  • Background:

    Catheter- line associated bloodstream infection (CLABSI) is a serious complication of patients on long term central venous catheters (CVC). Taurolidine-citrate solution (TCS) is a catheter-lock solution with broad- spectrum antimicrobial action that prevents biofilm formation. The aim of this study was to evaluate the efficacy of TCS in reducing CLABSI rate in pediatric patients with long-term CVC at a tertiary children’s hospital,

    Methods:

    This was an open-label trial of hematology-oncology (H/O) and gastrointestinal (GI) inpatients with the following inclusion criteria: Pediatric patients < 17 years of age, at least 1 previous CLABSI, required long-term CVC e.g. long-term parenteral nutrition or undergoing chemotherapy for malignancy and have a minimum dwell time of at least 8 hours for TCS. The period of surveillance was from each patient’s first CVC insertion till 14 December 2017 or discontinuation of TCS. CLABSI was calculated based on no. of CVC-associated BSI per 1000 catheter-days. Statistics were derived using SPSS 19.0 and the student T-test for paired samples and non-parametric Wilcoxon analysis for 2-Related-Samples Test with a p value of <0.05. OpenEpi v3.01 was used to compare 2 person-time rates and rate ratios with 95% confidence intervals,

    Results:

    34 patients were recruited with a median age of 3.4 years (IQR 1.5 to 10.1 years). H/O patients constituted 58.8% (n=20) and GI patients 41.2% (n=14). The majority of CVC were Hickman line (n=16, 47.1 %) followed by Port-a-Cath (n=8, 23.5%) and PICC (n=10, 29.4%). The median duration of TCS usage was 138 days (IQR 62.50- 307.25 days). The longest duration of TCS was 1737 days (4.8 years).

    Median pre and post-TCS CLABSI rates for the whole cohort, H/O and GI patients were 14.92±13.50 and 2.65±4.31 (p<0.001); 16.55 ± 12.96 and 2.81± 4.66 (p<0.001); 12.59 ± 14.39 and 2.42 ± 3.91 ( p=0.011) per 1000 catheter days respectively. For the whole cohort, pre and post-TCS rate ratio was 0.20 (95% CI 0.12-0.33, p< 0.001). TCS reduced markedly the risk of CLABSI for the whole cohort by 80%; for H/O patients by 79% and GI patients by 88%.

    Conclusion:

    Taurolidine-citrate solution was highly successful in reducing CLABSI rates by 80% in patients on long-term CVC with high baseline CLABSI rates.
