Central venous catheters are a principal source of nosocomial bloodstream infections, which are difficult to control.
To determine the efficacy of catheters coated with minocycline and rifampin in preventing catheter-related colonization and bloodstream infections.
Multicenter, randomized clinical trial.
Five university-based medical centers.
281 hospitalized patients who required 298 triple-lumen, polyurethane venous catheters.
147 catheters were pretreated with tridodecylmethyl-ammonium chloride and coated with minocycline and rifampin.
Untreated, uncoated catheters (n=151) were used as controls.
Quantitative catheter cultures, blood cultures, and molecular typing of organisms to determine catheter-related colonization and bloodstream infections.
The group with coated catheters and the group with uncoated catheters were similar with respect to age, sex, underlying diseases, degree of immunosuppression, therapeutic interventions, and risk factors for catheter infections.
Colonization occurred in 36 (26%) uncoated catheters and 11 (8%) coated catheters (P<0.001).
Catheter-related bloodstream infection developed in 7 patients (5%) with uncoated catheters and no patients with coated catheters (P<0.01). (...)
