Abstract
To determine risk factors for infection of hyperalimentation catheters, we prospectively studied 169 catheter systems (88 patients) by using a semiquantitative culture technique. Infection occurred in 24 (14%) catheters (16 patients), was inversely proportional to the number of previous catheters inserted by the operator (P < .02), and was proportional to the interval between admission and catheter insertion (P < .0005). Catheter replacement over a guidewire was no more likely to be associated with infection than was a de novo percutaneous insertion at another site (P = .6). Using a proportional hazards model, we estimated the risk of infection per day to be 1.3 times greater for a catheter if the patient had been hospitalized 50 days instead of seven days, and 3.8 times greater if the patient had a Swan-Ganz catheter at the time of insertion.
