The clinical usefulness of hemodialysis catheters is limited by increased infectious morbidity and mortality. Topical antiseptic
agents, such as mupirocin, are effective at reducing this risk but have been reported to select for antibiotic-resistant strains.
The aim of the present study was to determine the efficacy and the safety of exit-site application of a standardized antibacterial
honey versus mupirocin in preventing catheter-associated infections. A randomized, controlled trial was performed comparing
the effect of thrice-weekly exit-site application of Medihoney versus mupirocin on infection rates in patients who were
receiving hemodialysis via tunneled, cuffed central venous catheters. A total of 101 patients were enrolled. The incidences of
catheter-associated bacteremias in honey-treated (n 51) and mupirocin-treated (n 50) patients were comparable (0.97 versus
0.85 episodes per 1000 catheter-days, respectively; NS). On Cox proportional hazards model analysis, the use of honey was not
significantly associated with bacteremia-free survival (unadjusted hazard ratio, 0.94; 95% confidence interval, 0.27 to 3.24; P
0.92). No exit-site infections occurred. During the study period, 2% of staphylococcal isolates within the hospital were
mupirocin resistant. Thrice-weekly application of standardized antibacterial honey to hemodialysis catheter exit sites was
safe, cheap, and effective and resulted in a comparable rate of catheter-associated infection to that obtained with mupirocin
(although the study was not adequately powered to assess therapeutic equivalence). The effectiveness of honey against
antibiotic-resistant microorganisms and its low likelihood of selecting for further resistant strains suggest that this agent may
represent a satisfactory alternative means of chemoprophylaxis in patients with central venous catheters.
