Abstract

Background

Equivocal data demonstrate the efficacy of ethanol lock therapy (ELT) in preventing catheter-related bloodstream infections (CRBSIs) in home parenteral nutrition (HPN) patients, but it is not currently a standard of practice. The objective of this study is to investigate the efficacy of ELT in reducing the incidence of CRBSIs in HPN patients.

Methods

Medical records from the Cleveland Clinic database of adult HPN patients with CRBSIs placed on prophylactic ELT were retrospectively studied from January 2006 to August 2009 (n = 31). Outcomes were compared pre- and post-ELT with the patients serving as their own controls. Medical-grade (70%) ethanol was instilled daily into each lumen of the central venous catheter (CVC) between PN infusion cycles. Comparative analysis was performed using McNemar’s test and Wilcoxon ranked tests.

Results

Thirty-one patients had 273 CRBSI-related admissions prior to ELT in comparison to 47 CRBSI-related admissions post-ELT. Adjusted data for only tunneled CVC pre- and post-ELT showed a similar reduction of CRBSI-related admissions from 10.1 to 2.9 per 1000 catheter days (P < .001). There was also a statistically significant reduction in culture-positive CRBSIs and number of catheters changed pre- and post-ELT. There were no reported side effects or complications in any patient undergoing ELT.

Conclusions

This study supports the efficacy and safety of ELT in reducing CRBSI-related admissions in HPN patients and potentially helps reduce the burden of CRBSI-related healthcare costs. This novel technique shows great promise as a standard prophylaxis for CRBSI in HPN patients and must be incorporated in routine practice.
