Rifampicin-miconazole-impregnated catheters save cost in jugular venous sites with tracheostomy.

Antimicrobial-impregnated catheters are more expensive than standard catheters (S-C). A higher incidence of catheter-related bloodstream infection (CRBSI) has been found in jugular venous access with tracheostomy than without tracheostomy. The objective of this study was to determine central venous catheter (CVC)-related costs (considering only the cost of the CVC, diagnosis of CRBSI, and antimicrobial agents used to treat CRBSI) using rifampicin-miconazole-impregnated catheters (RM-C) or S-C in jugular venous access with tracheostomy. We performed a retrospective cohort study of patients admitted to the intensive care unit (ICU) with tracheostomy who received one or more jugular venous catheters. RM-C showed a lower incidence of CRBSI compared with S-C (0 vs. 20.16 CRBSI episodes/1,000 catheter-days; odds ratio=0.05; 95% confidence interval=0.001-0.32; p<0.001) and lower CVC-related costs (including the cost of the CVC, diagnosis, and treatment of CRBSI) (11.46 ± 6.25 vs. 38.11 ± 77.25; p<0.001) in jugular venous access with tracheostomy. The use of RM-C could reduce CVC-related costs in jugular venous access with tracheostomy. The results of our study may contribute to clinical decision-making and selection of those patients who could benefit from the use of antimicrobial-impregnated catheters.
