
