Aim: Central line-associated bloodstream infection associated bloodstream infection (CLABSI) is a serious complication of patients on central venous catheters (CVC). Taurolidine-citrate solution (TCS) is a catheter-lock solution with broad-spectrum antimicrobial action. This study's aim was to evaluate the efficacy of TCS in reducing CLABSI rates in paediatric haematology-oncology (H/O) and gastrointestinal (GI) patients with long-term CVC. Methods:This was an open-label trial of H/O and GI inpatients with the following inclusion criteria: <17 years old, more than or equal to one previous CLABSI and a minimum TCS dwell time of ≥8 h. CLABSI per 1000 catheter-days was calculated from each patient's first CVC insertion till 14 December 2017 or until TCS discontinuation. Results: Thirty-three patients were recruited with a median age of 3.5 years; H/O and GI constituted 60.6 and 39.4% respectively. CVC types were Hickman line (45.5%), implantable port (24.2%) and peripherally inserted central catheter (30.3%). Mean pre-and post-TCS CLABSI rates per 1000 catheter-days were 14.44 and 2.45 (P < 0.001) for all patients; 16.55 and 2.81 for H/O patients; and 11.21 and 1.90 for GI patients, respectively. Pre-and post-TCS rate ratio was 0.20, 0.10 and 0.30 for all, H/O and GI patients, respectively (P < 0.001). TCS also led to a reduction in CVC removal from 66.7 to 9.09% (P < 0.001). Conclusions: TCS usage was highly successful in CLABSI reduction by 80% in all patients, 90% in H/O and 70% in GI patients. In patients with high baseline CLABSI rates, TCS is an effective catheter-lock therapy to reduce CLABSI rates in paediatric patients.
