Preemptive Ethanol Lock Therapy in Pediatric Hematology/Oncology Patients With Catheter-Associated Bloodstream Infection: Impact on Length of Stay, Cost, and Catheter Salvage.

ABSTRACT: BACKGROUND:Ethanol lock therapy (ELT) with systemic antimicrobial therapy is a promising therapy for catheter-related infection (CRI). The impact of ELT timing on treatment efficacy and costs is unknown. PROCEDURES:A prospective study was conducted in the Hematology/Oncology Unit at the Children's Hospital of Michigan. Patients with suspected CRI were randomized to Preemptive ELT arm or Rescue ELT arm after positive culture. RESULTS:Five cases in Preemptive arm and 9 in Rescue arm had a confirmed CRI. All cases cleared infection with line salvage with no adverse events due to ELT or recurrence within 14 days. Our data showed a trend toward 36% reduction in average hospital costs and 40% reduction in average length of stay in Preemptive arm over Rescue arm. CONCLUSION:Although a small study, our data on preemptive ELT with systemic antimicrobial therapy suggest a potentially important treatment strategy in reducing length of stay as well as hospital costs.

Project description:Abstract Background Central line-associated bloodstream infection (CLABSI) commonly affects children with cancer and hematological disorders, with significant attributable costs and morbidity. Treatment failure, comprising persistent infection, infection relapse or new infection, occurs in ~50% of cases. Adjunctive ethanol lock therapy (ELT) has been proposed to prevent failure, but has never been tested in a prospective controlled study. Methods A prospective, dual-center, double-blind, block-randomized, placebo-controlled trial of ELT (70% ethanol in water) for CLABSI, given as treatment (2 hours per lumen per day) for 5 days, followed by secondary prophylaxis (2 hours per lumen up to 3 days per week) for 24 weeks, in children with oncologic or hematologic disorders (NCT01472965). Risk of treatment failure was compared between intervention and control groups according to proportional and cumulative incidence models, using intention-to-treat and per-protocol analyses. The study was discontinued at a pre-specified futility analysis. Results Of 94 evaluable participants, 48 were randomized to ELT and 46 to placebo; groups were similar at baseline for all measured variables. Forty-one (43.6%) participants had treatment failure (11 early failure, 9 relapse, and 21 reinfection). There was no difference between patients receiving ELT or placebo for risk of treatment failure (43.8% vs. 43.5%; P = 0.9) or for cumulative incidence of treatment failure in intention to treat (Figure 1) and per-protocol analyses (Figure 2). Catheter occlusion was significantly more common in participants receiving ethanol (58.3% vs. 32.6%, P = 0.01) but other adverse events, including LFT elevations (14.6% vs. 26.1%) and infusion reactions (18.8% vs. 8.7%), were not significantly different between groups. Conclusion Although observational studies suggested ELT might be effective for treatment of CLABSI in pediatric oncology, we found no benefit in treatment outcome and an increase in adverse effects. These results may not apply to patients receiving dialysis or with fungal CLABSI as these were not well-represented. Routine use of ELT for CLABSI in children with oncologic or hematologic disorders is not recommended. Disclosures All authors: No reported disclosures.
